Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, [1] lime, [2] lead sulfide [3] and certain minerals containing phosphorus. Iron ore was also used as a flux in the smelting of copper.
The flux method is a crystal growth method where starting materials are dissolved in a solvent (flux), and are precipitated out to form crystals of a desired compound. The flux lowers the melting point of the desired compound, analogous to a wet chemistry recrystallization. [1]
Lab notebook with the complete record of the experiments underlying a published paper. [1] Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research .
Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change. This may be done in air ...
To generate a 3-dimensional view of fluxes, the flux sensor must take measurements in the X, Y, and Z directions at each point around a sample. In 2006, a view of H + and O 2 3D flux vectors around a pollen tube was produced using Mageflux software developed by Yue Xu. [25] A breast tumor sample is measured simultaneously by H + and O 2 flux ...
This example of design experiments is attributed to Harold Hotelling, building on examples from Frank Yates. [22] [23] [15] The experiments designed in this example involve combinatorial designs. [24] Weights of eight objects are measured using a pan balance and set of standard weights. Each weighing measures the weight difference between ...
It is easiest to describe the flux of metabolites through a pathway by considering the reaction steps individually. The flux of the metabolites through each reaction (J) is the rate of the forward reaction (V f), less that of the reverse reaction (V r): [2]
MINFLUX takes advantage of this feature when localizing an active fluorophore. It records photon fluxes using a probing scheme of at least three recording points around the probing area and one point at the center. These fluxes differ at each recording point as the active molecule is excited by different light intensities.
