Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

BMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

Field‐free programmable bipolar magnetic heterostructures for neuromorphic computing

InfoMat, EarlyView.
Neuromorphic computing mimics the brain's efficiency, yet typical memristors lack biological synapses' dual signal control. We introduce a magnetic memristor enabling bidirectional, multi‐state modulation without external fields, validated in image feature extraction and neural clustering.

Photoinduced Picosecond‐Scale Radial Current for Generating and Converting Spin Textures

Nanophotonics, Volume 15, Issue 7, 13 April 2026.
A picosecond‐scale vector electrical current is generated and applied to generate and convert spin textures. Four target quasiparticle types with different topological states are generated with ultrafast speed (< 50 ps). Besides, the controlled transitions between these spin textures are achieved. ABSTRACT Magnetic skyrmions are topologically protected

Field-free spin-orbit torques switching and its applications

npj Spintronics
We review various approaches to field-free spin-orbit torque (SOT) switching. One approach involves introducing in-plane symmetric breaking methods to conventional SOT, such as an in-plane effective magnetic field or magnetic anisotropy, spatial non ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.
