The liquid-gas phase transition in finite nuclei is studied in a heated liquid-drop model where the drop is assumed to be in thermodynamic equilibrium with the vapour emanated from it. Changing pressure along the liquid-gas coexistence line of the systems, symmetric or asymmetric, suggests that the phase transition is a continuous one. This is further corroborated from the study of the thermal ...

Several techniques have already been developed for synthesising silicon carbide (SiC) material in the form of nanospheres and nanowires/rods. Here, we report the synthesis of a distinctly different kind of SiC nanostructure in the form of three-dimensional crystalline nanowire based flower-like structures and arrays of coaxial rods. Interest in such structures centres around the combination of ...

Hydrocarbons in air were determined at pioneering European service stations equipped with vapour recovery systems. Vapour recovery was found capable of eliminating 99% of exposure during refuelling and greater than 95% of emissions to air. Vapour recovery is now being rapidly introduced at Swedish service stations as a result of demands concerning environmental and health hazards. The analytica...
