Houston-headquartered NOV Inc. announced the appointment of a former energy transition executive to its board of directors.

Patricia Martinez was named to NOV’s board, and the appointment is effective as of March 6. She was formerly chief energy transition officer of Enerflex Ltd.

“We are delighted to welcome Patricia Martinez to NOV’s board of directors,” Clay Williams, chairman, president, and CEO of NOV, says in a news release. “Patricia brings extensive industry experience to our board, including growing energy businesses in international markets, and more recently guiding and developing projects within the energy transition ranging from CCUS to hydrogen to biogas. Her deep insights into emerging energy opportunities will help shape NOV’s energy transition strategy.”

Martinez, who also serves as a director of Par Pacific Holdings Inc., holds a bachelor’s degree in business administration and marketing from Universidad Argentina de la Empresa and an MBA from Houston Christian University.

With the appointment, NOV Inc.’s board of directors now has of ten directors, nine of whom are independent members.

A View From HETI

A new study from researchers at Rice University, published in Nature Communications, could lead to future advances in superconductors with the potential to transform energy use.

The study revealed that electrons in strange metals, which exhibit unusual resistance to electricity and behave strangely at low temperatures, become more entangled at a specific tipping point, shedding new light on these materials.

A team led by Rice’s Qimiao Si, the Harry C. and Olga K. Wiess Professor of Physics and Astronomy, used quantum Fisher information (QFI), a concept from quantum metrology, to measure how electron interactions evolve under extreme conditions. The research team also included Rice’s Yuan Fang, Yiming Wang, Mounica Mahankali and Lei Chen along with Haoyu Hu of the Donostia International Physics Center and Silke Paschen of the Vienna University of Technology. Their work showed that the quantum phenomenon of electron entanglement peaks at a quantum critical point, which is the transition between two states of matter.

“Our findings reveal that strange metals exhibit a unique entanglement pattern, which offers a new lens to understand their exotic behavior,” Si said in a news release. “By leveraging quantum information theory, we are uncovering deep quantum correlations that were previously inaccessible.”

The researchers examined a theoretical framework known as the Kondo lattice, which explains how magnetic moments interact with surrounding electrons. At a critical transition point, these interactions intensify to the extent that the quasiparticles—key to understanding electrical behavior—disappear. Using QFI, the team traced this loss of quasiparticles to the growing entanglement of electron spins, which peaks precisely at the quantum critical point.

In terms of future use, the materials share a close connection with high-temperature superconductors, which have the potential to transmit electricity without energy loss, according to the researchers. By unblocking their properties, researchers believe this could revolutionize power grids and make energy transmission more efficient.

The team also found that quantum information tools can be applied to other “exotic materials” and quantum technologies.

“By integrating quantum information science with condensed matter physics, we are pivoting in a new direction in materials research,” Si said in the release.
