Abstract: The present invention relates to the field of battery, and provides a direct ethanol fuel cell and a preparation method thereof. The method comprises the steps of: synthesizing catalyst: mixing and preheating silica powder, sucrose and trithiocyanuric acid to get a mixed powder; mixing and heating the mixed powder with Teflon to get N,S codoped carbon catalyst; synthesizing electrolyte: polymerizing sodium acrylate with an initiator and soaking the resulted hydrogel in a harsh alkaline solution; preparing cathode: coating the N,S codoped carbon catalyst onto a current collector to get the cathode; preparing anode: coating Pt—Ru/C catalyst onto a current collector to get the anode; preparing the cell: clamping the soaked hydrogel between the cathode and the anode to get the cell. The resulted cell possesses remarkable flexibility and high energy density, with the function of drop-and-play.

Abstract: A derivative spectroscopy system for achieving a tunable resolution of 2 nm or less in resolving spectral components of an input optical signal is provided so as to estimate derivative spectra of the input optical signal based on the resolved spectral components. In the system, a first dispersive-element structure spectrally decomposes the input optical signal into subband signals. A second dispersive-element structure receives part or all of the subband signals and spectrally decomposes the received subband signals to plural spectral components. A material having a temperature-variant refractive index is used to build the second dispersive-element structure, enabling a shift of center wavelength of each spectral component as small as 2 nm of less upon changing a temperature of the second dispersive-element structure.

Abstract: The present disclosure relates to a method and device for processing user operations. The method includes: displaying a Graphical User Interface (GUI) for exchanging for a processing object, the GUI including a control key for confirming the exchanging for the processing object; when receiving a three-dimensional touch operation on the control key, sending a transfer instruction to a server, the transfer instruction being configured to request the server to generate an order corresponding to the processing object, and subsequently transfer a resource from a first account to a second account, to exchange for the processing object; receiving a success response from the server; and displaying a prompt indicating the success response.

Abstract: A module has switchable operation states. A first switching unit switches the module between a first operation state and a second operation state. A first interface switches between sending signals to another module which has switchable operation states and receiving signals from the other module. The first interface sends a first signal to the other module when the module is in the first operation state, sends a second signal to the other module when the module is to be switched into the second operation state, and receives signals from the other module when the module is in the second operation state. A second interface communicates with the other module. When the second interface receives a response of the other module to the second signal, the first switching unit switches the module into the second operation state. The reliability of module switching is improved in an embodiment.
