information is available about the data sets. There are also unsupervised methods, such as hierarchical clustering, which can be used to determine the components in a data set without any prior information about the data. The use of calibration methods in infrared spectroscopy[r]
The energy storage potential of silver oxide thin film electrodes, deposited via radio frequency reactive magnetron sputtering, was investigated in an ionic electrolyte 1-Ethyl-3-methylimidazolium bis imide for supercapacitor applications.

Silver nanoparticles (30-70 nm) have been impregnated on the activated graphite powder by an electroless plating method. The so prepared silver decorated graphite powders are characterized by field emission scanning electron microscopy, powder X-ray diffraction, energy dispersive X-ray and X-ray pho[r]

The elastic constants and various optical properties of MnIn2S4including the dielectric constant, absorption coefficient, electron energy loss function and reflectivity were calculated a[r]
Methods of physical chemistry, such as quantum chemistry and spectroscopy, have become routine tools in all subfields of chemistry, and developments in statistical theory have raised the[r]
We characterized their shape and morphology using transmission electron microscopy (TEM), and confirmed their crystalline structure with X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) in combination with energy-dispersive X-ray spectroscopy (EDX) elemental mapping.
This lecture is related to the “high-energy” “non-optical” electron spectroscopy covered in the X-ray lecture Methods: – Atomic absorption – Atomic emission e.g ICP-OES – Molecular U[r]

However, commonly, the exact line search is expensive. Especially, when an iterate is far from the solution of the problem, it is not effective to solve exactly a one-dimension subproblem. Also, in practice, for many optimiza- tion methods, for example, Newton method and quasi-Newton me[r]
