Electrospun PAN Membrane Loaded with AgInP2Se6 Nanosheets for Triboelectric Energy Harvesting

Small, EarlyView.
Exfoliated AgInP2Se6 nanosheets are incorporated into a polyacrylonitrile (PAN) polymer matrix by electrospinning and applied for the first time in a triboelectric nanogenerator (TENG). The hybrid membrane delivers strong electrical output and exhibits reversible humidity sensitivity, responding rapidly to changes in relative humidity.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.
