• In the superconducting state, a large residual linear term is observed in the thermal conductivity, in quantitative agreement with BCS theory for a d-wave superconductor [4].
• We have measured the transverse thermal conductivity kappa(xy) of twinned and untwinned YBa(2)Cu(3)O(7) single crystals as a function of angle theta between the magnetic field applied parallel to the CuO(2) planes and the heat current direction [5].
• The thermal conductivity data present a T-linear term consistent with the universal limit (CeIrIn5), and a low temperature T3 variation in the clean limit (CeCoIn5), also in accord with prediction for an unconventional superconductor with lines of nodes [6].

• A thermal conductivity detector was employed for continuous measurement of inhalation chamber ethanol vapor concentration [7].

Anatomical context of Thermal Conductivity

• Using this technique, the thermal conductivity and diffusivity of two organ perfusates (HP5 and HP5 + 2M glycerol), one kidney phantom (a low ionic strength gel), as well as rabbit kidney cortex have been measured from -10 degrees C to -70 degrees C [8].

Associations of Thermal Conductivity with chemical compounds

• As organic solvents have lower thermal conductivity than water (methanol and acetonitrile, e.g., nearly by a factor of 3) it can be hypothesized that the temperature gradient inside the capillary is more pronounced in organic solvents compared to an aqueous solution [9].
• Helium detectors utilizing thermal conductivity are sensitive to the presence of nitrous oxide (N2O) and oxygen (O2) [10].
• With optimized crystal quality and coatings, lithium selenoindate should show superior performance as compared with AgGaS(e)2 crystals, owing to its 4x larger thermal conductivity [11].
• The thermal conductivities of gypsum- and phosphate-bonded investments at high temperatures were accurately measured by means of the hot wire method [12].
• Beta zeolite supported on silicon carbide, with high thermal conductivity and high mechanical strength, was successfully used as an active and stable catalyst for Friedel-Crafts reactions in a fixed bed configuration [13].

• It is demonstrated that 2% Yb: CaGdAlO4 (called CAlGO) presents favorable thermomechanical properties with a high measured thermal conductivity (Kc = 6.3 and Kc = 6.9 W m(-1) K(-1) [14].
• Thermal conductivity and diffusivity of neuroblastoma tumor [15].
• A very small amount of sulfuric acid (volume of 0.5 ml, concentration of 2 mol/l) is used to acidify a sample of less than 300 microl in volume and convert the dissolved carbonate into carbon dioxide (gas) in a sample vial (reactor) that is analyzed by thermal conductivity detection through a headspace sampler [16].
• In our laboratory three methods to analyze COHb in post-mortem blood samples were compared: the spectrophotometric method of Maehly, a gas chromatographic method with a thermal conductivity detector (GC-TCD) and the Oximeter [17].
• Low surface thermal conductivity of 0.11 W/(m K) was measured for the IR receptor surfaces as compared to the nonspecific skin areas [18].

Analytical, diagnostic and therapeutic context of Thermal Conductivity

• This system allows on-line breath sample collection from a metabolic cage, purification by gas chromatography, determination of CO2 by thermal conductivity detection and measurement of 13CO2 enrichment by isotope ratio mass spectrometry [19].
• Oriented absorption and fluorescence spectra, refractive indices, thermal expansion, and thermal conductivities are reported for the anisotropic laser material ytterbium-doped potassium gadolinium tungstate, Yb3+:KGd(WO4)2 [20].
