TiO2/APTES cross-linked to carboxylic graphene based impedimetric glucose biosensor
(Elsevier, 2020)
Herein, we proposed a novel approach and state-of-the-art technology for the improvement of the materials and
enzyme immobilization at the electrode surface and construction of impedimetric glucose biosensor. We ...
How flexible is the water molecule structure? Analysis of crystal structures and the potential energy surface
(Royal Society of Chemistry, 2020)
Water molecules from crystal structures archived in the CSD show a relatively large range both in the bond angle and bond lengths. High level ab initio calculations at the CCSD(T)/CBS level predicted a possibility for ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
A new acetylcholinesterase allosteric site responsible for binding voluminous negatively charged molecules – the role in the mechanism of AChE inhibition
(Elsevier, 2020)
Acetylcholinesterase (AChE) inhibitors are important in the treatment of neurodegenerative diseases. Two inhibitors,
12-tungstosilicic acid (WSiA) and 12-tungstophosphoric acid (WPA), which have polyoxometalate
(POM) ...
Microstructure and biopharmaceutical performances of curcumin-loaded low-energy nanoemulsions containing eucalyptol and pinene: Terpenes’ role overcome penetration enhancement effect?
(Elsevier, 2020)
he objective of this work was to develop low-energy nanoemulsions for enhanced dermal delivery of curcumin, using monoterpene compounds eucalyptol (EUC) and pinene (PIN) as chemical penetration enhancers. Spontaneous ...
A novel nonenzymatic hydrogen peroxide amperometric sensor based on AgNp@GNR nanocomposites modified screen-printed carbon electrode
(Elsevier, 2020)
A nonenzymatic hydrogen-peroxide sensor was developed by utilization of silver nanoparticles and graphene
nanoribbons. The mentioned composite was inflicted on a screen-printed carbon electrode which provides disposable ...
Microstructure and cavitation erosion performance of nickel-Inconel 718 composite coatings produced with cold spray
(Elsevier, 2020)
The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the ...
Integration of dry-column flash chromatography with NMR and FTIR metabolomics to reveal cytotoxic metabolites from Amphoricarpos autariatus
(Elsevier, 2020)
Metabolomics generate a profile of small molecules from plant extracts, which could be directly responsible for bioactivity effects. Using dry-column flash chromatography enabled a rapid and inexpensive method for the very ...
Phenol and Toluene Stacking Interactions, including Interactions at Large Horizontal Displacements. Study of Crystal Structures and Calculation of Potential Energy Surfaces
(American Chemical Society (ACS), 2020)
The study of crystal structures from the Cambridge Structural Database (CSD) shows that most of p-phenol/p-phenol and toluene/toluene stacking interactions are at large horizontal displacements (offsets) as well as ...
Intermolecular interactions of cis-3-hexen-1-ol or 1-hexanol with n-hexane: Thermodynamic study, FT-IR analysis and quantum chemical calculations
(Elsevier, 2020)
Thermodynamic properties (density, viscosity, refractive index and speed of sound) of pure substances cis-3-hexen-1-ol, 1-hexanol and n-hexane and their binary systems cis-3-hexen-1-ol + n-hexane and 1-hexanol + n-hexane ...
