Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Effective Sliding Motions of Vibration‐Induced Emission Stoppers in Mechanically Interlocked Molecules as Artificial Muscle Tougheners and In Situ Molecular Shuttling Sensors for Self‐Healable Mechano‐Fluorescent Polyurethane Organogels

open access: yesAdvanced Functional Materials, EarlyView.
The self‐healable ratiometric mechano‐fluorescent polyurethane (PU) organogel is constructed by incorporating a minor amount (ca. 1.5 wt.%) of the unconventional daisy chain rotaxane (as an artificial molecular muscle toughener) with specific sliding motions and ratiometric emission behaviors into the PU skeleton, which reveals the progressed intrinsic

Flood vulnerability assessment in the Ili River Basin based on the comprehensive symmetric Kullback–Leibler distance

open access: yesScientific Reports
In vulnerability assessments, accurately determining the indicator weights is essential to ensure the results’ precision and reliability. This paper proposes an optimized comprehensive symmetric Kullback–Leibler (K–L) distance weighting method, in which ...

Overview of national plan for NHS blood and transplant and hospitals to address blood shortage in the United Kingdom (Series 1): Emergency management framework

open access: yesZhongguo shuxue zazhi
As a vital resource, blood directly impacts the life and health of patients and the continuity of medical care. Given that it can only be obtained through voluntary donations from blood donors, its supply is susceptible to shortages due to various ...

Current practices in managing acutely disturbed patients at three hospitals in Rio de Janeiro-Brazil: a prevalence study [PDF]

open access: yes, 2002
The medical management of aggressive and violent behaviour is a critical situation for which there is little evidence. In order to prepare for a randomised trial, due to start in the psychiatric emergency rooms of Rio de Janeiro in 2001, a survey of ...

Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.

Dynamic Mechanical Properties of Sandstone Weaken Under Multiple Impacts Based on SHPB Experiments

open access: yesGeofluids
Due to multiple dynamic disturbances caused by mining activities, the internal fractures in the surrounding rock of the roadway continue to expand, resulting in the continuous weakening of the mechanical properties of the sandstone.

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response

open access: yesAdvanced Functional Materials, EarlyView.
This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...
