A new standard in robotics

Known as the Yale-CMU-Berkeley (YCB) Object and Model Set, the intent is to provide universal benchmarks for labs specializing in robotic manipulation and prosthetics around the world.

Major advance in solar cells made from cheap, easy-to-use perovskite

Solar cells made from an inexpensive and increasingly popular material called perovskite can more efficiently turn sunlight into electricity using a new technique to sandwich two types of perovskite into a single photovoltaic cell.

Atomic sandwiches could make computers more energy efficient

Researchers have engineered a material that could lead to a new generation of computing devices, packing in more computing power while consuming a fraction of the energy that today's electronics require.

Neural dust opens door to implantable self powered wearables

Engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.

Novel self-assembly can tune the electronic properties of graphene

A new self-assembly mechanism that drives negatively charged molecules to clump together to form islands when graphene is supported by an electrical insulator.

Discovery could dramatically boost perovskite efficiency

Scientists have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.

Trapped electrons to blame for lack of battery efficiency

Research has the potential to create more efficient batteries by shedding light on the cause of one of their biggest problems -- a "traffic jam" of ions that slows down their charging and discharging process.

Extend life and improved performance of fuel cell electrodes

Researchers have developed a practical and physically-based way of treating the surface of materials called perovskite oxides, to make them more durable and improve their performance. These materials are promising candidates to serve as electrodes in energy-conversion devices such as fuel cells and electrolyzers.

24m Technologies

24M is a spin-out of battery company A123 that has developed a semi-solid, flexible electrode structure for their Li-ion batteries. We recently interviewed President and CEO Throop Wilder.

PolyPlus Battery Company

Polyplus is a US company that develops solid-state and semi-solid state electrolytes for lithium-air, lithium-sulphur and advanced lithium-ion batteries. After 20 years of R&D, they are now ready to enter both military and consumer electronics applications.

Seeo

Seeo is a US battery start-up that was recently acquired by Bosch. They have developed an innovative solid polymer electrolyte that can be coupled with lithium metal to boost gravimetric and volumetric energy density, while making the device safer.

New path forward for next-generation lithium-ion batteries

In the quest for a radically better lithium-ion battery, a promising direction is the so-called "lithium-rich" cathode, in which the cathode contains a higher proportion of lithium than normal.

Nanomaterial to drive new generation of solar cells

Physicists have discovered radical new properties in a nanomaterial, opening new possibilities for highly efficient thermophotovoltaic cells that could one day harvest heat in the dark and turn it into electricity.

Cambrios restarts Its silver nanowire business

Champ Great has formed a new company, Cambrios Advanced Materials Corporation that will continue research, development and sales of silver nanowire inks.

New catalyst offers efficient storage of alternative energies

Researchers have designed the most efficient catalyst for storing energy in chemical form, by splitting water into hydrogen and oxygen, just like plants do during photosynthesis.

New fuel cell design powered by graphene-wrapped nanocrystals

Hydrogen is the lightest and most plentiful element on Earth and in our universe. So it shouldn't be a big surprise that scientists are pursuing hydrogen as a clean, carbon-free, virtually limitless energy source for cars and for a range of other uses, from portable generators to telecommunications towers—with water as the only byproduct of combustion.

New form of electron-beam imaging

The MIDI-STEM technique could prove particularly useful for directly viewing nanoscale objects with a mixture of heavy and light materials, such as some battery and energy-harvesting materials, that are otherwise difficult to view together at atomic resolution.

X-rays reveal details of plastic solar cell production

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear.

Seeing the big picture in photosynthetic light harvesting

To understand the photosynthetic light-harvesting that takes place inside the chloroplast of a leaf, you can't just study the activity of a single antenna protein.

What new wearable sensors can reveal from perspiration

Researchers say this device is the first fully integrated electronic system that can provide continuous, non-invasive monitoring of multiple biochemicals in sweat.
