Advanced Materials Technologies, EarlyView.Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Foreign experience in determining the status of refugees and internally displaced persons
Aspekti Publìčnogo Upravlìnnâ, 2017 This article explores the problem of determining the status of refugees and internally displaced persons in the countries of the European Union. Due to the increasing problem of internal involuntary displacement in other countries an understanding of the

Advanced Materials Technologies, EarlyView.Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface
Advanced Materials Technologies, EarlyView.Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...
