Advanced Materials Technologies, EarlyView.Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

Advanced Materials Technologies, EarlyView.This work examines how contact–semiconductor overlap influences volumetric capacitance extraction in organic electrochemical transistors as device dimensions shrink. It shows that neglecting overlap leads to systematic, geometry‐driven errors in capacitance values.

Position and velocity recovery from independent ultrasonic beacons [PDF]
, 2006 In this paper we present a study on how to estimate the position of a mobile receiver using ultrasonic beacons fixed in the environment. Unlike traditional approaches, the ultrasonic beacons are independent, and positioning is performed by measuring the ...

Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups
Advanced Materials Technologies, EarlyView.Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...
