Queen Anne of Romania and the “Danish escape route” [PDF]

Dialogica: Revistă de Studii Culturale și Literatură
A series of previously unpublished documents from the Rațiu Archive in London show how the Romanian Royal Family, in particular Queen Ana, together with the World Union of Free Romanians, led by Ion Rațiu, intervened to save one of the main routes used ...

Upper atmospheres and ionospheres of planets and satellites

, 2017
The upper atmospheres of the planets and their satellites are more directly exposed to sunlight and solar wind particles than the surface or the deeper atmospheric layers.

Kinetic effects on ion escape at Mars and Venus: Hybrid modeling studies

Earth, Planets and Space, 2012
Kinetic effects are anticipated to play a role at Mars and Venus when the escape of planetary ions is considered because of the large ion gyroradius compared with the size of the planets.

Escape of heated ions upstream of quasi‐parallel shocks

Geophysical Research Letters, 1982
We investigate the free escape of ions from the post shock plasma into the region upstream of a fast collisionless shock. We find that the accessibility of downstream ions to the upstream region depends strongly on the upstream magnetic field shock normal angle as well as the upstream plasma parameters.

Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

Advanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

Venusian hydrology: Steady state reconsidered [PDF]

In 1987, Grinspoon proposed that the data on hydrogen abundance, isotopic composition, and escape rate were consistent with the hypothesis that water on Venus might be in steady state rather than monotonic decline since the dawn of time.

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

Advanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

Escape fraction of ionizing photons from high-redshift galaxies in cosmological SPH simulations

, 2010
Combing the three-dimensional radiative transfer (RT) calculation and cosmological SPH simulations, we study the escape fraction of ionizing photons (f_esc) of high-redshift galaxies at z=3-6.

Biomimetic Copper‐Doped Nano‐Aluminum Adjuvant Potentiates Therapy in Chemoresistant Acute Myeloid Leukemia

Advanced Healthcare Materials, EarlyView.
We developed a novel copper‐doped aluminum nano‐adjuvant (CuNA) to overcome cytarabine resistance in acute myeloid leukemia (AML). CuNA effectively sensitizes drug‐resistant AML cells to cytarabine by inducing mitochondrial dysfunction and inhibiting HMGCR/GPX4 to amplify ferroptosis.

Enhanced Acceleration and Escape of Hydrogen Pickup Ions Upstream from Mars by Interplanetary Shocks

The Astrophysical Journal
The pickup process of newly ionized hydrogen (H) from the Martian extended exosphere represents an important H ^+ escape channel on Mars. It is generally believed that interplanetary (IP) shocks can accelerate the pickup ions and, in turn, affect the ...
