The mechanism responsible for the loss of these symmetries is a generalization of the vacuum angle mechanism for the same effect. An important result of the present analysis is the demonstration that geometric shapes, molecules i... 展开

Why are the shapes of molecules important? What properties distinguish molecular compounds from other materials? Explain why the the structure of a molecule/compound is important. Explain what is meant by the following statement: "The properties of the substances around ...
crystal: culture crystal refers to the use of natural crystal seeds, and then give the natural crystal growth of high-pressure conditions, there are rich in silica in the breeding of molecules. Then the silica molecule grows around the natural crystal, so that the crystalline component ...
What is the difference between monosaccharides and disaccharides? What are some examples of them? Why are polysaccharides not broken down into monosaccharides by one enzyme? Explain how enzymes are able to differentiate between two molecules that have similar shapes and chemical groups like valine and...
According to the Valence-Shell Electron-Pair Repulsion Model, widely accepted among chemists since its development in the 1950s, the repulsion between electron pairs shapes the molecule in such a way as to reduce the repelling energy, or maximize the dis
background removal can rely on the detection of geometric shapes such as planes, cylinders, or cones which may correspond to a surface, the main stem, or a pot, respectively. Points can then be discarded depending on the relative position to these features. Detection of geometric shapes is of...

The study highlights the potential of in silico models to effectively identify biologically active nanoforms based on their physico-chemical properties, reinforcing previous knowledge on the relevance of certain properties, such as aspect ratio. The potential of implementing in vitro methods into NGRA is...
Brain cells release neurotransmitters, molecules that carry information from one nerve cell to another across small gaps called synapses. When they arrive at another cell, neurotransmitters cause ion channels to open, which in turn triggers the electrical impulses that pass messages along nerve fibers...
