Hierarchy of fast motions in protein dynamics
Article Abstract:
Time step limiting factors were analyzed in a series of numerical tests by using an internal coordinate molecular dynamics approach to investigate the hierarchy of fast motions in proteins. The molecular dynamics approach allows the selected internal coordinates to be frozen. Experimental results showed that there exists a complicated hierarchy of fast motions in proteins, with both harmonic and anharmonic effects mixed together at several close time scales.

A remarkable elevation of freezing temperature of CCl4 in graphitic micropores
Article Abstract:
Differential scanning calorimetry was used to examine the behavior of CCl4 confined in graphitic micropores of activated carbon fibers (ACF) over the temperature range of 180 to 320 K. A clear peak was observed for ACF of average pore width, w = 1.1 nm which showed that freezing temperature was 299 K. The freezing temperature was raised by 57 K. However, only 1.0% of that of the bulk liquid CCl4 to an fcc solid phase was measured in the enthalpy of freezing.
