Abstract: A system and method of nanoparticle deposition for achieving an acetone sensitive response based on ruthenium decorated CuO nanowires at temperatures of 200° C. and 250° C. is disclosed. This method is useful for building sensors. The method used to build the sensor is easily integrable into silicon technology broadly, and into a CMOX compatible device specifically. Additionally, it is expected that this method of nanoparticle deposition can be transferred to other MOx nanowire sensors, such as but not limited to zinc oxide nanowire.

Abstract: A system and method for assessing performance of a plurality of perovskite optoelectronic devices are disclosed. The system comprises a chamber, a light source, a switch board for allowing selection of a device among a plurality of devices in the chamber for measurement; a DC voltage supply for applying voltage to the device, a source/measure unit (SMU) for measuring current of the device; and a computer implemented with a software program including computer executable instructions to control at least the SMU, the DC voltage supply, the switch board, and the light source. The computer-implemented method for the performance assessment by using the system includes obtaining at least one of first current-versus-voltage (I-V) data according to a first procedure and second I-V data according to a second procedure for analyzing hysteresis behavior of the device.

Abstract: A system for determining (a) forecast error and/or (b) scaling error for wind power generation is provided, the system utilizing generated and forecast time series for power generation derived from wind and analyzing temporal correlations in the wind fluctuations to quantify: (a) the forecast error defined by deviations between the high frequency components of the forecast and generated time series, and (b) a scaling error defined by a degree that temporal correlations fail to be predicted for an accurate predictor of wind fluctuations. Wind fluctuations may exhibit multi-fractal behavior at the turbine level and/or may be rectified to a fractal structure at the grid level. A memory kernel may be used to reduce the forecast and scaling errors.

Abstract: A method of forming a perovskite film is provided, the method comprising inducing a chemical reaction between a metal halide compound and methylamine (CH3NH2) gas. Specifically, the method includes: forming a metal halide film on a substrate; and exposing the metal halide film to the methylamine (CH3NH2) gas for inducing the chemical reaction between the metal halide compound and the methylamine (CH3NH2) gas to form a perovskite film. Post treatments can be carried out by adding a step of exposing the perovskite film to hydriodic acid (HI) gas and methylamine (CH3NH2) gas sequentially or simultaneously.

Abstract: A disclosed insert for a circular-shaped petri dish can generate a substantially uniform electric field across the petri dish that is filled with a fluid establishing a salt bridge. The insert includes a circular-shaped bottom plate defining a circular-shaped space; a side channel vertically erecting from a circular periphery of said bottom plate; and a pair of current rectifying chambers each having a generally planar shape communicating with the side channel. In at least some aspects of the invention, portions of the side channel bridging the pair of current rectifying chambers each have a generally concave top profile having a lowest point at the center between the pair of current rectifying chambers such that, when the salt bridge is established, the circular-shaped space defined by the bottom plate exhibits a substantially uniform electric field in a substantially entire area of the space.

Abstract: A system and method for fabricating a perovskite film is provided, the system including a housing for use as a CVD furnace having first and second sections coupled with first and second temperature control units, respectively. The first and second sections correspond substantially to the upstream and downstream of gases, respectively. One or more substrates are loaded in the second section and controlled by the second temperature control unit, and an evaporation unit containing an organic halide material is loaded in the first section and controlled by the first temperature control unit. Each of the substrates is pre-deposited with a metal halide material. The inside of the housing is pumped down to a low pressure.
