Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramicsh
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Surface characterization of mesoporous carbon cryogel and its application in arsenic (III) adsorption from aqueous solutions
(Elsevier, 2015)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Experimental and numerical research on the failure of railway vehicles coupling links
(Engineering Failure Analysis, 2021)
Two modes of failure are analysed for coupling links, the mechanical connections that transmit traction forces between vehicles along the length of a train. Coupling links are designed to withstand the dynamic loads in ...
Spatial distribution, radiological risk assessment and positive matrix factorization of gamma-emitting radionuclides in the sediment of the Boka Kotorska Bay
(Marine Pollution Bulletin, 2021)
Surface sediment from the Boka Kotorska Bay (Adriatic Sea) was analyzed for the content of technogenic cesium (137Cs) and naturally occurring (40K, 226Ra, 232Th, 238U) radionuclides. The activity concentrations of the ...
Valorization of corn stover and molasses for enzyme synthesis, lignocellulosic hydrolysis and bioethanol production by Hymenobacter sp. CKS3
(Environmental Technology & Innovation, 2021)
During the last few decades, energy demand is increasing rapidly. Concerning this, the use of renewables - lignocellulose biomass, for bioethanol production, as an efficient alternative to replacing fossil fuels, is highly ...
Halochromic cellulose textile obtained via dyeing with biocolorant isolated from Streptomyces sp. strain NP4
(Cellulose, 2021)
Halochromic (pH-responsive) material was obtained by dyeing functionalized viscose fabric with a crude extract from Streptomyces sp. strain NP4. The functionalization of the fabric before dyeing was performed to make ...
Selected Aromatic Plants Extracts as an Antimicrobial and Antioxidant Finish for Cellulose Fabric- Direct Impregnation Method
(Fibers and Polymers, 2021)
Six ethanolic extracts, obtained from anise, fennel, lavender, sage, mint, white horehound and their mixture were directly applied onto cellulose (viscose) fabric to impart antimicrobial and antioxidant functionality for ...
Supramolecular Perspective of Coordination Effects on Fluorine Interactions
(Crystal Growth & Design, 2021)
Coordination effects have been considered through the most common interactions in the crystal structures of fluoro compounds (C-H/F and F/F interactions). The supramolecular profile of these effects is based on quantum-chemical ...
The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier Sci Ltd, Oxford, 2020)
Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x = 0.00 - 0.10) ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
