A novel chitosan/tripolyphosphate/L-lysine conjugates for latent fingerprints detection and enhancement
(Journal of Forensic Sciences, 2021)
Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various ...
Structural diversity of manganese(II) complexes containing 2,2 '-dipyridylamine and benzenedicarboxylates. Conformational analysis of tere-, iso- and phthalate ions: An experimental and quantum chemical approach
(Elsevier S.A., 2016)
Four novel manganese(II) complexes with 2,2'-dipyridylamine (dipya) and various benzenedicarboxylate, BDC, ligands as anions of phthalic (pht), isophthalic (ipht) and terephthalic (tpht) acids were hydrothermally synthesized, ...
Amino-modified kraft lignin microspheres as a support for enzyme immobilization
(Royal Society of Chemistry, 2020)
In this research, it has been demonstrated that amino-modified microspheres (A-LMS) based on bio-waste derived material, such as kraft lignin, have good prospects in usage as a support for enzyme immobilization, since ...
High-performance laminate material based on polyurethane and epoxide reinforced by silica particles from rice husk used for intelligent pedestrian crossings
(Springer Science and Business Media Deutschland GmbH, 2021)
Intelligent pedestrian crossings were made with the aim to increase pedestrian safety at poorly lit locations. New technologies include the design of polymer materials that have high performance by optimizing properties ...
Preparation and Characterization of Silver-Loaded Hemp Fibers with Antimicrobial Activity
(Korean Fiber Soc, Seoul, 2014)
The objective of this research was to impart antimicrobial properties to hemp fibers by incorporation of silver ions in hemp fibers by chemisorption. Sorption properties of hemp fibers were improved by non-selective oxidation ...
Solvent effects on structural changes in self-healing epoxy composites
(Elsevier Science Sa, Lausanne, 2020)
Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and ...
Preparation of floating polymer-valsartan delivery systems using supercritical CO2
(Journal of Polymer Research, 2021)
This study investigates pharmaceutical polymers (Soluplus((R)), HPMCAS, and Eudragit((R)) E100) and supercritical CO2-assisted process for preparation of floating valsartan delivery systems. Tested process (at pressure of ...
Advantage of use of activated flux-cored wire instead of solid wire with the mag welding process from the mechanical properties aspect
(Croatian Metallurgical Soc, Zagreb, 2013)
The objective of this paper is the analysis and evaluation of the quality of the new flux-cored wire designed for the MAG welding process that was developed and produced using special laboratory equipment. Experimental ...
Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
Self-Assembly and Biorecognition of a Spirohydantoin Derived from alpha-Tetralone: Interplay between Chirality and Intermolecular Interactions
(Wiley-VCH Verlag, 2020)
A racemic spirohydantoin derivative with two aromatic substituents, a tetralin and a 4-methoxybenzyl unit, was synthesized and its crystal structure was determined. To define the relationship between molecular stereochemistry ...
