World Premier International Research Center Initiative (WPI) Executive Summary (For Final Evaluation) World Premier International Research Center Initiative (WPI) Executive Summary (for Final Evaluation) Host Institution National Institute for Materials Science (NIMS) Host Institution Head Kazuhito Hashimoto International Center for Materials Nanoarchitectonics Research Center Center Director Masakazu Aono (MANA) About filling out this form: This summary is to be based on the Center’s Progress Report and Progress Plan, with reference to the following items, prepare the summary within a space of up to 6 pages. A. Progress Report of the WPI Center I. Summary In the eight and a half years since it was established, MANA has grown to become one of the world’s top research centers in the relevant fields and produced remarkable results in fields ranging from fundamental research to practical applications. MANA’s excellence can be found represented in several key indicators. Among these, A) 118 of MANA’s papers are now among the top 1% most cited papers in the world; B) MANA has achieved an extremely high score of 2.42 for Elsevier’s Field Weighted Citation Impact (FWCI), a new index created to “fairly compare the quality of papers published by research institutions that work in different fields” (both A and B refer to statistics for papers published between 2008 and 2015); and C) MANA’s papers are printed in journals with an extremely high average Impact Factor (IF) of 6.16 (2015). MANA’s scores for these indicators are superior to those of many world-class research institutions. MANA has a unique characteristic compared to other materials science laboratories in the world. Its operations are based on a new concept: a new nanotechnology paradigm called “nanoarchitectonics.” This unique concept is the key to MANA’s achievement of its striking research results. In eight and a half years, MANA has accomplished much outstanding research. Some representative examples include a) nanosheet technology and its applications, b) atomic switches and related devices, c) various unimolecular devices, d) highly efficient photocatalysts, e) highly sensitive / parallel molecular sensors (MSS odor sensors, etc.), f) diagnosis and treatment using nanoarchitectonics, g) transmission electron microscopes that can observe electrical, mechanical, and optical properties under high-resolution structural observation, and h) multiple-probe scanning probe microscopes that can measure electrical conductivity at the nanoscopic scale. Over 50% of the researchers at MANA are non-Japanese, making it the most internationalized research center in Japan. MANA has succeeded in creating an almost perfect environment in that it expeditiously provides administrative and technical support to all MANA researchers, including non-Japanese researchers. MANA can give back to NIMS the obtained knowhow and experience of management an international research center. For example, English-language support for non-Japanese researchers within NIMS as a whole has been greatly improved. In addition to the WPI program’s four pillars, MANA has one extra pillar of its own: the cultivation of young researchers. MANA’s systems of independent researchers (approx. 20% of permanent researchers), who pursue their own research topics without belonging to any specific group, and ICYS researchers (approx. 20% of post-doctoral scholars) have attained remarkable achievements. Since FY 2012, MANA has been defined as one of NIMS’s three research arms, and it is becoming a permanent presence within the NIMS research organization. NIMS also provides salaries for approximately 90 permanent staff and otherwise provides comprehensive support for MANA in many ways, something that will continue on into the future. II. Items 1. Overall Image of our Center <Vision and background> When MANA was launched eight and a half years ago, nanotechnology (and the nanoscience on which it is based) was in a state of rapid development and becoming an essential pillar of materials science. It was in this context that we designed MANA with the intention of cultivating a world-class research center that would effectively employ nanotechnology to make powerful advances in the research and development of new materials. We were strongly aware of the common mistake of considering nanotechnology to be a continuation of conventional NIMS - 1 MANA microtechnology, and moreover that nanotechnology’s true power cannot be effectively harnessed unless nanotechnology is properly recognized as being qualitatively different from microtechnology. Thus, we established MANA’s guiding vision as “Pioneering a new paradigm of nanotechnology to create a research hub for the best new materials development in the world.” In order to concisely express this new technology paradigm, we coined the concept of nanoarchitectonics. This concept is described in more detail in the “Progress Report,” but it serves to distinguish MANA’s research from other nanotechnology research institutions. We at MANA are pleased to see that the nanoarchitectonics concept has begun to gain approval throughout the world. <MANA today> MANA was founded on research in four fields—Nano-Materials, Nano-System, Nano-Power, and Nano-Life—but in FY 2016 it established a new field, Nano-Theory. At present, MANA houses 25 principal investigators, 2 associate principal investigators, 75 permanent researchers, 72 post-doctoral researchers, and 36 students who conduct research in 5 fields. These researchers are supported by 29 administrative and technical staff. The present state of MANA can be summarized by the following five points: ★ Achieved world-class research activities ★ True international center with over half of researchers being of foreign nationality ★ Active fusion research that combines nanotechnology and other fields ★ Steadily fulfilling its responsibility to reform its host institution, NIMS ★ Training excellent young researchers who work throughout the world <Future outlook> Building on eight and a half years of experience and confidence, MANA pursues interdisciplinary, fusion research centered around the fusion of “theoretical research and experimental research,” and the fusion of “nanotechnology (nanoarchitectonics) and life science.” Our final objective is to develop through innovative technologies new materials that will shake up the world. There is tremendous potential for this goal to be realized. 2. Research Activities <Remarkable research accomplishments> As explained above, MANA’s research is conducted in five fields (Nano-Materials, Nano-System, Nano-Power, Nano-Life, and Nano-Theory.) Below are the main accomplishments of each field of research. A) Inventing nanosheet-based new materials: MANA developed and implemented creative nanosheet methods used to create a variety of new materials with novel and useful properties. The next step is to use these methods to create metamaterials and new superconductors. B) Development of atomic switches and related devices/systems: The atomic switch operated by a completely different principle than traditional semiconductor devices. MANA invented the atomic switch and moved it toward practical application, where it brought innovation to things like AI and IoT. It was also discovered that atomic switches display functionality similar to synapses in the brain, and hence the next step is to create neutral network circuits made out of atomic switches. C) Best high-efficiency artificial photosynthesis in the world: As an example of this, MANA has succeeded in achieving the artificial photosynthesis of methane. The next step is to use a variety of nanoarchitectonic systems to dramatically improve the efficiency of artificial photosynthesis. D) High-sensitivity / parallel molecular sensors (membrane-type surface stress sensor (MSS)): MANA developed a molecular sensor that is a hundred times more sensitive than traditional molecular sensors, capable of distinguishing between healthy individuals and cancer patients by analyzing their exhaled breath. MANA is currently researching such applications. E) Development of a revolutionary method of nanoscale measurement: MANA developed a transmission electron microscopy (TEM) that can measure electrical, mechanical, and optical properties in high resolution. MANA also developed multiple-probe (2/3/4 probes) scanning tunneling microscope (STM), atomic force microscope (AFM), and Kelvin probe force microscope that can measure electrical conductivity at the nanoscopic scale. <MANA’s three Grand Challenge research topics> MANA has posted three Grand Challenge research topics: NIMS - 2 MANA ★ Artificial brains based on nanoarchitectonics ★ Room-temperature superconductivity ★ Practical artificial photosynthesis These are long-term research targets, but interesting results are already being achieved. Themes 1 and 3 were touched upon lightly in sections B and C on the previous page. Theme 2 has seen achievement in attempts to create superconductivity by introducing electrons and holes into insulators and semiconductors using field effects. In these attempts, researchers succeeded in metalizing diamond. Separately, it has been theorized that when heavy atoms such as gold are formed into a two-dimensional buckled honeycomb lattice and an electric field is applied perpendicularly, current will flow along its edge with zero resistance, even at high temperatures up to 600 K. Experiments are underway in an attempt to verify this theory. <Applications of research achievements> Most of MANA’s fundamental research has led to research into applications conducted in cooperation with a variety of companies

Although it would be impossible to predict all the technical innovations that nano research will offer, it’s already clear that nanoscience will be a major driver of the economy of the future. However, characterizing tomorrow’s nanoscale components and materials will be far from trivial because many of their electrical properties lie at the very edge of the measurement envelope. To unravel tiny mysteries and turn nanoscale materials and devices into commercial products, researchers must have tools with the flexibility to handle a variety of electrical measurements, including current vs. voltage (I-V) characterization, resistance, resistivity and conductivity, differential conductance, transport, and optical spectrum and energy. They must also gain an in-depth understanding of the principles and pitfalls associated with low-level electrical measurements.

Fernando, Ph.D. COMMITTEE MEMBER: Shanju Zhang, Ph.D. COMMITTEE MEMBER: Chad Immoos, Ph.D. iii ABSTRACT Controlling Nanoparticle Dispersions for Nanoscopic Self-Assembly Nathan Stephen Starkweather Nanotechnology is the manipulation of matter and devices on the nanometer scale. Below the critical dimension length of 100nm, materials begin to display vastly different properties than their macro- or micro- scale counterparts. The exotic properties of nanomaterials may trigger the start of a new technological revolution, similar to the electronics revolution of the late 20th century. Current applications of nanotechnology primarily make use of nanoparticles in bulk, often being made into composites or mixtures. While these materials have fantastic properties, organization of nano and microstructures of nanoparticles may allow the development of novel devices with many unique properties. By analogy, bulk copper may be used to form the alloys brass or bronze, which are useful materials, and have been used for thousands of years. Yet, organized arrays of copper allowed the development of printed circuit boards, a technology far more advanced than the mere use of copper as a bulk material. In the same way, organized assemblies of nanoparticles may offer technological possibilities far beyond our current understanding.

Resulting 3D models are based on few 2D microscopy scans and the latest knowledge about the biological entity represented as a set of geometric relationships. Our new technique is based on statistical and rule-based modeling approaches that are rapid to author, fast to construct, and easy to revise. From a few 2D microscopy scans, we learn statistical properties of various structural aspects, such as the outer membrane shape, spatial properties and distribution characteristics of the macromolecular elements on the membrane. This information is utilized in 3D model construction. Once all imaging evidence is incorporated in the model, additional information can be incorporated by interactively defining rules that spatially characterize the rest of the biological entity, such as mutual interactions among macromolecules, their distances and orientations to other structures. These rules are defined through an intuitive 3D interactive visualization and modeling feedback loop.

  • The Value of Public Service Media
    The Value of Public Service Media T he worth of public service media is under increasing scrutiny in the 21st century as governments consider whether the institution is a good investment and a fair player in media markets.

The mutual information of thermodynamic coupling is incorporated into the generalized fluctuation theorem by using information theory and nonequilibrium thermodynamics. Thermodynamically coupled dissipative structures in living systems are capable of degrading more energy, and processing complex information through developmental and environmental constraints. The generalized fluctuation theorem can quantify the hysteresis observed in the amount of the irreversible work in nonequilibrium regimes in the presence of information and thermodynamic coupling. Keywords: information theory; biological systems; fluctuation theorem; thermodynamic coupling 1. Introduction Definition and quantification of information have created broad discussions; particularly, “information theory” in living systems is an evolving field [1–14]. Evolution is an axiomatic consequence of organismic information obeying the second law of thermodynamics; as entropy increases, the information within a biological system becomes more complex and diversifies at bifurcation points [15–18]. Behavior of living systems is decomposable into functional modes and the ensemble of modes at an agent’s disposal constitutes functional repertoire. The modes may be subjected to operational signals and a mechanism that sequentially selects a mode so that it controls the functional dynamics [18,19].

More and more sophisticated designed structures and surface topologies are being developed to basically mimic the extracellular matrix of native tissues such as cartilage and bone. Here we give an overview of the progress made in osteochondral lesion repair, with nano-engineered scaffolds comprising building blocks such as nanoparticles, nanotubes, layer-by-layer nano-assemblies, molecular self-assembly, nanopatterned surfaces…. This nano-engineering technology is coupled with bio-functionalization, by the use of adhesion peptides, growth factors, or deoxyribonucleic acid, to drive cell adhesion, proliferation and behavior towards tissue regeneration. In osteochondral regeneration, the challenge is the simultaneous development of chondrocytes and cartilage extracellular matrix on the one side and a well vascularized bone tissue with osteoblasts on the other side.
