L4#synthesis of nanoparticles

Nanoscience

The study of structures and materials on the nanoscale, typically between 1 and 100 nanometers.

Nanotechnology

The application of nanoscience to create new materials and devices with unique properties.

Nanoparticles (NPs)

Particles that are between 1 and 100 nanometers in size, exhibiting unique physical and chemical properties.

Synthesis of Nanomaterials

The process of creating nanomaterials through various methods and approaches.

Top-Down Approach

A method of synthesizing nanomaterials that starts with larger particles and reduces them to nanoscale through various processes.

Bottom-Up Approach

A method of synthesizing nanomaterials that builds them up from atomic or molecular components.

Nucleation

The initial process where small particles or nuclei form, which can grow into larger structures.

Monodispersed Particles

Nanoparticles that are uniform in size and shape.

Polydispersed Nanoparticles

Nanoparticles that vary in size and shape.

Mechanical Method

A physical method of nanoparticle synthesis that includes techniques like ball milling and melt mixing.

Ball Milling

A mechanical method where materials are ground into nanoparticles using hard balls in a rotating container.

Melt Mixing

A method of forming nanoparticles by cooling a liquid mixture to create an amorphous solid.

Pulse Laser Ablation

A physical method where a high-pulsed laser beam is focused on a target to create nanoparticles.

Pulsed Wire Discharge Method (PWD)

A technique for synthesizing nanoparticles by vaporizing a metal wire with a pulsed current.

Chemical Vapor Deposition

A chemical method for producing thin films and nanoparticles through chemical reactions in vapor phase.

Sol-gel Method

A chemical synthesis technique that involves transitioning from a liquid solution to a solid gel phase.

Sonochemical Synthesis

A method that uses ultrasonic waves to induce chemical reactions for nanoparticle formation.

Hydrothermal Synthesis

A chemical method that uses high-pressure and high-temperature water to synthesize nanoparticles.

Biological Methods

Techniques for synthesizing nanoparticles using biological organisms or extracts.
