Effect of the Hydrophilic Block Length on the Micellar Properties of Oxyethylene-Oxybutylene Diblock Copolymers in Aqueous Solution: Density and Viscosity Studies

ABBAS KHAN; DURRANI, GULREZ FATIMA; MUHAMMAD USMAN; WAYNE HARRISON; MOHAMMAD SIDDIQ (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2009-10-20)

Density and viscosity measurements, over a wide range of concentration and temperature, were implied to investigate the effect of hydrophilic block length on the micellar properties of the aqueous solution of E40B8, EgoB8 ...
Identification of Radiation Treatment of Frozen Chicken and Fresh Turkey using DNA Comet Assay

KHAN, HASAN MAHMOOD; KHAN, ASHFAQ AHMAD (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2009-10-20)

DNA comet assay was applied to check the detection of radiation treatment of frozen chicken and fresh turkey. The cells from unirradiated and irradiated samples of chicken and turkey were extracted in cold PBS, embedded ...
Oxidation of CO by 02 over ZnO Studied by FTIR Spectroscopy

GHULAM HUSSAIN (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2009-10-20)

The adsorption of CO at room temperature on finely divided ZnO surfaces, studied by FTIR, shows reversible bands (2250-2050 cm-I) and irreversible absorption bands (1800-600 cm-I ). The irreversible absorption bands (1800-600 ...
Micellization of Dodecyl Benzenesulfonic Acid and its Interaction with Poly(Ethylene Oxide) Polymer

KHAN, MOHAMMAD SALEEM; ZARSHAD ALI (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2009-10-20)

The interaction between dodecyl benzene sulfonic acid (DBSA) with poly (ethylene oxide) (PEO) has been investigated at 293 K by conductance and surface tension measurements. The effect of concentration on the electrical ...
Surface Area and Pore Size Distribution of Activated Carbon Produced from Low Cost Precursors

SULTAN ALAM; BANGASH, FAZLULLAH KHAN (HEJ Research Institute of Chemistry, University of Karachi, Karachi., 2009-10-20)

Fast growing wood (Paulownia tomentosa-PT, Ailanthus altissima-AA, Salvadora oleoides-SO) and animal bones were utilized for the preparation of activated carbon. The carbon samples were activated by thermal means (400-10000C). ...
