3D Printing of Highly Electrically Conductive Zinc for Sustainable Electronics Applications
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A 3D printable zinc ink system with active zinc particles in a shellac matrix is demonstrated. The results show high conductivity, stable performance of printed structures under varying humidity conditions, and promising application in disposable water‐activated batteries. This technology combining digital material assembly, reliable operation, and non‐

Advanced Materials Technologies, EarlyView.An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Advanced Photonics Research, EarlyView.This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.

Cortical Dynamics of Visual Motion Perception: Short-Range and Long Range Apparent Motion [PDF]
, 1991 This article describes further evidence for a new neural network theory of biological motion perception that is called a Motion Boundary Contour System. This theory clarifies why parallel streams Vl-> V2 and Vl-> MT exist for static form and motion form ...

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits
Advanced Photonics Research, EarlyView.A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...

Shunting passenger trains: getting ready for departure [PDF]
, 2008 In this paper we consider the problem of shunting train units on a railway station. Train units arrive at and depart from the station according to a given train schedule and in between the units may have to be stored at the station.

Advanced Science, EarlyView.A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.
