Abstract: The method for preparing fluorine-doped lamellar black TiO2 nanomaterials includes mixing a solution of tetra-n-butyl titanate, n-propanol and hydrofluoric acid together, and then stir the solutions for a period of time. The solution is transferred into an autoclave and reacts at a certain temperature for a period of time. The sample obtained by the reaction is washed and dried. Then, the sample is heated in a protective atmosphere for a period of time so as to produce the fluorine-doped lamellar black TiO2 nanomaterials. This fluorine-doped lamellar black TiO2 owns superior optical absorption and electron transport performances.

Abstract: Disclosed are a method and device for displaying chat messages in a live broadcasting application. A local region of an interface of the said live broadcasting application is pre-set to have a sliding layout area for displaying a chat message, comprises: receiving chat messages via a message receiving ingress provided by the said live broadcasting application; and displaying each of the received chat messages in the said sliding layout area in sequence according to the order of receipt of the chat messages.

Abstract: Disclosed are a method and electronic apparatus of implementing voice interaction in a live video broadcast. The method includes: enabling a voice collection module when a continuous touch event occurring on a voice response control item in an interactive information page is detected; collecting voice data by voice collection module during the continuous touch event, and the live video broadcast page staying at muted state when the voice collection module collects the voice data; sending the voice data to an interaction platform so that the interaction platform pushes the voice data to each related user, wherein the related users comprise a user watching live video and a user broadcasting live video. The application resolves the technical problem at the present stage where applications of live broadcast permitting text type interaction lack timeliness, sufficient immediateness and friendliness.

Abstract: A method and a mobile client for realizing two-person simultaneous live video are provided in the disclosure. The method is adaptive to an inviter of two-person live video, and includes following steps: sending, in a first video window, a live broadcast invitation to an invitee, the first video window being provided by a first player; receiving live video data sent from the invitee and starting a second video window to play the live video data after receiving a response from the invitee, the second video window being provided by a second player; wherein the first video window and the second video window are displayed simultaneously, a size of the second video window is different from a size of the first video window.

Abstract: A 3D video recording device, a 3D video processing method, and an electronic device, are provided wherein the recording device includes a camera and further includes: a baffle located in the middle of the camera and vertical to the camera; a first reflective mirror, and a second reflective mirror parallel to the first reflective mirror and used to receive light reflected by an object in front of the camera and reflect the light to the first reflective mirror, so that the first reflective mirror further reflects the light to the camera; and a second reflective mirror group located at the other side of the baffle including: a third reflective mirror disposed symmetrically to the first reflective mirror with respect to the baffle and a fourth reflective mirror disposed symmetrically to the second reflective mirror with respect to the baffle.

Abstract: The present application provides a method and a mobile client for implementing live streaming of multimedia through an external device. The method includes: concurrently enabling a connection of a wireless local area network and a connection of a mobile network; connecting to the external device through the wireless local area network provided by the external device having a function of multimedia shooting; receiving a multimedia data stream sent by the external device through the wireless local area network, wherein, the multimedia data stream is obtained from a real-time shooting of the external device; sending the multimedia data stream to a server of multimedia live streaming through the mobile network. The present application solves the current problems of effects caused by a narrow scope of shooting and poor qualities of live streaming on users' experiences.
