Mars, the most Earth-like of the planets, has motivated scientists to search for life there. Presently, plans are in the works for landing humans on the Red planet between 2025 and the 2030s. Young students of today may have an opportunity to travel to Mars and /or serve as future astronauts. Therefore, it is important to provide them with enjoyable and rewarding learning experiences about space travel and the planet Mars. This paper describes successful STEM activities that use innovative e-learning to simulate components of real Mars missions.

N,N-diethyl-N-(2-methancryloylethy)-N-methylammonium bis(trifluoromethylsulfonyl) imide polymer (DEMM-TFSI) brush coated specimens (substrate: glasses) and a liquid ion type of polymer brush coating were investigated for their antifouling effect on biofilms. Biofilms were produced by two kinds of bacteria, E. coli and S. epidermidis. They were formed on specimens immersed into wells (of 12-well plates) that were filled with culture liquids and bacteria. The biofilm formation was observed. Also, brush coated specimens and glass substrates were investigated in the same way. DEMM polymer brush coated specimens formed more biofilm than PMMA (polymethyl methacrylate) polymer brush coated specimens and glass substrates. A greater amount of polarized components of biofilms was also observed for DEMM polymer brush coated specimens. The polar characteristics could be attributed to the attraction capability of bacteria and biofilms on DEMM polymer brush coated specimens. When considering the ease of removing biofilms by washing it with water, the ionic liquid type polymer brush (coated specimens) could be used for antifouling applications. If an initial antifouling application is needed, then the polar characteristics could be adjusted (design of the components and concentrations of ionic liquids, etc.) to solve the problem.

This chapter focuses on E‐coli and examines the biofilm formation behavior on surfaces of titanium alloys using the own unique laboratory biofilm reactors. The evaluation of biofilms was carried out by the combination of optical microscope, Raman spectroscopy, and staining by crystal violet in an experiment. Specimens were placed on the observation stage and photos were taken at many different places around the focal point. Then all of the photos were integrated into a 2D map. Typical surface profiles show bumpy surfaces in micrometer orders or more. Concave‐convex profiles of biofilms are shown in terms of color differences. The red color sections correspond to convex portions and blue colors to concave ones for the apparatus used in the experiment. The surface organic matters, corresponding to the organic constituents (EPS), were analyzed and representative peaks for polysaccharides, proteins, lipids, nucleic acids were obtained.

This chapter focuses on the correlation between applied elastic waves and biofilm formation in a circulating type of laboratory biofilm reactor (LBR). Several metallic specimens were inserted into the LBR and elastic waves were applied to them for a certain period of time in an experiment. The other method of measurement was the staining test using crystal violet agents. This chemical can stain bacteria themselves and also EPS. Specimens were immersed in 0.1% crystal violet solutions for 30 minutes. The intermediate colors refer to heights between the highest and lowest and they change according to the height. The slight sea‐island patterns were observed when the ultrasonic waves were applied. Since the optical microscopic observation was a local measurement, the results suggest that biofilm still formed at some places on the aluminum surface. Chromium plated specimens were not affected by sonic waves. The extent of violet colors did not change in the case with and without sonic waves. The same tendency was also observed for the glass specimens.

A virtual workshop for creative teaching was successfully carried out in Second Life (SL) with elementary school teachers (teachers of young children). Creative teaching is important for engaging and motivating students (of all ages) to pursue academic studies, especially in the areas of STEM (science, technology, engineering, mathematics). Countries need a supply of qualified STEM graduates to compete globally, creatively solve challenging problems, and provide the scientists, engineers, etc. of the future. The participants had no previous experience with SL, so they enjoyed the workshop very much and liked the creative setting (virtual classroom) and opportunity to make and operate their own avatars. This paper describes five creative teaching techniques, the teachers’ brainstorming session, and lesson ideas for turning students onto learning.

A type of polymer brush, made from an ionic liquid, was prepared and used to investigate the behavior and tendency of biofilm formation. The polymer brush specimens were immersed into the wells of microtiter plates filled with culture liquids containing bacteria. Two different combinations of bacteria and liquid cultures were used for this experiment. One was LB liquid medium with E-coli and the other was Heart Infusion liquid medium with S.epidermidis. After the specimens were immersed for a certain amount of time, they were removed from the test wells and evaluated for biofilm formation. The evaluation methods used were Raman Spectroscopy and crystal violet staining. Polymer brush specimens generally showed biofilm formations for specimens tested in both bacterial cases. However, both of these biofilms could be removed, when the specimens were immersed in water for a couple of hours. Probably the use of special polymer brushes will be valuable in the future, for controlling biofilm and related contaminants on a variety of materials and components.

Graphene is an advanced material. We confirmed in our previous paper that graphene is very sensitive to biofilm formation. Therefore, it may be utilized as a sensor for biofilm formation in the future. In this experiment, we used graphite and multi-layer graphene, which we obtained by repeating an exfoliation method. The biofilm formation was evaluated by crystal violet staining, Raman spectroscopy, and chronoamperometry in dilute sulfuric acid. The final technique was an adventurous trial. However, the method provided us with reasonable data, as compared with the results of the other two conventional methods.

The formation of biofilm on graphene materials was investigated in this study. Two kinds of laboratory biofilm reactors were used to produce biofilms artificially on glass specimens (on the laboratory scale). One of them was a loop-type and the biofilms were measured by Raman spectroscopy. The other one was the static immersion test in a culture containing bacteria. The biofilm formation was evaluated by using crystal violet. We expected that the graphene would have a strong resistance against biofilm formation. However, on the contrary, graphene tended to become more sensitive to biofilm formation when the portion of graphene increased. When we come to think about the future application for graphene, it should not be used for biomaterials, but as sensor for infectious diseases.

Biofilm formation was carried out using low concentrations of ionic liquid (IL) to investigate the potential control of biofilm formation with IL. A 2000ml reservoir was filled with tap water with/without a low concentration of ionic liquid in aqueous solution. The apparatus (Laboratory Biofilm Reactor: LBR) was a loop type Laboratory Biofilm Reactor (LBR) composed of an acrylic pump and a bottom tank. A pump circulated the water in the loop system of the laboratory biofilm reactor (LBR). The glass specimens were immersed in the LBR with/without a low concentration of ionic liquid in aqueous solution for 2 or 7days. They were observed and evaluated by using Crystal Violet, a 3D optical microscope and a Raman spectrometer to determine their biofilm behavior. The results were discussed from the viewpoint of a cooling pipe system simulation. We found out and confirmed that the formation of biofilm was controlled when a low concentration of aqueous solution of ionic liquids was circulated.

A project about renewable energy was successfully carried out in Second Life (SL) by a team of Japanese students with a U.S. instructor who used English to communicate. This was a challenging task, especially since the students’ first language is Japanese. To improve the learning environment, a teaching assistant was available to translate information from English to Japanese when necessary. This paper describes the successful STEM (science, technology, engineering, mathematics) activity in SL where the Japanese students designed and built a special airplane for wind energy. It also mentions other contributions of our work, such as the incorporation of an Engineering Design Process into the lesson and the advantages we found by carrying out the renewable energy project in a virtual reality environment.

Biofilms consist of not only bacteria but also extracellular polymer substrates (EPS). They are groups of microorganisms that adhere to each other on a surface, especially as a result of exposure to water and bacteria. They can pose health risks to humans as they grow in hospital settings that include medical supplies and devices. In a previous study, the researchers discovered that bacteria/biofilm grew well on wetted external latex, male catheters. These results concerned the investigators and encouraged them to find ways for prohibiting the growth of bacteria/biofilm on the male catheters (which are made of natural rubber). They carried out a new study to assess the influence of metals and voltage for the growth of bacteria on these latex samples. For this purpose, a unique Rotation Disk Reactor was used to accelerate biofilm formation on external male catheter samples. This setup included a dip tank containing water and a rotating wheel with the attached latex samples (some of which had single electrodes while others had paired electrodes with applied voltage). The process allowed the samples to become wetted and also exposed them to microorganisms in the ambient air during each revolution of the wheel. The results (as viewed from SEM images) showed that when compared to the control sample, the presence of metals (brass, stainless steel, and silver) was generally effective in preventing bacterial growth. Also the use of voltage (9.5 volt battery) essentially eliminated the appearance of rod shaped bacteria in some of the samples. It can be concluded that the presence of metals significantly reduced bacterial growth on latex and the application of voltage was able to essentially eliminate bacteria, providing appropriate electrode combinations were used.

Corrosion is basically the oxidation of metals, where electrons are transferred between oxidant and reductant. Therefore, corrosion is generally composed of redox reactions and should be analyzed from the viewpoint of electrochemistry. In this chapter, we describe the basic concept of electrochemistry and how various corrosion aspects can be explained by this discipline. We focus particularly on the equilibrium side because it could suggest possibilities that might be useful for corrosion prediction. The close relationship between redox reactions and corrosion are explained and stressed qualitatively and quantitatively.

As described in detail already, environmentally friendly surface finishing processes are available by substituting the original process or plating itself with something less harmful. As for the process changes, we described the details and gave examples in chapter “Process Changes”. In that chapter, we mainly mentioned physical vapor deposition (PVD). On the other hand, we focused on the substitution of plating materials from aqueous solutions. As concrete examples, we talked about some aqueous processes for the substitution of hexavalent chromium plating. This chapter mainly describes alloy plating processes, trivalent chromium processes and composite plating.

Treatments to the surfaces of metals as well as other items are very important in most industries. They are used to enhance substrates’ appearances and to improve their functions such as reflectivity, hardness, and corrosion resistance. This chapter describes some surface finishing processes. It discusses the change from metals to nonmetal substrates. Also the topics of resins, composites, and plastics are introduced.

As described in detail already, environmental friendliness is needed for sustainable development. There are two basic ways to make the surface finishing process more environmentally friendly. One of them is the substitution of hazardous materials with harmless substances. The other one is the utilization of a closed system for surface finishing/coating. From the viewpoint, physical vapor deposition (PVD) and chemical vapor deposition (CVD) seem to be the most favorable processes, since both have already been established. In this chapter, we describe both processes and discuss the effectiveness and possibility of changes from the conventional plating process to a dry process.

After World War Two (WW2), Japan sought for industrial development and entered a high-growth period with the growth of baby boomers.
