Metal-Organic Frameworks For Adsorption Driven Energy Transformation: From Fundamentals To Applications

A novel class of materials, i.e. Metal-Organic Frameworks (MOFs), has successfully been developed that is extremely suited for application in heat pumps and chillers. They have a superior performance over commercial sorbents and may potentially contribute to considerable energy savings worldwide. Globally about 33 % of the energy consumption is...

Electron beam irradiation of dimethyl-(acetylacetonate) gold(III) adsorbed onto solid substrates

Electron beam induced deposition of organometallic precursors has emerged as an effective and versatile method for creating two-dimensional and three-dimensional metal-containing nanostructures. However, to improve the properties and optimize the chemical composition of nanostructures deposited in this way, the electron stimulated decomposition...

Hydrogen mediated transport of Sn to Ru film surface

The authors report on the interaction of atomic hydrogen with Sn and thin Ru film at room temperature. The study is done using a combination of photoelectron and low energy ion scattering spectroscopies as well as scanning electron microscopy. The adsorption of hydrogen on a Sn surface leads to the formation of stannane (SnH4), which...

On the Beneficial Role of Silicon to Organisms: A Case Study on the Importance of Silicon Chemistry to Metal Accumulation in Yeast

Silicon is involved in numerous important structural and functional roles in a wide range of organisms, including diatoms, plants, and humans, but clear mechanisms have been discovered only in diatoms and sponges. Silicate availability influences metal concentrations within various cell- and tissue-types, but a mechanism has not been discovered...

Diffusion and adsorption of linear and branched alkanes in zeolites

Branched hydrocarbons are preferred to linear hydrocarbons as ingredients in petrol, as they enhance the fuel octane number. By catalytic isomerisation linear hydrocarbons are converted into branched hydrocarbons, then it becomes necessary to separate the mixture. A variety of zeolites may be used for this purpose, either on thermodynamics or...

Opportunities and limitations of hydrogen storage in zeolitic clathrates

The feasibility of using zeolites, and more specifically the clathrasil subgroup, for hydrogen storage has been investigated by comparing their H2 loading rate and storage capacity to the technically required values. The uptake rate and capacity are determined by means of computational modelling for a large number of clathrasil structures. It...

Poisson–Boltzmann theory of the charge-induced adsorption of semi-flexible polyelectrolytes

A model is suggested for the structure of an adsorbed layer of a highly charged semi-flexible polyelectrolyte on a weakly charged surface of opposite charge sign. The adsorbed phase is thin, owing to the effective reversal of the charge sign of the surface upon adsorption, and ordered, owing to the high surface density of polyelectrolyte strands...
