Through changing the argon pressure, CaB6 films with different crystallographic orientation and morphology on glass substrates were prepared by direct current (DC) magnetron sputtering method. The film textures, crystallite sizes, composition and morphology were investigated by a spectrum of characterizing techniques in terms of X-ray diffraction (XRD), field emission scanning electron microsco...

OBJECTIVE As the contamination of implant surface seriously affects the early osseointegration of implants and reduces the survival rate of implants, it has attracted wide attention of researchers. The most oral titanium implants used in current clinical applications are stored in sealed packages. During the process of packaging, storage and usage, the implants inevitably contact air, which res...

We report an optical dipole trap for calcium. The trap is created by focusing a 488-nm argon-ion laser beam into a calcium magneto-optical trap. The argon-ion laser photoionizes atoms in the trap because of a nearresonance with the 4s4f F3 level. By measuring the dipole-trap decay rate as a function of argon-ion laser intensity, we determine the F3 photoionization cross section at our wavelengt...

Intraparticle mass transfer processes of Phenol Blue (PB) in single octadecylsilyl (ODS)-silica gel microparticles in acetonitrile-water were analyzed by microcapillary manipulation and microabsorption methods. An absorption maximum of PB, the sorption isotherm parameters, and the sorption rate in the microparticle system were highly dependent on the percentage of acetonitrile in solution. The ...

Understanding argon release mechanisms in K-bearing minerals is essential in interpreting the ArrAr data and their application to geological studies. The release mechanisms of argon in vacuo have been examined in a series of ArrAr Ž . Ž a. isothermal heating experiments on two biotite specimens with Fer FeqMg Fe s0.50 and 0.87 respectively. The crystal structure of the biotite was also monitore...

The ICARUS and future liquid argon neutrino experiments generate demand for evaluating the spectral function of argon. In this paper we use oxygen nucleus as a testing ground for our phenomenological approach to the spectral function and probe the influence of momentum distribution and treatment of the mean field spectral function on the differential cross sections. The obtained model reproduce...
