Researchers have developed a new device to map the brain during surgery and distinguish between healthy and diseased tissues. The device provides higher resolution neural readings than existing tools used in the clinic and could enable doctors to perform safer, more precise brain surgeries.
Plasma propulsion concepts are gridded-ion thrusters that accelerate and emit more positively charged particles than negatively charged ones. To enable the spacecraft to remain charge-neutral, a 'neutralizer' injects electrons to exactly balance the positive ion charge in the exhaust beam, but this neutralizer requires additional power from the spacecraft. Researchers are investigating how the radio-frequency self-bias effect can be used to remove the neutralizer altogether.
A lightweight, comfortable jacket that can generate the power to light up a jogger at night may sound futuristic, but a materials scientist could make one today. In a new paper, she and colleagues outline a way to apply breathable, pliable, metal-free electrodes to fabric and off-the-shelf clothing so it feels good to the touch and also transports enough electricity to power small electronics.
New research investigated the full life cycle impact of one promising 'second-generation biofuel' produced from short-rotation oak. The study found that second-generation biofuels made from managed trees and perennial grasses may provide a sustainable fuel resource.
Scientists are building on the proven concept of autonomous cooperative soaring of unmanned aerial vehicles (UAVs), which enables long endurance flights of unmanned sailplanes that use the power of the Sun.
A research team has developed lithium-air batteries with very high electric storage capacity15 times greater than the capacity of conventional lithium-ion batteries using carbon nanotubes (CNT) as an air electrode material.
Many elements are required for making the energy system more sustainable. Among them are smart solar storage systems, smartly interconnected energy grids, and electricity-based synthetic fuels (e-fuels).
In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
A 54 percent majority of US adults believe that 'government regulations are necessary to encourage businesses and consumers to rely more on renewable energy sources,' while 38 percent support the notion that 'the private marketplace will ensure that businesses and consumers rely more on renewable energy sources, even without government regulations,' according to a new survey.
Transporting methane from gas wellheads to market provides multiple opportunities for this greenhouse gas to leak into the atmosphere. Now, an international team of researchers has taken the first step in converting methane directly to electricity using bacteria, in a way that could be done near the drilling sites.
Smart windows that act as blinds in the summer and let all the sunlight through in the winter. That's the idea of the reflective windows that are able to reflect invisible infrared light but allow visible light through. In addition these windows can be 'switched on and off'. This new technology cuts the energy consumption for cooling and heating buildings by 12%.
Physicists have discovered a catalyst that can split water into hydrogen and oxygen, composed of easily available, low-cost materials and operating far more efficiently than previous catalysts. That would solve one of the primary hurdles remaining in using water to produce hydrogen, one of the most promising sources of clean energy.
Researchers have found a way to clean particles from water by mixing in carbon dioxide. The gas changes the water's chemistry, which causes particles to move to one side of the water depending on their chemical charge. By taking advantage of the motion, the researchers can split a water stream and filter out suspended particles.
Solar power can cover up to 40% of the electricity needs of a typical household. Going beyond that level becomes really expensive: using batteries coupled with solar panels would be twice as expensive as using the power grid.
The process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries. Researchers have developed a method for electroplating lithium-ion battery cathodes, yielding high-quality, high-performance battery materials that could also open the door to flexible and solid-state batteries.
Data science has been used by researchers to determine and predict the effects of exposure to weather and other conditions on materials in solar panels. Using data science to predict the deterioration of such materials could lead to finding new ways to extend their lifetime, the researchers say.
