The increasing demand for rare earth (RE) elements in advanced materials for permanent magnets, rechargeable batteries, catalysts and lamp phosphors necessitates environmentally friendly approaches for their recovery and separation. Here, we propose a mineralization concept for direct extraction of RE ions with Lamp (lanthanide ion mineralization peptide). In aqueous solution containing various...

A concept is presented for synthesizing metal nanowires directly from the vapor phase using chemical vapor transport to temperatures higher than the corresponding metal oxide decomposition temperature. Specifically, this concept is demonstrated with the synthesis of tungsten metal nanowires with sizes ranging from 70 to 40 nm by increasing the condensation temperature. The simultaneous condensa...

We report a robust method of stabilizing laser to the frequency an atomic transition using hollow cathode lamp. In contrast standard dichroic vapor lock (DAVLL) method, which uses dichroism induced by longitudinal magnetic field, we employ birefringence transversal field. applied this $(5s^2)\ {}^{1}S_{0} - (5s5p)\ {}^{1}P_{1}$ (461 nm) Sr. Although is made ferromagnetic material, successfully ...

In this mid-term we will study the dynamics of an atomic clock, mF which is one of the applications of David Wineland’s research (No­ bel prize in physics 2012). We consider a simplified (and sometime inaccurate) model of a vapor-cell atomic clock . Light from a lamp passes through a vapor of rubidium atoms housed in a glass cell and is detected by a photodiode. The light intensity transmitted ...

In this study, a gold amalgam method called the "Double amalgam method" was compared with the ISO 17733 method for mercury vapor analysis method. In terms of sensitivity and ease of operation, the amalgamation method is superior to the oxidation method. Two parallel samplings were carried out in this research at a button battery factory, where the mercury vapor level in the air was about 0.001 ...

We present grazing-incidence Fourier transform infrared and AFM data of Au, Al, and Ti vapor-deposited onto self-assembled monolayers (SAMs) of conjugated mono- and dithiols. SAMs of 4,4'''-dimercapto-p-quaterphenyl, 4,4"-dimercapto-p-terphenyl, and 4,4'-dimercapto-p-biphenyl have reactive thiols at the SAM/vacuum interface that interact with vapor-deposited Au or Al atoms, preventing metal pen...

The solution of a boundary–value problem formulated for a modified Kretschmann configuration shows that the phase speed of a surface–plasmon wave guided by the planar interface of a sufficiently thin metal film and a chiral sculptured thin film (STF) depends on the vapor incidence angle used while fabricating the chiral STF by physical vapor depoistion. Therefore, it may be possible to engineer...

We measure and analyze the isotope shifts multiplet of transitions between metastable a$^5$F excited y$^5$G$^\circ$ terms neutral titanium by probing a vapor in hollow cathode lamp using saturated absorption spectroscopy. resolve five $J\to J+1$ four J$ within for each three $I=0$ stable isotopes ($^{46}$Ti, $^{48}$Ti, $^{50}$Ti). The on these allow us to determine isotope-dependent variation f...
