Synthesis and catalytic applications of combined zeolitic/mesoporous materials

open access: yesBeilstein Journal of Nanotechnology, 2011
In the last decade, research concerning nanoporous siliceous materials has been focused on mesoporous materials with intrinsic zeolitic features. These materials are thought to be superior, because they are able to combine (i) the enhanced diffusion and ...

Net, excess and absolute adsorption and adsorption of helium [PDF]

open access: yesAdsorption, 2016
The definitions of absolute, excess and net adsorption in microporous materials are used to identify the correct limits at zero and infinite pressure. Absolute adsorption is shown to be the fundamental thermodynamic property and methods to determine the solid density that includes the micropore volume are discussed.

A Study of the Removal of Minor Amounts of HS from Natural Gas by Activated Carbon

open access: yesAdsorption Science & Technology, 2002
Studies have been made of the removal of minor amounts of H 2 S from natural gas by activated carbon. The surface alkalinity of the carbon had a considerable effect on the H 2 S capacity, although this was not permanent.

Upcycling polyethylene into closed-loop recyclable polymers through titanosilicate catalyzed C-H oxidation and in-chain heteroatom insertion

open access: yesNature Communications
Polyolefins are the most widely produced type of plastics owing to their low production cost and favorable properties. Their polymer backbone consists solely of inert C-C bonds, making them resistant and durable materials.
