Nanotechweb.org: best of 2013
This year, we've taken a month by month look across our Tech Update and Lab Talk channels to bring you our highlights from 2013. A wave of research on 2D materials is building on graphene's success in the lab, with other substances such as dichalcogenides joining the party. To discover our pick of the last 12 months, read on…
Flexible TEG breaks new power record
Energy harvested is enough to run ultra low-power CMOS circuitry in sensors, including some in vivo biomedical devices.
Natural metamaterial looks cooler when heated
Thin-film coating appears to hide its own temperature from thermal cameras.
MRI goes nanoscale
University of Illinois at Urbana-Champaign team performs magnetic resonance imaging (MRI) at spatial resolutions of just 10 nm, and is keen to develop the technology to explore virus particles in 3D.
Plasma reduction enables nanoscale platinum printing
Versatile printing strategy suits a wide range of conductive, insulating, hard or soft materials, and is being explored as a potential cell stimulation platform for bionic devices.
Nanoarray patch takes your temperature to millikelvin precision Team now working on making the devices completely wireless.
Ultrathin solar cell is efficient and easy to make
Promising results from a very straightforward layer-by-layer structure deposited by simple evaporation and solution processing techniques.
Piezophototronics makes highly sensitive skin-like sensor
Architecture could improve human prosthetics.
Strained WS2 nanosheets boost hydrogen production
Structure provides route to more affordable catalysts.
Terahertz emitters adapted for excitation at telecoms wavelengths (1.55 µm)
Large-area interdigitated design coupled to fibre laser as a step towards more affordable terahertz time-domain spectroscopy systems.
Nanoparticles control blood vessel growth
Peptide-coated gold nanoparticles can be used to deliberately activate or inhibit the growth of blood vessels. Discovery could be used to promote wound healing or slow down tumour growth, for example.
TMDC "wallpaper" produces electricity
High-tech sandwich could be a "game changer" in the solar energy sector.
CMOS chip transformed into nanopore sensor
Integrated approach has highly-compact and massively parallel biosenors in its sights.
Nanoparticles slow down cancer cells
Finding points towards therapeutic uses.
First light for MoS2
Result shows that light sources and photonic elements can be built from the 2D semiconductor.
Simple high-performance nanotube-based WORM memories
Low-cost devices change their conductance by five or six orders of magnitude when a voltage pulse is applied and could be used in electronic id cards.
CNT arrays make record-breaking transistors
IBM team describes scalable approach to fabricating dense, aligned arrays of electronically pure nanotubes.
Cladded quantum dots make better solar cells
UCLA group has come up with a new and simple way to control the optical properties of buried indium arsenide quantum dots, and is now busy applying the technique to prototype devices.
