Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

Advanced Functional Materials, EarlyView.
Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...

Chemistry of PCBs and PBBs [PDF]

Environmental Health Perspectives, 1978
A recent book by Hutzinger et al. (1) reviews the chemistry of chlorinated biphenyls through the end of 1973. This wide-ranging review also includes discussions of metabolism and determination of chlorinated biphenyls. The present report reviews areas of chlorobiphenyl and bromobiphenyl chemistry held to be pertinent to the Subcommittee's concern for ...

Multiwavelength Implantable Oximeter for Wireless Monitoring of Tissue Oxygenation in the Presence of Blood Volume Changes

Advanced Healthcare Materials, EarlyView.
This study presents an implantable, wireless, battery‐free oximeter that can continuously monitor physiologically consistent regional tissue oxygenation under dynamic changes of blood volume. This is achieved through multiwavelength photoplethysmography and validated both via Monte Carlo simulations and in vivo rat studies. Different stress events were

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–
