Abstract: Austenitic stainless steel includes 16 to 26 wt % of chromium (Cr), 8 to 22 wt % of nickel (Ni), 0.02 to 0.1 wt % of carbon (C), 0.2 to 1 wt % of niobium (Nb), and 2 to 3.5 wt % of manganese (Mn), and has an austenite matrix, wherein a nanosized niobium carbide (NbC) is precipitated in the austenite matrix, and the nanosized niobium carbide is uniformly dispersed in the austenite matrix. The austenitic stainless steel may further include 0.5 to 1.5 wt % of molybdenum (Mo).

Abstract: A compound represented by a specific chemical formula, a core including the compound represented by the specific chemical formula, and a core-shell dye including a shell surrounding the core, a photosensitive resin composition including the compound represented by the specific chemical formula, and a color filter manufactured using the photosensitive resin composition are disclosed.

Abstract: A support member includes a variable stiffness layer including an electrorheological elastomer, a first electrode layer disposed on a first surface of the variable stiffness layer, and a second electrode layer disposed on a second surface of the variable stiffness layer different from the first surface of the variable stiffness layer.

Abstract: Disclosed is an electronic device that receives a first input received through a stylus pen connected with the electronic device through wireless communication in a lock state of the electronic device, identifies unlock history information by at least one user authentication method in response to receiving the first input, and changes a state of the electronic device to an unlock state, based at least partially on an existence of the identified unlock history information.

Abstract: An electronic device for displaying information related to a stylus pen is provided. The electronic device includes a wireless communication link, which is based on a short-range wireless communication protocol, with a stylus pen inserted into an inner space of a housing, detects that the stylus pen is detached from the housing, receives a signal including information about a battery state of the stylus pen from the stylus pen through the short-range wireless communication protocol, and displays a first graphical user interface (GUI) indicating the battery state, based at least on the information about the battery state.

Abstract: An electronic device is provided. The electronic device includes a display, a pen sensing panel disposed inside the display or on a rear surface of the display and receiving a first signal from an electronic pen through a first communication protocol, a communication circuit receiving a second signal from the electronic pen through a second communication protocol, a memory storing at least one application, and a processor electrically connected to the display, the pen sensing panel, the communication circuit, and the memory.
