Ecofriendly Upcycling of Poly(vinyl chloride) Waste Plastics into Precious Metal Adsorbents

open access: yesAdvanced Science, EarlyView.
Poly(vinyl chloride) waste plastics are simply transformed into high‐performance precious metal (PM) adsorbents via a facile and green hydrazine‐functionalization process. The resultant adsorbent effectively and selectively recovers PM from real‐world leachates via its combined chemisorption and reduction mechanisms.

Advanced Atomic Layer Modulation Based Highly Homogeneous PtRu Precious Metals Alloy Thin Films

open access: yesAdvanced Science, EarlyView.
A unique idea of atomic layer modulation (ALM) that sequentially pulses DDAP and Ru(TMM)(CO)3, two precursors with one counter reactant O2 to produce ALM‐PtRu homogeneous PtRu bimetallic alloys at the nanoscale. It smartly adjusted precursor pulse time and temperature, ensuring stoichiometric and compositionally atomistic controlled highly ...

Tailoring Hydrogenation to Enhance Defect Suppression and Charge Transport in Hydrogenated Amorphous Silicon for Flexible Photodetectors

open access: yesAdvanced Science, EarlyView.
Hydregen content was tailored during ultra‐low‐temperature plasma‐enhanced chemical vaper deposition (PECVD) to deposit hydrogenated amorphous silicon (a ‐ Si:H) films, and the effect of the hydrogen dilution ratio on defect suppression was analyzed.

Dynamic Bonds Reinforced Polyamide Elastomer for Biomedical Orthosis

open access: yesAdvanced Science, EarlyView.
A dynamic bonds (DBs) reinforced shape memory polyamide elastomer is developed using reactive extrusion. Dynamic covalent networks enhance interlayer adhesion in 4D‐printed objects by utilizing the combined effects of multiple DBs, reducing mechanical anisotropy and improving the mechanical and shape memory properties.
