Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

Advanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

The Function of Photocatalytic Performance and Carrier Separation Efficiency Tuned by Doping Content in Homogeneous Photocatalysts

Advanced Science, EarlyView.
A doping model of homogeneous photocatalysts of TiO2 is constructed to directly show the mapping relationship between carrier separation efficiency and photocatalytic performance. TRPL, KPFM, fs‐TAS measurements further quantify the carrier dynamics process. The photocatalytic performance of this series samples is dominated by the optimal conditions of

Robust Controlled Degradation of Enzyme Loaded PCL‐Based Fibrous Scaffolds Toward Scarless Skin Tissue Regeneration

Advanced Science, EarlyView.
A novel biodegradable wound dressing (E‐PCLs) based on polycaprolactone (PCL) and an enzyme complex (RHP‐BCL) is developed using a fiber microfluidic electrospinning technique. The dressing achieves complete degradation within 14 days, eliminates microplastic residues, and promotes scar‐free healing (99% in 21 days).

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

Unlocking Methane Generation via Photo‐Thermal‐Coupled CO2 Hydrogenation by Integrating FeNiCrMnCo Multicomponent Alloy with GaN Nanowires

Advanced Science, EarlyView.
A noble‐metal‐free FeNiCrMnCo multicomponent alloy (MCA) integrated with GaN nanowires achieves efficient photo‐thermal‐coupled CO₂ methanation, delivering a methane production rate of 199 mmol∙g−¹∙h−¹ with 93% selectivity. The system demonstrates exceptional stability and tunable catalytic properties, offering a sustainable pathway for solar‐driven ...
