Thermodynamic Properties of Caffeine in Ethylene Glycol at High Pressures and High Temperatures
(USA : American Chemical Society, 2022)
Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of ...
The influence on microorganisms of heavy metals from refiner’s spent desulphurisation catalysts
(Taylor & Francis, 2022)
Refinery wastes generated in conventional crude oil refining processes, or in accidental situations, are complex substrates for treatment and disposal. Petroleum desulphurisation catalysts can also be hazardous refinery ...
The development of a process simulator transport model for RO systems
(Elsevier, 2022)
This paper introduces solute-solvent interactions onto a universal transport modeling approach that has been recently introduced for predicting RO membrane performance. The mathematical modeling framework utilizes chemical ...
Aromaticity study of singlet- and triplet-state corannulene dianion and dication
(John Wiley and Sons Ltd, 2022)
Aromaticity rules in the ground singlet state and the first excited triplet state are exactly opposite, as shown by Baird. Thus, (4n + 2)π electron annulenes are antiaromatic and 4nπ annulenes are aromatic in their triplet ...
Analysis of inhibitory properties of Ce-citrate as a green corrosion inhibitor of low alloy steel in neutral chloride solution
(Wiley, 2022)
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 ...
Inhibitory effect of cysteine and lanthanides on AA7075‐T6 in neutral NaCl solution
(Weinheim, Germany : Wiley‐VCH GmbH., 2022)
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 ...
Revival of Hückel Aromatic (Poly)benzenoid Subunits in Triplet State Polycyclic Aromatic Hydrocarbons by Silicon Substitution
(Wiley, 2022)
By employing density functional theory (DFT)
calculations we show that mono- and disilicon substitution in
polycyclic aromatic hydrocarbons, having two to four
benzene units, quenches their triplet state antiaromaticity ...
Cerium citrate as ecologically friendly corrosion inhibitor for AA7075 alloy
(Wiley, 2022)
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 ...
Silver distribution and binding mode as key determinants of the antimicrobial performance of iron oxide/silver nanocomposites
(Elsevier, 2022)
The emerging threat of bacterial resistance to antibiotics prompts the urgent search for biomaterials for the treatment of infectious disease. Here we report on the synthesis and characterization of a multiphasic nanocomposite ...
Cobalt(II) and magnesium(II) complexes with 1,3-pdta-type of ligands: influence of an alkyl substituent at 1,3-propanediamine chain on the structural and antimicrobial properties of the complex
(Taylor &Francis, 2022)
To investigate how modification in the structure of 1,3-propanediamine chain of 1,3-pdta (1,3-propanediamine-N,N,N′,N′-tetraacetate) ligand affects the structural and biological properties of the corresponding metal ...
