Graphene laminate coatings can improve the thermal conductivity of plastic materials by up to 600 times. This new result, from an international team of researchers led by Alexander Balandin and Konstantin Novoselov, could substantially increase the potential range of practical applications for plastics, allowing them to be used in areas not possible until now – like […]
Thanks to a nanothermodynamic model, researchers at the University of Texas at San Antonio led by Miguel José-Yacaman have succeeded in predicting the phase diagram of nanoscale “Tumbaga” – a gold-copper alloy that was very popular in pre-Columbian times – and have thus discovered why it looks so much like pure gold. Although still used […]
A new way to stretch single-crystal silicon (which is a rigid, brittle, material) to 10 times its original length without using a polymer support has been developed by researchers at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. The feat will be an important step towards making stretchable and foldable electronics and […]

Rare-earth oxide (REO) nanoparticles interfere with a mechanism called autophagic flux in biological cells
Electrochromic devices, which allow the transmittance of light to be adjusted by applying a voltage, sound like a strong competitor to liquid crystal displays. Yet despite their proposed advantages of low cost and mechanical flexibility, fragile materials and material mismatches with the electrodes have so far hindered the performance of these newcomers in display technology. […]
A new way to make graphene oxide-based aerogels containing highly crystalline graphene sheets has been developed by researchers in California. The aerogels – which might find use in catalysts, energy-storage devices, sensors, composites and even in desalination technologies – are much better than previously made foams that were of a much poorer quality…… http://nanotechweb.org/cws/article/tech/58959 Graphene […]
Nanostructured boron nitride (BN) is a technologically important material thanks to its excellent mechanical and thermal properties. It could be ideal for use in a variety of electronics and optoelectronics applications and as a good support material for graphene devices because the two materials have very similar lattice constants. However, BN is notoriously difficult to […]
Researchers at the University of California at Berkeley and the Lawrence Berkeley National Lab have designed the first low-noise, high-gain, broad-bandwidth Josephson travelling wave parametric amplifier using a technique called “resonant phase matching”. The scheme boosts the gain in the amplifier by more than 10 dB compared with previous such devices, bringing its value up to […]
Invitation to attend: Special Talk on “Nanoporous Catalysts for Cleaner Energy and Environment”
The 2014 Nobel Prize in Physics 2014 has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for their development of blue LEDs. The prize is worth SEK 8m (£690,000) and will be shared by the three winners who will receive their medals at a ceremony in Stockholm on 10 December………. http://nanotechweb.org/cws/article/tech/58844 Bright […]
Thin film interference effects can persist on both smooth and very rough substrates. This surprising new result, from researchers at Harvard University in the US, means that films exhibiting these effects (which change colour depending on their thickness) might be used in flexible electronics and optoelectronics devices, as well as to make ultra-lightweight coatings….. http://nanotechweb.org/cws/article/tech/58852 […]
Researchers at the King Abdullah University of Science and Technology in Saudi Arabia are the first to have studied how flexible Fin field effect transistors (FinFETs) behave at high temperatures. FinFETs are the semiconductor industry’s most advanced transistors so it is important to understand how the flexible versions of these devices behave under different operating […]
Researchers at the University of Cambridge in the UK say that they have observed “spin-triplet” excitons (electron-hole pairs) “hopping” from an organic semiconductor, pentacene, onto an inorganic semiconductor. The mechanism might be used to help reduce unwanted heat loss in photovoltaic devices – something that ultimately limits their performance….. http://nanotechweb.org/cws/article/tech/58875 Pentacene absorbing light
The 2014 Nobel Prize for Chemistry has gone to Eric Betzig, Stefan Hell and William Moerner for developing super-resolution microscopy techniques based on the fluorescence of molecules. The prize is worth SEK 8m (£690,000) and will be shared by the three winners, who will receive their medals at a ceremony in Stockholm on 10 December….. […]
A workshop on “The Development of Nanostructure Lipid Carrier from Sugarcane Wax for lipstick and nail polisher” was jointly hosted by NSTDA, NRCT, TRF, and NANOTEC at Sofitel Hotel in Bangkok, Thailand
Researchers in France have developed a new way to create cylindrical vector (CV) beams by electrically exciting a “plasmonic lens” with low-energy, tunnel electrons
Studying interactions between individual micromotors can help in understanding the fundamental principles of matter in dynamic steady states far from equilibrium.
Nanophotonic resonators attract interest for a range of potential applications and fundamental studies.
