TL;DR: In this article, two graphite types, namely graphite flakes (GF) and expanded natural graphite (ENG), have been tested at constant PCM content in the nodule.

TL;DR: In this paper, thermal storage composites made of graphite and PCM (NaNO 3 /KNO 3 eutectic) have been developed for solar thermal power plants using direct solar steam generation.

TL;DR: In this article, carbonized coconut shells at different intermediate heat treatment temperatures (IHTT) between 400 and 800 °C were activated at 800°C in a stream of N2+H2O, following two distinct procedures.

TL;DR: In this article, a simple textural model of activated carbon porosity was used to test a simple texture model of porosity proposed in the recent literature, and the results showed that the gradual obtained microporosities cover a wide and valuable range of porous textures highly dependent on the initial material origin and initial activation.

TL;DR: Two complementary wearing off cycling methods based on an initial wet oxidation in a sodium hypochlorite solution or an initial dry oxidation under air, both followed by a thermal pyrolysis under nitrogen, have been applied to a same carbon molecular sieve to study its gradual pore structure modifications.
