Carbon Energy, EarlyView.This review reveals how electronic configuration engineering governs the entire electrocatalytic nitrogen cycle, providing structure‐informed insights into reaction selectivity, catalytic durability, and sustainable nitrogen utilization across energy and environmental systems. ABSTRACT The global nitrogen cycle is essential to food production, chemical

Carbon Energy, EarlyView.Bamboo diaphragm−derived carbon is used as a support to prepare Ru–Pd–Pt/C catalysts through a stepwise reduction strategy. The Ru–Pd interface promotes formic acid activation and induces Pt deposition. The metallic interface of Ru–Pd–Pt/C enables H* generation, transfer, and recombination, thereby improving Pt utilization, acidic HER activity, and PEM

Stabilizing a metalloid {Zn12} unit within a polymetallide environment in [K2Zn20Bi16]6−
Nature Communications, 2020 Low-valent zinc clusters, though exceedingly rare, are appealing synthetic targets because there is evidence that they may show unconventional chemical and physical behavior.

Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes
Chemistry – A European Journal, EarlyView.A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

A Cyclic {NiII8DyIII4} Cluster Where the DyIII Moments Are Organized by the Transition Metal Spins
Chemistry – A European Journal, EarlyView.The synthesis, structural characterisation, and magnetic properties of a cyclic Ni8Dy4 coordination cluster are reported. Ab initio CASSCF and DFT calculations help rationalize the shape of the microSQUID hysteresis and the competing magnetic interactions within the compound. ABSTRACT A series of [Ni8Ln4(CO3)4(L)8(NO3)2(H2O)8 (MeOH)4](NO3)2 (Ln = Dy (1)

Proton NMR Study of Cr−Co Heterometallic Wheel Complexes
, 2016 1H NMR spectra of the paramagnetic heterometallic complexes of general formula [cation][Cr7CoF8(O2CtBu)16] have been recorded. The NMR spectra have allowed the investigation of the structure of these complexes in solution. These experiments show that the

Scaling Up Molecular Electron Spin Qubits Around a Core‐Shell Quantum Dot
Chemistry – A European Journal, EarlyView.Making assemblies of molecular nanomagnet (MNM) qubits is an essential step toward scalable quantum devices. Here, SH‐functionalized {Cr7Ni} antiferromagnetic rings with ability as MNM qubits were successfully grafted to the surface of fluorescent CdSe/ZnS quantum dots (QD).

Host–guest capability of a three-dimensional heterometallic macrocycle
, 2018 Three-dimensional heterometallic macrocycles with half-sandwich Rh corners were studied for their ability to trap planar and non-planar guests. Furthermore, these heterometallic macrocycles can be destroyed in the presence of a soft base to form ...

Chemistry – A European Journal, EarlyView.Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(
