Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly
Advanced Science, EarlyView.This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

Achievable directive antenna gain measurements and modeling for 60 GHz indoor links
Scientific ReportsHighly directive antennas may be a key component in millimeter wave links to offset their inherently high path losses. In cluttered scenarios such as Non-Line-Of-Sight (NLOS) indoor settings, antenna gain is degraded by the interaction of the channel ...

Integrated Analysis of Line-Of-Sight Stability of Off-Axis Three-Mirror Optical System
PhotonicsAs a space camera works in orbit, the stress rebound caused by gravity inevitably results in the deformation of its optomechanical structure, and the relative position change between different optical components will affect the Line-Of-Sight pointing of ...

Advanced Science, EarlyView.Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Reconstruction of multiple non-line-of-sight objects using back projection based on ellipsoid mode decomposition [PDF]
, 2018 Non-line-of-sight imaging has attracted more attentions for its wide applications.Even though ultrasensitive cameras or detectors with high time-resolution are available, current back-projection methods are still powerless to acquire a satisfying ...

Advanced Science, EarlyView.We present a stimulus‐replicating system combining a tactile sensor with a wearable Peltier thermotactile module and concentric electrotactile electrode. Signals encoding pressure and temperature drive the stimulators to reproduce mechano‐thermal cues on the skin. AlN/PDMS encapsulation and SA/LA PSA ensure mechanical compliance and thermal efficiency.

Advanced Science, EarlyView.Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.
