Abstract: The present disclosure relates to an apparatus for detecting microplastics based on optical technology, more particularly the present disclosure relates to an apparatus for detecting microplastics, which is capable of detecting and analyzing microplastics of various sizes that exist in a fluid in real time regardless of transparency using a microfluidic chip based on optical technology.

Abstract: A semiconductor device includes a substrate including a first device region and a second device region, a first active pattern on the first device region, a second active pattern, which has a width smaller than the first active pattern, on the second device region, a first channel pattern on the first active pattern, a first source/drain pattern connected to the first channel pattern, a second channel pattern on the second active pattern, a second source/drain pattern connected to the second channel pattern, and a gate electrode that extends from the first channel pattern to the second channel pattern in a first direction. The first channel pattern includes a plurality of semiconductor patterns, which are vertically stacked and spaced apart from each other. The second channel pattern protrudes vertically from the second active pattern.

Abstract: An atomizer and an electronic cigarette are disclosed. The atomizer includes a shell defining a smoke outlet communicating with outside environment, a liquid cavity capable of storing a fluid to be vaporized and an atomizing chamber. A heating assembly located inside the shell, wherein the heating assembly comprises a liquid guiding member, a cover and a heating component. The cover is an integral structure defining a liquid tunnel and a smoke tunnel, the liquid tunnel communicates with the liquid cavity and extends to the liquid guiding member, and the smoke outlet communicates with the atomizing chamber via the smoke tunnel. The liquid guiding member is configured to transport the fluid from the liquid tunnel to the atomizing chamber, and to heat the fluid to generate smoke. The heating component is connected with the liquid guiding member to heat the liquid guiding member.
