Pivalic acid (PVA) was used as a new coadsorbent to dyesensitized solar cells (DSCs) to modify the interface between the TiO2 films and electrolyte. The addition of PVA improved the light-to-electricity conversion efficiency of devices by 8% by enhancing t ...
Al2O3 thin films were deposited by a metal organic chemical vapour deposition on InAIN/GaN heterostructures using Ar or NH3 as a carrier gas. Effects of NH3 and Ar carrier gases on the electrical and structural properties of Al2O3/InAIN/GaN HEMT devices we ...
The Helimak experiment produces a toroidal plasma with a helical magnetic field. A simulation-experiment comparison of turbulence in this device is presented, focusing on parameter regimes in which the turbulence is dominated by interchange modes with k(pa ...
The performance of popular molecular mechanics (MM) force fields in treating problems that involve ion-channel interactions is explored. We have used quantum mechanical/molecular mechanical (QM/MM) calculations to compute the electrostatic potential inside ...
The solar-to-elec. power-conversion efficiency (η) of dye-sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle-based, one-dimensional photonic crystal as a coherent scattering layer in the device. The photogenerated curr ...
Two novel trialkylsilyl-containing organic sensitizers (JK-53 and JK-54) have been designed and synthesized. Nanocrystalline TiO2-silica-based dye-sensitized solar cells (DSSCs) were fabricated using these dyes. Under standard global AM 1.5 solar condition ...
We revisit the asymptotic formulas originally derived in [D.J. Cedio-Fengya, S. Moskow, M.S. Vogelius, Identification of conductivity imperfections of small diameter by boundary measurements. Continuous dependence and computational reconstruction, Inverse ...
Humans and animals learn by modifying the synaptic strength between neurons, a phenomenon known as synaptic plasticity. These changes can be induced by rather short stimuli (lasting, for instance, only a few seconds), yet, in order to be useful for long-te ...
This paper presents a solar charger ASIC for Nickelbased (NiCd or NiMH) batteries. The system is fully integrated and no external component is needed. The ASIC includes a voltage reference, a low-impedance switch, an oscillator, a poweron reset, and a digi ...

The realization of a vertically moving micromirror using electrostatic actuation in a comb drive configuration is presented. The micromirror is designed for the use in tunable mid-infrared Resonant Cavity Enhanced Detectors (RCEDs). It can be displaced mor ...
