Diamond formation by reduction of carbon dioxide at low temperatures.
This Communication reports a low-temperature diamond synthesis technique, in which diamonds (10-250 mum) can form at a temperature as low as 440 degrees C by reduction of dense CO2 with metallic Na. The X-ray diffraction pattern of a powder sample shows three reflection peaks, indexed with 111, 220, and 311, corresponding unambiguously to cubic diamond. The Raman spectrum of the product exhibit...
متن کاملProton Transfers in Hydrogen Bonded Organic Crystals at Low Temperatures
The tunneling dynamics of protons involved in hydrogen bonds between carboxylic acid dimers is determined using picosecond transient grating techniques.
متن کاملLarge-N treatment of the Abrikosov transition at low temperatures
We investigate the influence of order-parameter fluctuations on the transition between normal and mixed superconducting states at low temperatures. We show that in the case of clean quasi-two-dimensional superconductors the transition can be described by the functional of the Ginzburg-Landau type. We consider the large-N generalization of this functional and using the lowest Landau-level approx...
متن کاملLarge-area graphene single crystals grown by low-pressure chemical vapor deposition of methane on copper.
Graphene single crystals with dimensions of up to 0.5 mm on a side were grown by low-pressure chemical vapor deposition in copper-foil enclosures using methane as a precursor. Low-energy electron microscopy analysis showed that the large graphene domains had a single crystallographic orientation, with an occasional domain having two orientations. Raman spectroscopy revealed the graphene single ...
متن کاملSample environment at low temperatures
2014 A review of low temperature techniques as applied to neutron scattering studies is presented. Methods of temperature measurements especially carbon thermometry are discussed. Problems of heat transfer are treated in detail for different kind of samples and some solutions are proposed. Revue Phys. Appl. 19 (1984) 677-683 SEPTEMBRE 1984, The number of neutron scattering studies at temperatur...
