Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research news, two Houston institutions are working on clean energy innovation thanks to new technologies.

Rice University team develops seeds for growing solar energy collectors

Man-made solar panels are continuing to be affixed to rooftops everywhere, but scientists at Rice University have just figured out a way to grow solar energy collectors in a more efficient way than ever before.

3D halide perovskite photovoltaic devices have been developed relatively reliably, but the Rice engineers have created microscopic seeds for growing 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight, according to a release from Rice.

"We've come up with a method where you can really tailor the properties of the macroscopic films by first tailoring what you put into solution," said study co-author Aditya Mohite, an associate professor of chemical and biomolecular engineering and of materials science and nanoengineering at Rice. "You can arrive at something that is very homogeneous in its size and properties, and that leads to higher efficiency. We got almost state-of-the-art device efficiency for the 2D case of 17%, and that was without optimization. We think we can improve on that in several ways."

The study was published online in Advanced Materials by Mohite and his fellow chemical engineers from Rice's Brown School of Engineering. The seeds can be used to grow homogenous thin films that proved both efficient and reliable, a previously problematic combination for devices made from either 3D or 2D perovskites.

"Homogeneous films are expected to lead to optoelectronic devices with both high efficiency and technologically relevant stability," he says.

The process is more efficient and effective, as well as being cheaper. The Department of Energy's Office of Energy Efficiency and Renewable Energy and the Academic Institute of France and the Office of Naval Research supported the project.

Houston researchers are finding ways to improve EV batteries

Only a small fraction of vehicles on the road these days are electric — but that's going to change. It's projected that EVs will make up 30 percent of on-road vehicles in 2030. A team of scientists at the University of Houston are focusing on improving EV batteries — a major key in the commercialization of these greener vehicles.

The UH team — Yan Yao, Cullen Professor of electrical and computer engineering at the Cullen College of Engineering at the University of Houston, and UH post doctorate Jibo Zhang — are taking on this challenge with Rice University colleagues — Zhaoyang Chen, Fang Hao, Yanliang Liang of UH, Qing Ai, Tanguy Terlier, Hua Guo and Jun Lou.

In a recently published paper in Joule, the team demonstrated a two-fold improvement in energy density for organic-based, solid state lithium batteries by using a solvent-assisted process to alter the electrode microstructure, according to a news release from UH.

"We are developing low-cost, earth-abundant, cobalt-free organic-based cathode materials for a solid-state battery that will no longer require scarce transition metals found in mines," says Yao in the release. "This research is a step forward in increasing EV battery energy density using this more sustainable alternative."

Yao, who is also Principal Investigator with the Texas Center for Superconductivity at UH, explains that there is increasing concern about the supply chain of lithium-ion batteries in the United States.

"In this work, we show the possibility of building high energy-density lithium batteries by replacing transition metal-based cathodes with organic materials obtained from either an oil refinery or biorefinery, both of which the U.S. has the largest capacity in the world," he goes on to say.

The cost of EV batteries declined to nearly 10 percent of their original cost over the past decade, and innovation and research like this project are only going to make EVs more commercially viable. The research was funded by the US Department of Energy's Office of Energy Efficiency and Renewable Energy as part of the Battery 500 Consortium.

Houston solar energy exec shines light on company growth and IPO

HOUSTON INNOVATORS PODCAST EPISODE 15

It was all about the timing for John Berger, founder and CEO of Sunnova, a Houston-based residential solar energy company.

When he founded his company in 2012 in Houston, solar energy wasn't the trendy sustainability option it is today, but Berger saw the potential for technology within the industry. So, with a lot of perseverance and the right team behind him, he scaled Sunnova through nationwide expansion, billions of money raised, and a debut on the stock market last July — something that also happened with great timing.

About 72 hours after Sunnova went public last July, the Federal Reserve System announced it was going to cut rates. Additionally, Sunnova's IPO occurred ahead of WeWork's failed IPO.

"We went public in a market that still isn't back open again, I think, for IPOs," Berger says on this week's episode of the Houston Innovators Podcast. "We had pretty good timing when we went out the door."

However great the timing was, Sunnova's success is built on the hard work and skills of the company's employees, Berger explains on the podcast, and now running a public company requires a dynamic leader.

"I really look at myself and how I can change myself," Berger says. "I'm a different CEO today than I was 12 months ago, and hopefully I'll be a different CEO in 12 months, because the company demands it."

In the episode, Berger lifts the curtain on Sunnova's IPO, explains where he sees the solar energy industry headed, how battery storage technology has evolved, and why he's not worried about who ends up in the White House.

Houston expert: How to embrace cognitive diversity in the workplace

guest column

Everyone thinks and processes information in their own unique way. Cognitive diversity refers to these differing styles, perspectives, and problem-solving approaches among individuals in a group. Cognitive diversity, in today’s evolving workplace, is recognized as a valuable asset. Teams that are cognitively diverse can enhance their innovation, creativity and overall performance. The challenge comes with group dynamics when there may be communication barriers, conflicts and biases.

Effective strategies to consider for managing cognitive diversity in the workplace are as follows.

Communicate and take action

Business leaders who recognize and embrace the value of diverse perspectives and cognitive styles are better able to manage any challenges that may arise within the organization. Leaders and managers should communicate the importance of cognitive diversity to their team and encourage employees to share their unique viewpoints and approaches. This also means managers should be aware of their own biases and avoid making assumptions about people in order to create a more inclusive environment.

When a company uses hiring practices that embrace cognitive diversity, brings forth varying perspectives and ways of problem solving. Identifying those who may think differently than others or who may challenge the status quo is many times identifying those who will become the company’s best innovators. Embracing a diverse group of thinkers will help foster a culture of inclusivity, open-mindedness, and innovation.

Encourage collaboration

Collaboration is key to the success of any team. When working together, different cognitive styles can complement each other’s strengths and compensate for any weaknesses. Studies show cognitive diversity within groups can accelerate learning and performance when faced with challenges. In order to get through some of businesses’ most complex situations, there needs to be different perspectives and viewpoints.

For the most innovative thoughts to be heard, people must have the space to raise their hand and speak up, but also, people must actively listen to what the person has to say. Managers should work to create opportunities for collaboration, whether it is building cross-functional teams or other group projects and encourage employees to openly communicate and give feedback to improve the outcome.

Provide training and development

Training and development opportunities focused on cognitive diversity can help employees understand their own communication styles and the communication styles of others. By educating and applying, taking action steps after training will help reduce biases and misunderstandings. Additionally, these trainings can increase empathy, which does not come natural for some, and respect among team members.

Businesses should also evaluate their current company training programs to make certain they are inclusive of different learning styles, such as using infographics for visual learners or having hands-on demonstrations. Another consideration is to incorporate self-paced learning into training and development plans. No matter the type of training, solicit feedback, and take it under consideration to continuously improve how teams can develop their skills. Feedback that is thoughtfully considered and implemented leads to more engaged employees overall.

Manage conflicts

Conflicts are inevitable; however, organizations should set clear expectations and policies for performance and behavior. Unfortunately, conflict can be exacerbated in a diverse environment. Managers should be primed with knowledge on how to resolve conflicts and help facilitate constructive conversations among both parties. Also, managers should know when to reach out for help from their supervisor or human resources.

For business leaders to successfully manage cognitive diversity in the workplace, they must intentionally work to develop a culture that embraces the differences in others. Savvy business leaders will enlist the help of their HR team or outside council, such as a professional employer organization, to ensure their strategies and policies for managing a cognitively diverse workplace are inclusive.

Most importantly, when the company culture embodies a diverse, equitable, and inclusive workplace, the employees tend to have the same values, especially when the expectations are clearly set. As a result, the business will become a more innovative and engaging environment where employees know how to leverage their own strengths and the strengths of others, no matter their cognitive style.

Houston doesn't have too many unicorns — startups valued at $1 billion or more — in its innovation ecosystem, but Solugen, a sustainable chemicals company, is among the elite group. Gaurab Chakrabarti, the CEO and co-founder of the company, joined Houston House by the Greater Houston Partnership, to share his story on the SXSW stage.

“You do make your own luck, but you have to be putting in the work to do it," Chakrabarti says, adding that it's not an easy thing to accomplish. “There are things you can be doing to increase your luck surface area."

He shared several lessons he learned on his founder journey in the discussion. Read more.

Founded in San Diego, rBIO recently relocated to Houston and has big plans for settling in the city, says Cameron Owen, the company's co-founder and CEO.

“Companies from California like us and the coastal areas were converging here in Houston and creating this new type of bioeconomy,” he tells InnovationMap.

He shares that Houston wasn't originally on his radar, until it was. A visit turned into a relocation, and it's just the beginning for the biotech startup that's focused on using synthetic biology for pharmaceuticals. Read more.

Innovative company with ownable multi-use concept shares details on Houston facility opening

coming soon

To some, Houston’s lack of zoning laws is a beautiful thing. The first time Byron Smith visited the city, he remarked on seeing a church, school, office building, and strip club all in startlingly close proximity.

At the time, the Sydney-born entrepreneur, whose previous experience was primarily in the automotive industry, was living in New York. But he fell in love with Space City.

“I was like, ‘We need to be in Texas,” he recalls, referring to expanding his next venture, XSpace, to the Lone Star State.

XSpace is a multi-use commercial condo building that allows entrepreneurs to own a home for their business.

“We’re a cool warehouse space that you own,” Smith explains, calling it “evolutionary space” where a business can grow from the roots up.

Though his family business was commercial real estate, Smith first dipped his toe into working with buildings with last year’s opening of the first XSpace in Austin. The city became “a natural fit” for the first project because Smith identified it as “a little bit more receptive to new things.” But Houston was part of the plan from the very beginning.

Located at 7022 Old Katy Road — close to both an escape room and an Aston-Martin dealership, among other diverse businesses — the Houston XSpace’s 86 units are already between 20- and 30-percent pre-sold, says Smith.

Confirmed owners of the spaces include “car guys,” such as a car-wrapping business; media companies that plan to podcast from XSpace; and an interior design company. Smith says that he’s been impressed with Houston’s depth of market.

“We’re trying really hard not to be rich-guy car condo stuff,” explains Smith. “It’s about cool, interesting people who are successful or are going to be successful.”

Though multiple businesses will all operate in XSpace, don’t think of it as a coworking space. In fact, coworking space is just a component included in the package of what owners get when they purchase part of XSpace. That’s inside the Owner’s Lounge, a flexible 4,000-square-foot area.

Each unit has natural light, but also metered electric and hot and cold running water. The whole facility is air-conditioned and well-ventilated and offers 24/7 access. The building is triple-gated for optimum security and includes a backup generator to ensure that owners will be able to work even in the case of another power grid failure.

Smith says that groundbreaking for XSpace will take place in seven weeks. Likely, owners will be able to start moving into the building in the summer of 2024. Until then, Smith says to expect some “sexy announcements” about upcoming partnerships and additional XSpace sites.

Though Smith says that global expansion isn’t yet in the plans for XSpace, “North American domination” is.

“All the cool cities, we’re going to be there,” he says. And it was all inspired by the coolest city of all and its eclectic business landscape.
