If you're into #magnetism #nanoscience #spins, check put what @LorenaRosaleny and I have been doing lately:
rosaleny.shinyapps.io/spindyns

DAISY, for "DC/AC Interpretation: Simulate it Yourself" (runner-ups for the backronym: "DC/AC Iterative Simulation Yokefellow", "DC/AC... via Individual Spins? Yeah!", "Dynamical Analysis Instrument for Spins & You" and "Dynamical Analysis for Individual Spins... and Yond")

I find it really cool, but it's mostly for molecular magnetism, a rather niche community...

“There are things done today in electrical science which would have been deemed unholy by the very men who discovered electricity, who would themselves not so long before have been burned as wizards”*…

Climate change continues. There is broad evidence (and consensus) that our environment, thus our ways of life, our livelihoods— indeed, our lives— are threatened. On the heels of a call from Trump to world leaders to abandon the climate fight, followed by a disappointing COP30 conference, it’s easy to be discouraged. But that, of course, is no answer.

Rather, we have to find ways to mitigate the damage that we’ve already locked in, even as we acclerate a transition to clean energy… which begins by (re-)framing and (re-)focusing the challenge. Ember, a clean energy think tank, suggests a candidate that, while it speaks to the moral obligations addressed by one of the models it means to augment/replace, has a more positive orientation…

Humanity is graduating from burning fossil commodities to harnessing manufactured technologies—from hunting scarce fossils to farming the inexhaustible sun, from consuming Earth’s resources to
merely borrowing them.

This isn’t a marginal climate substitution. It’s an energy revolution.

The magnetic centre is the electron: we are revolutionising how we generate, use, and connect
electrons. Solar and wind are conquering electricity supply. EVs, heat pumps, and AI are electrifying major new uses. Batteries and digitalisation are connecting supply and demand.

Three reinforcing shifts. One energy revolution. The electrotech revolution.

At its core, this revolution is driven by physics, economics, and geopolitics. After all, the arc of energy
history bends towards solutions that are leaner, cheaper and more secure.

Short-terms setbacks matter, but fundamentals matter more. And the fundamentals are stacked in electrotech’s favour.

Physics. Electrotech makes a mockery of setting fossils on fire and losing two-thirds of the energy to heat. Electrotech is three times as efficient.

Economics. Technologies get cheaper with scale. Commodities get more expensive the deeper you dig.

Geopolitics. Three quarters of the world is dependent on fossil imports. 92% of countries have renewables potential over 10x their current demand.

Electrotech has grown exponentially for decades. The difference today is that it’s too cheap to contain and too big to ignore. If current exponentials hold for five more years, global fossil demand will fall off its plateau.

Welcome to the Age of Electrotech…

A long and meaty presentation: “The Electrotech Revolution- the shape of things to come,” from @ember-energy.org.

One notes that the electrification that Ember pushes has other advocates, many of whom have been vocal for years; c.f., e.g., Saul Griffin. Still, another voice in the chorus is welcome.

As we plug in, we might send charged birthday greetings to Franz Aepinus; he was born on this date in 1724. A mathematician, scientist, and natural philosopher, he is best known for his research, both theoretical and experimental, into electricity and magnetism. Aepinus’ Tentamen theoriae electricitatis et magnetismi (1759; “An Attempt at a Theory of Electricity and Magnetism”) was the first work to apply mathematics to the theory of electricity and magnetism. And his experiments led to the design of the parallel-plate capacitor, a device used to store energy in an electric field.

“On 13 December, the rare alignment of true north, magnetic north and grid north - known as the three norths - leaves England at Berwick-upon-Tweed, bringing a remarkable three-year chapter to a close.
Magnetic north is monitored using geomagnetic data from the British Geological Survey, combined with Ordnance Survey’s National Grid to track how this alignment shifts over time..."

Teams using our ALMA Observatory have been able to clearly show how magnetism has a pre-eminent role in young star accretion and growth!

The best part is that the lead scientist for that paper is our colleague Paulo Cortés, who apart from doing notable science is also responsible for the scientific acceptance of ALMA software releases!

💠 Can a crystal have different magnetic properties in alternating domains?

👉 Check out in our latest work, how close we can get to such scenario. A "topotactic jump" into a miscibility gap allows #synthesis of metastable crystalline spinel nanoflakes with alternating ferri- and antiferromagnetic domains.

🤝 Many thanks for the fruitful collaboration with wonderful groups at @fhi_mpg_de, #UDE, @TU, @ruhr-uni-bochum.de and #RWTH. We have learned a lot about #magnetism and #TEM.
