The field of medical diagnostics will have tremendous potential gains in the near future due to Raman spectroscopy and microscopy. Applications include surface-enhanced Raman spectroscopy (SERS), signal enhancement targeted to specific analytes, coupling atomic force microscopy (AFM) systems and enabling tip-enhanced Raman spectroscopy (TERS) for nanoscale resolution. These technologies highlig...

The benign environment and long confinement times obtained with ion storage techniques have led to some unique experiments in the area of precision measurements and fundamental constants. This is perhaps epitomized by the single electron g factor measurements at the University of Washington in which a precision of 4 parts in 10” has been attained. Now, use of lasers to cool stored ions has allo...

Multiwall carbon nanotubes, prepared by chemical vapor deposition, have an average diameter of 60-100 nm as shown by High Resolution Transmittance Electron Microscope, HR-TEM. The Multiwall carbon nanotubes (MWCNTs) were further characterized using X-ray Diffraction and Raman Spectroscopy. Mercury uptake capacity of MWCNTs was studied using batch adsorption method at different concentration ran...

We explore the potential of direct spectroscopy of ultranarrow optical transitions of atoms localized in an optical cavity. In contrast to stabilization against a reference cavity, which is the approach currently used for the most highly stabilized lasers, stabilization against an atomic transition does not suffer from Brownian thermal noise. Spectroscopy of ultranarrow optical transitions in a...

This letter introduces a localized microwave technique for direct excitation of solid materials for the sake of their identification by atomic emission spectroscopy. The microwave energy is concentrated on the material surface by a microwave-drill type applicator. The evolved 1-mm hotspot is slightly evaporated and excited as plasma. An optical spectrometer measures the atomic emission spectrum...

The Virtual Atomic and Molecular Data Centre (VAMDC) is an EU-FP7 project devoted to build a common electronic infrastructure for the exchange and distribution of atomic and molecular data. Within VAMDC scientists from many different disciplines in atomic and molecular physics collaborate with users of their data and also with scientists and engineers from the information and communication tech...

The composition of the first atomic layer of Cu3Au(001) crystal (about half-and-half copper and gold atoms) changes only slowly even at temperatures much higher than that of the order–disorder transition (TC = 663 K). Theoretical and experimental works show a general trend of these changes but they differ in quantitative findings. In the present work we used directional elastic peak electron sp...

Aberration correction in the Scanning Transmission Electron Microcope (STEM) is pushing the achievable spatial resolution for imaging and spectroscopy into the sub-angstrom regime, providing a new level of insight into the structure/property relations of complex materials. The combination of atomic-resolution Z-contrast scanning transmission electron microscopy and electron energy loss spectros...
