Printed, flexible and rechargeable battery can power wearable sensors (w/video)

Nanoengineers have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics.

'Bobcat nanowagon' is a first step toward creating a new academic field

From nanocars to developing a controlled transport system at the molecular scale.

Paper test strip could help heart failure patients monitor their condition at home

Researchers developed a paper-based test that requires only a small blood sample of 10 microliters. A blue dot glows on the strip if ST2 is present in the sample, and a green dot glows if it contains BNP.

Experiment shows that optical properties of 3D graphene are tuneable

An international research team has for the first time investigated the optical properties of three-dimensional nanoporous graphene. The experiments show that the plasmonic excitations in this new material can be precisely controlled by the pore size and by introducing atomic impurities.

Neutrons provide the first nanoscale look at a living cell membrane (w/video)

A research team has performed the first-ever direct nanoscale examination of a living cell membrane. In doing so, it also resolved a long-standing debate by identifying tiny groupings of lipid molecules that are likely key to the cell's functioning.

Precise insight into the depths of cells

Is it possible to watch at the level of single cells how fish embryos become trout, carp or salmon? Researchers have successfully combined two very advanced fluorescence microscopy techniques. The new high-resolution light microscope permits fascinating insights into a cell?s interior.

Feather-light metal cathodes for stable lithium-oxygen batteries

Researchers report a new type of cathode, which could make lithium-oxygen batteries a practical option.

Explainer: what is nanomedicine and how can it improve childhood cancer treatment?

Nanomedicine has great potential to safely treat children's cancer. However, it is currently stymied by too little research. About two-thirds of research attention in nanomedicine therapeutics, of more 250 nanomedicine products, is focused on cancer. Yet this isn't translating into new cancer treatments for children coming to market.

Measured for the first time: direction of light waves changed by quantum effect

After much speculation spanning a long period of time, one variant of the magneto-optical effect has now been demonstrated at for the first time.

Special X-ray technique allows scientists to see atomic scale 3-D deformations

In a new study, researchers used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects.

New theory predicts wetted area of droplets colliding with flat surface

Researchers have succeeded in deriving a theoretical formula that quantitatively predicts the wetting and spreading behavior of droplets that collide with the flat surface of a solid material.

Water is surprisingly ordered on the nanoscale

Scientists discovered that molecules on the surface of the drops were much more ordered than expected. Their surprising results pave the way to a better understanding of atmospheric, biological and geological processes.

A fresh look inside the protein nanomachines

A new physical model of protein evolution suggests a mechanical basis for the DNA map of functional proteins.

One-dimensional crystals for low-temperature thermoelectric cooling

Researchers report high thermoelectric powers in one-dimensional crystals for practical low-temperature cooling.

Nanoalloys ten times as effective as pure platinum in fuel cells

A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars.
