Stabilization Strategies for Catechins and Epicatechins: Recent Advances

Food Chemistry International, EarlyView.
Oxidation, epimerization, polymerization, and hydrolysis, driven by heat, pH, and oxygen, are pathways. Nano‐/microencapsulation maintains integrity with 70%–95% efficiency; biopolymer nanoparticles, starch/polysaccharide nanocarriers improve stability and dispersion. Lipid nanocarriers enhance bioavailability but raise oxidation risk.

The decadal-scale variation of solar Lyman- and its effects on NLC occurrence rate, NLC brightness and the mesospheric water vapor

Meteorologische Zeitschrift, 2006
Recent 3-D modelling of water vapor in the mesosphere and of NLC volume backscatter coefficient has shown that both parameters are much less influenced by changes in solar Lyman-α flux than hitherto assumed. Long-term satellite observations of seasonally

Operation and expected performance of the NLC main linacs [PDF]

, 1996
The main linacs for the proposed Next Linear Collider (NLC) provide acceleration of up to 500 GeV per beam. The linacs operate in a regime where unavoidable imperfections and even natural ground motion cause significant emittance dilutions.
