Direct electrocatalytic depolymerization of lignin using a thermally stable organic salt electrolyte: performance and mechanistic insights.

Electrochemical depolymerization of lignin to produce low molecular weight aromatic compounds is characterized by mild conditions and low carbon emissions. However, using non-metallic catalysts for this process faces challenges in terms of selectivity and activity. This study found that high-melting-point organic salts - tetra-n-butyl tetrafluoroborate (TBABF), can function simultaneously as a catalyst and oxidant at room temperature and in air, effectively catalyzing the CO bond cleavage in lignin.

A network approach to the relationship between adolescents' problem behaviors, psychological abuse and neglect, and school connectedness.

The impact of reading trauma literature on Chinese undergraduates' PTSD: the mediating roles of social support and empathy.

Trauma literature has emerged as a powerful medium for exploring collective and individual psychological experiences. However, its the potential psychological risks—particularly its association with PTSD symptoms among students—have not been thoroughly examined, especially in the context of Chinese undergraduates who face unique academic and social pressures. This study investigates the impact of trauma literature on PTSD symptoms, with a focus on the mediating roles of social support and empathy.

Comments on Two Controversial Oriental Assassin Bug Species of the Genus (Heteroptera: Reduviidae: Harpactorinae), with the Description of sp. nov. from China.

The two closely related Oriental species of the genus , (Stål, 1867) and (Fabricius, 1787), exhibit remarkable morphological similarity, particularly in their overall red and black body coloration, including the head, thorax, and abdomen. Based on the examination of type specimens and non-type material collected from various localities of southern China, we found these two congeners were misidentified in many previous publications. Due to the restricted distribution and limited population size of in China, most taxonomic, biological, and biocontrol studies conducted under the name or should be instead attributed to To address this confusion regarding these two species, the present study clarifies the taxonomic status of the two controversial species- and .

Redox-coupled coordination strategy for xanthate detoxification via self-catalysis over a broad pH range.

This study developed an effective strategy to construct a Cu(II)/Cu(I) redox cycle catalytic system by anchoring Cu(II)/Cu(I) onto multi-walled carbon nanotubes (MWCNTs) via wet ball milling for the efficient degradation of xanthate compounds. The catalyst exhibited dual functionality: Cu(II) coordinated with electron-rich S-CS moiety in xanthate molecules, facilitating strong adsorption of xanthate and generation of stable Cu(I), which subsequently activated HO to regenerate Cu(II) and generate reactive oxygen species (•OH, •O⁻, and O). DFT calculations verified the enhanced adsorption of xanthate.

An examination of the decoupling effect and influential mechanisms of energy consumption and economic growth in Chinese urban areas.

Under the "dual-carbon" target and the shift towards a high-quality economy, achieving a decoupling of energy consumption from economic growth is crucial.

A unified cell atlas of vascular plants reveals cell-type foundational genes and accelerates gene discovery.

The pace of gene discovery in plants has slowed as forward genetic screens reach saturation. To address this, we built a unified single-cell atlas of shoot apices from six vascular plant species spanning major evolutionary groups. This cross-species resource allowed us to identify a core set of cell-type foundational genes linked to key tissues such as the epidermis, xylem, and phloem, streamlining gene discovery with greater accuracy.

partial vulcanization synthesis of a conductive and highly catalytic bimetal organic framework for sensitive electrochemical cancer-specific neoantigen detection.

Neoantigens are unique tumor-derived epitopes to facilitate the development of immunotherapeutic interventions and advance the precision diagnosis of cancers. However, significant challenges remain in the detection of these neoantigens due to their inert electrochemical/fluorescent properties and low abundance, and mass spectroscopy is currently the prevailing neoantigen analysis platform, constrained by procedural complexity, prohibitive cost, and isotopic tagging. Based on partial vulcanization synthesis of a new conductive bimetal organic framework and a peptide derivatization strategy, we demonstrate an innovative catalysis-enhanced electrochemical neoantigen biosensing platform for direct and specific electrochemical cancer diagnosis.
