Paint protects the outer surface of ships. The antifouling component of paint prevents aquatic organisms from attaching to the surface of the ship. However, marine paints deteriorate with time. Therefore, periodic repainting is required. Repainting i

We describe a technique to improve diamond cutting tools used in nanometer- and micrometer-scale machining and formed via focused-ion-beam (FIB) micromachining. Although FIB irradiation is an effective means of fabricating arbitrary miniature shapes

A focused ion beam (FIB) is an effective means of fabricating micro-to submicro-scale shapes on diamond cutting tools. However, ion irradiation of diamond tools causes ion implantation, defects, and non-diamond phases, all of which degrade the tool p

Tool shape is an important factor determining the shape and accuracy of machined areas in ultra-precision machining. Use of a focused ion beam (FIB) is an effective means to fabricate micro- to submicro-scale tool shapes. However, ion irradiation cau

The origin of field emission of nano-crystalline diamond/carbon nanowall (ND/CNW) films prepared by DC plasma CVD has been investigated by macroscopic field emission measurements and SEM observation. We found that there is correlation between the fie

A carbon film composed of graphite sticks as field emission (FE) points is studied using field/photoemission electron microscopy (F/PEEM) and scanning electron microscopy (SEM). The film is termed an ND/CNW film since nano-crystalline diamond is grow

The thermal desorption behaviors of highly graphitized carbon nanowalls (CNWs) and their effects on CNW field emission properties have been investigated. The hydrocarbon materials are identified to be the main contents adsorbed on CNWs, and the absor
