Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

Advanced Materials Technologies, EarlyView.
The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited

Biodegradable and Edible Milli‐Fluidic Logic Circuits

Advanced Materials Technologies, EarlyView.
Fully biodegradable and edible fluidic circuits are developed using gelatin‐based valves that operate at low pressure. Logic gates, a one‐bit memory, and a ring oscillator are demonstrated, showing that biodegradable materials can perform computation and control.

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

Advanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

Short and Length‐Independent Group Delay Supported by Topological Edge States in Finite‐Size Su–Schrieffer–Heeger Chains

Advanced Materials Technologies, EarlyView.
This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Highly Conductive and Transparent Coatings via Low‐Temperature Hydroiodic Acid Vapor Treatment of Oxo‐Graphene Thin Films

Advanced Materials Technologies, EarlyView.
The double self‐assembly (DSA) method applied to oxo‐graphene (oxo‐G) flakes followed by hydroiodic acid (HI) vapor treatment and low‐temperature annealing yields highly conductive, optically transparent thin films with the potential for applications in electronic and optoelectronic devices.

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.
