Highly Effective New Way Developed to Paint Complex 3D-Printed Objects

Posted by in categories: biotech/medical, materials

Rutgers engineers have created a highly effective way to paint complex 3D-printed objects, such as lightweight frames for aircraft and biomedical stents, that could save manufacturers time and money and provide new opportunities to create “smart skins” for printed parts.

The findings are published in the journal ACS Applied Materials & Interfaces.

Conventional sprays and brushes can’t reach all nooks and crannies in complex 3D-printed objects, but the new technique coats any exposed surface and fosters rapid prototyping.

A new material made from carbon nanotubes can generate electricity

Posted by in categories: chemistry, nanotechnology, particle physics, robotics/AI

MIT engineers have discovered a new way of generating electricity using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an , draws electrons out of the particles, generating a current that could be used to drive or to power micro-or nanoscale robots, the researchers say.

“This mechanism is new, and this way of generating is completely new,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. “This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires.”

High-density hard drive packed with graphene stores 10 times the data

Posted by in categories: computing, particle physics, space

Researchers have found that graphene-enhanced hard drives can store data at ten times the density of existing HDDs.


By leveraging the wonder material graphene, a group at the University of Cambridge is claiming an advance in data storage that resembles more of a leap than a step forward. The new design unlocks higher operating temperatures for hard disk drives (HDDs) and with it, unprecedented data density, which the team says represents a ten-fold increase on current technologies.

In a HDD, data is written onto fast-spinning platters by a moving magnetic head. Special layers called carbon-based overcoats (COCs) protect these platters from mechanical damage and corrosion during operation, though these can only perform within a certain temperature range and also take up a lot of space.

11 Top Life Extension Blogs For Longevity Enthusiasts

Time To Rethink Theories: Physicists Predict Neutron Stars May Be Bigger Than Previously Imagined

Posted by in categories: cosmology, physics

When a massive star dies, first there is a supernova explosion. Then, what’s left over becomes either a black hole or a neutron star.

That neutron star is the densest celestial body that astronomers can observe, with a mass about 1.4 times the size of the sun. However, there is still little known about these impressive objects. Now, a Florida State University researcher has published a piece[1] in Physical Review Letters arguing that new measurements related to the neutron skin of a lead nucleus may require scientists to rethink theories regarding the overall size of neutron stars.

Amazon Founder Jeff Bezos to Be on Blue Origin’s First Human Space Flight

Posted by in category: space travel

Jeff Bezos plans to travel to space next month as one of the first passengers carried by Blue Origin, the Amazon.com Inc. founder’s space company.

Mr. Bezos said in an Instagram post Monday that he will be one of the inaugural passengers on Blue Origin’s New Shepard spacecraft, during its first crewed flight scheduled for launch from West Texas on July 20. Mr. Bezos said that his brother, Mark Bezos, will also be on board.

“I want to go on this flight because it’s a thing I’ve wanted to do all my life,” Mr. Bezos said in a video posted to Instagram. “It’s an adventure. It’s a big deal for me.”

New tech cheaply produces lithium and H2, while desalinating seawater

Posted by in categories: chemistry, security, sustainability

With the rise of the lithium-based battery, demand for this soft, silvery-white metal – the lightest solid element in the periodic table – has exploded. With the race to zero carbon by 2050 gathering steam, forcing the electrification of transport, lithium will be an even more valuable asset in the next 30 years.

The supply of raw materials for batteries could even end up being a national security issue, too; China’s global leadership on high-volume EV production has put it ahead of the game, and while the majority of ground-based lithium reserves are in the “lithium triangle” of Chile, Bolivia and Argentina, China controls more than half’s the world’s supply simply through investments and ownership. It has shown in the past that it’s not afraid to wield commodity supplies as a weapon.

But as with other metals like uranium, land-based lithium reserves pale in comparison to what’s out there in the sea. According to researchers at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), there’s about 5000 times as much lithium in the oceans as there is in land deposits, and a newly developed technology could start extracting it cheaply enough to make the big time – while producing hydrogen gas, chorine gas and desalinated water as a bonus.
