Carbon nanotube semiconductors are well-suited for photovoltaics
(Nanowerk News) Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) discovered single-walled carbon nanotube semiconductors could be favorable for photovoltaic systems because they can potentially convert sunlight to electricity or fuels without losing much energy.

Nanocrystal self-assembly sheds its secrets | MIT News
The secret to a long-hidden magic trick behind the self-assembly of nanocrystal structures is starting to be revealed.
The transformation of simple colloidal particles — bits of matter suspended in solution — into tightly packed, beautiful lace-like meshes, or superlattices, has puzzled researchers for decades. Pretty pictures in themselves, these tiny superlattices, also called quantum dots, are being used to create more vivid display screens as well as arrays of optical sensory devices. The ultimate potential of quantum dots to make any surface into a smart screen or energy source hinges, in part, on understanding how they form.

Scientists exploit nanotechnology approaches to speed up chemical reactions
Scientists exploit nanotechnology approaches to speed up chemical reactions
(Nanowerk News) Researchers at the University of Barcelona (UB) and two universities in Australia have introduced a new way of catalysing-speeding up- chemical reactions by applying an electric field between the reacting molecules. This opens the door for the fabrication of chemical compounds, used in pharmaceutical products and materials, in a fast and cheaper way.

Nanotubes and nanocrystals combine to produce green fuels - Materials Today
Chemists at the University of Texas at Arlington (UTA) have developed new high-performing materials that can use sunlight to split carbon dioxide and water into usable fuels like methanol and hydrogen gas. These ‘green fuels’ could be used to power cars and home appliances, or store energy in batteries.

PROVIDENCE, R.I. [Brown University] -- Imagine a hand-held environmental sensor that can instantly test water for lead, E. coli, and pesticides all at the same time, or a biosensor that can perform a complete blood workup from just a single drop. That's the promise of nanoscale plasmonic interferometry, a technique that combines nanotechnology with plasmonics--the interaction between electrons in a metal and light.

Graphenano and Grabat launch graphene-based batteries! | Graphene-Info
"The Spanish Graphenano recently introduced, together with its Chinese partner Chint, graphene polymer batteries that reportedly allow for a range of 800 kilometers in electric vehicles and can be charged in a few minutes. The batteries are meant for domestic use, in the automotive sector (both cars and bicycles), drones or even pacemakers. "

Un moyen facile de détecter la qualité de l'air
Un moyen facile de détecter la qualité de l'air
Pour améliorer la qualité de l'air à l'intérieur de bâtiments, l'une des étapes importantes consiste à trouver une méthode de mesure et de contrôle facile à appliquer. IAQSENSE (Nanotechnology based gas multispectral sensing system for environmental control and protection) est un projet sur trois ans financé par l'UE qui vise à trouver précisément cette méthode en développant de nouveaux systèmes de détection basés sur les nanotechnologies et destinés à contrôler la qualité de l'air intérieur (IAQ) dans des lieux fermés.

Carbon nanotubes bring a new touch to robotics - Materials Today
A skin-like polymeric material is using carbon nanotubes (CNTs) to bring a sense of touch to robotic and prosthetic devices. Developed by researchers at Stanford University and Xerox Palo Alto Research Center, the flexible, polymeric skin or ‘digital tactile system’ (DiTact) incorporates CNT pressure sensors and flexible organic printed circuits to mimic human response [Tee et al., Science 350 (2015) 313].

Graphene and metal nitrides improve the performance and stability of energy storage devices
Graphene and metal nitrides improve the performance and stability of energy storage devices
Supercapacitors can be charged and discharged tens of thousands of times, but their relatively low energy density compared to conventional batteries limits their application for energy storage. Now, A*STAR researchers have developed an 'asymmetric' supercapacitor based on metal nitrides and graphene that could be a viable energy storage solution.
