Size Determination Of Vitamin B1 By Dynamic Light Scattering
2016-01-11 11:55:19| oilandgasonline Downloads
Dynamic light scattering (DLS) is a physics technique used for characterizing the size of particles and molecules in suspension and solution. The technique is based on the measurement of the time-dependent fluctuations in the intensity of the scattered light signals. The particles are responsible for the scattering of the light, while it is the random motion of the particles that produces the fluctuations in that scattering. By measuring the scattering, the particles' velocity can be derived, and from that velocity the hydrodynamic diameter of the particles can be calculated by using the Stokes–Einstein equation.

Vitamin B3 may have originally come from space, arrived via meteorites
2015-08-04 20:00:45| Extremetech
The discovery of vitamin B3 in meteorites is a fascinating new clue to the origin of life. Researchers have now been able to reproduce in the lab a plausible mechanism for how vitamin B3 could have been synthesized by the action of radiation on starter molecules in interstellar ices.
