(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.
The annual Center for Innovation, Technology and Entrepreneurship (CITE) 100K Venture Competition and Exposition will be held on the Main Campus on Dec. 1. Twenty-eight teams from across the university will exhibit their project; six teams will compete for a prize pool of more than $100,000 in funding to launch their new venture / company. More than 650 students have participated in launching new technology ventures.

This concert features 50 community children performing music in the UTSA Downtown String Project Winter Concert. The children, led by UTSA music students studying to be music teachers, will join together in playing the Theme from Batman at their concert. The Batman of San Antonio, a local celebrity figure, will make an appearance at the concert. This event is free.

As touch screens and e-books demand more and more attention from both casual readers and scholars, many people say the handwriting is on the wall for the printed page.
At UTSA, the handwriting is on the wall for a library that doesn't have any printed books.
Since March 2010, the bookless library in the Applied Engineering and Technology Building has given UTSA students an innovative way to read, research and work with each other to solve problems.
With ultra-modern furniture and a décor featuring desktop computers, scanners and LCD screens, the AET Library is designed to engage students in an online format. But it also offers group study niches and study rooms with whiteboards and glass walls on which students can write. The space encourages teamwork, communications and problem solving for the next generation of scientists and professional engineers.
Did you know? The UTSA AET Library is the nation's first completely bookless library on a college or university campus. It served as a model for Bexar County's first-in-the-nation public bookless library system and one of its branches, the Dr. Ricardo Romo BiblioTech.
The University of Texas at San Antonio is dedicated to the advancement of knowledge through research and discovery, teaching and learning, community engagement and public service. As an institution of access and excellence, UTSA embraces multicultural traditions and serves as a center for intellectual and creative resources as well as a catalyst for socioeconomic development and the commercialization of intellectual property - for Texas, the nation and the world.
To be a premier public research university, providing access to educational excellence and preparing citizen leaders for the global environment.
We encourage an environment of dialogue and discovery, where integrity, excellence, inclusiveness, respect, collaboration and innovation are fostered.
