Polycrystalline CuMo1?xWxO4 solid solutions were studied by resonant X-ray emission spectroscopy (RXES) at the W L3-edge to follow a variation of tungsten local atomic and electronic structures across thermochromic phase transition as function sample composition temperature. The experimental results interpreted using ab initio calculations. crystal-field splitting parameter ? for 5d(W)-states w...

There have been recently several works studying the regularized stochastic heat equation (SHE) and Kardar–Parisi–Zhang (KPZ) in dimension d≥3 as smoothing parameter is switched off, but most of results did not hold full temperature regions where they should. Inspired by martingale techniques coming from directed polymers literature, we first extend law large numbers for SHE obtained Mukherjee e...

Fe3O4 nanoparticles decorated on cellulose aerogel (CA) from banana stems (Fe3O4@CA) were synthesized for application in the Fenton degradation of p-nitrophenol (PNP). Cellulose extracted raw was with kymene as a crosslinking agent and freeze-dried method. The Fe3O4@CA samples characterized by X-ray diffraction (XRD), Energy-dispersive spectroscopy (EDS), Scanning Electron Microscope (SEM), Tra...

The central pattern generators (CPGs) of invertebrates have features that make them uniquely profitable for examining the cellular mechanisms underlying rhythm generation and pattern formation. Early ideas about hard wired circuits have been replaced by circuits that demonstrate a high degree of flexibility in response to neuromodulators and sensory feedback. Identified neurons and synapses, a ...

The rare-earth bis(alkyl) compound Sm{C(SiHMe2)3}2THF2 (1b) is prepared by the reaction of samarium(II) iodide and 2 equiv of KC(SiHMe2)3. This synthesis is similar to that of previously reported Yb{C(SiHMe2)3}2THF2 (1a), and compounds 1a,b are isostructural. Reactions of 1b and 1 or 2 equiv of B(C6F5)3 afford SmC(SiHMe2)3HB(C6F5)3THF2 (2b) or Sm{HB(C6F5)3}2THF2 (3b), respectively, and 1,3-disi...

A series of homoleptic rare-earth silazido compounds and their silica-grafted derivatives were prepared to compare spectroscopic and catalytic features under homogeneous and interfacial conditions. Trivalent tris(silazido) compounds Ln{N(SiHMe2)tBu}3 (Ln = Sc (1), Y (2), Lu (3)) are prepared in high yield by salt metathesis reactions. Solution-phase and solid-state characterization of 1− 3 by N...
