Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Experimental Observation of a Calcium Silicon Double Carbonate

Angewandte Chemie, EarlyView.
High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Energetics of Electron Pairs in Electrophilic Aromatic Substitutions

Molecules, 2021
The interacting quantum atoms approach (IQA) as applied to the electron-pair exhaustive partition of real space induced by the electron localization function (ELF) is used to examine candidate energetic descriptors to rationalize substituent effects in ...

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

Advanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Synthesis, structural and spectroscopic characterization of thallium(I) acesulfamate [PDF]

, 2015
The new acesulfamate salt, TlC4H4NO4S, was prepared by reaction of acesulfamic acid and thallium(I) carbonate in aqueous solution. Its crystal and molecular structure was determined by single crystal X-ray diffraction methods. The substance crystallizes
