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: Embodiments of the microwave amplification system are described. In an embodiment, a microwave amplification system includes a microwave amplifier that contains a paramagnetic material with an impurity. The impurity has a plurality of nuclear spin and electron spin-based energy levels. The system includes an input to receive a pumping signal which is transmitted to the microwave amplifier to cause a population inversion in the impurity and excite it to one of the nuclear spin and electron spin-based energy levels. The system further includes another input to receive an input signal to be amplified by the microwave amplifier, the input signal having a lower power than the pumping signal. Once transmitted to the microwave amplifier, the input signal is amplified by the excited state of the impurity in the microwave amplifier thereby generating an amplified signal.

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: It is an object of the present invention to achieve rapid surface patterning of biomolecules within microfluidic devices with high reproducibility. In this work, we present a new means of creating micro- and nano-patterns of aminosilanes within microfluidic devices via an aqueous based microcontact printing technique. To minimize the diffusion of molecules into the PDMS stamp, we use water as the inking solvent and enforce short incubation and contact times during the printing process to preserve the predefined resolution of patterned features. These patterns then serve as the building block to couple multiple biomolecules in solution onto a single surface for subsequent bioassays.

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.
