Solid-State Synthesis of Highly Dispersed Nitrogen-Coordinated Single Iron Atom Electrocatalysts for Proton Exchange Membrane Fuel Cells.

Nano Lett 2021 Apr 19. Epub 2021 Apr 19.

Department of Chemical and Biological Engineering, The Hong Kong University of Science and Technology, Clear Water Bay, Kowloon, Hong Kong, P.R. China.

Fe-N-C with atomically dispersed Fe single atoms is the most promising candidate to replace platinum for the oxygen reduction reaction (ORR) in fuel cells. However, the conventional synthesis procedures require quantities solvents and metal precursors, sluggish adsorption process, and tedious washing, resulting in limited metal doping and uneconomical for large-scale production. For the first time, FeO is adopted as the Fe precursor to derive abundant single Fe atoms dispersed on carbon surfaces. Read More

Delaying Broccoli Floret Yellowing by Phytosulfokine α Application During Cold Storage.

Front Nutr 2021 1;8:609217. Epub 2021 Apr 1.

Department of Genetic and Plant Breeding, Faculty of Agriculture and Natural Resources, Imam Khomeini International University, Qazvin, Iran.

During postharvest life, broccoli suffers from floret yellowing confining its economic and nutritional value. The objective of the present study was to explore the mechanisms employed by phytosulfokine α (PSKα) at 150 nM for delaying floret yellowing in broccoli during storage at 4°C for 28 days. Our results showed that the higher endogenous accumulation of hydrogen sulfide (HS) resulting from the higher gene expression and activities of l-cysteine desulfhydrase () and d-cysteine desulfhydrase () in broccoli floret treated with 150 nM PSKα may serve as an endogenous signaling molecule for delaying senescence.
