Sentiment analysis and satisfaction evaluation of ecotourism consumption under a multi-source deep learning framework

Ecotourism promotes sustainable development, but evaluating tourists’ experiences becomes difficult because of different multi-source feedback. Traditional methods using text or rating have been inaccurate. Research incorporates textual reviews and numerical ratings to enhance pr...

From Antagonism to Coevolutionary Regulation: Multidimensional Phage–Biofilm Interaction Networks and Translational Targeted Anti-Infection Strategies

Bacterial biofilms possess inherent physical barriers and structural heterogeneity. These features pose a major obstacle to clinical anti-infective therapy. This review systematically examines the dynamic interplay between phages and bacterial biofilms, which ranges from antagoni...

Enhanced Anti-thermal Quenching of 3,8-Dibromo-1,10-phenanthroline-Based MOFs for Phosphor-Converted LED

Abstract Diverse coordination geometries of Zn(II) and Cd(II) give rise to distinct halogen bonding interactions and spatial arrangement of the 3,8-dibromophenanthroline luminescent center in two MOFs. The two materials exhibit distinct thermal quenching degrees of 38.9% and 11.9...

Studying the failure mechanism in Li-metal electrode by a reversible fluorescence analysis methodology

Elucidating the failure mechanisms of Li metal electrodes is critical to accelerating the development of long cycle life Li metal batteries. However, it has not yet fully been realized so far due to the challenges associated with quantitative and qualitative characterization of s...

Enantioconvergent Assembly of Chiral Difluoromethyl Stereocenters by Nickel-Catalyzed Reductive Cross-Coupling

Abstract The catalytic asymmetric construction of C(sp3)–CF2H stereocenters remains a longstanding challenge in synthetic and medicinal chemistry. Herein, we report a nickel-catalyzed enantioconvergent reductive cross-coupling strategy that enables efficient access to chiral difl...

Molecular characterization of SGR genes related to abiotic stress resistance in cotton

Stay-green (SGR) genes encode Mg‑dechelatase and play critical roles in chlorophyll degradation. Increasing evidence suggests that SGR genes also participate in abiotic stress responses, including drought and salinity tolerance, in various plant species. However, systematic ident...

Boosted Alkaline Oxygen Evolution Reaction via Phosphorus Incorporation in FeCoS2@MoS2 Core–Shell Heterostructures

Achieving sustainable energy conversion hinges on the rational design of oxygen evolution reaction (OER) electrocatalysts that deliver both high efficiency and low cost. Herein, we report a phosphorus-doped iron-cobalt sulfide/molybdenum sulfide heterostructure on nickel foam (P-...

Enantioselective Convergent Synthesis of Heterohelicenes via Copper-Catalyzed Propargylic Annulation/Acid-Promoted Aromatization

Abstract Heterohelicenes combine helical chirality with tunable electronic properties, making them attractive for applications in chiral materials and optoelectronics. However, their enantioselective synthesis, particularly for five-membered heterohelicenes, remains a long-standi...
