two-dimensional boron has potential advantages over graphene

Scientists at Rice University used the notion of Swiss cheese to analyze the possible configurations of two-dimensional sheets of boron. They found that these 2-D sheets of boron, when rolled into tubes, could have a distinct advantage over carbon nanotubes since boron nanotubes are always metallic, avoiding the challenge of selecting a particular symmetry. When [...]

transparent memory chip

As technology moves forward, things get smaller, faster and now possibly transparent. A team of scientists have developed transparent, flexible memory chips that may one day replace flash drives and other personal data storage devices. New memory chips that are transparent, flexible enough to be folded like a sheet of paper, shrug off 1,000-degree Fahrenheit [...]

Molecular Graphene

The first ever electrons with tunable properties were observed at the SLAC National Accelerator Laboratory. By repositioning the carbon monoxide molecules that were placed on a perfectly smooth copper surface, the team was able to tune the electrons’ properties. Menlo Park, California — Researchers from Stanford University and the U.S. Department of Energy’s SLAC National [...]

Graphene

It has been extremely difficult to create graphene-based devices that reliably operate at room temperature and pressure, until now. By submerging sheets of graphene in electrically neutral liquids, the physicists at Vanderbilt believe they have found the source of the interference inhibiting the rapid flow of electrons through graphene-based devices and have achieved record-level mobility.

Photodetectors made from graphene

Physicists at the Technische Universitaet Muenchen developed a method to increase the time resolution of photocurrent measurements in graphene into the picosecond range. While conducting their research, they were able to monitor precisely how the photocurrent in the graphene is generated and found evidence that graphene emits radiation in the terahertz range when optically stimulated.

3-D Image of an Individual Protein

Researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) produced the first ever 3-D images of an individual protein. Using a technique they call “individual-particle electron tomography,” or IPET, these researchers were able to capture images of a single IgG antibody and apolipoprotein A-1 (ApoA-1.) When Gang Ren whirls the [...]
