Tohoku Univ. Technology : Open type Nanoporous body, surface treatment, composite : T10-043_T22-030
There are many examples such as stainless steel (austenitic and ferritic), nitinol, Si, C, Fe, W, Ti, Cr, Zr, Nb, Mo, Ta, Fe-Cr-Co-Ni-V high entropy alloy, Ni-Mo alloy, Fe-Al alloy, etc.! Depending on the application, magnesium and iron composites can also be made!
Conventionally, for porous metals (Nano-microporous metals) having micropores of nano or micrometer size, a dealloying (deconditioning) method has been used to obtain porous bodies by corrosion-removing only noble metals from alloys of noble and noble metals in aqueous solution. However, there is a problem that the target metals are limited in that it is possible to fabricate nano-microporous metals only in noble metals and their alloys with respect to the standard hydrogen electrode potential. The present invention can easily fabricate nano-microporous bodies in vulgar metals and their alloys that could not be fabricated in principle by conventional methods. As one specific example, the nano-porous bodies were successfully fabricated in pure metals such as titanium, niobium, and molybdenum, alloys such as beta titanium and stainless steel (austenitic and ferritic), and carbon.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
