In a first paper published in Nature Communications, researchers demonstrate that unlike a kitchen sieve, these three dimensional molecular sieves can change their pore shape and their flexibility ...

Sieves can be used in stacks with different mesh sizes, to divide samples into various size fractions and hence determine particle size distributions. Sieves and screens are usually used for larger ...

Molecular Sieves The zeolite minerals, whose crystals contain a myriad of minute pores, have made possible a new branch of chemical technology. They can perform precise separations of very similar ...

Knowing the plants of Saudi Aramco well and being in charge of product management of CECA SILIPORITE molecular sieves, I would like to comment on the article by Ahmed Ghazal (“Common errors can ...

Molecular sieves are highly porous materials that have the ability to adsorb molecules based on size and shape. They are commonly used as desiccants (absorbing moisture) or as adsorbents for various ...

Future large space-based telescopes could benefit from photon sieves containing trillions of holes to gather and focus light. Diffractive optical elements known as photon sieves could be ideal for use ...
