Pursuing the Ultimate - A Sunresin Perspective on Purity

In nature, substances appear in the form of mixtures. This rule applies to our most common, simple, and indispensable sunlight, air, and water. The sunlight splits into seven colors namely violet, indigo, blue, green, yellow, orange, and red. Air is mainly composed of nitrogen, oxygen, Β argon, carbon dioxide and some other substances. The water we consume in our life also dissolves many ions such as calcium, magnesium, sodium, potassium, carbonate, bicarbonate, sulfate, and chloride ions.

However, in industrial applications, we only need and use a specific property of a specific substance, that leads to the need to separate the specific components from the mixtures. In order to maximize the use of the specific component, the rule is simple, that’s basically β€œThe Purer The Better”. Therefore, the development history of industrial civilization is accompanied by the progress of separation and purification technologies.

The wave of new technological revolutions set off in the second half of the 20th century is changing human life in unprecedented ways. Among them, the most noticeable are information technology and modern biotechnology, whose rapid development has led to much higher requirements for the separation technologies.

In the semiconductor industry, there is the so-called "Moore's Law", according to which the number of transistors in a dense integrated circuit (IC) doubles about every two years, and the performance of the processor will also be doubled. In other words, for the same function to be realized, the space is reduced by half. Due to the continuous improvement of the precision of "lithography", the component density and circuit density on the silicon chip have been greatly improved. With the increase in density, more stringent requirements have been placed on the material performance as the bearer of integrated circuits or chip space. This improvement of material properties is by improving purity. For the tens of billions of transistors on a chip the size of a fingernail, any small purity defect may lead to irregular heat dissipation, conductivity, or short circuits that mean disasters for the chip.

The purity of electronic grade polysilicon is required to reach 99.999999999%. Higher purity means more complicated production and refining processes. The 11N purity is equivalent to the total impurity of

Is Solar Energy Sustainable?

As long as there are humans on this world, the sun will shine. As a consequence, from our viewpoint, solar energy seems to have a limitless supply.

The sun supplies more total energy to the Earth every second than people use in a year. Furthermore, solar energy creates substantially less pollution than "dirty" electricity when it is created or consumed. By growing solar power and lowering reliance on fossil fuels, global carbon emissions might be drastically reduced.

Because sunlight is not extracted from the ground, it has a smaller environmental impact than fossil fuels. Extraction of fossil fuels might be difficult. In 2010, BP's deep-sea oil drilling disaster released 3.19 million barrels of oil into the Gulf of Mexico, inflicting environmental harm to marine ecosystems. Coal mining in Appalachia has destroyed some of the world's oldest mountains while also wreaking havoc on the health of local people. Solar energy, on the other hand, has a negligible influence on the environment.

Is solar energy good for the environment?

Solar power is almost as clean as it gets. There is no such thing as a 100% clean energy source (yet!). When the sun's rays are utilized to create electricity, they do not release any hazardous substances, unlike fossil fuels. There are no carbon emissions or pollutants when the sun's power is harnessed for electricity, and nothing harms the environment locally or globally.

However, photovoltaic panels, which convert light into electricity, must be built. This uses up resources like energy and raw materials, and some of the processes have hazardous side effects. Silicon tetrachloride is a well-known example of these byproducts, which is formed when polysilicon is made from metallurgical-grade silicon. If it is spilled, it will react with water to make hydrochloric acid, acidifying the environment and releasing harmful fumes.

Despite the fact that technology exists to recycle and render such waste harmless, not all businesses are prepared to invest in the costly machinery. Better rules, incentives, and laws may help to solve this problem.

While this is true, solar energy is still much more ecologically friendly and clean than nonrenewable forms of electricity. As a consequence, it is one of the most feasible clean, renewable energy choices available. It's also possible that in the not-too-distant future, we'll be able to entirely green t

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

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.

Just because it's a joke, doesn't mean it's a dad joke

Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.

THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB

Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"

I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual

So check out r/jokes for all types of jokes

r/unclejokes for dirty jokes

r/3amjokes for real weird and alot of OC

r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes

Punchline !

Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub

Edit 2: don't touch the thermostat

Dropped my best ever dad joke & no one was around to hear it

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!
