Crystal growth of la(2)srb(10)o(19)from undercooled melt
(Springer, Dordrecht, 2020)
The crystal growth rate of La(2)SrB(10)O(19)in an undercooled melt of stoichiometric composition was studied. The crystallization of the bulk samples was performed in a single-stage regime under isothermal conditions at ...
Multipurpose Nonwoven Viscose/Polypropylene Fabrics: Effect of Fabric Characteristics and Humidity Conditions on the Volume Electrical Resistivity and Dielectric Loss Tangent
(Korean Fiber Society, 2020)
In this work, the volume electrical resistivity and dielectric loss tangent of viscose/polypropylene multipurpose nonwoven fabrics were examined. According to the obtained results, the changes in the volume electrical ...
Ecological Risk Assessment of Heavy Metals in the Soil at a Former Painting Industry Facility
(Frontiers Media Sa, Lausanne, 2020)
Soil samples from the site of the former largest paint and varnish factory in ex-Yugoslavia were analyzed for arsenic and eight heavy metals (Pb, Cd, Zn, Cr, Ni, Cu, Fe, and Hg). Several additional soil properties (pH, ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Substituent Effects on the Patterns of Intermolecular Interactions of 3-Alkyl and 3-Cycloalkyl Derivatives of Phenytoin: A Crystallographic and Quantum-Chemical Study
(American Chemical Society (ACS), 2019)
A series of five derivatives of the anticonvulsant drug phenytoin was synthesized, and their crystal structures were determined. The relationship between the molecular and crystal structure of the investigated compounds ...
Catalytic activity of SnO2- and SO4 /SnO2-containing clinoptilolite in the esterification of levulinic acid
(Elsevier B.V., 2019)
Catalysts based on natural zeolite - clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content ...
Isopiestic determination of the osmotic and activity coefficients of {yK(2)HPO(4) + (1-y)KH2PO4}(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2020)
Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 ...
Assessment of Leaching Characteristics of Solidified Products Containing Secondary Alkaline Lead Slag
(MDPI, Basel, 2019)
Reuse of waste is one of the main principles of sustainable development and circular economy. Secondary alkaline lead slag is a hazardous waste generated in the recycling process of lead-acid batteries that may be suitable ...
Synthesis, characterization and SAR studies of bis(imino)pyridines as antioxidants, acetylcholinesterase inhibitors and antimicrobial agents
(Academic Press Inc Elsevier Science, San Diego, 2020)
In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase ...
Bioprocessing of agro-industrial residues into lactic acid and probiotic enriched livestock feed
(Wiley, Hoboken, 2019)
BACKGROUND Growing challenges of resource depletion, food security and environmental protection are putting stress on the development of biorefinery processes for bioprocessing of residues from food and agro-industry into ...
