A study led by Professor Hui Liu from Central South University, published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2024599), introduces a hybrid deep learning model named “ICEEMDAN-LZC-BVMD-SSA-DELM”, which significantly enhances the prediction accuracy of soybean futures prices. By integrating multi-stage data preprocessing and intelligent optimization algorithms, the model addresses limitations of traditional methods in noise handling, parameter tuning, and generalization capabilities, offering new insights for risk management in agricultural financial markets.

Tokyo, Japan – A team led by a researcher from Tokyo Metropolitan University has devised a new way of coating magnesium alloys to improve their corrosion resistance. Instead of costly, unwieldy, and slower coating techniques under vacuum, they used liquid-based chemical conversion coating with the addition of cavitation bubbles. The resulting thick coating helped improve corrosion resistance to chlorides and mechanical properties. The team’s new technology is aimed at reinforcing lightweight materials in electric cars.

Recently, the team led by Academician Wei-Hong Zhu at East China University of Science and Technology proposed a novel photo-rearrangement reaction of diarylethenes induced by intramolecular proton transfer (IPT), while exploring the reactivity of active carbon sites in diarylethene systems. In this study, published in CCS Chemistry, aldehyde and carboxyl groups were innovatively introduced at the active carbon positions, revealing distinct photoresponsive behaviors. The dialdehyde-substituted system exhibited typical reversible photochromism, whereas the dicarboxylate-substituted counterpart underwent an unexpected photorearrangement to yield polycyclic aromatic structures. Mechanistic studies, including transient absorption spectroscopy and density functional theory (DFT) calculations, demonstrated that the rearrangement proceeds through electrocyclization followed by an IPT-driven decarboxylation process. This work opens a new pathway for light-induced synthesis of polycyclic aromatic hydrocarbons and highlights potential applications in molecular modification, photoreaction mechanisms, and synthetic photochemistry.
