3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.

Transcript Identification Using Arrayed Hydrogels With TrapFISH

open access: yesAdvanced Materials Technologies, EarlyView.
TrapFISH is a novel method for high‐throughput single‐cell transcriptomics. It embeds cells in hyaluronic acid hydrogel beads and uses probe hybridization to quantify custom gene panels. By arraying hydrogels in microfluidic devices, cell barcoding is removed, enhancing scalability for studying cellular heterogeneity and rare cell states by targeting ...

Bio‐Inspired Strategy for Radiation‐Based Thermal Management and Utilization

open access: yesAdvanced Science, EarlyView.
Biological organisms have evolved remarkable strategies to manage and exploit thermal radiation. This review explores bio‐inspired systems that mimic these adaptations—such as radiative cooling, thermal regulation, thermal insulation, water harvesting, infrared camouflage, and infrared detection—and highlights their application in thermal management ...

A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication

open access: yesAdvanced Science, EarlyView.
A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.

Do Jet-Driven Shocks ionize the Narrow Line Regions of Seyfert Galaxies? [PDF]

open access: yes, 1999
We consider a model in which the narrow line regions (NLRs) of Seyfert galaxies are photoionized ``in situ'' by fast (300 -- 1,000 km/s), radiative shock waves driven into the interstellar medium of the galaxy by radio jets from the active nucleus.
