Advanced Functional Materials, EarlyView.Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Advanced Functional Materials, EarlyView.Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Development of a Wöhler-like approach to quantify the Ti(CxNy) coatings durability under oscillating sliding conditions [PDF]
, 2005 The selection of a proper material for the particular engineering application is a complex problem, as different materials offer unique properties and it is not possible to gather all useful characteristics in a single one. Hence, employment of different

Programmable Entanglement of Granular Mechanical Metamaterials
Advanced Functional Materials, EarlyView.This paper introduces entangled granular metamaterials—clusters of complex grains whose interlocking drives emergent, tunable properties. Here, we identify geometric features that enable entanglement and quantify them via disentanglement dynamics. We demonstrate robotic handling where magnetically controlled grains achieve robust collective picking and

Model predictive control for current balancing in a four-phase buck converter [PDF]
, 2016 Multiphase buck topology offers smaller ripple current and lower component ratings. This, however, compromises unbalanced output current between each phase of an inductor which leads to over-current and inductor saturation issues.

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin
Advanced Healthcare Materials, EarlyView.Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.
