This work investigates the movement of anions during potentiostatic controlled reduction of novel composite materials consisting of high surface area cellulose substrates, extracted from the Cladophora sp. algae, coated with thin ( approximately 50 nm) layers of the intrinsically conducting polymer (ICP) polypyrrole. The coating was achieved by chemical polymerization of pyrrole on the cellulos...

In this study, we evaluated hydrodynamic chromatography (HDC) coupled with inductively coupled plasma mass spectrometry (ICP-MS) for the analysis of nanoparticles in environmental samples. Using two commercially available columns (Polymer Labs-PDSA type 1 and 2), a set of well characterised calibrants and a new external time marking method, we showed that flow rate and eluent composition have f...

To evaluate the concentration of naturally occurring radioactive material particularly, uranium concentration in fly ash, samples were collected from Guru Nanak Dev Thermal Plant, Bathinda, Punjab, India and Suratgarh Super Thermal Power Station, Suratgarh, Rajasthan, India during 2010 to 2012. Samples were processed using ICP-MS (Inductively coupled plasma – mass spectrometry) with multi-eleme...

Recent studies have suggested that under certain conditions, inhalation of stable xenon can cause an increase in CBF or intracranial pressure (ICP). We reviewed the ICP changes that occurred during 48 stable xenon/CT CBF studies in 23 comatose head-injured patients to determine if the concentration (32%) and duration of inhalation (4.5 min) of stable xenon we used caused an increase in ICP. In ...

Antiferroelectrics (AFE) can exhibit a “shape memory function controllable by electric field”, with huge isotropic volumetric expansion (0.26%) associated with the AFE to Ferroelectric (FE) phase transformation. Small inverse electric field application can realize the original AFE phase. The response speed is quick (2.5 ms). In the Pb0.99Nb0.02[(Zr0.6Sn0.4)1-yTiy]0.98O3 (PNZST) system, the shap...
