Proximity-Induced Superconductivity in Ferromagnetic FeGeTe and Josephson Tunneling through a van der Waals Heterojunction.

Synergy between superconductivity and ferromagnetism may offer great opportunities in nondissipative spintronics and topological quantum computing. Yet at the microscopic level, the exchange splitting of the electronic states responsible for ferromagnetism is inherently incompatible with the spin-singlet nature of conventional superconducting Cooper pairs. Here, we exploit the recently discovered van der Waals ferromagnets as enabling platforms with marvelous controllability to unravel the myth between ferromagnetism and superconductivity.

A mitochondria-targeted nanozyme with enhanced antioxidant activity to prevent acute liver injury by remodeling mitochondria respiratory chain.

Developing nanomedicines with enhanced activity to scavenge reactive oxygen species (ROS) has emerged as a promising strategy for addressing ROS-associated diseases, such as drug-induced liver injury. However, designing nanozymes that not only remove ROS but also accelerate the repair of damaged liver cells remains challenging. Here, a two-pronged black phosphorus/Ceria nanozyme with mitochondria-targeting ability (TBP@CeO) is designed.

Room-temperature continuous-wave pumped exciton polariton condensation in a perovskite microcavity.

Microcavity exciton polaritons (polaritons) as part-light part-matter quasiparticles garner considerable attention for Bose-Einstein condensation at elevated temperatures. Recently, halide perovskites have emerged as promising room-temperature polaritonic platforms because of their large exciton binding energies and superior optical properties. However, currently, inducing room-temperature nonequilibrium polariton condensation in perovskite microcavities requires optical pulsed excitations with high excitation densities.

Rhodium-Catalyzed Homogeneous Asymmetric Hydrogenation of Naphthol Derivatives.

Due to their strong aromaticity and difficulties in chemo-, regio-, and enantioselectivity control, asymmetric hydrogenation of naphthol derivatives to 1,2,3,4-tetrahydronaphthols has remained a long-standing challenge. Herein, we report the first example of homogeneous asymmetric hydrogenation of naphthol derivatives catalyzed by tethered rhodium-diamine catalysts, affording a wide array of optically pure 1,2,3,4-tetrahydronaphthols in high yields with excellent regio-, chemo-, and enantioselectivities (up to 98% yield and >99% ee). Mechanistic studies with experimental and computational approaches reveal that fluorinated solvent 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) plays vital roles in the control of reactivity and selectivity, and 1-naphthol is reduced via a cascade reaction pathway, including dearomative tautomerization, 1,4-hydride addition, and 1,2-hydride addition in sequence.

Deep-Learning-Enabled Fast Raman Identification of the Twist Angle of Bi-Layer Graphene.

Twisted bilayer graphene (TBG) has drawn considerable attention due to its angle-dependent electrical, optical, and mechanical properties, yet preparing and identifying samples at specific angles on a large scale remains challenging and labor-intensive. Here, a data-driven strategy that leverages Raman spectroscopy is proposed in combination with deep learning to rapidly and non-destructively decode and predict the twist angle of TBG across the full angular range. By processing high-dimensional Raman data, the deep learning model extracts hidden information to achieve precise twist angle identification.

Mechano-gated iontronic piezomemristor for temporal-tactile neuromorphic plasticity.

In bioneuronal systems, the synergistic interaction between mechanosensitive piezo channels and neuronal synapses can convert and transmit pressure signals into complex temporal plastic pulses with excitatory and inhibitory features. However, existing artificial tactile neuromorphic systems struggle to replicate the elaborate temporal plasticity observed between excitatory and inhibitory features in biological systems, which is critical for the biomimetic processing and memorizing of tactile information. Here we demonstrate a mechano-gated iontronic piezomemristor with programmable temporal-tactile plasticity.

Green process for xylo-oligosaccharide production from acetic acid hydrolysis of sugarcane bagasse by an integrated membrane technology and activated carbon adsorption.

Xylooligosaccharides (XOS), consisting 2-6 xylose residues, are a new type of prebiotic and functional oligosaccharides, and can usually be produced from the xylan-riched lignocellulosic biomass by acetic acid (HAc) hydrolysis, while the waste HAc was a problem to the environment. In this study, the main aim was to recover and reuse the waste HAc in XOS production. First, it was found that a temperature of 190 °C and a hydrolysis time of 60 min were favorable for XOS production by HAc hydrolysis, and the by-products xylose and furfural were the main inhibitors, hindering the reuse of the waste HAc.

Ultralow Coordination Copper Sites Compartmentalized within Ordered Pores for Highly Efficient Electrosynthesis of -Propanol from CO.

Coordinatively unsaturated copper (Cu) has been demonstrated to be effective for electrifying CO reduction into C products by adjusting the coupling of C-C intermediates. Nevertheless, the intuitive impacts of ultralow coordination Cu sites on C products are scarcely elucidated due to the lack of synthetic recipes for Cu with low coordination numbers and its vulnerability to aggregation under reductive potentials. Herein, computational predictions revealed that Cu sites with higher levels of coordinative unsaturation favored the adsorption of C and C intermediates.

Coherent Exciton Spin Relaxation Dynamics and Exciton Polaron Character in Layered Two-Dimensional Lead-Halide Perovskites.

The quantum-well-like two-dimensional lead-halide perovskites exhibit strongly confined excitons due to the quantum confinement and reduced dielectric screening effect, which feature intriguing excitonic effects. The ionic nature of the perovskite crystal and the "softness" of the lattice induce the complex lattice dynamics. There are still open questions about how the soft lattices decorate the nature of excitons in these hybrid materials.
