Abstract: This application provides an image processing method and an electronic device, and relates to the field of image application technologies. In a scenario in which an electronic device starts a plurality of cameras for photographing, details of images or videos captured by the plurality of cameras can be enriched, to improve photographing effect of the electronic device. In the method, an electronic device may determine a target zoom ratio in response to a zoom operation input by a user, and start a second camera; and when the target zoom ratio is greater than or equal to a first preset value and less than or equal to a second preset value, both the first camera and the second camera capture image frames through overlapping exposure, and then fusion is performed on the image frames captured by the first camera and the second camera to generate a preview image.

Abstract: Three-dimensional (3D) printing of graphene materials and methods and apparatuses for making same. In some embodiments, combined metal powder and carbon growth sources (such as powder Ni and sucrose) are utilized in the 3D printing process. In other embodiments, metal powders with binders (such as powder Ni and a polymer bases binder) are utilized in the 3D printing process. The metal in the resulting 3D printed composite material can then be etched or otherwise removed yielding the 3D printed graphene materials.

Abstract: Various embodiments herein relate to methods and apparatus for etching recessed features on a semiconductor substrate. The techniques described herein can be used to form high quality recessed features with a substantially vertical profile, low bowing, low twisting, and highly circular features. These high quality results can be achieved with a high degree of selectivity and a relatively high etch rate. In various embodiments, etching involves exposing the substrate to plasma generated from a processing gas that includes a chlorine source, a carbon source, a hydrogen source, and a fluorine source. The chlorine source may have particular properties. In some cases, particular chlorine sources may be used. Etching typically occurs at low temperatures, for example at about 25C or lower.

Abstract: Methods that expand the properties of laser-induced graphene (LIG) and the resulting LIG having the expanded properties. Methods of fabricating laser-induced graphene from materials, which range from natural, renewable precursors (such as cloth or paper) to high performance polymers (like Kevlar). With multiple lasing, however, highly conductive PEI-based LIG could be obtained using both multiple pass and defocus methods. The resulting laser-induced graphene can be used, inter alia, in electronic devices, as antifouling surfaces, in water treatment technology, in membranes, and in electronics on paper and food Such methods include fabrication of LIG in controlled atmospheres, such that, for example, superhydrophobic and superhydrophilic LIG surfaces can be obtained. Such methods further include fabricating laser-induced graphene by multiple lasing of carbon precursors. Such methods further include direct 3D printing of graphene materials from carbon precurors.
