Study of Molecular and Ionic Vapor Composition over CeI3 by Knudsen Effusion Mass Spectrometry

Journal of Spectroscopy, 2016
The molecular and ionic composition of vapor over cerium triiodide was studied by Knudsen effusion mass spectrometry. In the saturated vapor over CeI3 the monomer, dimer, and trimer molecules and the negative ions I−, CeI4-, and Ce2I7- were identified in

EVALUTION OF THERMODYNAMIC CHARACTERISTICS OF METAL NANOCLUSTERS VIA MOLECULAR DYNAMICS DATA [PDF]

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2013
Molecular dynamics results on transition metal nanoclusters were used to calculate the enthalpies of melting and sublimation. The values for the sublimation enthalpies (heats) demonstrate a good agreement with the tabulated values for the corresponding ...

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.

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

Nanoplastics in Depolymerization Products from Hydrolysis of Poly(Ethylene Terephthalate) in the Solid State

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 ...

Energetics for Hydrogen Atom Transfer by Ketyl Radicals: Is Thermodynamics on Your Side?

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
The classic hydrogen atom transfer from the 1900 Ciamician paper and its enthalpic changes illustrate ketyl thermodynamics. ABSTRACT Ketyl radicals play a key role in various reaction mechanisms, where their ability to donate hydrogen atoms governs numerous processes, ranging from photoredox catalysis to biological mechanisms and the synthesis of metal
