Crystallography — the study of crystals and their structures — plays a key role in many scientific fields like materials science, biochemistry and pharmaceuticals.  

As the study of crystallography continues to evolve, researchers are working to better understand crystals and how they can be used.  

By using X-ray techniques, researchers can learn about the atomic structure of crystals. This information reveals material properties that will help with creating new compounds and advancing technological applications. 

Dr. Nikolay Gerasimchuk, a distinguished professor in the department of chemistry and biochemistry at Missouri State University, is one of these researchers. He recently delivered a keynote address at the VI Latin American Crystallographic Association (LACA) Meeting held in Montevideo, Uruguay.  

“Seeing the level of crystallographic understanding and the techniques employed by attendees was truly inspiring,” he said. 

From Ukraine to the U.S.

From Kiev, Ukraine, Gerasimchuk holds two doctorate degrees. He received his first PhD in Coordination Chemistry from Kiev State University in 1985. A few years later, he moved to the United States to pursue his second doctorate. In 1996, he earned his PhD in Bioinorganic Chemistry from the University of Kansas.  

His journey into crystallography began during his doctoral studies, where he developed a passion for synthesizing new compounds and studying their crystal structures.  

Over the years, Gerasimchuk has worked at various universities in the U.S. and abroad, gaining valuable experience in the field. He joined MSU in 2001 and in 2007, the university got its first advanced crystallographic equipment. This enabled him to study the crystals in more detail and at a faster pace.  

He could examine the first crystal structures of thallium, palladium, platinum, silver and antimony oximes-based compounds, which have useful biological properties. Knowledge of the exact structures of these compounds directed further studies in this area. 

Conference highlights

The LACA event brought together participants from 32 countries, showcasing a diverse range of research and collaboration.  

Gerasimchuk’s keynote speech focused on the historical development and future directions of inorganic and materials chemistry. He highlighted Missouri State’s contributions to the field and discussed how the university has positioned itself as a hub for advanced crystallographic research. 

During his presentation, Gerasimchuk addressed the broad scope of applications for crystallography, from electrical engineering to materials development. He also highlighted the importance of understanding crystalline structures for innovation in these areas. 

“The recognition from my peers and the potential for future collaborations were incredibly gratifying,” he said. “Several researchers expressed interest in visiting Missouri State to engage in joint research projects, indicating a promising avenue for expanding the university’s influence in the field.” 

The event featured a variety of sessions, including discussions on biochemical crystallography and the characterization of minerals. One notable aspect was a special competition that encouraged high school students to engage in science by growing crystals. This initiative not only fostered interest in the field, but also enabled younger generations to showcase their work. 

“This conference has reinforced the idea that global collaboration is essential for tackling complex scientific challenges,” Gerasimchuk said. “Together, we can push the boundaries of what’s possible in crystallographic research and its applications.”
