A new report looked into compensation at startups across the country, and the Texas market fared pretty well overall. The report from Carta, a San Francisco, California-based technology company that specializes in capitalization table management and valuation software, factored in data using more than 127,000 employee records from startups that use Carta Total Comp, the premier compensation management platform for private companies.

"At Carta, we see it as our responsibility to share the insights that come from an unmatched amount of data about the private market," per the report. "That includes data on startup headcount, payroll and equity metrics, salary medians, and remote work."

The greater Houston area ranked No. 15 in the list, which lands it at the top of the third tier just ahead of Dallas. As the chart depicts, Houston has 88 percent of the compensation of the top market — which this year is a four-way tie between the San Francisco, New York, San Jose, and Seattle areas. Austin landed in the middle of the top tier, and San Antonio snuck into the bottom of the third tier. The full report with national trends is online.

Rice University team develops eco-friendly method to destroy 'forever chemicals' in water

clean water research

Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”

Axiom Space announces new CEO amid strategic leadership change

new leader

Six months after promoting Tejpaul Bhatia from chief revenue officer to CEO, commercial space infrastructure and human spaceflight services provider Axiom Space has replaced him.

On Oct. 15, Houston-based Axiom announced Jonathan Cirtain has succeeded Bhatia as CEO. Bhatia joined Axiom in 2021. Cirtain remains the company’s president, a role he assumed in June, according to his LinkedIn profile.

In a news release, Axiom said Cirtain’s appointment as CEO is a “strategic leadership change” aimed at advancing the company’s development of space infrastructure.

Axiom hired Cirtain as president in June, according to his LinkedIn profile. The company didn’t publicly announce that move.

Kam Ghaffarian, co-founder and executive chairman of Axiom, said Cirtain’s “proven track record of leadership and commitment to excellence align perfectly with our mission of building era-defining space infrastructure that will drive exploration and fuel the global space economy.”

Aside from praising Cirtain, Ghaffarian expressed his “sincere gratitude” for Bhatia’s work at Axiom, including his leadership as CEO during “a significant transition period.”

Bhatia was promoted to CEO in April after helping Axiom gain more than $1 billion in contracts, Space News reported. He succeeded Ghaffarian as CEO. Axiom didn’t indicate whether Bhatia quit or was terminated.

Cirtain, an astrophysicist, was a senior executive at BWX Technologies, a supplier of nuclear components and fuel, for eight years before joining Axiom. Earlier, Cirtain spent nearly nine years in various roles at NASA’s Marshall Space Flight Center in Huntsville, Alabama. He previously co-founded a machine learning company specializing in Earth observation.

“Axiom Space is pioneering the commercialization of low-Earth orbit infrastructure while accelerating advancements in human spaceflight technologies,” Cirtain said. “I look forward to continuing our team’s important work of driving innovation to support expanded access to space and off-planet capabilities that will underpin the future of space exploration.”

Among other projects, Axiom is developing the world’s first commercial space station, creating next-generation spacesuits for astronauts and sending astronauts on low-Earth orbit missions.
