Gas heating from spinning and non-spinning evaporating primordial black holes

Physics Letters B, 2021
Primordial black holes (PBHs) from the early Universe constitute a viable dark matter (DM) candidate and can span many orders of magnitude in mass. Light PBHs with masses around 1015 g contribute to DM and will efficiently evaporate through Hawking ...

From Waste to Watts: Cigarette Filter Waste to Carbon Nanomaterial‐Based Supercapacitors for Sustainable Energy Storage Applications

Battery Energy, EarlyView.
We present an economically viable approach for synthesizing carbon nanomaterials derived from discarded cigarette filters, an abundant environmental pollutant. The resulting material exhibits desirable characteristics, including a well‐defined stacking structure, high porosity, and a substantial specific surface area, making it suitable as an active ...

Global Disk Oscillation Modes in Cataclysmic Variables and Other Newtonian Accretors

, 2007
Diskoseismology, the theoretical study of small adiabatic hydrodynamical global perturbations of geometrically thin, optically thick accretion disks around black holes (and other compact objects), is a potentially powerful probe of the gravitational ...

SEC‐SAXS/MC Ensemble Structural Studies of the Microtubule Binding Protein Cdt1 Show Monomeric, Folded‐Over Conformations

Cytoskeleton, EarlyView.
ABSTRACT Cdt1 is a mixed folded protein critical for DNA replication licensing and it also has a “moonlighting” role at the kinetochore via direct binding to microtubules and the Ndc80 complex. However, it is unknown how the structure and conformations of Cdt1 could allow it to participate in these multiple, unique sets of protein complexes.

Multiwavelength Constraints on the Local Black Hole Occupation Fraction

The Astrophysical Journal
The fraction of dwarf galaxies hosting central, intermediate-mass black holes (IMBHs) at low redshifts is an important observational probe of black hole seeding at high redshift.

35Cl NMR of Metal‐Organic Frameworks: What Can We Learn?

Chemistry–Methods, EarlyView.
35Cl solid‐state NMR of MOFs offers insights into bonding mode and character, hydrogen bonding, phase transitions, and reaction products, even near paramagnetic centers. 35Cl NMR parameters reflect Cl coordination and local geometry. DFT methods accurately predict 35Cl NMR parameters. This 35Cl NMR/DFT approach is applicable to other MOFs and materials.

Suppression of auxin signalling promotes rice susceptibility to Rice black streaked dwarf virus infection

Molecular plant pathology, 2019
Summary Auxin plays a fundamental role in plant growth and development, and also influences plant defence against various pathogens. Previous studies have examined the different roles of the auxin pathway during infection by biotrophic bacteria and ...

Hubble Space Telescope Imaging of the Active Dwarf Galaxy RGG 118

, 2017
RGG 118 (SDSS 1523+1145) is a nearby ($z=0.0243$), dwarf disk galaxy ($M_{\ast}\approx2\times10^{9} M_{\odot}$) found to host an active $\sim50,000$ solar mass black hole at its core (Baldassare et al. 2015). RGG 118 is one of a growing collective sample
