Improvement of the epoxy coating properties by incorporation of polyaniline surface treated TiO2 nanoparticles previously modified with vitamin B6
(Elsevier, 2016)
Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of ...
Fractal approach to BaTiO3-ceramics micro-impedances
(Elsevier, 2015)
A new approach, based on fractal geometry and correlation between microstructure-nanostructure and rare-earth properties and other additives doped BaTiO3-ceramics and electronics properties, is applied. The grain contacts ...
2D and 3D silver-based coordination polymers with thiomorpholine-4-carbonitrile and piperazine-1,4-dicarbonitrile: structure, intermolecular interactions, photocatalysis, and thermal behavior
(Royal Society of Chemistry (RSC), 2021)
Four silver-based coordination polymers, {[Ag(L1)2]NO3}∞ (1), {[Ag(L1)2]ClO4}∞ (2), {[Ag(L2)2]NO3·H2O}∞ (3) and {[Ag(L2)2]ClO4}∞ (4), were synthesized using the thiomorpholine-4-carbonitrile (L1) and piperazine-1,4-dicarbonitrile ...
Fabrication, in vitro degradation and the release behaviours of poly(DL-lactide-co-glycolide) nanospheres containing ascorbic acid
(Colloids and Surfaces B: Biointerfaces, 2007)
Ascorbic acid (vitamin Q is essential for preserving optimal health and is used by the body for many purposes. The problem is that ascorbic acid easily decomposes into biologically inactive compounds making its use very ...
Processing and characterization of UHMWPE composite fibres with alumina particles in poly(ethylene-vinyl acetate) matrix
(SAGE, 2018)
Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different sizes and morphologies ...
Microstructure and mechanical properties of disperse Ni-Co alloys electrodeposited on Cu substrates
(Elsevier, 2010)
The nickel and cobalt disperse alloy deposits of five different compositions were obtained by electrodeposition on Cu substrates in the galvanostatic regime from an ammonium sulfate-chloride solution. The effect of cathodic ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
Ceramic materials and energy - Extended Coble’s model and fractal nature
(Elsevier, 2019)
The new frontiers open different directions within the higher and deeper knowledge structure using unemployed nano sizes domains. The BaTiO3 and other ceramic materials have fractal configuration nature based on three ...
Optimizing storage conditions to prevent cold denaturation of trypsin for sequencing and to prolong its shelf life
(Elsevier, 2016)
Trypsin is a serine protease with widespread applications, including protein sequencing and trypsin mass fingerprinting. In the present study, the storage of trypsin in acidic conditions significantly affected the recovery ...
Discrete temperature values in the sintering process as a BaTiO3-ceramics properties parameter
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, we develop the new physical-mathematical time scale approach-model applied to BaTiO3-ceramics. At the beginning, a time scale is defined to be an arbitrary closed subset of the real numbers R, with the ...
