Abstract: A non-metallic semiconductor quantum dot is provided with a non-metallic substrate, and has a particle size ranged from 0.3 to 100 nm. A method of carrying out a chemical reaction or a photoluminescence reaction by using the non-metallic semiconductor quantum dot is also provided. A redox reaction of a target sample is carried out, an active substance is generated, or an electron-hole pair is produced from the non-metallic semiconductor quantum dot by providing the non-metallic semiconductor quantum dot with a predetermined energy. Photons are released by the combination of the electron-hole pair so as to perform the photoluminescence reaction.

Abstract: A system for producing a tissue-engineered material includes a hollow member and a mechanical stimulating unit. The hollow member is adapted to be implanted in a peritoneal cavity, and is to be positioned in the peritoneal cavity in a manner that a part of the hollow member contacts an inner wall surface of the peritoneal cavity for enabling formation of a biological tissue that encapsulates the hollow member. The mechanical stimulation unit is coupled to the hollow member and configured to provide a periodic mechanical stimulus to the biological tissue by periodically causing the hollow member to expand and contract. A method for producing the aforesaid tissue-engineered material is also disclosed.

Abstract: A method for modifying properties of graphene includes a graphene film provision step and a modification step. In the graphene film provision step, a graphene film is provided, and the graphene is formed on a substrate. In the modification step, the graphene film is placed in a vacuum environment and radiated by an electron beam to obtain a graphene material.

Abstract: A method for manufacturing a graphene layer includes performing a sputtering process to form a graphite layer on a substrate, and performing a lithography process on the graphite layer for thinning the graphite layer and thereafter making the graphite layer thinned to become a graphene layer.

Abstract: A foldable electronic device includes a first body, a second body, a pivot element and a loudspeaker. The pivot element is pivotally connected between the first body and the second body, and the loudspeaker is disposed in the pivot element and is capable of protruding out of a side of the pivot element.

Abstract: A keyboard module for avoiding accidental operation keyboard module includes a key unit. The key unit has a pressing portion and a contacting portion. The pressing portion abutted the casing for the key unit not being pressed down. The pressing portion can be raised up to form a pressing distance relative to the casing via a push element controlled by a controlling switch to provide the pressing function. Therefore, the keyboard module can effectively prevent the users accidentally striking unnecessary keys during their operations or when the computer is in a power saving mode.
