Modified glycol chitosan nanocarriers carry hydrophobic materials into tumours

Raza A., de-la Fuente M., Uchegbu I.F., Schätzlein A., Nuclear Medicines Oncology & Radiotherapy Institute, PK

Etoposide is a potent anticancer drug commonly used in a variety of malignancies. High protein binding, requirement of fairly high doses of drugs to achieve sustained plasma levels and hypersensitivty issues are related to its [...]

The Effects of Gamma rays on P-channel MOSFET

Iqbal M.A., Firdous U., Punjab University, PK

The effect of Gamma rays on PMOS is studied. The range of Gamma rays used from 1M.rad to 3M.rad. The device is exposed by gamma radiation and observes its parameters as threshold voltage, trans-conductance and [...]

Effect of temperature and γ rays radiation on the electrical and optical characteristics of Quantum well structure based laser diode

Iqbal M.A., Ghani S., Punjab University, PK

Analysis of effect of temperature in the range (280k-300k) and radiation (X-rays and γ rays) on the AlGaInP based laser at 665nm emission wavelength has been carried out. Before and after irradiation, current-voltage (I-V), light-current [...]

Catalytic Degradation of Substituted Phenols in Water by Chemically Synthesized Bimetallic Nanoalloys

Nazir R., Mazhar M., Quaid-i-Azam University, PK

Substituted phenols are important industrial products and ubiquitous in aquatic environment. Their environmental toxicity and resistance against biodegradability make them a persistent pollutant and major environmental hazard. The wide spread use of these contaminants have [...]

Synthesis and Characterization of ZnO Nanorods using Molecular Beam Epitaxy

Asghar M., Ali A., Hasan M.-A., Yasin Akhtar Raja M., Islamia University of Bahawalpur, PK

ZnO nanorods stand out as one of the most important candidates for next generation opto- and nano electronics. Synthesis of high quality and stable ZnO nanorods remains a challenge thus far. Similarly fabrication of thermally [...]

Synthesis and Characterizations of nano sized Barium hexa-ferrites using sol gel method

Iqbal M.A., Mir A., Punjab University, PK

Nanosized Barium Hexaferrites were synthesized by sol gel auto combustion method. Samples of different composition with varying molar ratio of metal nitrates and citric acid i.e. (MN_A= 0.5, 1, 1.5, 2, 3) were prepared. Pellets [...]

Method of enhancing polyaniline conductivity using different oxidizing agents as dopant

Iqbal M.A., Manzoor S., Punjab University, PK

The synthesis and characterization of Polyaniline pellets has been analyzed by using three different oxidizing agents like Ammonium per oxy disulphate (APS), Hydrogen per oxide and Potassium dichromate. Samples of different molar ratios of Aniline [...]
