Pesquisadores criam máscara térmica que inativa o coronavírus

Máscara criada pelo MIT aquece para matar o vírus causador da covid-19 MIT

Pesquisadores do Instituto de Tecnologia de Massachussets (MIT, na sigla em inglês) desenvolveram uma máscara facial que inativa o novo coronavírus, causador da covid-19, ao invés de apenas filtrar durante o uso. O estudo foi descrito no ArXiv, plataforma voltada para artigos acadêicos.

Segundo os cientistas, trata-se de um conceito totalmente inovador. Isso porque uma bateria de 9 volts é responsável por fornecer energia para uma malha de cobre que é aquecida a 90º C, temperatura capaz de tornar o vírus inativo, ou seja, incapaz de causar a doença, segundo modelos matematicos criados pelos pequisadores.

Neste caso, a máscara não filtra as partículas no ar como os modelos convencionais. “Na verdade, permite que o vírus atravesse a máscara, mas o desacelera e desativa”, afirma o autor sênior do estudo engenheiro químico Michael Strano em artigo publicado no MIT News, jornal.

Segundo Strano, uma vantagem da máscara aquecida é que não precisa ser descontaminadas ou jogadas fora depois de usar pois o vírus já está desativado.

“A perspectiva de ser capaz de respirar ar clinicamente estéril e expirar ar medicamente estéril, protegendo as pessoas ao seu redor e protegendo a si mesmo, é apenas o próximo passo. É uma tecnologia melhor”, afirmou.

Para evitar que a parte externa da máscara ficasse quente demais para ser utilizada, eles revestiram a malha de cobre de neoprone, material isolante térmico muito utilizado para confeccionar roupas de surf, por exemplo.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
