Assessment of leaching characteristics of solidified products containing secondary alkaline lead slag
(MDPI, 2019)
Reuse of waste is one of the main principles of sustainable development and circular economy. Secondary alkaline lead slag is a hazardous waste generated in the recycling process of lead-acid batteries that may be suitable ...
Voltammetric protocol for reliable determination of a platelet aggregation inhibitor dipyridamole on a bare miniaturized boron-doped diamond electrochemical sensor
(Electrochemical Society Inc., 2019)
In present paper, a miniaturized boron-doped diamond electrode (BDDE) was for the first time used as a reliable electrochemical sensor within the novel voltammetric protocol for the rapid and simple determination of ...
Influence of methionine residue position on oxidative stability of glucose oxidase from Aspergillus niger
(Elsevier, 2019)
Glucose oxidase (GOx) is a promising candidate for construction of implantable miniature biofuel cells and biosensors for continuous glucose monitoring. The main drawback that limits current application of GOx in these ...
Stacking Interactions of Resonance-Assisted Hydrogen-Bridged Rings. A Systematic Study of Crystal Structures and Quantum-Chemical Calculations
(American Chemical Society, 2019)
Stacking interactions of resonance-assisted hydrogen-bridged rings are quite common, as 44% of their crystal structures show mutually parallel contacts. High-level quantum-chemical calculations by the CCSD(T)/CBS method ...
Synthesis of tribological WS 2 powder from WO 3 prepared by ultrasonic spray pyrolysis (USP)
(MDPI, 2019)
This paper describes the synthesis of tungsten disulfide (WS 2 ) powder by the sulfurization of tungsten trioxide (WO 3 ) particles in the presence of additive potassium carbonate (K 2 CO 3 ) in nitrogen (N 2 ) atmosphere, ...
Advances in Thermochemical Synthesis and Characterization of the Prepared Copper/Alumina Nanocomposites
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al2O3 system with 1–2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion beam ...
Zinc Deficiency, Plasma Fatty Acid Profile and Desaturase Activities in Hemodialysis Patients: Is Supplementation Necessary?
(Frontiers Media, 2021)
Background: Desaturation and elongation are critical processes in endogenous metabolic fatty acid pathways. Zinc (Zn) is a cofactor for desaturases and elongases enzymes. There is limited evidence regarding the relationships ...
Stacking interactions of resonance-assisted hydrogen-bridged rings and C6-aromatic rings
(Royal Society of Chemistry, 2020)
Stacking interactions between six-membered resonance-assisted hydrogen-bridged (RAHB) rings and C6-aromatic rings were systematically studied by analyzing crystal structures in the Cambridge Structural Database (CSD). The ...
Assessment of trace metal alterations in the blood, cerebrospinal fluid and tissue samples of patients with malignant brain tumors
(Nature Research, 2020)
The pathogenesis of malignant brain tumors (MBTs) should be better understood due to the evident association between prolonged exposure to metals and increased risk of MBTs. The present research aimed to find trace metals ...
Microbial levan and pullulan as potential protective agents for reducing adverse effects of copper on Daphnia magna and Vibrio fischeri
(Elsevier, 2019)
Microbial polysaccharides, due to their unique physiochemical properties, have found application in the food industry, cosmetics, pharmacy and medicine. In the environment, microbes can use polysaccharides to alleviate the ...
