Fluorination as a Driving Force in Crystal Structures
(Commission on Quantum Crystallography of IUCr, 2020)
The results of the crystallographic analysis in combination with quantum chemical calculations have
shown that fluorination of organic compounds causes an increase in the proton-donating ability and a
decrease in the ...
Implementacija aditivne proizvodnje u Lean koncept / Implementation of additive manufacturing in the lean concept
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu prikazan je značaj aditivne proizvodnje u okviru Lean koncepta. Koncept definiše sedam
vrsta proizvodnog otpada, dok Lean proizvodnja podrazumeva uklanjanje tog otpada. Aditivna proizvodnja
ispunjava sve ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Theoretical Study of σ-hole Bonding between Selenium Atoms in Crystal Structures of Organoselenium Compounds
(Stellenbosch, South Africa : Department of Chemical and Polymer Science at Stellenbosch University, 2020)
Non-covalent interactions involving selenium atoms are of great importance in chemistry and biochemistry due to the prominent role of selenium-containing molecules (like Se-antioxidants and selenoenzymes) in different ...
Impregnation of cellulose acetate with natural bioactive compounds using supercritical carbon dioxide
(Book of abstracts - 7th International Congress of the European Polysaccharide Network of Excellence, 2021)
Porous acetate cellulose (CA) beads were tested as carriers for thymol, eugenol and
carvacrol, natural compounds well known for their biological activity. For this purpose,
selected compounds were impregnated into CA ...
Development of novel labelling system for microplastics
(Oficyna Wydawnicza Politechniki Rzeszowskiej, 2021)
Microplastics are microscopic pieces (<5 mm) of plastic materials that can be found at
every corner of our planet. Two ways of their release into the environment can be discerned: primary and secondary microplastics. While ...
Bioleaching of metals from printed pc motherboard by acidithiobacillus ferrooxidans
(RemTech Europe, 2021)
Electronic waste is the fastest growing waste category. This emphasizes the need for effective electronic waste recycling strategies. Recycling of electronic waste is crucial not only from the viewpoint of waste treatment ...
Improving competitiveness through technological and industrial innovation
(Zrenjanin : Technical Faculty "Mihajlo Pupin", 2021)
The globalization of markets affects how enterprises conduct business. In addition to the challenges of
the globalized market, enterprises have to adapt to changes that the coronavirus pandemic has brought to the
global ...
Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates.
(Belgrade : Academy of Criminalistic and Police Studies, 2020)
Fine-grained nickel coatings were electrodeposited by direct current (dc) regime
onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single
crystal (100)-oriented silicon. These ...
Electrical properties of isothermally sintered cordierite-based ceramics as function of sintering and activation time / Električna svojstva izotermski sinterovane keramike na bazi kordierita kao funkcija vremena sinterovanja i aktivacije
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
