Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Simultaneous selenium and sulfur speciation analysis in cultivated Pleurotus pulmonarius mushroom
(Elsevier Sci Ltd, Oxford, 2019)
Selenium (Se) and sulfur (S) speciation analysis in edible and medicinal Se enriched P. pulmonarius extracts was performed. Mycelium, colonized substrate, and fruiting bodies at different harvesting times were analyzed ...

(2016 International Conference on Electronics and Information Technology, EIT 2016, 2016)
The paper gives a brief overview of computer controlled thermogravimetric analysis system. The system consists of a personal computer, software, data acquisition card and interface for the provision of the necessary ...
Stability of gold complex based on mercaptotriazole in acid and neutral media
(Bulgarian Academy of Sciences, 2018)
Stability of the gold complex based on mercaptotriazole in two acid electrolytes with different pH values and in a neutral medium was investigated in this work. Investigation was performed by visual monitoring and ...
The Antimicrobial Activities of Silver Nanoparticles Synthesized from Medicinal Mushrooms
(Begell House Inc, Danbury, 2020)
Crude polysaccharide extracts derived from Agaricus bisporus (A), A. brasiliensis (B), and Phellinus linteus (P) were used for the synthesis of silver nanoparticles (AgNPs, labeled AAgNP, BAgNP, PAgNP, respectively) UV and ...
Microhardness of decorative gold coatings obtained from gold complex based on mercaptotriazole: Comparison with cyanide
(Carl Hanser Verlag, Munich, 2016)
The aim of this work was to investigate the effects of current density, temperature, pH and concentration of ethyl-hexilsulfonate additive on the microhardness of electrochemically deposited gold decorative coatings obtained ...
Antifungal activity of Ag:hydroxyapatite thin films synthesized by pulsed laser deposition on Ti and Ti modified by TiO2 nanotubes substrates
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HA) is a widely used biomaterial for implant thin films, largely recognized for its excellent capability to chemically bond to hard tissue inducing the osteogenesis without immune response from human tissues. ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
