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 ...

Study of Methane Storage and Adsorption Equilibria in Multi-Walled Carbon Nanotubes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2008
Adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. Carbon nanotubes can be introduced as a new candidate for natural gas storage.

Possible role of organic matter in radiocaesium adsorption in soils [PDF]

open access: yes, 2002
The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a ...

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.

Surface pre-coating of talc particles by carboxyl methyl cellulose adsorption : study of adsorption and consequences on surface properties and settling rate [PDF]

open access: yes, 2006
This paper investigates the adsorption of different sized carboxyl methyl cellulose (CMC) onto talc particles (adsorption isotherm, adsorption reversibility), its consequences on the particles properties (electrophoretic mobility and surface wetting) and

Kinetic selectivity in metal-organic framework chemical sensors

open access: yesNature Communications
Selective detection of specific volatile organic compounds (VOCs) is crucial for health, safety, and environmental applications, but current sensors suffer from poor selectivity and struggle to measure specific VOCs in the presence of interfering ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
