AB  - The influence of welding current and nitrogen content in argon shielding gas on the resistance of the welded joint (weld metal and heat-affected zone [HAZ]) of the stainless steel X5CrNi18-10 to the formation and growth of pits was investigated. Also, the susceptibility of the welded joint to intergranular corrosion was examined. Pitting corrosion resistance indicators were determined based on anodic potentiodynamic polarization measurements in NaCl + Na2SO4 solution, while susceptibility to intergranular corrosion was determined by the potentiokinetic method with a double loop (DL EPR). SEM/EDS was used to analyze the microstructure. It has been shown that higher nitrogen content in shielding gas leads to an increase in the resistance of welded joints (weld metal and HAZ) to the pit formation. However, an improvement in the resistance to the pit formation leads to a decline in the resistance of the welded joint to pit growth. An explanation of this phenomenon is proposed. Also, it was shown that the increase of the welding current increases the susceptibility of the welded joint to intergranular corrosion, while the higher nitrogen content has no effect.

AB  - This paper examined the degree of sensitization (DOS) to intergranular corrosion (IGC) and the level of electrical conductivity of the welded and non-welded AISI 304 stainless steel to obtain a suitable correlation. The DOS was determined by the double loop electrochemical potentiokinetic reactivation method (DL EPR), while the level of electrical conductivity was measured using a commercial device (non-destructive method). After electrochemical etching in oxalic acid, the microstructure of the specimen surface was analyzed by scanning electron microscopy (SEM). At DOS greater than ~ 0.5%, a clear linear dependence between the electrical conductivity and the value of the DOS was obtained, while there was a higher deviation from linearity for lower DOS values. The mentioned correlations were discussed in the sense of the precipitation kinetics of the Cr-carbide and the formation of Cr-depleted areas of different levels near the grain boundaries. Cr-depleted areas during anodic polarization measurements show lower resistance to pit formation. The presence of Cr-depleted areas in the vicinity of grain boundaries and the reduction of carbon content in the austenite crystal lattice increases the electrical conductivity of the stainless steel.

AB  - The AISI 304 (X5CrNi19‐10) stainless steel is widely used for the production of
various metal parts in power plants. A procedure for testing the influence
of the dust from a power plant on resistance to general and pitting corrosion of
the AISI 304 stainless steel is developed and performed. The quantitative (XRD
method) and qualitative (Fourier–transform infrared spectroscopy [FTIR]
method) composition of the dust present in the power plant is determined.
Applying the Mott–Schottky method, the properties of the passive layer are
analyzed, while a degree of chromium depletion of the grain boundary is
determined by the electrochemical potentiokinetic reactivation method with
double loop method. Values of polarization resistance (linear polarization
resistance and electrochemical impedance spectroscopy methods) and the
corrosion current density (polarization measurements) indicate that the
stainless steel has a higher resistance to general corrosion in the dust solutions
than in the etalon solution. Also, based on the measured value of the pitting
potential (Epit) and the difference between the values of the pitting potential
and the corrosion potential (Epit – Ecorr), it can be seen that stainless steel has a
higher resistance to localized types of corrosion, such as pitting corrosion, in
dust solutions than in the etalon solution.

AB  - The efficacy of the environmentally friendly corrosion inhibitor Ce-citrate (0.1-0.5 mM) was analyzed on AISI 4130 low alloy carbon steel and AA7075 aluminum alloy in 0.05 M NaCl solution. Measurements of resistance to general corrosion were performed by electrochemical impedance spectroscopy and potentiodynamic polarization test. Resistance to pitting corrosion is determined based on the value of pitting potential Epit. For comparison, corrosion resistance measurements and pitting potential determination, for considered alloys, were performed in Ce-chloride solution. Changes on the surface of the specimens after corrosion testing were analyzed by SEM microscopy. The XPS method was used for the analyses of the formed inhibitory layer on the steel specimen surface. It has been shown that significant amounts of cerium, as well as the citrate anions, are present in the inhibitory layer. Ce-citrates have proved to be an effective corrosion inhibitor for AISI 4130 steel as well as an effective pitting corrosion inhibitor for AA7075 aluminum alloy. The mechanism of action of Ce-citrate on AISI 4130 steel and AA7075 aluminum alloy has been proposed.

The corrosion resistance of AA7075 alloy was tested electrochemically using electrochemical impedance spectroscopy (EIS). Significantly higher polarization resistance in inhibitor-containing solution, along with phase angle peak shift to more negative values, indicate good corrosion inhibition by Nd-cysteine. The morphology, analyzed by scanning electron microscopy (SEM/EDS), showed that the surface of the AA7075 alloy was wholly protected from corrosion after 24h in NaCl solution.

AB  - The aim of this study was to investigate environmentally-friendly corrosion inhibitors based on the cerium-cysteine and their effect on 7xxx series aluminum alloy. The cysteine and cerium-cysteine complex structures were analyzed by Fourier-Transform Infrared spectroscopy (FTIR). The structure of cerium-cysteine was additionally determined using Nuclear Magnetic Resonance (NMR) and Elemental Analysis. Inhibitors efficiency was analyzed with Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic polarization techniques in 0.1M NaCl at room temperature, while Scanning Electron Microscopy analyzed the surface appearance and microstructure of the tested aluminum alloy with Energy Dispersive Spectroscopy (SEM / EDS) and Optical Microscope (OM). Different amounts of cysteine were examined in order to find an optimal concentration of inhibitor. The adsorption of the inhibitors followed the Langmuir isotherm, and based on the EIS results and calculated thermodynamic potential (Gibbs free energy), cysteine and cerium-cysteine proved to be good inhibitors for tested aluminum alloy. The optimal cysteine concentration of 0.06 mM as a corrosion inhibitor of 7xxx series aluminum alloy was determined. EIS diagrams confirmed that cysteine showed better inhibition than Ce-Cys complex.

For this purpose different concentrations of corrosion inhibitor were analyzed in the range of 0.1-0.5 mM. Electrochemical impedance spectroscopy and potentiodynamic polarization test were used for measurements of resistance to general corrosion. Pitting potential Epit value was used for the determination of resistance to pitting corrosion.

abstract = "The corrosion protective properties of environmentally friendly Ce-citrate were analyzed on AISI 4130 low alloy carbon steel and AA7075 aluminum alloy in 0.05 M NaCl solution. For this purpose different concentrations of corrosion inhibitor were analyzed in the range of 0.1-0.5 mM. Electrochemical impedance spectroscopy and potentiodynamic polarization test were used for measurements of resistance to general corrosion. Pitting potential Epit value was used for the determination of resistance to pitting corrosion. Additionally, corrosion resistance measurements and determination of pitting potential value were performed in Ce-chloride solution with the aim of comparation. SEM microscopy was used for the determination of changes on the surface of the specimens after corrosion testing. The XPS method was used for the analyses of the formed inhibitory layer on the steel specimen surface. It has been shown that significant amounts of cerium, as well as the citrate anions, are present in the inhibitory layer.

AB  - The inhibitory effect of cysteine in the presence of selected lanthanide chlorides (LaCl3, NdCl3, and CeCl3) in a neutral 0.1M NaCl solution was analyzed. The cysteine concentration of 0.3mMwas determined as an optimal one. The resistance to general and pitting corrosion of AA7075‐T6 alloy in inhibitive solutions was determined using electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The surface appearance of the aluminum alloy was determined before and after corrosion tests using scanning electron microscopy/energy dispersive spectroscopy, while the presence of an inhibitory layer on the alloy surface was confirmed by X‐ray photoelectron spectroscopy analysis and atomic force microscopy. The inhibitory effect of cysteine was significantly higher in the presence of all tested lanthanide chlorides, especially to pitting corrosion. The protective ability of cysteine was increased by lanthanides in the following sequence: Ln<Nd <Ce ions. The inhibitory effect of cysteine in the presence of cerium ions was examined in more detail as cerium ions provided the highest inhibitory effect, both to general and pitting corrosion.

AB  - Green corrosion inhibitors, Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate, were tested in NaCl solution with the aim to evaluate their inhibitory effect on 7049 aluminum alloy and to propose a mechanism of their inhibitive action. Corrosion properties of the formed inhibitor layer were analyzed using electrochemical impedance spectroscopy, while the pit formation resistance was analyzed using potentiodynamic polarization tests. Morphology of the formed pits was evaluated by scanning electron microscope/energy-dispersive spectroscopy analysis. It was shown that Ce(III) propionate in NaCl solution has a noticeably higher protective ability than Ce(III) chloride and Ce(III) nitrate. The presence of cerium, propionate anions, and Al–O bonds in the inhibitive layer on the 7049 aluminum alloy surface was confirmed by X-ray photoelectron spectroscopy analysis. This indicates the formation of Ce propionate complexes and bonds via oxygen atoms from carboxylate anions with the metal surface. Density-functional theory methods were used for the geometry optimization of possible Ce propionate complexes as corrosion inhibitors.

AB  - The new environmentally friendly corrosion inhibitor Ce-citrate was analyzed in 0.05 M NaCl solution on the AISI 4130 steel. For comparison, corrosion inhibitor Ce-chloride is tested in the same concentration as Ce-citrate (0.3 mM). Inhibitor efficiencies were determined by applying electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The results of electrochemical measurements, the contact angle measurements, as well as the surface appearance of the specimens after the immersion in the inhibitive NaCl solution for 96 h confirmed that the new environmentally friendly inhibitor (Ce-citrate) has a significantly higher protective ability than the Ce-chloride. The protective ability of Ce-citrate increases over time, according to the proposed mechanism of its action. In the inhibitive layer formed in NaCl solution containing Ce-citrate, XPS analysis revealed the presence of cerium in oxidation states CeIII and CeIV, citrate anions (carboxyl O–C═O group as well as C–OH and C–C and C–H bonds), oxide, hydroxide, and oxyhydroxide of iron (mainly FeOOH and Fe2O3). The mechanism of inhibitory action of Ce-citrate was proposed and analyzed in detail.

AB  - The corrosion behaviour of high-strength AA7075 aluminium alloy in NaCl solution, without and in the presence of environmentally friendly corrosion inhibitors (Ce-chloride and Ce-citrate) in low concentrations (  lt 0.5 mM), was analysed. The degree of precipitation of the solid solution of AA7075 alloy was determined by measuring the electrical conductivity, while the surface morphology and appearance of intermetallic compounds before and after corrosion testing were analysed by SEM/EDS method. The general corrosion resistance of the tested alloy in NaCl solution and the degree of the inhibitory effect of the corrosion inhibitors were determined on the basis of electrochemical impedance spectroscopy and polarization measurements, while resistance to pit formation on the bases of E-pit. AA7075 alloy showed high resistance to general corrosion in the presence of both tested inhibitors, while resistance to pit formation was significantly higher in the presence of Ce-citrate (concentration 0.5 mM). Also, Ce-citrate present in NaCl solution at lower concentrations provides satisfactory resistance of AA7075 alloy to general and pitting corrosion. A mechanism of protective action of Ce-citrate inhibitor has been proposed.

AB  - In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures were confirmed by FTIR, NMR and Elemental Analysis. It was shown that cerium was present in two oxidation states, CeIII and CeIV, when the mixture was analyzed, while there was only a CeIV oxidation state in the cerium-cysteine complex. The mechanisms of inhibitory action of the joint effect of CeCl3 and cysteine vs. their complex were proposed and analyzed in more detail.

AB  - The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings 
were electrodeposited with constant current density on steel, from chloride solution, without any commercial additives. The 
Zn−Mn alloy coatings that show high corrosion resistance, may be used in future as an alternative to cadmium coatings. 
However, the pure Zn and Zn alloy coatings are characterized with poor mechanical properties. Therefore, in this work the 
alumina particles were incorporated into the Zn-Mn matrix, and the hardness and corrosion resistance of the obtained 
composite coatings were tested. The mechanical and ultrasound agitation were used to achieve good dispersion of plating 
solution and homogeneous co-deposition of second phase. The goal was to examine the effect of the agitation type in bath, 
on the attributes of the deposited composite coatings. The incorporation of Al2O3 particles was enhanced when the 
mechanical agitation of the solution was applied. However, in case that this agitation method was used, the agglomeration of 
the alumina particles occurred. In contrast, when an ultrasonic agitation of the plating solution was applied, the uniform 
distribution of the alumina particles could be achieved. The presence of particles in the matrix, along with applied 
ultrasound, resulted in grain refinement and homogeneous microstructure. The Al2O3 nanoparticles incorporated in Zn-Mn 
alloy matrix, resulted in a significant increment in the indentation hardness and a modest increase in the coating corrosion 
resistance. However, the coating hardness increased with alumina addition, only in case when an ultrasonic agitation of the 
electrodeposition solution was used.

AB  - The cytotoxicity of amorphous calcium phosphate (ACP) and chitosan lactate (ChOL) multifunctional and hybrid composite coatings on MRC-5 human lung fibroblast cell line was elucidated. ACP/TiO2 and ACP/TiO2/ /ChOL were deposited onto Ti by a novel in situ anodization/anaphoretic process at constant voltage. Cytotoxicity tests showed that there was no significant decrease in the survival of healthy MRC-5 cells exposed to composite samples without chitosan lactate, while there was an increase in the number of viable cells in the sample containing ChOL. These findings show that there was improved cell proliferation, differentiation and cell viability in the ChOL-containing sample, which makes ACP/TiO2/ChOL coating a good candidate for applications in medicine and stomatology.

AB  - In its pure form, aluminum is easy to process and has a high level of corrosion resistance. However, due to its low strength the possibility of application of pure aluminum is reduced. When alloyed, aluminum alloys are widely used material in construction, different industries, airspace and military. Commercial 7000 series aluminum alloys have zinc as the main alloying element, followed by magnesium. This 7000 aluminum series offers a very high strength when heat-treated, which comes from its composition. The life time of these alloys is reduced due to corrosion damage. It is known that corrosion directly or indirectly affects materials, human health and safety, and it causes global economic and environmental problem. The use of inhibitors in corrosion protection is the simplest, most economical and most efficient approach that is routinely used to ‘reduce’ this problem in industry. The most widely used inorganic inhibitors, such as chromates, are not safe, causing health and safety problems due to their toxicity. Organic compounds have increased interest of the scientific community as potential inhibitors in exchange for the most commonly used. The aim of this study was to investigate new green, eco-friendly inhibitors from the group of amino acid and their combination with lanthanides. For the purposes of this investigation, cerium-cysteine complex was synthesized and analyzed by Fourier-Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM / EDS), Potentiostatic Electrochemical Impedance Spectroscopy (PEIS) and Linear Sweep Voltammetry (LSV) analyses. SEM/EDS was used for morphological analysis and to determine the composition of the aluminum alloy on which the electrochemical tests have been performed. Electrochemical measurements (PEIS, LSV) were erformed in order to test the inhibitory efficacy in 0.1M NaCl at room temperature. Different concentrations of cysteine and Ce-cysteine complex were examined to optimize the process. The adsorption of the inhibitor follows the Langmuir isotherm, and based on the electrochemical results and calculated thermodynamic potential (Gibbs free energy) it can be concluded that both cysteine and cerium-cysteine complex are mixed type of inhibitors. It can be concluded that both cysteine and Ce-cysteine complex inhibitors satisfactory inhibition effect on aluminum alloy corrosion.

AB  - The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition of intermetallic particles was evaluated by a Scanning Electron Microscope, equipped for Energy Dispersive Spectroscopy measurements, while the presence of cerium and type of functional groups in inhibitors surface layers were analyzed by X-ray Photoelectron Spectroscopy and Fourier-Transform Infrared Spectroscopy, respectively. Inhibitor efficiencies were tested by applying electrochemical techniques such as Electrochemical Impedance Spectroscopy and Linear Sweep Voltammetry. Ce-propionate showed a greater inhibitory effect than all other tested corrosion inhibitors. The inhibitory effect decreases in the following order: Ce-propionate > Ce-acetate > Ce-formate > Ce-chloride. Propionate anions have a higher water contact angle and also a longer aliphatic side chain than acetate and formate anions. The mechanism of inhibitory action of Ce-propionate and other tested corrosion inhibitors has been proposed.

AB  - In this study, the corrosion inhibitory activity of symmetrical bis(imino)pyridine (BIP-16) was tested by the Linear Polarization Resistance (LPR) and Electrochemical Impendence Spectroscopy (EIS) methods on zinc and iron. The investigation was carried out in a neutral and acidic medium of 0.5 M NaCI solution. The temperature-dependent (25-45 °C) inhibitory efficacy of BIP-16 on iron and zinc was tested in an acidic medium (pH 3). Under the same conditions, the time dependence of BIP-16 up to 72 h was examined . Moreover, a synergistic effect of BIP-16 with cerium acetate was also examined in time and temperature (25-45 °C) dependence on zinc (pH 7) and iron (pH 3) in 0.5 M NaCI solution at optimal concentrations. The inhibition efficiency of BIP-16 declined with time on both zinc and iron indicating physisorption. Also, kinetic and thermodynamic parameters of this process were calculated. To gain deeper insights into the inhibitory mechanism of tested compounds, DFT calculations were performed.

AB  - Corrosion, although a natural process, presents a costly problem with the possibly dangerous
outcome. Mild steel, which is an alloy used in many industrial applications, manifests poor
corrosion resistance when in contact with corrosive environments and even more so in presence
of chloride ions. This is a particularly important problem in a variety of industrial applications
related to oil and gas processing such as pipeline cleaning pipeline/acid descaling, and oil well
acidizing, where the use of mineral acids (commonly hydrochloric acid) is necessary for
achieving satisfying productivity levels. The most practical method to combat the corrosion issue
is the use of corrosion inhibitors. Organic inhibitors with functional groups such as –OH, –
COOH, NH2, etc, when added in small concentrations to a corrosive solution, can lower the
corrosion rate very efficiently, especially in acidic media. Being that they are also inexpensive,
these organic inhibitors are successfully used for corrosion prevention. A great variety of
organic inhibitors has opened a door to environmentally friendly corrosion inhibition. One of
the environmentally friendly organic compounds are amino acids. They are non-toxic
biomolecules completely soluble in aqueous media and are produced with high purity and at low
cost which makes them a great candidate for a safe corrosion inhibitor. The application of amino
acids and their derivatives against corrosion of iron and its alloys has been investigated so far.
Amino acid based corrosion inhibitor was synthesized by condensing formaldehyde, glyoxal, and
β-alanine, and characterized using FTIR and NMR spectroscopic methods. Imidazolium
zwitterion has been investigated as a corrosion inhibitor on mild steel in 1 M HCl solution using
electrochemical methods: electrochemical impedance (EIS) and linear polarization resistance
(LPR). Different concentrations of inhibitor were used to find the best efficiency. This compound
gave a maximum inhibition efficiency of 74.3 % at 10.7 ppm. The adsorption of inhibitor on mild
steel surface followed the Langmuir adsorption isotherm. Furthermore, electrochemical
measurement results demonstrated that inhibitors act as mixed-type inhibitors (anodic and
cathodic).

AB  - The influence of the microstructure of X5CrNi18-10 stainless steel welded joint on its resistance to general, pitting, and intergranular corrosion was analyzed. The structure of weld metal, heat affected zone (HAZ) and base metal before and after electrochemical testing was analyzed using SEM/EDS. The influence of the roughness level of the welded joint on its resistance to the mentioned types of corrosion was also examined. Although the degree of sensitization of HAZ was significantly lower than the limit value, HAZ showed a noticeably greater tendency to general and pitting corrosion than weld metal and base metal. Polishing has been shown to improve significantly the corrosion resistance of HAZ than in other parts of a welded joint.

AB  - The influence of microstructure and surface roughness of the X5CrNi18-10 austenitic stainless steel-welded joint on resistance to uniform, pitting, and intergranular corrosion, as well as on the stability of the passive film, was evaluated. The microstructure was revealed by optical microscopy and scanning electron microscopy, whereas surface topography and roughness levels were determined by atomic force microscopy. Corrosion characteristics were obtained by the electrochemical potentiokinetic reactivation method with double loop, electrochemical impedance spectroscopy method, as well as by potentiodynamic measurements. The degree of sensitization of heat-affected zone (HAZ) was significantly lower than the threshold value required for the occurrence of intergranular corrosion. However, HAZ showed a significantly greater tendency to pitting and uniform corrosion compared to weld metal and base metal. No effect of roughness levels (RMS from 3.6 to 54 nm) on the pitting potential value of the welded joint was observed (unlike in HAZ). The polished surface shows significantly higher corrosion resistance than the grinded surface. Generally, polishing improved corrosion resistance, especially in HAZ, which is very important because HAZ is a critical place for the occurrence of pitting and other types of corrosion.

AB  - Mushrooms are widely investigated and recognized as perspective materials for the removal
of various pollutants from wastewater effluents. In this study, mosaic puffball Handkea
utriformis was tested as a new biodegradable, but relatively stable material for Cd2+
adsorption from aqueous mediums. The fruiting body of Handkea utriformis goes through the
process of autodigestion, during which their inside – gleba is turned into a powdery, sporebearing mass, and the lower portion of the fruiting body – subgleba, into a dark, dry, spongy
mass. The impurities and spores present on the surface of the subgleba can be removed in a
simple process of purification with acidic and alkaline solutions. The purification decreases
the hydrophobicity of the surface of this material, and therefore increases the number of
surface functionalities, knowing that subgleba consists of sugars, proteins and polymeric
pigments (melanins). The subgleba purified with 0.1M HCl and 0.1M NaOH (Sp) was used
for the removal of Cd2+ from the aqueous solution. The efficiency of the material for
adsorption of Cd2+ was investigated in a batch system under the constant initial concentration
of adsorbate and pH and different concentrations of the adsorbent. Composition and surface
morphology were characterized by using FT-IR spectroscopy, SEM and EDX analysis.
Concentrations of Cd2+, before and after adsorption, were determined by using Atomic
Absorption Spectroscopy (AAS). The Langmuir and Freundlich isotherm models, as well as
kinetic models, were evaluated to correlate experimental data. The results showed that kinetic
data were well fitted by a pseudo-second-order model. Isotherms studies revealed that the
best fit was achieved with the Langmuir isotherm model with a maximum adsorption capacity
of 15.2, 19.1 and 25.0 mg g-1 at 25, 35 and 45ºC, respectively.

abstract = "Mushrooms are widely investigated and recognized as perspective materials for the removal
of various pollutants from wastewater effluents. In this study, mosaic puffball Handkea
utriformis was tested as a new biodegradable, but relatively stable material for Cd2+
adsorption from aqueous mediums. The fruiting body of Handkea utriformis goes through the
process of autodigestion, during which their inside – gleba is turned into a powdery, sporebearing mass, and the lower portion of the fruiting body – subgleba, into a dark, dry, spongy
mass. The impurities and spores present on the surface of the subgleba can be removed in a
simple process of purification with acidic and alkaline solutions. The purification decreases
the hydrophobicity of the surface of this material, and therefore increases the number of
surface functionalities, knowing that subgleba consists of sugars, proteins and polymeric
pigments (melanins). The subgleba purified with 0.1M HCl and 0.1M NaOH (Sp) was used
for the removal of Cd2+ from the aqueous solution. The efficiency of the material for
adsorption of Cd2+ was investigated in a batch system under the constant initial concentration
of adsorbate and pH and different concentrations of the adsorbent. Composition and surface
morphology were characterized by using FT-IR spectroscopy, SEM and EDX analysis.
Concentrations of Cd2+, before and after adsorption, were determined by using Atomic
Absorption Spectroscopy (AAS). The Langmuir and Freundlich isotherm models, as well as
kinetic models, were evaluated to correlate experimental data. The results showed that kinetic
data were well fitted by a pseudo-second-order model. Isotherms studies revealed that the
best fit was achieved with the Langmuir isotherm model with a maximum adsorption capacity
of 15.2, 19.1 and 25.0 mg g-1 at 25, 35 and 45ºC, respectively.",

maleinske kiseline na bio-osnovi iz 5-hidroksimetilfurfurala (HMF) i levulinske kiseline; proizvodi sa
termalnim hidroksilnim grupama, zasnovani su na otpadnom PET-u i karboksil, hidroksil i vinil termalnom
fosfatnom estru kraft lignina; (II) sinteza bio-UPR smola koristeći proizvode iz prve faze i vinil derivate iz
HMF-a i kraft lignina kao vezujućeg agensa za UPR smole; (III) homogenizacija UPR smola sa aditivima
