Zeolites: Large molecules welcome.
Many eff orts to improve the performance of heterogeneous catalysts and adsorbents focus on creating materials that are highly active and selective for their target reactants and products. Th is typically involves the use of porous solids with high surface areas, for instance crystalline or amorphous inorganic compounds, whose diff usional access, adsorption, and reaction properties depend stro...
متن کاملMicrodialysis sampling method for evaluation of binding kinetics of small molecules to macromolecules.
Here we present an application of microdialysis sampling for evaluation of the binding kinetics of small molecules to macromolecules. It is label-free, and no immobilization of any interaction partner is required. The method was established by the coupling of a binding reaction with a membrane transport in a miniature and dynamic microdialysis sampling system. A theoretical model was establishe...
متن کاملLarge aqueous aluminum hydroxide molecules.
One of the first subjects introduced to students of environmental chemistry is the aqueous chemistry of aluminum. This metal is the third most abundant element in the shallow Earth, where it hydrolyzes in water to produce a rich array of solute molecules and solids, including clays and aluminum hydroxide phases. Although these materials are ubiquitous, we are just beginning to understand the ki...
متن کاملQuantum interference of large organic molecules
The wave nature of matter is a key ingredient of quantum physics and yet it defies our classical intuition. First proposed by Louis de Broglie a century ago, it has since been confirmed with a variety of particles from electrons up to molecules. Here we demonstrate new high-contrast quantum experiments with large and massive tailor-made organic molecules in a near-field interferometer. Our expe...
متن کاملPredicting the sizes of large RNA molecules.
We present a theory of the dependence on sequence of the three-dimensional size of large single-stranded (ss) RNA molecules. The work is motivated by the fact that the genomes of many viruses are large ssRNA molecules-often several thousand nucleotides long-and that these RNAs are spontaneously packaged into small rigid protein shells. We argue that there has been evolutionary pressure for the ...
