Experiments are performed to provide an insight into the heat transfer aspects of a wavy liquid film. Local film thickness and liquid temperature are measured simultaneously using a thermal conductance thickness probe and fast response thermocouples as the wavy film falls over an electrically heated wall. Liquid temperature at a fixed distance from the wall generally increases in the thin subst...

Titanium dioxide (TiO2) ultrathin films with different thicknesses below 20 nm were grown by atomic layer deposition (ALD) on silicon substrates at 300 °C. Spectroscopic ellipsometry (SE) measurements were operated to investigate the effect of thickness on the optical properties of ultrathin films in the spectra range from 200 to 1000 nm with Forouhi-Bloomer (F-B) dispersion relation. It has be...

A comprehensive experimental investigation has been carried out into the role of film thickness variation and silver material formulation on printing capability in the screen printing process. A full factorial experiment was carried out where two formulations of silver materials were printed through a range of screens to a polyester substrate under a set of standard conditions. The materials re...

The continuum theory of micromagnetism is used to study ultrathin films with magnetic anisotropy varying laterally on the nanometer scale. A series of infinitely long stripes with alternating inand out-of-plane uniaxial anisotropy is considered as a model for patterned ferromagnetic films. The analytical solution based on an effective anisotropy description of the dipolar energy is given as a f...

Structural characteristics of phase transformations in epitaxial ferroelectric films are analyzed via a Landau–Devonshire thermodynamic formalism. It is shown that the phase transformation temperature, the lattice parameters, and the order of the phase transformation are a strong function of the misfit strain and are considerably different compared to unconstrained, unstressed single crystals o...

CdSe nanostructures were synthesized by using green chemical route as starch was used as capping agent. XRD, HR-TEM, SEAD, UV and PL studies were made for structural and optical properties of the prepared sample. Film morphology and the thickness measurement of n-CdSe were carried out with AFM analysis. I-V characteristics curve of this junction confirmed the formation of Schottky contact betwe...

Nanoscale, vanadia-based, quasi-liquid films of self-selecting (equilibrium) thickness were observed on TiO2 surfaces in six ternary oxide systems (Ti–V–X–O; X = P, Na, K, Nb, Mo or W). It is demonstrated that the film appearance and thickness could be tailored via co-doping or changing the equilibration temperature. Furthermore, the observed discontinuous changes in film thickness, hysteresis ...

In this paper we consider a type-I superconducting film modeled by the Ginzburg-Landau model, confined between two parallel planes a distance L apart from one another. Our approach is based on the Gaussian effective potential in the transverse unitarity gauge, which allows to treat gauge contributions in a compact form. Using techniques from dimensional and ζ-function regularizations, modified ...

The influence of the film thickness and the substrate’s refractive index on the surface mode 7 at the superstrate is an important study step that may help clearing some of the misunderstandings 8 surrounding their propagation mechanism. A single sub-wavelength slit perforating a thin metallic 9 film is among the simplest nanostructure capable of launching Surface Plasmon Polaritons on its 10 su...

To ensure bearing reliability, it is traditional for compressor manufacturers to specify a minimum oil sump temperature difference above the saturated discharge temperature in a high-side compressor and suction temperature in a low-side compressor. This minimum oil sump temperature specification is, in essence, a surrogate measure of the minimum viscosity the compressor manufacturer reqtrires t...
