Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...

We describe a spectroelectrochemical approach to accelerated electrochemical stability studies of conjugated polymers under oxidative stress. The polaron stabilities of alternating copolymers based on (i) thiophene and thiazole, namely PTTz, and (ii) bithiophene and thiazole, namely PTTTz, are compared in neat films with that of P3HT. P3HT is found to be the most stable whilst PTTz is found to ...

We have performed femtosecond studies of electron solvation in a series of neat linear alcohols. The measured formation time of the solvated electron is consistent with previous studies using solutes. The major character of electron solvation, i.e. the two-state character, is evidenced by the finding of an approximate isosbestic wavelength for methanol at 750 nm. Isotope effects for CH3OH, CH30...

The OH stretch line shape of ice Ih exhibits distinct peaks, the assignment of which remains controversial. We address this longstanding question using two dimensional infrared (2D IR) spectroscopy of the OH stretch of H2O and the OD stretch of D2O of ice Ih at T=80 K. The isotropic response is dominated by a 2D line shape component which does not depend on the pump pulse frequency. The decay t...

The structural and molecular mechanism of double-stranded DNA (dsDNA) and single-stranded DNA (ssDNA) solvation in ten room-temperature ionic liquids (RTILs) is disclosed herein. We show that the Drew Dickerson B DNA structure solvated in neat RTILs based on imidazolium, oxazolium, pyrrolidinium, pyrimidinium and quaternary ammonium cations, combined with hexafluorophosphate and tetrafluorobrom...
