"Suspended" Single Rhenium Atoms on Nickel Oxide for Efficient Electrochemical Oxidation of Glucose.

Well-defined single-atom catalysts (SACs) serve as ideal model systems for directly comparing experimental results with theoretical calculations, offering profound insights into heterogeneous catalytic processes. However, precisely designing and controllably synthesizing SACs remain challenging due to the unpredictable structure evolution of active sites and generation of embedded active sites, which may bring about steric hindrance during chemical reactions. Herein, we present the precious nonpyrolysis synthesis of Re SACs with a well-defined phenanthroline coordination supported by NiO (Re-phen/NiO).

The mosquito evolves two types of prophenoloxidases with diversified functions.

Insect phenoloxidase, presented as an inactive precursor prophenoloxidase (PPO) in hemolymph, catalyzes melanin formation, which is involved in wound healing, pathogen killing, reversible oxygen collection during insect respiration, and cuticle and eggshell formation. Mosquitoes possess 9 to 16 PPO members across different genera, a number that is more than that found in other dipteran insects. However, the reasons for the redundancy of these PPOs and whether they have distinct biochemical properties and physiological functions remain unclear.

The Repair of Large Maxillary Sinus Membrane Perforations with a Collagen Membrane Stabilized with Tacks on the Medial and Lateral Walls: A Technical Note.

Sinus membrane perforations are among the most commonly reported intraoperative complications encountered during maxillary sinus floor elevation procedures performed via the lateral window approach. Large perforations (> 10 mm) can pose a major clinical challenge, and often result in failed bone augmentation and poorer long-term implant survival. Owing to these challenges, even a highly skilled oral implant surgeon with advanced training in implantology faced with such perforations may abandon grafting procedures in favor of a reentry approach.
