Abstract: The present invention relates to a method for preparing a core-gap-shell nanoparticle having an average height of 0.1 nm to 10 nm, in which a Raman-active material is disposed between a core and a shell, and more specifically, to a method for preparing a core-gap-shell nanoparticle, which comprises introducing a shell made of an alloy of a second metal and a third metal, on the core particles of the first metal, the surface of which is modified with a Raman-active material; selectively removing the second metal by treating with a second metal etchant, followed by dealloying; the core-gap-shell nanoparticle prepared by the above method comprising a Raman-active material disposed in the gap, and uses of the core-gap-shell nanoparticle for biosensing and/or bioimaging.

Abstract: A relay temperature measuring device is provided. The device includes a sensor that measures an output of a battery and generates output measurement information and one or more relays that are disposed on a conductive line between the battery and a load. Additionally, a controller compares a relay temperature calculated using both-end measurement power information generated by measuring both ends of a conductor in a vehicle and the output measurement information with a preset temperature reference value, and connects or disconnects the relays based on a comparison result.

Abstract: A pitch walk inspection method includes obtaining a scanning electron microscope (SEM) image for a line and space (L/S) pattern formed by a multi-patterning technology (MPT), where L/S pattern includes a plurality of lines and spaces that are alternately arranged; detecting a main pitch of the L/S pattern in the SEM image; dividing a graph of the main pitch into graphs of component pitches, based on the MPT; performing a Fast Fourier Transform (FFT) on each graph of the component pitches; multiplying a phase and an intensity graph of the FFT of each of the graphs of the component pitches with each other and obtaining compensated FFT phase graphs; and calculating a pitch walk for the L/S pattern by obtaining differences between phase peak values of the compensated FFT phase graphs.

Abstract: Provided is a system for processing a substrate. The system for processing the substrate includes a process tube configured to provide a processing space for the substrate and an exhaust module connected to an exhaust port of the process tube to exhaust process residues within the processing space to the outside. The exhaust module includes an exhaust tube connected to the exhaust port, a sealing case configured to accommodate at least a portion of the exhaust tube, and a local exhaust part provided in the sealing case to exhaust the inside of the sealing case.
