Modern electron microscopes can capture incredibly detailed images of materials down to the atomic level, but they require a skilled operator and can only focus on very small areas at a time. Now, researchers from the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have created a n automated workflow that overcomes these limitations by allowing large amounts of data to be collected over wide areas without human intervention and then quickly transferred to supercomputers for real-time processing. Much of the work was done at The Molecular Foundry and the National Energy Research Scientific Computing Center, two DOE Office of Science user facilities at Berkeley Lab.

Polymer-coated nanoparticles loaded with therapeutic drugs show significant promise for cancer treatment. Over the past decade, researchers at the Massachusetts Institute of Technology (MIT) have created a variety of these nanoparticles using a technique called layer-by-layer assembly. To help move these nanoparticles closer to human use, the researchers have now come up with a manufacturing technique that allows them to generate larger quantities of the nanoparticles in a fraction of the time. The researchers have filed for a patent on the technology and are now working with MIT’s Deshpande Center for Technological Innovation in hopes of potentially forming a company to commercialize the technology.

Researchers from Northwestern University and the University of California, San Diego, have developed new technology that could lead to the creation of a rapid point-of-care test for HIV infection. The technology uses a nanomechanical platform and tiny cantilevers to detect multiple HIV antigens at high sensitivity in a matter of minutes. Built into a solar-powered device, this technology could be taken to hard-to-reach parts of the world, where early detection remains a challenge to deliver fast interventions to vulnerable populations without waiting for lab results.

When materials are created on a nanometer scale, even the thermal energy present at room temperature can cause structural ripples. How these ripples affect the mechanical properties of these thin materials can limit their use in electronics and other key systems. Now, using a semiconductor manufacturing process, researchers from Binghamton University, Harvard University, Princeton University, Penn State, and the U.S. Department of Energy’s Argonne National Laboratory have created alumina structures that are 28 nanometers thick on a silicon wafer with thermal-like static ripples, and then tested these ripples with lasers to measure their behavior. The results match with theories proposed about such structural ripples.

An international team led by Rutgers University-New Brunswick researchers has merged two lab-synthesized two-dimensional materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing. One slice of the quantum structure is made of dysprosium titanate, an inorganic compound used in nuclear reactors, while the other is composed of pyrochlore iridate, a new magnetic semimetal. The specific electronic and magnetic properties of the material developed by the researchers can help in creating very unusual yet stable quantum states, which are essential for quantum computing.
