Abstract: The present disclosure relates to a device for and a method of interfacial electrofabrication of freestanding biopolymer membranes comprising at least one anode; at least one cathode; at least one anode electrolyte; and at least one cathode electrolyte, wherein at least a portion of the at least one anode electrolyte and the at least one cathode electrolyte form an interface, wherein at least one polyelectrolyte complex membrane (PECM) forms at the interface of the at least one anode electrolyte and the at least one cathode electrolyte, wherein the at least one anode electrolyte and the at least one cathode electrolyte are separated by the PECM, wherein the at least one anode is disposed in the at least one anode electrolyte, wherein the at least one cathode is disposed in the at least one cathode electrolyte, and wherein the at least one anode and the at least one cathode are distal from the interface of the at least one anode electrolyte and the at least one cathode electrolyte.

Abstract: This invention provides a long-lasting artificial cell membrane with a prefabricated, freestanding biopolymer hydrogel as the cytoskeleton that is partially tethered to and supports lipid bilayer for high stability. The highly stable lipid bilayer has unrestricted fluidic, optical and electrical accesses to both sides of the lipid bilayer, which has significant impact on fundamental biological studies and advanced pharmaceutical industries.

Abstract: The present disclosure relates to a device for and a method of interfacial electrofabricatio of freestanding biopolymer membrane.

Abstract: A cloud recording system, a cloud recording server, and a cloud recording method are provided. The cloud recording system includes an image source device, a recording device, and a remote storage device. The image source device provides an audiovisual streaming data. The recording device is used for receiving the audiovisual streaming data. The recording device stores at least one recording time parameter and includes a capture unit and a conversion unit. The capture unit is used for capturing a partial audiovisual streaming data in accordance with the recording time parameter. The conversion unit is used for converting the partial audiovisual streaming data into a captured file. The recording device is configured to transmit the captured file to the external of the recording device. The remote storage device is connected to the recording device and is used for receiving and keeping the captured file.
