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: Provided is a carbon fuel pneumatic dryer in which synthesis gas generated in a reactor is fed and cooled, including: a feeding part formed as a narrow pipe, via which synthesis gas and carbon fuel are fed; a drying part formed as a pipe having a larger diameter than the feeding part, in which the hot synthesis gas fed via the feeding part is cooled and the moisture content of the carbon fuel is lowered; and a conveying part formed as a pipe having a smaller diameter than the drying part such that the flow velocity of the synthesis gas and the carbon fuel having passed the drying part is increased, wherein the conveying part includes a bend so that the flow direction of the synthesis gas and the carbon fuel is changed.

Abstract: Disclosed herein is a hydrogen generating apparatus for producing hydrogen from a hydrocarbon feed through a steam reforming reaction, in which a pressure drop device is installed between a feed distributor and each of reactor tubes in order to prevent the feed from being unevenly distributed to the reactor tubes. In the hydrogen generating apparatus, the pressure drop device for artificially dropping the supply pressure of the feed is installed between the feed distributor and each of the reactor tubes which are concentrically arranged with respect to a heat source. Accordingly, if the feed is unevenly distributed, the pressure drop device can suppress an abnormal temperature rise in some of the reactor tubes to induce the smooth production of hydrogen and to greatly improve the operational safety of the hydrogen generating apparatus.

Abstract: This invention relates to a catalyst for synthesis of dimethyl ether and its preparation methods. More specifically, this invention relates to a catalyst with improved formulation for a highly efficient synthesis of dimethyl ether via dehydration of methanol. These catalysts are composed of hydrophobic zeolites, cations selected from alkali metal, alkaline earth metal, or ammonium along with alumina, silica, or silica-alumina.

Abstract: Disclosed herein are a desulfurizing agent for removing organic sulfur compounds, a preparation method thereof, and a method for removing organic sulfur compounds using the same. The desulfurizing agent consists of a copper-zinc-aluminum complex free of alkaline metal, with a large surface area. When being contacted with organic sulfur compounds, such as t-butylmercaptan, tetrahydrothiophene, dimethylsulfide, etc., the desulfurizing agent exhibits excellent desulfurization ability and is not de-graded especially at high temperatures as high as 150˜350° C.
