Posted by in categories: quantum physics, solar power, sustainability

Circa 2021

Perovskite quantum dots film has better mechanical stability and structural integrity compared to bulk thin film. Here, the authors demonstrate higher endurance of quantum dot films and develop hybrid CsPbI3 QD/PCBM device with PCE of 15.1% and 12.3% on rigid and flexible substrates, respectively.

Scientific breakthrough cures memory loss in mice

Posted by in categories: biotech/medical, neuroscience

Researchers at Stanford University are reversing symptoms of Alzheimer’s in mice using a strange tactic — they’re infusing elderly mice with spinal fluid from younger ones.

Many medical breakthroughs that benefit humans are discovered by conducting trials on mice.

Though we look nothing alike, almost all the genes found in mice have similar functions to genes in humans. We get diseases for the same reasons, meaning scientists can study illnesses closely in mice to understand how they manifest in us.

Rapidly descending dark energy and the end of cosmic expansion

Posted by in categories: cosmology, quantum physics

Although the universe is expanding at an accelerating rate today, this paper presents a simple mechanism by which a dynamical form of dark energy (known as quintessence) could cause the acceleration to come to end and smoothly transition from expansion to a phase of slow contraction. That raises questions, How soon could this transition occur? And at what point would it be detectable? The conclusions are that the transition could be surprisingly soon, maybe less than 100 million y from now, and yet, for reasons described in the main text, it is not yet detectable today. The scenario is not far-fetched. In fact, it fits naturally with recent theories of cyclic cosmology and conjectures about quantum gravity.

New Quantum Well Solar Cell Just Set a World Record For Efficiency

Posted by in categories: quantum physics, satellites, solar power, sustainability

“there’s a new record to report: a new solar cell has hit 39.5 percent efficiency ”.

Scientists keep on pushing the efficiency of solar panels higher and higher, and there’s a new record to report: a new solar cell has hit 39.5 percent efficiency under the standard 1-sun global illumination conditions.

That 1-sun marker is simply a standardized way of measuring a fixed amount of sunlight, and almost 40 percent of that radiation can now be converted into electricity. The previous record for this type of solar panel material was 39.2 percent efficiency.

Imec Presents Sub-1nm Process and Transistor Roadmap Until 2036: From Nanometers to the Angstrom Era

Posted by in categories: computing, materials

Imec plots a course to 1nm chips, and beyond.

Imec, the most advanced semiconductor research firm in the world, recently shared its sub-‘1nm’ silicon and transistor roadmap at its Future Summit event in Antwerp, Belgium. The roadmap gives us a rough idea of the timelines through 2036 for the next major process nodes and transistor architectures the company will research and develop in its labs in cooperation with industry giants, like TSMC, Intel, Samsung, and ASML, among many others.

The roadmap includes breakthrough transistor designs that evolve from the standard FinFET transistors that will last until 3nm, to new Gate All Around (GAA) nanosheets and forksheet designs at 2nm and A7 (seven angstroms), respectively, followed by breakthrough designs like CFETs and atomic channels at A5 and A2. As a reminder, ten Angstroms are equal to 1nm, so Imec’s roadmap encompasses sub-‘1nm’ process nodes.
