Detonation nanodiamond

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
