Recovery of tungsten trioxide from waste diamond core drilling crowns by nitric acid leaching
(International Journal of Refractory Metals & Hard Materials, 2021)
A cost-effective and simple hydrometallurgy procedure for recycling the diamond core drilling crowns by nitric acid leaching, followed by the sodium hydroxide leaching, has been developed. The effect of temperature, nitric ...
Viscoelasticity and cell jamming state transition
(European Physical Journal Plus, 2021)
Although collective cell migration (CCM) is a highly coordinated migratory mode, perturbations in the form of jamming state transitions and vice versa often occur even in 2D. These perturbations are involved in various ...
Plant Extracts Rich in Polyphenols as Potent Modulators in the Growth of Probiotic and Pathogenic Intestinal Microorganisms
(Frontiers in Nutrition, 2021)
Medicinal plants and their extracts contain substantial quantities of polyphenols. As metabolically active plant metabolites, polyphenols are food components with a wide range of biological activities. Given their poor ...
Valorization of corn stover and molasses for enzyme synthesis, lignocellulosic hydrolysis and bioethanol production by Hymenobacter sp. CKS3
(Environmental Technology & Innovation, 2021)
During the last few decades, energy demand is increasing rapidly. Concerning this, the use of renewables - lignocellulose biomass, for bioethanol production, as an efficient alternative to replacing fossil fuels, is highly ...
Fabrication of bacterial cellulose-based wound dressings with improved performance by impregnation with alginate
(Elsevier, Amsterdam, 2020)
Bacterial cellulose (BC) hydrogels are among the most efficient materials already being used for the treatment of complex wounds. The moist environment provided by the BC dressing is a key feature assuring efficient wound ...
Optimization of forced periodic operations in milli-scale fixed bed reactor for Fischer-Tropsch synthesis
(Elsevier, Amsterdam, 2020)
One-dimensional pseudo-homogenous dynamic reactor model, incorporating detailed Fischer-Tropsch kinetics, was applied in a theoretical analysis of forced periodic operations. A milli-scale fixed-bed reactor was analyzed, ...
Removal of Estrone, 17 beta-Estradiol, and 17 alpha-Ethinylestradiol from Water by Adsorption onto Chemically Modified Activated Carbon Cloths
(Korean Fiber Soc, Seoul, 2020)
This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the ...
Advances in Thermochemical Synthesis and Characterization of the Prepared Copper/Alumina Nanocomposites
(MDPI, Basel, 2020)
This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al(2)O(3)system with 1-2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion ...
Aerogel Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 catalysts for hydrodesulphurisation of dibenzothiophene and 4,6-dimethyldibenzothiophene
(Catalysis Today, 2021)
Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 aerogel catalysts were synthesized using sol-gel method and super-critical drying in excess solvent, and investigated in the hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and ...
A Strategy to Revalue a Wood Waste for Simultaneous Cadmium Removal and Wastewater Disinfection
(Adsorption Science & Technology, 2021)
In this investigation, the possibility of wood waste (hardwoods such as oaks' and alternatives' staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All ...
