Lecture entilted: Graphene-wrapped zeolite membrane for rapid air separation: Superiority of intrinsic graphene oxide and control of 2D nanochannel will be given by prof. Hayato Otsuka from Shinshu University, Japan.
Faculty Library at noon.
Abstract: Energy-friendly separation method has been requested to construct a sustainable society. We have developed an ultra-high-speed gas separation membrane called graphene-wrapped MFI zeolite membrane. The graphene-wrapped MFI zeolite membrane separates gas molecules via interfacial nanochannels between the zeolite crystal and the graphene sheet, exhibiting superior gas separation properties. Control of the surface property of unstable GO is an important factor to achieve the high separation performance.
We are honored to invite you to a special guest lecture by Prof. Hayato Otsuka, a distinguished specialist in nanotechnology and materials science from Shinshu University, Japan.
