Eliminating dissolution of platinum-based electrocatalysts at the atomic scale
(Nature Publishing Group, 2020)
A remaining challenge for deployment of proton-exchange membrane fuel cells is the
limited durability of Pt-nanoscale materials that operate at high voltages during the
cathodic oxygen reduction reaction. In this work, ...
Dynamic stability of active sites in hydr(oxy)oxides for the oxygen evolution reaction
(Springer Science and Business Media LLC, 2020)
The poor activity and stability of electrode materials for the oxygen evolution reaction (OER) are the main bottlenecks in the water splitting reaction for H2 production. Here, by studying activity
stability trends for ...
The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier, 2020)
Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x =0.00 – 0.10) ...
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 ...
Hepatic oxidative stress and neurotoxicity in Pelophylax kl. esculentus frogs: Influence of long-term exposure to a cyanobacterial bloom
(Elsevier, 2021)
Although the long-term exposure of aquatic organisms to cyanobacterial blooms is a regular occurrence in the environment, the prooxidant and neurotoxic effects of such conditions are still insufficiently investigated in ...
Optimization of microbial fuel cell operation using Danube River sediment
(Elsevier, 2020)
One of the main global focuses of mankind today is the required switch to new energy sources. Generating energy from waste is one of the potential solutions that can be achieved using microbial fuel cells (MFCs). Microorganisms, ...
Role of aromatic amino acids in amyloid self-assembly
(Elsevier, 2020)
Amyloids are proteins of a cross-β structure found as deposits in several diseases and also in normal tissues (nails, spider net, silk). Aromatic amino acids are frequently found in amyloid deposits. Although they are not ...
Production of levan by Bacillus licheniformis NS032 in sugar beet molasses-based medium
(Elsevier, 2019)
The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100-140 g/L of total sugars) with the addition ...
Biodegradation of the aromatic fraction from petroleum diesel fuel by Oerskovia sp. followed by comprehensive GC x GC-TOF MS
(Elsevier, 2019)
Polycyclic aromatic hydrocarbons (PAHs) from petroleum and fossil fuels are one of the most dominant pollutants in the environment. Since aromatic fraction from petroleum diesel fuel is mainly composed of PAHs, it is ...
Structural and electrochemical properties of the Li2FeP2O7/C composite prepared using soluble methylcellulose
(Elsevier, 2019)
A new method involving the homogeneous dispersion of precursor compounds inside a methylcellulose matrix is used for the synthesis of a composite powder of Li 2 FeP 2 O 7 and carbon. The properties of carbon-containing and ...
