Shooting resistance of non-metallic materials

Sustainable Non-Metallic Building Materials

Buildings are the largest energy consumers and greenhouse gases emitters, both in the developed and developing countries. In continental Europe, the energy use in buildings alone is responsible for up to 50% of carbon dioxide emission. Urgent changes are, therefore, required relating to energy saving, emissions control, production and application of materials, use of renewable resources, and to...

Shooting Nanoparticles Metallic Shine Size Matters

Understanding the structure of liquid/solid interfaces is important for applications such as catalysis and electrochemistry. Now, Voïtchovsky et al. report the probing of various liquid/solid interfaces, on an atomic and molecular scale, using small-amplitude modulation atomic force microscopy (AFM). The solid and the dynamically operated AFM cantilever are both immersed in the liquid during th...

The Nernst Lamp ELECTRICAL CONDUCTIVITY IN NON-METALLIC MATERIALS

The use of carbon and tungsten filaments mounted in vacuum as early incandescent lamps is well-known, but it is less often realised that an early competitor was Nernst’s ceramic lamp. This made use of the property that , although good insulators at room temperature, many oxides become partially conductive when strongly heated. This is due to the migration of ions rather than electrons, and was ...

NON - SPECIFIC RESISTANCE TO EXPERIMENTAL CHOLERA Materials

Thus, Bohnhoff et al. (1) made mice more susceptible to oral challenge with a streptomycin-resistant strain of Salmonella enteritidis by pretreatment with streptomycin. They concluded that this increase in susceptibility resulted from a disturbance of the normal intestinal microflora. Using a similar method, Freter (2-4) was able to induce an asymptomatie carrier state in guinea pigs and mice w...
