Lamellar membranes are attracting extensive attention for high throughput and precise molecules/ions sieve separation. However, the energy-consuming exfoliation and low yield of single-layer nanosheets restrict the massive production of membranes. Herein, we facilely fabricated 2D Ni-mediated metal-organic framework (Ni-MOF) membranes directly from …
The sieve tensioning device, NOVATENS, uses compressed air to ensure uniform tensioning of the sieve fabric in the sieve frame After attaching the clamps, it simultaneously tightens the sieve in the vertical and horizontal directions. Easy operation. The sieve tensioning device NOVATENS is easy to use. Only brief training is required to operate ...

Size selectivity is an important mechanism for molecular recognition based on the size difference between targets and non-targets. However, rational design of an artificial size-selective molecular recognition system for biological targets in living cells remains challenging. Herein, we construct a DNA molecular sieve for size-selective molecular recognition to improve the biosensing ...
More formally: sorts is a comma-delimited ordered list of property names to sort by. Adding a -before the name switches to sorting descendingly.; filters is a comma-delimited list of {Name}{Operator}{Value} where {Name} is the name …
The results suggest the incorporation of chromium into the molecular sieve framework for the CrAPSO-11 c 1997 Academic Press catalyst. ° INTRODUCTION The skeletal isomerization of n-butenes has been thoroughly studied on a variety of catalytic systems for over 30 years (1–7). Several reaction mechanisms as well as different reaction ...

Efficient Nova sieve cleaner The Nova cleaner, made of special synthetic material, tips on a central foot, between the sieve and the sieve tray. Thanks to the innovative design, one periferic foot is always on the sieve bottom and two brushes are on the sieve. This allows the sieve and the sieve tray to be intensively cleaned in every corner.
ABSTRACT Public key cryptography is based on two popular mathematical hard problems namely the integer factorization and discrete logarithm problem. Number Field Sieve (NFS) and Function Field Sieve (FFS) are the most efficient and widely used algorithms to solve integer factorization and discrete logarithm problems. The main phases of these algorithms are …

The invention discloses a catalyst in which La and V replace MCM-41 molecular sieve framework and a preparation method thereof. That is to add cetyltrimethylammonium bromide and 2mol/L sodium hydroxide solution into water, and slowly add orthosilicate ethyl ester, and then slowly add NH 4 VO with the same molar mass of metal V and La at the same time.

Structurally sound: The synthesis of AlPO4‐LTA zeolite in ionic liquids employs 1‐benzyl‐3‐methylimidazolium, tetramethylammonium, and fluoride ions for structuring α cages, sodalite cages, and cubes (see picture; C gray, N blue, O red, Al and P purple, F green). Selective removal of 1‐benzyl‐3‐methylimidazolium ions results in a stable AlPO4‐LTA molecular sieve.

Ga-MCM-22 with high gallium content has been synthesized with hydrothermal method and characterized by means of X-ray diffraction, SEM, TGA, 71Ga and 29Si MAS NMR, BET surface area, and NH3-TPD. Ga-MCM-22 was obtained as very homogeneous particles of about 5-7 μm diameters and showed very similar morphologies to its Al analogue. The Na/Ga ratio of Ga …
In this work, CO2 adsorption on a laboratory-synthesized polymeric copper(II) benzene-1,3,5-tricarboxylate (Cu-BTC) metal−organic framework was modeled by means of the semiempirical Sips equation in order to obtain parameters of engineering interest. Produced Cu-BTC samples were characterized by X-ray diffraction, thermogravimetry, and microporosimetric analysis; …
