Nanoscale Infrared Study of Meteorite Mineralogy
Using a nanoscale infrared probe, researchers found that the minerals in a meteorite—an artifact representing the solar system’s past—were altered by water on very fine spatial scales. The work sheds light on conditions in the early solar system and lays groundwork for analyzing asteroid samples to be returned to Earth by NASA in 2023. Read more »
A Topological-Insulator Sandwich for Efficient Microelectronics
Researchers synthesized a topological insulator between two ferromagnetic layers and found that it is electronically characterized by a large magnetic band gap. The results open a new path toward lossless charge transport and perfect spin polarization, which could lead to the development of ultralow-energy electronics and spintronics. Read more »
Decoupling the metal–insulator transition temperature and hysteresis of VO2 using Ge alloying and oxygen vacancies
The VO2 metal–insulator transition underpins applications in thermochromics, neuromorphic computing, and infrared vision. Ge alloying is shown to expand the stability of the monoclinic phase to higher temperatures, and by suppressing the propensity for oxygen vacancy formation, renders the hysteresis of the transition exquisitely sensitive to oxygen stoichiometry.

Removing Nitrogen from Wastewater using Horizontal Levees
Treated municipal wastewater often contains nitrogen, which has been linked to algal blooms that can devastate coastal ecosystems. In a recent study, researchers characterized the primary nitrogen-removal pathways in a horizontal levee, an engineered subsurface water-treatment system consisting of a gently sloping strip of land adjacent to storm-control levees.

Pushing the Boundaries of Moore’s Law: How Can Extreme UV Light Produce Tiny Microchips?
For the past 25 years, scientists and engineers from the Center for X-Ray Optics (CXRO) have worked to develop EUV lithography, a technique that enables microchip circuits and transistors that are tens of thousands of times thinner than a strand of human hair. Patrick Naulleau, a CXRO scientist who helped develop EUV lithography, shares his perspective in this Q&A. Read more »

Bacterial Enzyme Produces Biodegradable Polymer
Researchers discovered a bacterial enzyme that synthesizes a biopolymer whose repeating units are linked together in way that had not been previously observed. The new polymer is biodegradable and may be biocompatible, with potential for applications ranging from medical therapeutics to eco-friendly plastic alternatives. Read more »
