The solvent-like phase in a colloid.
- 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 are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
- 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...
Binary compounds of boron and hydrogen.
Forces of attraction between a liquid and another surface.
A rare trivalent metallic element, found in gadolinite and other minerals. Symbol: Y, at. wt.: 88.905, at. no.: 39, sp. gr.: 4.47. Cf."rare-earth element."
Yttrium has a silver-metallic luster and is relatively stable in air unless finely divided. Turnings of the metal, however, ignite in air if their temperature exceeds 400oC. Yttrium oxide is one of the most important compounds of yttrium and accounts for the largest use. It is widely used in making YVO4 europium, and Y2O3 europium phosphors to give the red color in color television tubes.
Transition State Theory
Theory of reaction rates that states that reactants pass through high-energy transition states before forming products.
The chemistry of substances that contain carbon-hydrogen bonds.
A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.
One of the two mirror-image forms of an optically active molecule.
Very weak and very short-range attractive forces between short-lived temporary (induced) dipoles, also called dispersion Forces.
An inhibitor, a catalyst that decreases the rate of reaction.
A salt containing an ionizable hydrogen atom. Acidic salt does not necessarily produce acidic solutions.
Compounds that contain only carbon and hydrogen.
A change in which a substance changes from one physical state to another but no substances with different composition are formed. Example Gas to Liquid - Solid.
An isotope of hydrogen whose atoms are twice as massive as ordinary hydrogen,deuterion atoms contain both a proton and a neutron in the nucleus.
The pentosan occurring in woody tissue that hydrolyzes to xylose: used as a source of furfural.
An aliphatic acid, many can obtained from animal fats.
Isomers that result from the interchange of ions inside and outside the coordination sphere.
It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.
A substance of two or more elements in fixed proportions. Compounds can be decomposed into their constituent elements.
The time required for half of a reactant to be converted into product(s). The time required for half of a given sample to undergo radioactive decay.
Compounds with different arrangements of groups on either side of a bond with restricted rotation, such as a double bond or a single bond in a ring, for example cis-trans isomers of certain alkenes. Stereoisomers that are not mirror images of each other, also known as position isomers.
