  1. We report measurements consistent with the valley Kondo effect in Si/SiGe quantum dots, evidenced by peaks in the conductance versus source-drain voltage that show strong temperature dependence. The Kondo peaks show unusual behavior in a magnetic…

  3. We report the growth of in-plane GaN wires on silicon by metalorganic chemical vapor deposition. Triangular-shaped GaN microwires with semi-polar sidewalls are observed to grow on top of a GaN/Si template patterned with nano-porous SiO2. With a…
  4. Next Generation Nuclear Plant (NGNP) designs for very-high-temperature reactors (VHTR) employ intermediate heat exchanger (IHX) for which the material demands are extreme. Currently, Alloy 617 and Alloy 800H are considered to be among the candidate…
  5. Nano-precipitates with tripled periodicity along the c-axis are observed in a Ca-rich dolomite sample from Proterozoic carbonate rocks with ``molar tooth{''} structure. This observation is consistent with previous description of d reflections.…
  6. The stability of Y-Ti-O nanoclusters, dislocation structure, and grain boundary segregation in 9Cr-ODS steels has been investigated following proton irradiation at 400 degrees C with damage levels up to 3.7 dpa. A slight coarsening and a decrease in…
  7. Photonic-crystal cavities compatible with the highly subwavelength thicknesses and flexibility requirements of mechanically-stressed Ge nanomembranes are developed and used to demonstrate a strong (20×) strain-induced light-emission efficiency…
  8. Ultrastable glasses and nanoglasses are two emerging materials with novel properties that have been investigated separately. In order to explore the combined effect of ultrastable character and a nanoglass with a nanoglobular microstructure on the…
  9. The qubit is the fundamental building block of a quantum computer. We fabricate a qubit in a silicon double-quantum dot with an integrated micromagnet in which the qubit basis states are the singlet state and the spin-zero triplet state of two…
  10. Three electrochemical methods - cyclic voltammetry (CV), chronopotentiometry (CP), and anodic stripping voltammetry (ASV) - were applied to solutions of up to 10 wt% UCl3 in the molten LiCl-KCl eutectic salt at 500 degrees C to determine…
  11. We report the growth of in-plane GaN wires on silicon by metalorganic chemical vapor deposition. Triangular-shaped GaN microwires with semi-polar sidewalls are observed to grow on top of a GaN/Si template patterned with nano-porous SiO 2. With a…
  12. The mechanical effect of a partial thickness tear or laceration of a tendon is analytically modeled under various assumptions and results are compared with previous experimental data from porcine flexor tendons. Among several fibril-level models…
  13. Surface modification of perovskites is a new approach to develop highly active and stable cathodes for solid oxide fuel cells. Here, we report that La0.8Sr0.2MnO3-delta (LSM82) surface decoration led to markedly enhanced activity and stability for…
  14. Ultrastable glasses and nanoglasses are two emerging materials with novel properties that have been investigated separately. In order to explore the combined effect of ultrastable character and a nanoglass with a nanoglobular microstructure on the…
