A research team led by Prof. TAN Peng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has revealed the temperature regulation mechanism of lithium-mars gas batteries (LMGBs), providing a theoretical foundation for the design of next-generation deep space exploration energy batteries. The study was published in Advanced Functional Materials.

In a study published in Reports on Progress in Physics, research teams led by Academician GUO Guangcan and Prof. LIU Biheng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with Origin Quantum Computing Company Limited, achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting quantum systems, completing the self-checking of the five-qubit error correction code space.

A team led by Prof. DONG Chunhua from the University of Science and Technology of China (USTC), in collaboration with Prof. BO Fang's group from Nankai University, has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman effects within one microresonator, the microcomb has a spectral width exceeding 300 nm and a repetition rate of 26.03 GHz, without the need for external electronic feedback. The research was published in the Nature Communications.

This work integrates phase gradient control with Floquet periodicity, systematically revealing the "missing" harmonic dynamics in the Generalized Snell’s Law (GSL). Through deterministic Floquet-engineered momentum compensation, target harmonics are selectively activated, transforming spatial harmonic components into independently tunable degrees of freedom—culminating in the Spatial Harmonic-expanded Generalized Snell’s Law (SH-GSL). This paradigm shifts traditional gradient metasurface research from "avoiding inter-unit coupling" to "precisely regulating strong inter-unit coupling". The work systematically elucidates the dynamics of high-order spatial harmonics in gradient metasurfaces, shaping the core physics of "full-channel metasurfaces," and provides theoretical and engineering pathways for ultra-dense beamforming, reconfigurable multichannel sensing, and generalized metasurface device design under strong coupling paradigms.

A study published in the Journal of Bioresources and Bioproducts explores the potential of converting pineapple peel waste into nanocellulose fibers to enhance sandy soils. Using mechanochemical processes, researchers obtained fibers that improved soil water-holding capacity, reduced evaporation, and increased nutrient retention. Tested in United Arab Emirates desert sands, the amendments enhanced soil mechanics and supported tomato plant growth at optimal concentrations. The findings highlight a scalable and sustainable strategy to repurpose food waste for soil restoration and agricultural productivity in arid environments.

Liang Deng's group at the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, recently discovered that a dinuclear cobalt carbonyl complex [(Xantphos)Co₂(CO)₆] coordinated by the bidentate phosphine ligand Xantphos can effectively catalyze the selective anti-Markovnikov hydrosilylation reaction of terminal alkynes with tertiary silanes. In collaboration with Hui Chen's group at the Institute of Chemistry, Chinese Academy of Sciences, they conducted experimental and theoretical exploration of the reaction mechanism and found that the (Xantphos)(CO)Co site in the dinuclear cobalt catalyst can be viewed as a ligand, cooperating with the Co(CO)_n site to achieve the activation transformation of the covalent bond in the catalytic reaction. This research result was published in CCS Chemistry.

SAN ANTONIO — September 22, 2025 — Southwest Research Institute (SwRI) is managing the payload of instruments aboard NASA’s Interstellar Mapping and Acceleration Probe (IMAP) spacecraft scheduled to launch Wednesday, September 24, 2025 at 7:30 a.m. EST from Kennedy Space Center in Florida. The payload, including the SwRI-developed Compact Dual Ion Composition Experiment (CoDICE) instrument, will study the interaction between the solar wind and the interstellar medium that surrounds it.
