Researchers watched nanoscale semiconductor crystals expand and shrink in response to powerful pulses of laser light. This ultrafast 'breathing' provides new insight about how such tiny structures change shape as they start to melt - information that can help guide researchers in tailoring their use for a range of applications.
Creating large amounts of polymer nanofibers dispersed in liquid is a challenge that has vexed researchers for years. But engineers have now reported a method that can produce unprecedented amounts of polymer nanofibers, which have potential applications in filtration, batteries and cell scaffolding.
Nanoparticle electrodes in lithium-ion batteries have both near-surface and interior contributions to their redox capacity, each with distinct rate capabilities. Using combined electron microscopy, synchrotron X-ray methods and ab initio calculations, scientists have investigated the lithiation pathways that occur in NiO electrodes.
Scientists report the first durable, flexible cloth that harnesses human motion to generate energy. It can also self-charge batteries or supercapacitors without an external power source and make new commercial and medical applications possible.
A new study finds that new optical materials could serve as the nuts and bolts of future ultra-high-speed optical computing components. These 'nonlinear metamaterials', which possess physical capabilities not found in nature, may be the building blocks that allow major companies like IBM and Intel to move from electronic to optical computing.
Time wise, the NANoREG project is now halfway. After setting the basic conditions for its R+D work, the project now focuses on the generation of reliable and comparable experimental data on the EHS aspects of the selected NANoREG nanomaterials.
Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell.
In a new approach to understand dynamic phase transitions, a joint experimental and theoretical effort was undertaken by a team of scientists, using a novel type of quantum matter in a so-called superradiant state.
Flexible optoelectronic devices that can be produced roll-to-roll are a highly promising path to cheaper devices such as solar cells and LED lighting panels. Scientists from TREASORES project present prototype flexible solar cell modules as well as novel silver-based transparent electrodes that outperform currently used materials.
As part of a U.S. Department of Energy effort to showcase new data-handling strategies, scientists from Brookhaven National Laboratory demonstrated two pilot projects for modeling and processing large-volume data sets at the SC14 (Supercomputing 2014) conference.
