DEFINITIONS. • Agitation: It refers to the induced motion of a “homogenous” material in a specified way Mixing: It is the random distribution, into and through one another, of two or more initially separate phases. PURPOSES OF AGITATION.
SEPARATION TECHNIQUES. If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered:
Linchpin analysis helps analysts to identify the key assumptions that could make or break their view of a focal situation. Until the early 1990s the CIA had predominantly used ‘post-mortem’ analysis to review deficiently foreseen events. It was born of the need for a more pro-active approach.
Outline. Molecular dynamics (MD): The basic idea. Equations of motion. Key properties of MD simulations. Sample applications. Limitations of MD simulations. Software packages and force fields. Accelerating MD simulations. Monte Carlo simulation.
How can we use the laws of mechanics that describe the motions and interactions of individual atomic particles to predict macroscopic properties of the system such as pressure, volume, and temperature? In principle, each point-like atomic particle can be specified by its position and velocity (neglecting any internal structure).
4 lis 2021 · Here we report a visible-light-mediated and transition metal-free conjunctive olefination that uses an alkene ‘linchpin’ with a defined geometry to cross-couple complex molecular scaffolds that...
CHAPTER 8. Electrochemistry – II: Ion Transport in Solutions. Ionic Movement Under the Influence of an Electric Field. In order to imagine the conduction process in electrolytic solutions at the atomic level, we can follow two approaches which are somewhat different in their initial assumptions.
