Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

open access: yesAdvanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

An overview of atmospheric deposition chemistry over the Alps: present status and long-term trends [PDF]

open access: yes, 2006
Several research programs monitoring atmospheric deposition have been launched in the Alpine countries in the last few decades. This paper uses data from previous and ongoing projects to: (i) investigate geographical variability in wet deposition ...

Spatial distribution of marine atmospheric isoprene in the Southern Hemisphere: Role of atmospheric removal capacity

open access: yes, 2023
Isoprene is important to the formation of secondary organic aerosols and can change the atmospheric oxidation capacity in the remote marine environment. However, the influencing factors of marine atmospheric isoprene are still unclear.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

A One-dimensional Microphysical Model of the Venus Cloud System between 40 and 80 km Including Photochemistry and Radiative-dynamic Feedback

open access: yesThe Planetary Science Journal
We present results from 1D simulations using PlanetCARMA for Venus in which, for the first time, a sophisticated 1D cloud microphysics model has simultaneously incorporated simplified diurnally varying photochemistry, parameterized diurnally varying ...

Internal Atmospheric Dynamics and Tropical Indo-Pacific Climate Variability

open access: yes, 2005
One possible explanation for tropical sea surface temperature (SST) interannual variability is that it can be accurately described by a linear autoregressive model with damped coupled feedbacks and stochastic forcing.

What can 14 CO measurements tell us about OH? [PDF]

open access: yes, 2008
The possible use of 14CO measurements to constrain hydroxyl radical (OH) concentrations in the atmosphere is investigated. 14CO is mainly produced in the upper atmosphere from cosmic radiation.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Variability of the global atmospheric circulation during the past 100 years

open access: yesMeteorologische Zeitschrift, 2009
In order to better understand climate variability, it is essential to address the underlying variability in the atmospheric circulation. How does the circulation interact with the ocean or land surface? How is it affected by external forcings?
