Cross linking of high density polyethylene (HDPE) was first performed via high energy10 Mev electron beam (EB) irradiation. HDPE was also cross linked withDicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effectof nature of cross linking, correlation of electrical p...

The purpose of this study was to compare the effectiveness of both high volt galvanic current (HVG) and isometric exercise to strengthen the quadriceps femoris muscles in 17 healthy subjects. The subjects were divided into three groups. The Control Group (n = 6) received no exercise or stimulation. The Isometric Exercise Group (n = 5) performed 15 sessions of maximum isometric contractions, and...

Electrical forces are the background of all the interactions occurring in biochemical systems. From here and by using a combination of ab-initio and ad-hoc models, we introduce the first description of electric field profiles with intrabond resolution to support a characterization of single bond forces attending to its electrical origin. This fundamental issue has eluded a physical description ...

Three-dimensional (3D) graphene aerogels (GA) show promise for applications in supercapacitors, electrode materials, gas sensors, and oil absorption due to their high porosity, mechanical strength, and electrical conductivity. However, the control, actuation, and response properties of graphene aerogels have not been well studied. In this paper, we synthesized 3D graphene aerogels decorated wit...

Human red blood cell ghosts were prepared by dielectric breakdown of the cell membrane and subsequent electrical haemolysis in isotonic and isoionic solutions. Almost complete removal of haemoglobin (to about 0.1%) could be achieved by subjecting the erythrocytes suspended in isotonic solution to three consecutive electric field pulses of 16 kV/cm in the presence of 10 mM EDTA, followed by dilu...

Extended laser scanning confocal microscopy has recently been used to reconstruct the discontinuous laminar organisation of cardiomyocytes in a block of rat left ventricle. The confocal data allowed delineation of intercellular clefts or cleavage planes which coursed through the tissue block. This study describes a finite element model of electrical propagation which permitted the accurate inco...

Selective Laser Sintering (SLS) provides a way to fabricate graphite composite bipolar plates, which significantly reduces time and cost at the research and development stage of bipolar plates, as compared with the conventional fabrication methods of compression molding and injection molding. Different graphite materials (natural graphite, synthetic graphite, carbon black, and carbon fiber) wer...
