Effect of Pressure on Thermal Stability of G-Quadruplex DNA and Double-Stranded DNA Structures

Molecules, 2013
Pressure is a thermodynamic parameter that can induce structural changes in biomolecules due to a volumetric decrease. Although most proteins are denatured by pressure over 100 MPa because they have the large cavities inside their structures, the double ...

Proton Conduction via Water Bridges Hydrated in the Collagen Film

Journal of Functional Biomaterials, 2020
Collagen films with proton conduction are a candidate of next generation of fuel-cell electrolyte. To clarify a relation between proton conductivity and formation of water networks in the collagen film originating from a tilapia’s scale, we ...

Modifications induced by adding natural zeolitic pozzolans to cement paste

Materiales de Construccion, 2005
Volcanic pozzolans owe their pozzolanic activity chiefly to the presence of vitreous or zeolitic material rich in SiO2, and Al20y compounds that react with the portlandite produced during cement hydration to generate amorphous gels with cementitious ...

Hydration and Microstructure of Steel Slag as Cementitious Material and Fine Aggregate in Mortar

Molecules, 2020
Due to the low hydration activity and poor volume stability, extensive steel slag utilization is restricted. In this paper, the hydration process and microstructure of alkali-activated materials with steel slag as a cementitious material and fine ...

Cancellation between auto- and mutual correlation contributions of protein/water dynamics in terahertz time-domain spectra

Biophysics and Physicobiology, 2019
Terahertz time-domain spectra (THz-TDS) were investigated using the results of molecular dynamics (MD) simulations of Staphylococcal nuclease at two hydration states in the temperature range between 100 and 300 K.
