Resistance Responses in Pseudomonas aeruginosa PAO1 in Response to Surface Predation by Myxococcus xanthus DK1622
… the cellular level. Timelapse videos showed that ripple formation is inhibited at 48 hours. “Fold” deficient <em>P. aeruginosa</em> PAO1 strains clarified that <em>M. xanthus</em> is responsible for the appearance of the fold by showing complete blockage of <em>M. xanthus </em>motility after 48hr. …

Studies of ion beam nanopatterning on silicon and polymer thin film
Ion bombardment can lead to a spontaneous formation of a range of nanopatterns on surfaces, including nanodots, nanoscale ripples, and nanoscale pits or holes. Research in this thesis is mainly focused on the behavior of ripple patterns on silicon surfaces as a function of the ion incidence angle. …

Structural and thermal properties of graphene - boron nitride superlattice
… mechanisms: nanoscale misfit dislocations, and ripples via out–of–plane deformation. For flat superlattices, a critical superlattice pitch (thickness) exists beyond which the interface is decorated by strain–relieving misfit dislocations. For superlattices that can deform out–of–plane, …

Development of a Multiscale Atomistic Code to Investigate Self-Organized Pattern Formation Induced by Ion Irradiation
<p>Various self-organized patterns including ripples and quantum dots can be induced by ion beam sputtering (IBS). For the past decades, the understanding of such phenomenon has been mainly relied on the Bradley-Harper theory that attributes the formation of self-organized patterns to the interplay …

Nanoscale Investigation of Adhesion, Friction, and Wear in Chemically Heterogeneous Responsive Polymer Brushes
… mode for PS brushes (treated with toluene) was ripple formation. In case of P2VP brushes (treated with ethanol) and PAA brushes (treated with pH 10 water), wear occurred via removal of the polymeric material. Wear mechanism observed for the monobrushes was similar to that observed for the …

Atomistic disorder effects on structural, electronic and phononic properties in Si1-xGex
While single crystalline materials such as Si dominate a myriad of applications, alloy materials like Si1-xGex are becoming increasingly attractive because of their enhanced material properties. Their intriguing material properties originate from the distribution of constituent species that depends …
