Abstract: Provided is a recombinant microorganism including at least two genes for producing itaconic acid and its derived monomers, and the at least two genes are located on the same expression vector. The at least two genes include one encoding cis-aconitic acid decarboxylase and the other one encoding aconitase, and the genome of the recombinant microorganism includes a gene encoding the molecular chaperone protein GroELS. Also provided is a method for producing itaconic acid by using the microorganism.

Abstract: A semiconductor device includes a fin extending from a substrate. The fin has a source/drain region and a channel region. The channel region includes a first semiconductor layer and a second semiconductor layer disposed over the first semiconductor layer and vertically separated from the first semiconductor layer by a spacing area. A high-k dielectric layer at least partially wraps around the first semiconductor layer and the second semiconductor layer. A metal layer is formed along opposing sidewalls of the high-k dielectric layer. The metal layer includes a first material. The spacing area is free of the first material.

Abstract: A semiconductor device includes a first set of nanostructures stacked over a substrate in a vertical direction, and each of the first set of nanostructures includes a first end portion and a second end portion, and a first middle portion laterally between the first end portion and the second end portion. The first end portion and the second end portion are thicker than the first middle portion. The semiconductor device also includes a first plurality of semiconductor capping layers around the first middle portions of the first set of nanostructures, and a gate structure around the first plurality of semiconductor capping layers.

Abstract: An air sterilizing device has a casing, a wheel disc covered with microporous structures, a blower, and a sterilizing module. The casing has an air inlet and an air outlet. The blower located in the casing introduces the external air from the air inlet, and the external air is filtered and sterilized by the wheel disc and the sterilizing module. The filtered and sterilized air is discharged from the air outlet. The sterilizing module locates next to the wheel disc for sterilizing the air flowing through the sterilizing module and also for sterilizing the wheel disc by the relative rotation between the wheel disc and the sterilizing module. Bacteria and viruses attached to the wheel disc are eliminated, and the filtration and sterilization functions of the wheel disc are maintained. The efficacy and the efficiency of the air sterilizing device are therefore improved.

Abstract: A method for treating a virus infection in a subject is provided. The method comprising administering to the subject in need an effective amount of a derivative of aniline selected from the group consisting of a compound of formula (I), a pharmaceutically acceptable salt of the compound of formula (I), a pharmaceutically acceptable ester of the compound of formula (I), and combinations thereof: wherein, R1 is C1 to C10 alkyl; R2 is H or C1 to C4 alkyl; and R3, R4, R5, R6 and R7 are independently H, —OH, halogen, C1 to C10 alkyl, C1 to C10 alkoxyl, or (C1 to C10 alkylene)-O—O—(C1 to C10 alkyl).
