摘要:
A semiconductor or similar body used, for example, for a solar cell is examined for the physical locations of characteristics effecting its performance, such as grain boundaries, areas of relatively higher sheet resistance, bulk resistance, shortened carrier lifetime, etc. A grid array layout for conductive lines may be specifically tailored such it is positioned over less efficient photo-generative regions of the body to, for example, minimize shadowing of more efficient regions, provide a short conduction path for regions of shortened carrier lifetime, etc. The grid array layout may then be formed on the surface of the body, for example by a digital lithographic process, to accommodate cell-by-cell and/or body-by-body variations in the performance characteristics. The tailored grid array provides increased overall photo-generative efficiency of the completed solar cell.
摘要:
A sample manipulator that utilizes electrostatic traveling waves to selectively displace one or more samples deposited on its face is disclosed. The sample manipulator enables an operator to perform a wide variety of processes upon the deposited samples. Also disclosed are strategies for separating two or more samples, focusing a sample, and passing a reagent through a sample, all conducted on the face of the sample manipulator.
摘要:
In thermal sensing devices, such as for calorimetry, a support layer or central layer can have a thermometer element or other thermal sensor on one side and a thermally conductive structure or component on the other. The thermally conductive structure can conduct temperature or other thermal input signals laterally across the support layer or central layer. The temperature or signals can then be provided to the thermometer element, such as by thermal contact through the support layer. An electrically conducting, thermally isolating anti-coupling layer, such as of gold or chromium, can reduce capacitive coupling between the thermally conductive structure and the thermometer element or other thermal sensor.

A detection system includes a detection device and an anti-evaporation device. The detection device comprises a region configured to merge at least two small drops and to detect a potential transient signal generated by the merger of the drops. The an anti-evaporation is configured to enclose the region and limit evaporation from the region. A method for detecting a signal includes the following steps: depositing drops of potentially reactive chemical solutions on a detection device within a drop-merging region; placing an anti-evaporation device over the drop-merging region to form a seal around the drop-merging region; merging the drops of potentially reactive chemical solutions; and measuring a signal occurring within the merged solution drops.

A method and apparatus for measuring the presence or absence of reaction between a first and second material of interest by measuring osmotic pressure changes in a reaction cell. The reaction cell is capable of measuring the small changes in pressure that occur due to osmotic pressure shifts during a catalytic or binding reaction at species concentrations down to approximately 10−7 M.

A method and apparatus for measuring the presence or absence of interaction between at least a first and second material of interest by measuring osmotic pressure changes in an osmotic cell. Changes in osmotic pressure are determined by measuring the amount of compression exhibited by a compressible, semi-permeable material positioned in the cell.
摘要:
A method for detecting chemical reactions uses a nanocalorimeter having a substrate including thermal isolation capability residing on the substrate, thermal equilibration regions residing within the thermal isolation capability, and thermal measurement capability residing within each of the thermal equilibration regions. The thermal measurement device is connected to detection electronics. The method includes depositing drops of potentially reactive chemical solutions within the thermal equilibration region. These potentially reactive solution drops are merged through the use of drop merging electrodes residing within the thermal isolation region. The thermal change occurring within the merged solution drops is then measured with the detection electronics.
