Jacek Jagiello, Ph. D,

Senior Scientist,

Dr. Jacek Jagiello received his M.S. degree in chemistry from Jagiellonian University, in Krakow, Poland, with a specialty in Quantum Chemistry. He received his Doctorate in Chemistry at M. Curie-Sklodowska University, Lublin, Poland in 1984, studying the thermodynamics of physical adsorption on heterogeneous surfaces, under the supervision of Prof. W. Rudzinski.

Dr. Jagiello has authored and co-authored more than 90 scientific publications, including two book chapters and more than 40 lectures presented at international conferences. He has also co-authored four U.S. patents.

In 2008, Dr. Jagiello joined Micromeritics, where he is involved in the development of methods for interpretation and modeling of adsorption measurements. His research interests are focused on adsorption properties of non-porous and porous materials – with special interest in the advancement of the understanding and characterization of activated carbons.

He began his study of the theory of physical adsorption on heterogeneous surfaces as an Assistant Professor and Research Assistant at the University of Science and Technology (AGH) in Krakow. As a Postdoctoral Research Associate at the Centre National de la Recherché Scientifique (CNRS) in Mulhouse, France, he studied Inverse Gas Chromatography, participating in a group under the direction of Dr. Papirer. Later, holding a second postdoctoral position with Prof. Schwarz at Syracuse University, Syracuse, New York, he worked on hydrogen and methane storage on activated carbons.

In 1996, Dr. Jagiello moved from academic to industrial research when he joined the Carbon Research Group at the Charleston Research Center of Westvaco Corporation in Charleston, South Carolina . His research projects were primarily related to the development of methods for characterization of activated carbons and to the pore structure-based modeling of carbon performance for specific applications. Later, collaborating with several international scientific groups, Dr. Jagiello contributed to research in the area of adsorption of various gases, including hydrogen, on carbon nanotubes, metal organic frameworks, and other porous materials, while he worked at Quantachrome, Boynton Beach, Florida. One year before joining Micromeritics he returned briefly to academia as a visiting scientist at The University of Kentucky Center for Applied Energy Research, where he conducted research projects in the areas of energy storage in carbon double layer capacitors and the capture of CO2 from the flue gas of coal fired power plants.

Simon Yunes, Ph.D.,

Senior Application Scientist

Dr. Yunes received his B.S. degree in Chemistry from the Central University of Venezuela. He received both his M.S. and Ph.D. degrees in Physical Chemistry from Catholic University of Louvain, Louvain-La-Neuve, Belgium, with “La Plus Grande Distinction,” the highest honor to be granted by the University. His Ph.D. thesis was carried out under the supervision of Prof. Bernard Delmon, worldwide authority in the field of catalysis.

Dr. Yunes is recognized worldwide for his contribution to the field of adsorption and the application of adsorption techniques to the characterization of solids, particularly catalysts. During his studies in Belgium, Dr. Yunes was able to synthesize hydrotreating (HDT) catalysts from natural laterite and bauxite (naturally abundant in Venezuela) to efficiently remove impurities from Venezuelan heavy crude oil and lengthen the life of the classical catalysts used in such a process. His knowledge and interest in adsorption began at that time. All the synthesized catalysts were characterized using adsorption techniques for both physical adsorption, to study structure, and chemisorption, to determine the active metal dispersion of the catalysts. Dr. Yunes joined Micromeritics in May 1984, where he held the position of Senior Application Scientist, conducting experiments on adsorption, assisting the development of new products and writing application notes. His primary function at Micromeritics was to support customers worldwide with their applications, and to find or assist in developing new technologies to meet the needs of customers. From 1992 to 1996 Dr. Yunes managed a Micromeritics laboratory at the Venezuelan Research Institute (IVIC) in Caracas, Venezuela. This position was dedicated to assisting under-graduate and post-graduate students in characterizing their catalysts and to support their research for attaining their degrees. From 2004 to 2009 Dr. Yunes supervised the Catalyst Characterization Laboratory at the Venezuelan Petroleum Institute INTEVEP, serving all national refineries belonging to PDVSA, the Venezuelan National Oil Company. In September 2009, Dr. Yunes returned to the Micromeritics headquarters in Norcross, Ga, where his primary responsibility is the support of customers worldwide in their application of Micromeritics technologies. Dr. Yunes has given more than 150 presentations and seminars around the world in many languages. He speaks six languages, and he is a co-author of the Micromeritics book Analytical Methods in Fine Particle Technology.

Anthony W. Thornton, B.S., M.S.,

Senior Product Scientist Director, Product Integrity and Performance

Anthony W. Thornton received both his B.S. degree in Chemistry (cum laude) and his M.S. degree in Analytical Chemistry from Emory University in Atlanta, in 1980.

Tony’s research at Emory involved liquid chromatography, specifically the use of ion-pair chromatography and isocratic separation of catecholamines and metabolites. His work supported early research into potential treatment of Parkinson’s disease between Emory and the Veterans Administration hospital in Atlanta.

By 1983, Tony’s work with liquid chromatography evolved into the study of particle sizing using liquid chromatography, specifically using a technique known as Hydrodynamic Chromatography. His work involved the packing of columns where separation occurs and the co-development of Micromeritics’ first use of the Non-negative Least Squares deconvolution method, later used with Laser Light Scattering and Non-Local Density Functional Theory (NLDFT).

As Micromeritics developed its suite of particle size analysis instrumentation (the SediGraph® 5000ET, 5100, and 5120) over the next several years, Tony worked with sample cell and fluid handling design to improve repeatability and reproducibility of results. He participated in performance testing, final testing, and then test development, and he now assumes responsibility for all phases of the testing process.

During the development of the Saturn DigiSizer®, Tony became involved with its applications and sample dispersion, both in its later development stages and in assuming responsibility for training users in the field of laser particle size analysis.

With the development of the Elzone™ II 5390, Tony assumed responsibility for ensuring the compatibility of results with earlier versions of this instrumentation and the smooth conversion of its user interface to align with that of the entire Micromeritics line of instruments. Similarly, with the introduction of the Particle Insight instrument, Tony was responsible for evaluating its operation and reliability as an offering in the Particulate Systems line of products.

For many years, due to his background in chemistry and his intimate understanding of the Micromeritics product line, Tony has assumed the responsibility for technical training of both customers and Micromeritics personnel, covering all aspects of education from theory of operation to report generation.

In his current role as the Director of Product Integrity and Performance, as well as in his prior roles as Senior Product Scientist and Laboratory Manager, he has provided ongoing applications support to customers for particle size instrumentation as well as for other product lines, including the physisorption and chemisorption instrumentation and pycnometer instrumentation.
