Advanced oxidation processes in the treatment of corn stalks
(Elsevier B.V., 2023)
The depletion of fossil fuel reserves and severe environmental damage, resulting in climate change and global warming lead to a necessary shift to alternative renewable resources. Lignocellulose is a valuable feedstock for ...
Environmentally benign few-bilayer intumescent nanocoating for flame retardant enzyme/plasma modified polyester fabric
(Elsevier Ltd, 2023)
The flammability of polyester textiles remains a significant challenge that must be overcome to allow their use in a variety of clothing and upholstery applications. In this work, water-based polyelectrolyte solutions ...
Antimicrobial viscose fabric prepared by treatment in DBD and subsequent deposition of silver and copper ions-Investigation of plasma aging effect
(Elsevier Science Sa, Lausanne, 2013)
In this work, the effect of dielectric barrier discharge (DBD) in ambient air on preparation of antimicrobial viscose fabric was studied. DBD plasma treatment was applied under constant discharge power and different exposure ...
Characterization analysis of Poplar fluff pyrolysis products. Multi-component kinetic study
(Elsevier Sci Ltd, Oxford, 2019)
This paper describes the pyrolysis of Poplar fluff (from Populus alba) using on-line apparatus, and carbonization process at 850 degrees C using the fixed bed reactor. Characteristics of pyrolysis products were examined. ...
The influence of the surface nanostructured modification on the corrosion resistance of the ultrafine-grained Ti-13Nb-13Zr alloy in artificial saliva
(Elsevier, Amsterdam, 2019)
On the surface of the ultrafine-grained Ti-13Nb-13Zr alloy and the coarse-grained Ti-13Nb-13Zr alloy nanotubular oxide layers were formed by electrochemical anodization in the 1 M H3PO4 + NaF electrolyte in order to evaluate ...
Experimental study of insulating properties and behaviour of thermal barrier coating systems in thermo cyclic conditions
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to improve the resistance of turbo jet engine parts exposed to high temperatures and overheating and sudden changes in temperature. For this purpose, three thermal barrier coating (TBC) systems ...
Development of Coated Electrodes with Solid Wire and Flux-Cored Alloyed Wire for Microalloyed Steel Welding
(MDPI, Basel, 2020)
In this paper, we will present our investigation of the quality of J55 microalloyed steel welds that were formed by a basic flux-cored wire electrodes that were of appropriate quality and alloyed with Ni and Mo. Based on ...
Tensile and Corrosion Properties of Anodized Ultrafine-Grained Ti-13Nb-13Zr Biomedical Alloy Obtained by High-Pressure Torsion
(Korean Inst Metals Materials, Seoul, 2021)
Severe plastic deformation (SPD) is a popular group of techniques applied to achieve the nanostructuring of the metallic biomaterials and improvement of their mechanical characteristics. One of the most commonly used SPD ...
Highly efficient enzymatic acetylation of flavonoids: Development of solvent-free process and kinetic evaluation
(Elsevier Science Bv, Amsterdam, 2017)
Solubility and stability of flavonoid glycosides, valuable natural constituents of cosmetics and pharmaceuticals, could be improved by lipase-catalyzed acylation. Focus of this study was on development of eco-friendly ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
