Surface Interactions of Diborane
… gas often employed in high-purity industrial surface processes such as chemical vapor deposition or epitaxial layer growth. The use of diborane at industrial scales is complicated by the formation of higher-order borane contaminants in pure diborane gas via a complex series of gas-phase …

Understanding shoe-surface interactions in football
… to identify how the shoe interacts with the surface during realistic football movements and then to use observations from data collected to recommend appropriate test parameters. A high-speed camera system was developed to capture the motion of the shoe in both a laboratory and natural turf …

Cell surface interactions of Coxsackie A9 virus
… in CAV9 research b) the significance of possible interactions between CAV9 and HSPG in infection. Several CAV9 variants were tested in a panel of 8 different cell lines. Infection in each cell line was observed to follow either an RGD- dependant or RGD- independent pathway, although the results …

PATTERNED BIOFILM FORMATION TO INVESTIGATE BACTERIA-SURFACE INTERACTIONS
<p>Bacterial adhesion to surfaces and subsequent formation of microcolonies play important roles in biofilm formation, which is a major cause of chronic infections and persistent biofouling. Despite the significance, mechanistic understanding of biofilm formation is still hindered by the structural …

Rough Surface Interactions of Micro/nano-Scale Contact Systems
… modulus values. Second, an improved rough surface contact model suitable for miniature systems has been developed accounting for both asperity and substrate deformation during contact. Compared to a representative asperity-based contact model, it was found that the proposed model is closer …

Scale-bridging molecular dynamics simulations of plasma-surface interactions
… manufacturing and biomedical industries. Plasma-surface interactions can be divided into two categories: controlled and erosive. Controlled plasma interactions are used to pattern the surfaces of materials to achieve desirable electronic and mechanical properties in an ionizing chamber. Examples …

Effect of Nanoscale Surface Structures on Microbe-Surface Interactions
… grow as biofilms on living and non-living surfaces. The development of biofilms on non-living surfaces is significantly affected by the surface micro/nano topography. The main goal of this dissertation is to study the interaction between microorganisms and nanopatterned surfaces. In order …

PLASMA-SURFACE INTERACTIONS DURING REACTIVE PLASMA PROCESSING OF HYDROCARBON FILMS
Reactive plasma interactions with hydrocarbon-based surfaces play a critical role in future biological-plasma applications and for microelectronic device manufacture. As device dimensions get smaller and we require fine control of surfaces during plasma processing we will need to develop more …

Orbital Level Understanding of Adsorbate-Surface Interactions in Metal Nanocatalysis
… using geometry-based reactivity descriptors of surface atoms and kinetic analysis of reaction pathways at various types of active sites. We show that orbitalwise coordination numbers 𝐶𝑁<sup>α</sup> (α = 𝑠 or 𝑑) can be used to predict chemical reactivity of a metal site (e.g., adsorption energies …

Investigating bacterial adhesion proteins as tools for controlling bacteria-surface interactions
Adhesins are cell-surface proteins that initiate target binding and surface colonization by bacteria on the path to infection and biofilm formation. A deeper understanding of the interactions between adhesins and their ligands may lead to the development of strategies for controlling infection and …

[57]Fe Mossbauer studies of surface interactions in a PVD process.
… Spectroscopy (CEMS) has been used to investigate surface interactions in a commercial Arc Bond Sputtering (ABS) coating system. A novel application of the Liljequist theory of CEMS has been used to determine ion etch rates for deposited natural iron on stainless steel substrates, for various Ti …

Modeling of complex surface interactions in low and high pressure plasmas
… for twisting is charge accumu-lation on feature surfaces during ion bombardment. An asymmetric local electric field (E-field) changes ion trajectories incident into the feature to one direction opposite the E-field. This causes twisting. Bowing at the top of the feature near the …

An experimental and numerical study of surface interactions in turbulent swirling jets
… or an array of fluid jets which impinge onto a surface. Traditionally, non-swirling impinging jets have been used, but interest surrounds possible advantages from imposing swirl into these jets to further promote heat and mass transfer at the surface. The challenge of resolving this question is …
