The Slow Molecular Mobility in Amorphous Trehalose
ChemPhysChem, 2007AbstractThe molecular mobility in amorphous trehalose is studied by thermally stimulated depolarisation currents (TSDC). The effect of aging on the sub‐Tg motional processes was analysed during annealing at a given aging temperature, some degrees below the calorimetric glass transition temperature Tg=115 °C.

On diffusive molecular communication with mobile nanomachines
2018 52nd Annual Conference on Information Sciences and Systems (CISS), 2018This work considers the problem of diffusive molecular communication with mobile transmit and receive nanomachines. The optimal test is determined for symbol detection at the receiver nanomachine. To evaluate system performance, closed-form expressions are derived for the probabilities of detection and false alarm, probability of error, and capacity in

Methods and Applications of Mobile Molecular Communication
Proceedings of the IEEE, 2019This paper provides a comprehensive review of the emerging research area of mobile molecular communication. In mobile molecular communication, sender and receiver bionanomachines as well as associated nodes in the environment exhibit dynamic behavior in the sense that they are mobile and communicate while they move.

Effect of Water on the Molecular Mobility of Elastin
Biomacromolecules, 2004Purified and hydrated elastin is studied by both thermal and dielectric techniques to have insight into the chain dynamics of this protein. By differential scanning calorimetry, the glassy behavior of elastin is highlighted; the glass transition temperature (T(g)) of elastin is found to be widely dependent on hydration, falling from 200 degrees C in ...

Molecular mobility of nanocellulose hydrogels
Russian Journal of Physical Chemistry B, 2016The molecular mobility of nanocellulose hydrogels isolated from microcrystalline cellulose is evaluated using the spin probe method, from the correlation time τ (s) and rotational frequency ν = 1/τ(s–1) of stable nitroxyl radicals introduced into the medium under study.

Study of the molecular mobility of collagen
Journal of Polymer Science Part B: Polymer Physics, 1995AbstractThe dielectric relaxations of a biopolymer, collagen, have been studied by means of the thermally stimulated current (TSC) technique. To investigate effects of water on TSC spectra, complementary measurements by differential scanning calorimetry (DSC) have been performed.

Molecular Mobility in Supercooled Trehalose
The Journal of Physical Chemistry B, 2003The molecular mobility of amorphous anhydrous trehalose (C12H22O11) was investigated by means of temperature-modulated differential scanning calorimetry (TMDSC) and dielectric analysis (DEA). TMDSC was used to perform a specific heat spectroscopy, which appeared essential, as dielectric measurements above Tg were hampered by dc conductivity.

Molecular mobility in polyvinylfluoride and polyvinylidenefluoride
Polymer Science U.S.S.R., 1975Abstract The method of free torsional vibrations has been used to study molecular mobility in polyvinylfluoride. The α-, s- and γ-relaxation processes have been observed and investigated. An analogy has been established between relaxation processes and molecular mobility in polyvinylfluoride and the similar processes in polyethylene at low ...

Molecular Mobility in Membranes
1988The dynamic properties of membrane molecules, namely, the lipids and the proteins, can be divided into two groups: (1) lateral diffusion in the plane of the membrane, and (2) rotational diffusion, principally about the membrane normal (Fig. 1). In general the rotational motions are considerably faster than the translational motions, indicating that the
