Cu─X Bonds Regulated Conduction and Polarization Loss in Conductive Metal‐Organic Framework Under Electromagnetic Field

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly

Constraints on CP violation in the Higgs sector from the $\rho$ parameter

open access: yes, 1993
We discuss the relation between the CP symmetry and the custodial $SU(2)$ symmetry in the Higgs sector. In particular, we show that CP violation in the Higgs-gauge sector is allowed only if the custodial $SU(2)$ symmetry is broken. We exploit these facts

Pd[B(S2O7)2]2 and Pd[B(SO4) (S2O7)]2: Two Borosulfates with Pd2+ in Octahedral and One with Pd2+ in Square Planar Oxygen Coordination

open access: yesChemistry – A European Journal, Volume 31, Issue 42, July 25, 2025.
Two polymorphs of Pd[B(S2O7)2]2 have been obtained as blue crystals, respectively. The [B(S2O7)2]− –anions coordinate the central Pd2+ cations via oxygen atoms in octahedral fashion. With Pd2+ as d8 high‐spin cations the bulk samples are paramagnetic. Furthermore, Pd[B(SO4)(S2O7)] has been obtained as side product in form of red crystals. The structure

Ultraviolet spectra of extreme nearby star-forming regions --- approaching a local reference sample for JWST

open access: yes, 2017
Nearby dwarf galaxies provide a unique laboratory in which to test stellar population models below $Z_\odot/2$. Such tests are particularly important for interpreting the surprising high-ionization UV line emission detected at $z>6$ in recent years.
