Well-defined diblock copolymers of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid oxiranylmethyl ester, having both anchoring and steric stabilizing blocks in a 1:1 ratio, have been prepared by ringopening metathesis polymerization (ROMP). The epoxy-containing block copolymer stabilized in situ generated iron oxide (γ-Fe2O3) nanoparticles. The epoxy ester group provided strong chelation between the...

With an increase in the use of carbon fiber composites aerospace and automobile industry a collateral issue what to do with end-of-life has risen. In this study, we successfully developed second-generation composite using heterogenous mixture thermoset thermoplastic recycled (CFCs). The recovered vinyl ester epoxy CFCs (thermosets) were characterized thermogravimetric analysis. Adhesive perform...

Juvenile hormone (JH) undergoes metabolic degradation by two major pathways involving JH esterase and JH epoxide hydrolase (EH). While considerable effort has been focussed on the study of JH esterase and the development of inhibitors for this enzyme, much less has been reported on the study of JH-EH. In this work, the asymmetric synthesis of two classes of inhibitors of recombinant JH-EH from ...

Natural resources in general and plant materials in particular are receiving more attention due to their safety as pharmaceutical excipients. Present work assessed the combination potential of natural hydrophobic resin, rosin, and synthetic polymer ethyl cellulose to mask the abhorrent inherent taste of ambroxol hydrochloride, by microencapsulation technique, and its possibility to formulate as...

A cyanate ester/microcapsule system with low cure temperature and self-healing " Abstract: Microcapsules filled with epoxy resin were blended into cyanate ester resin to produce systems with low cure temperature and self-healing capacity. A 4,4′-diaminodiphenylsulfone (DDS) curing agent was adopted for the systems. The mechanical properties, thermal stability and self-healing ability of the sys...

Natural polymers are widely used in pharmaceutical formulations. They are biodegradable and generally nontoxic in nature. In this review pharmaceutical application of rosin is characterized. Rosin is a natural non-volatile resinous mass obtained from Pinus palustris. Physico-chemical characteristics and ease of availability of rosin provide a platform to use it as a polymer for different drug d...
