Nanotechnology can be applied in the production, processing, safety and packaging of food. A nanocomposite coating process could improve food packaging by placing anti-microbial agents directly on the surface of the coated film. Nanocomposites could increase or decrease gas permeability of different fillers as is needed for different products.
Nanomaterials have also been applied in a range of industries and consumer products. Mineral nanoparticles such as titanium-oxide have been used to improve UV protection in sunscreen . Phosphorus, carbon and nitrogen doped titanium-oxide nanoparticles are used as additive to water based paint for self-cleaning properties. [ 44 ]
Understanding the composite nanostructures of such materials and exploring nanomaterials' different applications may lead to the development of new materials with expanded properties, such as electrical conductivity as well as temperature-, moisture- and stress-sensing abilities. [10]
Nanofibers were first produced via electrospinning more than four centuries ago. [28] [29] Beginning with the development of the electrospinning method, English physicist William Gilbert (1544-1603) first documented the electrostatic attraction between liquids by preparing an experiment in which he observed a spherical water drop on a dry surface warp into a cone shape when it was held below ...
These products were limited to bulk applications of nanomaterials and did not involve atomic control of matter. Some examples include the Silver Nano platform for using silver nanoparticles as an antibacterial agent , nanoparticle -based sunscreens, carbon fiber strengthening using silica nanoparticles, and carbon nanotubes for stain-resistant ...
A porous medium or a porous material is a material containing pores (voids). The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid (liquid or gas). There are many natural nanoporous materials, but artificial materials can also be manufactured.
Structural properties can also be used to distinguish between various hybrid materials. An organic moiety containing a functional group that allows the attachment to an inorganic network, e.g. a trialkoxysilane group, can act as a network modifier because in the final structure the inorganic network is only modified by the organic group ...
Nanomaterials are materials with a size ranging from 1 to 100 nm in at least one dimension. At the nanoscale, material properties become different. These unique properties can be exploited for a variety of applications, including the use of nanoparticles in skincare and cosmetics products.
