Galilean relativity, special relativity and the work-kinetic energy theorem revisited [PDF]

arXiv, 2007
Transformation equations for the kinetic energy of the same bullet in Galileo's and Einstein's special relativity are derived. The special relativity result is extended to the case of a photon.

Particle density and non-local kinetic energy density functional for two-dimensional harmonically confined Fermi vapors

, 2001
We evaluate analytically some ground state properties of two-dimensional harmonically confined Fermi vapors with isotropy and for an arbitrary number of closed shells.

Facile Synthesis of CuxS Electrocatalysts for CO2 Conversion into Formate and Study of Relations Between Cu and S with the Selectivity

Advanced Functional Materials, EarlyView.
Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

All coordinates transformations that separate the center of mass kinetic energy, their group structure and geometry

, 2009
The most general coordinates transformations that allow for the exact separation of the kinetic energy operator of a quantum many-body system into total center of mass kinetic energy and internal kinetic energy are found and discussed.

On conditions for contrail formation from aircraft exhausts

Meteorologische Zeitschrift, 1996
The formation of contrails (condensation trails) from aircraft exhaust has been investigated since 1919. Related studies are reviewed. The thermodynamical foundation of the Appleman threshold criterion for contrail formation has been first described by ...

The Kinetic Theory and Radiant Energy [PDF]

Nature, 1898
IN the course of the discussion which took place in your columns during the winter of 1894–5 on tne kinetic theory of gases, emphasis was rightly laid on the difficulty of reconciling the law of partition of energy among the different degrees of freedom of molecules of gases with the large number of such degrees of freedom indicated by their spectra ...

In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.

Comparative analysis of kinetic energy budget of Typhoons Yagi and Rumbia

Tropical Cyclone Research and Review
In this paper, the ERA-Interim reanalysis data at six-hourly intervals (with a horizontal resolution of 0.25° × 0.25°) and typhoon best track datasets are used to conduct a comparative kinetic energy budget analysis of Typhoon Yagi and Rumbia during ...
