Studying the Electron Energy Distribution Function (EEDF) and Electron Transport Coefficients in SF6 – He Gas Mixtures by Solving the Boltzmann Equation

open access: yesمجلة بغداد للعلوم, 2017
The Boltzmann equation has been solved using (EEDF) package for a pure sulfur hexafluoride (SF6) gas and its mixtures with buffer Helium (He) gas to study the electron energy distribution function EEDF and then the corresponding transport coefficients ...

Thermal accommodation in nanoporous silica for vacuum insulation panels

open access: yesInternational Journal of Thermofluids, 2020
The thermal accommodation coefficient is a measure for the quality of thermal energy exchange between gas molecules and a solid surface. It is an important parameter to describe heat flow in rarefied gases, for example, in aerospace or vacuum technology.

UTMD Suppresses CSF‐1 to Drive Macrophage‐Mediated Ferroptosis in Papillary Thyroid Carcinoma

open access: yesCancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT The tumor microenvironment (TME) of Papillary Thyroid Carcinoma (PTC), particularly the role of tumor‐associated macrophages (TAMs), contributes to therapeutic resistance. This study investigated whether ultrasound‐targeted microbubble destruction (UTMD), a non‐invasive physical modality, could reprogram the TME through modulation of TAMs and ...

Pressure dependence in the multiphoton dissociation of sulfur-32 hexafluoride

open access: yes
The multiphoton dissocn. of 32SF6 was studied in the presence of several inert gases. The reciprocal dissocn. yields increase with increasing total pressure in a nonlinear way for the conditions applied.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

open access: yesPortal Hypertension &Cirrhosis, Volume 5, Issue 3, Page 260-268, September 2026.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Interferometric Measurements of Isotherms of Sulfur Hexafluoride in the Critical Region

open access: yes, 1972
Isotherms of sulfur hexafluoride in the critical region have been determined by interferometric measurements. A thin sample of pure fluid, compressed under its own weight, is placed in one arm of a Mach–Zehnder interferometer. The resulting interference

Grazing Enhances System Carbon Balance via the Soil‐Plant‐Livestock Carbon Pump Regulation Despite Suppressing Specific Carbon Cycling Pathways

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Grazing is among the most direct and effective strategies for anthropogenic regulation of carbon cycling in global grasslands. Through a 24‐year grazing experiment, we propose a conceptual framework of the “Soil‐Plant‐Livestock Carbon Pump” to elucidate the mechanisms underlying grazing effects on carbon cycling within plant, soil, livestock ...
