Nano-Micro Letters 2014年第4期6卷 293-300页

A procedure for joining polyol-synthesized silver nanowires in air using current-induced Joule heat welding is reported. Using a common probe station and photolithographically patterned gold electrodes, the welding process is completed using a common semiconductor analyzer. A unique two-step procedure eliminates the dielectric barrier at the point of contact without damaging the nanowires away from the junction. This procedure is designed for metal–metal contacts where a strong dielectric intermediate layer might exist, which can occur with metals prone to oxidation or corrosion in air, or as a result of the electrode deposition process. Ohmic connections are also established in cases where there is an initial gap between two nanowires.

In this study,the role of twin-twin interactions on the distributions of local defects(e.g.,dislocations)and stress fields in a magnesium alloy is investigated.A co-zone(1012)-(1012)tensile twin junction in a deformed Mg-3wt.%Y alloy is analyzed using transmission electron microscopy(TEM).The results show that the morphology of the impinging(1012)twin is asymmetric,and the non-interacting boundary of the recipient(1012)twin is *** analysis of TEM images reveals that type-II pyramidal[1213](1212)dislocations concentrate in the vicinity of the twin-twin junction *** samedislocations are also observed inside the interacting twin domains along with a few ***dislocations emanating from the impinging(1012)twin boundary have edge character and are extended with faults parallel to the basal *** contrast,thedislocations connected to the recipient(1012)twin are predominantly screw orientation and ***-viscoplastic fast Fourier transform based crystal plasticity calculations are performed to rationalize the observed twin morphology and local dislocation *** model calculations suggest that the local stress fields generated at the junction site where the two twins meet are responsible for the experimentally observed concentration of*** calculated stress fields are asymmetric with respect to the junction site,explaining the observed asymmetric morphology of the impinging ***,these findings show strong effects of twin-twin interactions on the distribution of dislocations as well as the evolution of the twinned microstructure and as such,can help advance understanding of twinning in Mg alloys and their effect on mechanical behavior.

The numerical approximation of the Spectral-Lagrangian scheme developed by the authors in [30] for a wide range of homogeneous non-linear Boltzmann type equations is extended to the space inhomogeneous case and several shock problems are benchmark. Recognizing that the Boltzmann equation is an important tool in the analysis of formation of shock and boundary layer structures, we present the computational algorithm in Section 3.3 and perform a numerical study case in shock tube geometries well modeled in for ID in x times 3D in v in Section 4. The classic Riemann problem is numerically analyzed for Knudsen numbers close to continuum. The shock tube problem of Aoki et al [2], where the wall temperature is suddenly increased or decreased, is also studied. We consider the problem of heat transfer between two parallel plates with diffusive boundary conditions for a range of Knudsen numbers from close to continuum to a highly rarefied state. Finally, the classical infinite shock tube problem that generates a non-moving shock wave is studied. The point worth noting in this example is that the flow in the final case turns from a supersonic flow to a subsonic flow across the shock.

A comprehensive review of what is known not only about the cause and treatment of atypical parksonian disorders, but also the issues that clinicians, researchers, patients, and caregivers face in dealing with them. The authors cover the basic science (history, epidemiology, genetics, pathology, nosology, computer modeling, and animal models), detailed clinical and laboratory assessments, and available diagnostic tools, including neuropsychiatric, neurologic, neuropsychologic, speech, electrophysiologic, and imaging evaluations. Current and future therapeutic approaches are also detailed, along with extensive discussions about future research directions. An accompanying DVD contains video segments that demonstrate how to examine patients with these disorders, how to differentiate them, and how to systematically use specific tests to better characterize them
