Rice University has partnered up with the Texas Department of Transportation's ConnectSmart program to help students find eco-friendly travel options in the Houston area.

ConnectSmart, which launched in Houston in 2022, is a Houston-based app that uses live data from local transportation authorities to suggest better travel times, routes and transportation methods to users. It also allows users to purchase bus and METRO tickets, and find BCycle e-bikes, directly in the app.

As of April 1, Rice students and those with a Rice email address can now sign up for ConnectSmart and will receive free or subsidized Metro QCards, according to an announcement from the university.

"ConnectSmart is an app that allows Rice users and people who sign up with their Rice email address to set up carpooling groups as well as figure out alternative means of transportation to and from wherever they’re going,” Kristianna Bowles, sustainability program coordinator in the Office of Sustainability, said in the statement. “That includes access to the METRORail, bus stops and cycling routes. It’s going to be a good tool for us to promote alternative and sustainable transportation features as well as increase equity, especially around our hourly employees who come in earlier in the morning or who may not have access to a vehicle.”

Bowles adds that the university also hopes ConnectSmart will help the Rice community explore the Greater Houston Area.

“Rice’s students are located in the heart of one of the largest cities in the country, so this helps foster students’ ability to explore Houston’s culture through foods, the arts and public events,” she added.

ConnectSmart also provides users with access to Tow and Go’s no-cost emergency roadside services, helps them connect with Houston's miles of bike lanes and connect multiple modes of transportation to beat Houston traffic. The new ConnectSmart Employer Commute Suite also aims to help workplaces increase their staff’s access to affordable and sustainable transportation, while also collecting data on commuting and decarbonization initiatives to incorporate into ESG reporting.

The app is the result of a partnership between TxDOT, the Federal Highway Administration , the Houston-Galveston Area Council, City of Houston, Houston METRO, Houston TranStar, Tow and Go, BCycle, Conroe Connection, Fort Bend Transit and Harris County Transit. ConnectSmart's partnership with Rice was part of the university's Earth Month.

Last year, Houston got a break on a list of U.S. cities with the worst commutes, ranking only at No. 23.

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.
