Atomistic modeling of the effect of codoping on the atomistic structure of interfaces in alpha-alumina

Paul Bowen, Michael Stuer, Sandra Caroline Galmarini, Abhishek Tewari

Sintering aids or dopants have often been used successfully to limit the grain growth of alumina during sintering. Recently codoping of alumina with transition elements has been reported to produce additional effects in comparison to single doping in enhan ...

Preparation of homogeneous titania coating on the surface of MWNT

László Forró, Duncan Thomas Lindsay Alexander, Jin Won Seo, Klara Hernadi

Preparation of homogeneous and stable inorganic coatings on the surface of multi-wall carbon nanotubes (CNTs) was studied. Precursor compounds such as titanium (IV) bromide and titanium (IV) chloride were used to cover the surface of CNTs under either solv ...

Exotic droplets formed in microfluidic chips with uniform wettability

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker, Cédric Razaname, Guillaume Louis

Microdroplets are widely used in industrial processes. In the absence of external forces, droplets generally assume a spherical shape. Here, we present two methods to form non-spherical droplets in microfluidic glass chips. A uniformly hydrophobized chip h ...

A model for the water retention behavior of deformable soils including capillary hysteresis

Lyesse Laloui, Mathieu Nuth

Experimental findings on the hysteresis of the soil water retention curve, relating the degree of saturation to the matric suction, have to be superimposed with the aspects due to the soil matrix deformation. In order to set a comprehensive model for the r ...

An Improved CFD Tool to Simulate Adiabatic and Diabatic Two-Phase Flows

Bogdan Alexandru Nichita

With increasing computer capabilities, numerical modeling of two-phase flows has developed significantly over the last few years. Although there are two main categories, namely 'one' fluid and 'two' fluid methods, the 'one' fluid methods are more commonly ...

Lateral Capillary Forces of Cylindrical Fluid Menisci: A Comprehensive Quasi-Static Study

Massimo Mastrangeli

Capillarity is pivotal to many important technologies, including capillary self-alignment and self-assembly for heterogeneous microsystem integration and packaging. Lateral capillary forces ensuing from perturbed fluid menisci were the object of substantia ...

Investigation of the size of plastic zones in nano indentation and nano scratching

Jean-François Molinari, William Curtin, Till Junge

Friction and the associated wear are important but still poorly understood phenomena with strong impacts on our every day lives. Several mechanisms, such as plasticity, lattice vibration, and third-body interactions contribute to the dissipation of energy ...

Size-fractionated characterization and quantification of nanoparticle release rates from a consumer spray product containing engineered nanoparticles

Christian Ludwig, Andrea Ulrich, Harald Hagendorfer

This study describes methods developed for reliable quantification of size- and element-specific release of engineered nanoparticles (ENP) from consumer spray products. A modified glove box setup was designed to allow controlled spray experiments in a part ...
