Structural and Textural Properties of Al/Cu- and Al/Zn-Pillared Clays for Ethanol Conversion
A montmorillonite sample was pillared using mixed solutions of Al/Cu and Al/Zn as the pillaring agent. Al/Cu- and Al/Zn-pillared clays were applied in an ethanol conversion reaction.

Separation of steranes and hopanes by domestic X-type molecular sieves
Domestic 10X-type and 13X-type molecular sieves were used for the adsorption and desorption experiments of steranes and hopanes, and their stable carbon isotopic fractionation by the two kinds of molecular sieves during separation process was discussed ...

FUNCTIONAL PEARL : lazy wheel sieves and spirals of primes [PDF]
The popular method of enumerating the primes is the Sieve of Eratosthenes. It can be programmed very neatly in a lazy functional language, but runs rather slowly.

Molecular sieves control contamination and and insulate in thermal regenerators - A concept [PDF]
Zeolitic molecular sieves prolong the lives of cryogenic engines by preventing contamination of the thermal regenerators on the cold ends of closed-cycle engines. Sieves also serve as thermal insulators by preventing conduction of heat along regenerators

ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Graphene-like Membranes: From Impermeable to Selective Sieves
Recently, it was proposed that graphene membranes could act as impermeable atomic structures to standard gases. For some other applications, a higher level of porosity is needed, and the so-called Porous Graphene (PG) and Biphenylene Carbon (BPC ...

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
