The enthalpies of combustion and formation of linear polyethylene
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1974 The enthalpies of combustion and formation of two samples of linear polyethylene which differ only in the degree of crystallinity have been determined in an oxygen bomb calorimeter. For the two samples the degree of crystallinity, the enthalpy of combustion at 298.15 K, and the enthalpy of formation at 298.15 K, were respectively: 72 percent, -651.16 ±

Properties of air and combustion products of fuel with air [PDF]
, 1975 Thermodynamic and transport properties have been calculated for air, the combustion products of natural gas and air, and combustion products of ASTM-A-1 jet fuel and air. Properties calculated include: ratio of specific heats, molecular weight, viscosity,

Influence of diesel surrogates on the behavior of simplified spray models [PDF]
, 2012 Numerous experimental investigations make use of diesel surrogates to make the computational time reasonable. In the few studies where measured (surrogate and real diesel) and computed (surrogate only) results have been compared, the selection ...

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons
Advanced Materials, EarlyView.Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Advanced Materials, EarlyView.This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

The Journal of Chemical Thermodynamics, 2000 The standard(po = 0.1 MPa) molar enthalpies of formation for liquid 1-phenylimidazole (1PhIMI) and 1-phenylpyrazole (1PhPYR) were derived from the standard molar enthalpies of combustion, in oxygen, at T = 298.15 K, ΔcHmo, measured by static bomb combustion calorimetry. The molar heat capacities of both liquids were measured, in the temperature range

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions
Advanced Materials, EarlyView.Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...
