The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper...

The resistance to destruction of spores of Bacillus subtilis var. niger hermetically sealed in various polymeric films and exposed to ethylene oxide with and without relative humidity was determined. The effect of desiccation was also determined. The order of increased resistance to sterilization with regard to type of polymeric film was found to be: polyethylene equal to polyvinyl chloride, le...

tissue engineering based on the adipose derived stem cells  promote a strong strategy to propagation of bone, cartilage and fat tissues in the three-dimensional scaffolds, fabricated by combining biological materials with suitable and appropriate growth factors.  in this study, a peo scaffold was used to show that mesenchymal stem cells can attach well; the aim of this study was the investigati...

The activation energy of thin films polymers made pure polyethylene oxide (PEO) andPEOdoped with 0.1 % by weight iodine were investigated. observed physical constants the cast films, such as determined. prepared casting method using electricity. This study investigated variation wt. a frequency in range 200-800 kHz and temperature 30-55°C. results proved that there is significant change values ...

The formation of water-in-water emulsions from the aqueous two phase system containing polyethylene oxide and pullulan, stabilised by montmorillonite platelets, was investigated. A novel approach of preparing the emulsions at non-equilibrium polymer concentrations was successfully utilised to control viscosity during mixing and allow the use of low energy emulsification methods. Polyethylene ox...

M41S: A family of mesoporous materials including MCM41, MCM-48, and MCM-50 MSU-1,2,3,4: Michigan State University no. 1, 2, 3, 4, a series of wormhole mesoporous materials prepared in the presence of nonionic surfactants Pluronic: polyethylene oxide–polypropylene oxide triblock surfactant, (EO)m(PO)n(EO)m, for example, P123 = (EO)20 (PO)70(EO)20 SBA-x: Santa Barbara no. x, a series of mesoporou...

An osmotic, oral, controlled-release capsule is described. This capsule provides drug delivery at fixed delivery rates (T(80%)=6 or 14h) independent of drug properties (e.g., solubility) or drug loading, thereby allowing rapid development of investigational or commercial drugs, especially for proof-of-concept type clinical studies. The capsule body and cap are prepared with cellulose acetate an...

nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...
