Diagnosing the time-dependence of active region core heating from the emission measure: I. Low-frequency nanoflares [PDF]

, 2012
Observational measurements of active region emission measures contain clues to the time-dependence of the underlying heating mechanism. A strongly non-linear scaling of the emission measure with temperature indicates a large amount of hot plasma relative

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Modeling the X-rays Resulting from High Velocity Clouds [PDF]

, 2012
With the goal of understanding why X-rays have been reported near some high velocity clouds, we perform detailed 3 dimensional hydrodynamic and magnetohydrodynamic simulations of clouds interacting with environmental gas like that in the Galaxy's thick ...

Why Does Atmospheric Radiative Heating Weaken Midlatitude Cyclones?

Geophysical Research Letters
Recent work has indicated that atmospheric radiative heating reduces the kinetic energy of large‐scale eddies in the midlatitudes. However, a physical mechanism that connects radiation to the midlatitude eddy kinetic energy is still uncertain.

Interior dynamics of envelopes around disk-embedded planets

Astronomy & Astrophysics
In the core accretion scenario, forming planets start to acquire gaseous envelopes while accreting solids. Conventional 1D models assume envelopes to be static and isolated.

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Low-energy-consumption temperature swing system for CO2 capture by combining passive radiative cooling and solar heating

Green Energy & Environment
Temperature-swing adsorption (TSA) is an effective technique for CO2 capture, but the temperature swing procedure is energy-intensive. Herein, we report a low-energy-consumption system by combining passive radiative cooling and solar heating for the ...

Thermal modeling, heat mitigation, and radiative cooling for double-clad fiber amplifiers

Journal of the Optical Society of America B, 2018
We report a detailed formalism aimed at the thermal modeling and heat mitigation in high-power double-clad fiber amplifiers. Closed form analytical formulas are developed that take into account the spatial profile of the amplified signal and pump in the double-clad geometry, the presence of the amplified spontaneous emission, and the possibility of ...
