Studies of the Iranian Medieval Ceramics Surface Modified by Pulsed Tea CO2 and Nd:YAG Lasers
(Elsevier Ltd and Techna Group S.r.l., 2015)
This paper presents the results of the morphological and chemical changes on the surface of an Iranian ceramics sample irradiated by a Transversely Excited Atmospheric (TEA) CO2 and an Nd:YAG laser. The sample originates ...
Mesoporous 12-tungstophosphoric acid/activated bentonite catalysts for oxidation of 2-propanol
(Elsevier, 2011)
In the present study, the effect of 12-tungstophosphoric acid (HPW) immobilisation on the catalytic activity of H(3)PW(12)O(40)/mesoporous acid-activated bentonite catalysts (AAB) was investigated. The catalysts were ...
Proteomic analysis of food borne pathogens following the mode of action of the disinfectants based on pyridoxal oxime derivatives
(Elsevier, 2017)
A comprehensive proteomic analysis of food borne pathogens after treatment with disinfectants based on ammonium salts of pyridinium oxime was performed. Changes in proteomes of the Gram-positive bacterium Bacillus subtilis ...
The DsbA signal peptide-mediated secretion of a highly efficient raw-starch-digesting, recombinant alpha-amylase from Bacillus licheniformis ATCC 9945a
(Elsevier Sci Ltd, Oxford, 2013)
In this study, a new approach for extracellular production of recombinant alpha-amylase in Escherichia coli was investigated. A gene encoding a highly efficient raw-starch-digesting alpha-amylase from Bacillus licheniformis ...
Palladium-copper bimetallic surfaces as electrocatalysts for the ethanol oxidation in an alkaline medium
(Elsevier, 2023)
Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C), and ...
Perfluorinated compounds in sediment samples from the wastewater canal of Pancevo (Serbia) industrial area
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Perfluoroalkyl sulfonates (PFSAs) and perfluoroalkyl carboxylates (PFCAs) were analyzed in sediment samples from the wastewater canal draining the industrial complex of Pancevo, Serbia (oil refinery, petrochemical plant, ...
Transformation and synthesis of humic substances during bioremediation of petroleum hydrocarbons
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this paper was to investigate whether changes in the quantity and structure of humic acids (HA) occur during bioremediation of waste mazute (heavy residual fuel oil). The effects of humification on the structure ...
Influence of film formation on light-trapping properties of randomly textured silicon thin-film solar cells
(The Japan Society of Applied Physics, 2014)
The influence of film formation on light-trapping properties of silicon thin-film solar cells prepared on randomly textured substrates was studied. Realistic interface morphologies were calculated with a three-dimensional ...
Improvement of the epoxy coating properties by incorporation of polyaniline surface treated TiO2 nanoparticles previously modified with vitamin B6
(Elsevier Science Sa, Lausanne, 2016)
Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of ...
Blue-light-driven photoactivity of L-cysteine-modified graphene quantum dots and their antibacterial effects
(Elsevier, 2024)
The widespread abuse of traditional antibiotics has led to a global rise in antibiotic-resistant bacteria, which give in return unprecedented health risks. Therefore, there is a large and urgent need for the development ...
