Abstract: Provided are a negative electrode active material including a three-dimensional composite. The three-dimensional composite includes secondary particles containing a silicon carbide-based (SiCx, 0<x?1) nanosheet having a bent portion and amorphous carbon. Also provided are a method of producing the same, and a negative electrode and a lithium secondary battery including the negative electrode active material.

Abstract: In one example, a semiconductor device comprises a substrate having a top surface and a bottom surface, an electronic device on the bottom surface of the substrate, a leadframe on the bottom surface of the substrate, the leadframe comprising a paddle, wherein the paddle is coupled to the electronic device, and a lead electrically coupled to the electronic device. The semiconductor device further comprises a first protective material contacting the bottom surface of the substrate and a side surface of the electronic device.

Abstract: Disclosed is an apparatus for controlling tint of a display panel provided on a vehicle window to adjust light transmittance depending on ambient light conditions, thereby overcoming difficulties in securing a clear view, such as glare caused by sunlight or high-beam headlamps of a vehicle in the opposite direction lane during driving. The apparatus includes: a display panel film attached to a window glass of the vehicle, and having an adjustable tint; an operation unit setting the tint of the display panel film; a detection sensor unit quantifying a change in an external environment into data; and a control unit adjusting the tint of the display panel film according to a preset program by using the data received from the detection sensor unit.
