Disclosed herein is a method for preparing ultrathin silver nanowires. It may comprise (a) dissolving a silver salt (Ag salt) and a capping agent in a reducing solvent to give a mixture solution; (b) adding a halide compound to the mixture solution to yield a silver seed; (c) heating the mixture solution and then allowing the heated mixture solution to grow ultrathin silver nanowires from the silver seed under a pressure in an inert gas atmosphere; and (d) cooling the mixture solution in which the ultrathin silver nanowires have grown, followed by purification and separation to obtain the ultrathin silver nanowires. The silver nanowires are restrained from growing in thickness under a certain pressure, so that they are 30 nm or less in thickness and have a narrow diameter distribution, which leads to an improvement in aspect ratio.

Disclosed herein is a fixed mouse. The fixed mouse includes a housing which has an insert depression, a movable body, a portion or the entirety of which is inserted into the insert depression, a direction sensing means which detects a direction in which an external force is applied to the movable body and generates a signal used to move a pointer in a corresponding direction, and speed sensing means which detects the intensity of the external force applied to the movable body and generates a signal to vary the speed of the pointer in response to the intensity of the external force. As such, the direction sensing means for moving the pointer and the speed sensing means for controlling the speed of the pointer are independently provided. Therefore, the production, maintenance and repair of the direction sensing means and the speed sensing means can be facilitated. Furthermore, the degree of design freedom for layout of a product is increased. Moreover, the fixed mouse may be configured such that a user selectively uses the function of controlling the speed of the pointer, thus making it convenient for the user.
