This study aims to discuss the combined theoretical and experimental results of elastic properties tungsten trioxide films supported on Quartz (YX)/45°/10° resonator form surface acoustic wave (SAW) devices. The SAW systems with different thicknesses WO3 thin were imaged structurally characterized by X-ray diffraction, atomic force, transmission electron microscopy. deposited (100, 200, 300 nm ...

Abstract SCAPS simulation was utilized to complement previously published perovskite-on-Si tandem solar devices and explore herein viable all-perovskite 4-T mechanically stacked 2-T monolithic non-Pb structures. CsSn 0.5 Ge I 3 (1.5 eV) used as top cell wide bandgap absorber, while CsSnI (1.3 chosen bottom low absorber. The simulated with AM 1.5G 1 Sun spectrum, the filtered spectrum from cell....

In many countries of the world, rigid and flexible pavements are widely used. Some external factors such as stresses displacements play major role in design pavement layers coating, base sub-base. Although empirical formulas methods were used calculation layers, complexity today's transportation engineering demands effectiveness diminished. Nowadays complex problems can be easily simulated solv...

LaF3/SrF2 multilayer heterostructures with thicknesses of individual layers in the range 5-100 nm have been grown on MgO(100) substrates using molecular beam epitaxy. The longitudinal conductivity of the films has been measured using impedance spectroscopy in the frequency range 10-1-106 Hz and a temperature range 300-570 K. The ionic DC conductivities have been determined from Nyquist impedanc...

Introduction:  Pressure  sores  refer  to  lesions  that  are  produced  while  a  constant  pressure  causes  necrotic  tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation  of  pressure  sores.  Modeling  the  mechanical  behavior  of tissue  will  provide  a better understanding  of this  process as well as a more suitable selection ...

Aim. To investigate the effect of more than 25-year cigarette smoking on choroidal and retinal thickness, using spectral domain optical coherence tomography (SD-OCT). Methods. Thirty-one smokers and 25 age- and sex-matched nonsmokers, serving as control group, were submitted to slit-lamp biomicroscopy and dilated fundoscopy, SD-OCT, measurements of intraocular pressure (IOP), central corneal th...

PURPOSE The outer nuclear layer (ONL) contains photoreceptor nuclei, and its thickness is an important biomarker for retinal degenerations. Accurate ONL thickness measurements are obscured in standard optical coherence tomography (OCT) images because of Henle fiber layer (HFL). Improved differentiation of the ONL and HFL boundary is made possible by using directional OCT, a method that purposef...

PURPOSE To quantify and compare structure and function across the macula and peripapillary area in Stargardt disease (STGD1). METHODS Twenty-seven patients (27 eyes) and 12 age-similar controls (12 eyes) were studied. Patients were classified on the basis of full-field electroretinogram (ERG) results: Fundus autofluorescence (FAF) and spectral domain-optical coherence tomography (SD-OCT) hori...

Results of recent experimental measurements of the effect of passive boundary layer flow control method using both singleand multiple-element Large-Eddy Break-Up devices (LEBU) on aero-optical distortions in turbulent subsonic boundary layers at a range of subsonic speeds are presented. Measurements at different locations downstream of LEBU devices were performed using a Malley probe to collect...
