Glasses, supercooled liquids and proteins share common properties, in particular the existence of an energy landscape and the presence of two types of fluctuations, α and β. While the effect of α fluctuations on proteins has been known for a few years, the effect of β fluctuations has not been fully understood. By com…

Nanoscale surface patterning is of great importance for applications ranging from catalysts to biomaterials. We show the formation of ordered nanoscale dimple arrays on titanium, tungsten, and zirconium during electropolishing, demonstrating versatility of a process previously only reported for tantalum. This is a rar…

A terahertz time-domain spectroscopic study was carried out as an effective measure to analyze the mechanism that induces superior properties in polyamide-6 nanocomposites. The peak frequency of dielectric loss appearing at about 3.0 THz shifts to a lower frequency by the presence of clay nanofillers, while it is inde…

Multiwall WS(2) nanotube templates were used as hosts to prepare core-shell PbI(2)@WS(2) nanotubes by a capillary-wetting method. Conformal growth of PbI(2) layers on the inner wall of the relatively wide WS(2) nanotubes (i.d. ca. 10 nm) leads to nanotubular structures which were not previously observed in narrow carb…

The conversion kinetics of an aqueous gelatin solution to gel was studied by temperature modulated and regular DSC under isothermal and continuous cooling conditions. Isothermal runs revealed a decrease in the quasi-static heat capacity primarily associated with syneresis (phase separation) of the gel. Above 19 degree…

High-resolution thermal expansion measurements have been performed for exploring the mysterious "structureless transition" in (TMTTF)2X (X=PF(6) and AsF6), where charge ordering at T(CO) coincides with the onset of ferroelectric order. Particularly distinct lattice effects are found at T(CO) in the uniaxial expansivit…

Neodymium (Nd):Y 3 Al 5 O 12 (YAG) ceramics of excellent transparency have been fabricated by solid‐reactive sintering, using nanosized γ‐Al 2 O 3 and Y 2 O 3 powders as the starting materials. Reaction sequences and sintering behaviors of the powder mixture were characterized by X‐ray diffractometry and dilatometry.…

Abstract ZnO nanostructures have attracted great attention for possible applications in optoelectronic and spintronic devices. The electrical resistivity because of carriers can be improved by the introduction of Li ions, as Li is a possible dopant for achieving p‐type ZnO. We have carried out a comprehensive micro‐Ra…

ZnO nanorods/Au nanocomposites with Au nanocrystals growing at tips of ZnO nanorods or located along the surface of the nanorods can be synthesized via a facile low-cost solution method. The number of Au nanoparticles grown on ZnO nanorods can be controlled by tuning the molar ratio of ZnO to HAuCl 4; thus, the ZnO/Au…

We have studied the interplay of valley polarization and the Coulomb interaction on the energy spectrum, persistent current, and optical absorption of a graphene quantum ring. We show that the interaction has a dramatic effect on the nature of the ground state as a function of the magnetic flux and that the absence of…

Abstract With the aim of achieving ‘tailor‐made’ chitosan films, the effects of several variables on the properties of chitosan films were studied. These variables were chitosan concentration and molecular weight of thermally depolymerized chitosan, addition of lipids (palmitic acid, beeswax or carnauba wax) and plast…

Substrates for surface-enhanced Raman spectroscopy (SERS) have suffered from low enhancement, short shelf time, and poor uniformity or reproducibility. We report an effective method to produce SERS substrates that can potentially overcome these shortcomings. The SERS substrate consists of a layer of 100 nm Ag film dep…
