Abstract

Nicolas Wagner : Morelly : present state of research. Although little known and superficially read, Morelly has nevertheless been enlisted by critics among the Utopians and precursors of socialism. It is neces¬ sary above all to return to the author himself, as far as possible, and to the manuscript sources, which are listed here for the first time. Their interest is briefly explained (personal documents, Ferme Générale, editors, protectors, police). There is also an important corpus of 18th-century reviews of Morelly's works, which enables us to place him in his political and ideological context (1743-1754). Thus we can evaluate more concretely the significance and literary value of his work, and in particular of the Code.

Periodic Charging of Individual Molecules Coupled to the Motion of an Atomic Force Microscopy Tip

“…To test this hypothesis, we extracted Δ f dip ( V ) by subtracting the overall parabolic behavior from Δ f ( V )-spectra measured at a set of slightly elevated temperatures between 5.2 and 13.9 K. Two of these Δ f dip ( V )-curves are shown in Figure b for the temperatures of 5.2 and 9.5 K, respectively. The increase in width at elevated temperatures is directly apparent from the graphs, confirming our hypothesis of the thermal broadening being dominant . To analyze this quantitatively, we fitted many analogous Δ f dip ( V )-curves for a set of three different amplitudes and five different temperatures to Gaussian functions.…”

“…These values have been obtained under the assumption that the lifetime broadening is negligible against temperature broadening and for a lever arm of α = 1/62 and a tip–sample distance of 6 Å. The lever arm α equals the ratio of the capacitive coupling of the molecule to the tip over the capacitive coupling of the molecule to the entire environment (to the sample, ground, and the tip). ,, Both above values are reasonable for the given geometry . More details of the fit are provided as Supporting Information.…”

Construction and physical properties of low-dimensional structures for nanoscale electronic devices

“…2,63,67,71,72,79,[183][184][185][186][187][188][189] To this end, great efforts have been devoted to probing electronic transport properties through a single-molecule junction, 63,67,73,74,184,[186][187][188][190][191][192][193][194][195][196][197][198][199][200][201][202] in which the electron transport can be controlled by field regulation of single-molecule conductivity using a charged surface atom, 194 by tuning the molecular conformation, 184 by molecular interactions, 197 using local electric fields, 203 by hydrogenation of molecules, 180,204 or by tuning molecular adsorption sites. 205 Although the spin states of molecules can be controlled mechanically 206 or electrically, 207 or by applying magnetic fields, 61,208,209 revers...…”

“…205 Although the spin states of molecules can be controlled mechanically 206 or electrically, 207 or by applying magnetic fields, 61,208,209 reversible control of a single spin of the molecule is still quite challenging. 63,66,67,187,188,201 The spin states of molecules can manifest themselves as spin-related transport phenomena, such as negative differential resistance 209 or the Kondo effect, 60,180,205 in which the spin of the molecules is coupled to the conduction channels and a conduction anomaly emerges at the Fermi level. 68,190,210,211 Many attempts have been applied to tune the Kondo effect of molecule systems, including conformation variation, 212 alternation of adsorption sites, 213 quantum size effects, 214 ligand attachment, 215 molecular assembly, 216 and atomic doping; 217 however, none of them are reversible or can tune the Kondo effect at the single-molecule level.…”
