Polymers are used in a wide range of fields such as food wrapping materials, medicine packing, and industrial materials and products. Properties and functionalities of polymer materials are dependent on various factors, including molecular weight, molecular weight distribution, molecular chemical structures (primary structures), morphology of molecular chains (secondary structures) depending on the spinning angles of chemical bonds, and crystalline or non-crystalline structures of inner-molecules and inter-molecules, as well as spherulite structure aggregates, phase separation structures and orientations (higher-order structures). It is of prime importance to analyze and evaluate the structures and properties of polymers as well as the correlation between these two factors, and to feed these analysis and evaluation results to the development and manufacturing sites for the enhancement of the performance and quality control of polymer materials and polymer products. On the other hand, industry in Japan is supported by functional molecules, which are becoming more advanced and more complicated. This makes it more difficult to characterize such polymers, thereby increasing the importance of multiple analyses that combine a variety of analytical methods. This Polymer note introduces a broad range of instruments used for polymer analysis and their applications.

Solid State Battery Note

Tue, 05 Mar 2024 09:57:55 GMT

Battery cells are essential in modern life as they are extensively used in mobile phones, personal computers, and even in automobiles as the power source in recent years.
The shift to battery vehicles (BEV) is rapidly advancing worldwide in order to achieve carbon neutrality by 2050 which is to “reduce overall greenhouse gas emissions to zero”. The research and development on rechargeable battery cells that can be used repeatedly, are progressing for the use of power source of BEV and larger energy storage system (ESS). To improve both the performance and quality of these battery cells, analyses and evaluations by using various high-performance evaluation instruments are required.
JEOL offers a wide variety of analytical instruments available for morphological observations, surface analyses, structure analyses, and chemical analyses at micro- to nano-scales for the purpose of research, development, and quality improvement.
This Solid-state battery Note has been created with the samples provided by Prof. Atsunori Matsuda, Toyohashi University of Technology (Department of Electrical and Electronic Information Engineering), to provide solutions and reference information for research and development of solid-state batteries evolving from the lithium ion batteries (LIBs).

Instrumental analysis has contributed to the progress of biological science, through the observation of morpohology, the chemical analysis of compounds, the elucidation of amino acid sequences of proteins, etc. Furthermore, this progress has been accelerated by the development of analytical methods, which are used in diverse fields like medical science, agriculture, food and biotechnology, as well as the basic research work like physiology, biochemistry and genetics.

This Bionote presents an overview of the basics, namely principles and features of various instruments, as well as application examples using numerous optional attachments. We hope that the Bionote will assist researchers and engineers who intend to perform analyses in finding and exploring new approaches.

Learning Polymer Materials Analysis from Natural Lacquer (Urushi)

Fri, 10 Jul 2020 19:45:25 GMT

Introduction:

In recent years, polymer materials have become more complex due to increased composition and diversification so that a one-sided analysis is insufficient and multifaceted observations and analyses are required.
In response to this need, JEOL has engaged in applied research under the keyword of "YOKOGUSHI" (multifaceted cross-instrumental) using various instruments organically.
In this Urushi Note, multifaceted analysis methods for polymer materials are illustrated using the examples of natural lacquer (urushi) analysis. The use of TEM, SEM, ESR, NMR, MS, and FT-IR instruments is undertaken.
