2 sustainability-focused student startups named to Houston accelerator

ready to grow

Rice University's Liu Idea Lab for Innovation & Entrepreneurship, or Lilie, has named eight teams to the second cohort of the Lilie Summer Venture Studio, and two have sustainability as a goal.

According to Rice, the 12-week program received a record number of applications, that spanned the campus' degree offerings.

“We are thrilled to see such a high level of interest and excitement from Rice students for a high-growth venture accelerator,” Kyle Judah, executive director of Lilie, said in a statement. “The diversity and creativity in this year's applications were truly inspiring, and we’re excited to support these promising ventures with the resources and mentorship they need to hit escape velocity and create the next generation of pillar companies for Houston, Texas and the world.”

The selected teams will receive $15,000 in non-dilutive funding from the accelerator, along with access to coworking space and personalized mentorship in the Liu Idea Lab.

Coflux Purification, a patent-pending in-stream module that breaks down PFAS using a novel absorbent for chemical-free water, was named to the cohort, as was Solidec, a technology platform that extracts molecules from water and air, transforms them into pure chemicals and fuels without any carbon emissions.

Here are the rest of the teams for the 2024 Lilie Summer Venture Studio:

Docflow, focused on streamlining residency shift scheduling
JewelVision, building virtual fitting rooms for jewelry e-commerce retailers using generative AI
Levytation, using data science and AI to answer critical questions about sales and customers for coffee shop management
OnGuard, a marketplace to book off-duty police officers and security professionals
Roster, leverages data on athletes in the NCAA Transfer Portal to automatically send updates on players to coaches
Veloci, a running shoe venture that addresses common pains through shoe design

Lilie launched the Summer Venture Studio last year. According to Rice, two out of the six teams selected, Helix Earth Technologies and Tierra Climate, which both also tackle sustainability challenges, raised venture capital funds after completing the accelerator program.

Helix Earth Technologies also went on to earn the inaugural TEX-E Prize at CERAWeek in 2023.

“The track record of our Summer Venture Studio Accelerator speaks for itself, despite being early in our second year," Taylor Anne Adams, head of venture acceleration programs at the Liu Idea Lab, said in a statement. "This is the power of entrepreneurship programming that is designed by founders, for founders, that happens at the Liu Idea Lab.”

Last year, Lilie also named 11 successful business leaders with ties to Houston to its first Lilie’s Leadership Council. Each agreed to donate time and money to the university’s entrepreneurship programs.

3 Houston sustainability startups score prizes at Rice University pitch competition

seeing green

A group of Rice University student-founded companies shared $100,000 of cash prizes at an annual startup competition — and three of those winning companies are focused on sustainable solutions.

Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge, hosted by Rice earlier this month, named its winners for 2024. HEXASpec, a company that's created a new material to improve heat management for the semiconductor industry, won the top prize and $50,000 cash.

Founded by Rice Ph.D. candidates Tianshu Zhai and Chen-Yang Lin, who are a part of Lilie’s 2024 Innovation Fellows program, HEXASpec is improving efficiency and sustainability within the semiconductor industry, which usually consumes millions of gallons of water used to cool data centers. According to Rice's news release, HEXASpec's "next-generation chip packaging offer 20 times higher thermal conductivity and improved protection performance, cooling the chips faster and reducing the operational surface temperature."

A few other sustainability-focused startups won prizes, too. CoFlux Purification, a company that has a technology that breaks down PFAS using a novel absorbent for chemical-free water, won second place and $25,000, as well as the Audience Choice Award, which came with an additional $2,000.

Solidec, a company that's working on a platform to produce chemicals from captured carbon, and HEXASpec won Outstanding Achievement in Climate Solutions Prizes, which came with $1,000.

The NRLC, open to Rice students, is Lilie's hallmark event. Last year's winner was fashion tech startup, Goldie.

“We are the home of everything entrepreneurship, innovation and research commercialization for the entire Rice student, faculty and alumni communities,” Kyle Judah, executive director at Lilie, says in a news release. “We’re a place for you to immerse yourself in a problem you care about, to experiment, to try and fail and keep trying and trying and trying again amongst a community of fellow rebels, coloring outside the lines of convention."

This year, the competition started with 100 student venture teams before being whittled down to the final five at the championship. The program is supported by Lilie’s mentor team, Frank Liu and the Liu Family Foundation, Rice Business, Rice’s Office of Innovation, and other donors

“The heart and soul of what we’re doing to really take it to the next level with entrepreneurship here at Rice is this fantastic team,” Peter Rodriguez, dean of Rice Business, adds. “And they’re doing an outstanding job every year, reaching further, bringing in more students. My understanding is we had more than 100 teams submit applications. It’s an extraordinarily high number. It tells you a lot about what we have at Rice and what this team has been cooking and making happen here at Rice for a long, long time.”

UH lands $1M NSF grant to train future critical minerals workforce

workforce pipeline

The University of Houston has launched a $1 million initiative funded by the National Science Foundation to address the gap in the U.S. mineral industry and bring young experts to the field.

The program will bring UH and key industry partners together to expand workforce development and drive research that fuels innovation. It will be led by Xuqing "Jason" Wu, an associate professor of information science technology.

“The program aims to reshape public perception of the critical minerals industry, highlighting its role in energy, defense and advanced manufacturing,” Wu said in a news release. “Our program aims to showcase the industry’s true, high-tech nature.”

The project will sponsor 10 high school students and 10 community college students in Houston each year. It will include industry mentors and participation in a four-week training camp that features “immersive field-based learning experiences.”

“High school and community college students often lack exposure to career pathways in mining, geoscience, materials science and data science,” Wu added in the release. “This project is meant to ignite student interest and strengthen the U.S. workforce pipeline in the minerals industry by equipping students with technical skills, industry knowledge and career readiness.”

This interdisciplinary initiative will also work with co-principal investigators across fields at UH:

Jiajia Sun, Earth & Atmospheric Sciences
Yan Yao and Jiefu Chen, Electrical and Computer Engineering
Yueqin Huang, Information Science Technology

According to UH, minerals and rare earth elements have become “essential building blocks of modern life” and are integral components in technology and devices, roads, the energy industry and more.
