Abstract: The present disclosure provides a self-driven water collecting surface having a superhydrophilic-superhydrophobic structure, and a method for preparing the same, belonged to the technical field of water harvesting and superhydrophobic surfaces. The water collecting surface is a superhydrophobic surface with the distributed superhydrophilic region. The superhydrophilic region is a venation channel network structure consisting of hierarchical superhydrophilic channels. In the method, a pulsed laser is firstly adopted to form periodically distributed peak-pit microstructures and nanostructures, which is then modified with a low-surface-energy substance. Then, the low-surface-energy substance layer is removed by a pulsed laser again according to a venation channel network pattern. The laser scanned region is superhydrophilic, while the other regions are superhydrophobic. So that, the self-driven water collecting surface with the superhydrophobic-superhydrophilic structure is obtained.

Abstract: Systems, methods, devices, instructions, and media are described for generating suggestions for connections between accounts in a social media system. One embodiment involves storing connection graph information for a plurality of user accounts, and identifying, by one or more processors of the device, a first set of connection suggestions based on a first set of suggestion metrics. A second set of connection suggestions is then identified based on a second set of suggestion metrics, wherein the second set of connection suggestions and the second set of suggestion metrics are configured to obscure the first set of connection suggestions, and a set of suggested connections is generated based on the first set of connection suggestions and the second set of connection suggestions. The set of connection suggestions is then communicated to a client device method associated with the first account.

Abstract: A double-layer coiled tubing double-gradient drilling system, on the basis of conventional drilling equipment, includes a double-layer coiled tubing system, separating fluid, a downhole lifting pump system, throttling control systems and a data monitoring system. Power fluid enters an annular space of the tubing through an adapter, passes through a downhole lifting pump, enters an inner pipe through a bridge channel, and enters the bottom hole through the drill bit. Return fluid enters an annular channel of the tubing through a recovery hole, then enters the inner pipe through the bridge channel and enters the lifting pump, and then enters a solid control system through the adapter and the control systems in sequence. Gradient control of the bottom hole pressure is realized through monitoring of the separating fluid and control of the drilling pump unit and throttling control systems.
