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

open access: yesAdvanced 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.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

open access: yesAdvanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Polymer Brush‐Based Asymmetric Porous Patch with Excellent Anti‐Bacterial and Anti‐Contamination Properties Enables Infectious Abdominal Wall Defect Repair

open access: yesAdvanced Science, EarlyView.
A zwitterionic asymmetric patch is developed via self‐induced phase separation. The cationic layer exhibits anti‐bacterial efficacy and releases pro‐healing factor, while the zwitterionic hydrogel prevents contamination and visceral adhesion. The strong mechanical interlocking of two layers leads to a high and stable burst pressure tolerance.

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

open access: yesAdvanced 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).

Piezoresistive Effect: A New Concept for Hearing Aids

open access: yesAdvanced Science, EarlyView.
An MXene/PVA sound sensor utilizing piezoresistive effects has been proposed with a detection limit of 60 dB and a frequency response of 20–4000 Hz, which is comparable to the performance of commercial hearing aids. By combining the sensor with machine learning, the accuracy rate of voiceprint recognition of wildlife conservation can reach up to 99 ...
