Achieving Photo‐Activated Circularly Polarized Room Temperature Phosphorescence from Natural Biopolymers

Advanced Science, EarlyView.
This bio‐based chiral luminescent system exhibit photo‐activated CPRTP by anchoring arylboronic acids to hydroxypropyl cellulose (HPC) matrix. Notably, by controlling the drying kinetics, dynamic switchable CPRTP with opposite handedness can be obtained due to a balance of photonic bandgap (PBG) effect and chirality transfer effect induced by the HPC ...

Enhanced Energy Harvesting Performance of Biodegradable Polylactic Acid/3D Anodic Aluminum Oxide Composite Triboelectric Nanogenerators

Advanced Electronic Materials, EarlyView.
Polylactic acid (PLA) embedded in 3D anodic aluminum oxide (3D‐AAO) yields triboelectric nanogenerators (TENGs) with ɛeff = 5.1, delivering 20V and 108µW both per cm2. These agglomeration‐resistant, compostable/biocompatible devices retain 95% output after 104 cycles, enabling robust self‐powered Internet of Things (IoT) sensing.

Peroxidase application reduces microcrystalline cellulose recalcitrance towards cellulase hydrolysis in model cellulose substrates and rooibos biomass

Carbohydrate Polymer Technologies and Applications
We have identified a HRP enzyme with microcrystalline cellulose activity, which has not yet been explored. The current study investigated the effect of HRP pretreatment on the microcrystalline cellulose substrates, Avicel and filter paper.
