Silver nanoclusters (AgNCs) were first coated with bovine serum albumin (BSA) and then encapsulated into porous metal–organic frameworks of ZIF-8 by the protein-mediated biomineralization process. Unexpectedly, fluorescence intensities yielded AgNCs-BSA@ZIF-8 nanocomposites discovered to be continuously enhanced during each BSA coating encapsulation steps. Compared common AgNCs, greatly improved photostability storage stability AgNCs could also expected. More importantly, having benefited...

The utilization of visible light to split water into H₂ and O₂ offers a promising solution address the escalating global energy crisis environmental pollution. Compared conventional three‐dimensional (3D) photocatalysts, anisotropic two‐dimensional (2D) materials exhibit enhanced photocatalytic activity due their ultrahigh surface area, reduced charge migration distance, improved efficiency.

This paper presents an approach for cooperative search of a team distributed agents. We consider two or more agents, vehicles, moving in geographic environment, searching targets interest and avoiding obstacles threats. The agents are equipped with sensors to view limited region the environment they visiting, able communicate one another enable cooperation. assumed have some "physical" limitations including possibly maneuverability limitations, fuel/time constraints sensor range accuracy....

Abstract The control of networked multivehicle systems designed to perform complex coordinated tasks is currently an important and challenging field research. This paper addresses a cooperative search problem where team uninhabited aerial vehicles (UAVs) seeks find targets interest in uncertain environment. We present practical framework for online planning group UAVs based on two interdependent tasks: (i) incrementally updating “cognitive maps” used as the representation environment through...

Autophagy caused by ischemia/reperfusion (I/R) increases the extent of cardiomyocyte damage. Melatonin (Mel) diminishes cardiac injury through regulating autophagy and mitochondrial dynamics. However, illustrating specific role mitophagy in cardioprotective effects melatonin remains a challenge. The aim our research was to investigate impact underlying mechanisms connection with during anoxia/reoxygenation (A/R) H9c2 cells.H9c2 cells were pretreated or without membrane receptor 2 (MT2)...

Polyoxometalates (POMs) have attracted extensive interests as solid-state proton conductors due to their high conductivity and good thermal stability.However, the low humidity stability poor mechanical property of crystalline POMs greatly hinder practical application.Herein, on basis remarkable improvement that can be achieved by hybridizing with organic components, we prepared a new POM-based inorganic-organic hybrid, H[Zn(Hapca3-anions Zn(Hapca) 3 2+ cations.Compound 1 exhibits 1.16 × 10...

Photocatalytic reduction of U(VI) is a promising method for removing uranium containing pollutants.

Mechanical ventilation is an effective treatment for acute respiratory distress syndrome (ARDS), which can improve the prognosis of ARDS to a certain extent. However, it may further aggravate lung tissue injury, defined as ventilator-induced injury (VILI). Intermedin (IMD) belongs calcitonin gene-related peptide (CPRP) superfamily. Our previous studies have found that IMD reduces expression proinflammatory cytokines, down-regulates nuclear translocation and improves integrity endothelial...
