Welch Foundation gives $150K to UTSA for inorganic chemistry research

(June 6, 2011)--Zachary Tonzetich, assistant professor of chemistry in the UTSA College of Sciences, will receive $150,000 from The Welch Foundation over the next three years to study the reactivity of transition metals such as iron, cobalt and manganese with hydrogen sulfide.

Tonzetich is the fifth UTSA chemistry professor with active funding from The Welch Foundation, following department chair Waldemar Gorski, associate professors Banglin Chen and Cong-Gui Zhao, and assistant professor Doug E. Frantz.

Transition metals, such as iron found in blood, exist in the body in regulated concentrations often bound to proteins. In general, metal ions can serve as signals for biological processes or as catalysts, which make chemical reactions more efficient and higher yielding using less energy. Tonzetich's team will study how transition metal ions react with hydrogen sulfide, which serves as a signaling agent in the body and is believed to play a role in hibernation.

"It is critical that we gain a better understanding of how hydrogen sulfide binds to transition metals in the body, what the nature of these bonds are, and how the body uses hydrogen sulfide at a molecular level," said Tonzetich. "With the support of The Welch Foundation, we will examine the fundamental coordination chemistry of hydrogen sulfide. As we learn more about how this small molecule interacts with transition metals, we hope to be able to provide biologists and biochemists with a more complete picture of its chemistry in the body."

Fundamental chemistry research, such as Tonzetich's, is critical to the development of new drugs that target and manipulate the body's many biological pathways. Pfizer's Viagra, for example, is based on fundamental research demonstrating that nitric oxide affects blood vessel constriction. Cancer drugs and vaccines target other pathways in the body.

Tonzetich joined the UTSA Department of Chemistry last fall after completing his doctorate degree in 2007 and a subsequent three-year postdoctoral fellowship at MIT. His research specialties include synthetic inorganic and bioinorganic chemistry, catalysis, structure and bonding, spectroscopy, kinetics and reaction mechanisms.

The Welch Foundation, based in Houston, is one of the nation's largest and oldest private funding sources for chemistry research. It primarily supports researchers at Texas institutions of higher education.

UTSA researcher is a star behind the cloud

A revolution in cloud computing is underway, and Ravi Sandhu believes it will be much bigger than the PC and Internet revolutions that have already changed the way we live. Sandhu, director of the UTSA Institute for Cyber Security, says UTSA is taking a leadership role in tackling three fundamental cloud technology problems: how to build and operate the cloud, how to use it profitably for diverse applications and how to keep it secure.

Sandhu, the Lutcher Brown Distinguished Chair in Cyber Security in the College of Sciences, and Ram Krishnan, assistant professor of electrical engineering in the UTSA College of Engineering, are funded by a $500,000 grant from the National Science Foundation to improve cloud security.

Did you know? Sandhu, a world-renowned cybersecurity expert, holds 30 patents, has authored more than 250 papers and been cited more than 30,000 times.
