Strategically important metals such as tungsten or indium are often trapped in massive rocks. Due to their complex metal phases and mineralogical composition,…
A little over a year ago, Caltech's Lihong Wang developed the world's fastest camera, a device capable of taking 10 trillion pictures per second. It is so fast…
The benefits of an RFB system depend on many aspects: The perfect, redox-active material should smoothly accept or release electrons, while being soluble,…
Most neutron detectors work based on one of two different technologies. Some, like those based on helium, are gas-filled. Others, like those based on lithium…
Intentional defects in batteries have given Rice University scientists a window into the hazards of pushing lithium-ion cells too far.
By growing thin perovskite films on substrates with different compositions, engineers at the University of California San Diego have invented a way of…
Directional antennas convert electrical signals to radio waves and emit them in a particular direction, allowing increased performance and reduced…
After having already succeeded in producing aluminium coils by investment casting in recent years, it was an obvious goal of the department “Casting Technology…
On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant…
It is about organic photovoltaic cells (OPV cells), which are less efficient than traditional silicon-based solar cells, but are flexible and transparent….
The new coating — engineered from samarium nickel oxide, a unique tunable material — employs a bit of temperature trickery.
Heat pumps based on compressors are used for heating and cooling. However, the refrigerants used in the systems can be harmful to climate, health and the…
A cluster of industrial chemicals known by the shorthand term “PFAS” has infiltrated the far reaches of our planet with significance that scientists are only…
Our use of battery-operated devices and appliances has been increasing steadily, bringing with it the need for safe, efficient, and high-performing power…
Metalenses — flat surfaces that use nanostructures to focus light — are poised to revolutionize everything from microscopy to cameras, sensors, and displays….
If a person goes overboard on the high seas and gets out of sight, it is almost impossi-ble to detect the person in the water using the conventional ships’…
