We numerically investigate the necessary ingredients for reentrant behavior in the phase diagram of physical systems. Studies on the possibly simplest model that exhibits reentrance, the two-dimensional random-bond Ising model, show that reentrant behavior is generic whenever frustration is present in the model. For both discrete and continuous disorder distributions, the phase diagram in the d...

We report the crystal structure and dielectric properties of a pure H2O@C60 crystal at low temperature. The caged water molecules free from the hydrogen bonds rotate even at 8 K. The antifreeze rotating water molecules respond to an external electric field due to their permanent dipole moment.

cold hardiness is one of the most common adaptations of insects at low temperatures. to understand the cold hardiness strategy of beet armyworm, spodoptera exigua (hübner), six temperature treatments were tested on the last instar larvae. supercooling points of treatments were not significantly different. two sugars, glucose and trehalose, as well as three polyols, myo-inositol, glycerol and so...

background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

We report a first-order structurally-driven Mott transition a t T=357 K in single crystal Ca2RuO4, an isomorph to the superconductor Sr2RuO4. A discontinuous jump in electrical resistivity with a concomitant change in magnetic moment is triggered by a pronounced structural transition from a high temperature tetragonal phase to a low temperature orthorhombic phase. We argue that t h e elastic en...
