Facile On-Substrate Fabrication of Silver Coordination Polymer Nanowires for Sustainable and Efficient Water Disinfection.

Silver, as the oldest antibacterial material, has been almost replaced by other alternatives for its insufficient activity or potential side-effects on the ecosystem due to the over-release of Ag ions (Ag). Herein, a facile and general strategy is developed to on-substrate fabricate silver coordination polymer nanowire arrays (Ag CPN) by simply immersing Ag-containing substrates into cationic surfactant solution at room temperature. Such a Ag CPN not only provides high-surface-area nano-biointerfaces for destroying microorganisms via physicomechanical interactions but also acts as a safe Ag reservoir, steadily releasing Ag at a relatively high but safe level (∼40 ppb, but lower than the safe level of 100 ppb).

A new approach in generating stable crack propagation at twisted bilayer graphene/hBN heterostructures.

Thermodynamic theory suggests that the obvious mechanical behavior caused by temperature and interlayer angle will affect the physical properties of materials, such as mechanical properties and transportation behavior, and it is different from the behavior in three-dimensional bulk materials. We observe an abnormal physical effect of bilayer graphene/hexagonal boron nitride (G/BN)-carbon nanotube (CNT) heterostructures, with a normalized out-of-plane deformation and normalized bond angle percentage to almost several times higher those of pristine G/BN heterostructures (without CNT) at 700-800 K. Our combined finite element theory and molecular dynamics simulations confirmed that the combination of CNT and interlayer angle diverted and bridged the propagating crack and provided a stable crack propagation path and crack tip opening displacement, resulting in the stress fields to be controlled around the CNT at high temperature.

Exploring the pharmacological mechanisms for alleviating OSA: Adenosine A2A receptor downregulation of the PI3K/Akt/HIF‑1 pathway (Review).

Obstructive sleep apnea (OSA) is the most common type of sleep apnea, which leads to episodes of intermittent hypoxia due to obstruction of the upper airway. A key feature of OSA is the upregulation and stabilization of hypoxia-inducible factor 1 (HIF-1), a crucial metabolic regulator that facilitates rapid adaptation to changes in oxygen availability. Adenosine A2A receptor (A2AR), a major adenosine receptor, regulates HIF-1 under hypoxic conditions, exerting anti-inflammatory properties and affecting lipid metabolism.
