Nanoindentation technique measures 2D elastic modulus

TMDCs and their heterostructures could be ideal for making flexible optoelectronics and photonics devices.

Polymer nanospheres make good OPVs

New water-based fabrication process for organic photovoltaics allows researchers to control component assembly at different length scales for the first time.

New calculations help figure out single-molecule junctions

Qualitatively and quantitatively correct calculations of porphyrin single-molecule junction conductances are achieved for the first time, explaining the sensitivity of the conductance to the metal centre.

Multilayer silicene proves stable in air

Silicene has been shown to be stable in air, opening the way to further studies of the new material’s properties and potential technologies that might exploit them.

Triptolide nanogel treats liver cancer

Coated version of naturally occurring antitumor compound appears to be more effective against hepatocellular carcinoma than conventional therapies.

Polychiral CNTs make better solar cells

New devices are nearly two times better at converting sunlight into power.

Nanoparticles tackle cancer with heat and 'suicide genes'

Magnetic nanoparticles hunt down cancerous tissue in the body and deliver "suicide genes" to destroy the cells.

Perovskites make bright LEDs of many colours

Light-emitting devices could be ideal for colour displays and lighting, and in optical communication applications.

Molecular seeds sprout identical carbon nanotubes

The first effective technique for growing a batch of single-walled carbon nanotubes (SWCNTs) that all have the same molecular structure has been developed by scientists in Switzerland.

Shuttle mechanism helps nanorods produce more hydrogen

Redox reduction experiments could help in the development of better photoactive materials that harness solar energy to produce fuels in a process called water splitting.

Electric field enhances solar cell

Low-cost phosphide-graphene device lacks a junction and does not need to be doped either

Opening a new near-infrared window for imaging the brain

First non-invasive technique could monitor vascular blood flow and structure in real time and potentially help stroke patients and those with Alzheimer’s and brain tumours

Thermal emitters speed up

New infrared device is 10 000 faster than previous ones

Silicon nanorods bend light in new directions

Ultrathin coatings could replace bulky optical components

How to control superfast surface plasmons

Experiments on InAs will be important for making optically controlled plasmonic circuits for use in a wide range of applications, from nanophotonics to biosensing.

Light 'needles' thread plasmonic nanoparticles together

New nano-welding technique can be used to assemble nanostructures like chiral metamaterials from the bottom up for applications in molecular sensing and to make "cloaking devices".

Magnetite self-assembly: competition yields surprises

Nanocrystals of magnetite self-assemble in the presence of competing van der Waals and magnetic forces into previously unseen helical structures.

Lasing plasmon nanocavity detects deadly explosives

New device might be used in applications such as security screening at airports and in biosensing.

Fluorophore positioning goes viral

Researchers combine viral and DNA self-assembly methods to control the positioning of almost 200 fluorophores within nanometers of a gold nanoparticle.

Hydrogen spills over large distances

New work will be important for better understanding how catalysts work on the nanoscale and might even help in the production of next-generation biofuels for transport.
