Relating hygroscopicity and composition of organic aerosol particulate matter [PDF]

open access: yes, 2010
A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the chemical and photochemical oxidation of several organic precursors in a smog chamber.

Hygroscopic Coffer

open access: yesInterdisciplinary Perspectives on the Built Environment, 2022
The integration between renewable materials and passive design strategies for the improvement of the built environment comfort leads to a reduction in energy consumptions and in the use of active HAVC systems. Sustainability concerns the materials employed, but also their performance: natural materials with embedded responsive properties respond to ...
