nanoFlowcell: the new Concept of Sustainable Electromobility

Adrian — Wed, 22 Nov 2023 20:12:24 +0000

nanoFlowcell can deliver electromobility Electromobility, or the use of electric vehicles (EVs) for transportation, is widely regarded as a key solution to reduce greenhouse gas emissions, improve air quality, and enhance energy security. However, current EVs face several challenges, such as limited driving range, high battery cost and weight, long charging time, and environmental impact […]

Nanosensors which translate plants signals

Adrian — Sat, 18 Apr 2020 17:52:04 +0000

MIT engineers have found a way to monitor plants, to observe their response to different types of stimuli, from swearing, insect bites, or infections, to aggressive light, or others, using a nanosensor built from carbon nanotubes. The sensors are embedded in the leaves of plants, which use hydrogen peroxide to chemically communicate inside their leaves, […]

Cleaning objects at nanoscale

Adrian — Fri, 17 Apr 2020 22:47:42 +0000

When I thought I saw all in the field of cleaning, I found out that a team of German scientists at FAU – Friedrich-Alexander University from Nürnberg, Germany have completed a new method for mechanical cleaning of surfaces at nanoscale. Their technique removes even the tiniest contaminants down to the atomic scale, performing a cleaning […]

Green energy from snowfall produced by Snow-TENG

Adrian — Thu, 13 Jun 2019 23:22:54 +0000

A team of researcher and colleagues from the University of California – UCLA conducted by senior author Richard Kaner, have designed a brand new device that creates electricity from snowing. They called it Snow-TENG, a snow based triboelectric nanogenerator, which would be theoretically inexpensive, small and you can say it, thin and flexible like a […]

The trees as raw material for elastic high-capacity battery

Adrian — Tue, 02 Jun 2015 22:53:21 +0000

I never thought that is possible to make elastic high-capacity battery from wood pulp. Now it is obviously. A very good team of researchers from KTH Royal Swedish Institute of Technology and Stanford University made this come true. They used nanocellulose broken down from tree fibre to produce a kind of elastic foam designed to […]

Bringing down the cost of fuel cells

Gabriel — Sat, 23 Jun 2012 11:35:16 +0000

Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may […]

Self-Assembling Nanocubes

Gabriel — Tue, 19 Jun 2012 19:16:26 +0000

Researchers at the University of California, San Diego Jacobs School of Engineering have developed a technique that enables metallic nanocrystals to self-assemble into larger, complex materials for next-generation antennas and lenses. The metal nanocrystals are cube-shaped and, like bricks or Tetris blocks, spontaneously organize themselves into larger-scale structures with precise orientations relative to one another. […]

Researchers use nanotechnology to harness the power of fireflies

Gabriel — Sat, 16 Jun 2012 18:37:50 +0000

What do fireflies, nanorods, and Christmas lights have in common? Someday, consumers may be able to purchase multicolor strings of light that don’t need electricity or batteries to glow. Scientists at Syracuse University found a new way to harness the natural light produced by fireflies (called bioluminescence) using nanoscience. Their breakthrough produces a system that […]

ORNL microscopy reveals workings behind promising inexpensive catalyst

Gabriel — Tue, 12 Jun 2012 19:44:57 +0000

A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies by delivering a substitute for expensive platinum catalysts. The precious metal platinum has long been prized for its ability to spur key chemical reactions in a process called catalysis, but at more than $1,000 an […]

Nanocable could be big boon for energy storage

Gabriel — Thu, 07 Jun 2012 19:37:56 +0000

Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable, which is described this week in Nature Communications, was produced with techniques pioneered in the nascent graphene research field […]
