Synthetic Active Liquid Crystals Powered by Acoustic Waves

Advanced Materials, EarlyView.
A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

Quantitative analysis of attack-fault trees via Markov decision processes [PDF]

arXiv
Adequate risk assessment of safety critical systems needs to take both safety and security into account, as well as their interaction. A prominent methodology for modeling safety and security are attack-fault trees (AFTs), which combine the well-established fault tree and attack tree methodologies for safety and security, respectively. AFTs can be used

A Body Conformal Ultrasound Receiver for Efficient and Stable Wireless Power Transfer in Deep Percutaneous Charging

Advanced Materials, EarlyView.
Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency

Efficient Autonomous Dew Water Harvesting by Laser Micropatterning: Superhydrophilic and High Emissivity Robust Grooved Metallic Surfaces Enabling Filmwise Condensation and Radiative Cooling

Advanced Materials, EarlyView.
Laser micropatterning is presented as a promising technology in the search for autonomous dew water harvesting materials. Laser‐grooved metallic surfaces achieve simultaneously high infrared emissivity and superhydrophilicity, which gives them self‐cooling properties under atmospheric radiative deficit and the ability to condense water in an efficient ...
