New/Surface-Modified Biocompatible Polymer for ICD Lead Insulation

The average lifetime of an implanted pacemaker or defibrillator cable (lead) is approximately 10 years. One of the main lead failure mechanisms is deterioration of the insulation, which can be caused by chemical, biological, and mechanical processes. Each ...

Evaluation of residual strains in epoxy with different nano/micro-fillers using embedded fiber Bragg grating sensor

John Botsis, Marco Lai, Klaus Friedrich

The Influence of SiO2 nanoparticles and rubber micro-fillers on the mechanical and thermal responses of an epoxy based composite is investigated using classical quantitative thermo-mechanical testing (tensile tests DMTA TMA) microstructural analysis (Micro ...

Simplified concrete resistivity and rapid chloride permeability test method

A simplified method of measuring concrete resistivity, as an index of permeability, has been developed that is similar to ASTM C1202 or the rapid chloride permeability test (RCPT). It is significantly faster and easier to perform, however In this test, cyl ...

Theoretical Analysis of Fluid Inclusions for In Situ Soil Stress and Deformation Measurements

Dani Or

In situ determination of stress, strength, and deformation of soils for direct assessment of trafficability and susceptibility to compaction has been a long-standing problem in soil mechanics and agricultural engineering. Despite considerable progress in d ...

Assessment of the rheological properties of asphalt rubber binder and its residual phases

André-Gilles Dumont, Mehdi Ould Henia

The asphalt rubber blends design is an empirical procedure and is quite sensitive to the variability of the components properties. A better understanding of the physical phenomenon involved during the curing process is a prerequisite step to propose a rati ...

Modélisation et prédiction du comportement rhéologique des mélanges bitume caoutchouc

Mehdi Ould Henia

Asphalt rubber is a modified binder widely used in pavement construction. Composition design methods of asphalt rubber blends are exclusively empiric and rely on the selection of the optimal combination of parameters after a long experimental program. The ...

Ozone transfer and design concepts for NOM decolourization in tubular membrane contactor

Urs von Gunten

Ozonation membrane contact was carried out with a tubular membrane module to study the effects of the flow rates and the temperatures of the liquid phase on ozone transfer and on the enhancement of mass fluxes. Changes in liquid temperature gave both posit ...

Kinetics of collagen denaturation in tendon

Collagen is constituted of three polypeptides forming a triple helix maintained by numerous weak chemical interactions, such as hydrogen bonds. In connective tissue it further packs into very long cylinders of few nanometers of diameter, called fibrils. On ...

Primary or secondary batteries with electrodes comprising nanometer size particles

Michael Graetzel

In a high capacity primary or secondary cell, the active material of at least one of the electrodes is selected from transition metal oxides or their (partially) lithiated forms, such as TiO2, Nb2O5, HfO2, MnO2, LiyNiO2, LiyCo2, Ldy(NiCo)O2, or LiyMn2O4, i ...
