This paper reports on the thermodynamics through mapping out temperature–concentration phase diagrams and molecular structure morphology of binary organogels prepared with trisamide triarylamine (TATA) in tetrachloroethane their ternary thermoreversible hybrid gels formed polyvinyl chloride (PVC). For low PVC contents, TATA organogel moiety behaves as systems, while for higher thermal behavior ...

Carbonic anhydrase IX (CA IX) is currently generating great interest as a marker of tumour hypoxia and a potential chemotherapeutic target. In order to test the principle that a CA IX inhibitor could be used for targeting PET or SPECT metallic radioisotopes to tumours we have prepared a number of conjugates involving aryl-sulfonamides or an acetazolamide derivative linked to a range of copper, ...

Abstract The cobalt‐catalyzed reaction between 1,3‐dithiolanes and Grignard reagents, for the efficient synthesis of multi‐substituted alkene products, is described. method was applicable to a variety benzylic dithiolane substrates, affording di‐, tri‐, tetra‐substituted 1,1‐diaryl products in good excellent yields. use reagents with aryl aldehyde‐derived enabled access natural product‐derived ...

In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

some n¬-acyl-n'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. the structures of synthesized compounds have been characterized by ir, 1hnmr spectral studies. the synthesized compounds 5(a-f) have been screened for antibacterial activity. the effect of the structure of the investigated compounds on the antibacterial ...

Transforming C(sp3)–H bonds efficiently and selectively into C(sp3)–C(sp3) or C(sp3)–X is a highly relevant task. The direct arylation of allylic provides an elegant method for the formation unconjugated aryl-substituted olefins. Although both ionic- radical-based transition metal catalysis has been applied to achieve this transformation, numerous challenges remain. requirement persistent radic...
