Architected Soft Actuators for Artificial Musculoskeletal Systems

Advanced Materials, EarlyView.
An architected soft actuator uses a servo motor and a combination of 3D printed architected elastomers to extend and contract. The actuator exhibits high actuation stroke, force output, and power density for constructing bioinspired artificial musculoskeletal systems.

Nanometer Resolution Structure‐Emission Correlation of Individual Quantum Emitters via Enhanced Cathodoluminescence in Twisted Hexagonal Boron Nitride

Advanced Materials, EarlyView.
Nanometer‐resolution mapping of individual quantum emitters in hexagonal boron nitride is achieved, allowing us to identify the 440 nm blue emitter as a substituted vertical carbon dimer. Leveraging this atomic‐level insight, the deterministic creation of isolated single 440 nm blue emitters is demonstrated through localized electron beam irradiation ...

Room‐Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle–Liquid Crystal System

Advanced Materials, EarlyView.
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Sugars in Antimicrobial Polymers – The Impact of Sugar‐Lectin Binding in Membrane Interaction of Cationic Glycopolymers

Advanced Materials Interfaces, EarlyView.
Photo‐iniferter polymerization is used to create antimicrobial polymers which are decorated with sugar units by either copolymerization of glycomonomers or post‐polymerization functionalization. Although a selectivity based on lectin binding can not be observed, the presence of sugar leads to improved bioactivity based on the presence of neutral ...

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

Advanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...
