  2. Nanomaterials - Wikipedia

    en.wikipedia.org/wiki/Nanomaterials

    A popular method involves mechanical break apart bulk materials into nanomaterials is 'ball milling'. Besides that, nanoparticles can also be made by laser ablation which apply short pulse lasers (e. g. femtosecond laser) to ablate a target (solid).

  3. Ball mill - Wikipedia

    en.wikipedia.org/wiki/Ball_mill

    A ball mill is a type of grinder filled with grinding balls, used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

  4. Mechanical alloying - Wikipedia

    en.wikipedia.org/wiki/Mechanical_alloying

    The non-equilibrium phases synthesized include supersaturated solid solutions, metastable crystalline and quasicrystalline phases, nanostructures, and amorphous alloys.The method is sometimes is classified as a surface severe plastic deformation method to achieve nanomaterials. [3] Alloying during high-energy milling. [4]

  5. Severe plastic deformation - Wikipedia

    en.wikipedia.org/wiki/Severe_Plastic_Deformation

    During milling, particles are fractured and cold welded together, resulting in large deformations. The end product is generally a powder that must then be consolidated in some way (often using other SPD processes), but some alloys have the ability to consolidate in-situ during milling. Mechanical alloying also allows powders of different metals ...

  6. Nanomedicine - Wikipedia

    en.wikipedia.org/wiki/Nanomedicine

    The size of nanomaterials is similar to that of most biological molecules and structures; therefore, nanomaterials can be useful for both in vivo and in vitro biomedical research and applications. Thus far, the integration of nanomaterials with biology has led to the development of diagnostic devices, contrast agents, analytical tools, physical ...

  7. Nanoparticle drug delivery - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle_drug_delivery

    This is particularly problematic in top-down production of nanocrystals. Methods such as high-pressure homogenization and bead milling, tend to increase instabilities by increasing surface areas; to compensate, or as a response to high pressure, individual particles may aggregate or turn amorphous in structure. [30]

  8. Sol–gel process - Wikipedia

    en.wikipedia.org/wiki/Sol–gel_process

    The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers in solution into a colloidal solution ( sol ) that acts as the precursor for an integrated network (or gel ) of either discrete particles or network polymers .

  9. Comminution - Wikipedia

    en.wikipedia.org/wiki/Comminution

    In general medicine, it is one of the most traumatic forms of bone fracture. Within industrial uses, the purpose of comminution is to reduce the size and to increase the surface area of solids. It is also used to free useful materials from matrix materials in which they are embedded, and to concentrate minerals.
