Self‐Assembled Luminescent Au(I)–Adamantylamine Coordination Polymer Needles With Thermoresponsive Optical Properties

open access: yesChemistry – A European Journal, EarlyView.
A self‐assembled hydrophobic and red phosphorescent Au(I) coordination polymer (CP) was synthesized under mild conditions. Single‐crystal X‐ray diffraction (XRD) demonstrated linear Au(I) chains stabilized by aurophilic and hydrogen bonding interactions.

Quadratic electronic response of a two-dimensional electron gas

open access: yes, 1998
The electronic response of a two-dimensional (2D) electron system represents a key quantity in discussing one-electron properties of electrons in semiconductor heterojunctions, on the surface of liquid helium and in copper-oxide planes of high ...

Astragalus ecomorphology in Quaternary elephantids

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Ab initio calculations of the dynamical response of copper

open access: yes, 1999
The role of localized $d$-bands in the dynamical response of Cu is investigated, on the basis of {\em ab initio} pseudopotential calculations. The density-response function is evaluated in both the random-phase approximation (RPA) and a time-dependent ...

Are the HI deficient galaxies on the outskirts of Virgo recent arrivals? [PDF]

open access: yes, 2002
The presence on the Virgo cluster outskirts of spiral galaxies with gas deficiencies as strong as those of the inner galaxies stripped by the intracluster medium has led us to explore the possibility that some of these peripheral objects are not ...

Persistent Alarms Confronting New Priorities: Protestants in Africa in Italian and French Catholic Magazines (1945–1962)

open access: yesJournal of Religious History, EarlyView.
Anti‐Protestantism was one of the reasons for the revival of missions during the interwar period. By the 1960s, however, Protestants were less and less often mentioned as a threat to missionary efforts, and the decline in inter‐confessional tensions was increasingly considered a relic of the past.

Memoria dell’effimero. Verso un archivio digitale del teatro e della scena barocca italiana

open access: yesDiségno, 2022
Sul finire del Cinquecento, Venezia apre i primi teatri pubblici a pagamento, ma ciò sembra presagire una storia fallimentare, a giudicare dalle entrate delle famiglie Michiel e Tron, perché il successo di un seguito interrotto per circa cinquantasette ...
