Why graphene hasn’t taken over the world...yet

Описание

Graphene is a form of carbon that could bring us bulletproof armor and space elevators, improve medicine, and make the internet run faster — some day. For the past 15 years, consumers have been hearing about this wonder material and all the ways it could change everything. Is it really almost here, or is it another promise that is perpetually just one more breakthrough away?

Nuclear Fusion Energy: The Race to Create a Star on Earth

Nuclear Fusion Energy: The Race to Create a Star on Earth

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy. We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

This monster plant is trying to take over. What if we let it?

This monster plant is trying to take over. What if we let it?

Silicon Valley is home to tech giants, venture capital…and a years-long battle between an invasive species, a tiny bird, and a bunch of scientists trying to decide what counts as “nature.” We put on the biggest boots we could find and headed out to the strange salt flats of the San Francisco bay to check it out. NOTE: All footage of U.S. and California Fish and Wildlife Service land was obtained via special agreement with those agencies. Filming on said land requires a Special Use Permit. Additionally, launching, landing, or operating an unmanned aircraft (drone) from or on lands and waters administered by the California and U.S. Fish and Wildlife Services is prohibited unless special permits are obtained.

Why America still uses Fahrenheit

Why America still uses Fahrenheit

Fahrenheit, explained to the rest of the world Since I've moved to the US in 2010, there's one thing that I still don't fully understand: the imperial system. Virtually every country on earth uses Celsius but America has yet to follow. Although it might not seem like a big deal, not using the metric system puts America at a great disadvantage. For example, American kids have to learn 2 sets of measurements making science education even more difficult. On top of that, American companies have to produce extra products to export to metric countries. So why does the United States still have such an antiquated system of measurement? Read more about Fahrenheit here: https://www.vox.com/2015/2/16/8031177/america-fahrenheit Read more about the metric system here: https://www.vox.com/2014/5/29/5758542/time-for-the-US-to-use-the-metric-system Subscribe to our channel! http://goo.gl/0bsAjO Vox.com is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.

Most AMAZING Materials Of The Future!

Most AMAZING Materials Of The Future!

Check out the most amazing materials of the future! This top 10 list of the strangest and coolest materials shows that science is getting very futuristic nowadays! Subscribe For New Videos! http://goo.gl/UIzLeB Watch our "UNSOLVED Mysteries That Cannot Be Explained!" video here: https://youtu.be/-4affLOd_7Q Watch our "Most Amazing Cities Found UNDERWATER!" video here: https://youtu.be/rUqxhYJqGhU Watch our "MYSTERIOUS Things Discovered In WEIRD Places!" video here: https://youtu.be/VtiF8vhBLHY 13. Aerogel Aerogel holds 15 entries in the Guinness Book of Records for material properties, more than any other material. It is the world’s least dense solid. Sometimes called “frozen smoke”, aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon. It’s 99.8% empty space, which makes it look semi-transparent. Aerogel is also a fantastic insulator. If you had a shield of aerogel, you could easily defend yourself from a flamethrower. It stops cold and it stops heat. You could even build a warm dome on the Moon. Aerogels have unbelievable surface area in their internal fractal structures. Cubes of aerogel with just an inch on one side may have an internal surface area equivalent to a football field. Aerogel is currently being used as an insulation product, thickening product in cosmetics, laser targets, blankets, in space suits, military armor, and in particle physics, just to name a few. Fun fact: NASA used an aerogel to trap space dust particles aboard the Stardust spacecraft. The particles vaporize on impact with solids and pass through gases, but can be trapped in aerogels. And to think that Aerogel was created from a bet! 12. Carbon nanotubes Carbon nanotubes are long chains of carbon held together by the strongest bond in all chemistry, the sacred sp2 bond, even stronger than the sp3 bonds that hold diamonds together! Carbon nanotubes have numerous remarkable physical properties, including ballistic electron transport, which makes them ideal for electronics, and so much tensile strength that they are the only substance that could be used to build a space elevator. Yup! Just like the one that Google is trying to build!! Nanotubes could be used to build a pipe that transports materials and maybe even humans to the International Space Station or the moon! The specific strength of carbon nanotubes is 48,000 kilonewtons per kg. The previous record holder for structural strength was high-carbon steel, with a measly 154 kilonewtons per kg. That’s 300 times stronger than steel. You could build towers hundreds of kilometers high with it. Or the world’s strongest, and tiniest straw. Your pick. 11. Metamaterials “Metamaterial” refers to any material that gains its properties from structure rather than composition. Metamaterials have been used to create microwave invisibility cloaks, 2D invisibility cloaks, and materials with other unusual optical properties. Mother-of-pearl gets its rainbow color from metamaterials of biological origin. Some metamaterials have a negative refractive index, an optical property that may be used to create “Superlenses” which resolve features smaller than the wavelength of light used to image them! This technology is called subwavelength imaging. Metamaterials would be used in phased array optics, a technology that could render perfect holograms on a 2D display. These holograms would be so perfect that you could be standing 6 inches from the screen and not even notice it’s a hologram. 10. Aluminum Bubble Wrap Imagine your favorite packing-based stress reliever, except made of metal. OK, metallic bubble wrap might not be quite as easy to pop, but it could be a heck of a lot more useful. A team of engineers from North Carolina State University have developed a new form of aluminum bubble wrap, which they claim could revolutionize packaging and protective equipment. The scientists take a thin sheet of aluminum, then use a studded roller to form small indents in the sheet. Unlike its polyethylene counterpart, these voids are then filled with a foamed material like calcium carbonate, before being sealed with another flat sheet of metal. The result is a series of bubbles that absorb masses of energy, weighs 30 percent less than regular sheet metal, and yet are nearly 50 times stronger. It's easy to make, not too expensive, and could soon be used in everything from shipping containers for fragile goods to bike helmets. Just don't be tempted to try and pop it. Origins Explained is the place to be to find all the answers to your questions, from mysterious events and unsolved mysteries to everything there is to know about the world and its amazing animals!

It costs 70 MILLION dollars per kg! But why?

It costs 70 MILLION dollars per kg! But why?

Sometimes science can be expensive!!! I frequent deal with stable isotopes which can happily reach tens of thousands of dollars per gram. In this case ~$70 000 per gram for 41K. In this case I only had about 1/3rd of a gram. Now it might seem like a lot, but bear in mind this is not really something you can sell. The market for 41K in the entire world is almost nothing. Indeed the only thing that gives it value is it costs so much to make it. Thankfully, this stuff did good work! We got some of the best measurements on the hydration of potassium in the world!! Indeed they were good enough to highlight some of the previous knowledge about 41K, to the point where I had to bring this sample out of retirement and send it back to the reactor to check the properties of the nucleus. I wont be adding this to the patreon feed, but many thanks to all those who support this channel! https://www.patreon.com/Thunderf00t

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether?

How Microwaving Grapes Makes Plasma

How Microwaving Grapes Makes Plasma

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they touch. This creates heating, sparks, and plasma, which is further fed with energy directly by the microwaves. Huge thanks to Hamza Khattak, Prof. Pablo Bianucci and Prof. Aaron Slepkov (unavailable for the call) for chatting to me and helping me understand the physics of this cool phenomenon.

A microscopic look at why the world is running out of sand

Humans are using more sand than the Earth is naturally producing, and that’s a problem for the global construction industry. But it turns out that the usefulness of sand depends on the science of each tiny little grain. We went on a sand scavenger hunt to collect some samples, look at them under a microscope, and try to figure out why sand scarcity is such a problem.

Even though Albert Einstein (together with collaborators in the EPR Paradox paper) wanted to show that quantum mechanics must be incomplete because it was nonlocal (he didn't like "spooky action at a distance"), John Bell managed to prove that any local real hidden variable theory would have to satisfy certain simple statistical properties that quantum mechanical experiments (and the theory that describes them) violate. Since then, GHZ and others have managed to extend the theoretical work, and Alain Aspect performed the first Bell test experiment in the late 1980s.

I changed a lot of my preconceptions, specifically I thought: 1. That the Earth's magnetic field was a passive thing - it shouldn't need a continuous input of energy to maintain itself (that seemed reasonable to me because the magnetic field has been around for a long time and it seems mostly stable). But as it turns out, the Earth is a giant electromagnet, and so of course those currents dissipate their energy as they encounter resistance in the liquid metal through which they flow. So the energy to continuously create these currents comes from the kinetic energy of the liquid metal flows in the Earth's outer core. 2. If it's convection, I'm thinking hot things rising, cooler things falling. But apparently the main effect driving convection is the compositional differences at the boundary with the Earth's inner core. This is because of the differential freezing at the boundary. Things like iron freeze into the inner core, while elements like sulfur do not. Hence the pockets of lighter material which then rise outwards. 3. I didn't get why the fluid motion was necessary for the generation of the magnetic field. I mean if it's a conducting liquid, it can conduct currents whether it moves or not. But the key is that the liquid metal can 'trap' magnetic fields. I imagine this like how iron channels magnetic fields. Then once these fields are channeled, they can be pulled and stretched, making more magnetic field. 4. Fluids operate very differently in rotating frames of reference. This is something I didn't intuitively grasp. But, as fluids move from the inner core outwards, those particles are moving much more slowly in the direction of rotation than the matter that has been there for a long time, which means the convection currents get deflected and form helices.

2 of the most exciting carbon based materials currently being investigated by researchers are carbon nanotubes, and graphene. Adding small amounts of these to other materials can radically change the materials properties. From making highly conductive inks, to super strong materials, and even to computers, it seems the whole scientific world is trying to use these materials in one way or another. But how can they be manufactured? Of the two graphene is far easier to make as it can be harvested from naturally occurring materials. In this video we explore the easier way to make it in bulk and use a simple electrochemical method to shear the microscope layers of natural graphite apart into individual graphene sheets.

What makes muscles grow? - Jeffrey Siegel

View full lesson: https://ed.ted.com/lessons/what-makes-muscles-grow-jeffrey-siegel We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible. Lesson by Jeffrey Siegel, animation by Brett Underhill.

25 STRONGEST Materials Known to Man

25 STRONGEST Materials Known to Man

Diamonds are the strongest materials known to man, right? You might be surprised to find out they are not. In fact, you may be surprised to discover some of the items considered as some of the toughest items man has ever known. Check out these 25 strongest materials known to man. We are always looking for the strongest materials. It allows us to create things that can withstand more abuse. Things like taller buildings, stronger cars, and protection for law enforcement. But contrary to what you might think, these stronger items are not bigger or heavier. Often, they are smaller and lighter. Care to find out which are the strongest materials known to man? Then check out our list (and our photo credits and sources) and let us know in the comments below how you think these materials could be used: http://list25.com/25-strongest-materials-known-to-man/ SUBSCRIBE - http://bit.ly/2uwq6BJ Follow us on: List25 Facebook - https://www.facebook.com/list25 List25 Instagram: https://instagram.com/list25/ List25 Twitter - https://twitter.com/list25 List25 Pinterest: https://www.pinterest.com/list25/ See more lists on our website: http://list25.com By now, we’re pretty sure that you’ve heard that diamonds are the strongest materials known to man. However, this isn’t necessarily true. There are materials that are tougher than diamonds such as Carbyne. But even if the material is not tougher than diamond, it impressive to see how durable some materials can be. Take Graphene for example. A one atom thick sheet is 200 times stronger than steel. You’re probably familiar with Kevlar. Used in bullet proof vests, Kevlar has a tensile strength that is 8 times that of steel and can with stand temperatures reaching 450℃.
