Scientists print all-liquid 3-D structures

Scientists have developed a way to print 3-D structures composed entirely of liquids. Using a modified 3-D printer, they injected threads of water into silicone oil — sculpting tubes made of one liquid within another liquid.

Applying machine learning to the universe's mysteries

Computers can beat chess champions, simulate star explosions, and forecast global climate. We are even teaching them to be infallible problem-solvers and fast learners.

Ideal material for smart photovoltaic windows

Imagine that when a window is darkened, it simultaneously produces electricity. Such a material - a photovoltaic glass that is also reversibly thermochromic - is a green technology researchers have long worked toward, and now, scientists have demonstrated a way to make it work.

How CRISPR proteins find their target

Researchers have discovered how Cas1-Cas2, the proteins responsible for the ability of the CRISPR immune system in bacteria to adapt to new viral infections, identify the site in the genome where they insert viral DNA so they can recognize it later and mount an attack.

New class of 'soft' semiconductors could transform HD displays

A new type of semiconductor may be coming to a high-definition display near you.

Device pulls water from dry air, powered only by the sun

Imagine a future in which every home has an appliance that pulls all the water the household needs out of the air, even in dry or desert climates, using only the power of the sun.

Project turns waste heat to electricity

Vast amounts of energy are wasted every year in the form of heat. A new project seeks to efficiently capture that heat and convert it to electricity.

Illuminating Performance Characteristics Of Battery Materials Using Synchrotron Techniques: Advanced NMCs, Sodium-Ion Batteries And Solid Garnet Type Electrolytes

Lawrence Berkeley National Laboratory, United States

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.

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.

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.
