The origin of the elements and other implications of gravitational wave detection for nuclear physics

4 open, 2020
The neutron-star collision revealed by the event GW170817 gave us a first glimpse of a possible birthplace of most of our heavy elements. The multi-messenger nature of this historical event combined gravitational waves, a gamma-ray burst and optical ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Gravitational lensing reveals cool gas within 10-20 kpc around a quiescent galaxy

Communications Physics
While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic medium (CGM) compared to star-forming galaxies, they have significantly less interstellar gas.

Random walk of magnetic field lines for different values of the energy-range spectral index

, 2007
An analytical nonlinear description of field-line wandering in partially statistically magnetic systems was proposed recently [A. Shalchi, I. Kourakis, Astronomy and Astrophysics, 470, 405 (2007)]. In this article we investigate the influence of the wave-

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

Advanced Materials, EarlyView.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

Physics at the University of Lviv since the 17th century until the second world war: Addenda to the bibliography [PDF]

Studia Historiae Scientiarum, 2016
Previously, an attempt was made to compile in a series of papers a complete bibliography of works related to physics at the University of Lviv. The period since the foundation of the University in 1661 until the division of the Chair of Physics in 1872 ...

Stellar Radio Astronomy. Probing Stellar Atmospheres from Protostars to Giants

, 2002
Radio astronomy has provided evidence for the presence of ionized atmospheres around almost all classes of non-degenerate stars. Magnetically confined coronae dominate in the cool half of the Hertzsprung-Russell diagram.

Weakly‐Coordinating Non‐Fluorinated Diluents for Local High‐Concentration Electrolytes in Advanced Lithium Metal Batteries

Advanced Materials, EarlyView.
This perspective critically evaluates non‐fluorinated diluents in local high‐concentration electrolytes, categorizing their solvation behavior, interfacial mechanisms, and sustainability potential to guide future electrolyte design for lithium metal batteries.

ENSINO DE ASTRONOMIA NO BRASIL - 1850 A 1951 - UM OLHAR PELO COLÉGIO PEDRO II

Ensaio Pesquisa em Educação em Ciências, 2010
The teaching of Astronomy in Brazil is analyzed in the 18 programs of the Pedro II School, relative to the 1841 to 1951 reforms, based on the understanding that the curriculum is the result of a process made up of conflicts and disputes between different

Probing Binary Architectures of Lithium-rich Giants in GALAH with COSMIC and Stellar Models

The Astrophysical Journal
Surface lithium is depleted when a star goes through the first dredge-up phase, yet 1% of red giants are found to be Li rich. The formation mechanism for these remains uncertain. We combine observational constraints from Galactic Archaeology with HERMES (
