Thermodynamic Considerations of Microgel Swelling Behavior

Autor: John C. Mitchell, Louise Gracia, B. Z. Chowdhry, Anthony E. Beezer, V.T. Pinkrah, Martin J. Snowden

Publikováno v: Langmuir. 20:8531-8536

A simple but novel thermodynamic model is presented, based upon van't Hoff analysis, for the reversible swelling behavior of colloidal microgels. The swelling, as a function of temperature, of poly(N-isopropylacrylamide/N,N'-methylenebisacrylamide) a

Effect of Sodium Chloride upon Micellization and Phase Separation Transitions in Aqueous Solutions of Triblock Copolymers: A High-Sensitivity Differential Scanning Calorimetry Study

Autor: B. Z. Chowdhry, Jonathan K. Armstrong, Martin J. Snowden, Stephen A. Leharne

Publikováno v: Langmuir. 14:2004-2010

The effect of sodium chloride upon the thermally induced transitions in aqueous solutions, of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (PEO−PPO−PEO) copolymers, has been investigated using high-sensitivity diffe

Thermodynamic Model Fitting of the Calorimetric Output Obtained for Aqueous Solutions of Oxyethylene− Oxypropylene−Oxyethylene Triblock Copolymers

Autor: Iain F. Paterson, Stephen A. Leharne, Jonathan K. Armstrong, B. Z. Chowdhry

Publikováno v: Langmuir. 13:2219-2226

A high-sensitivity differential scanning calorimetry (HSDSC) study of aggregation transitions in dilute aqueous solutions of oxyethylene−oxypropylene−oxyethylene (EO−PO−EO) triblock copolymers (poloxamers) is reported. The data have been anal

PGSE-NMR studies of solvent diffusion in poly(N-isopropylacrylamide) colloidal microgels

Autor: Peter Stilbs, B. Z. Chowdhry, Peter C. Griffiths, Martin J. Snowden

Publikováno v: Colloid and Polymer Science. 273:405-411

The solvent self-diffusion coefficient has been studied in thermoshrinking poly(N-isopropyl acrylamide) microgel dispersions by the pulsed-gradient spin-echo PGSE-NMR technique, as a function of temperature and mass fraction. After suitable correctio

An Investigation of Dilute Aqueous Solution Behavior of Poly(oxyethylene) + Poly(oxypropylene) + Poly(oxyethylene) Block Copolymers

Autor: B. Z. Chowdhry, John C. Mitchell, M. S. Tute, Jonathan K. Armstrong, D. O. Smith, Watson Loh, Paul G. Royall, Stephen A. Leharne, Anthony E. Beezer

Publikováno v: Langmuir. 10:4001-4005

Dilute solution phase scanning microcalorimetric transition data for 27 members of the pluronic ABA block copolymer family are presented. Analysis of these data suggest a correlation between thermodynamic parameters for the observed transitions and p

A survey of metal levels in street dusts in an inner London neighbourhood

Autor: Stephen A. Leharne, B. Z. Chowdhry, David Charlesworth

Publikováno v: Environment International, Vol 18, Iss 3, Pp 263-270 (1992)

Dust samples were collected from various roads situated in the Globetown Neighbourhood area of East London. The samples were analyzed for lead, copper, nickel, manganese, iron, and aluminium by flame atomic absorption spectroscopy. The results indica
