Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.
- 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?
- 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...
- 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...
The mass percent of each element in a compound.
A very slightly soluble compound.
The temperature at which liquid and solid coexist in equilibrium, also the freezing point.
Liquefaction of vapor.
Homogeneous mixture of two or more substances.
Ratiation extraneous to an experiment. Usually the low-level natural radiation form cosmic rays and trace radioactive substances present in our environment.
Theory of reaction rates that states that effective collisions between reactant molecules must occur in order for the reaction to occur.
Faraday's Law of Electrolysis
One equivalent weight of a substance is produced at each electrode during the passage of 96,487 coulombs of charge through an electrolytic cell.
A device for accelerating charged particles along a spiral path.
The ability to react with both acids and bases.Ability of substance to act as either an acid or a base.
A device used to measure the heat transfer between system and surroundings.
One faraday of electricity corresponds to the charge on 6.022 x 1023 electrons, or 96,487.301 coulombs.
A piece of volumetric glassware, usually graduated in 0.1-mL intervals, that is used to deliver solutions to be used in titrations in a quantitative (dropwise) manner.
All orbitals of a given sublevel must be occupied by single electrons before pairing begins.
The particle pressure of a vapor at the surface of its parent liquid.
A Lewis base in a coordination compound.
Water containing deuterium, a heavy isotope of hydrogen.
A colorless, crystalline compound, XeF6, that melts at 50°C to a yellow liquid, and boils at 75°C.
A pattern of arrangement of particles in a crystal.
Discovered : by Sir William Ramsay in London, and independently by P.T. Cleve and N.A. Langlet in Uppsala, Sweden in 1895.
Origin : The name is derived from the Greek ‘helios’,sun.
Description :A colourless, odourless gas that is totally unreactive. It is extracted from natural gas wells, some of which contain gas that is 7% helium. It is used in deep sea diving for balloons and, as liquid helium, for low temperature research. The Earth’s atmosphere contains 5 parts per million by volume, totalling 400 million tons, but it is not worth extracting it from this source at present.
