Photonic crystals: how defects lead to a prison for light

Researchers demonstrate how defects in a 3D crystal can create photonic bandgap cavities for light that may be useful for lasing, LEDS, information storage and sensitive pharmaceutical sensors

Sound control of nanorod ‘molecules’

The assembly and disassembly of nanorods propelled by ultrasound provides an insight into biological motors.

Excited “plasmonic lens” converts tunnel electrons into CV beam

A new way to create cylindrical vector beams could benefit applications in quantum optics, microscopy and data storage and communications.

HHG sheds new light on charge carrier dynamics

New experiments could help us better understand how electrons and holes behave at material interfaces – important for a number of energy-based technologies.

Magnetic nanoemulsion measures blood glucose

A new type of glucometer is label free and works by simply changing colour.

Gold NPs kill MDR bacteria

Functionalized gold nanoparticles can combat multi-drug-resistant pathogenic bacteria – including both Gram-negative and Gram-positive strains.

Graphene almost there for silicon wafer-scale standard

A new way to grow high-quality samples of the carbon sheet measuring between 100 and 300 nm across has been developed by researchers in the US and UK.

Graphene provides ultrasensitive generic biodetection

Nano- and picomolar detection of a range of biomarkers has been demonstrated using functionalized graphene.

Nanoporous hydroxide makes good supercapacitor

Thin film has a high capacitance and promising energy and power densities, and so could be ideal for practical devices.

Nanotubes couple up

First observation of strong inter-tube coupling in “incommensurate” DWCNTS could help in the development of better electronics devices from these nanomaterials.

New plasmonic nanolaser is cavity-free

Proposed device could improve optical telecommunications.

Ionic crystals go 1D

Researchers in Japan have made the first truly one-dimensional diatomic chains inside CNTs.

Plasmonic nanoclusters could detect single molecules

Oligomers interact with light more strongly than isolated, uncoupled nanoparticles thanks to multiple plasmonic “hot spots” created in each cluster.

FinFETs go flexible

New soft-etching technique could allow for new applications in consumer electronics, such as in the emerging field of the “Internet of Things”.

Nanostructure toughens lightweight ceramics

Structuring a ceramic metamaterial makes it not only strong and light, but also robust enough to recover its original shape when deformed.

Graphene’s photothermoelectric effect for THz detection

New device is as sensitive as the best THz radiation detectors but it is a million times faster.

Tunnelling electrons make new type of transistor

Device consists of an ultrathin barrier of hexagonal boron nitride sandwiched between two graphene electrodes.

CdTe ink makes high-efficiency solar cell

Devices made using cadmium telluride layers have a sunlight-to-power conversion of efficiency of more than 10%.

Graphene drum could make good motion sensor and memory chip

Kavli researchers couple carbon resonator to a superconducting microwave cavity for the first time.

Watching nucleation from start to finish

Transmission electron microscopy obervations reveal the formation of the mineral calcium carbonate from start to finish.
