Supercritical impregnation of cellulose acetate with thymol
(Elsevier Science Bv, Amsterdam, 2015)
Present work was aimed to investigate supercritical solvent impregnation of thymol into cellulose acetate in order to explore the possibility of developing a new functionalized solvent-free material with antimicrobial ...
Suitability of TiO2 nanoparticles and prolate nanospheroids for laser desorption/ionization mass spectrometric characterization of bipyridine-containing complexes
(Elsevier Science Bv, Amsterdam, 2015)
Nanostructured materials as substrates for surface-assisted laser desorption and ionization time-of-flight mass spectrometry have two main advantages such as small number of signals in the low mass range and salt tolerance. ...
Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
Biocompatible and degradable scaffolds based on 2-hydroxyethyl methacrylate, gelatin and poly(beta amino ester) crosslinkers
(Elsevier Sci Ltd, Oxford, 2018)
Gelatin hydrogels have great potential in regenerative medicine but their weak mechanical properties are a major drawback for the load-bearing applications, such as scaffolds for tissue engineering. To overcome this ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
Introduction of cleaner production in the tank farm of the Pancevo Oil Refinery, Serbia
(Elsevier Sci Ltd, Oxford, 2010)
This work studies the introduction of cleaner production (UP) in the tank farm of the Pancevo Oil Refinery. From 2003 to 2008, substantial investments in storage technology and equipment were made in order to minimize the ...
The use of nanoclay in preparation of epoxy anticorrosive coatings
(Elsevier Science Sa, Lausanne, 2014)
Epoxy/clay nanocomposites (NC) have become a very interesting topic among researchers in the past two decades because nanoclays have a positive effect on the mechanical, thermal and especially barrier and anticorrosive ...
Core-shell superparamagnetic iron oxide nanoparticle (SPION) clusters: TEM micrograph analysis, particle design and shape analysis
(Elsevier, 2016)
For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell ...
Approach to laminar phenomena occurring on external and internal surfaces of solid specimens
(Kluwer Academic Publishers, 2000)
This article presents a general mathematical model for describing the laminar transport phenomena during homogeneous/heterogeneous appearances in the neighborhood of external and internal surfaces of small solid specimens. ...
