According to the researchers, the new invention acts as a reverse filter, capable of blocking small particles while simultaneously allowing large ones to pass through. The researchers envision a variety of uses, including enabling military doctors to perform open surgery on the battlefield.
According to the scientists, the membrane will enable surgical tools to pass through the membrane to access the wound, while keeping out dust particles and other debris – ensuring a clean environment to safely operate.
'The membrane filter could potentially prevent germs, dust or allergens from reaching an open wound, while still allowing a doctor to perform surgery safely,' said Tak-Sing Wong from Penn State University, who was involved with the research.
Conventional filters, like those used in coffee machines or sieves, work on particle size and let through small objects while capturing larger ones. This innovative new membrane works in a different way and responds to an object's kinetic energy – not its size.
The team experimented with liquids and manipulated their properties when developing the space-age material.
'Typically, a smaller object is associated with lower kinetic energy due to its smaller mass. So, the larger object with a higher kinetic energy will pass through the membrane, while the smaller object with lower kinetic energy will be retained.'
In addition, the membrane wraps around the object as it passes through, allowing the membrane to completely self-heal over the top.
In its simplest form, the membrane can be created with water and has a structure similar to that of a biological cell membrane.

Interesting technology with many potential uses. Thanks for posting.
One application is surgery. But they don't tell us what this 'space-age material' is made of.
Were liquid properties manipulated with chemicals? Are these chemicals toxic? Is it safe to cover open wounds? Can you survive the surgery only to die of cancer later? What happens if this space-age liquid enters the bloodstream? How will it affect cell function if absorbed by the body?
An interesting material looking for a real-world use.
That’s amazing. Thanks for posting.

so i can drive my car through it but my chihuahua won’t be able to pass through? What if the chihuahua is in hte car? Questions, Questions!
“One application is surgery. But they don’t tell us what this ‘space-age material’ is made of.”
Whenever anyone gives a military case study, that means it’s really, really bad for you.
Separating egg yolks seems like a good use of this...
Amazing...
If it ever goes retail, I’m putting a couple in my G.O.O.D. bag...
Guessing it has something to do with the ratio of surface tension and the amount of charge on the liquid particles in the filter.
Cool stuff. Wonder how it does with liquids - I could see a pipe lined with this stuff over a catch tray. As the liquid passes any debris falls through the bottom while the liquid passes right along.

Sounds remarkable, but can we really trust a guy to fly an airplane who can’t follow directions when taxiing?
Cool Tech PING
Thank You for Posting this.
This is very odd, and very clever, technology. It will be interesting to see how far it can be taken.
......new approach to a sucking chest wound ??
Sounds like it. They mentioned Battlefield Surgery with Surgical Tools in/out and dirt/rocks stay out. Very nice if true.
Saw a commercial for incontininace underwear that sounded a lot like Civilian Quick Clot in an Emergency. Probably cost less than QC and if it stems a bleed out then it’s done the job. Sterility is not a huge concern if it stops the blood flow.
If given the choice as they rolled you into the ER what would you decide?
