Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...

Computation of gravitational waves from inspiraling binary neutron stars in quasiequilibrium circular orbits : Formulation and calibration [PDF]

open access: yes, 2001
Gravitational waves from binary neutron stars in quasiequilibrium circular orbits are computed using an approximate method which we propose in this paper. In the first step of this method, we prepare general relativistic irrotational binary neutron stars

Complex population genetic structure of the bark beetle predator Thanasimus formicarius (L.) (Coleoptera: Cleridae) across its European range

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 3, Page 437-451, August 2025.
Abstract Thanasimus formicarius (L.) (Coleoptera: Cleridae) is an important bark beetle predator and can reduce bark beetle population densities of some of the most severe forest pests in Europe. We analysed the population genetics and phylogeography of T.

High‐pressure crystal structure of n‐hexylamine

open access: yesActa Crystallographica Section C, Volume 81, Issue 6, Page 346-350, June 2025.
The high‐pressure crystal structure of n‐hexylamine remains isostructural with its low‐temperature phase. The compressibility of the N—H…N hydrogen bonds has been analyzed in relation to the shortest C—H…N and H…H intermolecular distances.A primary amine, n‐hexylamine (HA, C6H15N), has been studied at high pressure by single‐crystal X‐ray diffraction ...

Softly Broken Supersymmetric Desert from Orbifold Compactification

open access: yes, 2002
A new viewpoint for the gauge hierarchy problem is proposed: compactification at a large scale, 1/R, leads to a low energy effective theory with supersymmetry softly broken at a much lower scale, \alpha/R.
