CitarNew Aluminum-Sulfur Battery Tech Offers Full Charging In Under a MinutePosted by BeauHD on Wednesday August 24, 2022 @10:02PM from the promising-it-all dept.According to a new paper published in the journal Nature, researchers at MIT describe new aluminum-sulfur batteries that are made entirely from abundant and inexpensive materials and can be charged in less than a minute. "The new battery architecture, which uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between, is described today in the journal Nature, in a paper by MIT Professor Donald Sadoway, along with 15 others at MIT and in China, Canada, Kentucky, and Tennessee," reports MIT News. The caveat with this new kind of battery is that it requires a variety of molten salts that need to be "close to the boiling point of water." From the report:CitarIn their experiments, the team showed that the battery cells could endure hundreds of cycles at exceptionally high charging rates, with a projected cost per cell of about one-sixth that of comparable lithium-ion cells. They showed that the charging rate was highly dependent on the working temperature, with 110 degrees Celsius (230 degrees Fahrenheit) showing 25 times faster rates than 25 C (77 F). Surprisingly, the molten salt the team chose as an electrolyte simply because of its low melting point turned out to have a fortuitous advantage. One of the biggest problems in battery reliability is the formation of dendrites, which are narrow spikes of metal that build up on one electrode and eventually grow across to contact the other electrode, causing a short-circuit and hampering efficiency. But this particular salt, it happens, is very good at preventing that malfunction. The chloro-aluminate salt they chose "essentially retired these runaway dendrites, while also allowing for very rapid charging," Sadoway says. "We did experiments at very high charging rates, charging in less than a minute, and we never lost cells due to dendrite shorting."What's more, the battery requires no external heat source to maintain its operating temperature. The heat is naturally produced electrochemically by the charging and discharging of the battery. "As you charge, you generate heat, and that keeps the salt from freezing. And then, when you discharge, it also generates heat," Sadoway says. In a typical installation used for load-leveling at a solar generation facility, for example, "you'd store electricity when the sun is shining, and then you'd draw electricity after dark, and you'd do this every day. And that charge-idle-discharge-idle is enough to generate enough heat to keep the thing at temperature." This new battery formulation, he says, would be ideal for installations of about the size needed to power a single home or small to medium business, producing on the order of a few tens of kilowatt-hours of storage capacity.For larger installations, up to utility scale of tens to hundreds of megawatt hours, other technologies might be more effective, including the liquid metal batteries Sadoway and his students developed several years ago and which formed the basis for a spinoff company called Ambri, which hopes to deliver its first products within the next year. For that invention, Sadoway was recently awarded this year's European Inventor Award. The smaller scale of the aluminum-sulfur batteries would also make them practical for uses such as electric vehicle charging stations, Sadoway says. He points out that when electric vehicles become common enough on the roads that several cars want to charge up at once, as happens today with gasoline fuel pumps, "if you try to do that with batteries and you want rapid charging, the amperages are just so high that we don't have that amount of amperage in the line that feeds the facility." So having a battery system such as this to store power and then release it quickly when needed could eliminate the need for installing expensive new power lines to serve these chargers."The first order of business for the company is to demonstrate that it works at scale," Sadoway says, and then subject it to a series of stress tests, including running through hundreds of charging cycles.If you're looking for a detailed breakdown of how this new battery works, we recommend you check out Ars Technica's article here.Saludos.

El Madrid y el Barcelona nunca han jugado el mismo día y a la misma hora si no les tocaba jugar directamente entre ellos.De todos modos sigue siendo un buen ejemplo de por qué las matemáticas son tan importantes para administrar sistemas con una cierta complejidad.

Korean Nuclear Fusion Reactor Achieves 100 Million Degrees Celsius For 30 SecondsPosted by BeauHD on Wednesday September 07, 2022 @11:30PM from the moving-from-a-physics-problem-to-an-engineering-one dept.An anonymous reader quotes a report from New Scientist:CitarA nuclear fusion reaction has lasted for 30 seconds at temperatures in excess of 100 million degrees celsius. While the duration and temperature alone aren't records, the simultaneous achievement of heat and stability brings us a step closer to a viable fusion reactor -- as long as the technique used can be scaled up. [...] Now Yong-Su Na at Seoul National University in South Korea and his colleagues have succeeded in running a reaction at the extremely high temperatures that will be required for a viable reactor, and keeping the hot, ionized state of matter that is created within the device stable for 30 seconds.Controlling this so-called plasma is vital. If it touches the walls of the reactor, it rapidly cools, stifling the reaction and causing significant damage to the chamber that holds it. Researchers normally use various shapes of magnetic fields to contain the plasma -- some use an edge transport barrier (ETB), which sculpts plasma with a sharp cut-off in pressure near to the reactor wall, a state that stops heat and plasma escaping. Others use an internal transport barrier (ITB) that creates higher pressure nearer the center of the plasma. But both can create instability. Na's team used a modified ITB technique at the Korea Superconducting Tokamak Advanced Research (KSTAR) device, achieving a much lower plasma density. Their approach seems to boost temperatures at the core of the plasma and lower them at the edge, which will probably extend the lifespan of reactor components.Dominic Power at Imperial College London says that to increase the energy produced by a reactor, you can make plasma really hot, make it really dense or increase confinement time. "This team is finding that the density confinement is actually a bit lower than traditional operating modes, which is not necessarily a bad thing, because it's compensated for by higher temperatures in the core," he says. "It's definitely exciting, but there's a big uncertainty about how well our understanding of the physics scales to larger devices. So something like ITER is going to be much bigger than KSTAR". Na says that low density was key, and that "fast" or more energetic ions at the core of the plasma -- so-called fast-ion-regulated enhancement (FIRE) -- are integral to stability. But the team doesn't yet fully understand the mechanisms involved. The reaction was stopped after 30 seconds only because of limitations with hardware, and longer periods should be possible in future. KSTAR has now shut down for upgrades, with carbon components on the wall of the reactor being replaced with tungsten, which Na says will improve the reproducibility of experiments.The research has been published in the journal Nature.

Breakthrough: Air Pollution/Cancer Research Challenges the Science on TumorsPosted by EditorDavid on Sunday September 11, 2022 @06:57PM from the dream-of-gene-y dept."Scientists have uncovered how air pollution causes lung cancer," reports the Guardian, "in groundbreaking research that promises to rewrite our understanding of the disease."The BBC is calling it "a discovery that completely transforms our understanding of how tumours arise."CitarThe team at the Francis Crick Institute in London showed that rather than causing damage, air pollution was waking up old damaged cells. One of the world's leading experts, Prof Charles Swanton, said the breakthrough marked a "new era". And it may now be possible to develop drugs that stop cancers forming.The findings could explain how hundreds of cancer-causing substances act on the body. The classical view of cancer starts with a healthy cell. It acquires more and more mutations in its genetic code, or DNA, until it reaches a tipping point. Then it becomes a cancer and grows uncontrollably.... The researchers have produced evidence of a different idea. The damage is already there in our cell's DNA, picked up as we grow and age, but something needs to pull the trigger that actually makes it cancerous....Around one in every 600,000 cells in the lungs of a 50-year-old already contains potentially cancerous mutations. These are acquired as we age but appear completely healthy until they are activated by the chemical alarm and become cancerous. Crucially, the researchers were able to stop cancers forming in mice exposed to air pollution by using a drug that blocks the alarm signal.The results are a double breakthrough, both for understanding the impact of air pollution and the fundamentals of how we get cancer.

También apareció un profesor diciendo que cuando tiene que evaluar un texto y se da cuenta de que lo ha escrito una IA es una sensación increíblemente deprimente y de «vida desperdiciada» para él.Bonus: la traducción de la explicación completa sobre «Los problemas morales y sociales de utilizar la IA» está traducida con otra inteligencia artificial (en este caso, DeepL), al igual que el título de la anotación. Para ponerle la guinda, también la imagen está creada con una IA (Stable Difussion).Saludos.
