To "turn" sunlight into chemical fuels, scientists are investigating a junction inside designer solar cells. The connection is difficult to probe. Scientists devised a probe and found that the junction promotes the release of electrons and suppresses unwanted reactions.
Some efforts to improve solar panel efficiency by focusing on surface plasmons, light waves trapped on a metal surface, but the processes didn't prove to be highly efficient. Researchers found that plasmon induced hot electron transfer could take a more efficient route.
Led by Pacific Northwest National Laboratory, scientists conducted a collaborative study that answered foundational questions about how nature influences the composition of aerosols. The team's findings could help avoid unintended consequences in both regulations and remediation.
A new family of nature-inspired materials that, when placed in water, spontaneously assemble into nanotubes is the latest in the effort to use synthetic polymers to precisely build durable nanotubes that approach the complexity and function of nature's proteins.

State-of-the-art weather radars were installed at Atmospheric Radiation Measurement (ARM) Climate Research Facility sites.
Physicists and engineers demonstrated that it is possible to use liquid helium to apply an electric field several times larger than that used in previous neutron electric dipole moment experiments, which provides insights into the nature of the universe.
Scientists built enzymes that efficiently produce hydrogen, one half of the "holy grail" of splitting water to make hydrogen to fuel cars.
Thanks to a new technique, scientists can analyze proteins collected from an intact microbial community, gaining insights into how the broader system works.
A new protective barrier can prevent lithium-metal batteries from failing. The barrier allows the electrode to work at room temperature and hampers the detrimental formation of dendrites. Scientists made this film.
Scientists discovered a self-assembly mechanism that surprisingly drives negatively charged molecules to clump together to form islands when graphene is supported by an electrical insulator.
Scientists modeled runoff using two widely adopted methods. They found that the modeling choices result in differences that ultimately swing results in carbon cycle simulations--by as much as 20%.
Scientists changed our understanding of metal-organic frameworks. They uprooted the belief that these frameworks must be made from rigid starting materials.
Converting light from one wavelength to a shorter wavelength is typically inefficient. To tackle that inefficiency, a team built a structure with metallic cavities that improves the light conversion efficiency by orders of magnitude.
Scientists stretched a crystal lattice in just one dimension, allowing them to tune the structure's electronic and magnetic properties.
To create the next generation of solar panels, scientists must model how complex interactions occur. Modeling across different scales provides needed insights. In a review article, scientists assessed the state of the art for calculations used to model electronic states in very thin films.
More efficient solar cells will likely be based on a family of materials known as hybrid perovskites. Scientists identified how to control different properties and stability in these solar cell materials using lead-free preparation.
Molecular Foundry scientists developed a new imaging technique that greatly improves images of light elements by fewer electrons in electron microscopy.
For the first time, scientists captured high-resolution 3D images from individual double-helix DNA segments attached at either end to gold nanoparticles, potentially valuable information about disease-relevant proteins and DNA assembly.
Researchers discovered a way to significantly improve graphene's performance in detecting noxious gases. They peppered high-quality sheets with boron impurities.
If biochemists had access to a quantum computer, they could perfectly simulate the properties of new molecules to develop drugs in ways that would take today's fastest computers decades. A new device takes us closer to providing such a computer.
Using resources at the Center for Functional Nanomaterials, scientists tailored extremely small wires that carry light and electrons. These new structures could open up a potential path to smaller, lighter, or more efficient devices.
