A new way to make complex, layered semiconductors is like making rock candy: They assemble themselves from chemicals in water. The method will aid design and large-scale production of these materials.
After 20 years of trying, scientists doped a 1D copper oxide chain and found a surprisingly strong attraction between electrons that may factor into the material’s superconducting powers.
Anchoring individual iridium atoms on the surface of a catalyst made them a lot better at splitting water – a reaction that’s been a bottleneck in making sustainable energy production more competitive.
Are new nickelate superconductors close kin to the original high-temperature superconductors, the cuprates? The first study of their magnetic properties says the answer is yes. Scientists from SLAC, Stanford and Diamond Light Source found important similarities but also subtle differences between the two.
SLAC and Stanford scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. The results could suggest a fix.
Transitioning to a hydrogen economy will require massive production of cheap, clean hydrogen gas for fuel and chemical feedstocks. New tools allow scientists to zoom in on a catalytic reaction that’s been a bottleneck in efforts to generate hydrogen from water more efficiently.
According to the World Health Organization, one in six worldwide deaths are attributed to cancer, but not due to initial malignant tumors. They were caused by the spread of cancer cells to surrounding tissues, which consist largely of collagen. That was the focus of a recent study by Stanford University and Purdue University researchers.
Scientists are hoping advances in cancer research could lead to a day when a patient’s own immune system could be used to fight and destroy a wide range of tumors. Cancer immunotherapy has some remarkable successes, but its effectiveness has been limited to a relatively small handful of cancers. In APL Bioengineering, researchers describe how advances in engineering models of tumors can greatly expand cancer immunotherapy’s effectiveness to a wider range of cancers.
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well within the reach of today’s manufacturing processes.
Polarons affect a material’s behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists have directly seen and measured their formation for the first time.
The first detailed images of coronavirus spikes in their natural state, while still attached to the virus and without using chemical fixatives that might distort their shape, provide quicker, more realistic snapshots of the infection apparatus.
Conservation of fish and other marine life migrating from warming ocean waters will be more effective and also protect commercial fisheries if plans are made now to cope with climate change, according to a Rutgers-led study in the journal Science Advances.
The NIH is establishing a national service center at the SLAC and Stanford where biomedical researchers can learn how to prepare extremely thin specimens that are frozen into a glassy state for cryogenic electron tomography (cryo-ET), a powerful tool for directly visualizing cellular components in 3D.
This new technology addresses two major goals of battery research: extending the driving range of electric vehicles and reducing the danger that laptops, cell phones and other devices will burst into flames.
Researchers from four institutions will create a “startup blueprint” that cities can use to implement SARS-CoV-2 surveillance at their area’s wastewater treatment plants. Funded by the Sloan Foundation, the action plan they develop could be used to monitor COVID-19 and other pathogens.
A study identified which pairs of atoms in a catalyst nanoparticle are most active in a reaction that breaks down a harmful exhaust gas in catalytic converters. The results are a step toward engineering cheaper, more efficient catalysts.
Developed in the lab of Stanford University Nobelist W.E. Moerner, the technique combines cryoelectron tomography and low temperature single-molecule microscopy. It has potential to answer fundamental questions about the molecular machinery of viruses, parasites, and processes like photosynthesis.
Scientists at Berkeley Lab and Stanford have joined forces to aim a gene-targeting, antiviral agent called PAC-MAN against COVID-19.
University of Utah biomedical engineering assistant professor Jan Kubanek has discovered that sound waves of high frequency (ultrasound) can be emitted into a patient’s brain to alter his or her state. It’s a non-invasive treatment that doesn’t involve medications or surgery and has a unique potential to treat mental disorders including depression and anxiety and neurological disorders such as chronic pain and epilepsy.
The American Institute of Physics, celebrating the 30th anniversary of the launch of the NASA/ESA Hubble Space Telescope, is delighted to host a virtual presentation by Stanford University’s Elizabeth Kessler in an upcoming Lyne Starling Trimble Science Heritage Public Lecture. The lecture series is presented by AIP and features science historians and writers who study the role of science and technology in modern society and culture. “Hubble Space Telescope Images and the Astronomical Sublime” will be hosted virtually, Thursday, May 7 at 3:30 p.m. Eastern (U.S.).
The average number of unsafely hot summer days could double by 2050 and triple by 2100 in U.S. counties where agricultural crops are grown. The study also looks at different strategies the industry could adopt to protect workers’ health.
Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad range of materials for use in things like sensors and detectors.
Researchers observed atomic nuclei moving over distances of less than an angstrom in less than a trillionth of a second — a level of resolution that can only be achieved with an X-ray free-electron laser.
Stanford University researchers created an inverse design codebase called SPINS that can help researchers explore different design methodologies to find fabricable optical and nanophotonic structures. In the journal Applied Physics Reviews, Logan Su and colleagues review inverse design’s potential for optical and nanophotonic structures, as well as present and explain how to use their own inverse design codebase.
A review of recent work in biophysics highlights efforts in cellular engineering, ranging from proteins to cellular components to tissues grown on next-generation chips. Author Ngan Huang said the fast pace of development prompted her and her colleagues to take stock of promising areas in the field as well as hurdles researchers can expect in coming years. They discuss their work in this week’s APL Bioengineering.
A team of scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University has gained insight into how electric fields affect the way energy from light drives molecular motion and transformation in a protein commonly used in biological imaging.
Many microbes wear beautifully patterned crystalline shells. Now scientists have zoomed in on the very first step in microbial shell-building: nucleation, where squiggly proteins crystallize into sturdy building blocks. The results help explain how the shells assemble themselves so quickly.
