New memory demoed running at 600 degrees Celsius for 60 hours

Posted by in categories: computing, electronics

A new type of memory has been demonstrated running at an astounding 600C for over 60 hours. Non-volatile ferroelectric diode (ferrodiode) memory devices can offer outstanding heat resistance and other properties that should enable cutting-edge data and extreme environment computing, claim researchers from the University of Pennsylvania in a Nature Electronics article, A scalable ferroelectronic non-volatile memory operating at 600°C.

Ferrodiode memory devices use a 45-nanometer thin layer of a synthesized AIScN (l0.68Sc0.32N) because of its ability to retain electrical states “after an external electric field is removed,” among “other desirable properties.” Ferrodiode memory has been tested running at 600 degrees Celsius for more than 60 hours while operating at less than 15 volts.

Researcher creates optical magnetometer prototype that detects errors in MRI scans

Posted by in categories: biotech/medical, electronics

Hvidovre Hospital has the world’s first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical sensors—and hopefully pave the way for MRI scans that are better, cheaper and faster.

Observation of the colliding process of plasma jets in the double-cone ignition scheme using an x-ray streak camera

Posted by in categories: electronics, energy

The double-cone ignition scheme is a novel approach with the potential to achieve a high gain fusion with a relatively smaller drive laser energy. To optimize the colliding process of the plasma jets formed by the CHCl/CD shells embedded in the gold cones, an x-ray streak camera was used to capture the spontaneous x-ray emission from the CHCl and CD plasma jets. High-density plasma jets with a velocity of 220 ± 25 km/s are observed to collide and stagnate, forming an isochoric plasma with sharp ends. During the head-on colliding process, the self-emission intensity nonlinearly increases because of the rapid increase in the density and temperature of the plasma jets. The CD colliding plasma exhibited stronger self-emission due to its faster implosion process. These experimental findings effectively agree with the two-dimensional fluid simulations.

Signs of Life would be Detectable in Single Ice Grain Emitted from Extraterrestrial Moons

Posted by in categories: alien life, electronics

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of Washington in Seattle and the Freie Universität Berlin shows that individual ice grains ejected from these planetary bodies may contain enough material for instruments headed there in the fall to detect signs of life, if such life exists.

“For the first time we have shown that even a tiny fraction of cellular material could be identified by a mass spectrometer onboard a spacecraft,” said lead author Fabian Klenner, a UW postdoctoral researcher in Earth and space sciences. “Our results give us more confidence that using upcoming instruments, we will be able to detect lifeforms similar to those on Earth, which we increasingly believe could be present on ocean-bearing moons.”

The world’s largest digital camera is ready to investigate the dark universe

Posted by in categories: cosmology, electronics

The 3,200-megapixel LSST camera is the size of a compact car and weighs in at 3 metric tons, which is about half the weight of a male African bush elephant. The LSST’s wide-field view will attempt to solve lingering mysteries surrounding dark energy, the force that accounts for around 70% of our universe’s matter-energy content and causes the expansion of the cosmos to accelerate.

The LSST will also investigate dark matter, the mysterious substance that accounts for around 85% of all stuff in the cosmos despite being invisible to us, as well as answer other astronomical questions as it creates what Željko Ivezić, Director of Rubin Observatory’s construction, describes as the “greatest movie of all time and the most informative map of the night sky ever assembled.”

Swallowable Sensors could Pinpoint Gut Movement Problems for Patients

Posted by in categories: biotech/medical, electronics

Scientists have developed an ingestible capsule dotted with sensors that can detect pressure in a patient’s guts and detect points of failure.

The ingestible system will give colorectal medical teams an unprecedented understanding of the movement of a patient’s digestive tract, or lack thereof. Instead of simply taking images of inside the guts, the system will sense whether it’s contracting, how much pressure is exerted and exactly where it might be inactive.

The system has been tested in a synthetic gut and animals. A patent for the technology is pending.
