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. ...
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 ...
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 ...

Mathematical modeling of silver release from antimicrobial nanocomposite Ag/alginate microbeads
(Wiley-Blackwell, Hoboken, 2014)
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. ...
Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
Novel alginate based nanocomposite hydrogels with incorporated silver nanoparticles
(Springer, Dordrecht, 2012)
Alginate colloid solution containing electrochemically synthesized silver nanoparticles (AgNPs) was investigated regarding the nanoparticle stabilization and possibilities for production of alginate based nanocomposite ...
