Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Enthalpy of Sublimation in the Study of the Solid State of Organic Compounds. Application to Erythritol and Threitol [PDF]

, 2005
The enthalpies of sublimation of erythritol and l-threitol have been determined at 298.15 K by calorimetry. The values obtained for the two diastereomers differ from one another by 17 kJ mol-1.

Computational Design and Theoretical Evaluation of Novel Heterocyclic Energetic Materials Based on 5‐H‐Imidazo‐[4,5‐c]‐Pyridazine and 1,2,4‐Triazolo‐[4,3‐a]‐Pyrazine Scaffolds

Journal of Computational Chemistry, Volume 47, Issue 23, September 5, 2026.
Eighty‐eight novel energetic compounds based on 5‐H‐imidazo‐[4,5‐c]pyridazine and 1,2,4‐triazolo‐[4,3‐a]pyrazine scaffolds, functionalized with nitro, nitramino, azido, and nitrate ester groups, were theoretically evaluated by DFT. Nine candidates surpassed RDX in density and detonation performance while maintaining acceptable impact sensitivity.

Resolving passive heat transfer and phase‐change heat in cryogenic CO2 deposition (Desublimation) from CO2/N2 mixtures

AIChE Journal, Volume 72, Issue 9, September 2026.
Abstract In cryogenic CO2 desublimation systems where phase change dominates both heat transfer and separation, conventional lumped thermal‐resistance treatments embed interfacial latent heat into an overall heat‐transfer coefficient, obscuring how phase‐change heat is partitioned between the gas phase and the coolant and limiting diagnostic insight ...

Solid Vapor Pressure and Enthalpy of Sublimation for Ammonium Perfluorooctanoate

, 2016
A modified gas saturation method was used to directly determine the solid vapor pressure of ammonium perfluorooctanoate (APFO). Measurements were made over the temperature range from (45 to 60) °C. Pressures ranged from (0.04 ± 0.007) Pa to (0.17 ± 0.028)

Are the sublimation thermodynamics of organic molecules predictable? [PDF]

, 2016
We compare a range of computational methods for the prediction of sublimation thermodynamics (enthalpy, entropy and free energy of sublimation). These include a model from theoretical chemistry that utilizes crystal lattice energy minimization (with the ...
