Conventional ion implantation has been shown to modify the surface properties of polymers such as their hardness, conductivity, and biocompatibility. In this study, poly(bisphenol A carbonate) (PC) films were implanted by Ar+ ions with an energy level of 100 keV in order to improve their biocomp...

The thermal decomposition of poly(bisphenol A carbonate) (PoC) results in the formation of the endocrine disruptor bisphenol A (BPA). In the present work, we investigated the kinetics of the thermal decomposition of PoC, and the subsequent decomposition of BPA, under pyrolysis conditions and in ...

The effect of prepolymer crystallinity on the solid-state polymerization (SSP) of poly(bisphenol A carbonate) was examined using nitrogen as a sweep fluid. A low-molecular-weight prepolymer was synthesized by melt transesterification and prepolymers with different crystallinities (11.7%, 23.3%, ...

Poly(bisphenol A carbonate) or polycarbonate (PC) constitutes a significant fraction of the Waste Electrical and Electronic Equipment, mainly due to its high production and consumption rate and its variety of applications. Traditional methods for its treatment no longer appear to provide long-te...

Recycling of polymer wastes is an important way for recovering valuable chemicals and reducing the environmental impact of human activities. The increasing amount of poly-bisphenol A carbonate (PC) wastes generated by electronical and electrical equipments, automobiles, optical materials, CDs an...

Suspensions of poly(bisphenol A carbonate) (PBAC) nanoparticles of varying size and shape have been produced by ablation of a PBAC target in liquid media with the fourth harmonic of a Q-switched Nd:YAG laser (wavelength 266 nm, full width at half maximum 4 ns, repetition rate 10 Hz). The polymer...

Chemical degradation of poly (bisphenol A carbonate) is achieved using an easy-to-use organocatalyst, TBD (1,5,7-triazabicyclo [4.4.0]-dec-5-ene). Because of increased concern over bisphenol A (BPA) acting as a potent hormone disruptor, proper disposal of end-of-life poly (bisphenol A carbonate)...

Synthesised vanadium-coordinated N,N-bis(o-hydroxybenzaldehyde)phenylene diamine catalyst, [VO(sal-HBPD)] and supported catalyst, p[VO(sal-HBPD)] were employed for the oxidation of quinoline. The use of [VO(sal-HBPD)] and p[VO(sal-HBPD)] for the oxidation of quinoline, (Quinoline-to-H2O2 ratio 1...

Nucleoside triphosphate diphosphohydrolases (NTPDases), an important class of ectonucleotidases, are responsible for the sequential hydrolysis of extracellular nucleotides. However, over-expression of NTPDases has been linked with various pathological diseases e.g. cancer. Thus, to treat these d...

A series of new quinoline derivatives was designed, synthesized and evaluated for their antiproliferative activity. The results demonstrated that compounds 11p, 11s, 11v, 11x and 11y exhibited potent antiproliferative activity with IC50 value of lower than 10 μM against seven human tumor cell l...

New quinoline-3-carbonitrile derivatives were synthesized and evaluated for their potential antibacterial behavior. Compounds were obtained by a one-pot multicomponent reaction of appropriate aldehyde, ethyl cyanoacetate, 6-methoxy-1,2,3,4-tetrahydro-naphthalin-1-one and ammonium acetate. Struct...

New D-π-A type quinoline derivatives (CbzVQ and TPAVQ) were synthesized via Knoevenagel condensation reactions. They exhibited reversible high-contrast mechanofluorochromic (MFC) behavior under grinding/fuming treatment. Taking CbzVQ as an example, its fluorescence could be switched from blue t...

The quinoline core possesses a vast number of biological activities such as anticancer, antimalarial, antimicrobial, antifungal, antitubercular and antileishmanial. The conventional classical synthetic methods require the use of expensive and harsh conditions such as high temperature. Currently ...

Quinolines and thiazolopyridines were developed as allosteric inhibitors of MALT1, with good cellular potency and exquisite selectivity. Mouse pharmacokinetic (PK) profiling showed these to have low in vivo clearance, and moderate oral exposure. The thiazolopyridines were less lipophilic than th...

Bacterial infections, caused predominately by Gram-positive and Gram-negative organisms, are proliferation of harmful strains of bacteria on or inside the body. Hospital-acquired and community-acquired bacterial infections have already put a heavy burden on the global health system. Antibiotics ...

A series of novel derivatives of the 1,3-tropolone (β-tropolone) system—2-(2-quinolyl)-5,6,7-trichloro-1,3-tropolones and 2-(2-quinolyl)-4,5,6,7-tetrachloro-1,3-tropolones have been prepared by the acid-catalyzed reaction of 2-methylquinolines with 3,4,5,6-tetrachloro-1,2-benzoquinone. The mol...
