Luminescence and Single‐Molecule Magnet Properties in Ideal Symmetry Compounds: Example of a Near‐Planar Tricoordinate Ytterbium(III) Amide Open
We are reporting on the use of a low‐coordinate Yb III amide with near‐ideal planar trigonal [Yb{N(SiMe 3 ) 2 } 3 ] ( 1 ) and on a bipyramidal trigonal derivative [Yb{N(SiMe 2 H) 2 } 3 ⋅ (thf) 2 ] ( 2 ) that constitute quintessential cases…

Direct Conversion of Alginate Oligo‐ and Polysaccharides into Biodegradable and Non‐Ecotoxic Anionic Furanic Surfactants—An Experimental and Mechanistic Study Open
A series of novel anionic furanic surfactants characterized by the presence of a couple of lipophilic chains acetal‐linked to a sodium 2‐furoate head group, are prepared by the conversion of oligo‐alginates or alginate to butyl 5‐(dibutoxy…

Theoretical Analysis of the Mackay Icosahedral Cluster Pd<sub>55</sub>(P<i>i</i>Pr<sub>3</sub>)<sub>12</sub>(μ<sub>3</sub>‐CO)<sub>20</sub>: An Open‐Shell 20‐Electron Superatom Open
The electronic structure of the spherical Mackay icosahedral nanosized cluster Pd 55 (P i Pr 3 ) 12 (μ 3 ‐CO) 20 is analyzed by using DFT calculations. Results reveal that it can be considered as a regular superatom with a “magic” electron…

6-Deoxy-6-fluoro galactofuranosides: regioselective glycosylation, unexpected reactivity, and anti-leishmanial activity Open
Standard glycosylation of unprotected 6-fluorogalactofuranoside turned to three competitive reactions and afforded difuranosides able to impact growth of Leishmania tarentolae.

Tetrathiafulvalene-Based Helicene Ligand in the Design of a Dysprosium Field-Induced Single-Molecule Magnet Open
The design of a coordination complex that involves a ligand combining both a tetrathiafulvalene core and a helicene fragment was achieved thanks to the reaction between the new 2-{1-[2-methyl[6]helicene]-4,5-[4,5-bis(propylthio)tetrathiafu…

Focusing of Rayleigh waves with gradient-index phononic crystals Open
We report on the subwavelength focusing of Rayleigh waves using gradient-index (GRIN) phononic crystals (PCs) made of air holes scatters in a thick silicon substrate. The subwavelength focusing is demonstrated both in the inner and in the …
