The mass density of nanowires is determined using in situ resonance frequency experiments combined with quasi-static nanotensile tests. Our results reveal an average mass density of 7.36 g/cm3, which is below the theoretical density of bulk cobalt. The res ...
The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...
A new cobalt(II) phosphate compd. has been synthesized using high-temp. flux methods in the CsCl/NaCl media at 650°C. The title compd., Na3CsCo7(PO4)6, forms vibrant purple plate crystals. It crystallizes in a monoclinic space group C2/c (no. 15) with the ...
Energy deposition rates in various materials irradiated in a large 60Co facility have been measured using both CaF2 and LiF TLDs. Since the relationship between energy deposited in the TLD and that deposited in the surrounding medium (1/f factor) was diffe ...
Tobacco Mosaic Virus (TMV) is composed of 2130 identical coat protein subunits following the right-handed helix of an accompanying RNA strand to produce a 300 nm hollow cylinder with an outer diameter of 18 nm and a 4 nm wide central channel. In this work, ...
The spatial evolution of compositions and sub-structures inside focused-electron-beam-deposited tips from dicobalt-octacarbonyl Co2(CO)8 precursor at 25 keV and varying beam current (20 pA - 3 A) is extensively studied for the first time by means of energy ...
The aim of this thesis was to synthesise and control a nanostructured composite of copper/cobalt. Both the copper and cobalt oxalate exhibit a nanostructure. Attempts to produce nanocomposite particles in the size range of 10-70 nm were made via an oxalate ...
γ-γ coincidence methods have been applied to obtain absolute flank and crater wear volumes from irradiated high speed steel (HSS) tools using 60Co as the radiotracer. Consistent absolute results can be obtained irrespective of the exact counting geometry o ...
