FTIR AND NMR STUDIES OF ADSORBED CETHYLTRIMETHYLAMMONIUM CHLORIDE IN MCM-41 MATERIALS
The high use of surface-active agents (surfactants) by industry and households today leads to environmental pollution, therefore treatments are required to remove such substances from the environment.

Understanding the Effect of Calcination Process on the Mesoporous MCM-41 Material Morphology
The pore structure, which is known to be affected by calcination, is one of the desired features for materials especially when considered to be catalysts.

The mesoporous silica modified by salicylaldimine was prepared through a co-condensation method. Through the bridge effect from metal ion (copper ion, zinc ion, manganese ion), the model drug-avermectin was supported on the metal-Schiff base ...

CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

Adsorption of Sr2+ by MCM-41 Functionalized by Aminosilane Group [PDF]
In this research, MCM-41 molecular sieve was synthesized, and was characterized by XRD, FT-IR, TG and BET techniques. The ability of the adsorbent towards Sr2+ was then investigated.

Al‐Cu intermetallic compounds (IMCs) have a significant influence on the properties of Al‐Cu bimetallic interfaces formed in compound casting. This article provides a deeper understanding of microstructure, crystallography, thermal properties, hardness, and corrosion response of Al‐Cu IMCs with the goal of facilitating the optimization of the ...

Novedoso método para preparar materiales nanoporosos compuestos MFI/MCM-41 a partir de caolín venezolano. Efecto de la concentración de NaOH [PDF]
A MFI/MCM-41 composite material, a zeolite type MFI and Al-MCM-41 were synthesized from kaolin, using TPA and CTAB as structure directing agents. The MFI/MCM-41 composite material was synthesized in two steps.

The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Biogenic Silica from Rice Husk Ash - Sustainable Sources for the Synthesis of Value Added Silica
Ordered mesoporous silica with two dimensional MCM-41 or three dimensional MCM-48 pore structure are prepared via pseudomorphic transformation. Rice husk ash (RHA) with high purity was used as silica source for the first time.
