Polyamide denture base materials are more flexible than the commonly used poly (methyl methacrylate) (PMMA). However polishability of polyamides has not been examined adequately. This study investigated the surface roughness (Ra) and clinical acceptability of samples of a polyamide denture base material and PMMA fabricated by injection moulding and traditional heat processing systems, respectiv...

We investigate the pretilt characteristics of a nematic liquid crystal [LC] in terms of ion beam exposure conditions on the homeotropic polyimide alignment layer. The pretilt angle of LCs in the case of high-energy ion beam treatment was decreased considerably almost the same to that of the homogenous alignment layer though we used homeotropic polyimide film at first. Increasing irradiating ene...

In the title compound, [Li(2)(CF(3)SO(2)NSO(2)CF(3))(2)(CH(3)CN)(2)](n), two Li(+) cations reside on crystallographic inversion centers, each coordinated by six O atoms from bis(trifluoromethanesulfonyl)imide (TFSI(-)) anions. The third Li(+) cation on a general position is four-coordinated by two anion O atoms and two N atoms from acetonitrile mol-ecules in a tetra-hedral geometry.

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 (...

A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types have been isolated and fully characterized. The aryl substituent that proved most useful in stabilizing the Ni(III)-imide moiety was the bulky 2,6...

Fabricating efficient perovskite solar cells on steel substrates could enable easy building integration of this photovoltaic technology. Herein, an n–i–p cell is developed for top illumination. The optimized stack uses a Ti bottom electrode, covered with indium tin oxide (ITO) interlayer and SnO2 electron transport layer passivated by [6,6]-phenyl-C61-butyric acid. active triple-cation perovski...

BACKGROUND Repetitive endothelial damage from dialysis membrane incompatibility is a probable cause of accelerated atherosclerosis in haemodialysis patients. Consequently pulse wave velocity (PWV), a measure of arterial stiffness, was utilized as a surrogate marker of vascular dysfunction during dialysis with two commonly used synthetic dialysers. METHODS PWV was monitored before, during and ...

The zinc finger protein EVI1 is causally associated with acute myeloid leukemogenesis, and inhibition of its function with a small molecule therapeutic may provide effective therapy for EVI1-expressing leukemias. In this paper we describe the development of a pyrrole-imidazole polyamide to specifically block EVI1 binding to DNA. We first identify essential domains for leukemogenesis through str...

Organosilanes bearing a phosphine imide moiety were synthesized and crystallographically characterized. Reaction of the pentacoordinated hydrodiphenylsilyl derivative with water gave [2-(diphenylphosphino)phenyl]diphenylsilanol accompanied by both reduction of the phosphine imide moiety and hydrolytic oxidation of the Si-H moiety.

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.
