The exposed skin.

The beautiful contrast of their skin tone.

The endless hearts.

And once again,

And most important of all,

The vulnerability.

The soft passion.

The absolute

…agency. 💜

One heart wasn't enough...♡

Every time I have to study electrochemistry something inside me dies. I love chemistry, okay? Truly it's my biggest passion. General, inorganic, coordination, analytical, spectroscopy, thermodynamics? Yes please! Nuclear, kinetics, quantum? Not necessarily my favorite but still cool. Organic? I detested it but I was still pretty good at it. But electrochemistry is the bane of my existence. I hated it in analytical, I hated it in pchem, now I hate it in instrumental analysis. I suppose we all just need to have that one aspect of our beloved field that makes our skin crawl ¯\_(ツ)_/¯

How to make plasma in the microwave using a grape (don't)

For those of you who don't want to watch the whole video (I recommend watching it, if only for the guy's extremely blase attitude to fire and poisonous gas in his microwave, here is just the plasma part:

And the crazy thing is, even though people have been making videos of this for over 20 years, scientists didn't actually know why it happens until 2019.

Basically, plasma is what happens to matter when it is superheated enough that electrons start to come loose from the atoms they belong to and just create a soup of charged particles. This Science article explains well how this effect is created by a halved grape connected by a thin strip of skin:

"Water-heavy grapes trap the wavelengths of energy microwave ovens emit because the waves are roughly the same size as the diameter of grapes. That energy starts charging up electrolytes inside the fruit, which then flow from one half of the grape to the other—using the strip of skin like an electrical wire and gaining energy as they go. The current quickly burns through the skin, causing the charged electrolytes to try to jump from one half of the grape to the other, supercharging the surrounding air into a bright flare of plasma—the same light-emitting state of matter responsible for the sun's rays and fluorescent lighting."

You can see in these energy diagrams of the microwaved grapes that when the grape halves are moved closer together, alllllll of the energy that is normally distributed throughout the two grape halves condenses down into an extremely small area between them to form a hotspot of radiation. The energy of this area is so great that it can heat the surrounding gas enough to turn it into plasma.

All this to say that this is a super cool quirk of science that you definitely should NOT try at home (the scientists doing the experiment to find out why this happened destroyed 12 different microwaves in the process lol)

STOP IF WILL IS WITH MIKE AND EL AT THE RADIO STATION PLACE AND THE STRANGER THINGS BROADCAST CHANNEL POSTED BOOKS ABOUT ELECTRICITY AND LIGHTS AND RADIOS WHICH I WROTE IN A POST ABOUT HERE AND ONE OF THE BUILDINGS THEY’RE FILMING AT IS CALLED 5000 WATTS OR SOMETHING LIKE THAT WHICH HAS TO DO WITH LIGHTING AND WILL WAS ABLE TO FIGURE OUT HOW TO COMMUNICATE FROM THE UPSIDE DOWN WITH LIGHTS AND GOING BACK TO S2 THEY USED THE RADIO TO PLAY MUSIC TO COMMUNICATE WITH WILL AND WE KNOW MUSIC PLAYS A BIG ROLE IN BEING PROTECTED BY VECNA AND EL CAN ALSO COMMUNICATE WITH RADIO FREQUENCIES AND SOMEHOW ALL THIS TIES INTO MIKE BEING THERE TO SAVE WILL ONCE AGAIN AND THAT LEADS TO BYLER ENDGAME

Modern power cells could maintain stability by using ionic bonds to control their electrical charge, but this is illegal as it would result in a salt and battery.

"It may sound surprising, but when times are tough and there is no other food available, some soil bacteria can consume traces of hydrogen in the air as an energy source.

In fact, bacteria remove a staggering 70 million tonnes of hydrogen yearly from the atmosphere, a process that literally shapes the composition of the air we breathe.

We have isolated an enzyme that enables some bacteria to consume hydrogen and extract energy from it, and found it can produce an electric current directly when exposed to even minute amounts of hydrogen.

As we report in a new paper in Nature, the enzyme may have considerable potential to power small, sustainable air-powered devices in future.

Bacterial genes contain the secret for turning air into electricity

Prompted by this discovery, we analysed the genetic code of a soil bacterium called Mycobacterium smegmatis, which consumes hydrogen from air.

Written into these genes is the blueprint for producing the molecular machine responsible for consuming hydrogen and converting it into energy for the bacterium. This machine is an enzyme called a “hydrogenase”, and we named it Huc for short.

Hydrogen is the simplest molecule, made of two positively charged protons held together by a bond formed by two negatively charged electrons. Huc breaks this bond, the protons part ways, and the electrons are released...

The molecular blueprint for extracting hydrogen from air

With Huc isolated, we set about studying it in earnest, to discover what exactly the enzyme is capable of. How can it turn the hydrogen in the air into a sustainable source of electricity?

Remarkably, we found that even when isolated from the bacteria, Huc can consume hydrogen at concentrations far lower even than the tiny traces in the air. In fact, Huc still consumed whiffs of hydrogen too faint to be detected by our gas chromatograph, a highly sensitive instrument we use to measure gas concentrations...

Enzymes could use air to power the devices of tomorrow

It’s early days for this research, and several technical challenges need to be overcome to realise the potential of Huc.

For one thing, we will need to significantly increase the scale of Huc production. In the lab we produce Huc in milligram quantities, but we want to scale this up to grams and ultimately kilograms.

However, our work demonstrates that Huc functions like a “natural battery” producing a sustained electrical current from air or added hydrogen.

As a result, Huc has considerable potential in developing small, sustainable air-powered devices as an alternative to solar power.

The amount of energy provided by hydrogen in the air would be small, but likely sufficient to power a biometric monitor, clock, LED globe or simple computer. With more hydrogen, Huc produces more electricity and could potentially power larger devices.

Another application would be the development of Huc-based bioelectric sensors for detecting hydrogen, which could be incredibly sensitive. Huc could be invaluable for detecting leaks in the infrastructure of our burgeoning hydrogen economy or in a medical setting.

In short, this research shows how a fundamental discovery about how bacteria in soils feed themselves can lead to a reimagining of the chemistry of life. Ultimately it may also lead to the development of technologies for the future."
