The research team also included collaborators from Assoc. Prof. Engin Durgun\u2019s (UNAM) and Asst. Prof. Zafer Say (TOBB University) and research groups.<\/p>\n<p>Most of the industrially produced chemicals used in medicine, pharmacy, energy storage\/conversion, automotive, electronics, paints, food, textile, etc. are obtained using special chemicals called \u201ccatalysts\u201d enabling faster, cheaper, safer, and environmentally friendly synthesis of consumer products in large scales. The cost of global catalyst production by the chemical industry approaches $50 billion\/year, while the economic value of the products generated by these catalysts is estimated to exceed $ 0.2 Trillion\/year, globally. Hence, a fundamental understanding of catalyst chemistry is of paramount industrial significance.<\/p>\n<p>Catalysts are often comprised of tiny particles with diameters of a few nanometers. Thus, catalyst design, synthesis, and characterization demand a very high accuracy at the nanometer scale. While there exist several conventional spectroscopic\/microscopic techniques providing nanometer-scale analysis of catalysts, there is typically a trade-off between spatial resolution and chemical information. In other words, many techniques enabling the detection of very small catalyst particles, typically fail to provide detailed chemical knowledge of such systems. Furthermore, it was theoretically established by Ernst K. Abbe in 1873 that the spatial resolution of such analytical techniques is limited to half of the wavelength of the probe particles used in detection (e.g., photons, electrons, ions).<\/p>\n<p>In their recent work, \u00d6zensoy research group and their research collaborators demonstrated for the first time that a novel spectroscopic technique called scattering-type near field optical microscopy-based nano-Infrared (s-SNOM Nano-IR) spectroscopy can be utilized to beat the Abbe\u2019s diffraction limit to investigate sulfur poisoning of catalytic particles at the nanometer scale under technically relevant experimental conditions. Prof. \u00d6zensoy points out that \u201cthe current work also may pave the way for the future high-resolution\/high chemical definition studies on many other nano-systems relevant for electronics, battery technologies, sensors, and nano-biotechnology\u201d.\u00a0 Along these lines, a news article on Prof. \u00d6zensoy\u2019s paper was also just published in AZO Materials (<a href=\"https:\/\/www.azom.com\/article.aspx?ArticleID=21662\">https:\/\/www.azom.com\/article.aspx?ArticleID=21662<\/a>), a globally known online publication for the Materials Science community.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A collaborative research team led by Professor Emrah \u00d6zensoy, Bilkent University Chemistry Department Head, Faculty Member, and UNAM associate recently published a paper entitled \u201cUnravelling Molecular Fingerprints of Catalytic Sulfur [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":6680,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[56],"tags":[],"class_list":["post-6679","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-2022"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.13 -
