New solution to capture microplastics before they enter waterways (07/05/2020)

A thousand liters of seawater can contain up to 8.3 million particles of microplastics. Until now, identifying these very small particles has been difficult—usually they are only detected once they have accumulated in the bodies of fish. A method developed at VTT utilizes nanocellulose structures for early particle identification. Nanocellulose would allow particles to be captured even before they enter waterways.

State-of-the-art lasers at the micro level (07/05/2020)

Many emerging technologies rely on high-quality lasers. Laser-based LiDAR sensors can provide highly accurate scans of three-dimensional spaces, and as such are crucial in applications ranging from autonomous vehicles to geological mapping technologies and emergency response systems. High-quality lasers are also a key part of the high-speed, high-volume data centers that are the backbone of the internet.

Next-generation batteries take major step toward commercial viability (28/04/2020)

Lithium-sulfur batteries have been hailed as the next big step in battery technology, promising significantly longer use for everything from cellphones to electric vehicles on a single charge, while being more environmentally sustainable to produce than current lithium-ion batteries. However, these batteries don't last as long as their lithium-ion counterparts, degrading over time.

Building block for quantum computers more common than previously believed (28/04/2020)

Advanced, fault-tolerant quantum computers may be closer to reach than scientists have projected, according to recent advances reported by Johns Hopkins researchers in a new study recently published in Physical Review Letter.

Wide bandgap semiconductor devices based on silicon carbide may revolutionize electronics (28/04/2020)

Growth of high-quality substrates for microelectronic applications is one of the key elements helping drive society toward a more sustainable green economy. Today, silicon plays a central role within the semiconductor industry for microelectronic and nanoelectronic devices.

Biohybrid battery harvests energy from electric bacteria (23/04/2020)

Some bacteria are known to produce their own electricity, which could make them useful in batteries and fuel cells. But so far, attempts have been inefficient and inflexible. Now, researchers at Karlsruhe Institute of Technology (KIT) have created a “biohybrid” system built around a hydrogel that can support the microbes while effectively collecting their energy.

Semi-transparent solar cells could rival rooftop solar for efficiency (23/04/2020)

Windows capable of harvesting energy from the sun have been on the horizon for a number of years, but they're yet to help cut down a building's energy costs. A new development from Australian researchers may change that.

Controlling ion transport for energy, environment (23/04/2020)

Understanding and controlling ion transport in porous materials and at hydrophobic interfaces is critical to a wide variety of energy and environmental technologies, ranging from ion selective membranes, drug delivery and biosensing to ion batteries and supercapacitors.

Discovery offers new avenue for next-generation data storage (20/04/2020)

The demands for data storage and processing have grown exponentially as the world becomes increasingly connected, emphasizing the need for new materials capable of more efficient data storage and data processing.
