  2. Stöber process - Wikipedia

    en.wikipedia.org/wiki/Stöber_process

    Stöber process. The Stöber process is a chemical process used to prepare silica (SiO. 2) particles [1] of controllable and uniform size [2] for applications in materials science. It was pioneering [3] when it was reported by Werner Stöber and his team in 1968, [1] and remains today the most widely used wet chemistry synthetic approach to ...

  3. Nanoparticle deposition - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle_deposition

    Nanoparticle coating of polystyrene nanoparticles on quartz prepared with the Langmuir-Blodgett method. Nanoparticle deposition refers to the process of attaching nanoparticles to solid surfaces called substrates to create coatings of nanoparticles. The coatings can have a monolayer or a multilayer and organized or unorganized structure based ...

  4. Alkali–silica reaction - Wikipedia

    en.wikipedia.org/wiki/Alkali–silica_reaction

    Alkali–silica reaction. Characteristic crack pattern associated with the alkali–silica reaction affecting a concrete step barrier on a US motorway. Note the typical fatty aspect of the silicagel exudations imbibing the concrete surface along the two sides of the cracks. [1][2] The alkali–silica reaction (ASR), also commonly known as ...

  5. Nanosphere lithography - Wikipedia

    en.wikipedia.org/wiki/Nanosphere_lithography

    Polystyrene nanoparticle coating done with the Langmuir-Blodgett method. Langmuir-Blodgett is a deposition method in which the nanoparticles are placed in a Langmuir-Blodgett Trough floating on an aqueous solution, forming a monolayer. With the help of barriers and surface pressure sensor, the particles are compressed into the desired packing ...

  6. Self-healing concrete - Wikipedia

    en.wikipedia.org/wiki/Self-healing_concrete

    Self-healing concrete. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.

  7. Concrete sealer - Wikipedia

    en.wikipedia.org/wiki/Concrete_sealer

    Concrete sealer. Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing. [1]
