Amplifier‐Based Programmable Metasurface for Bidirectional Full Polarization Enhancement

open access: yesSmall Structures
Electromagnetic waves emitted by a transmitter in practical scenarios are often degraded by obstacles along the transmission path, polarization mismatch, and distance to the receiver, which significantly limits the quality of wireless communication.

A Complementary Hole‐Transport Layer of PTAA and SAM on FTO Substrate for p‐i‐n Structured Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
The complementary roles of Poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine (PTAA) and self‐assembly monolayer (SAM) in a composite hole transport layer for rough fluorine‐doped tin oxide substrates are demonstrated, with PTAA preferentially depositing in the valleys and SAM occupying the peaks, resulting in improved surface potential uniformity ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Additively Manufactured Diamond for Energy Scavenging and Wireless Power Transfer in Implantable Devices

open access: yesAdvanced Functional Materials, EarlyView.
Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...
