This month for WATWB, I am sharing two articles from ThomasNet, the digital outgrowth of the Thomas Register that describes itself as “a data, platform and technology company that has become the leading resource for the industrial marketplace.” I don’t know about all that, but I find some of the articles they publish to be fascinating. On November 14th, the two articles included here were part of the newsletter. They both seemed perfect for WATWB, so you get two for the price of one.
The first article is about technology that will help the world clean up after technology. One of the biggest problems technology brings with it is rapid obsolescence that leads to the need to recycle electronic components.
“According to New Atlas, one of the biggest problems in disassembling and recycling electronic components relates to the most basic ingredient in the product – the glue. And because the use of harsh solvents is often used to get them apart, the overall environmental friendliness is… not great.”
Researchers have worked to develop a new adhesive, one that makes it easier to disassemble the components. According to the article:
“The solution they’ve landed on is a polyurethane adhesive that’s packed with tiny iron oxide particles…
But the cool part is what happens when you want the pieces to come apart. When it’s sent off for recycling, the researchers say, the component utilizing the adhesive can be placed in a machine that generates a weak magnetic field that oscillates in such a way that the iron oxide particles heat up and the adhesive melts. The heat reportedly doesn’t extend to the bare hands of the people involved in the process, making it safe for recyclers as well.”
The second article is about how six scientists teamed up to save a turtle.
“Freddy was badly burned in a Brazilian brush fire. Because turtles depend on their shells for safety from predators, Freddy was in serious danger. After suffering two bouts of pneumonia because of the fire and surviving 45 days without food, he desperately needed a new shell.”
A group consisting of four veterinarians, a dental surgeon, and a 3D designer came to the rescue. They printed a shell that fit Freddy and they painted it to match his natural shell so he would still blend in with his surroundings.
“Freddy had lost a staggering 85% of his shell, so this was not just a simple print job. The work included taking 40 photos of a healthy turtle, then reconstructing it in 3D and inputting it into the computer. The shell was then printed in four pieces that fit together like a puzzle.
Made of corn-based plastic, each piece took 50 hours to print to make sure the new shell would be solid.”
The “We are the World” Blogfest is now in its third year. This blogfest’s goal is to spread the message of light, hope and love in today’s world. We are challenging all participants to share the positive side of humanity. This month’s co-hosts: Damyanti Biswas, Lizbeth Hartz, Shilpa Garg, Peter Nena and Simon Falk, welcome participants and encourage all to join in during future months. #WATWB is a blog hop on the last Friday of every month.
