Our Analysis & Simulation Center is a critical resource that delivers practical and implementable solutions to real industrial problems, with expertise in state-of-the-art instrumental analysis and theory-oriented computational simulations. We constantly strive to extend the frontiers of the wide range of analytical methodologies we employ, keeping an open mind for innovation, and advancing collaboration with leading researchers around the world.
As the world faces growing challenges related to the environment, energy, and aging populations, Japan will play a leading role in the development of solutions based on advanced materials and efficient production processes. Analytical technology is the key that enables the power of science to be applied for the achievement of sustainability for the future.
One notable example of an Asahi Kasei product that addresses environmental and energy issues is the Hebel™ series of autoclaved aerated concrete panels for exterior walls featuring superior strength, insulation, and extended durability. Although the manufacturing method was established many years earlier, there had not been a clear understanding of the curing process of pulverized silica stone within large industrial-scale autoclaves, especially from the perspective of kinetics. To elucidate the reaction process scientifically, we applied the synchrotron radiation (SR) in-situ measurement technique and successfully observed changes in the crystal phases as the curing process proceeds. The study revealed that several intermediate phases play a decisive role in determining the strength and durability of the product material.
Particular expertise was required to develop a small observation cell suited to in-situ measurement, and to reproduce the phenomena in a real-world industrial process. We apply similar techniques to various proprietary organic and inorganic products.
Optical materials make our life convenient and colorful in many ways. Various optical properties are achieved with fine surface structural patterns or textures whose feature size is smaller than the wavelength of visible light. Materials with such fine surface structures are assembled into large devices up to several meters in scale.
Jointly with Ohio State University, we developed several approaches to simulate optical properties on a real-world scale based on the fine surface structural patterns and intrinsic material properties.
High temperature, high pressure reactions in real-world production processes can be reproduced using a reaction cell we developed in house, casting light on various black-box phenomena occurring in industrial production processes. This technology has been recognized with the Hyogo SPring-8 Award 2011 and with the Advanced Analytical Technology Award 2010 from the Japan Society for Analytical Chemistry.
Scanning electron microscopy observation, theoretical modeling, and optimization techniques are combined to reproduce fluid dynamics phenomena with microporous materials, enabling engineering solutions for novel high-performance filtration systems. This technology has been recognized with the Technology Award 2004 from the Japanese Society for Artificial Organs.
Surface analysis techniques such as STEM, XPS, and SIMS are coupled with first-principle theoretical simulations elucidating the interpretation of spectra profiles and yielding information about the underlying atomistic alignment.
With PFG-NMR techniques, the behavior of ionic species within polymers and membranes is clarified to facilitate the development of various new battery devices.
Our advanced techniques enable the practical observation of structures on the scale of several hundred nm, as well as in-situ observation of structure formation processes.
We jointly developed OCTA, a meso-scale multi-physics simulation system for the modeling and design of materials such as separation membranes, films, and textile fibers. This technology has been recognized with the Technology Award 2002 from the Society of Rheology Japan.
