The flow of some unique liquid
fluids are a necessary part of everyday life after all without water you couldn't live and without chocolate syrup well what would be the point but have you ever noticed that not all liquids behave the same in fact some of them do some pretty bewildering stuff under the right circumstances and even after decades of research scientists are no closer to understanding why one question about strange fluids may have finally been answered thanks to some glass beads and i always love saying this laser beams all liquids we encounter in the real world can basically be boiled down to one of two kinds they're either newtonian or non-newtonian newtonian fluids are pretty easy to grasp mean not literally in some cases a newtonian fluid like water would squirt right out of your hand but chocolate syrup is also newtonian even though it would slowly dribble out of your hand maybe as you frantically lick your palm to get all that chocolatey goodness before it drips away it's not just me right uh anyway in other words chocolate syrup is much more viscous than water viscosity is a measure of a fluid's resistance to flow it's basically the friction between molecules in a fluid the higher the viscosity the slower the flow a newtonian fluid obeys newton's law of viscosity which means its viscosity is constant it doesn't change when a force is applied to it non-newtonian fluids on the other less sticky hand do change their viscosity which can lead to some pretty zany shenanigans there are different subcategories of non-newtonian fluids depending on how their viscosity changes there are dilatance whose viscosity increases as force is applied and examples of dilatance include quicksand silly putty and the cornstarch water mixture known to first grade classrooms as oobleck the tiny cornstarch particles in oobleck can flow freely with the water molecules if you gently dip your fingers in but it you give it a good smack the cornstarch locks up giving oobleck a surprisingly solid character you could straight up run across a swimming pool if you dumped enough cornstarch in it but there are vandalism laws so you know some fluids get more viscous when force is applied but the opposite can also be true ketchup is in a category of non-newtonian fluids called pseudoplastics when no force is applied it just sits there not doing anything but when you give the back of a bottle a whack the viscosity decreases and the ketchup comes out till R20% inside the sauce at a molecular level what's happening is long chains of atoms called polymers get tangled together and they hold fast but when they're smacked or shaken they stretch out and align allowing the gooey red paste to slide around hopefully onto your french fries but probably a little on your pants too still there are many more weird non-newtonian behaviors scientists don't have answers for they may have just solved one riddle that stood for over 50 years the problem was first noticed in the 1960s when engineers were attempting to extract oil from the ground with fluid that contained long chain polymers pumping these so-called pressure fluids into the ground below a certain rate worked fine but pumping them faster would cause them to become much more viscous, the fluids would only behave this way when flowing through the microscopic spaces between soil when not confined to the twisty windy paths in a porous medium the fluid's viscosity would actually drop as more forces applied like ketchup for a while scientists thought that maybe the polymers were clogging up the pores in the soil but that couldn't explain how the fluids flowed easily when the flow rate dropped again it wasn't until a new study was published in late 2021 that scientists think they might have cracked it part of the problem they've had is soil and other porous media aren't see-through so it's kind of hard to tell what's going on down there to solve this they created a custom medium out of glass beads and they concocted a polymer solution with the same refractive index as the glass meaning the liquid and solid would both bend light exactly the same way to see the windy paths fluids would fall out in the spaces between the beads the researchers added a red dye to the solution that would give off a certain wavelength of light when hit with a laser to visualize how the fluid was moving they added tracer particles that would emit a different color when excited by another laser with this extremely complicated setup in place they observed the fluid flowing at different rates and found that the long polymers in it started tumbling around as the fluid moved faster this movement pushed on other nearby molecules in the liquid and caused a phenomenon called elastic turbulence creating eddies and slowing the whole fuid down. The researchers think this new understanding of why pusher fluids suddenly become so viscous could be useful for purifying groundwater aid in the development of new polymer containing solutions that can forcewater through rocks trapping contaminants in the process but there's more work to be done because elastic turbulence itself isn't fully understood maybe that'll be the next riddle solved or maybe first we'll finally get an answer for why people like ketchup on scrambled eggs granted that has nothing to do with its non-newtonian properties but it's still something i just can't wrap my head around.

How to die black to blue jean with bacteria
-How do we actually make that impact on the fashion industry by going after the 70 to 80,000 metric tons of indigo that are produced annually and the countless other dyes and colorants that are utilized in a great number of other industries? Thus, our genuine concentrate right currently is truly putting our answer into the full modern assembling scales so that we can begin to convey material into the design business, and ideally. be the next pair of jeans worn by everyone. Indigo is only one part of the enormous supply chain that produces billions of pairs of jeans annually. Customers are largely unaware of this world. -I believe that every consumer, as well as we as a society, would greatly benefit from just a little bit more awareness about the materials that are used to make our clothing, in the same way that people pay attention to the ingredients that are in our food. Naturally, businesses and regulators also have a role to play, and voluntary efforts are being made to eliminate hazardous chemicals from the production of apparel. Additionally, new legislation is being considered with the intention of increasing transparency in the fashion supply chain. We need to regulate this industry in order to turn it around. In the oil and gas industry, we don't just talk about innovation. We discuss the necessity of regulation. - [However no part of this implies you really want to go out also, purchase the cleanest, most practical pair of pants out there. It's a wonderful product, in my opinion. It tends to be a slow design. On the off chance that you esteem it, you can purchase a pair of jeans, and ideally, you can wear them for the following 10 years. I just hope that fashion does not change too quickly. - Along these lines, while we sit tight for this transformation in denim innovation to show up, we can continuously purchase less pants. keep wearing the pants we currently own, wash them less, and give them when we're finished utilizing them. Before donating them, you can wash them. Oh, hands of smurfs. that's right, I'll rinse that. Continuously ensure your gloves fit firmly.The vast majority of us can't envision looking into our storeroom and not seeing a couple of these, Levis. You've got dad jeans, bootcuts, and the skinny hipster type. The indigo dye, which gives our jeans their blue color, is something that almost all of them share. Sadly, the color we use today is really filthy. Also, because we make a lot of jeans, that one process has an effect. However, some people are reimagining how we make indigo dye so that our jeans might be a little cleaner in the future. Jeans are a fashion staple. so that they are in the closet of everyone. As a result, I believe they make an excellent case study. It is estimated that billions of pairs of jeans are produced annually. In addition, over 70,000 tons of indigo are produced to give the jeans their iconic blue hue. Indigo is actually the key to the classic faded look. -That's what makes jeans so great: as you wear them, this fades into something like a beautiful color. Therefore, only indigo can be used. Actually, there are two kinds of indigo dye—natural and synthetic—that can produce that fade. People have been utilizing the normal stuff that comes from Indigofera plants for 1,000s of years. However, synthetic indigo dye was created in 1897 by German chemists for industrial production. Almost all genes are now dyed using synthetic indigo. Artificially, it's indistinguishable from plant-based indigo color. Therefore, the final product is the same, but the production process necessitates a noxious mixture of toxic materials and fossil fuels. The issue is what happens when synthetic indigo dye is used to dye billions and billions of pairs of jeans, just like formaldehyde, hydrogen cyanide, aniline, and sodium amide. As a result, numerous chemicals are used in the dying process. There is the indigo dye itself, but there are also additives that make it possible for the dye to dissolve in water. We are making use of sodium hydrosulfite and soda ash in this instance. which, as stated in our dying kit, could be harmful if used improperly. So on a modern scale, these added substances can be unsafe to individuals working in material manufacturing plants, particularly on the off chance that the plant no longer has anything to do with spec, or on the other hand they don't approach PPE. In textile workers, chemical exposure has been linked to respiratory problems, skin problems, and even skin cancer. Thus, I'm not in a material processing plant, but rather it is breezy. and it's safer to be safe than to fail. Here, we only need to use clean water to remove all of the chemicals after a few dips. However, not all jeans are made equal. Contaminants such as formaldehyde and aniline can be present in some finished products. Along these lines, presently we completed the process of kicking the bucket everything. We should simply securely discard this by flushing it straight down the channel. This is only a five-gallon container, yet, however much 280,000 tons of material colors end up as wastewater every year, Furthermore not every last bit of it is discarded appropriately. especially in places where the industry is unregulated or there are poor environmental protections. - Assuming you go to any plant urban areas delivering these material items, the streams are dark from the discharge emerging of these production lines. That wastewater can mess up sea-going environments, dirty drinking water, furthermore, even end up in food becoming close by. - Furthermore, I know that a ton of denim laundries, denim brands they're expecting some sort of ipn of advancement where they can move away from manufactured indigo. However it's not all terrible information. There are numerous efforts to improve this process from beginning to end, including water reduction and safer finishing methods. One company is aiming for that beloved blue color. -Thus, this is a standard kind of the atomic science lab. In order to introduce DNA into our microbial host, most of our cutting and pasting occurs here. A company called Huue uses sugar instead of fossil fuels to make indigo dye. Sequencing the DNA for indigo compounds begins with an indigo plant. Microbes are programmed with this genetic code, and they produce precisely those indigo molecules. -And you can kind of see that some of them are producing a lot of dark blue color and others are producing much less, so you can put the strains that are doing the best in a shaker flask so that they can multiply. Those societies develop until there's sufficient togo into a bioreactor. We either have a different strain of our microbe in each of these reactors, or we have the same strain but in different media or growth conditions. We have some control over things like how quick they're blending. Furthermore, how much oxygen is going into the stock. - The colors are then broke down and cleaned before the testing stage. Therefore, even after the bacteria have grown and produced the indigo dye, the mixture of dye, bacteria, and the media in which it has actually been grown remains. We focus on getting rid of the dye and ensuring that the finished product is identical to what synthetic indigo users would expect. The concentrated dye is first added to water. - The fabric is now passing through these rollers, Thus, here's the principal pass of color. -Huue is still largely in the R&D stage. Additionally, it is not the only team attempting to resolve this issue. Additionally, it is not the only team attempting to resolve this issue. DyStar, one of the main makers of manufactured indigo, has made its bite of the dust more secure for laborers and simpler to clean. Others have made indigo free of explicit foreign substances like aniline. Huue is beginning with indigo, but they have much higher goals. -How would we truly make that effect into the style business by truly following the 70 to 80,000 metric lots of indigo that are made consistently, and afterward past that the a huge number of metric tons of different colors and colorants that are utilized in such countless different ventures. Thus, our genuine concentrate right currently is truly putting our answer into the full modern assembling scales so that we can begin to convey material into the style business, and ideally,. be the next pair of jeans worn by everyone. Indigo is just a single part, allbeit a colossal one, in the enormous production network that produces billions of pants every year. Customers are largely unaware of this world. -I believe that every consumer, as well as we as a society, would greatly benefit from a little bit more awareness regarding the materials that are utilized in Qur clothing, similar to how people pay attention to the ingredients that are utilized in the food that we consume. Naturally, businesses and government authorities also have a role to play, and voluntary efforts are being made to eliminate hazardous chemicals from the production of apparel. Additionally, new legislation is being considered with the intention of increasing transparency in the fashion supply chain. We need to regulate this industry in order to turn it around. We don't just talk about innovation when it comes to the oil and gas industry. We discuss the requirement for guideline. However no part of this implies you really want to go out furthermore, purchase the cleanest, most economical pair of pants out there. It's a wonderful product, in my opinion. It might move slowly. You can purchase a pair of jeans if you value them and hope to wear them for the next ten years. I'll just hope that fashion doesn't change too quickly. Therefore, while we wait for this revolution in denim technology to occur, we always have the options of purchasing fewer pairs of jeans, continuing to wear the jeans we already own, washing them less frequently, and donating them when we are finished using them. Before donating them, you can wash them. Continuously ensure your gloves fit firmly. The majority of us can't envision looking into our storage room and not seeing a couple of these pants. You've got dad jeans, bootcuts, and the skinny hipster type. The indigo dye, which gives our jeans their blue hue, is something that almost all of them share—6lB/S 27%. Sadly, the color we use today is really messy. Also, because we make a lot of jeans, that one process has an effect. However, some people are changing how we make indigo so that our jeans might one day be a little cleaner. Jeans are a wardrobe staple because they are so iconic. So I believe that's why they make excellent case studies. Consistently, it's assessed that billions of matches of pants are made, and to give them that famous blue shade, north of 70,000 tons of indigo are created also, What's more, that indigo is really key to that exemplary blurred look. -That's what makes jeans so great: as you wear them, this fades into something like a beautiful color. Therefore, only indigo can be used. There are really two sorts of indigo color that can deliver that blur, normal and engineered. Indigofera plants' natural products have been used by humans for thousands of years. However, synthetic indigo dye was created in 1897 by German chemists for industrial production. -Nowadays, practically all qualities are colored with engineered indigo color Synthetically, it's indistinguishable from plant-based indigo color. - In this way, the finished result is something similar. However, toxic materials like formaldehyde, aniline, sodium amide, and hydrogen cyanide are required for the production process. The issue is what happens when you dye billions of pairs of jeans with synthetic indigo dye? As a result, numerous chemicals are used in the dying process. You have the dye itself, indigo. Additives, on the other hand, make it possible for the indigo to dissolve in water. In our case, we are making use of sodium hydrosulfite and soda ash, both of which are listed in our dying kit as potentially hazardous if used improperly. So on a modern scale, these added substances can be destructive to individuals working in material manufacturing plants, particularly on the off chance that the production line no longer doesn't depend on spec, or on the other hand they don't approach PPE. In textile workers, chemical exposure has been linked to respiratory problems, skin problems, and even some types of cancer. In this way, I'm not in a material production line, but rather it is blustery, what's more, preferable to be protected over heartbroken. Here, we only need to use clean water to remove all of the chemicals after a few dips.In any case, not all pants are made similarly. some finished items can contain impurities like formaldehyde and aniline. Thus, we have now completed dying everything. All that remains for us to do is dispose of everything in a secure manner by flushing it down the drain. Even though this is only a five-gallon bucket, every year up to 280,000 tons of textile dyes end up in wastewater. Not all of it is disposed of properly, especially in places where there aren't good environmental protections. or on the other hand the business is unregulated. If you go to any factory city that makes these textile products, the effluent from these factories turns the rivers black. That wastewater can harm aquatic ecosystems, pollute drinking water, and even enter nearby agricultural crops. Additionally, I am aware that numerous jeans washes and jeans brands are hoping for some kind of breakthrough that will enable them to move away from synthetic indigo. However, this isn't all bad news; numerous efforts are being made to improve this process from beginning to end, including reducing the amount of water used and using safer finishing methods. One company is aiming for that blue color that we all adore. This is a pretty typical molecular biology laboratory. In order to introduce DNA into our microbial host, most of our cutting and pasting occurs here. -Huue is an organization that makes indigo color from sugar rather than petroleum derivatives. They start with an indigo plant and succession the DNA for indigo mixtures. Microbes are programmed with this genetic code, and they produce precisely those indigo molecules. Additionally, you can see that some of them are producing a significant amount of dark blue color. And some of them are producing significantly less, so you put the strains that are performing the best in a shaker flask to multiply. Those societies grow until there's sufficient to go into a bioreactor. We either have a different strain of our microbe in each of these reactors, or we have the same strain but in different media or growth conditions. We have control over things like how quickly they stir and how much oxygen enters the broth. - Prior to the testing phase, the dyes are then analyzed and purified. -In this way, after the microorganisms have sort of developed also, delivered the indigo color, it's still sort of this combination of microscopic organisms, and color, also, the media that it's really been filled in. We work on purging out the color and ensuring that the last color stuff is precisely exact thing a manufactured indigo client would anticipate. The concentrated dye is first added to water. The fabric is currently passing through these rollers. So, the first dye pass is here. Huue is still in the research and development stage. Additionally, it is not the only team attempting to resolve this issue. DyStar, a major manufacturer of synthetic indigo, has improved the safety and ease of cleaning of its die. Others have produced indigo that does not contain particular contaminants like aniline. Huue is going to start with indigo, but they have bigger goals in mind. How can we really make an impact on the fashion industry by going after the 70 to 80,000 metric tons of indigo that are produced annually and the many thousands of other dyes and colorants used in so many other industries? Therefore, our primary focus right now is putting our solution through its entirety on industrial manufacturing scales so that we can, hopefully, begin delivering fabric to the fashion industry. be the next pair of jeans worn by everyone. Indigo is only one part of the enormous supply chain that produces billions of pairs of jeans annually. Customers are largely unaware of this world. I think we, as a general public, would truly benefit, like each buyer, would benefit from simply having somewhat more mindfulness about the materials that are going into our garments similarly that individuals focus to what fixings go into the food that we devour. Naturally, businesses and regulators also have a role to play, and voluntary efforts are being made to eliminate hazardous chemicals from the production of apparel. Additionally, new legislation is being considered with the intention of increasing transparency in the fashion supply chain. We need to regulate this industry in order to turn it around. In the oil and gas industry, we don't just talk about innovation. We discuss the necessity of regulation. However, none of this necessitates purchasing the cleanest and most environmentally friendly pair of jeans. -I love denim. It's a wonderful product, in my opinion. It might move slowly. You can buy jeans if you value them and hope to wear them for the next ten years. I just hope that fashion does not change too quickly. As a result, we always have the option of purchasing fewer jeans while we wait for this technological revolution in denim. Wear the jeans we already have, lessen the amount of time we spend washing them, and then give them away. You can wash them before the gift part. that's right, I'll rinse that. Make sure your gloves are always snug.

THE URANIUM
For what reason do you have a piece of uranium mineral in the studio? -All things considered, in light of the fact that it's cool. It's likewise somewhat freaky. what's more, since it was left off of a vital rundown that made the news. - Today. I'm declaring we're forbidding all imports of Russian oil and gas and energy. - It turns out the Russian Ukraine war is uncovering a issue that doesn't get that much inclusion, the atomic fuel production network, what's more, that could have significant effects on the eventual fate of atomic power in the US.
