Doping TiO 2 with certain atoms its photocatalytic activity could be enhanced. [8] In contrast, pigment-grade TiO 2 usually has a median particle size in the 200–300 nm range. [6]: 1–2 Because TiO 2 powders contain a range of sizes, they may have a fraction of nanoscale particles even if the average particle size is larger. [9]
The final structure of the SAM is also dependent on the chain length and the structure of both the adsorbate and the substrate. Steric hindrance and metal substrate properties, for example, can affect the packing density of the film, [1] [10] while chain length affects SAM thickness. [12] Longer chain length also increases the thermodynamic ...
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4]
Protein nanotechnology is a field of research that integrates the diverse physicochemical properties of proteins with nanoscale technology. This field assimilated into pharmaceutical research to give rise to a new classification of nanoparticles termed protein (or protein-based) nanoparticles (PNPs).
Polymer-protein hybrids are a class of nanostructure composed of protein-polymer conjugates (i.e. complexes composed of one protein attached to one or more polymer chains). [1] [2] The protein component generally gives the advantages of biocompatibility and biodegradability, as many proteins are produced naturally by the body and are therefore well tolerated and metabolized. [3]
The nature of the organic group on the silanization agent strongly influences the properties of the surface. Simple alkyl-containing silanizing groups confer hydrophobicity. When side chains of the silane compound are amines or thiols, the surfaces assume the properties of those functional groups. [5]
Schematic representation of the different stages and routes of the sol–gel technology. In this chemical procedure, a "sol" (a colloidal solution) is formed that then gradually evolves towards the formation of a gel-like diphasic system containing both a liquid phase and solid phase whose morphologies range from discrete particles to continuous polymer networks.
Triton X-100 is widely used to lyse cells to extract protein or organelles, or to permeabilize the membranes of living cells. [6] Some applications include: Inactivation of lipid-enveloped viruses (e.g. HIV, HBV, HCV) in manufacturing of biopharmaceuticals; Industrial purpose (plating of metal)
