Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption
Advanced Materials Interfaces, EarlyView.The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...

Surface Properties of p‐GaN and Formation of Nickel Metal Contacts
Advanced Materials Interfaces, EarlyView.The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...

Advanced Materials Interfaces, EarlyView.The surface chemistry and core composition of Ti3C2Tx MXenes is often derived from X‐ray Photoelectron Spectroscopy (XPS) but its determination and quantification remain difficult due to adsorbed species such as adventitious carbon. This challenge is overcome by using energy‐dependent XPS and depth profile modeling of the Ti3C2Tx MXene surface ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Advanced Materials Technologies, EarlyView.This study presents a braided fiber‐reinforced sleeve that amplifies strain in soft materials, enhancing their performance in stretchable devices like sensors and energy harvesters. By reinforcing and elongating encased materials, the sleeve increases the “effective” strain.

Advanced Materials Technologies, EarlyView.This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.
