Nanoboron Nitrides

Amir Pakdel、Yoshio Bando、Dmitri Golberg2015-01-26OpenAlex

BN is a chemical compound, consisting of equal numbers of boron (B) and nitrogen (N) atoms, which is not found in nature and is therefore produced synthetically. BN is isostructural to carbon (C) and exists in various crystalline forms. e hexagonal form (h-BN) is analogous to graphite with a layered structure. is can…

Microtweezers for studying vibrating carbon nanotubes

Arthur Barnard2015-01-26eCommons (Cornell University)

Vibrational modes in suspended carbon nanotubes (CNTs) are incredibly soft, which makes them sensitive to small forces and prime candidates as force sensors. This same property, combined with the stiffness of the CNT to stretching, makes them an unusual mechanical system characterized both by large thermally-activated…

Determining The Energy Profile And Polymorphs Of 6,13-Tips Pentacene In Vacuo And In Solvent

Kristina M. Lenn2015-01-26eCommons (Cornell University)

Organic semiconducting materials are gaining popularity as solar cell materials, in large part because of their ability to be processed onto flexible substrates and to be manufactured more cheaply. However, organic materials are not nearly as efficient as silicon in regards to charge transport. To circumvent this, a p…

Actin nucleators in microvillar assembly: Cordon Bleu as a novel microvillar protein

Jessica Wayt2015-01-26eCommons (Cornell University)

Epithelial cells polarize through reorganization of the actin cytoskeleton which results in distinct apical and basolateral domains. At the apical domain are structures called microvilli, which are plasma membrane protrusions tethered to a bundled actin filament core. It has been shown that ERM proteins, specifically…

A Computational Investigation Of Ductile Failure In Al5083-H116 And The Shear Strengths Of Pure Aluminum Grain Boundaries

Geoffrey Bomarito2015-01-26eCommons (Cornell University)

Computational models, besides their relatively low cost, offer the benefit of complete control over all testing variables (e.g., atmospheric conditions, loading rates, applied stress states), which can be difficult to control in experiments. This control can be used to identify key controlling parameters and improve o…
