Nano diamond embedded contact lens

According to an overseas version of the People’s Daily, researchers at the University of California recently invented a new drug delivery system that embeds nanodiamonds into contact lenses to deliver drugs to treat glaucoma. The researchers combined the drug with nanodiamond, and when the drug comes into contact with lysozyme in the tears, it is released and acts on the eye. Researchers say the treatment is good for drug delivery, and diamonds make contact lenses more durable in delivering drugs.

Steel Structures can be used in many industries such as foundation reinforce, electric power transmission structures and tubular scaffolding, etc.

A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.

Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':

There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
