Haematoccocus lacustris (previously H. pluvialis) is a desiccation-tolerant unicellular freshwater green alga. During acclimation to desiccation, astaxanthin-rich lipid bodies and low-molecular-weight antioxidants (α-tocopherol, glutathione) accumulate ...

Molecular Dynamics Study of Molecular Mobility in Catenanes [PDF]
Molecular machines described in this paper are meant to be such molecular systems that make use of conformational mobility (i.e. hindered rotation around chemical bonds and molecular construction deformations with formation and breakage of nonvalent bonds). Components of molecular machines move mainly by means of restricted diffusion.

Evidence of Strong Guest–Host Interactions in Simvastatin Loaded in Mesoporous Silica MCM-41
A rational design of drug delivery systems requires in-depth knowledge not only of the drug itself, in terms of physical state and molecular mobility, but also of how it is distributed among a carrier and its interactions with the host matrix.

Molecular Mobility of Polymers at the Melting Transition
Melting of crystals is an archetypical first order phase transition. Albeit extensive efforts, the molecular origin of this process in polymers is still not clear. Experiments are complicated by the tremendous change in mechanical properties and the occurrence of parasitic phenomena masking the genuine material response.

Molecular mobility in crystallising aromatic thermoplastic polyimide R-BAPS
The molecular mobility of the thermoplastic aromatic R-BAPS polyimide films based on 1,3-bis (3,3’-4,4’-dicarboxyphenoxy) benzene (dianhydride) and 4,4’-bis (4-aminophenoxy) biphenyl was studied using the dielectric method.
