The 52nd Symposium on Powder Technology organized by Hosokawa Powder Technology Foundation took place at Tokyo Garden Palace, in Japan on Monday, September 3, 2018. It was held by the planning of Council of Powder Technology, Japan and with the sponsorship of Hosokawa Micron Corporation. Over 160 people from the industries and universities attended this symposium. The theme of the symposium this year was “Powder Technology for Synthesis and Application of Power Materials”. There were six lectures including a special one given by the KONA Awardee with questions and answers after each lecture followed by a get-acquainted party for further free discussions.
At the beginning of the symposium, Mr. Yoshio Hosokawa, the president of the Foundation, gave the opening address mentioning that this symposium started in 1968, just 50 years ago and has been continued almost annually since then. Prior to the lectures, the KONA Award presentation ceremony was held and the plaque of KONA Award was handed from the president to Prof. Sotiris E. Pratsinis, who received this Award in the last fiscal year 2017. The KONA Award has been given to the researcher with excellent performance and contributions to the powder and particle science and technology since 1990. It was first started by Hosokawa Micron Corporation and taken over by Hosokawa Foundation after its establishment in 1991. Though it had been presented to Japanese researchers by the Foundation till two years ago, it was opened to worldwide and given to the overseas researcher by the Foundation last year for the first time.
The special lecture given by Prof. Pratsinis focusing on the scalable synthesis of sophisticated nanoparticles with controlled composition, size and morphology by flame spray pyrolysis putting new various high-value products such as single atom catalysts and chemoresistive sensors for breath analysis.
The contents of the symposium are shown below. In the second lecture, the technology of processing and evaluation of nano-carbon based sintered composites using graphene, which shows unique functional properties such as enhanced electrical conductivity, thermoelectric performance and improved mechanical properties.
The following lecture 3 was concerning the white LED application of sialon phosphors used as power luminescent materials and besides forthcoming phosphors applicable for high color rendering lighting or super high vision TV were summarized. In the lecture 4, it was explained about the innovation of sheeting technology of electrodes for on-board battery used for the automobiles based on the fundamental investigation on the rheological behavior and micro structures of colloidal dispersions with the objective of identifying rheological control guidelines for concentrated slurries.
On the other hand, as a spotlighted organic material was introduced in lecture 5 the cellulose nanofibers (CNFs) having unique properties such as high viscosities at low consistencies, characteristic thixotropy behavior by shear forces, high emulsifying and suspending capability, etc. and applied as thickening agent of the ink of the aqueous ball-point pen with unique rheological properties. In the final lecture, the worldwide trends and basic technology of the environment-friendly powder coating using no solvent were introduced together with the new development of the coating system and the related instruments.
