New microchip links two Nobel Prize-winning techniques      (via sciencedaily.com) 

Physicists have built a new technology on a microchip by combining two Nobel Prize-winning techniques. This microchip could measure distances in materials at high precision, for example underwater or for medical imaging. Because the technology uses sound vibrations instead of light, it is useful for high-precision position measurements in opaque materials. There's no need for complex feedback loops or for tuning certain parameters to get it to operate properly. This makes it a very simple and low-power technology, that is much easier to miniaturize on a microchip. What makes it special is that it doesn't need any precision hardware and is therefore easy to produce. It only requires inserting a laser, and nothing else. The instrument could lead to new techniques to monitor the Earth's climate and human health.

New invention: The oxygen-ion battery      (via sciencedaily.com) 

An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.

Batteries: Passivation layer mystery solved      (via sciencedaily.com) 

In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.

Scientists find a common thread linking subatomic color glass condensate and massive black holes      (via sciencedaily.com) 

Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.

Sculpting quantum materials for the electronics of the future      (via sciencedaily.com) 

The development of new information and communication technologies poses new challenges to scientists and industry. Designing new quantum materials -- whose exceptional properties stem from quantum physics -- is the most promising way to meet these challenges. An international team has designed a material in which the dynamics of electrons can be controlled by curving the fabric of space in which they evolve. These properties are of interest for next-generation electronic devices, including the optoelectronics of the future.

Stalactites and stalagmites in the battery?      (via sciencedaily.com) 

They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the life cycle of such batteries and targeted processes that reduce it. With their findings, more durable solid-state batteries could be realized in the future.

Observations open door to improved luminous efficiency of organic LEDs      (via sciencedaily.com) 

Scientists succeeded in directly observing how LECs -- which are attracting attention as one of the post-organic LEDs -- change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is expected to reveal detailed electroluminescence processes and lead to the early detection of factors that reduce the efficiency of electroluminescence.

High-speed super-resolution microscopy via temporal compression      (via sciencedaily.com) 

Recently, a research team resolved the contradiction between spatial resolution and imaging speed in optical microscopy. They achieved high-speed super-resolution by developing an effective technique termed temporal compressive super-resolution microscopy (TCSRM). TCSRM merges enhanced temporal compressive microscopy with deep-learning-based super-resolution image reconstruction. Enhanced temporal compressive microscopy improves the imaging speed by reconstructing multiple images from one compressed image, and the deep-learning-based image reconstruction achieves the super-resolution effect without reduction in imaging speed. Their iterative image reconstruction algorithm contains motion estimation, merging estimation, scene correction, and super-resolution processing to extract the super-resolution image sequence from compressed and reference measurements.
