Chemical sensors based on swellable molecularly imprinted polymer microspheres in a hydrogel
… poly (N-isopropylacrylamide-acrylic acid) (poly NIPA-AAc) particles by suspension polymerization in a perfluorocarbon solvent using ultrasonic emulsion technique. The particles were crosslinked with 5% of N, N'-methlene-bis-acylamide (MBA) using 20% fluorinated surfactant as a stabilizer. The …

Polymer Gels: Kinetics, Dynamics Studies and Their Applications as Biomaterials
… spinodal decomposition of N-isopropylacrylamide (NIPA) polymer gel is investigated using turbidity and ultrasonic techniques. By probing movement of domains, a possible time-dependent gel structure in the spinodal decomposition region is presented. Theoretical studies of solution convection in gel …

Thermally responsive polymers and their applications
… We chose poly(N-isopropylacrylamide) (polyNIPA) as a platform, which phase-separates from water upon heating. The thermally responsive properties and applications of polyNIPA are introduced in Chapter One. In Chapter Two, we described the synthesis of polyNIPA gels with an imidazole …

Evaluating bacterial cell immobilization matrices for use in a biosensor
… alginate beads. The thermally reversible gel, NIPA-co-AAc (N-isopropylacrylamide-co-acrylic acid), shows promise as an immobilization matrix for the bacteria; however its high lower critical solution temperature (LCST) of ~33oC is problematic for typical, ambient applications. Another thermally …

Computational Studies of Protonated Cyclic Ethers and Benzylic Organolithium Compounds
Protonated epoxides feature prominently in organic chemistry as reactive intermediates. Gas-phase calculations studying the structure and ring-opening energetics of protonated ethylene oxide, propylene oxide and 2-methyl-1,2-epoxypropane were performed at the B3LYP and MP2 levels (both with the …

I The synthesis and coordination chemistry of novel 1,1,1-tris(aminomethyl)ethane (TAME) derived ligands and their use as size selective fluorescent zinc(II) sensors II The synthesis of strongly and weakly binding ligands with nitrogen, oxygen, and sulfur-donor groups to be used as receptors in fluorescent ratiometric indicators for transition metal ions
… networks built from N-isopropylacrylamide (NIPA) have been prepared toward the sensing of Cu(II). The candidate's role in this collaborative project was to synthesize strongly and weakly binding metal ion receptors to be copolymerized into the polyNIPA network. Fluorescent groups were also …

The Impact of Ethnicity on Maternal Health Outcomes and Mental Well-being: A Focus on Ethnic Minorities in the UK
Background: Ethnic minority women experience significantly higher maternal health issues and mental well-being outcome in the UK. Studies indicates that women from Black, Asian, and others ethnic communities suffer from maternal mortality, severe morbidity, and mental health conditions. This …
