Positively charged or electron-deficient.
- 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?
- 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...
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
Compound in which an oxygen atom is bonded to two alkyl or two aryl groups, or one alkyl and one aryl group.
The study of rates and mechanisms of chemical reactions and of the factors on which they depend.
The metal ion and its coordinating ligands but not any uncoordinated counter-ions.
A decrease in the radii of the elements following the lanthanides compared to what would be expected if there were no f-transition metals.
Compound derived from a carbonic acid by replacing the --OH group with a halogen (X), usually --Cl, general formula is O R--C--X.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
Unit of electrical charge.
Reactions in which oxidation and reduction occur, also called redox reactions.
A salt or ester of xanthic acid. Many xanthates have a yellow color. Xanthates are used as flotation agents in mineral processing.
Description of the quantitative relationships among substances as they participate in chemical reactions.
The solute-like species in a colloid.
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Complex species that contain ammonia molecules bonded to metal ions.
A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.
Voltaic cells in which the reactants (usually gases) are supplied continuously.
A voltaic cell that converts the chemical energy of a fuel and an oxidizing agent directly into electriacl energy on a continuous basis.
Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.
A ligand atom whose electrons are shared with a Lewis acid.
Third Law of Thermodynamics
The entropy of a hypothetical pure, perfect, crystalline sustance at absolute zero temperature is zero.
Molecular orbital resulting from head-on overlap of two atomic orbitals.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
