Researchers have found that a material which incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn't include the water layers. The finding raises some interesting questions about the behavior of liquids when confined at this scale and holds promise for shaping future energy-storage technologies.
Researchers have used a nanosecond pulsed electric field to extract hydrocarbons from microalgae. By using the shorter duration pulse, they were able to extract a large amount of hydrocarbons from the microalgae in a shorter amount of time, using less energy, and in a more efficient manner than current methods.
In 'Minority Report,' the protagonist uses gloves that give him the power of virtual manipulation. The light seems to allow him to control the screen as if it were a touchscreen, but he's touching nothing but air. That technology is still science fiction, but a new study may bring it closer to reality. Researchers report that they have discovered the photodielectric effect, which could lead to laser-controlled touch displays.
Solar cells convert the sun's energy into electricity by converting photons into electrons. A new solar cell design could raise the energy conversion efficiency to over 50% by absorbing the spectral components of longer wavelengths that are usually lost during transmission through the cell.
Researchers have created a unique video that shows oxygen bubbles inflating and later deflating inside a tiny lithium-air battery. The knowledge gained from the video could help make lithium-air batteries that are more compact, stable and can hold onto a charge longer.
Lithium-oxygen fuel cells boast energy density levels comparable to fossil fuels and are thus seen as a promising candidate for future transportation-related energy needs. Several roadblocks stand in the way of realizing that vision. An engineering lab has focused on one of those roadblocks -- the loss of battery power, also known as capacity fade.
In a world-first, researchers have imaged electrons moving in graphene using a quantum probe found only in diamonds. The technique could be used to understand electron behavior and allow researchers to improve the reliability and performance of existing and emerging technologies. These images could reveal the microscopic behavior of currents in quantum computing devices, graphene and other 2-D materials, and be used to develop next generation electronics, energy storage (batteries), flexible displays and bio-chemical sensors.
Efforts to reduce our dependence on fossil fuels are advancing on various significant fronts. Initiatives include research focused on more efficient production of gaseous hydrogen fuel by using solar energy to break water down into components of hydrogen and oxygen. Scientists have now reported a key breakthrough in the basic science essential for progress toward this goal.
Researchers inspired by efforts to promote green energy, are exploring the factors driving commercial customers in Southern California, both large and small, to purchase and install solar photovoltaic (PV) systems. They built a model for commercial solar PV adoption to quantify the impact of government incentives and solar PV costs.
The annual potential of solar energy far exceeds the world's energy consumption, but the goal of using the sun to provide a significant fraction of global electricity demand is far from being realized.
Technion researchers have a developed safe and efficient way to produce hydrogen on board a plane in flight. Using aluminum particles and (fresh or waste), the technology could one day help meet in-flight energy needs on commercial aircraft.
A new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable has now been developed, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage.
A new study has introduced a new battery charging technology that uses light to charge batteries. This newly-developed power source is designed to work under sunlight and indoor lighting, allowing users to power their portable electronics anywhere with access to light. In addition, the new device could power electric devices even in the absence of light.
A new way to detect nuclear materials has been developed by researchers. Made of graphene and carbon nanotubes, the researchers' detector far outpaces any existing one in its ultrasensitivity to charged particles, minuscule size, low-power requirements, and low cost.
Researchers have used waste glass bottles and a low-cost chemical process to create nanosilicon anodes for high-performance lithium-ion batteries. The batteries will extend the range of electric vehicles and plug-in hybrid electric vehicles, and provide more power with fewer charges to personal electronics like cell phones and laptops.
