Crazy: Die Bundeswehr will das #MFG5 Gelände, Holtenau-Ost zurückkaufen.
Dann geht es mit dem Fahrrad wieder nur an der B503 nach Friedrichsort aber die Stadtkasse dürfte saniert sein…

🧑🔬Engineers develop ECO-friendly Plastic from Mineral found in Seashells.
According to UNESCO, plastic waste makes up 80% of all #marine #pollution, with 8–10 million metric tons of plastic making its way into our oceans each year. USC Viterbi School of Engineering researchers have discovered a mineral commonly found in seashells could be the key to a safer #plastic #alternative.

![The research is led by Eun Ji Chung, the Dr. Karl Jacob Jr. and Karl Jacob III Early-Career Chair at USC Viterbi School of Engineering and a leading expert in engineered nanoparticles for clinical applications. Chung has a background in biomaterials, and her lab recently developed a new biocompatible plastic alternative by adding calcium carbonate from seashells into poly [1,8-octanediol-co-citrate] [POC], an FDA-approved biodegradable material used in orthopedic fixation devices.
Chung began to revisit work she had done as a graduate research student, where she worked on a biodegradable polymer made of citric acid, which is found in oranges. The research from this work was geared towards creating polymers for biomedical applications for sutures and tendon fixation devices.
"In graduate school, we added hydroxyapatite, which are these calcium particles that are in your bone, and I fabricated them together, and they are now biodegradable materials that are already FDA-approved," said Chung. "I started thinking that seashells have calcium, too. That's why they're stiff like bone. But they have a different kind of calcium particle. So, I basically adapted what I did and replicated it to be more suitable for an alternative plastic material."](https://inne.city/photo/preview/640/827503 "The research is led by Eun Ji Chung, the Dr. Karl Jacob Jr. and Karl Jacob III Early-Career Chair at USC Viterbi School of Engineering and a leading expert in engineered nanoparticles for clinical applications.

The Chung Lab's biocompatible plastic substitute can be used as a replacement for beverage holder rings.
The researcher said the citric acid polymer's texture is sticky, like a gum. When the calcium particles are added and it is heated and cured in an oven, it forms a plastic-like material. The resulting material [POC-CC], was developed into a prototype and cut into the formation of soda can beverage holder rings that were robust enough to hold cans.
The team hypothesized that the POC-CC material would be a biocompatible plastic substitute that could degrade in marine environments while maintaining sufficient strength for industrial applications. Chung added that the material had many potential applications, such as in the production of biodegradable straws that were stronger than bamboo or paper straws and safer than reusable metal ones.](https://inne.city/photo/preview/640/827505 "[ImageSource: The Chung Lab at USC Viterbi School of Engineering]

“POC and POC-CC synthesis process. (a) POC-CC synthesis scheme: POC pre-polymer is formed followed by CC incorporation and further polymerization. (b) POC pre-polymer. (c) POC pre-polymer solution incorporating CC in 5 in. diameter Teflon dish. (d) POC-CC after casting onto 6 × 12 in. Teflon sheet.”
To test this, POC-CC was synthesized with varying concentrations of calcium carbonate. Over six months, they observed various factors including the weight degradation rate in ocean water and the effect the material had on the pH of the water after long-term incubation.
"Our results show the degradation rate increases with increased POC content, and the addition of CC maintains the pH of ocean water," Chung said.
👾Another benefit of the material is its biocompatibility — it doesn't cause harm to marine life in the way that introduced microplastics do. The research team incubated a type of green algae [Scenedesmus sp.] alongside the POC-CC material, housing them in simulated ocean water for six months. The team noted high cell viability, confirming the fact that the POC-CC plastic substitute was biocompatible with marine microorganisms.👾

Record-breaking sea temperatures in the Mediterranean spark fresh warnings from scientists

The #Mediterranean is considered one of the #world’s most vulnerable ‘climate change hotspots’, warming much faster than the global average. Without action to curb climate change, experts warn that persistent #marine #heatwaves - prolonged periods of abnormally high ocean #temperatures - could change the region beyond recognition.

Zum #Schiffssamstag ein Foto der alten Galeone "Vasa" (Wasa), die in einem eigenen Museum in Stockholm ausgestellt ist.
Das falsch konstruierte Schiff sank nach nur 20 Minuten Jungfernfahrt am 10. August 1628 in den Schären Stockholms.
1961 wurde die Vasa geborgen, restauriert und konserviert; seither befindet sie sich in ihrem Museum.

Sperm whale spotted in Monterey bay today (not very common)!
I like that I read this post and saw ‘tail database’ and I knew exactly which one (happy whale)
Can’t wait to get back in the water and see some whales (I get to go any time I want for free hehe)
After 8 months at this job I have become the sort of person who says random marine facts (‘did you know some southern sea otters eat so much purple sea urchin that their skulls turn purple’) at parties
