A Possible Formation Scenario of the Gaia ID 3425577610762832384: Inner Binary Merger inside a Triple Common Envelope

open access: yesThe Astrophysical Journal Letters
Recently, an identified noninteracting black hole (BH) binary, Gaia ID 3425577610762832384 (hereafter G3425), contains a BH (∼3.6 M _⊙ ) falling within the mass gap and has a nearly circular orbit, challenging the classical binary evolution and supernova

Numerical investigation of an orbital forming process to join dissimilar materials with local material accumulation

open access: yesJournal of Advanced Joining Processes
Increasing demands for lightweight design and functional integration in modern production technology require innovative manufacturing processes. Multi-material systems offer a high potential to face these challenges by reducing weight while maintaining ...

Transient Processes in a Binary System with a White Dwarf

open access: yesActa Polytechnica CTU Proceedings, 2015
Using the results of 3D gas dynamic numerical simulations we propose a mechanism that can explain the quiescent multihumped shape of light curves of WZ Sge short-period cataclysmic variable stars.

Lattice-form-dependent orbital shape and charge disproportionation in charge- and orbital-ordered manganites [PDF]

open access: yesPhysical Review B, 2009
The orbital shapes and charge disproportionations at nominal Mn$^{3+}$ and Mn$^{4+}$ sites for the charge- and orbital-ordered phases have been studied on half-doped manganites Pr(Sr$_{0.1}$Ca$_{0.9}$)$_2$Mn$_2$O$_7$ and Eu$_{0.5}$Ca$_{1.5}$MnO$_4$ with double-layer and single-layer Mn-O networks, respectively, by means of x-ray structural analyses, in

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

The Material Flow Analysis in the Modified Orbital Forging Technology

open access: yes, 2010
The main aim of this work is the computer aided design of the new orbital forging process. The finite element model was developed and used in research on possibility of modification of the classical orbital forging technology based on the Marciniak press

Coulomb, orbital, and spin interactions in 1D exactly solved model

open access: yes, 2000
Large number of actual heavy-fermionic alloys display non-Fermi liquid behavior [l]. Recent achievements in the description of 1D models give the possibility to indicate some mechanisms of forming special properties of fermionic systems. Usual parameters

EDTA as a corrosion inhibitor for Al in 0.5 M HCl: adsorption, thermodynamic and theoretical study

open access: yesJournal of Electrochemical Science and Engineering, 2016
In this study; EDTA is used in very small amount (10-10 M) as an inhibitor for the Al corrosion in 0.5 M HCl. Thermodynamic and adsorption parameters are calculated.

Planets in orbit around β Pictoris formed the orbital architecture of planetesimal belts? [PDF]

open access: yesEarth, Planets and Space, 2010
We report near-infrared imaging observations of the β Pic dust disk, from which we infer the orbital architecture of planetesimal belts that remain near mean motion resonances (MMRs) with a planet at 62 AU. Our results reveal that one of the previously identified planetesimal belts lies in the 2/3 MMR with the planet, similar to the resonant relation ...

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and
