Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well those reached directly at high energy colliders. Discrimination between different models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss current status prospects near future a compelling suite such experiments, along with developments needed encompassing theoretical framework.

The use of biodegradable materials combined with natural metabolites in wound dressings has received much attention. Flavonoids (FLs) from green cocoons, as metabolites, have antibacterial, antioxidant, anti-inflammatory, and other pharmacological effects. In this study, composite membranes FL-loaded polylactic glycolic acid (PLGA)/silk fibroin (SF) were prepared by an electrospinning method. membranes, including SF, exhibited a good slow-release effect cytocompatibility. An vitro evaluation...

Multiple field studies have led to suggestions that nitrate radical (NO3) participates in oxidizing gaseous Hg(0) the atmosphere. These suppositions are hard reconcile with two-step mechanism of conversion Hg(II) via Hg(I), due instability NO3-Hg(I). We use a high level computational chemistry determine its bond energy as 6.5 kcal mol-1. statistical mechanics compute equilibrium constant, Kc(T) for NO3 + = NO3Hg(I), and box model investigate study laboratory kinetic investigation this...
