Reply to comment by iam666 in Scientists create carbon nanotubes out of plastic waste using an energy-efficient, low-cost, low-emissions process. Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide by Wagamaga

Yeah CNTs vary quite a bit by size, quality and strength, and they have found CNTs in unprocessed diesel exhaust, so finding them in super heated plastic wasn’t a big shock to me. They can turn plastic junk into plastic junk with some nanotubes, which is cool, but not a marketable application yet, as some on this thread hope.

Isn't the new Airbus made from CNTs instead of usual aluminum alloy? Which gave the plain a huuge edge. It def has potential in aviation.

The short strands are used for surface coatings, and showed a lot of novel electronic properties that just weren't useful because of material costs.

We'd all like an easy answer for a space elevator, but faster, cheaper, or more efficient, electronics is always a bonus.

Helped, High LDL reduced IL-10 which enabled more CD4+T cells to differentiate into central memory-like phenotype - which is essential for prolonged anti-tumor immunity and durable response to checkpoint blockade.

There is a positive correlation between obesity and response to checkpoint blockade, this may be fishing out the reason why.

The tech is being used by a company called Universal Matter - they just reached a milestone of being able to produce 1 ton of graphene a day at 35$ a ton from mixed plastic waste. Their commercial scale plant is being built now.

It does use a lot of energy, however, it takes only a few microseconds to reach the temperature needed to convert the mixed waste to graphene. Tbh, it’s pretty revolutionary technology. It extends way further than just making strong materials. It can be used for soil enrichment, isolation of rare minerals, and almost (most importantly) converting coal ash (highly toxic) to inert materials. All at a profit. It’s sad that everything has to operate on a scale of “profitability”, but the Tour group has cracked the code!

This can't be true, can it? Oncologists everywhere are so beholden to pharmaceutical companies that they won't prescribe vitamin C intravenously? This sounds like a thing I would've heard of by now, a vast global conspiracy to deny cancer patients across the globe a simple and cheap cure.

Reply to comment by [deleted] in Climate change and the projected savannization of the Brazilian Amazon threaten most land-based mammals that live there, new research shows. The “savannization” here refers to when lush rainforest gives way to a drier, open landscape that resembles savanna but is actually degraded forest. by MistWeaver80

It's insanity. I don't even click on stories like this because I only feel helpless and depressed.
