La entrada de Repsol en el accionariado de Nanogap, firmada el pasado mes de diciembre por un total de 1,8 millones de euros, lo que supone un 9% de su capital, refuerza la estrategia de la empresa gallega, que ha alcanzado ya las 83 patentes concedidas, según ha explicado en una entrevista concedida a EFEemprende la directora ejecutiva de Nanogap, Tatiana López del Río.
If you thought lithium-ion batteries catching fire were dangerous, how about a portable power source that actually relies on igniting its fuel from the get-go? That’s pretty much what a new battery alternative developed at MIT does.
A few years ago, researchers found that they could coat a long thin carbon nanotube—like a sheet of graphene wrapped into a tight cylinder—in combustible material. Letting it burn from one end, like a long wick or fuse, they discovered that the the system generated a tiny electrical current. The heat pulse pushes electrons along the tube, creating a current.
On a sunny day on the campus of the University of California, Berkeley, the peaceful rustling of eucalyptus trees belies the furious chemical activity happening inside every single leaf. Through photosynthesis, leaves use the energy in sunlight to turn water and carbon dioxide into substances that plants need, emitting only oxygen in the process. In a nearby lab, chemist Peidong Yang is building an artificial system that does the same, using arrays of nanowires coupled with engineered bacteria. If something like this is ever scaled up, it would churn out a better version of the fuels we use today—one that does not add to the total amount of carbon dioxide in the air.
El centro de investigación en NanocienciaCIC nanoGUNE, junto a otros promotores, ha creado su quinta empresa spin-off: Prospero Biosciences SL (Prospero). El objetivo de Prospero es valerse de las ventajas que ofrece la nanotecnología para desarrollar un innovador detector de moléculas que será integrado en espectrómetros de masas; unos instrumentos de medición que permiten, entre otras cosas, analizar con gran precisión los diferentes elementos químicos que forman un compuesto y que constituyen una de las industrias de instrumentación analítica de mayor crecimiento a nivel global.
Carbon nanotubes are the leading candidate to replace silicon in semiconductor chips after the decades-long run of silicon electronics runs out. And IBM is hoping to usher along that transition with a new breakthrough being announced today.
In semiconductor chip research, IBM has been racking up the breakthroughs for decades. And now it says that work is paying off with the creation of the first 7-nanometer chips. This means that the miniaturized electronics are so small that transistors on the chips are only 7 billionth of a meter in length. That’s 1,400 times smaller than a human hair.
Typically made from coconut shells or wood chips, activated carbon has a variety of uses, from refrigerator deodorizers to water filters to batteries. Its primary characteristic is its Swiss-cheese-like structure: it’s riddled with tiny holes or pores that increase the material’s surface area, enhancing its ability to catalyze chemical reactions and store electrical charges. But activated carbon has significant drawbacks: the pores are randomly sized and unconnected, and it tends to have high levels of impurities.
Graftonica est une nouvelle spin-off dans l'industrie des polymères de l'Université de Milan-Bicocca. Elle est dédiée au développement, la production et la commercialisation d'additifs nanotechnologiques pour une utilisation dans les industries du plastique et du caoutchouc.
Researchers at the University of California, Berkeley, say that by combining nanoscale materials with bacteria, they have opened the door to a new way of designing systems that could efficiently turn carbon dioxide, water, and sunlight into useful organic compounds—similar to what plants do through photosynthesis. Down the road, they say, the system could become a commercially viable way to produce high-value chemicals like drug precursors used by the pharmaceutical industry, or to store renewable energy in the form of liquid fuels.
Les nanotubes de carbone sont un assemblage particulier d'atomes de carbone dont les propriétés macroscopiques sont très intéressantes, au point qu'on les voit souvent comme des "matériaux de l'avenir" [1]. Les prouesses du Technion en matière de nanotubes ont été abondamment décrites par le Bulletin électronique Israël, notamment avec les fibres de nanotubes ultraconductrices du professeur Yeshayahu Talmon [2], les machines moléculaires à base de nanotubes du professeur Yaish Yuval [3] ou la silice poreuse du docteur Ester Segal [5]. L'équipe de cette dernière, qui officie au Russell Berrie Nanotechnology Institute du Technion, a récemment encore fait parler d'elle.
