See ya, CO2

Houston-based Cemvita Factory is unlike most startups. Before even knowing what industry they were going to affect, Moji Karimi and his sister, Tara, established their company, which uses synthetic photosynthesis — the process of turning carbon dioxide into glucose for plants.

"In some ways, this company started with the solution, rather than the problem," Moji Karimi, co-founder of Cemvita, says. "Then we said, 'if we could replicate photosynthesis, what problems can we solve?'"

Once the technology was set in place, Karimi, who has a background in oil and gas drilling, says he identified the energy industry in need of something like this. He says he saw an increased pressure on large energy companies to adapt sustainable ways to get rid of the CO2 that is produced as a result of drilling.

More and more companies are investing in a process called carbon dioxide capturing — but it's expensive and not yet cost efficient for energy companies to commit to. But that's changing. Karimi says the process that once cost $600 per ton of CO2 now can be found as cheap as $30.

With his sister's technology, Karimi says they can take that captured carbon dioxide and turn it into other chemicals too. Each oil and gas company client can specify what they want to turn it into and, for less than $100,000, Cemvita will run a pilot program for them. Cemvita sells the exclusive rights to the technology, but still maintains its IP.

"We go to these companies and say, 'What do you want to convert CO2 into?,'" Karimi says. "Then, we do a quick pilot in six months in our lab, and we show them the metrics. They decide if they want to scale it up."

What seemed like another obvious industry for this process was aerospace. Many companies involved in aerospace exploration have Mars on the mind, and the planet's atmosphere is over 95 percent carbon dioxide. Plus, Cemvita can provide a more sustainable way to dispose of CO2 onboard spacecrafts. The current practice is essentially just discarding it by filtering it off the spaceship.

Putting a system in place
Cemvita was founded in August of 2017 and used 2018 to really establish itself. The company took second place at Dubai's Mohammed bin Rashid Space Centre Innovation Challenge and completed the accelerator program at Capital Factory.

Realizing the process is new and without the backing of an educational institution, Karimi says he and his sister needed a way to answer any questions and concerns, so Tara wrote a book. "Molecular Mechanisms of Autonomy in Biological Systems" is published by Springer.

Karimi also lead a talk at Tudor Pickering Holt's Energy Disruptor conference. His discussion, "From Mars to Midland," garnered a lot of interest from energy professionals.

The future is now
Karimi says 2019 is all about execution. He never thought he and his sister would overlap their industries, but now there's more of a need of interdisciplinary collaboration than ever before.

"There are a lot of opportunities bringing a proven science or technology from one industry into another to solve problems," he says.

The company has growth plans this year. The team has bootstrapped everything financially so far, but is looking for its first funding round in the middle of 2019. And, as far as the Karimi siblings are concerned, they are in the exact right place to grow.

"We're in Houston, and we have a technology that is from biotech and have applications in the space industry and the energy industry," Karimi says. "There would not have been any better place for us in the country than Houston."

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
