Fluorinated gases Puns

Looking at the EPA website, it gives a rundown of the four major greenhouse gases; CO2, Methane, Nitrous Oxide and Fluorinated Gases. It gives a GWP for each. If I multiply out the GWP by % of emissions, or by concentration, or even introducing the lifetime of each in the atmosphere, CO2 seems to have the lowest number of each of the four.

But there are statistics out there stating that CO2 accounts for 80% of the human-caused climate change.

I know I'm missing something. Can someone explain this to me like I'm a Golden Retriever puppy pls?

A shia is using these points to claim imam sadiq received divine knowledge .

He claims he discovered oxygen and hydrogen and says to search : oxygen and hydrogen discovery imam sadiq on google

I have provided the reference he uses and the part about hydrogen is : discovered the presence of hydrogen in water. He had also found out that it was a highly inflammable gas. That is why he said that water could be turned into fire.

And also claims he was right about the 4 main elements in the body as stated below and the 8 which are small and other 8 which are minute in quantity.

Can someone help debunk these claims ?

It was not a miracle of Ja’far as-Sadiq (a.s.) that he moved the mountain which no logical mind would believe, but his greatest miracle was that twelve and a half centuries ago he discovered the presence of oxygen in the air. His father, Muhammad al-Baqir (a.s.), who was also a great scholar, had discovered the presence of hydrogen in water. He had also found out that it was a highly inflammable gas. That is why he said that water could be turned into fire.Ja’far as-Sadiq (a.s.) must have known about the presence of hydrogen in water through his father, but he himself discovered the presence of oxygen in the air.

We do not know if Ja’far as-Sadiq (a.s.) was able to obtain pure oxygen and hydrogen or not. The discovery of these two gases depended upon their separation from air and water. Separation of hydrogen from water was more difficult than separation of oxygen from air. Pure oxygen is available in the air, but pure hydrogen is not available anywhere. That is why hydrogen could not be obtained till sufficient power was developed and water was hydrolyzed. We are surprised how Ja’far as-Sadiq (a.s.) and his father were able to discover hydrogen, which is a colourless, odourless and tasteless gas and does not exist freely in nature. They could not have identified this gas and found out its properties without separating it from water through the process of hydrolysis, which was impossible without a strong current of electricity.

The Imam said that while all human beings were made from the earth, which was a known fact, he also said that whatever is in the earth is also in the human body, but all elements are not in the same proportion. Four elements are in very large quantity, eight elements in smal

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Generated a star system for an RPG and I ended up with an iceworld with no water ... I looked at the probable temperature based on its location based on the star (similar to ours) and it's around where Pluto is, 50 Kelvin, so I looked for gases that could be frozen there. (it's also a vacuum planet, no atmo)

I found that fluorine would be frozen there and read up and read

> Fluorine is a corrosive pale yellow gas. It is highly reactive, participating in reactions with virtually all organic and inorganic substances. Fluorine is the most electronegative element. Metals, glass, ceramics, carbon, and water will burn with a bright flame in fluorine.

Makes me wonder, would that happen when it's frozen, like you took a walk on the fluorine ice, would your space suit have serious problems if you didn't make it from the right materials?

Do your worst!

I'm surprised it hasn't decade.

Don't you know a good pun is its own reword?

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!

I guess I'd better post this in r/lasers but since a year ago a redditor (u/Caver_Coder ) was looking for a manual and made a similar thread here about dye laser restoration, I'll post it in r/chemistry https://www.reddit.com/r/chemistry/comments/dputw3/coherentlambdaphysik_fl3002_documentation/

I found myself in the same kind of situation, though a little bit more complicated. FL3002 is a dye laser, number "2" in "3002" means that it is the double cuvette laser with master oscillator- power amplifier (MOPA) scheme. It is assumed to be pumped by pretty high energy ~100-500 mJ UV light. Such a pump can be generated by either excimer lasers (308 nm XeCl or 351 nm XeF) or very high energy frequency tripled Nd:YAG laser (355 nm).

I accidently got both the pump and dye set, the combination of an ancient Lambda Physik LPX210i excimer laser and FL3002 dye laser, both 1989 vintage.

Lambda Physik LPX200 excimer laser. This pic is from the internet, cause mine is disassembled right now, see the pictures below...

FL3002 Dye laser

The history of this lasers is quite hilarious, these were exported to the Soviet Union, but the person who received them immigrated to the United States shortly after the USSR disbanded. Those things remained mostly unused for the last 3 decades except for the few years between 2000 and 2010 when one of my colleagues used the LPX for his research. When I powered up LPX200 the shot count was ~12kk shots, assuming it was operated at 100Hz means that it worked for ~approximately 33 hours over the last 32 years. I suppose the dye laser has been operated even less than LPX. I even doubt, that it was operated after it has been shown to work by Lambda Physik installation engineers.

Funny thing is that it was almost completely impossible to purchase any foreign equipment back in the Soviet era. All the dollars required for imports where strictly controlled by the government and such a purchase had to be approved on a ministry level. I suppose this lasers were bought because the director of the institute was the member of the supreme co

Because she wanted to see the task manager.

But that’s comparing apples to oranges

PART 1 is here tl.dr. was slowly restoring the giant ancient Lambda Physik LPX200 ultraviolet excimer laser in my spare time.

I'll keeps this pic from the post number one.

Situation has changed dramatically since the original posting. A research proposal that I've written in the early march was approved and I gonna receive a small funding of ~20.000$/year for 2 years. This sum is enough to acquire the necessary optics, gases, dyes and solvents to run the devices, but the drawback of this situation is that I'll have to publish at least 1 paper in decent journal by the end of the project first year period (30 june 2022), and 2 more papers the next year. Taking into account that publishing process takes no less than 2 months to happen (regularly 3 to 4 or more), I need to make this lasers work, make the experiments, write the manuscript by the end of the January. And if I don't publish this papers, basically my research career will get a little bit screwed. In that case I'll be banned for making proposals for the next 3 years and after that every project reviewer will blame me for having poor project management experience XD

Anyway, it is a very high risk/very high gain and lot of fun research that may lead us to some outstanding results. So here we are, "the professionals". We = me and two undergraduate ladies that will write their Master thesis in our lab under my supervision.

By the end of year one we have to make a couple of lasers work on Krypton Chlorine, 222 nm wavelength. KrCl is one of the excimers that were abandoned in 1980ies because of their seemingly low efficiency and power. Basically they competed with way more effective shorter wavelength ArF (193 nm) and longer wavelength KrF (248 nm) lasers and they lost this competition. They disappeared from commercial catalogues and laser manuals in late 80ies/early 90ies and today most people, even those who work with excimers don't even know that this lasers can work on 222 nm wavelength. About ten years ago a some of my colleagues from another Institute had shown on a very good home-made excimer laser that in certain conditions KrCl actually is a very decent gain, no worse than ArF/KrF, but it requires specific pump power a couple of time higher than any othe

Heard they've been doing some shady business.

but then I remembered it was ground this morning.

Edit: Thank you guys for the awards, they're much nicer than the cardboard sleeve I've been using and reassures me that my jokes aren't stale

Edit 2: I have already been made aware that Men In Black 3 has told a version of this joke before. If the joke is not new to you, please enjoy any of the single origin puns in the comments

BamBOO!

They’re on standbi

Two muffins are in an oven, one muffin looks at the other and says "is it just me, or is it hot in here?"

Then the other muffin says "AHH, TALKING MUFFIN!!!"

A play on words.

Here’s what No One tells you about Comprehensive Utilization Of Aluminum Dross

Here’s what No One tells you about Comprehensive Utilization Of Aluminum Dross

China electrolytic aluminum industry is developing rapidly, and its output level has been leading the world for many years. In 2019, the output of China electrolytic aluminum reached 35.04 million tons.

The annual aluminum dross generated by electrolytic aluminum, aluminum processing, and secondary aluminum was more than 4 million tons, and the historical accumulation was more than 10 million tons. According to different production processes, the aluminum content in aluminum dross will also vary according to the source, usually from 15 to 70%.

According to statistics, the amount of aluminum dross produced generally accounts for about 7%-12% of the recycled aluminum output, of which metallic aluminum accounts for 30-40%, which is quite considerable. In addition to aluminum, aluminum dross also contains a part of alumina, which is also valuable.

Aluminium dross is a mixture of metallic aluminium and non-metal part mostly aluminium oxide, and aluminium dross is a valuable by-product of any aluminum smelter or aluminium foundry, which still contains 10%-30% aluminum and 20%-40% alumina. Unfortunately, many factories do not realize the value of aluminum dross, and abandon it casually, which not only pollutes the ecological environment, but also loses the economic benefits of the company.

Aluminum dross recycling is a wise choice for aluminum enterprises under the influence of energy-saving and emission reduction.

The amount of aluminum dross generated is closely related to the composition of scrap aluminum, melting and casting technology, agent composition, and temperature in the melting furnace. Generally speaking, the higher the oxidation degree of scrap aluminum, the larger the surface area of the scrap aluminum material, and the more inclusions, the greater the amount of aluminum dross will be.

Aluminum dross is generated in all the processes of molten aluminum, mainly including: primary aluminum production (electrolytic aluminum), aluminum alloy production, scrap alumi

Or would that be too forward thinking?
