    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?

  • 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...

  • 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...

    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.



Most Popular

Thermodynamics

The study of the energy transfers accompanying physical and chemical processes.

xanthate

A salt or ester of xanthic acid. Many xanthates have a yellow color. Xanthates are used as flotation agents in mineral processing.

Quantum Mechanics

Mathematical method of treating particles on the basis of quantum theory, which assumes that energy (of small particles) is not infinitely divisible.

Free Energy, Gibbs Free Energy

The thermodynamic state function of a system that indicates the amount of energy available for the system to do useful work at constant T and P.

Colligative Properties

Physical properties of solutions that depend upon the number but not the kind of solute particles present.

Radical

An atom or group of atoms that contains one or more unpaired electrons (usually very reactive species)

Photochemical Oxidants

Photochemically produced oxidizing agents capable of causing damage to plants and animals.

Bubbles

Have you ever noticed that soap bubbles go up in winter and fall down in summer? The reason is that warm air is lighter than cold. And in winter the difference between the air temperature in the room (especially near the windows) and the one you exhale into the bubble is enough to overcome the heaviness of its shell.

Base

A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.

Water Equivalent

The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase.
