Acceptor Elongation Boosted Intersystem Crossing Affords Efficient NIR Type-I and AIE-Active Photosensitizers for Targeting Ferroptosis-Based Cancer Therapy.

Photosensitizers (PSs) featuring type I reactive oxygen species (ROS) generation and aggregation-induced emission (AIE) activity offer a promising solution to achieve non-invasive and precise theranostics. However, the reported AIE luminogens (AIEgens) with both AIE characteristic and strong type-I ROS generation are still scarce and the structure-property relationship is still unclear. Herein, an innovative acceptor elongation boosted intersystem crossing (AEBIC) design strategy has been proposed to endow the AIEgen strong type-I ROS producibility.

Autonomous Self-Healing Magnetoelectric I-Skin from Self-Bonded Deep Eutectic Polymer.

Next-generation ionic skin (i-skin) should be self-healing and self-powered, promoting its development toward lightweight, miniaturization, compact, and portable designs. Previously reported self-powered i-skin mostly either lack the ability to self-repair damaged parts or only have self-healing capabilities some components, falling short of achieving complete device self-healability. In this work, a self-bonding strategy is presented to obtain an all-polymerizable deep eutectic solvent (PDES) magnetoelectric i-skin (MIS) that simultaneously achieves self-powering and full-device autonomous self-healability.

Destabilization of Single-Atom Catalysts: Characterization, Mechanisms, and Regeneration Strategies.

Numerous in situ characterization studies have focused on revealing the catalytic mechanisms of single-atom catalysts (SACs), providing a theoretical basis for their rational design. Although research is relatively limited, the stability of SACs under long-term operating conditions is equally important and a prerequisite for their real-world energy applications, such as fuel cells and water electrolyzers. Recently, there has been a rise in in situ characterization studies on the destabilization and regeneration of SACs; however, timely and comprehensive summaries that provide the catalysis community with valuable insights and research directions are still lacking.

However, most of the natural food-derived functional peptides need to overcome a variety of barriers in the body to enter the blood circulation system and target to specific tissues to generate physiological activity.

Efficacy of Supportive Care Interventions for Improving Posttraumatic Stress Symptoms and Resilience in Family Caregivers of Cancer-Affected Children: A Meta-Analysis of Randomized Controlled Trials.

Background: The diagnosis of pediatric cancer is a major shock to family caregivers, and posttraumatic stress symptoms (PTSSs) emerge as the most prevalent adverse psychological outcomes. However, not all family caregivers have sufficient resilience to cope with these challenges; thus, supportive care interventions are necessary. These interventions, which include psychosocial support, education, and other forms of assistance, are designed to enhance the well-being of those affected by disease.

Untangling the impacts of bacterial community on carbon dioxide and nitrous oxide across a drinking water reservoir.

Reservoirs represent a critical component of greenhouse gas (GHG) emissions, yet the intricacies of how biotic and abiotic factors influence GHG dynamics within reservoirs remain largely unexplored. Herein, we investigated the spatiotemporal patterns of CO and NO emissions and the underlying factors in the Danjiangkou Reservoir, Asia's largest artificial freshwater reservoir. We found that this reservoir was a significant source of GHGs to the atmosphere, with peak CO emissions observed in autumn (1544.

Identification of correlation relationships and establishment of regression models among multiple microbial indicators in reclaimed waters.

Monitoring and controlling microbial water quality is crucial for ensuring water reuse safety. In particular, existing water reuse guidelines and regulations normally prescribed coliform bacteria as microbial indicators. However, the use of non-unified coliform groups may bring difficulties to compare and optimize the conformity efforts on microbial surveillance.

Effects of extrusion temperature on structure and physicochemical properties of proso millet starch.

Due to its thermal stability, and high viscosity, proso millet starch has limited practical applications. Extrusion can alter the functional properties of starch by pre-gelatinization, but the specific effects of extrusion temperature on starch behavior are not clear. In this study, proso millet starch was modified using extrusion at varying temperatures (70 °C, 90 °C, 110 °C), and its structure as well as physicochemical properties were evaluated.

β-Aminobutyric acid activates SA-signalling systemic acquired resistance in peach fruit by suppressing the circadian clock associated protein1.

Circadian clock regulates plant development and physiology by anticipating daily environmental changes. Here we studied the core clock protein involved in β-aminobutyric acid (BABA)-inducible SAR resistance to Rhizopus stolonifer in peach fruit. BABA elicitation barely primed the accumulation of jasmonate or ethylene, whose regulation was associated with morning-loop gene expression.

Hairy chitin nanocrystals: Sustainable adsorbents for efficient removal of organic dyes.

Chitin nanocrystals (ChNCs) are typically produced using a combination of strong acid hydrolysis and mechanical treatments. In this study, a mild, energy-efficient, and environmentally friendly method was developed to prepare a novel form of chitin nanocrystals called hairy chitin nanocrystals (HChNCs) without the need of any mechanical treatments. The HChNCs were made by sequential oxidations on partially deacetylated chitin, resulting in a unique morphology with chitin molecular chains protruding from central chitin nanorods.
