Environmental Behaviors of (E)-Pyriminobac-methyl in Agricultural Soils
(E)-Pyriminobac-methyl (EPM), a pyrimidine benzoic acid esters herbicide, has a high potential as weedicide; nevertheless, its environmental behaviors are still not well understood. In this study,
Spatio-temporal photolysis rate profiles of UV254 irradiated toluene
The volatile organic compound (VOC) toluene is irradiated with a 254 nm UV source. The studied sample (1 mL) of toluene is equipped in a sealed quartz cuvette and inserted in one of the Michelson
Assessing and measuring the active site density of PGM-free ORR catalysts
Fuel cells are already employed in commercial transportation even though their price is still too high to enable widespread production. A viable and promising pathway taken to lower this price is the
Atomically dispersed iron sites with a nitrogen–carbon coating as highly active and durable oxygen reduction catalysts for fuel cells
Nitrogen-coordinated single atom iron sites (FeN 4 ) embedded in carbon (Fe–N–C) are the most active platinum group metal-free oxygen reduction catalysts for proton-exchange membrane fuel cells.
Quantifying the electrochemical active site density of precious metal-free catalysts in situ in fuel cells
Advances in the development of precious-group metal-free (PGM-free) catalysts for the oxygen reduction reaction (ORR) in fuel cell cathodes have produced active catalysts that reduce the performance
Materials Engineering toward Durable Electrocatalysts for Proton Exchange Membrane Fuel Cells
Proton exchange membrane fuel cells (PEMFCs) have penetrated many commercial markets, especially in the automotive market as Toyota has launched the first commercially mass‐produced fuel cell
Non-PGM Electrocatalysts for PEM Fuel Cells: A DFT Study on the Effects of Fluorination of FeNx-Doped and N-Doped Carbon Catalysts
Fluorination is considered as a means of reducing the degradation of Fe/N/C, a highly active FeNx-doped disorganized carbon catalyst for the oxygen reduction reaction (ORR) in PEM fuel cells. Our

Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for
In Situ Surface-Enhanced Raman Spectroscopy to Investigate Polyyne Formation During Pulsed Laser Ablation in Liquid
The synthesis of polyynes during their formation by pulsed laser ablation in liquid (i.e., acetonitrile) has been analyzed by in situ surface-enhanced Raman spectroscopy (SERS). A polyethylene
