As part of the “Turkiye-Italy Joint Webinar series program” initiative sponsored by the American Ceramic Society, Research Director Dr Vincenzo Buscaglia at 2 p.m. on 10/02/2025 will hold a seminar titled “Powders synthesis and particle morphology control: better materials from chemistry.”

Below is the abstract of the seminar:

Powders synthesis and particle morphology control: better materials from chemistry.

The production of innovative ceramic and inorganic materials strongly depends on the availability of good quality powders with specific properties
in terms of stoichiometry, size, shape, particle size distribution, etc.. Among the various powder synthesis methods, solid-state reaction and hydrothermal synthesis are quite popular and largely used at the industrial scale. A chemistry-based approach is an effective strategy to produce particles with controlled morphology with both routes by designing specific precursors and reaction paths. In this lecture three different chemical strategies as applied to perovskite compounds, in particular BaTiO3 and SrTiO3, as model systems will be presented. Namely: (i) Topochemical reactions, (ii) Organic modifiers and (iii) Core-shell particles. Topochemical reactions allow for a conscious manipulation of different precursors and their transformation in the final compound retaining crystallographic order and morphology. The addition of organic molecules/polymers and/or the use of gel precursors in hydrothermal processes not only affect morphology but also enables non-classical crystallization mechanisms with formation of mesocrystals and other organized structures. The synthesis of core-shell particles offers an important tool for the fabrication of non-conventional precursors and composite materials with unique functional properties.

Dr. Buscaglia’s Seminar will be followed by Dr.Ender Suvaci (from Eskişehir Technical University, Türkiye) seminar titled “The lab-to-market story of MicNo® particles”, which abstract it’s below.

The lab-to-market story of MicNo® particles

Ceramic particles play a critical role in determining the properties and performance of the devices/systems in which they are used as building blocks. Accordingly, the performance of the materials can be enhanced by tailoring particle characteristics such as size, shape, surface area and porosity to meet the needs of the application. This presentation will discuss the story of a designed particle technology, called as MicNo® -ZnO particles, from the laboratory to the global cosmetic market where the MicNo particles offer significant advantages over both micron and nano-sized ZnO particles as UV filters. The development of this particle technology from laboratory to market is an example of the synergy between scientific discovery and entrepreneurial vision. This presentation will reflect the key stages of this journey, including initial identification of need, conceptualization and experimentation, rigorous validation, and optimization, navigating the regulatory landscape and forging key industry partnerships. The presentation will explore the challenges encountered, the solutions developed and the significant impact of this technology across multiple sectors besides cosmetics. This story will not only demonstrate the transformative potential of innovative particle technology, but also provide valuable insights into the critical elements of successful commercialization, highlighting the importance of interdisciplinary collaboration and strategic foresight.
