where a B = 0.053 nm is the Bohr radius, m is the mass, μ is the reduced mass, and ε r is the size-dependent dielectric constant (relative permittivity). This results in the increase in the total emission energy (the sum of the energy levels in the smaller band gaps in the strong confinement regime is larger than the energy levels in the band ...

In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...
EC 50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/L. The EC 50 of a graded dose response curve therefore represents the concentration of a compound where 50% of its maximal effect is observed. [ 4 ]
Surface roughness, often shortened to roughness, is a component of surface finish (surface texture).It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form.
Structure and properties Index of refraction, n D: 1.000449 at 589.3 nm and 0 °C [1]: Dielectric constant, ε r: 1.60 ε 0 at 0 °C, 50 atm : Average energy per C=O bond : 804.4 kJ/mol at 298 K (25 °C) [2]
The spike at 460 nm and dip at 500 nm can make the color of objects appear differently under cool-white LED illumination than sunlight or incandescent sources, due to metamerism, [67] red surfaces being rendered particularly poorly by typical phosphor-based cool-white LEDs. The same is true with green surfaces.
While no scientist has stated to believe GJ 1214 b is an ocean planet, if GJ 1214 b is assumed to be an ocean planet, [22] i.e. the interior is assumed to be composed primarily of a water core surrounded by more water, proportions of the total mass consistent with the mass and radius are about 25% rock and 75% water, covered by a thick envelope ...
