A magnetic field can make it easier, or harder, for electricity to flow through a material. A new paper from the Baranets Research Group, led by graduate student Md. Rashed Alam in collaboration with colleagues in the LSU Department of Physics and Astronomy, explores a compound that does both, depending on temperature.

The team discovered a new family of crystalline materials with unusually complex crystal structures and extensive disorder. Combined with intriguing electrical and magnetic properties, this work opens opportunities to explore new magnetic materials and materials that convert heat into electricity.

Published in the 𝘑𝘰𝘶𝘳𝘯𝘢𝘭 𝘰𝘧 𝘔𝘢𝘵𝘦𝘳𝘪𝘢𝘭𝘴 𝘊𝘩𝘦𝘮𝘪𝘴𝘵𝘳𝘺 𝘊, the paper is part of the JMCC Emerging Investigators 2027 themed collection.

Small structures, big possibilities. 🔬

Assistant Professor Sviatoslav Baranets and graduate student Thimira Kandabadage explore an underexplored family of rare-earth materials in a new chapter of the 𝘏𝘢𝘯𝘥𝘣𝘰𝘰𝘬 𝘰𝘯 𝘵𝘩𝘦 𝘗𝘩𝘺𝘴𝘪𝘤𝘴 𝘢𝘯𝘥 𝘊𝘩𝘦𝘮𝘪𝘴𝘵𝘳𝘺 𝘰𝘧 𝘙𝘢𝘳𝘦 𝘌𝘢𝘳𝘵𝘩𝘴, a scientific reference series with nearly 50 years of history.

Their chapter examines how incorporating different types of negatively charged ions within the same crystal creates a wide variety of crystal structures, with potential applications in semiconductor technologies, optics, and magnetic materials. It also highlights challenges in making these materials and opportunities for future research.

He first came to LSU as an undergraduate in 1966. When Dr. Frank Fronczek returned in 1976, he expected to stay one year. That year became a 50-year career helping shape generations of chemistry research.

From revealing thousands of crystal structures to guiding students through their first discoveries, Dr. Fronczek has left a lasting mark on LSU and the worldwide crystallography community.

As he enters retirement, one thing is clear: he’s still bleeding Purple & Gold. 💜💛

Associate Professor Noémie Elgrishi received an NSF EPSCoR Research Fellows award to investigate how metal-organic cages capture PFAS and other charged contaminants.

Through a collaboration with Dr. Kristina Håkansson at the National High Magnetic Field Laboratory, the research team will examine why some cages capture certain molecules more effectively than others. Their findings could guide the development of more selective, reusable materials for water purification.💧

Congratulations to the recipients of the Neil and Arlene Kestner College of Science Superior Graduate Student Scholarship! 🎉

The scholarship recognizes graduate students for their achievements and promise in materials science. It honors the late LSU Professor Emeritus Neil Kestner, a pioneer in theoretical physical and computational chemistry whose influential work on electron transfer was recognized by Rudolph “Rudy” Marcus during his 1992 Nobel Prize acceptance speech. Kestner was inducted into the LSU College of Science Hall of Distinction in 2017.

This year’s recipients are:
▪️Thimira Kandabadage Don, Chemistry PhD student, Baranets Research Group
▪️ Mohammed Mehedi Hasan, Physics PhD student, Magana-Loaiza Research Group
▪️ Md. Abdullah Al Mahmud, Chemistry PhD student, Pojman Research Group

Congratulations to these outstanding #LSUScience graduate students!

Congratulations to Gayomi Samarakoon, a PhD student in @lsuchemistry and a member of the Baranets Research Group, on receiving the Adah Proctor Sturgis Graduate Scholarship in Chemistry and Biochemistry!

The scholarship recognizes graduate students for their achievements and promise in chemistry and biochemistry. It honors Adah Proctor Sturgis, a trailblazing chemist who worked for the Ethyl Corporation. Her grandson, LSU alumnus Dr. Erich Sturgis, helped establish the scholarship to honor his grandmother and pioneering women in science.

Congratulations, Gayomi! by @lsuchemistry

Congratulations to Dr. Víctor García-López, assistant professor from the @lsuchemistry on receiving an NSF CAREER Award! 🎉

Dr. García-López will study how light-responsive molecular machines can reshape lipid membranes and control their electrical properties. The research could help lay the foundation for bioinspired materials that emulate aspects of learning and memory while providing interdisciplinary training for LSU students and expanding STEM outreach across Louisiana.

⭐Student Spotlight⭐
Samuel Owoso, Chemistry Graduate Student

Meet Samuel Owoso, a 5th-year Ph.D. candidate in the Zhang Research Group studying biomacromolecular and polymer chemistry. His research explores how molecular evolution leads to the emergence of functional protoproteins and investigates the dynamic mechanisms that enable sequence selection at life’s origin. Samuel chose chemistry because it allows him to uncover how molecular interactions give rise to function and to translate those insights into new materials, one monomer at a time.

After graduation, Samuel hopes to pursue a career as a materials R&D scientist, creating functional and sustainable polymers that enable innovations in energy, biotechnology, and next-generation electronics. Outside the lab, he enjoys playing badminton, writing music, singing, and experimenting with new recipes in the kitchen. by @lsuchemistry

Controlling how and when molecules cross cell membranes is a challenge in drug delivery and biomedical engineering. Greater precision could enable therapies that activate only where and when they’re needed, reducing side effects and improving effectiveness.

In a new paper, the García-López Research Group reports a photoswitchable rotaxane that changes shape in response to light, doubling membrane permeability (29% → 59%) and demonstrating how light can precisely regulate molecular activity.

Their findings open new possibilities for light-responsive tools that could one day deliver drugs or modulate cells with pinpoint accuracy.
