A group of investigators led simply by Steve Armes.

Then they added this polymer to the typical chemical reaction blend used to create iron oxide nanoparticles. The resulting particles have the average diameter of 34 nanometers approximately, with the iron oxide primary having an average size of 9 nanometers and a variety of 6 to 14 nanometers. Compared, iron oxide nanoparticles ready without the covering had an average size of 13 nanometers and a variety of 9 to 21 nanometers. The magnetic properties of the stabilized nanoparticles had been comparable to those of regular iron oxide nanoparticles.

They have to use more and more cocaine to get the same highs. Doing this after that puts users at an increased risk for stroke and heart attack. People who snort cocaine a whole lot over a long time period can lose their sense of smell or damage their nostrils. They could have plenty of nosebleeds, hoarseness, or difficulty swallowing. Injecting cocaine and sharing needles increases the threat of getting diseases like hepatitis or HIV/AIDS greatly. Taking a huge dose of cocaine or using it in binges can lead people to become edgy and irritable.
