Abstract: A multilayer ceramic capacitor includes a capacitor body that includes an active portion including dielectric layers and internal electrode layers that are alternately disposed, and cover portions including dielectric layers disposed on upper and lower surfaces of the active portion in the thickness direction, and external electrodes disposed on the capacitor body. The external electrodes include inner layers disposed on the active portion to be electrically coupled to at least one of the internal electrode layers, and outer layers disposed on the inner layers and the cover portions to cover the inner layers. The inner layers include a conductive metal in an amount of 95 atom % to 100 atom % based on the total amount of the inner layers. The outer layers include a conductive metal, and glass including aluminum oxide and silicon dioxide. The thickness of the inner layers is within a range from 1 ?m to 3 ?m.

Abstract: A multilayer ceramic capacitor and a method of manufacturing the same. The multilayer ceramic capacitor includes a capacitor body including a dielectric layer and an internal electrode layer; and an external electrode disposed outside the capacitor body. The external electrode includes a lower layer positioned on a cross-section of the capacitor body to be electrically connected to the internal electrode layer, and an upper layer to cover the lower layer and positioned on the lower layer. The lower layer includes a first glass including aluminum (Al) in an amount of more than 0 atom % to 8 atom % or less with respect to a total amount of components of the first glass. The upper layer includes a second glass including aluminum (Al) in an amount of 10 atom % or more to 20 atom % or less with respect to a total amount of components of the second glass.

Abstract: Sensors and methods are provided that include a diamond material containing a nitrogen vacancy center, the diamond material being configured to be exposed to an environment comprising one or more gases, an optical light source configured to excite the nitrogen vacancy center of the diamond material with an optical light beam produced therefrom, a detector configured to detect a signal originating from the diamond material in response to the optical light beam exciting the nitrogen vacancy center, and the capability of analyzing the signal to identify a specific gas in the environment. Also included are levitated spin-optomechanical systems capable of elevating in a vacuum a diamond material containing a nitrogen vacancy center, applying microwave radiation to the diamond material for controlling and flipping the electron spin of the nitrogen vacancy center, and monitoring electron spin of the nitrogen vacancy center.
