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 ...

Copper in cancer: friend or foe? Metabolism, dysregulation, and therapeutic opportunities
Cancer Communications, EarlyView.Abstract Copper, one of the essential nutrients for the human body, acts as an electron relay in multiple pathways due to its redox properties. Both deficiencies and excesses of copper lead to cellular fragility. Therefore, it can manifest pro‐ and anti‐cancer properties in tumors. Therefore, it is crucial to clarify the copper activity within the cell.

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.

Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Photometric White Dwarf Rotation
The Astrophysical JournalWe present a census of photometrically detected rotation periods for white dwarf (WD) stars. We analyzed the light curves of 9285 WD stars observed by the Transiting Exoplanet Survey Satellite up to Sector 69.

Astrophysics of white dwarf binaries [PDF]
AIP Conference Proceedings, 2006 White dwarf binaries are the most common compact binaries in the Universe and are especially important for low-frequency gravitational wave detectors such as LISA. There are a number of open questions about binary evolution and the Galactic population of white dwarf binaries that can be solved using gravitational wave data and at the same time, our ...

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction
Contributions to Plasma Physics, EarlyView.ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

The Solar Neighborhood. XXI. Parallax Results from the CTIOPI 0.9m Program: 20 New Members of the 25 Parsec White Dwarf Sample [PDF]
, 2009 We present accurate trigonometric parallaxes for 20 new members of the 25 pc white dwarf sample as part of the DENSE project (Discovery and Evalution of Nearby Stellar Embers, http://www.DenseProject.com). Previously, there were a total of 112 white dwarf systems with trigonometric parallaxes placing them within 25 pc and of these, 99 have ...

White-dwarf asteroseismology: An update [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractThe vast majority of stars that populate the Universe will end their evolution as white-dwarf stars. Applications of white dwarfs include cosmochronology, evolution of planetary systems, and also as laboratories to study non-standard physics and crystallization. In addition to the knowledge of their surface properties from spectroscopy combined

Asteroseismology of the ZZ Ceti and DAZ GD133
EPJ Web of Conferences, 2017 GD 133 is a DAZ white dwarf with an atmosphere polluted by heavy elements accreted from a debris disk, which is formed by the disruption of rocky planetesimals with orbits bringing them at the white dwarf tidal radius.
