Polysulfide Crosslinked Cotton by Reaction of Chlorodeoxycellulose with Ethylenediamine Hydrosulfide

open access: yes, 1976
Cotton fabrics with polysulfide crosslinks were prepared by reacting chlorodeoxycellulose with ethylenediamine hydrosulfide in ethylenediamine at 54–100°C. The polysulfide fabrics had good wet wrinkle resistance (280°) and strength retention (above 65%).

ZIF‐67 In Situ Grown PAN Spun Membrane Gel Electrolyte for Sodium‐Sulfur Batteries

open access: yesCarbon Energy, EarlyView.
This illustration shows the fabrication process of a solid‐state electrolyte for sodium‐sulfur (Na‐S) batteries. First, a polyacrylonitrile (PAN) fibrous membrane is prepared. Next, ZIF‐67 is grown in situ on the PAN membrane to form PAN@ZIF‐67. Subsequently, polyethylene oxide (PEO) is introduced into PAN@ZIF‐67 to obtain the composite electrolyte PEO/

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

open access: yesCarbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.
