    摘要： A nanocalorimeter includes a merging layer having, a drop placement area for holding drops to be merged and a thermal equilibration area. A measurement layer includes a substrate, and a temperature probe on the substrate, wherein the temperature probe extends out of the surface of the substrate to come into operative contact with the thermal equilibration area when the measurement layer is placed in operative association with the merging layer. The nanocalorimeter is configured to have the merging layer and the measurement layer non-integrated, making the measurement layer reusable.

    摘要： A method and device for merging and mixing at least two separate and distinct fluid drops on a substrate, includes a drop merging area on the surface, where a first magnetic material is placed at a first location. A first drop of fluid is then placed at the first location on the surface, resulting in the first magnetic material being at least partially positioned within the first drop of fluid. A second drop of fluid is then placed at a second location on the surface of the drop merging area. A magnetic field is applied by a varying magnetic field generator to at least a portion of the drop merge area of the substrate, which includes at least the first location on the substrate. The varying magnetic field will act on the first magnetic material to move the first magnetic material within the first drop of fluid, causing a stirring of the fluid. A drop merging force from a drop merging mechanism is applied to at least one of the first drop of fluid and the second drop of fluid within the drop merge area. This causes at least one of the first drop of fluid and the second drop of fluid to move toward the other and make contact. The internal stirring of the fluid in the first drop of fluid by the movement of the magnetic material enhances the mixing of the constituents of the first drop of fluid and the constituents of the second drop of fluid.

    摘要： A layered structure can be formed having immobilized or segregated pH buffering groups that can be used to separate carbon dioxide or other gases. The pH buffering groups can be immobilized within a matrix, confined within a gel, or segregated by a semi-permeable membrane. The pH buffering groups can be configured to increase the efficiency of the system by maintaining a desirable pH profile within the cell and to permit the flow of the carbon-containing ions within the system while controlling diffusion of protons and/or hydroxyl ions.

    摘要： 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.

    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.
