Metastable Nanosized Diamond Formation from Fluid Systems [PDF]
, 2010 The model of nanosized diamond particles formation at metastable P-T parameters from fluid is presented. It explains the specific of CVD diamond synthesis gases mixtures and hydrothermal growth of diamond at low P-T parameters as well as it explains the ...

A photon transport problem with a time-dependent point source [PDF]
, 2009 We consider a time-dependent problem of photon transport in an interstellar cloud with a point photon source modeled by a Dirac δ functional. The existence of a unique distributional solution to this problem is established by using the theory of ...

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations [PDF]
, 2001 We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Investigating the IBEX Ribbon Structure a Solar Cycle Apart
The Astrophysical Journal, 2023 A “Ribbon” of enhanced energetic neutral atom (ENA) emissions was discovered by the Interstellar Boundary Explorer in 2009, redefining our understanding of the heliosphere boundaries and the physical processes occurring at the interstellar interface. The

Properties of Star Formation of the Large Magellanic Cloud As Probed by Young Stellar Objects
The Astrophysical Journal, 2023 We perform a systematic study of the evolutionary stages and stellar masses of young stellar objects (YSOs) in the Large Magellanic Cloud (LMC) to investigate the properties of star formation in the galaxy. There are 4825 sources in our YSO sample, which

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

The formation of molecular hydrogen in the interstellar medium [PDF]
, 2010 H2 is the most abundant molecule in the interstellar medium and forms on the surface of interstellar dust grains. Laboratory studies have been conducted of HD formation on a dust grain analogue, which is a highly-oriented pyrolytic graphite surface ...

Optical Radiation Pressure: Resonant Mechanical Excitation of Thin Films
Annalen der Physik, Volume 538, Issue 10, October 2026.The modulation of a laser beam generates a modulated radiation pressure force acting on a thin film. A resonant response is observed, leading to a net average thinning of the film. ABSTRACT Optical radiation pressure was directly observed for the first time more than a century ago.
