In this research, modification on the ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentrations of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (...

Treatment of d(1) [(nacnac)TiCl(Ntol(2))] with NaN(3) results in NaCl formation and N(2) ejection to yield the first four coordinate, parent imide [(nacnac)Ti=NH(Ntol(2))] (nacnac(-)=[ArNC(CH(3))](2)CH, Ar = 2,6-iPr(2)C(6)H(3), tol = 4-CH(3)C(6)H(4)).

An iron(IV) tetrazene complex has been synthesized that is an important addition to a previously proposed catalytic aziridination cycle. It provides two key insights about the aziridination: an iron(IV) imide is formed and this imide can bind an additional ligand in the cis position.

A new kind of tetrahydro[5]helicene-based imide dyes with intense fluorescence and large Stokes shifts in both solution and solid state were developed and theoretically investigated.

In order to determine whether there is an orientation preference of pyrrole-imidazole (Py-Im) polyamide dimers with respect to the 5′-3′ direction of the backbone in the DNA helix, equilibrium association constants (Ka) were determined for a series of six-ring hairpin polyamides which differ with respect to substitution at the N and C termini. Affinity cleaving experiments using hairpin polyami...

In the title compound, C(12)H(13)NO(2), the dihedral angle between the benzene ring and the imide segment is 85.7 (1)°. In the crystal, the mol-ecules are packed into zigzag chains parallel to the a axis.

A rhodium(III)-based catalytic system has been used to develop a C−H bond activation of benzaldehyde derivatives and subsequent functionalization with dioxazolones in order afford imides. The importance the nature directing group perform selectively aldehydic highlighted. scope investigation showed that this transformation could be applied various many as well an acrolein derivative. Derivatiza...

Remarkable changes of properties result from systematically varying the surface functionality of polyamide dendrimers within a single generation.

In this work, polyamide (PA)/silica nanocomposite films prepared by dissolution method of composite mixing were investigated. The morphology of nanocomposite films were characterized using scanning electron microscope (SEM), reveals that nano silica powder were uniformly dispersed on PA silica nanocomposite film. Chemical composition of film was confirmed by Fourier transform infrared spectrosc...
