Abstract: A pulsed voltage bias method and/or pulsed light bias method may be used to reduce, minimize, and/or eliminate external quantum efficiency measurement artifacts of multi-junction solar cells, for example artifacts caused by the shunt effect. In this manner, multi-junction solar cells may be designed and constructed with improved performance, efficiency, and the like.

Abstract: Systems for providing electro-mechanical sensors are provided. In some embodiments, a system for providing an electro-mechanical sensor comprising: a flexible material forming at least a first channel and a second channel, wherein the first channel includes a first plate region and the second channel forms a second plate region that is substantially aligned with the first plate region; and an electrically conductive fluid that fills the first channel and the second channel.

Abstract: Multi-band photodetectors can be formed by series connecting unipolar and, optionally, bipolar semiconductor structures, each having different photodetection bands. Under default mode of operation, the detector with highest resistance and lowest current will be the current limiting device and will be the active photodetector. When the active photodetector is illuminated with strong light in its own detection band it will be optically biased. This active photodetector will no longer be the highest resistance device, and the next photodetector will be the active photodetector. Repeating this operation pattern, allows switching photodetection bands of the multi-band photodetector. The resistances, dark current and photocurrent of the devices should be engineered to have proper switching. Moreover, the illuminating surface, and photodetector placement should be optimized for proper light biasing. The current passing through the device will always be equal to the current of the active photodetector.

Abstract: The present invention provides reagents and methods for limiting adsorptive and/or oxidative protein losses in a sample.

Abstract: The invention provides arrays of compound for use in profiling samples. The arrays include compounds bind to components of the samples at relatively low affinities. The avidity of compounds binding to components of the samples can be increased by forming arrays such that multivalent components of the samples (e.g., antibodies or cells) can bind to more than one molecule of a compound at the same time. When a sample is applied to an array under such conditions, the compounds of the array bind to component(s) of the sample with significantly different avidities generating a profile characteristic of the sample.

Abstract: Systems and methods of the present disclosure provide for three-dimensional stacks of microelectromechanical (MEMS) systems, such as sensors. The stacks may be encapsulated and sealed, and can be positioned within biological tissue, for example to monitor biological signals within the volume of the sensor, provide stimulating signals to a brain, and so forth.

Abstract: Compositions are disclosed containing a solvated viscoelastic polymeric gel diluted into an ionically conductive aqueous solution which can be usefully applied to any surface that is hydrophobic to act, for example, as an antifogging coating with minimal optical distortion and excellent transparency. The compositions can also be used as lubricious agents on medical implants, shunts, and surgical supplies to minimize tissue trauma, to maximize bio-compatibility, and to increase healing by enhancing better irrigation and flow in adjacent tissue.

Abstract: Interconnect and/or reflow methods of the present disclosure achieve high aspect ratio interconnects, for example interconnects having an aspect ratio as high as 4, in addition to wider interconnect height tolerances among interconnects (for example, interconnects having a height variability of up to about 30%) while still achieving reliable electrical connections. Moreover, flip-chip interconnects configured in accordance with principles of the present disclosure can provide improved z-axis spacing between die-to-die and/or die-to-substrate flip chip stacks, for example z-axis spacing as large as 600 ?m. In this manner, additional spacing can be achieved for MEMS devices and/or similar components that are extendable and/or deformable out of the die plane.
