Composite material production of nonmetallic printed circuit board waste with recycled high density polyethylene [PDF]

, 2015
This research is intended to develop a new potential reuse of recovered nonmetallic materials of printed circuit boards (PCBs) and plastic waste. Recycling of these wastes are being attempted in order to reduce its harmful effects on the environment.

Nonmetallic behaviour in thin metal wires

, 1983
General expressions for the temperature coefficient of resistivity (TCR) of thin metal wires have been derived by incorporating the thermal expansion of the wire diameter and the wire-to-substrate expansion mismatch.

Electronic communications between active sites on individual metallic nanoparticles in catalysis

Nature Communications
Catalytic activity of metal particles is reported to originate from the appearance of nonmetallic states, but conductive metallic particles, as an electron reservoir, should render electron delivery between reactants more favorably so as to have higher ...

Influence of nonmetallic inclusions on microbreaks formation in wheel steel and railway wheels [PDF]

Transport Problems, 2008
It is well known that formation of defects of many types during railway wheels service somehow or other is connected to nonmetallic inclusions in wheel steel. Microbreakes connected with nonmetallic inclusions have different origin.
