Nonequilibrium magnetic properties of the mixed spin (1/2, 1) Ising nanowire with core-shell structure v

Deviren, Bayram (Physica E: Low-dimensional Systems and Nanostructures, 2020-06-01)

The nonequilibrium magnetic properties (phase transition temperatures, phase diagrams, hysteresis loop areas and correlations) are investigated in the kinetic mixed spin (1/2, 1) Ising nanowire system under the time varying ...
Temperature dependency of thermal conductivity of solid phases for fatty acids; lauric, myrsistic, pivalic and stearic acids

Bayram, Ümit; Aksöz, Sezen; Maraşlı, Necmettin (JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY, 2014)

Thermal conductivity variations with tempera ture of solid phases for lauric acid (LA), myristic acid (MA), pivalic acid (PA), and stearic acid (SA) have been measured with radial heat-flow method. Temperature dependencies ...
Temperature dependency of thermal conductivity of solid phases for naphthol, camphene, salol, and benzy

Bayram, Ümit; Aksöz, Sezen; Maraşlı, Necmettin; Keşlioğlu, Kazım (JOURNAL OF THERMOPHYSICS AND HEAT TRANSFER, 2016)

Dependencies of thermal conductivity of solid phases on temperature have been investigated by using radial heat flow apparatus for naphthol, camphene, salol, and benzil. From graphs of the solid phase’s thermal ...
