We present a DSC and X-ray scattering study investigating the effect of polyhedral oligomeric silsesquioxane (POSS) block crystallinity on self-assembly poly(acryloisobutyl silsesquioxane)-b-poly(ethylene oxide)-b-poly(acryloisobutyl silsesquioxane) (POSS-PEO-POSS) triblock copolymer poly(ethylene oxide)-b- (PEO-POSS) diblock copolymers mixed with lithium bis(trifluoromethanesulfonyl)imide salt...

The kinetics of uptake of gaseous N2O5 on submicron aerosols containing NaCl and natural sea salt have been investigated in a flow reactor as a function of relative humidity (RH ) in the range 30–80% at 295±2 K and a total pressure of 1 bar. The measured uptake coefficients, γ , were larger on the aerosols containing sea salt compared to those of pure NaCl, and in both cases increased with incr...

We present a phase diagram of the nucleosome core particle (NCP) as a function of the monovalent salt concentration and applied osmotic pressure. Above a critical pressure, NCPs stack on top of each other to form columns that further organize into multiple columnar phases. An isotropic (and in some cases a nematic) phase of columns is observed in the moderate pressure range. Under higher pressu...

The effects of salinity on anaerobic waste degradation and microbial communities were investigated, in order to propose an appropriate leachate recirculation process in a waste landfill in a tropical region. A salt concentration of 21 mS cm-1 of electrical conductivity (EC) did not affect waste degradation, but a salt concentration of 35 mS cm-1 of EC inhibited CH4 generation. A higher salt con...

Solid polymer electrolytes have been prepared by solution casting technique. Carboxy methylcellulose (CMC)-ammonium nitrate (AN) films were studied with varied AN salt concentration from 5-50 wt.% at ambient temperature. X-ray diffraction (XRD) pattern shows the amorphous nature of polymer electrolyte samples. IR-spectra confirm the polymer-salt complexes in the range of 1633 829 cm -1 . Impeda...

This collaborative project addresses two key issues. The first is the need for Speech and Language Therapy (SALT) students to develop skills in analysis of a wide range of speech disorders and to apply these to clinical practice. The second is the lack of availability of instrumental analysis equipment in many SALT clinics. Telematic links between Queen Margaret University College (QMUC) and a ...

the aim of this work was to develop a new and simple coacervative extraction method for the preconcentration and spectrophotometric determination of cu(ii) in water samples. dithizone was used as the chelating agent while an anionic surfactant, namely sodium dodecyl sulfate (sds), was used as extracting agent at room temperature. central composite design (ccd) based on response surface methodol...

Objective (s): In light of misuse of antibiotics in animal husbandry and their side effects on human health, there is an argent need to develop simple and rapid methods for determining the quantification of antibiotics in biological systems. Materials and Methods: In this work a facile and ultrasensitive colorimetric aptasensor was reported for detection of oxytetracycline (OTC) in water and mi...

Rice is an important cereal crop responsible for world’s food security. The sensitivity of rice plants toward a range of abiotic stresses is a prime challenge for its overall growth and productivity. Among these, salinity is a major stress which results in a significant loss of global rice yield annually. For finding straightforward and strict future solutions in order to assure the food securi...
