Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: A method for manufacturing an electronic device including a semiconductor memory may include forming a first carbon electrode material, surface-treating the first carbon electrode material to decrease a surface roughness of the first carbon electrode material, and forming a second carbon electrode material on the treated surface of the first carbon electrode material. The second carbon electrode material may have a thickness that is greater than a thickness of the first carbon electrode material.

Abstract: There is provided an additive, containing magnesium silicate, for a secondary battery electrolyte and a preparation method therefor. The magnesium silicate has a mass ratio of 50 to 70 wt % of oxygen (O), 5 to 20 wt % of magnesium (Al), and 15 to 35 wt % of silicon (Si). The magnesium silicate has a surface area of 50 to 500 m2/g. The magnesium silicate has a pore size of 0.1 to 20 nm.

Abstract: There is provided an additive for secondary battery electrolyte, containing aluminum silicate. The aluminum silicate has a particle size of 200 nm to 20 ?m. The aluminum silicate has a mass ratio of 60 to 70 wt % of oxygen (O), 0.1 to 2.0 wt % of aluminum (Al), and 25 to 35 wt % of silicon (Si). The aluminum silicate has a surface area of 50 to 1,000 m2/g. The aluminum silicate has a pore size of 0.1 to 20 nm.

Abstract: Provided is a method of detecting microbial colonies, the method including: irradiating light having coherence to a sample unit in which a sample is accommodated; detecting, by an image sensor, transmitted light passing through the sample unit to obtain a sample image in a time-series manner; analyzing the sample image by a controller after a preset time to determine the concentration level of colonies in the sample; and obtaining a spatial correlation of the coherence pattern of the sample image when the concentration level determined by the controller is a high concentration that is equal to or greater than a preset reference value, and determining information about the concentration of colonies in the sample based on the change of the spatial correlation of the coherence pattern over time.

Abstract: Disclosed are goggles. The goggles are provided so that they comprise: a main body unit worn on the face of a user; a lens unit that is coupled to the main body unit and has a fastening protrusion formed to protrude toward the main body unit; and a fastening unit that has a fastening recess formed therein and is coupled to the main body to lock and unlock the fastening protrusion, wherein the fastening unit includes a body part movably coupled to the main body unit and a guide protrusion for guiding the moving direction of the body part, the main body unit has a guide hole formed at a position corresponding to the guide protrusion, the guide protrusion being received in the guide hole, and the fastening unit further included a protrusion part coupled to the body part to push the fastening protrusion outward such that the lens unit is separated from the main body unit when the fastening protrusion is unlocked according to the movement of the body part into the main body unit.
