Industrial research in academic institutes can be defined as a collaborative project between a corporate and an academic research laboratory. Typically, research and development projects in universities aims for the longer-term activities in science and technology. This opportunity provides students to gain a unique industrial experience ahead of the time. In addition, the firm can find their perspective valuable assets and gain competitiveness in field. This positive relationship can contribute for the ‘better’ future of all mankind.

Stainless steel shows a great resistance against corrosion, stain, and rust. This beneficial aspect provides its wide use in a number of fields. The production process requires a scaling process commonly with (H2SO4, HCl)/HF/H2O2 scaling acids. Among these scaling acids, hydrofluoric acid (HF) is the most conventionally applied acid. However, HF is a corrosive, a ‘high-risk’ contact poison, and environmentally harmful. Thus, development of the alternative-scaling product is an inevitable factor. As prospective scaling acids, NaF, NH4HF2, NH4F, and H2SiF6 were discreetly selected and applied on 303F stainless steel.

NaF, NH4HF2, and NH4F showed a highly comparable scaling abilities with HF. This result provides a clue that the selected acids can replace the use of HF in the scaling process. In addition, scanning electron microscopy (SEM) analysis was adopted for the verification of scaled surface of the stainless steel.

Graphene is a Nobel Prize-winning two-dimensional carbon allotrope with compelling properties. Active research is being performed to develop pioneering application using this interesting material. However, graphene is typically produced with heterogeneous size and thickness distributions, which can affect the properties of this nanomaterial. Thus, a reliable method to assess the morphology of graphene materials is of immediate interest for industrial application of graphene.

In collaboration with Research Institute of Industrial Science and Technology (RIST), we developed a thorough protocol to analyze the morphology of graphene using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The development of the protocol is expected to provide a standard for evaluating the quality of graphene materials and contribute to the production graphene materials with reproducible performance.

Polymers have become one of the most important materials in modern society. Due to their importance, significant advances were made for their analysis. However, the analysis of polymeric mixture is still difficult. Reliable analysis method for polymeric mixture would be a key technology for quality control and polymeric product development. By combining infrared (IR) spectroscopy, mass spectrometry (MS), and gel permeation chromatography (GPC), we have successfully analyzed the components in various polymeric mixtures.
