The hot deformation characteristics of AZ31 magnesium alloy rod extruded at temperatures of 300 °C, 350 °C and 450 °C have been studied in compression. The extruded material had a fiber texture with > < 0 1 10 parallel to the extrusion axis. When extruded at 450 °C, the texture was less intense and the > < 0 1 10 direction moved away from the extrusion axis. The processing maps for the material...

The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...

volatile compounds generated from two types of polymeric laminated films, irradiated by gamma radiation at 8, 10 and 15 kgy, were investigated. activated carbon was used as a dry food simulant to trace the migrating compounds by gas chromatography/mass spectroscopy (gc/ms). the resulting data showed that the polyethylene terephthalate (pet)/polyethylene terephthalate (pet)/linear low density po...

Outer membrane of Gram-negative bacteria is a permeability barrier to many antibacterial agents, including the glycopeptide antibiotics such as vancomycin hydrochloride and as a result these antibiotics are ineffective against Gram negative bacteria. Different strategies have been described to overcome such limitation, including application of nanoparticles, as was shown in our previous studies...

Samples of 99.9% pure, as-cast magnesium (Mg) were processed by Equal Channel Angular Extrusion (ECAE) using up to four passes the BC route, a temperature 250 °C, and three different extrusion rates 0.127, 0.381, 0.762 mm/s. The microstructures textures resulting samples characterized Electron Backscatter Diffraction (EBSD) as function pass rate. average grain size was reduced significantly app...

In the pharmaceutical industry, the conventional tablet manufacturing process, a batchbased process based on solid powder handling, presents challenges such as inhomogeneous blending between Active Pharmaceutical Ingredients (APIs) and excipients, low yield, and low production rate. These difficulties can be resolved by the realization of a continuous manufacturing process through co-processing...

Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed tracks. The biopolymer–ink interaction results in narrower printed tracks comp...

The main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. Pellet cores of budesonide were prepared by extrusion / spheronization technique. Pectin, in different ratios was combined with Eudragit RS30D, Eudragit NE30D or Surelease to produce film coating. The dissolution profiles of pectin coated pellets were investigated in pH of 1.2 (2 ...

We have detected a second-order nonlinear optical response from aggregates of the ampholytic megamolecular polysaccharide sacran extracted from cyanobacterial biomaterials by using optical second-harmonic-generation (SHG) microscopy. The SHG images of sacran cotton-like lump, fibers, and cast films showed SHG intensity microspots of several tens of micrometers in size. The dependence of the SHG...
