Viability of Brazilwood seeds (Caesalpinia echinata Lam.) stored at room temperature in controlled atmospheres

Journal of Seed Science, 2015
Seed storage at room temperature is an important and low-cost tool for ex situ conservation. However, the high rates of seed deterioration could reduce the potential for storage in this condition.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Reformulating atmospheric aerosol thermodynamics and hygroscopic growth into fog, haze and clouds [PDF]

Atmospheric Chemistry and Physics, 2007
Modeling atmospheric aerosol and cloud microphysics is rather complex, even if chemical and thermodynamical equilibrium is assumed. We show, however, that the thermodynamics can be considerably simplified by reformulating equilibrium to consistently ...
