New molecular device could revolutionise medical and material engineering

New molecular device could revolutionise medical and material engineering

[ad_1] Scientists from The University of Manchester have developed a first-of-its-kind molecular device that uses force to control the release of multiple small molecules. The molecule device has a force-controlled release system that harnesses natural forces to trigger the targeted release of molecules. This could significantly advance the health sector and smart materials. The device uses a new technique that relies on an interlocked molecule known as rotaxane. Under the influence of mechanical force, this component triggers the release of functional molecules to target the area in need. For example, medicines or healing agents can be released to target the site of a tumour. The new device also holds promise for self-healing materials that can repair themselves in situ when damaged, such as a scratch on a phone screen. The discovery is published in the journal Nature. The new device overcomes previous challenges Traditionally, the controlled release of molecules with force has presented challenges in releasing more than one molecule at once. Usually, the system operates through a molecular ‘tug of war’ game where two …

Scientists Splice Material From Creature That Can Survive Outer Space Into Human Cells

Scientists Splice Material From Creature That Can Survive Outer Space Into Human Cells

[ad_1] Image by Getty / Futurism An almost-microscopic creature that’s sturdy enough to survive the ravages of space may hold the key to human longevity, scientists have found in new research. In a new study led by the University of Wyoming, an international team of researchers found that when looking into the incredible durability of the itty bitty tardigrade — known affectionately as the “water bear” or “moss piglet” — proteins from the creature might help slow aging in humans, too. Part of what’s made tardigrades so famous is that they can survive both boiling and freezing temperatures, which was why in 2007 a team of European scientists sent 3,000 of these half-millimeter-long little guys into space, and weren’t so shocked when the majority of them survived. When they’re threatened by temperatures, radiation, or other dangerous conditions, water bears go into a self-protective state of suspended animation known as biostasis — and it was that mechanism that interested molecular biologist and UW assistant professor Thomas Boothby, an expert in the field of tardigrades. In the …

Physicists have worked out how to melt any material

Physicists have worked out how to melt any material

[ad_1] Predicting when solids will melt is more difficult than you might think r.classen/Shutterstock Physicists may finally have an answer for a seemingly simple question that has remained unanswered for about a century: when does a substance melt? Kostya Trachenko at Queen Mary University of London found it mysterious that “in this age of scientific and technological development”, physicists do not always know how to predict at what temperature and pressure a material will melt. He has now derived an equation that can be used to make such predictions for a vast… [ad_2] Source link

New material neutralizes 96-percent of virus cells using nanospikes

New material neutralizes 96-percent of virus cells using nanospikes

[ad_1] Researchers at Australia’s Royal Melbourne Institute of Technology (RMIT) have combined brute force with high tech manufacturing to create a new silicon material for hospitals, laboratories and other potentially sensitive environments. And although it might look and feel like a flat, black mirror to humans, the thin layering actually functions as a thorny deathtrap for pathogens. As recently detailed in the journal ACS Nano, the interdisciplinary team spent over two years developing the novel material, which is smooth to the human touch. At a microscopic level, however, the silicon surface is covered in “nanospikes” so small and sharp that they can impale individual cells. In lab tests, 96-percent of all hPIV-3 virus cells that came into contact with the material’s miniscule needles either tore apart, or came away so badly damaged that they couldn’t replicate and create their usual infections like pneumonia, croup, and bronchitis. With no external assistance, these eradication levels could be accomplished within six hours. A virus cell on the nano spiked silicon surface, magnified 65,000 times. After 6 hours it …

Emissions Are Not A Material Risk To Investors Or Companies, SEC’s Climate Disclosure Rule Is

Emissions Are Not A Material Risk To Investors Or Companies, SEC’s Climate Disclosure Rule Is

[ad_1] Authored by Justin Bis via RealClear Wire, The Securities and Exchange Commission is at it again. Straying from its core mission of “protecting investors, maintaining fair, orderly, and efficient markets, and facilitating capital formation,” the SEC is now taking the mantle of climate activist. Chairman Gary Gensler’s signature policy, the Climate Disclosure Rule, was just approved in a partisan 3-2 vote. Companies will now have to disclose direct and indirect emissions that they produce to investors. This rule, in the guise of informing investors of material risks in companies, will overwhelm investors with information that is unrelated to actual risks to a company’s performance. For example, how do the emissions coming from a company’s truck make an investment in that company riskier to investors? In this example at least, the answer is it doesn’t. But even if you could find an example, the SEC already requires companies to disclose material risks, and insurers – whose entire business depends on analyzing and assigning material risk – do not factor in emissions.  So, what is the …

Instructions for a Teenage Armageddon: Bridgerton star Charithra Chandran makes the best of meagre material

Instructions for a Teenage Armageddon: Bridgerton star Charithra Chandran makes the best of meagre material

[ad_1] Chandran is a likeable presence onstage and makes the best of meagre material. At first, her character has a brittle carapace of cynicism, quipping that after four years of her sister starving herself “at least the coffin will be light” for those carrying it. She snipes at her parents (Shelley Conn and Philip Glenister, seen on video) as they drive to the funeral home and creates broad caricatures of other adults. The most effective moments come when she evokes the unease of schoolmates, unable to express sympathy and fearful of “catching” an eating disorder. Things go seriously awry when she meets Ella (Irene Pappas, also seen on video), a fag-chuffing American bitch in the Mean Girls mode, even though the story is apparently set in Acton. Through Ella, Day tries to weave together ideas about peer pressure, toxic online culture, grooming and consent. Chandran brings wet-eyed vulnerability to this section which is harrowing but incoherent. The ending is too pat and frankly awful. I don’t doubt the sincerity of anyone involved. Not Day, who’s …

NTU researcher pleads guilty to possessing child abuse material, asking to have sex with 12-year-old girls

NTU researcher pleads guilty to possessing child abuse material, asking to have sex with 12-year-old girls

[ad_1] About 90 photographs constituted child abuse material, with naked girls featured in compromising positions. Herrin had downloaded these photographs from a few websites and had been downloading such material since 2019, according to the prosecution. Apart from photographs, Herrin’s phone also contained 31 obscene films. This charge will be considered for sentencing.  Investigators also found WhatsApp messages between Herrin and an unknown person on Nov 14, 2019, where Herrin offered four million rupiah (S$340) for sex with 12-year-old girls.  Herrin is due to return to court on May 17.  For communicating with another person to obtain sexual services of a minor, Herrin can be jailed up to two years, fined, or both per charge. For possessing child abuse material, he can be jailed up to five years, and fined or caned.  [ad_2] Source link

Pursuing cathode active material purity in EV battery manufacturing

Pursuing cathode active material purity in EV battery manufacturing

[ad_1] Anoop Suvarna, Global Battery Materials Manager for Energy Storage at Pall Corporation, discusses how cathode active material filtration technology optimises the efficiency of lithium batteries for use in EV manufacturing. A global drive to reduce emissions and encourage more sustainable transportation is prompting advancements in EV manufacturing. Mandates in some territories for manufacturers to produce higher percentages of EVs and state-backed exports from other countries are fuelling competition. Meanwhile, research on variable battery materials and debates on vehicle size and charging infrastructure are leading to new avenues being explored. For most auto manufacturers, lithium-ion batteries remain the best option to power their vehicles due to their energy capacity, fast charging, low discharge rate and lifespan. Yet astute battery producers know they must develop units that operate more efficiently than their rivals to be preferred suppliers. Each battery’s four functional components – the cathode, anode, separator, and electrolyte – contribute to its efficiency. The formation of the cathode – or positive electrode – is the most complex process in manufacturing EV batteries, and its composition …
