All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...

This study addresses the challenges of mobile‐ion‐induced instability in perovskite solar cells. Introducing bilayer passivation with ammonium salts (EDAI₂/PEAI and ABS/PEAI) significantly reduces ion density and improves device stability. The approach mitigates the detrimental effects of PEAI‐induced ionic losses, enhancing both performance and ...

Colonoscopic continuum robots lack sensing, endangering intestinal tissue. An ideal sensing array is hard to integrate. This work introduces a 3D crosslinked stretchable E‐armor with full‐coverage and multiplexing. It has bimodal sensing, forms a triboelectric synapse, uses CNN‐LSTM, and has a hydrogel and innovative triboelectric materials.

Deep Eutectic Solvents Formed by Complex Hydrides: A New Class of Hydrogen‐Rich Liquid
This work discovers a new type of deep eutectic solvent composed of ammonia borane (NH3BH3, AB) and tetrabutylammonium borohydride (TBABH). The new liquids possess a hydrogen content higher than 5 wt%, thus representing promising high‐energy liquid hydrogen carriers. The strong hydrogen bonding between AB and TBABH explains the depletion of the melting

The coexistence of ferromagnetic and antiferromagnetic orders in van der Waals magnet above room temperature, inducing an intrinsic exchange bias and canted perpendicular magnetism is discovered. Such non‐trivial intrinsic magnetic order enables the realization of energy‐efficient and magnetic field‐free spin‐orbit torque memory devices.

Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...
