Another Delaware-based small business — TalosTech in New Castle, Delaware — was also among those that gained DOE support. TalosTech, launched by Hassan Liu in a UD-based incubator formerly located at the Delaware Technology Park, is working to improve lithium-ion batteries, making them safer and more sustainable.

“For any small business owner, every new bit of money is a game-changer that frees them up to pursue bold new ideas in earnest,” said Secretary of Energy Jennifer M. Granholm, when the grant was announced earlier this year. “This funding will give awardees a much-needed boost as they channel their entrepreneurial spirit into tackling the climate crisis, deploying creative clean energy technologies and answering the biggest questions we have about the universe — all while creating new American jobs to sustain their communities.”

Almost half of the nation’s workers are employed by small businesses, and small businesses represent 99.9% of all U.S. business.

The awards are administered by DOE’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, established to encourage diverse communities to participate in technological innovation, as well as create a bridge between DOE-supported science breakthroughs and viable products and services for the commercial market. The funding comes through DOE’s Office of Science (SC), as well as the Advanced Research Projects Agency-Energy (ARPA-E).

“These are the types of investments we need to support scientific discovery and critical research in advanced manufacturing,” said U.S. Sen. Chris Coons of Delaware when the grant was announced.

Wagner’s invention is engineered for use with neutron-scattering techniques that exist at laboratories around the nation. These techniques allow scientists to analyze the motion of molecules to get a better understanding of what is happening in the tiniest places, inaccessible to other instrumentation.

The new instrument — which STF calls the RheoSurfR, reflecting its ability to analyze the motion of liquids — will provide three-dimensional insight into nanostructures and microstructures and their interactions with various liquids and gases.

This information has critical implications for medicine and industry.

What happens on the surfaces of lipids, for example — the building blocks of cellular membranes — can have significant implications for the success or side effects of biopharmaceuticals. Are molecules collecting or interfering with other cellular processes?

“If you look at monoclonal antibodies that are used in therapies for cancer or COVID, for example, what happens when these biopharmaceuticals meet an air/water interface?” Wagner said. “Can they be destroyed or aggregate or even become harmful?”

The answer until now has been: Who knows? That interaction has been too small to see by normal means, Wagner said. Using neutron-scattering techniques, however, scientists can see what happens and then decide what, if anything, needs to be done about it.

Analysis of other interactions will have high value for industry.

“In energy production, for example, where oil and water mix together, getting water out of the oil is a big problem,” Wagner said.

What happens when air and liquids mix has an effect on foams and foods — shampoos, for example, or cappuccino or beer.

Scientists will have new measurement capacities for many such interactions.

STF’s new device is small enough to be on a benchtop. It will be placed within the beamline of instruments in national laboratories and other research facilities, including the Center for High Resolution Neutron Scattering, which Wagner has been developing for the National Institute of Standards and Technology.
