Isosteric heat of adsorption for water adsorbed on ThO2

open access: yesCHIMIA, 1972
The isosteric heat of adsorption for water on ThO2 was measured as a function of the surface coverage. The ΔHst-values referring to the formation of the second and third monolayer are smaller than the heat of liquefaction of pure water.

Equilibria and isosteric heat of adsorption of methane on activated carbons derived from South African coal discards [PDF]

open access: yesACS Omega, 2020
: Isosteric heat of adsorption (Hst) is critical for evaluating the thermal effects of adsorption-based storage systems. Poor management of the thermal effects of an adsorptive storage system often alters the overall performance of the storage system. In

Pore‐Hierarchy Engineering of Cigarette Butt Waste Into Porous Carbon for CO2 Adsorption [PDF]

open access: yesGlobal Challenges, Volume 10, Issue 10, October 2026.
Whole cigarette‐butt waste is converted into porous carbon by carbonization and Na2CO3 activation. Varying Na2CO3 loading regulates pore development and CO2 uptake, with WCB‐83 adsorbing 3.0 mmol g−1 at 273 K and 1 bar. The study links waste valorization with pore‐structure control in carbon adsorbents. ABSTRACT Cigarette butts are a persistent plastic‐
