Abstract: The invention relates to an end product for air-conditioning indoor unit, which comprises a heat exchange tube through which air and refrigerant exchange heat; a heat exchange fin on which a tube hole for passing through the heat exchange tube is formed and the surface of which is coated with a hydrophilic coating containing photocatalytic material; and an ultraviolet lamp arranged at or near the heat exchange fin, so that the ultraviolet light of the ultraviolet lamp can cover the surface of the heat exchange fin coated with the hydrophilic coating. The invention further provides an air-conditioning indoor unit configured with the end product and a method for coating heat exchange fins of the end product. The end product for air-conditioning indoor unit according to the invention can achieve highly efficient air purification.

Abstract: The present disclosure relates to a nano-cubic polyanionic electrode material, a preparation method therefor, and use thereof. The electrode material of the present disclosure comprises NasV2(PO4); @M; where M is a block polymer containing disulfide bond; further, a nano-cubic NVP@M@PDA material can be formed by using coupling between PDA and NVP. The conductivity performance and cycle performance of the material obtained in the present disclosure are greatly improved, and the present disclosure well solves the problems associated with matching with a hard carbon negative electrode.

Abstract: Systems, methods, and other embodiments associated with monitoring business transactions are described. In one embodiment, a computer-implemented method comprises tracking calls made from a first component to other components in a distributed application wherein the calls are part of processing a business transaction. Aggregate metrics are collected and instance metrics are collected for each of the calls made and a time spent for processing the calls. The method identifies and selects N calls that consumed the most time based on the time spent for processing each call. The instance metrics for the selected N calls and the aggregate metrics are reported to a monitoring server, while the instance metrics from unselected calls are discarded.
