The University

The boundaries between the present performance of materials and the requirements of device designers have for centuries been moving forward. The steps taken to draw these two together are sometimes large; more often they are small. As they occur, we find materials that are stronger, have larger magnetic moments, have higher electron mobilities, etc. Each time the property profile improves, understanding of the physical and chemical properties advances, and new engineering devices based on the improved profile are invented and developed.The purpose of the Center for Advanced Materials (CAM) at the Lawrence Berkeley Laboratory (LBL) is to enhance the inter-play between advances in the property profiles of materials and advances in the chemical and physical understanding of them. For this purpose, the location of CAM can be described as ideal. The proximity of this national laboratory to the campus of the University of California at Berkeley provides an unusually rich intellectual setting for the Center. It also provides unique opportunities for the University students and faculty who conduct materials-related research. Indeed, the arrangement should be a model for similar organizations, and it represents a solid method for strengthening materials science and technology throughout the nation.National policy in critical materials has given the national laboratories—including LBL—strong direction and incentive to collaborate with industry and the research universities. This incentive led to the establishment of CAM in order to build on the symbiosis between LBL and the University of California at Berkeley. It strives to extend this symbiosis by bringing industry into the ongoing educational process and by making its special facilities more readily available to industrial researchers.

Materials Science represents the natural convergence of hard scientific disciplines such as Physics Mathematics and Chemistry whom synergic contribution to its definition and evolution is at the basis of huge technologic development observed during the last few decades. The wide variety of materials under investigation by this discipline is both strategic for the economy of a Nation as well as a fundamental aspect of everyday life. Among the most relevant ones so far proposed, many advanced materials are organic-based or, in other words, constituted by molecules or organic polymers, not only for their application potential, low costs and preparation flexibility but also for their processability and limited environmental impact.

The Materials Research Center at Northwestern University is an interdisciplinary center that supports theoretical and applied research on experimental advanced materials. Conceived during the post-Sputnik era, it is now in its 26th year.The Center, housed in the university's Technological Institute, was one of the first three centers funded at selected universities by the federal government in 1960. The federal government, through the National Science Foundation, now supplies $2.4 million annually toward the Center's budget, and Northwestern University supplements this amount. Approximately one third of the money is used for a central pool of essential equipment, and the other two thirds is granted to professors for direct support of their research. Large amounts of time on supercomputers are also awarded to the Materials Research Center from the National Science Foundation and other sources.The Center's role enables it to provide partial support for Northwestern University faculty working at the frontiers of materials research and to purchase expensive, sophisticated equipment. All members of the Center are Northwestern University investigators in the departments of materials science and engineering, chemical engineering, electrical engineering, chemistry, or physics. The Materials Research Center is a major agent in fostering cross-departmental research efforts, thereby assuring that materials research at Northwestern University includes carefully chosen groups of faculty in physics, chemistry, and various engineering departments.

The use of manmade materials progressed rather slowly until the science and technology of metals, refractories, and glass burst forth in the mid-1800s and continued its infancy through the first decades of the 20th century. In fact, much of the scientific wherewithal in industrial nations focused on the development of manmade materials from the standpoint of properties and fabrication processes. From the discipline of metal physics, which emerged in the 1930s, and from the scientific activities in ceramics, polymers, and electronic materials that blossomed in the 1940s and 1950s, a science and engineering base was established, enabling advanced materials and components to be fabricated, often for specific end-user applications. The molecular engineering of crystals, for example, has its roots in von Hippel's studies of dielectric materials at the Massachusetts Institute of Technology, which began in the 1930s. In this time frame, society, which had primarily used such materials as wood, gypsum, clay, copper, zinc, lead, and iron, turned to a broader set of materials to meet new uses. These new applications required an understanding not only of the composition of matter, but of novel and difficult processes as well. Research specialties broadened.From the late 1950s to the present, the knowledge base for materials and components has exploded. In this period, the scientific and technological field of endeavor—materials science and engineering (MS&E) — evolved from a collection of discrete, disparate arts and crafts with varied amounts of science and practitioners who generally did not stray from their own specialties to a more diffuse field where researchers take a broader approach to materials research and practice.

The preservation of U.S. aeronautical leadership is an economic and military necessity, but it is by no means assured. The rise of Airbus, Ariane, and Embraer has been lightning fast; tomorrow could see the development of Japan's FSC or Israel's Lavi. Our competitors are well organized and often enjoy the support of their governments. Our capabilities are no longer unique; thus our future work is clearly defined for us.The key to continued U.S. preeminence in aerospace is to be found in the further research, development, and application of a group of revolutionary technologies in the areas of propulsion, numerical and symbolic computation, laminar flow modeling, and advanced materials and structures. Exploitation of the emerging technologies in these areas by industry, government, and universities will significantly impact the performance and cost of future aerospace vehicles and systems. Materials science and engineering, particularly the discipline of nondestructive evaluation, will play a major role in making such continued aerospace leadership a reality.From the use of plastic and glass radomes in the first jet engine demonstrators to the composite parts of today's most advanced aircraft, the need to ensure reliable materials has always been critical. Advanced materials and structural concepts offer the opportunity for significant airframe improvements on all types of aircraft. Indeed tomorrow's aerospace structures, such as the National Aerospace Plane, the Space Station, as well as the ATF and SDI-related items will employ a myriad of exotic materials that must be extremely reliable and highly producible.

Multicellular tumor spheroids (MCTs) have been employed in biomedical fields owing to their advantage in designing a three-dimensional (3D) solid tumor model. For controlling multicellular cancer spheroids, mimicking the tumor extracellular matrix (ECM) microenvironment is important to understand cell–cell and cell–matrix interactions. In drug cytotoxicity assessments, MCTs provide better mimicry of conventional solid tumors that can precisely represent anticancer drug candidates’ effects. To generate incubate multicellular spheroids, researchers have developed several 3D multicellular spheroid culture technologies to establish a research background and a platform using tumor modelingvia advanced materials science, and biosensing techniques for drug-screening. In application, drug screening was performed in both invasive and non-invasive manners, according to their impact on the spheroids. Here, we review the trend of 3D spheroid culture technology and culture platforms, and their combination with various biosensing techniques for drug screening in the biomedical field.

Underlying Principle

In materials science, there is an intrinsic conflict between high strength and high toughness, which can be resolved for different materials only through the use of innovative design principles. Advanced materials must be highly resistant to both deformation and fracture. We overcome this conflict in man-made polymer fibers and show multifibrillar polyacrylonitrile yarn with a toughness of 137 ± 21 joules per gram in combination with a tensile strength of 1236 ± 40 megapascals. The nearly perfect uniaxial orientation of the fibrils, annealing under tension in the presence of linking molecules, is essential for the yarn’s notable mechanical properties. This underlying principle can be used to create similar strong and tough fibers from other commodity polymers in the future and can be used in a variety of applications in areas such as biomedicine, satellite technology, textiles, aircrafts, and automobiles.
