As the academic year officially kicks off, professors have started moving in and Rice University has opened its largest core campus research facility, The Ralph S. O’Connor Building for Engineering and Science.

The 250,000-square-foot building is the new home for four key research areas at Rice: advanced materials, quantum science and computing, urban research and innovation, and the energy transition. The university aims for the space to foster collaboration and innovation between the disciplines.

"To me it really speaks to where Rice wants to go as we grow our research endeavors on campus," Michael Wong, Chair of the Department of Chemical and Biomolecular Engineering, whose lab is located in the new facility, said in a video from Rice. "It has to be a mix of engineering and science to do great things. We don’t want to do good things, we want to do great things. And this building will allow us to do that."

At $152 million, the state-of-the-art facility features five floors of labs, classrooms and seminar rooms. Common spaces and a cafe encourage communication between departments, and the top level is home to a reception suite and outdoor terrace with views of the Houston skyline.

It replaces 1940s-era Abercrombie Engineering Laboratory on campus, which was demolished in 2021 to make way for the new facilities. The iconic sculpture "Energy" by Rice alumnus William McVey that was part of the original building was preserved with plans to incorporate it into the new space.

The new building will be dedicated to its namesake Ralph O'Connor on Sept. 14 in Rice's engineering quad at 3 p.m. O'Connor, a Johns Hopkins University grad, became a fan Rice when he moved to Houston to work in the energy industry in the 1950s.

The former president and CEO of the Highland Oil Company and founder of Ralph S. O’Connor & Associates left the university $57 million from his estate after he died in 2018. The gift was the largest donation from an estate in Rice's history and brought his donations to the university, including those to many buildings on campus and endowments and scholarships, to a total of $85 million.

“How fitting that this building will be named after Ralph O’Connor,” Rice President Reginald DesRoches said in a statement last summer. “He was a man who always looked to the future, and the future is what this new engineering and science building is all about. Discoveries made within those walls could transform the world. Anybody who knew Ralph O’Connor knows he would have loved that.”

The dedication event will be open to the public. It will feature remarks from DesRoches, as well as Rice Provost Amy Dittmar, Dean of the Wiess School of Natural Sciences Thomas Killian, Chair of the Rice Board of Trustees Robert Ladd and Dean of the George R. Brown School of Engineering Luay Nakhleh. A reception and tours of the new building will follow.

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
