    Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?

  3. CAP theorem - Wikipedia

    en.wikipedia.org/wiki/CAP_theorem

    Note that consistency as defined in the CAP theorem is quite different from the consistency guaranteed in ACID database transactions. [4] Availability Every request received by a non-failing node in the system must result in a response. This is the definition of availability in CAP theorem as defined by Gilbert and Lynch. [1]

    Jacobus van 't Hoff (1852–1911), an influential theoretical chemist and the first winner of the Nobel Prize in Chemistry.. Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular ...

  8. Quadrupole ion trap - Wikipedia

    en.wikipedia.org/wiki/Quadrupole_ion_trap

    The linear form of the trap can be used as a selective mass filter, or as an actual trap by creating a potential well for the ions along the axis of the electrodes. [12] Advantages of the linear trap design are increased ion storage capacity, faster scan times, and simplicity of construction (although quadrupole rod alignment is critical ...

    en.wikipedia.org/wiki/Clausius–Clapeyron_relation

    On a pressure–temperature (P–T) diagram, for any phase change the line separating the two phases is known as the coexistence curve.The Clapeyron relation [6] [7] gives the slope of the tangents to this curve.
