beta-Amylase production from packaging-industry wastewater using a novel strain Paenibacillus chitinolyticus CKS 1
(Royal Society of Chemistry, 2015)
Transport packaging factories generate a large amount of wastewater that contains residuals of starch glue. These residuals could be used as substrates for microorganism growth and enzyme production. In this study, ...
Keratin-polyethylene oxide bio-nanocomposites reinforced with ultrasonically functionalized graphene
(Royal Society of Chemistry, 2015)
Polyethylene oxide (PEO) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene in PEO aqueous solution. The feasible sonication protocol of PEO degradation and graphene functionalization enabled ...
Methacrylic Acid Based Polymer Networks with a High Content of Unfunctionalized Nanosilica: Particle Distribution, Swelling, and Rheological Properties
(Amer Chemical Soc, Washington, 2015)
The poor stability and tendency to agglomerate of unfunctionalized nano-SiO2 in the presence of ionic species presents a challenge for preparing poly(methacrylic acid)/nano-SiO2 nanocomposite (NC) hydrogels with desired ...
Influence of fluid-mechanical parameters on volumetric mass transfer coefficient in a spout-fluid bed with a draft tube
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In order to apply a spout-fluid bed reactor with a draft tube for the nitrification process of wastewater treatment, the influence of fluid-mechanical parameters on volumetric mass transfer coefficient was analyzed. ...
Impregnation of corona modified polypropylene non-woven material with thymol in supercritical carbon dioxide for antimicrobial application
(Elsevier Science Bv, Amsterdam, 2015)
This study discusses the possibility of impregnation of polypropylene (PP) and corona modified PP non-woven material with thymol in supercritical solvent in order to fabricate eco-friendly antimicrobial textile material. ...
Dual responsive antibacterial Ag-poly(N-isopropylacrylamide/itaconic acid) hydrogel nanocomposites synthesized by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation ...
Artificial neural network modelling of biological oxygen demand in rivers at the national level with input selection based on Monte Carlo simulations
(Springer Heidelberg, Heidelberg, 2015)
Biological oxygen demand (BOD) is the most significant water quality parameter and indicates water pollution with respect to the present biodegradable organic matter content. European countries are therefore obliged to ...
Analogy between momentum and heat transfer in liquid-solid fluidized beds
(Elsevier Science Bv, Amsterdam, 2015)
Wall-to-bed heat transfer in particulate fluidized beds of spherical particles was studied. Experiments were performed using spherical glass particles of 0.80-2.98 mm in diameter with water in a 25.4 mm I.D. copper tube ...
Diversity in extinction laws of Type Ia supernovae measured between 0.2 and 2 mu m
(Oxford Univ Press, Oxford, 2015)
We present ultraviolet (UV) observations of six nearby Type Ia supernovae (SNe Ia) obtained with the Hubble Space Telescope, three of which were also observed in the near-IR (NIR) with Wide-Field Camera 3. UV observations ...
Hydrocarbon selectivity models for iron-based Fischer-Tropsch catalyst
(Elsevier, Amsterdam, 2015)
Two kinetic models of Fischer-Tropsch product selectivity have been developed based on reaction networks from the literature. The models were fitted to experimental data obtained using commercial iron-based catalyst in a ...
