- 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?
- Use of diamonds
Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...
- Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...
- 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.
Most Popular
Hydride
A binary compound of hydrogen.
Strong Electrolyte
A substance that conducts electricity well in a dilute aqueous solution.
Distillation
The separation of a liquid mixture into its components on the basis of differences in boiling points. The process in which components of a mixture are separated by boiling away the more volitile liquid.
End Point
The point at which an indicator changes colour and a titration is stopped.
Le Chatelier's Principle
States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it.
If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.
Adsorption
Adhesion of a species onto the surfaces of particles.
Salt Bridge
A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.
Emulsifying Agent
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
Cyclotron
A device for accelerating charged particles along a spiral path.
Atomic Orbital
Region or volume in space in which the probability of finding electrons is highest.
