Carbon nanoparticles (CNP) were synthesized in arc plasma discharge using a simple, low-cost and toxic-free precursor gas. The structural and electrical characteristics were examined. The diameter and the height of the grown CNP was 28.5 μm and  316.7 μm , respectively. SEM image showed existence of a high density and uniform nanostructures within the cylindrical bulk CNP tube. The average diameter of the nanoparticles is 600 nm. The electrical characteristics revealed  low resistance with R = 7.23 mΩ with Cu electrodes.  In addition, the device exhibited a   high conductivity of 6.8 x 105 Scm-1. These results indicate the potential of CNP material for power device applications.

Using scanning electron microscopy, X-ray photoelectron spectroscopy, and Raman scattering we studied the charge state of matrix and doping element atoms on the surface, morphology, and defects in the structure of graphene-like materials synthesized by plasma-arc discharge in liquid nitrogen.

Abstract Homogeneous control specimens for estrogen receptor (ER) and progesterone receptor (PR) assays were prepared from freshly collected human uterus. After removal of the connective tissue, the specimen was washed with isotonic saline, cut into small pieces, quickly frozen in liquid nitrogen, and stored at -70 degrees C until analyzed. Cytosol prepared from this specimen was lyophilized and stored at -70 degrees C. A single step of reconstitution, with glycerol (100 mL/L) in water, is sufficient to prepare a control. Two specimens prepared this way were found to be reasonably stable for 20 months (first specimen, mean +/- SD: ER = 22.1 +/- 2.9 fmol/mg, PR = 136.5 +/- 26.9 fmol/mg; second specimen: ER = 107.2 +/- 11.7 fmol/mg, PR = 922 +/- 71.6 fmol/mg). Another specimen, prepared similarly but not frozen in liquid nitrogen soon after collection, was less stable; its ER and PR concentrations deteriorated faster.
