Polymers from β-(p-Hydroxyphenyl)propionitrile

From Commodity Polymers to Functional Polymers

Functional polymers bear specified chemical groups, and have specified physical, chemical, biological, pharmacological, or other uses. To adjust the properties while keeping material usage low, a method for direct synthesis of functional polymers is indispensable. Here we show that various functional polymers can be synthesized by in situ cross-linked polymerization/copolymerization. We demonst...

Vibrational properties of ferroelectric β-vinylidene fluoride polymers and oligomers

Nanoparticles from renewable polymers

The use of polymers from natural resources can bring many benefits for novel polymeric nanoparticle systems. Such polymers have a variety of beneficial properties such as biodegradability and biocompatibility, they are readily available on large scale and at low cost. As the amount of fossil fuels decrease, their application becomes more interesting even if characterization is in many cases mor...

detection of ampc-β-lactamases producing isolates among carbapenem resistant p. aeruginosa isolated from burn patient.

background  and  objectives: pseudomonas  aeruginosa is responsible for devastating nosocomial infections among severely burn patients. class c of cephalosporinase (ampc-β-lactamases) is important cause of multiple β-lactam resistance in p. aeruginosa . the aim of this study was to detect the ampc-β-lactamases producing isolates among carbapenem resistant p.  aeruginosa isolated from burn patie...

Synthesis and coordination behaviors of P-stereogenic polymers.

Optically active polymers containing P-stereogenic bisphosphine and 1,2,3-triazole units in the main chain were obtained by copper-catalyzed Huisgen cycloaddition. The repeating unit of the polymer adopted bidentate as well as tetradentate coordination, leading to the change in the conformations of the polymer via complexation with transition metals.
