PVC pipes in gas distribution: still going strong! [PDF]
In the Netherlands (impact-modified) PVC is the preferred material for low-pressure (30 and 100 mbar) gas distribution systems. More than 50% of the total length (about 122,000 km) of this system is rigid PVC or impact-modified PVC.

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...

The brittle-ductile transition in γ-TiAl single crystals
Fracture tests in the temperature range 20–800°C were performed on single crystal γ-TiAl (Ti-54.7% Al) specimens. All tests were by four-point bending; the specimens were precracked by spark discharge so thatK1c could be determined. Two orientations of specimens were used, chosen so that the influence on the fracture behaviour of the ‘ordinary ...

Chemically Doped Conductive Polymers for Wearable Health Monitoring
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
