Flow patterns and heat transfer for flow boiling in small to micro diameter tubes [PDF]
, 2008 An overview of the recent developments in the study of flow patterns and boiling heat transfer in small to micro diameter tubes is presented. The latest results of a long-term study of flow boiling of R134a in five vertical stainless steel tubes of ...

Specific heat of Sr4Ru3O10 [PDF]
Solid State Communications, 2004 We have measured the specific heat of single crystals of the triple-layer Ruddlesden-Popper material, Sr4Ru3O10, grown both in an image furnace and by flux-growth. The flux grown sample has a sharp mean-field-like anomaly at the onset of magnetic order, Tc = 102 K, but a much broader anomaly, indicative of residual heterogeneity, is observed for the ...

Specific heat of Ca0.33Na0.67Fe2As2 [PDF]
Solid State Communications, 2014 The specific heat of single crystal hole-doped Ca0.33Na0.67Fe2As2, Tc(onset)=33.7 K, was measured from 0.4 to 40 K. The discontinuity in the specific heat at Tc, deltaC, divided by Tc is 105 +- 5 mJ/molK2, consistent with values found previously for hole-doped Ba0.6K0.4Fe2As2 and somewhat above the general trend for deltaC/Tc vs Tc for the iron based ...

Specific heat of a ferromagnetic film [PDF]
Physical Review E, 1996 We analyze the specific heat for the $O(N)$ vector model on a $d$-dimensional film geometry of thickness $L$ using ``environmentally friendly'' renormalization. We consider periodic, Dirichlet and antiperiodic boundary conditions, deriving expressions for the specific heat and an effective specific heat exponent, $α\ef$. In the case of $d=3$, for $N=1$,

Kinks in the Electronic Specific Heat [PDF]
Physical Review Letters, 2009 We find that the heat capacity of a strongly correlated metal presents striking changes with respect to Landau Fermi liquid theory. In contrast with normal metals, where the electronic specific heat is linear at low temperature (with a T^3 term as a leading correction), a dynamical mean-field study of the correlated Hubbard model reveals a clear kink ...

Temperature-dependent thermal properties of spark plasma sintered alumina [PDF]
Science of Sintering, 2017 In this work, we report temperature-dependent thermal properties of alumina powder and bulk alumina consolidated by spark plasma sintering method. The properties were measured between room temperature and 250ºC using a thermal constants analyzer.

Magnetization, Band Gap and Specific Heat of Pure and Ion Doped MnFe2O4 Nanoparticles
Magnetochemistry, 2023 We have studied the magnetic properties of ion doped MnFe2O4 nanoparticles with the help of a modified Heisenberg model and Green’s function theory taking into account all correlation functions.

The impact of heat waves on mortality. [PDF]
, 2011 BACKGROUND: Heat waves have been linked with an increase in mortality, but the associated risk has been only partly characterized. METHODS: We examined this association by decomposing the risk for temperature into a "main effect" due to independent ...
