Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...
Polymer blends can be broadly divided into three categories: immiscible polymer blends (heterogeneous polymer blends): This is by far the most populous group. If the blend is made of two polymers, two glass transition temperatures will be observed.
The basic properties of solutions are as drafted under: [citation needed] All solutions are the examples of homogeneous mixture. The particles of a homogeneous mixture are less than one nanometre in size. A homogeneous mixture does not show Tyndall effect. The constituent of homogeneous mixture cannot be separated using centrifugation or ...
The introduction equates homogeneous mixtures with solutions, in defiance of the rest of the article. This article says colloids are "both" homogeneous and heterogeneous. Now, they may exhibit characteristics of both types, but that doesn't matter. Homogeneity and heterogeneity, as defined here, seem mutually exclusive.
In statistics, homogeneity and its opposite, heterogeneity, arise in describing the properties of a dataset, or several datasets.They relate to the validity of the often convenient assumption that the statistical properties of any one part of an overall dataset are the same as any other part.
Adsorption is the process by which a gas (or solution) phase molecule (the adsorbate) binds to solid (or liquid) surface atoms (the adsorbent). The reverse of adsorption is desorption, the adsorbate splitting from adsorbent. In a reaction facilitated by heterogeneous catalysis, the catalyst is the adsorbent and the reactants are the adsorbate.
A colloid is a heterogeneous mixture where the dispersed particles have at least in one direction a dimension roughly between 1 nm and 1 μm or that in a system discontinuities are found at distances of that order. [8] A suspension is a heterogeneous dispersion of larger particles in a medium. Unlike solutions and colloids, if left undisturbed ...
The nanofibres, nanocomposites, hollow nanofibres, core–shell nanofibres, and nanorods or nanotubes produced have a great potential for a broad range of applications including homogeneous and heterogeneous catalysis, dental restorative materials, [4] [5] sensorics, filter applications, and optoelectronics. Here we will just consider a limited ...
