Abstract: Provided is a method of producing a metal-plastic multi-layered hybrid structure by using laser three-dimensional (3D) printing, the method including printing a metal structure on a substrate by using a first laser, patterning an upper surface of the metal structure by using the first laser, printing a polymer bonding layer on the patterned metal structure by using the first laser, and printing a polymer structure on the polymer bonding layer by using a second laser having a wavelength longer than a wavelength of the first laser, wherein the printing of the polymer bonding layer includes forming an intermediate phase at an interface between the metal structure and the polymer bonding layer. A layered structure produced using the above method may include the intermediate phase having the effect of an oxygen inclusion connecting a metal and a polymer.

Abstract: A stacked IC package includes a first die including a first power transmission region, an adapter die stacked on the first die, a second die stacked on the adapter die and including a second power transmission region, and a first power transmission path electrically connected between the second power transmission region and the first power transmission region through the adapter die. The first power transmission path includes a first power transmission part penetrating a portion of the adapter die in a vertical direction from the first power transmission region, a second power transmission part including a connected part in a horizontal direction from the first power transmission part in the adapter die, and a third power transmission part connected to the second power transmission region in the vertical direction from the second power transmission part. A voltage conversion circuit is arranged on the first power transmission path.

Abstract: Disclosed herein are methods for performing assays, including general functional assays, on a biological cell. Also disclosed herein are methods of barcoding the 5? ends of RNA from a biological cell and methods of preparation of expression constructs from the barcoded RNA. The barcoded RNA can encode proteins of interest, such as B cell receptor (BCR) heavy and light chain sequences. The expression constructs can be generated individually or in a paired/multiplexed manner, allowing rapid re-expression of individual proteins or protein complexes.

Abstract: Systems for operating a microfluidic device are described. The systems comprise a first surface configured to interface and operatively couple with a microfluidic device and a lid configured to retain the microfluidic device on the first surface. The lid comprises a first portion having a first fluid port configured to operatively couple with and flow fluidic medium into and/or out of a first fluid inlet/outlet of the microfluidic device and a second portion having a second fluid port configured to operatively couple with and flow fluidic medium into and/or out of a second fluid inlet/outlet of the microfluidic device. The second portion of the lid is separable from the first portion and movable between a closed position in which the second fluid port of the second portion of the cover is operatively coupled with the second fluid inlet/outlet of the microfluidic device and an open position in which a portion of the microfluidic device that contains the second fluid inlet/outlet is exposed.

Abstract: Disclosed herein is a method of manufacturing a color-controlled sapphire, comprising: vaporizing a metal material, irradiating the vaporized metal material with electron beams or high-frequency waves to form the vaporized metal material into a plasma state, and then implanting the metal ions into a sapphire by extracting the metal ions from the plasma and accelerating the metal ions (step 1); and heat-treating the sapphire implanted with the metal plasma ions in an oxygen atmosphere or in air (step 2). According to the method of manufacturing a sapphire of the present invention, a sapphire, which can exhibit various colors, can be manufactured by implanting the ions, which can cause optical band gap changes into the sapphire, and a sapphire, which cannot be damaged by radiation and can exhibit colors uniformly, can be manufactured by conducting heat treatment under an oxygen atmosphere.
