A new anion receptor 1, which utilizes only C-H hydrogen bonding have been designed and synthesized. This receptor utilizes both aromatic C-H (two perimidine C2-H, anthracene 9-H) and aliphatic C-H (two perimidine 1-methyl C-H, two benzylic C-H) as hydrogen bonding moieties. The receptor 1 is found to have considerable binding affinity for weakly basic anions even in polar solvent such as DMSO. In addition, receptor 1 is selective for nitrite. The experimental data from UV-vis, fluorescence and H-1 NMR titration are consistent with theoretical studies. The order of the interaction of the C-H groups of perimidine containing receptor with NO2- anion is found to be perimidine (C-H)>methylene (C-H)>methyl (C-H)>anthracene (C-H). 0 2015 Elsevier Ltd.

Mixing at low Reynolds numbers, especially in the framework of confined flows occurring in Hele-Shaw cells, porous media, and microfluidic devices, has attracted considerable attention lately. Under such circumstances, enhanced mixing is limited due to the lack of turbulence, and absence of sizable inertial effects. Recent studies, performed in rectangular Hele-Shaw cells, have demonstrated that the combined action of viscous fluid fingering and alternating injection can dramatically improve mixing efficiency. In this work, we revisit this important fluid mechanical problem, and analyze it in the context of radial Hele-Shaw flows. The development of radial fingering instabilities under alternating injection conditions is investigated by intensive numerical simulations. We focus on the impact of the relevant physical parameters of the problem (Peclet number Pe, viscosity contrast A, and injection time interval Delta t) on fluid mixing performance.

The present invention provides a method for manufacturing platinum nanoparticle solution and a self-assembled platinum counter electrode thereof. The present invention adopts a polyol reduction method and controls the reduction reaction periods under various pH conditions. After the platinum nanoparticle dispersion solution of uniformly distributed platinum nanoparticles having small sizes is produced, the self-assembled platinum nanoparticles are adsorbed on a functionalized surface of a conductive substrate by dip coating at the normal temperature. Therefore, the structure of a platinum nanoparticle monolayer is formed, to obtain the self-assembled platinum counter electrode with a homogeneous single layer on the surface. This process is much simpler without adding any stabilizers or surfactants, without involving any subsequent heat treatments, and it consumes less amount of the platinum material. By employing the present invention for commercialization, the cost of mass production for the dye-sensitized solar cell application is thus reduced.

A semiconductor device and methods of formation are provided. The semiconductor device includes a first metal alloy over a first active region of a fin and a second metal alloy over a second active region of the fin. A conductive layer is over a channel region of the fin. A semiconductive layer is over the conductive layer. The conductive layer over the channel region suppresses current leakage and the semiconductive layer over the conductive layer reduces electro flux from a source to a drain, as compared to a channel region that does not have such a conductive layer or a semiconductive layer over a conductive layer. The semiconductor device having the first metal alloy as at least one of the source or drain requires a lower activation temperature than a semiconductor device that does not have a metal alloy as a source or a drain.
