Abstract: A membrane is provided herein having the ability to remove/prevent membrane fouling. This novel membrane consists of a thin electrically conductive layer deposited on the membrane surface. This unique membrane can be used as an electrode in an electrochemical system that consists of the membrane, the salty water as an electrolyte and a counter electrode that can be inserted in the saline feed solution. A periodic electrolysis can be performed. Electrolysis will generate gases (e.g., Cl2 and O2) and the periodic gases evolution at the membrane surface acts to clean and prevent both fouling and scaling of the membrane surface. The new system enables on-line self-cleaning mechanism of the membrane, which is useful for, inter alia, use of such a membrane in a system for the desalination of saline water or wastewater.

Abstract: A method for switching communication connection modes, a communication system, a base station, a transmitter and a receiver are provided. The method includes the following steps. Firstly, when a base station or a core network entity determines that a communication mode between a transmitter and a receiver should be switched from a cellular communication mode to a device-to-device communication mode, the base station sends a control message to the transmitter. Next, the transmitter stops transmitting at least one first packet to the base station in response to the control message. Afterwards, the receiver receives at least one transmission-unfinished packet and a transmission-unfinished packet status related to the at least one transmission-unfinished packet forwarded by the base station.
