An MTO zeolite catalyst with an ultra-high initial selectivity has been discovered at a low trial-and-error cost through a machine learning (ML)-aidedworkflow. Its etheneselectivity unexpectedly exceeds 60%, presenting thehighest reported value in the field of MTO catalysis.

This study aims to develop methoxy poly(ethylene glycol) (mPEG) and silver-modified magnetite nanoparticles termed Fe3O4@mPEG-Ag NPs as efficient non-antibiotic antibacterial agents to address the growing challenge of drug-resistant bacterial infections.

Study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo. Using cryo-electron microscopy and high-speed atomic force microscopy, they found that LGP2 binds to viral RNA and recruits MDA5 molecules, as if threading beads on a string. This creates a scaffold that facilitates the formation of a large signaling complex, which ultimately triggers an innate immune response.

The transient Pauli blocking effect is a promising way to achieve ultrafast optical switching in semiconductors. Recently, a research team from Japan successfully demonstrated broadband ultrafast optical switching in InN thin films by leveraging pump-probe transient transmittance measurements with multicolor probe lasers. They also developed a theoretical model to explain the underlying mechanism. These findings might pave the way for next-generation ultrafast optical modulators, shutters, and photonic devices in optical computing or optical communication.

Developing high-voltage Ni-rich cathodes with energy densities rivaling ultrahigh-Ni counterparts is highly attractive, but the substantial de-lithiation required under high-voltage operation significantly aggravates strain accumulation and surface degradation. Herein, an in-situ co-precipitation strategy is implemented to synthesize quinary full-concentration-gradient cathode with Mn-rich Ni-poor surface, LiNi_0.73Co_0.05Mn_0.20Al_0.01B_0.01O₂. This design markedly enhances surface mechanical strength and effectively dissipates internal tensile and compressive stresses. Well-distributed B mitigates the de-gradient effect by suppressing heat-driven transition-metal interdiffusion. The occupation of B and Al in tetrahedral interstices of transition-metal and Li layer, respectively, synergistically stabilizes the lattice oxygen, which prevents O₂/CO₂ emission during high state-of-charge (up to 4.5 V) and alleviates structural distortion of the Ni–O coordination environment after extended cycling. The resulting cathode delivers a high capacity of 210.5 mAh g⁻¹ (815.4 Wh kg⁻¹, comparable to 95% Ni cathode) and an initial Coulombic efficiency of 90.1%. It exhibits exceptional long-term cyclability in pouch-type full cells (2.7–4.5 V), retaining 87.3% capacity after 1700 ultra-long cycles. This work presents a practical approach for synthesizing electrochemically stable gradient cathodes suitable for high-voltage operation.
