Nanofibers yield stronger, tougher carbon fiber composites

Researchers at the U.S. Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) have developed an innovative new technique using carbon nanofibers to enhance binding in carbon fiber and other fiber-reinforced polymer composites—an advance likely to improve structural materials for automobiles, airplanes and other applications that require lightweight and strong materials.

The results, published in the journal Advanced Functional Materials, show promise for making products that are stronger and more affordable, opening new options for U.S. manufacturers to use in applications such as energy and national security.

“The challenge of improving adhesion between carbon fibers and the that surrounds them has been a concern in industry for some time, and a lot of research has gone into different approaches,” said Sumit Gupta, the ORNL researcher who led the project. “What we found is that a hybrid technique using to create chemical and mechanical bonding yields excellent results.”

SwRI’s H2-ICE consortium launches second phase, H2-ICE2

March 25, 2025 (follow up)— Southwest Research Institute (SwRI) has launched the newest iteration of its industry-supported Hydrogen Internal Combustion Engine consortium, H2-ICE2.

In 2024, SwRI’s H2-ICE consortium completed construction of a Class 8, heavy-duty hydrogen-powered vehicle, following 18 months of targeted development. The demonstration vehicle achieves ultra-low nitrogen oxide and carbon dioxide emissions without sacrificing commercial viability. The consortium’s next iteration — “H2-ICE2” — will build on its prior success by enhancing and refining the vehicle’s overall performance and efficiency.

SwRI consortium will focus on enhancing H2-ICE-powered vehicle performance, efficiency.

Universal framework enables custom 3D point spread functions for advanced imaging

Engineers at the UCLA Samueli School of Engineering have introduced a universal framework for point spread function (PSF) engineering, enabling the synthesis of arbitrary, spatially varying 3D PSFs using diffractive optical processors. The research is published in the journal Light: Science & Applications.

This framework allows for advanced imaging capabilities—such as snapshot 3D —without the need for spectral filters, axial scanning, or digital reconstruction.

PSF engineering plays a significant role in modern microscopy, spectroscopy and computational imaging. Conventional techniques typically employ phase masks at the pupil plane, which constrain the complexity and mathematical representation of the achievable PSF structures.

World’s first non-silicon 2D computer developed

Silicon is king in the semiconductor technology that underpins smartphones, computers, electric vehicles and more, but its crown may be slipping, according to a team led by researchers at Penn State.

In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike , to develop a computer capable of simple operations.

The development, published in Nature, represents a major leap toward the realization of thinner, faster and more energy-efficient electronics, the researchers said.
