  • 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...

  • Chemistry of the sky

    Chemistry can teach us about the composition of celestial bodies and determine their age.

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

  • Ozone

    We breathe 24 hours a day, 7 days a week, consuming about 25 kg of air every day. It turns out that we practically predetermine our health by the air we breathe.

  • Protein Design: Automated protein discovery and synthesis

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.



Most Popular

Curie (Ci)

The basic unit used to describe the intensity of radioactivity in a sample of material. One curie equals 37 billion disintegrations per second or approximately the amount of radioactivty given off by 1 gram of radium.

Boron Hydrides

Binary compounds of boron and hydrogen.

Resonance

The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.

Supercritical Fluid

A substance at temperature above its critical temperature.

Standard Entropy

The absolute entropy of a substance in its standard state at 298 K.

Electrode Potentials

Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.

yttrium metal

Any of a subgroup of rare-earth elements, of which the cerium and terbium metals comprise the other two subgroups.

Saccharic

of or derived from saccharin or a saccharine substance.

 

Conformations

Structures of a compound that differ by the extent of rotation about a single bond.

Antibonding Orbital

A molecular orbital higher in energy than any of the atomic orbitals from which it is derived, lends instability to a molecule or ion when populated with electrons, denoted with a star (*) superscript or symbol.
