Bacterial diversity in typical abandoned multi-contaminated nonferrous metal(loid) tailings during natural attenuation
(Elsevier, 2019)
Abandoned nonferrous metal(loid) tailings sites are anthropogenic, and represent unique and extreme ecological niches for microbial communities. Tailings contain elevated and toxic content of metal(loid)s that had negative ...
Enantioselective Organocatalytic Enamine C−H Oxidation/Diels‐ Alder Reaction
(Wiley, 2019)
α,β‐unsaturated aldehydes have been traditionally used in LUMO lowering asymmetric aminocatalysis (iminium catalysis), while the use of saturated aldehydes as substrates in this type of catalysis has been elusive, until ...

Binding of metal ions and water molecules to nucleic acid bases: The influence of water molecule coordination to a metal ion on water–nucleic acid base hydrogen bonds
(International Union of Crystallography, 2019)
The interactions of nucleic acid bases with non-coordinated and coordinated water molecules were studied by analyzing data in the Protein Data Bank (PDB) and by quantum chemical calculations. The analysis of the data in ...
Antibacterial and Antibiofilm Activity of Flavonoid and Saponin Derivatives from Atriplex tatarica against Pseudomonas aeruginosa
(American Chemical Society (ACS), 2019)
A new flavonoid glucoside derivative, patuletin 3-O-(2-O-feruloyl)-β-D-glucuronopyranosyl-(1→2)-β-Dglucopyranoside, named atriplexin IV (1), and three new triterpenoid saponin derivatives, two sulfonylated, β-Dglucopyran ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn® aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was prepared ...
Novel non-enzymatic glucose sensing material based on pillared clay modified with cobalt
(Elsevier, 2019)
Cobalt oxide supported on pillared clay was synthesized and used as modifier of carbon paste electrode. Cyclic Voltammetry and Impedance Spectroscopy were employed to evaluate the performance of investigated electrode in ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Elsevier, 2019)
Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors ...
Stabilization of apo α-lactalbumin by binding of epigallocatechin-3-gallate: Experimental and molecular dynamics study
(Elsevier, 2019)
α-Lactalbumin (ALA) is a Ca2+-binding protein which constitutes up to 20% of whey protein. At acidic pH, and in the apo-state at elevated temperatures, ALA is the classic 'molten globule' (MG). This study examined ...
Lewis versus Brønsted Acid Activation of a Mn(IV) Catalyst for Alkene Oxidation
(American Chemical Society, 2019)
Lewis acid (LA) activation by coordination to metal oxido species has emerged as a new strategy in catalytic oxidations. Despite the many reports of enhancement of performance in oxidation catalysis, direct evidence for ...
