Bright and tough: A material that heals itself and glows
A research team at the RIKEN Center for Sustainable Resource Science (CSRS) has succeeded in developing a self-healing material that is also capable of emitting a high amount of fluorescence when absorbing light. The research, published in the Journal of the American Chemical Society, could lead the way to the creation of new materials such as organic solar cells that are more durable than current types.
In 2019, Zhaomin Hou and his team at RIKEN CSRS successfully copolymerized ethylene and anisylpropylene using a rare-earth metal catalyst. The resulting binary copolymer displayed remarkable self-healing properties against damage. The copolymer's soft components, alternating units of ethylene and anisylpropylene, coupled with hard crystalline units of ethylene-ethylene chains, acted as physical cross-linking points, forming a nano-phase-separated structure that proved crucial for self-healing.
Building upon this success, they incorporated a luminescent unit, styrylpyrene, into a monomer and then formed polymers that also included anisylpropylene and ethylene. This process led to the synthesis, in a single step, of a self-healing material with fluorescence characteristics.
New oc time!!!
This one was made specifically to fit into a roleplay I’ve got going on with a friend.
Her name is Lumi (Short for Luminescence, a nickname given to her by Starlight so they could differentiate between the two of them since her manufactured name is Starbright.) She and Starlight are supposed to be twin animatronics of sorts, though Lumi is moreso a security bot than a child care attendant.
They do aerial shows and keep other bots out of trouble.
i like drawing glowy things, so i had to do this one :)
not sure why, but medibang decided to eat my quality here, not much i can do about it, but its not too noticeable if you're not looking for it! wait, no - stop looking for it!
I have a personal head cannon, that, as nature spirits, nm and dream can both use elemental magic, but not use bones or blasters like sanses can, so heres my interpretation of that!
Researchers hijack solar cell technology to develop a simple spray test for lead
AMOLF researchers have used the special properties of perovskite semiconductors to develop a simple spray test to demonstrate the presence of lead. Perovskite is a material suitable for use in LEDs and solar cells, for example. A lead-containing surface shines bright green when it is sprayed with the test. This test is 1,000 times more sensitive than existing tests and the researchers found no false positive or false negative results. The study was published on November 27 in the journal Environmental Science & Technology.
"We have hijacked the technology of perovskite semiconductors and used it in a widely deployable lead test. Nobody in this discipline had ever thought of that," says Lukas Helmbrecht, researcher at the group Self-Organizing Matter led by Wim Noorduin at AMOLF. "We are very pleased with these results," says Noorduin. "It is a really cool project and it is quite rare for fundamental research to literally impact the entire world with an application."
