Storage light, influence

Fraunhofer rules do not include the influence of refraction, reflection, polarization and other optical effects. Early Iziser particle analyzers used Fraunhofer approximations because the computers of that time could not handle the storage cuid memory requirements of the Mie method. For example, it has been found that the Fraunhofer-based instrumentation cannot be used to measure the particle size of a suspension of lactose (R.I. = 1.533) in iso-octane (R.I. = 1.391) because the relative refractive index is 1.10, i.e.- 1.533/1.391. This is due to the fact that diffraction of light passing through the particles is nearly the same as that passing around the particles, creating a combined interference pattern which is not indicative of the true...

Folate is sensitive to light and may be subject to photodecomposition. Heat treatment influences folate levels in milk. Pasteurization and the storage of pasteurized milks have relatively little effect on the stability of folate but UHT treatments can cause substantial losses. The concentration of oxygen in UHT milk (from the headspace above the milk or by diffusion... 

The relationship between chirality and molecular-level motion is a complex one. Chirality is not an inherent requirement for generating directional motion and yet in some cases it is precisely what causes molecular level motion to proceed in one direction only. New generations of molecular machines will undoubtedly shed more light on this matter for instance in establishing the processes for which chirality is an absolute requirement in their design. Conversely, some molecular machines have the ability to dramatically influence the expression of chirality through controlled submolecular motion. This feature has potential application in data storage, displays and switchable catalysis.
