over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (tfc) membranes. in advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (tfn) membranes. however, in the last generation of tfns, an ultrathin selective film of nanoparticles is coated...

In a recent paper [Phys. Rev. Lett. 97, 070401 (2006)] the transition rate of magnetic spin-flip of a neutral two-level atom trapped in the vicinity of a thick superconducting body was studied. In the present paper we will extend these considerations to a situation with an atom at various distances from a dielectric film. Rates for the corresponding electric dipole-flip transition will also be ...

Article history: Received 26 June 2016 Accepted 6 July 2016 Available online xxxx Degradation mechanism of foldable thin film transistors (TFTs) is investigated experimentally by electrical, mechanical and electrical–mechanical hybrid stress experiments. Mechanical and electrical stress environment was set for foldable TFTs and the degradation effect according to the applied stress is investiga...

If a tangle, K ⊂ B, has no planar, meridional, essential surfaces in its exterior then thin position for K has no thin levels.

PRODUCT DESCRIPTION The AD688 is a high precision ±10 V tracking reference. Low tracking error, low initial error and low temperature drift give the AD688 reference absolute ±10 V accuracy performance previously unavailable in monolithic form. The AD688 uses a proprietary ion-implanted buried Zener diode, and laser-waferdrift-trimming of high stability thin-film resistors to provide outstanding...

A desired reflectance profile versus frequency (wavenumber) can be directly Fourier transformed into the index of refraction profile as a function of thickness which would produce the desired spectral reflectance profile. This tool has existed for some years now but does not seem to be in common use. This paper lays out some of the principles to aid in making the process more understandable, in...

The focus of this thesis is to analyze cost trends and government incentives in the California PV market during 2007-2008. The data show that pre-rebate system costs increased in California during this time period and that this was driven by a surge in worldwide module cost. Systems employing thin film technology did not exhibit a downward impact on cost, which contradicts historical and techno...
