Among the methods available to reduce water production, injecting a gelling system composed of a polymer and a crosslinker has been widely used. In this work, a hydrogel was prepared by crosslinking of an aqueous solution containing hexamethylenetetramine (HMTA) as crosslinker, hydrochloric acid (HCl) as an activator, and the co-polymer of 2-acrylamido-2methyl-propanesulfonic-acid sodium salt (...

The rational design and facile construction of hybrid metal–organic framework (MOF) with hierarchical nanostructures can motivate novel multifunctional platforms to attain desirable performance. In this work, a new series MOF-on-MOF heterostructures, including ZIF-8/Zinc(II)-hexamethylenetetramine (ZIF-8/Zn-HMT) ZIF-8 + ZIF-67/Zn-HMT-X (ZIF/Zn-HMT-X), be conveniently synthesized by heteroepitax...

In this work, we report on the synthesis of nitrogen doped SrTiO3 nanoparticles with efficient visible light driven photocatalytic activity toward Cr(VI) by the solvothermal method. The samples are carefully characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis diffuse reflectance spectroscopy and photocatalytic test. It is found that nitroge...

Neutral (salicylaldiminato)nickel(II) methyl complexes [{6-C(H)dNAr-2,4-I2C6H2O-κN,O}NiMe(L)] (Ar ) 2,6-{3,5-(F3C)2C6H3}2C6H3) with different water-soluble ligands L (2a, L ) 1,3,5-triaza-7phosphaadamantane; 2b, L ) hexamethylenetetramine (urotropine); 2c, L ) tetraethylammonium pyridine3-sulfonate; 2d, L ) amino-terminated poly(ethylene glycol) monomethoxy ether) were prepared. 2a-d are potent...

Healthy subjects ingested 2H2O and after 14, 22, and 42 h of fasting the enrichments of deuterium in the hydrogens bound to carbons 2, 5, and 6 of blood glucose and in body water were determined. The hydrogens bound to the carbons were isolated in formaldehyde which was converted to hexamethylenetetramine for assay. Enrichment of the deuterium bound to carbon 5 of glucose to that in water or to...

In this study, we prepared a mesoporous carbon with hexagonally packed mesopores through evaporation-induced self-assembly (EISA)—with the diblock copolymer poly(ethylene oxide-b-ε-caprolactone) (PEO-b-PCL) as the template (EO114CL84), phenolic resin as the carbon precursor, hexamethylenetetramine (HMTA) as the curing agent, and star octakis-PEO-functionalized polyhedral oligomeric silsesquioxa...
