The material in a distillation apparatus that is collected in the receiver.
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
Reactions in which one element displaces another from a compound.
Number of moles of a solute that dissolve to produce a litre of saturated solution.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
How closely a measured value agrees with the correct value.
Positively charged or electron-deficient.
A heterogeneous mixture in which solute-like particles do not settle out.
Any of six isomeric compounds that have the formula C8H11N, are derivatives of xylene, and resemble aniline: used in dye manufacture.
Two peaks or bands of about equal intensity appearing close together on a spectrogram.
A thermometer used for accurate measurement of very small changes in temperature.
The amount of matter that would be converted into energy if an atom were formed from constituent particles.
The process in which a heavy nucleus splits into nuclei of intermediate masses and one or more protons are emitted.
A measure of the relative tendency of an atom to attract electrons to itself when chemically combined with another atom.
Polymeric organosilicon compounds, contain individual or cross-linked Si-O chains or rings in which some oxygens of SiO4 tetrahedra are replaced by other groups.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
A favourable interaction of two electrons with opposite m , values in the same orbital.
A heavy, colorless, chemically inactive, monatomic gaseous element used for filling radio, television, and luminescent tubes. Symbol: Xe, at. wt.: 131.30, at. no.: 54.
Describes processes that release heat energy.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
A colorless, crystalline pentose sugar, C5H10O5, derived from xylan, straw, corncobs, etc., by treating with heated dilute sulfuric acid, and dehydrating to furfural if stronger acid is used.
A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.
