The single particle relaxation dynamics of hydrogen atoms in different oxomolybdate Keplerate type nanocages characterized by a (metal) 30 icosidodecahedron and...
The velocity divergence (rate of fluid volumetric expansion) is a flow field quantity of fundamental importance in low-Mach flows. It directly affects the local...
The oxidation of hydrocarbon fuels proceeds through the attack of small radicals such as H and CH3 on large molecules. These radicals abstract H atoms from the...
Using a quantum-optics technique known as Electromagnetically Induced Transparency (EIT) and Autler-Townes splitting, we present a technique for sub-wavelength...
