Quantum behavior at room temperature: When laser light makes materials magnetic

The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers from Stockholm University, the Nordic Institute for Theoretical Physics and the Ca' Foscari University of Venice have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature—and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage. Within a few decades, the advancement of quantum technology is expected to revolutionize several of society's most important areas and pave the way for completely new technological possibilities in communication and energy. Of particular interest for researchers in the field are the peculiar and bizarre properties of quantum particles—which deviate completely from the laws of classical physics and can make materials magnetic or superconducting.

Researchers create stable superconductor enhanced by magnetism

An international team including researchers from the University of Würzburg has succeeded in creating a special state of superconductivity. This discovery could advance the development of quantum computers. The results are published in Nature Physics. Superconductors are materials that can conduct electricity without electrical resistance—making them the ideal base material for electronic components in MRI machines, magnetic levitation trains and even particle accelerators. However, conventional superconductors are easily disturbed by magnetism. An international group of researchers has now succeeded in building a hybrid device consisting of a stable proximitized-superconductor enhanced by magnetism and whose function can be specifically controlled. They combined the superconductor with a special semiconductor material known as a topological insulator. "Topological insulators are materials that conduct electricity on their surface but not inside. This is due to their unique topological structure, i.e., the special arrangement of the electrons," explains Professor Charles Gould, a physicist at the Institute for Topological Insulators at the University of Würzburg (JMU). "The exciting thing is that we can equip topological insulators with magnetic atoms so that they can be controlled by a magnet."

to all my researchers, students and people in general who love learning: if you don't know this already, i'm about to give you a game changer

connectedpapers

the basic rundown is: you use the search bar to enter a topic, scientific paper name or DOI. the website then offers you a list of papers on the topic, and you choose the one you're looking for/most relevant one. from here, it makes a tree diagram of related papers that are clustered based on topic relatability and colour-coded by time they were produced!

for example: here i search "human B12"

i go ahead and choose the first paper, meaning my graph will be based around it and start from the topics of "b12 levels" and "fraility syndrome"

here is the graph output! you can scroll through all the papers included on the left, and clicking on each one shows you it's position on the chart + will pull up details on the paper on the right hand column (title, authors, citations, abstract/summary and links where the paper can be found)

you get a few free graphs a month before you have to sign up, and i think the free version gives you up to 5 a month. there are paid versions but it really depends how often you need to use this kinda thing.

Advanced plastics could usher in lighter, cheaper, more energy-efficient product components, including those used in vehicles, LEDs and computers—if only they were better at dissipating heat.

A new technique that can change plastic’s molecular structure to help it cast off heat is a promising step in that direction.

Skip Google for Research

As Google has worked to overtake the internet, its search algorithm has not just gotten worse.  It has been designed to prioritize advertisers and popular pages often times excluding pages and content that better matches your search terms 

As a writer in need of information for my stories, I find this unacceptable.  As a proponent of availability of information so the populace can actually educate itself, it is unforgivable.

Below is a concise list of useful research sites compiled by Edward Clark over on Facebook. I was familiar with some, but not all of these.

⁂

Google is so powerful that it “hides” other search systems from us. We just don’t know the existence of most of them. Meanwhile, there are still a huge number of excellent searchers in the world who specialize in books, science, other smart information. Keep a list of sites you never heard of.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Columbia University, and Stony Brook University have developed a universal method for producing a wide variety of designed metallic and semiconductor 3D nanostructures—the potential base materials for next-generation semiconductor devices, neuromorphic computing, and advanced energy applications. The new method, which uses a “hacked” form of DNA that instructs molecules to organize themselves into targeted 3D patterns, is the first of its kind to produce robust nanostructures from multiple material classes.

Light particles are particularly suited to transmitting quantum information. Photons can be used to send quantum information through fiber optic cables, to satellites or into a quantum memory element. There, the quantum mechanical state of the photons has to be stored as precisely as possible and, after a certain time, converted back into photons.

Diamonds and rust help unveil 'impossible' quasi-particles

Researchers have discovered magnetic monopoles—isolated magnetic charges—in a material closely related to rust, a result that could be used to power greener and faster computing technologies. Researchers led by the University of Cambridge used a technique known as diamond quantum sensing to observe swirling textures and faint magnetic signals on the surface of hematite, a type of iron oxide. The researchers observed that magnetic monopoles in hematite emerge through the collective behavior of many spins (the angular momentum of a particle). These monopoles glide across the swirling textures on the surface of the hematite like tiny hockey pucks of magnetic charge. This is the first time that naturally occurring emergent monopoles have been observed experimentally.

A highly efficient open-shell singlet luminescent diradical with strong magnetoluminescence properties

Open-shell singlet (OS) diradicals are important building blocks for functional molecular materials, with a large number of pioneering works by researchers advancing their development and applications across various fields. Despite this progress, there remains a lack of research regarding luminescent OS diradicals, hindering their potential use in optoelectronic applications. In fact, the luminescent diradicals are rare chemical species, there are only a few reports to date.

Magnetic field effects (MFE) on the luminescence, i.e., magnetoluminescence (ML) of radicals, hold great promise for developing novel exciton spin manipulation methodologies that are unachievable by conventional closed-shell luminescent molecules.

In 2018, Kusamoto and co-workers first reported MLs in organic radical excimer species, which opened the gate to this field. However, the development of highly luminescent diradicals and the achievement of their efficient single-molecule ML properties continue to be a formidable challenge.

Scientists develop new hydrogels for wound management

Open wounds, whether caused by accidents or from medical procedures like surgery, require proper management to speed up healing and prevent infections. While sutures and staples are common wound closure methods, they can cause secondary tissue injuries, potentially leaking fluids and gases and requiring anesthetics. Tissue adhesive glues are a more attractive alternative but often suffer from toxicity and weak adhesion. Fortunately, tissue adhesive patches offer an innovative solution. They allow precise control of adhesion and mechanical properties through adjustable polymeric compositions. These patches can also deliver drugs directly to wounds, enhancing recovery. While existing adhesive patches containing catecholamines such as dopamine (DA) have shown promise, they face challenges due to slow oxidation and weak bonding with the polymer backbone.
