Too bad that I missed the DPG this year. But thanks to my group we still made a great presence. @rjpRoman , @SANDIP99113487 and Toni Hache made excellent presentations on our ongoing works on NV-magnetometry in #DPG2024 yesterday. #proudpi

My student @SANDIP99113487 and postdoc @rjpRoman having great time at the WE-Heraeus seminar at Bad Honnef organised by @WillkePhilip, @LaertePatera and DJ Choi. Unfortunately I couldn’t make it in person, but I certainly look forward to see you all virtually tomorrow at my talk!

Super happy! The first ODMR signal from our homebuilt scanning NV setup with our unique design of MW on the tip! Still a lot of things to improve. But first-time comes only once 😃 so @rjpRoman @dineshkpinto and my new student Sandip! Very very well done :)

@DaniBeckman @zeiss_micro Não entendo muito coisa. Mas gosto muito das imagens. Acho interessante:-)

Robert Oppenheimer otorgó a la humanidad un poder inmenso para luego ser castigado por esa ofrenda. El libro «Prometeo Americano», (@debatelibros) y la reciente película de Christopher Nolan inciden en la figura de este Prometeo del s. XX.

This week, scientists have been STUNNED by the possible discovery of room-temperature superconductivity.

IF it is true, humanity might have passed a HUGE milestone.

The impact will be WAY bigger than the combined impact by ChatGPT, artificial AI and anything else you’ve heard of.

In #science, this discovery is much bigger than any graphene, Li-ion batteries, observation of black holes, and even Higgs boson.

▫️

In a long run, the consequences can be bigger than the outcome of industrial revolution and discovery of nuclear reactions and energy. It will deeply transform the humanity.

▫️

I’m putting a list of things that come to my mind. However, there are many more points in reality. Some changes will be so "core" that we can't even foresee them today.

1⃣ Electric vehicles and levitating high-speed trains will benefit immensely. We will see a drastic increase in energy efficiency. Putting it together with high-efficiency superconducting motors, I wonder - "Gas stations will become obsolete?".

2⃣ Energy Storage and Transmission. First, we will see the emergence of LOSSLESS electrical grids with extremely long distance of electricity transmission. Second, a RT superconducting coil is a “perfect battery”. It can store and release a lot of energy with 100% cycling stability and ulta-slow “self-discharge”. It will change everything, from power grids to space shuttles.

3⃣ Computers!!! We will see the emergence of ultrafast, low-energy-consuming computing devices. Stable quantum computing at RT may become a perfectly feasible thing. Overall, this will revolutionize the ways we build computers and devices.

4⃣ Extraordinary sensors in everyday life. Currently, regular superconducting sensors (e.g. near-IR single-photon detectors, or magnetic field sensors) need very low temperatures and are used in very specific/expensive domains. RT superconductors will bring them to our houses, changing the technologies around us forever.

5⃣ Super-cheap MRI machines for medical diagnostics. MRI relies on superconductors, but they can operate at very low temperatures, making the instruments super-expensive. With RT superconductors, they will become compact and cheap. New era for accessible medical diagnostics!

6⃣ High-efficiency and powerful motors. When conventional electric motors incorporate superconducting materials, it will make them a LOT more efficient. Reduced energy consumption + smaller size will revolutionize the industrial machinery and appliances. I am sure that airplanes with electric propulsion will finally become possible.

7⃣ Nuclear fusion may become viable (and controllable) because superconductors are one of the key ingredient.

As you see, such a discovery will change the world as we know it.

▫️

Now, the key question is - can someone reproduce these results?

As far as I see, many groups have jumped into this topic.

Let’s wait for the outcome!

La gente te dice que debes arriesgar, que debes ser impulsivo y que debes lanzarte como loco a hacer cosas. Si no lo haces, te dicen aburrido. Difiero de eso, hay que tener mucha prudencia antes de tomar una decisión, para eso hay que prepararse conociendo lo que su inconsciente esconde, tomando en cuenta las creencias psicológicas en las que se esta basando para tomar esa decisión y sometiendo a juicio esas creencias, porque a veces nos dejamos llevar por creencias sociales o familiares que no son correctas y nos alejan de lo mas importante: nuestra paz.
