The present invention provides a novel approach for controlling the temperature of biological samples on a support structure. The support structure may, for instance, be a flow cell through which a reagent fluid is allowed to flow and interact with biological samples. A thermoelectric heat exchange device, such as a Peltier device, may be used to heat or cool the biological samples on the support structure. In addition, a fluid circulating heat exchange device, such as a water heating or cooling system, may be used to heat or cool the thermoelectric heat exchange device. In general, the support structure may be located on top of the thermoelectric heat exchange device which, in turn, may be located on top of the fluid circulating heat exchange device. The thermoelectric heat exchange device and fluid circulating heat exchange device may be integrated into a holder bench which may be part of a station within an imaging processing system. The holder bench may be configured to hold multiple support structures at a time. In addition, the support structures may be configured to be evaluated and imaged using both epifluorescent and total internal reflection (TIRF) excitation techniques.

The device is structured to avalanche uniformly across the entire central part (active area) such that very high currents can flow while the device is reversely biased. Forcing the device to avalanche uniformly across designated areas is achieved in different ways but consistently in concept, by creating high electric fields where the device is supposed to avalanche (namely the to active area) and by relaxing the electric field across the edge of the structure (namely in the termination), which in all embodiments meets the conditions for an increased reliability under harsh environments.

• subjecting the coated support to thermoforming for formation of an intermediate layer; and
• applying, to the intermediate layer, heat-sensitive recording-related components which contribute to color formation by heat, for formation of a heat-sensitive recording layer.

The invention provides high-temperature heat-response bentonite and a preparation method thereof, and a high-temperature heat-response bentonite drilling fluid. A high-temperature heat-response bentonite core is a rigid bentonite particle, and the exterior of the high-temperature heat response bentonite core is a flexible high-temperature heat-response molecular brush. The preparation method comprises the following steps: activating bentonite with an acid, drying, carrying out ATRP modification, rinsing and drying to obtain the high-temperature heat-response bentonite. The modification methodcomprises the following steps: mixing activated bentonite and a (3-aminopropyl) trimethoxysilane (ATMS) and methanol solution, carrying out magnetic stirring to provide a modified activation site, adding dichloromethane (containing (v/v) piperidine) and 2-bromoisobutyryl bromide to carry out ATRP modification, and meanwhile, adding phenyl methacrylate and p-xylene (copper bromide and N, N, N', N '', N '''-pentamethyldivinyl triamine), and stirring under nitrogen protection.

The invention provides a Stirling engine and a heat exchange method thereof. The Stirling engine comprises a crank shaft, expansion cylinders, compression cylinders, a heat exchanger and an air cooler. The heat exchanger comprises a heat cavity, multiple work medium cavities and multiple rotation columns. Cold and hot work mediums are in mutual countercurrent flow, and the heat cavity and the workmedium cavities at least share the outer side wall of the same rotation column as the respective inner wall. The air cooler comprises a first cooling channel. The expansion first cylinder and the first compression cylinder can be alternately compressed when the crank shaft rotates. Working work mediums perform surface heat exchange in the work medium cavities and do not need to be filled with heat retainer materials, and a heat storage and release function of a heat regenerator can be achieved. The situation is avoided that due to too small gaps of heat retainers, the flow resistance of the work mediums is large, and multiple problems are caused. High-temperature hot air energy is sufficiently used through countercurrent flow heat exchange. The heat exchange method of the Stirling engineis suitable for heat exchange of the Stirling engine under a high-temperature environment and achieves high comprehensive heat efficiency.
