Properties and Synthesis of Detonation Nanodiamonds
- Diamond yield after detonation depends on synthesis condition and cooling capacity
- Cooling capacity affects diamond yield, which can reach 90%
- Diamond is extracted from soot using high-temperature high-pressure boiling in acid
- Diamond grains in soot are around 5nm in size and form micrometer-sized clusters
- Nanosized diamond has a large relative surface area and can attach molecules from the atmosphere
- Nanodiamonds can be synthesized from graphite in organic liquid using ultrasonic cavitation
- High-energy laser pulses can be used to irradiate graphite and produce diamond
- Nanodiamonds can be produced at near-ambient conditions by a microplasma process
- Nanodiamonds formed from gas require no surface to grow on
- Alternative methods offer competitive cost compared to the HPHT process
Applications of Nanodiamonds
- Nanodiamonds are used in lapping and polishing
- They are added to engine oils as additives
- Nanodiamonds serve as dry lubricants for the metal industry
- They are used as reinforcing fillers for plastic and rubber
- Nanodiamonds are thermal fillers for creating thermally conductive materials
Use of Nanodiamonds in Medicine
- Nanodiamonds can shuttle chemotherapy drugs to cells without negative effects
- They surround drugs to prevent damage to healthy cells
- Nanodiamonds release drugs into cancer cells
- Leftover nanodiamonds do not induce inflammation in cells
- Nanodiamonds have potential for transforming cancer treatment
Ig Nobel 2012 Peace Prize
- SKN Company was awarded the Ig Nobel Peace Prize in 2012
- The company converted old Russian ammunition into nanodiamonds
Noteworthy Points
- Diamond yield can reach 90% depending on synthesis conditions and cooling capacity
