  • Atom-thick CCD could capture images
    An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.

  • A 'GPS' for molecules
    In everyday life, the global positioning system can be employed to reliably determine the momentary location of one en route to the desired destination. Scientists have now developed a molecular 'GPS' with which the whereabouts of metal ions in enzymes can be reliably determined. Such ions play important roles in all corners of metabolism and synthesis for biological products.

  • Improving rechargeable batteries by focusing on graphene oxide paper
    An engineering team has discovered some of graphene oxide's important properties that can improve sodium- and lithium-ion flexible batteries.

  • Glimpsing pathway of sunlight to electricity
    Four pulses of laser light on nanoparticle photocells in a spectroscopy experiment has opened a window on how captured sunlight can be converted into electricity. The work, which potentially could inspire devices with improved efficiency in solar energy conversion, was performed on photocells that used lead-sulfide quantum dots as photoactive semiconductor material.

  • Instant-start computers possible with new breakthrough
    If data could be encoded without current, it would require much less energy and make things like low-power, instant-on computing a ubiquitous reality. Scientists have made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.

  • Computational clues into the structure of a promising energy conversion catalyst
    Researchers at Princeton University have reported new insights into the structure of an active component of the nickel oxide catalyst, a promising catalyst for water splitting to produce hydrogen fuel.

  • Study fuels hope for natural gas cars: Metal organic framework candidates for methane storage identified
    Cars that run on natural gas are touted as efficient and environmentally friendly, but getting enough gas onboard to make them practical is a hurdle. A new study promises to help. Researchers have calculated the best candidates among possible metal organic frameworks to store natural gas for cars.

  • Crown ethers flatten in graphene for strong, specific binding
    Scientists have discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific electrostatic binding of crown ethers may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.

  • Choreography of an electron pair
    The motion of the two electrons in the helium atom can be imaged and controlled with attosecond-timed laser flashes.

  • New conversion process turns biomass 'waste' into lucrative chemical products
    A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.
