- Description:
- In this work, the processing of the superconductor MgB<sub>2</sub> was studied to create a fundamental scientific background for the production of superconducting composite wires. The synthesis of MgB<sub>2</sub> from Mg and B powders was investigated in situ to determine reaction rates and kinetic parameters for the application of powder-in-tube technology...

- Graphene sheets (one-atom-thick, two-dimensional layers of sp2-bonded carbon) are predicted to have a range of unusual properties. Recent studies have shown that individual graphene sheets have extraordinary electrical properties, but an efficient method of graphite exfoliation remains a challenge. A number of approaches to exfoliation have been tried, such as...

- The first essay examines how the shift between single-tasking and multitasking influences productivity and workers' bargaining power, and its implications on the distribution of earnings between management and workers. Under single-tasking, a firm can obtain high productivity because workers' hold-up power can provide them with larger incentives to work. In...

Pulsed-laser local electrode atom probe tomography was used to determine the concentration and distribution of Mn in the Ge nanowires....

- Description:
- Silver nanoparticles exhibit distinctive optical properties. When exposed to electromagnetic radiation, a noble metal nanoparticle demonstrates the unique optical property of localized surface plasmon resonance (LSPR). LSPR is measured through an extinction spectrum, the sum of absorption and Rayleigh scattering, which results when the collective oscillation of electrons is resonant...

- When the Aß peptides aggregate into soluble oligomeric clusters, they form central nervous system neurotoxins known as amyloid-ß-derived diffusible ligands (ADDLs). The assembly of ADDLs is currently thought to be a pathogenic process in Alzheimer's disease (AD). Understanding the molecular structure and properties of ADDLs could prove useful in the...

- Numerous studies have been structured to investigate magnetoelectric multiferroic materials, which possess simultaneous ferroelectric and (anti)ferromagnetic ordering. Bismuth ferrite (BiFeO3), referred to as BFO, has drawn special attention because of its unique ability to maintain both electric and magnetic dipole moments at room temperature. BFO shows great potential to revolutionize...

- A self-assembled monolayer of an alkene or alkyne can be applied to a hydrogenpassivated silicon surface using UV hydrosilylation. This research shows that field-induced oxides can be used as a negative resist to selectively prevent bromostyrene attachment, providing a means of nanopatterning organic molecules on silicon. The negative resist effects...
