Provided is a method of manufacturing a palladium (Pd) thin film by using an electroless-plating method, the method including: manufacturing a reaction mixture by adding Pd salt and an alkaline pH regulator to an alcohol-water mixed solution; and forming a Pd thin film by loading and stirring the reaction mixture in a substrate. Accordingly, a Pd thin film having a surface enhancement Raman scattering (SERS) effect may be easily manufactured without having to use expensive additional equipment, such as a vacuum device, and in detail, electroless-plating may be performed even on an insulating substrate formed of, for example, glass. In addition, since a size of the Pd thin film manufactured on the substrate may be adjusted, the Pd thin film may be applied to various electrochemical products.

The integrity verification system includes a client and an RCE server. The client requests an RCE service to the RCE server using a pointer of a return function as a parameter of a service call function and transmits a memory code of the return function to the RCE server when Reverse-RCE for obtaining the memory code of the return function is requested from the RCE server. The RCE server generates a first hash key of the transmitted memory code, compares the first hash key to a stored second hash key of the memory code of an original return function, generates a return value according to a compared result between the first hash key and the second hash key and transmits the generated return value to the client using the generated return value as a parameter of the service call function. The client executes the return function using the return value as a parameter of the return function.

The present invention provides a method for preparing carbon nanotube fibers with improved spinning properties using a surfactant and carbon nanotube fibers prepared by the method. According to the method for preparing carbon nanotube fibers of the present invention, the addition of a surfactant during the preparation of carbon nanotubes interrupts and delays the agglomeration of catalyst particles, which reduces the size of the catalyst particles and uniformly disperses the catalyst particles that play a key role in the formation of carbon nanotube fibers, thus increasing the strength and conductivity of carbon nanotube fibers and improving the spinning properties. While convention methods prepare carbon nanotube fibers by injecting a catalytic material for the synthesis of carbon nanotubes in a high-pressure supercritical state to be uniformly dispersed, the present invention uses a dispersant and thus does not require the injection in a high-pressure supercritical state.
