Advanced Functional Materials, EarlyView.The addition of calcium ions to silk fibroin enhances the hydrogel properties and, when combined with visible light crosslinking, enables compatibility with advanced light‐based fabrication techniques. Calcium ions extend the shelf‐life of silk and facilitate the fabrication of multizonal, multilayered constructs for advanced stimuli‐responsive ...

Underwater Hearing Thresholds [PDF]
The Journal of the Acoustical Society of America, 1956 Underwater hearing thresholds were measured at frequencies of 250, 500, 1000, 2000, and 4000 cps on four Aqualung equipped divers with normal hearing in air. In the frequency range investigated, the minimum audible fields underwater are from 44 to 60 db greater than the minimum audible fields in air, and the shape of the threshold vs frequency curve is

Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction
Advanced Functional Materials, EarlyView.To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

Advanced Functional Materials, EarlyView.Post‐surgical tumor therapy struggles with recurrence and inefficient healing. Anti‐tumor DNA aptamer functionalized gelatin hydrogels, Apt‐GelMA, simultaneously address both issues by suppressing tumor regrowth via targeted tumor cell inhibition and enhancing wound healing through improved cell adhesion and migration. Their biocompatibility, stability,

Advanced Functional Materials, EarlyView.Ultra‐short pulsed laser processing (ULSP) enables scalable, open‐air fabrication of self‐organized, quasi‐periodic micro/nanostructures on copper using 100 µm laser beams, orders of magnitude larger than the resulting surface features. Integrated into ultra‐thin, wick‐free vapor chambers, these laser‐functionalized surfaces dramatically enhance ...
