Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications

Advanced Materials Technologies, EarlyView.
We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

Roll‐to‐Roll Manufacturing of Flexible Thermoelectric Semiconductors Using Low‐Level Direct‐Current Sputtering

Advanced Materials Technologies, EarlyView.
Roll‐to‐roll direct‐current sputtering enables room‐temperature manufacture of flexible bismuth telluride thermoelectric films. By identifying a low‐power deposition window that suppresses charge‐induced arcing, this work links sputtering conditions to film structure, charge transport, and thermoelectric performance, achieving a room‐temperature figure

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

Advanced Materials Technologies, EarlyView.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Recyclable and Binder‐Free EGaIn–Carbon Liquid Metal Composite: A Sustainable Approach for High‐Performance Stretchable Electronics, Thermal‐Interfacing and EMI‐Shielding

Advanced Materials Technologies, EarlyView.
Binder‐free EGaIn–CB composite deliver printable, recyclable liquid‐metal conductors without sintering or polymer binders. Only 1.5 wt% CB yields shear‐thinning, high‐viscosity rheology, ∼60% bulk EGaIn conductivity, robust stretchability, high thermal conductivity, and strong EMI shielding (35 → 70 dB at 100% strain).
