Ferroelectric localized field enhanced nanowire photodetectors

Researchers have designed a high-performance nanowire photodetector with side-gated structure by combining ferroelectric materials and nanowires, and the as-fabricated device can be employed to reduce the dark current and increase the sensitivity of the photodetectors.

Improving CD-AFM measurements from the tip down

Researchers have created reference samples that allow tip calibration with an uncertainty of less than 1 nm.

Heat and light get larger at the nanoscale

Scientists demonstrate a strong, non-contact heat transfer channel using light with performances that could lead to high efficiency electricity generation.

New use for X-rays: A radar gun for unruly atoms

Using coherent X-rays, a new technique has been discovered for sensing motion and velocity of small groups of atoms. This advance gives an unprecedented, nanoscale view of disordered objects as they are being created - like the thin films used to make solar cells and LCD screens.

Flat boron is a superconductor

Scientists have determined that two-dimensional boron is a natural low-temperature superconductor. In fact, it may be the only 2-D material with such potential.

Illuminating the inner 'machines' that give bacteria an energy boost

Researchers have tracked how microscopic organisms called cyanobacteria make use of internal protein 'machines' to boost their ability to convert carbon dioxide into sugar during photosynthesis.

New potent nanodrug to combat antibiotic-resistant infections

Novel approach includes noninvasive light activation of gold nanoconstructs to kill antibiotic-resistant bacteria.

Scientists divide magnetic vortices into collectivists and individualists

In manganese monosilicide, microscopic magnetic vortices ?- skyrmions - may behave as 'collectivists' or 'individuals', i.e. they are able to create a single structure, or they can also split up individually. Studying the behaviour of skyrmions will help to create unique quantum devices based on new physical principles.

Mechanical engineer builds 'ready-to-go' battery electrode with glass-ceramic

Researchers have developed a paperlike battery electrode using silicon oxycarbide glass and graphene.

Nanostructures made from DNA: Daisy chain rotaxanes as molecular bearings

Scientists have used DNA molecules to make a nanoscale component that makes it possible for two individual parts to move relative to each other.

Broadening the bilayer

Researchers use Titan to understand new theories on the organization of human and animal cellular membranes.
