A joint research team has developed a novel Bethe ansatz–based algorithm introducing the concept of relative excitations, enabling exact calculations of one-dimensional Bose gases at arbitrary interaction strengths. They achieved the first full spectral function solution at large system sizes (4000 particles) and quantitatively confirmed the nonlinear Luttinger liquid theory. This breakthrough provides a powerful new tool for studying strongly correlated quantum systems and guiding future experimental and theoretical research.

Chinese scientists have significantly improved the efficiency of converting carbon dioxide (CO₂) into fuel using sunlight. By introducing controlled "tension" (lattice strain) into specially designed perovskite nanowires, they achieved a fivefold increase in carbon monoxide (CO) production rate compared to unstrained materials. This breakthrough, published in Science Bulletin, leverages strain to manipulate "polaron" quasiparticles, slowing charge recombination and lowering reaction barriers, paving the way for more efficient solar fuel production.

Elongation and rapid compression of Fe-Fe atomic pairs in Fe-Ni alloys have been probed as the atomic scale origin of the invar effect and the large magnetovolume effect in Fe-Ni disordered alloys. We investigated the Ni-content dependence of bulk modulus of Fe-Fe, Fe-Ni, and Ni-Ni atomic pairs in the fcc-based in Fe-Ni alloys using reverse Monte Carlo modeling with a dataset of extended x-ray absorption fine structure and powder x-ray diffraction under high pressure.

A comprehensive review published in Nitrogen Cycling highlights significant advances in understanding the soil nitrogen cycle, emphasizing the critical role of microbial processes and innovative technologies in achieving global nitrogen sustainability.

A long-term field study conducted in Northeast China’s fertile black soil region has demonstrated that biochar can significantly improve soil health, stabilize microbial communities, and increase crop yields—but only when applied at the right rate.

In a groundbreaking study that combines innovative material science with environmental engineering, researchers are exploring how phosphorus-modified bamboo biochar can effectively immobilize Cd(II) ions in solution. The study, titled "Immobilization of Cd(II) by Phosphorus-Modified Bamboo Biochar from Solution: Mechanistic Study from Qualitative to Quantitative Analysis," is led by Prof. Guangcai Chen from the Research Institute of Subtropical Forestry at the Chinese Academy of Forestry in Hangzhou, China, and Prof. Zhengguo Song from the Department of Materials and Environmental Engineering at Shantou University in Shantou, China. This research offers a detailed examination of the adsorption mechanisms and soil amelioration potential of this novel biochar.
