An updated three-zone heat transfer model for slug flow boiling in microchannels

This work proposes a novel physics-based model for the fluid mechanics and heat transfer associated with slug flow boiling in horizontal circular microchannels to update the widely used three-zone model of Thome et al. (2004). The heat transfer model has a ...

Investigation of polycrystalline ZnO film growth by quantitative TEM orientation mapping

Arthur Brian Aebersold

Polycrystalline chemical vapour deposited ZnO films are commonly used as transparent electrodes for photovoltaic devices. Over the past years much effort has been put into improving their properties. Even though these films are now well optimised for speci ...

Assemblies of gold nanoparticles at liquid-liquid interfaces : from liquid optics to electrocatalysis

Evgeny Smirnov

The interface between two immiscible liquids, i.e. oil and water, is an extremely attractive scaffold to self-assemble nanoparticles (NP) in arranged films. The liquid-liquid interfaces (LLIs) are defect-free and pristine by the nature, they are transparen ...

Elucidating the role of chlorine in perovskite solar cells

Ulf Anders Hagfeldt, Gang Wang, Jingshan Luo, Xiaoyu Zhang, Yi Ding, Di Zhang, Li Fan

It has been proposed that introducing the chlorine anion into a CH3NH3PbI3 perovskite material can substantially improve the materials properties as well as the solar cell performance. To elucidate the role of chlorine in perovskite solar cells (PSCs), her ...

Dynamics of isolated confined air bubbles in liquid flows through circular microchannels: an experimental and numerical study

John Richard Thome, Navid Borhani, Mirco Magnini, Sepideh Khodaparast

Experimental and numerical studies are performed to characterise the dynamics of isolated confined air bubbles in laminar fully developed liquid flows within channels of diameters d = 0.5 mm and d = 1 mm. Water and glycerol are used as the continuous liqui ...

Numerical simulation of 3D free surface flows, with multiple incompressible immiscible phases. Applications to impulse waves

Marco Picasso, Alexandre Caboussat

A numerical method for the solution to the density-dependent incompressible Navier-Stokes equations modeling the flow of N immiscible incompressible liquid phases with a free surface is proposed. It allows to model the flow of an arbitrary number of liquid ...

Formation of (113) texture in fcc nitride thin films and its influence on the film properties

Ayat Karimi, Alireza Karimi, Akshath Raghu Shetty

This work presents a study of XRD measurements on the development of the (113) preferential orientation with film thickness for Ti0.67Al0.33N films grown on Si(100) substrates by pulsed DC magnetron sputtering. The buildup of (113) texture was observed usi ...

Automatic Detection of Dust and Scratches in Silver Halide Film using Polarized Dark-Field Illumination

Sabine Süsstrunk, Dominic Rüfenacht

We present a method to automatically detect dust and scratches on photographic material, in particular silver halide film, where traditional methods for detecting and removing defects fail. The film is digitized using a novel setup involving crosspolarizat ...

Light trapping in solar cells at the extreme coupling limit

Christophe Ballif, Hans Peter Herzig, Franz-Josef Haug, Corsin Battaglia, Ali Naqavi

We calculate the maximal absorption enhancement obtainable by guided mode excitation in a weakly absorbing dielectric slab over wide wavelength ranges. The slab mimics thin film silicon solar cells in the low absorption regime. We consider simultaneously w ...
