Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
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 ...

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. ...
Microwave-assisted extraction for the recovery of antioxidants from waste Equisetum arvense
(Elsevier, Amsterdam, 2014)
Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content ...
Isopiestic determination of the osmotic and activity coefficients of the {yK(2)SO(4) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2014)
The molality-based osmotic coefficients of aqueous mixtures of K2SO4 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method, at K2SO4 ionic strength fractions y = (0.21008, 0.39887, 0.60657, ...
Impact of ultrasound on egg white proteins as a pretreatment for functional hydrolysates production
(Springer, New York, 2014)
The objective of this study was to investigate the effects of different ultrasound pretreatment on enzymatic hydrolysis of egg white proteins (EWPs) by Alcalase as well as evaluating some functional and antioxidant properties ...
Adventitious organogenesis via intermediate callus formation in representatives of Prunus, Pyrus and Rubus genera
(Ars Docendi, Bucharest, 2014)
The paper presents evaluation of the influence of 30 combinations of plant growth regulators (PGRs) on induction of adventitious organogenesis from leaves of in vitro propagated shoots in 5 genotypes: sour cherry 'Cacanski ...
Recovery of precious (Au, Ag, Pd, Pt) and other Metals by e-scrap processing
(Bulgarian Chemical Communications, 2014)
The professional paper is a brief report of an investigation results to be adopted into production. In fact it is a resume of a study on the idea of e-scrap processing and metal production in Mining and Metalurgy Institute ...
pH-Sensitive Hydrogels Based on (Meth)Acrylates and Itaconic Acid
(Polymer Soc Korea, Seoul, 2014)
Novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA), itaconic acid (IA) and different poly (alkylene glycol) (meth)acrylates (PAGM) (P(HEMA/IA/PAGM)) were synthesized. We investigated the influence of different ...
