A thermochemical and theoretical study of the phenylpyridine isomers [PDF]
, 2000 The standard (p° = 0.1 MPa) molar enthalpies of formation for 2-, 3-, and 4-phenylpyridine in the gas phase were derived from the standard molar enthalpies of combustion, in oxygen, at 298.15 K, measured by static bomb combustion calorimetry.

Vapor pressure and sublimation enthalpy of elemental technetium
Journal of the Less Common Metals, 1980 Abstract The vapor pressure of technetium metal was measured over the temperature range 2051–2348 K using Knudsen effusion mass spectrometry. The vapor pressure of technetium measured over this temperature range is R In P(atm) = {− (128.1 ± 1.5) × 10 3 T} + (23.19 ± 0.68) .

A fully 3-dimensional thermal model of a comet nucleus [PDF]
, 2007 A 3-D numerical model of comet nuclei is presented. An implicit numerical scheme was developed for the thermal evolution of a spherical nucleus composed of a mixture of ice and dust. The model was tested against analytical solutions, simplified numerical

Macromolecular Rapid Communications, Volume 47, Issue 8, 17 April 2026.Hydrolysis of PET in the solid generates nanoparticles, but thermal signatures of PET were only observed for hydrolysis at 150°C, while oligomers appeared to dominate the non‐monomeric products from hydrolysis at higher temperatures. ABSTRACT Circularity in plastic waste management through depolymerization to monomer is a promising route to address ...
