Abstract: The present disclosure provides a method of preparing graphene quantum dots by intercalation of graphite nanoparticles and continuous exfoliation in an aqueous solution. The preparation method has a short process time and uses graphite nanoparticles of several nm as a reactant. Thus, graphene quantum dots prepared by the preparation method are uniform in size and shape with minimized defects and improved electrical properties.

Abstract: The present disclosure relates to a method for amplification and quantitation of a small amount of mutation using a molecular barcode and a blocking oligonucleotide.

Abstract: A keypad mouse computer peripheral device of the present disclosure includes a housing on top of which is located a keypad having a number keypad. The input device has at least one clicker button operable by a user's thumb while the user's hand rests on a provided palm rest or wrist rest. Force exerted by the base or palm portion of an operating hand moves the present input device which permits the index, middle and ring fingers to be located on the 4, 5, 6 key positions of the number keypad. This maintenance of the resting or home position even while the user is engaged in movement of the present keypad mouse permits easy and fast entry of numbers. A position sensor on the bottom surface of the housing of the disclosed keypad mouse detects relative location information for positional information input for a computer's graphical user interface.

Abstract: A keypad peripheral device of the present disclosure includes a housing on top of which is located a keypad having a numeric keypad, function keys, Tab key, and right click key. The function keys may be F2 or F4 or both F2 and F4. Alternatively, F8 function key and/or directional keys may additionally be included. The present keypad peripheral device may further include the following keys: home, end, page up, and page down keys, and alternatively further comprise a back space or delete key or alt and control keys. Alternatively, at least one key of the keypad has a height that is less than at least another key of the keypad and this may be to avoid inadvertent contact with a finger or base of an operating hand. Further, an on/off switch may be provided on a bottom surface of the housing of the present computer peripheral device.
