Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

Neuron and synapse-mimetic spintronics devices developed

A research group from Tohoku University has developed spintronics devices which are promising for future energy-efficient and adoptive computing systems, as they behave like neurons and synapses in the human brain.

Light from exotic particle states

A new type of light-emitting diode has been developed at TU Wien. Light is produced from the radiative decay of exciton complexes in layers of just a few atoms thickness.

Some piezoelectric materials may be 'fakes'

Piezoresponse force microscopy (PFM) is the most widespread technique for characterising piezoelectric properties at the nanoscale, i.e., for determining the ability of some materials to generate electricity when subjected ...

Water that never freezes

Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels.

A compass pointing west

Researchers at the Paul Scherrer Institute PSI and ETH Zurich have discovered a special phenomenon of magnetism in the nano range. It enables magnets to be assembled in unusual configurations. This could be used to build ...

New 3-D printing approach makes cell-scale lattice structures

A new way of making scaffolding for biological cultures could make it possible to grow cells that are highly uniform in shape and size, and potentially with certain functions. The new approach uses an extremely fine-scale ...

Chemicals induce dipoles to damp plasmons

The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why.

One transistor for all purposes

In mobiles, fridges, planes – transistors are everywhere. But they often operate only within a restricted current range. LMU physicists have now developed an organic transistor that functions perfectly under both low and ...

Molecular motors run in unison in a metal-organic framework

For molecular motors to be exploited effectively, they need to be able to operate in unison. However, integrating billions of these nanometre-sized motors into a single system and getting them to operate in unison has proved ...

Motion control at the nanoscale

NUS Physicists have designed a bipedal nanowalker that can change its walking manner and direction by adjusting the length of its stride. Deoxyribonucleic acid (DNA)-based nanowalkers are a class of molecular motors which ...
