Valence bond designation for a complex in which the metal ion utilizes d orbitals for one shell inside the outermost occupied shell in its hybridization.
- 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...
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- 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...
- 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?
A type of geometrical isomerism related to the angles between like ligands.
Liquefaction of vapor.
Physical properties of solutions that depend upon the number but not the kind of solute particles present.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
A measure of the amount of matter in an object. Mass is usually measured in grams or kilograms.
Differential Scanning Calorimetry (DSC)
A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.
A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.
Law of Definite Proportions (Law of Constant Composition)
The law stating that a pure substance will always have the same percent by weight. Different samples of a pure compound always contain the same elements in the same proportions by mass.
Water containing deuterium, a heavy isotope of hydrogen.
Formula that indicates the actual number of atoms present in a molecule of a molecular substance.
The particle pressure of a vapor at the surface of its parent liquid.
A gas or mixture of gases having, in a container an absolute pressure exceeding 40 psi at 21.1°C (70°F)
A thermodynamic state or property that measures the degree of disorder or randomness of a system.
Colloidal suspension of a solid dispersed in a liquid, a semirigid solid.
Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
The pressure exerted by one gas in a mixture of gases.
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
An inhibitor, a catalyst that decreases the rate of reaction.
The heat content of a specific amount of substance, defined as E= PV.
