A device for measuring pressure.
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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 solution that obeys Raoult's Law exactly.
Compartment in which the oxidation or reduction half-reaction occurs in a voltaic cell.
The complex series of reactions by which nitrogen is slowly but continually recycled in the atmosphere, lithosphere and hydrosphere.
Heisenberg Uncertainty Principle
It is impossible to determine accurately both the momentum and position of an electron simultaneously.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
Spectrum that contains all wave-lengths in a specified region of the electromagnetic spectrum.
In aqueous solution, the process in which a molecular compound reacts with water and forms ions.
Absorption of a K shell (n=1) electron by a proton as it is converted to a neutron.
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.
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.
A term used to describe molecules and polyatomic ions that have one atom in center and four atoms at the corners of a tetrahedron.
Alpha (a) Particle
Helium ion with 2+ charge, an assembly of two protons and two neutrons.
Photochemically produced oxidizing agents capable of causing damage to plants and animals.
An atom in a molecule or polyatomic ion that is bonded to more than one other atom.
A measure of the amount of matter in an object. Mass is usually measured in grams or kilograms.
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
Chemical Hygiene Plan (CHP)
A written program developed and implemented by an employer designating proceedures, equipment, personal protective equipment, and work practices that are capable of protecting employees from the health hazards presented by hazardous chemicals usid in that particular workplace.
To estimate the value of a result outside the range of a series of known values. Technique used in standard additions calibration procedure.
Poor electric and heat conductor.
Molecular Orbital Theory
A theory of chemical bonding based upon the postulated existence of molecular orbitals.
