Positronium formation in semicrystalline poly(ethylene terephthalate)
(Elsevier, 1994-01)
The probability of positronium (Ps) formation in semicrystalline poly(ethylene terephthalate) (PET), has been investigated by means of positron annihilation lifetime spectroscopy (p.a.l.s.). The p.a.l.s. data are correlated ...
Part-load optima in bottoming-cycles
(Elsevier, 1987-07)
It is assumed that optimal steam conditions for a Rankine bottoming-cycle are those that produce the greatest power output. It is then demonstrated that optimal steam conditions are a function of steam-generator pinch-temperature ...
Fatigue craze initiation in polycarbonate: study by small-angle X-ray scattering
(Elsevier, 1994-09)
The structural changes that occur during the incubation stage of tensile fatigue failure of glassy polycarbonate are investigated by means of small-angle X-ray scattering. The results are interpreted as the formation of ...
Industrial energy conservation and the steel industry of the United States
(Elsevier, 1987)
Energy use in industry, in particular manufacturing, is reviewed. Materials manufacture dominates. Natural gas and electricity are the main energy forms, with coal and oil now almost specialty fuels. Declining energy use ...
Energy demand and materials flows in the economy
(Elsevier, 1987)
Many forecasts show industrial energy use growing rapidly in industrial countries. These forecasts do not adequately take into account the diminishing importance of basic materials use in the economies of mature industrial ...
Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
