Researchers have developed a highly accurate single cell sorting technology using focused sound waves. This new technology enables rapid and accurate isolation of single cells from complex biological samples, which will facilitate the broad application of single cell analysis toward precision medicine.
Physicists have investigated a class of materials that exhibit characteristics of topological insulators. During these studies they discovered a transition between two different topological phases, one of which is ferroelectric.
Computer engineering researchers have developed new software and hardware designs that should limit programming errors and improve system performance in devices that use non-volatile memory technologies.
Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity.
Researchers take inspiration from natural chemical processes based on hydrogenase and photosystem II, to produce a single metal catalyst with both fuel cell and solar cell functionalities. The combination of these two processes into one system suggests great potential for biologically inspired energy generation technologies.
We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of engineers has a different type of lithium sulfur battery that could be more efficient, less expensive and safer.
Motivated by the challenge to drastically reduce the cost of storing renewable energy on the grid while capturing more of it, a group of scientists has developed a battery powered by sulfur, air, water, and salt -- all readily available materials -- that is nearly 100 times less expensive to produce than batteries currently on the market and can store twice as much energy as a lead-acid battery. The inventors present their prototype in Joule.
A ceramic-based mechanical pump able to operate at record temperatures of more than 1,400 degrees Celsius (1,673 Kelvin) can transfer high temperature liquids such as molten tin, enabling a new generation of energy conversion and storage systems.
The same electrostatic charge that can make hair stand on end and attach balloons to clothing could be an efficient way to drive atomically thin electronic memory devices of the future, according to a new study. Scientists have found a way to reversibly change the atomic structure of a 2-D material by injecting it with electrons. The process uses far less energy than current methods for changing the configuration of a material's structure.
It is time to stop discussing whether electric cars are good or bad. Instead industry, authorities and policy-makers need to work together to make them as eco-friendly as possible. One researcher now provides concrete advice and tools showing how life cycle assessment can assist in the development of electric cars.
A new method has been proposed that simultaneously optimizes individual office workers' productivity and energy consumption costs by automating the control of indoor environmental conditions including air quality, temperature and lighting.
Researchers have determined how electrocatalysts can convert carbon dioxide to carbon monoxide using water and electricity. The discovery can lead to the development of efficient electrocatalysts for large scale production of synthesis gas -- a mixture of carbon monoxide and hydrogen.
A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.
