Electrochemical Chlorine Shuttle from PVC Waste to Vinyl Ether Acceptors for the Synthesis of Biodegradable Polyester Precursors

Advanced Materials, EarlyView.
A sustainable, paired electrolysis method is presented to recycle PVC, one of the world's most used polymer materials. Our innovative and robust process transfers chlorine from waste PVC and produces valuable precursors for biodegradable polyester materials.

Photoaccumulation of Long‐Lived Reactive Electrons in a Microporous Ti(IV) Oxocluster‐Based Metal–Organic Framework for Light and Dark Photocatalysis

Advanced Materials, EarlyView.
The microporous Ti12 oxocluster‐based MOF MIP‐177(Ti)‐LT exhibits effective charge separation and long‐lived photogenerated electrons persisting for hours, as revealed by spectroscopy. These electrons cause reversible color changes and enable dark H2 evolution and water splitting, demonstrating remarkable electron storage and redox capability ...

Wet‐Chemical Etching of Silicon Wafer Surfaces Using Aqueous HF‐HBrO3 and HF‐HBrO3‐Br2 Solutions

Advanced Materials Interfaces, EarlyView.
Aqueous mixtures of HF and HBrO3 are reported as a new NOx‐free etching systems for monocrystalline silicon wafers. Silicon is polished with etching rates up to 10 µm min−1 at room temperature. The addition of Br2 leads to anisotropic etching, thus texturing monocrystalline silicon wafer surfaces with upright pyramids.

A Degradable Device for Sustainable Capillary Blood Sampling

Advanced Materials Technologies, EarlyView.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
