Physicists bind single-atom sheets with the same force geckos use to climb walls
Physicists at the University of Kansas have fabricated an innovative substance from two different atomic sheets that interlock much like Lego toy bricks. The researchers said the new material—made of a ...
Graphene / nanotube hybrid benefits flexible solar cells
(Phys.org) —Rice University scientists have invented a novel cathode that may make cheap, flexible dye-sensitized solar cells practical.
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria
Wriggle your toes in a marsh's mucky bottom sediment and you'll probably inhale a rotten egg smell, the distinctive odor of hydrogen sulfide gas. That's the biochemical signature of sulfur-using bacteria, ...
Researchers discover a way to tease oxygen molecules from carbon dioxide
Future flexible electronics based on carbon nanotubes: Improving nanotube transistor performance with fluoropolymers
Researchers from the University of Texas at Austin and Northwestern University have demonstrated a new method to improve the reliability and performance of transistors and circuits based on carbon nanotubes ...
Nanotubes help healing hearts keep the beat
(Phys.org) —Carbon nanotubes serve as bridges that allow electrical signals to pass unhindered through new pediatric heart-defect patches invented at Rice University and Texas Children's Hospital.
Smallest possible diamonds form ultra-thin nanothreads
For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest ...
A nanosized hydrogen generator
(Phys.org) —Researchers at the US Department of Energy's (DOE) Argonne National Laboratory have created a small scale "hydrogen generator" that uses light and a two-dimensional graphene platform to boost ...
Plant engineered for more efficient photosynthesis
(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.
Scientists refine formula for nanotube types
(Phys.org) —Many a great idea springs from talks over a cup of coffee. But it's rare and wonderful when a revelation comes from the cup itself.
Researchers' acid-free approach leads to strong conductive carbon threads
(Phys.org) —The very idea of fibers made of carbon nanotubes is neat, but Rice University scientists are making them neat—literally.
Chemists create 'assembly-line' for organic molecules
(Phys.org) —Scientists at the University of Bristol have developed a process where reagents are added to a growing carbon chain with extraordinary high fidelity and precise orientation, thereby controlling ...
Engineers advance understanding of graphene's friction properties
(Phys.org) —An interdisciplinary team of engineers from the University of Pennsylvania has made a discovery regarding the surface properties of graphene, the Nobel-prize winning material that consists of ...
