The catalyst was synthesised using porous crystals called metal - organic frameworks which allow precise spatial control of the chemical elements.

Not exact matches

So a fundamental part of education is to expose such hidden or explicit purposes and presuppositions and critically examine them and transform them to a conscious commitment to a world - view which sees nature, humanity and cosmos within an organic life system working within an ultimate framework of a spiritual movement of self - determining selves towards a community of justice and love.

We need a science and technology reinterpreted within a new framework which takes the organic and spiritual dimensions of reality seriously along with the mechanical.

The researchers focused on a hybrid membrane that is part polymer and part metal - organic framework, which is a porous three - dimensional crystal with a large internal surface area that can absorb enormous quantities of molecules.

When that happens, the hybrid membrane switches from having a single channel to transport carbon dioxide, in which the molecules must go through the polymer, to two channels, in which the molecules can either move through the polymer or through the metal - organic framework highways.

They belong to a family of versatile porous materials called metal organic frameworks, which have a wide variety of other potential applications.

To gain this new understanding into the behavior of matter at the nanoscale, García - Garibay's research group designed three rotating nanomaterials known as MOFs, or metal - organic frameworks, which they call UCLA - R1, UCLA - R2 and UCLA - R3 (the «r» stands for rotor).

Shen et al. grew ordered arrays of microcrystals of the ZIF - 8 metal - organic framework, in which zinc ions are bridged by 2 - methylimidazole linkers, inside a porous polystyrene template.

Known for their exceptional porosity that enables the trapping or transport of molecules, metal - organic frameworks (MOFs) take the form of a powder, which makes them difficult to format.

The findings, published in the journal Science, show that materials called metal - organic frameworks (MOFs) can effectively remove the contaminant acetylene from ethylene, the material from which much of the world's plastic is made.

In the crystal developed by UCLA researchers, a metallo - organic framework (top and bottom layers of molecules) surrounds central sphere - like shapes, which can rotate at up to 50 billion rotations per second.

An international collaboration of scientists led by Omar Yaghi, a chemist with the Lawrence Berkeley National Laboratory (Berkeley Lab), has developed a technique they dubbed «gas adsorption crystallography» that provides a new way to study the process by which metal - organic frameworks (MOFs)-- 3D crystals with extraordinarily large internal surface areas — are able to store immense volumes of gases such a carbon dioxide, hydrogen and methane.

Kitagawa described how porous coordination polymers (PCPs) / metal - organic frameworks (MOFs) have been found to be able to store large volumes of gases, which has in turn sparked studies around the world on the mass storage of carbon dioxide and methane.

One solution has been to exfoliate covalent organic frameworks (COFs), which are crystalline porous polymers.

A. Dieter Schlüter of the Swiss Federal Institute of Technology (ETH), Zurich, demonstrated a different approach and applied it to a related material — metal organic frameworks (MOFs), which are porous crystalline materials composed of metal ions joined by organic linkers.

Instead, membrane separation and metal - organic framework capture technologies, which are showing promise in the lab, could meet the performance criteria for a scalable CCS solution.

The most popular feature of Maritime Law Book's law report series was the use of Key Numbers which combines the best features of the Canadian Abridgement Classification System (Key Words providing a framework to organic cases by legal concepts, minus the associated cumbersome alphanumeric numbering scheme) with a numbering scheme modelled on the West Key Numbering System.
