Anhydrous Methane Sulfonates of Group 13 Metals: Synthesis and Characterization of Ga(CH3SO3)3, In(CH3SO3)3, and Tl(CH3SO3)3

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 16, November 14, 2025.
In the crystal structures of the methanesulfonates M[CH3SO3]3 (M = Ga, In, Tl), the metal ions are linked into chains or layers by bidentate bridging anions.The anhydrous group 13 methanesulfonates M[CH3SO3]3 (M = Ga, In, Tl) are obtained from reactions of Ga2[SO4]3, In2O3, and Tl[NO3], respectively, with CH3SO3H in sealed glass ampoules at a ...

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

Advanced 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

The ionisation parameter of star-forming galaxies evolves with the specific star formation rate

, 2018
We investigate the evolution of the ionisation parameter of star-forming galaxies using a high-redshift ($z\sim 1.5$) sample from the FMOS-COSMOS survey and matched low-redshift samples from the Sloan Digital Sky Survey.

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

Chemistry – 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

Default Prediction in the Finance Industry Based on Ensemble Learning: Combining Machine Learning and Deep Learning

Business Systems Research
Financial institutions face significant challenges in predicting loan defaults, which directly impact the non-performing loan (NPL) rate. Incorrect predictions can lead to misinformed decisions and substantial financial losses.

Rest-Frame Optical Spectra of Three Strongly Lensed Galaxies at z~2

, 2009
We present Keck II NIRSPEC rest-frame optical spectra for three recently discovered lensed galaxies: the Cosmic Horseshoe (z = 2.38), the Clone (z = 2.00), and SDSS J090122.37+181432.3 (z = 2.26).
