Ceramics inspired by nature

Bioinspired ceramics featuring remarkable properties and functionalities have been successfully created by combining biological design principles with advanced manufacturing technologies. Using for example design principles encoded in the structure of mollusk shells, colloidal assembly approaches have led to bioinspired ceramics whose stiffness and toughness exceed the limits expected from the constituent brittle building blocks. In this talk, I will present some of the manufacturing technologies that have been historically developed to fabricate biologically-inspired tough structural materials and how such bioinspired architectures have now been used as model systems to better understand the toughening mechanisms responsible for the unique fracture resistance of shells. Experiments and theory have shown that highly aligned inorganic platelets connected by an optimal density of mineral bridges are crucial to enhance the toughness of shell- inspired architectures without compromising their high elastic modulus and strength. Beyond mechanical properties, I will also show how advanced colloidal processing can also be used to create ceramics that self-shape into intricate geometries during sintering, following the design principles of plant seedpods. Exploiting the similarities and differences between bioinspired artificial architectures and biological materials opens exciting opportunities to design and fabricate synthetic ceramics with unprecedented properties and to shed new light into the design strategies that emerged from the evolution of structural materials in Nature.

 

 

Materiomics and emerging manufacturing technologies for sustainable development

Mike Murray
Chief Technology Officer Morgan Advanced Materials United Kingdon

Materiomics is defined as the holistic study of material systems. Materials science in itself is one of the most interdisciplinary subjects within science today and the links between physiochemical material properties and material characteristics and function are of continual focus today, and still drive many research efforts. The focus of materiomics is the interconnectivity of material functionality and behaviour, rather than an independent collection of properties. As we strive for the ultimate performance, it is the fundamental understanding of the mechanisms that exist and ultimately the link between processes, structures, and properties at multiple scales, from nano to macro.

Only through this systematic approach to understanding the building blocks of materials science can we continue to enhance and drive innovation. Innovation and growth opportunities continue at a pace within the advanced ceramics market place and the performance challenges being pushed to the material limits. We will review that while product innovation and differentiation is always important, interconnected operational and supply chain innovations lead to a more productive and profitable manufacturing company. Creating a company culture that focuses on innovating in all aspects of the business process can have a dramatic impact on the chances of success, but also productivity of the entire supply chain.

Why Soft Processing(=Low-Energy Production) of Advanced  Materials is Difficult but Necessary for Sustainable Society?

Modern our society has been developed with various advanced materials. Most of advanced materials, Metallurgical materials, Semiconductors, Ceramic materials and Plastics have been used in wide area of applications like structural, mechanical, chemical, electrical, electronic, optical, photonic, biological, medical, etc. Most of them except for bio-polymers & bio-minerals have never been produced  via biological systems. Thus they have generally been fabricated artificially and/or industrially by so-called high-technology, where  high temperature, high pressure, vacuum, molecule, atom, ion, plasma, etc. have been used for their fabrications, then consumed huge amount of resources and energies thus exhausted  huge amounts of wastes: materials, heats and entropy. To save this tragedy, we must consider water-based industries.
Considering the lowering of  total energy consumption, we have challenged to fabricate those advanced inorganic materials with desired shape/size/location,etc. directly in low energetic routes using aqueous solutions since 1989 when we found a method to fabricate BaTiO3 film on Ti substrate in a Ba(OH)2 solution by Hydrothermal Electrochemical[HEC] method at low temperatures of 60-200 C.  We  proposed in 1995 an innovative concept and technology, “Soft Processing” or “Soft Solution Processing,” which aims low energetic (=environmentally friendly) fabrication of shaped, sized, located, and oriented inorganic materials in/from solutions.  It can be regarded as one of bio-inspired processing, green processing, or eco-processing.  When we have activated/stimulated interfacial reactions locally and/or moved the reaction point dynamically, we can get patterned ceramic films directly in solution without any firing, masking nor etching.   Direct Patterning of CdS, PbS and CaWO4 on papers by Ink-Jet Reaction method. Furthermore, we have succeeded to fabricate BaTiO3 patterns on Ti by a laser beam scanning and carbon patterns on Si by plasma using a needle electrode scanning directly  in solutions.  Successes in TiO2 and CeO2 patterns by Ink-Jet Deposition, where nano-particles are nucleated and grown successively on the surface of substrate thus become dense  even below 300 C will be presented. Nano-structured films will be also talked. .A recent novel subject, Soft Processing for various nano-carbons including Graphene and functionalized Graphene, will be introduced. Where we have succeeded to prepare functionalized Graphene Ink via successive processes under ambient temperature  and pressure conditions.(3-6)

Glasses and glass transition for ceramists

Natural glasses have “always” existed, whereas synthetic glasses were created approximately 6,000 years ago and are now omnipresent - and unreplaceable in many cases - in our daily routine. In this talk, we
will consider some fundamental questions related to the intrinsic nature of glasses, which are not always clear to ceramicists, such as: what is glass? What is the glass transition? Are glasses solids or liquids? Do glasses flow at room temperature? Can all glasses be crystallized? We will show that glasses are unstable and spontaneously start to relax toward the supercooled liquid state at any temperature above absolute zero. Finally, to end the science part of the talk, we present and explain a modern definition for glasses.

To illustrate their realm of applications, we show some novel uses of modern inorganic glasses, such as bioactive glasses, optical fibers, spectacles for colorblind correction, UV and IR-filters and ultra-strong glasses for electronic device displays. We finally show that, after controlled crystallization, specific glasses turn into glass-ceramics -- polycrystalline materials that are related to, but not the same as sintered ceramics. Glass-ceramics exhibit some unusual combinations of properties that make them unique, such as dental applications or transparent, low CTE materials for telescope mirrors and cooktops.

The talk is illustrated using videos about the glass transition phenomenon and some unusual mechanical properties. We finish the speech by asking three questions to the participants: How many vitreous materials have already been made? How many can still be produced? How can new glasses be designed? Optimistically the speech and its contents will be
educative and fun for ceramists, and even perhaps for glass scientists?

*Note: Due to personnal reasons, Dr. Martin Harmer's talk was cancelled.
