Sarcosine and betaine crystals upon cooling: structural motifs unstable at high pressure become stable at low temperatures

30.12.2014 | E. A. Kapustin; V. S. Minkov; E. V. Boldyreva, Physical Chemistry Chemical Physics, 2014

The crystal structures of N-methyl derivatives of the simplest amino acid glycine, namely sarcosine (C3H7NO2) and betaine (C5H11NO2), were studied upon cooling by single-crystal X-ray diffraction and single-crystal polarized Raman spectroscopy. The effects of decreasing temperature and increasing ...

Reply to Abatzoglou et al.: Atmospheric controls on northwest United States air temperatures, 1948-2012 [Physical Sciences]

30.12.2014 | James A. Johnstone; Nathan J. Mantua, Proceedings of the National Academy of Sciences current issue, 2014

We recently documented a strong relationship between northeast Pacific sea-level pressure (SLP) and coastal North American sea surface temperature (SSTs) and surface air temperatures (SATs), concluding that atmospheric circulation changes produced nearly all observed coastal warming from 1900 to ...
