We investigate, for two water models displaying a liquid-liquid critical point, the relation between changes in dynamic and thermodynamic anomalies arising from the presence of the liquid-liquid critical point. We find a correlation between the dynamic crossover and the locus of specific heat maxima C(P)(max) ("Widom line") emanating from the critical point. Our findings are consistent with a p...

Heteropoly acid promoted nanoparticle of nickel oxide samples were prepared by sol-gel method using heteropoly acids. Prepared composite was characterized by XRD, FT-IR and ICP technique. In this work, we have reported bromination of phenol, its derivatives and some aromatic compounds. The liquid phase bromination of phenol was Performed using heteropoly acids immobilized nanoparticle of nickel...

We observe few-electron bubbles in liquid helium-4, forming a soft nanomaterial with quantum interactions.

A metastable liquid may exist under supercooling, sustaining the liquid below the melting point such as supercooled water and silicon. It may also exist as a transient state in solid-solid transitions, as demonstrated in recent studies of colloidal particles and glass-forming metallic systems. One important question is whether a crystalline solid may directly melt into a sustainable metastable ...

Figure 1: A sketch of the L3 phase liquid crystal structure, derived from electron microscopy done on freeze fractured samples, as well as theoretical considerations. The pore diameters are uniform, but are randomly interconnected in all three dimensions resulting in short range order with long range disorder. The bilayer forming the liquid crystal can then be templated by a silica layer to cap...

Structural analyses were performed to determine the local structure of liquid TiCl4 using laboratory-scale X-ray diffraction and Raman spectroscopy from which the existence of tetrahedral TiCl4 molecules in the liquid was definitely confirmed. Conventionally, in molten salts, the valence increase of the central metal ion, for example in the range from 1 to 3, leads to more complicated liquid st...

In this work, we explore the inherent dynamics of liquid crystal formers using geodesic theory. We locate geodesics (shortest paths) through the potential energy landscape ensembles of the isotropic liquid and nematic liquid crystal phases of a liquid crystal forming system. One expects that the differences in properties of these paths between the liquid and liquid crystal phases will yield ins...
