Compositional Mapping. A new technique of compositional mapping by electron probe microanalysis Q) has been applied to characterize the compositional microstructure of the samples. Electron probe compositional mapping involves the use of computer-aided microscopy for the construction of images in which the displayed gray scale is related to the true composition of the specimen and not merely to X-ray intensity. 

To characterize dendrimers, analytical methods used in synthetic organic chemistry as well as in macromolecular chemistry can be applied. Mass spectrometry and NMR spectroscopy are especially useful tools to estimate purity and structural perfection. To get an idea of the size of dendrimers, direct visualization methods such as atomic force microscopy (AFM) and transmission electron microscopy (TEM), or indirect methods such as size exclusion chromatography (SEC) or viscosimetry, are valuable. Computer aided simulation also became a very useful tool not only for the simulation of the geometry of a distinct molecule, but also for the estimation of the dynamics in a dendritic system, especially concerning mobility, shape-persistence, and end-group disposition. 

How do the newer disciplines like Computer-aided physico-chemical methods, tracer techniques, genetic engineering, biotechnology and electron microscopy have evolved a new direction to expatiate the intricacies of drug interaction sequel to drug design Explain. 

Students planning careers in optical glass take general classes such as calculus, physics, and chemistry. Course work on topics such as thermodynamics, microscopy, spectroscopy, and computer-aided design are also standard parts of an optical engineer s education. 

There are a number of modern violin makers who produce instruments with many of the characteristics that make the old Italian violins so desirable. If they are not prized as highly this may be due to perception rather than reality. Recently, there have been a number of efforts on the part of scientists, including chemists, to reproduce or equal the products of the Cremonese masters. In this endeavor they are making use of a battery of techniques including electron microscopy and fourier analysis of the sounds produced. Computer-aided design and manufacture are also utilized. 

The experimental analysis of particulate-filled nanocomposites butadiene—styrene mbber/fullerene-containing mineral (nanoshungite) was fulfilled with the aid of force-atomic microscopy, nanoindentation methods, and computer treatment. The theoretical analysis was carried out within the frameworks of fractal analysis. It has been shown that interfacial regions in the aforementioned nanocomposites are the same reinforcing element as nanoliller. The conditions of the transition from nano to microsystems were discussed. The fractal analysis of nanoshungite particles aggregation in polymer matrix was performed. It has been shown that reinforcement of the studied nanocomposites is a true nanoeffect.
