Hot new solar cell

System converts solar heat into usable light, increasing device’s overall efficiency

26-May-2016

A team of MIT researchers has for the first time demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity. Ever since 1961 it has been known that there is an absolute theoretical ...

How nanoparticles flow through the environment

13-May-2016

Carbon nanotubes remain attached to materials for years while titanium dioxide and nanozinc are rapidly washed out of cosmetics and accumulate in the ground. Researchers from the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64) have developed a new model to track ...

Cleaning up hybrid battery electrodes improves capacity and lifespan

25-Apr-2016

Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with a gentle-sounding way of making electrodes. Called ion soft-landing, the high-precision technique resulted in electrodes that could store a ...

3-D printing for building densely populated electronic assemblies investigated

21-Apr-2016

As detector assemblies get smaller and denser -- packed with electronic components that all must be electrically connected to sense and read out signals -- it's becoming increasingly more challenging to design and manufacture these all-important instrument devices. A team of NASA technologists at ...

Carbon Nanotubes for Advanced Interconnects

21-Mar-2016

CEA, Fraunhofer IPMS, IBM, Aixtron, CNRS, GSS and University of Glasgow start joint project on Carbon Nanotube Composite Interconnects (CONNECT) to enable future CMOS scaling. A European consortium of seven research and industry partners have started a joint four million Euro project over three ...

A nontoxic way of generating portable power

16-Mar-2016

The batteries that power the ubiquitous devices of modern life, from smartphones and computers to electric cars, are mostly made of toxic materials such as lithium that can be difficult to dispose of and have limited global supplies. Now, researchers at MIT have come up with an alternative system ...

Test for nanomanufacturing quality control

08-Mar-2016

Manufacturers may soon have a speedy and nondestructive way to test a wide array of materials under real-world conditions, thanks to an advance that researchers at the National Institute of Standards and Technology (NIST) have made in roll-to-roll measurements. Roll-to-roll measurements are ...

Carbon nanotubes improve metal's longevity under radiation

04-Mar-2016

One of the main reasons for limiting the operating lifetimes of nuclear reactors is that metals exposed to the strong radiation environment near the reactor core become porous and brittle, which can lead to cracking and failure. Now, a team of researchers at MIT and elsewhere has found that, at ...

New process enables easier isolation of carbon nanotubes

25-Jan-2016

Manufacture of longer, thinner, and uncontaminated carbon nanotubes, and successfully isolating them, have been ongoing challenges for researchers. A newly developed method has opened up new possibilities in carbon nanotube development. Researchers at Kyushu University's Department of Applied ...

Continuing the search for better energy materials

21-Jan-2016

Throughout almost two decades of work with energy-related materials, Zhifeng Ren has received a number of grants from the Department of Energy (DOE). His latest DOE grant of $561,275 continues funding he has received for almost 20 years for work in basic energy science. Ren, M.D. Anderson Chair ...
