Analysis of plasma for carbon nanotube growth by plasma-enhanced chemical vapor deposition
Optical emission spectra of a CH4/H2/Ar gas mixture plasma were observed during carbon nanotube (CNT) growth in RF plasma-enhanced chemical vapor deposition. CNTs with diameters of ∼10-30 nm and length of ∼6 μm w...

Photochemical Control of Dark Conductivity - A New Approach to Devices Based on Molecular Crystals
Thermal analysis of Ag(DM)2, where DM = 2,5-dimethyl-N,N’- dicyanoquinonediimine, clarified that the salt had an insulating amorphous phase ( ≥ 155°C). Characterization of this and related solid states of Ag(DM)2

A novel gene is disrupted at a 14q13 breakpoint of t(2;14) in a patient with mirror-image polydactyly of hands and feet
Mirror-image polydactyly of hands and feet (MIP) is a very rare congenital anomaly characterized by mirror-image duplication of digits. To isolate the gene responsible for MIP, we performed translocation brea...

The absence of valence fluctuations in SmNi2Sn2
In an earlier work [1] an anomaly in the lattice volume had been observed in SmNi2Sn2 which indicated possible valence fluctuations of Sm ions. Using a well characterised sample of SmNi2Sn2, we do not find any ev...
