An infrared measurement of chemical desorption from interstellar ice analogues [PDF]

open access: yes, 2018
In molecular clouds at temperatures as low as 10 K, all species except hydrogen and helium should be locked in the heterogeneous ice on dust grain surfaces. Nevertheless, astronomical observations have detected over 150 different species in the gas phase

Adsorption-desorption kinetics in nanoscopically confined oligomer films under shear [PDF]

open access: yes, 1995
The method of molecular dynamics computer simulations is employed to study oligomer melts confined in ultra-thin films and subjected to shear. The focus is on the self-diffusion of oligomers near attractive surfaces and on their desorption, together with

Moisture adsorption-desorption full cycle power generation

open access: yesNature Communications, 2022
Environment-adaptive power generation can play an important role in next-generation energy conversion. Herein, we propose a moisture adsorption-desorption power generator (MADG) based on porous ionizable assembly, which spontaneously adsorbs moisture at ...
