Why is graphite used as a dry lubricant in machinery ? AEach carbon atom undergoes sp3 hybridization in graphite BGraphite has layered structure and it cleaves easily between the layers and therefore it is very soft and slippery CGraphite is a non-conductor of electricity DGraphite has two sigm...
During this decade, graphene which is a thin layer of carbon material along at ease with synthesis and functionalization has become a hot topic of research owing to excellent mechanical strength, very good current density, high thermal conductivity, superior electrical conductivity, large surface area,...
Why is graphite a good conductor whereas diamond is not? (Both contain infinite lattices of covalently bound carbon atoms) What are atoms and why are they important? Explain why metals conduct electricity. Explain the origin of the ``chemical shift" seen for a p...

Why is polymer chemistry important? Why is H bonding so important to water's properties? Why do magnets have a magnetic field? Why is charcoal brittle? Why is graphite insoluble? Why is iodine a solid at room temperature? How does the type of wire affect resistance in a wire?
the CEOs of 19 major mining companies, including Coeur Mining, Hecla Mining, and First Majestic Silver, made the case for silver’s inclusion. Their argument centers on silver’s unmatched properties, including its status as the best electrical conductor, thermal conductor, and reflective material ...
graphiteelectrical resistivityKTB holeThe low-resistivity anomaly close to the KTB borehole coincides with both a self-potential and a static magnetic anomaly. If this coincidence is not accidental, it may yield information about the conditions required for the existence of low-resistivity anomalies ...
For intrinsic semiconductor, the know its conductivity=2 neμ , where his the number of electron per cubic meter, e is the charge of an electron, μ is the electron mobility. But if I want to calculate the conductivity of a conductor= neμ. Why not consider the hole in? Electron ...
Images of uniform and upright nanowires are fascinating, but often, they are quite puzzling, when the substrate is clearly not an epitaxial template. Here, we reveal the physics underlying one such hidden growth guidance mechanism through a specific exam
I’ve had bad sessions on the driving range followed by good rounds of golf too, it’s not always good (range) to bad golf. For me the driving range is for warming up, or for working on very specific swing elements. A lot of people hit balls without a real purpose on driving ...
