Study reveals origin of superconductivity in nickelates

Posted by in categories: entertainment, materials

Nickelates are a material class that has excited scientists because of its recently discovered superconducting ability, and now a new study led by Cornell has changed where scientists thought this ability might originate, providing a blueprint for how more functional versions might be engineered in the future.

Superconductivity was predicted in nickel-based oxide compounds, or nickelates, more than 20 years ago, yet only realized experimentally for the first time in 2019, and only in samples that are grown as very thin, crystalline films—less than 20 nanometers thick—layered on a supporting substrate material.

Researchers worldwide have been working to better understand the microscopic details and origins of superconductivity in nickelates in an effort to create samples that successfully superconduct in macroscopic “bulk” , but have yet to be successful. This limitation led some researchers to speculate that superconductivity was not being hosted in the nickelate film, but rather at the atomic interface where the film and substrate meet.

Artificial Cells — The Powerhouse of the Future

Posted by in categories: bioengineering, biotech/medical

Assessing how energy-generating synthetic organelles could sustain artificial cells.

Researchers have assessed the progress and challenges in creating artificial mitochondria and chloroplasts for energy production in synthetic cells. These artificial organelles could potentially enable the development of new organisms or biomaterials. The researchers identified proteins as the most crucial components for molecular rotary machinery, proton transport, and ATP production, which serves as the cell’s primary energy currency.

Energy production in nature is the responsibility of chloroplasts and mitochondria and is crucial for fabricating sustainable, synthetic cells in the lab. Mitochondria are not only “the powerhouses of the cell,” as the middle school biology adage goes, but also one of the most complex intracellular components to replicate artificially.

Is God A Virus? | Echopraxia

Posted by in categories: alien life, mathematics, physics, supercomputing

Echopraxia is a book set in one of the most interesting sci-fi universes that I have covered on this channel. It is technically a sequel to Blindsight, but it is not necessary that you read Blindsight to understand Echopraxia is set in the late 21 century. About 14 years after man’s first contact with alien life.

This book brings up one of the most interesting concepts I’ve ever encountered in any sci-fi book ever. And that is the concept of the “Digital Universe” and God as a Virus. Now this is a concept that comes from the field of digital physics, which keep in mind is all theoretical. It is based on the premise that the universe is pure mathematics at its base, every event that occurs can be thought of as a kind of computation. This could mean that the universe is a simulation, but that is not necessary for the idea to work.

Discovery of a new topological phase could lead to exciting developments in nanotechnology

Posted by in categories: nanotechnology, physics

Cambridge researchers have discovered a new topological phase in a two-dimensional system, which could be used as a new platform for exploring topological physics in nanoscale devices.

Two-dimensional materials such as graphene have served as a playground for the experimental discovery and theoretical understanding of a wide range of phenomena in physics and . Beyond graphene, there are a large number 2D materials, all with different physical properties. This is promising for potential applications in nanotechnology, where a wide range of functionality can be achieved in devices by using different 2D materials or stacking combinations of different layers.

It was recently discovered that in materials such as (hBN), which are less symmetric than graphene, ferroelectricity occurs when one layer slides over the other and breaks a symmetry. Ferroelectricity is the switching of a material’s with an , which is a useful property for information processing and memory storage.

What if The Universe Started With a Dark Big Bang?

Posted by in categories: cosmology, particle physics, quantum physics

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.

In the standard cosmological picture the early universe was a very exotic place. Perhaps the most momentous thing to happen in our cosmos was the event of inflation, which at very early times after the Big Bang sent our universe into a period of extremely rapid expansion.

CRISPR Is The Future.

Welcome to the future!

It is the year 2050, and the world is facing a crisis. Climate change has caused widespread devastation, and the planet’s resources are dwindling. Famine and disease are rampant, and humanity is on the brink of collapse. But amidst the chaos, a new hope emerges.

Colloids get creative to pave the way for next generation photonics

Posted by in categories: computing, particle physics, solar power, sustainability

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.

The structure, which naturally occurs in the wing scales of some species of butterfly, can function as a photonic crystal, according to a new study by researchers at the University of Birmingham. It can be used to control light in the visible range of the spectrum, for applications for lasers, sensors, and also devices for harvesting solar energy.

Their computational study, published in Advanced Materials, demonstrates that the complex gyroid structure can be self-assembled from designer in the range of hundreds of nanometers.

Origin of Life: The Scientific Response

Posted by in categories: chemistry, physics

The first possible scenarios for life’s origin is that life may simply have been a miracle. It may have been a divine act of intervention. If so, then the origin of life is not a scientific question. There is no experiment one can propose or an observation one can make.

Yet, it’s equally possible that the origin of life was an event that’s fully consistent with the known laws of physics and chemistry, but an extremely improbable, perhaps unique event; perhaps an event that only took place on Earth. Once again, it’s really not amenable to scientific study, because we can’t go into the laboratory and study a unique event.

And then there is a third possibility, and that’s that life is an inevitable consequence of chemistry. That, given an appropriate environment—an appropriate planet with water, for example—and sufficient time, that life always arises.
