Following a novel synthetic strategy where the strong uniaxial ligand field generated by the Ph3SiO(Ph3SiO= anion of triphenylsilanol) and the 2,4ヾi‐tBu㏄hO(2,4ヾi‐tBu㏄hO= anion of 2,4ヾi‐tertbutylphenol) ligands combined with the weak equatorial field of the ligand LN6, leads ...
If a single electrons are present in the orbitals, they are called unpaired electrons. In the strong field, the crystal field splitting energy is very high, so the electrons can paired up in the orbitals and if weak field is present, then single el...
Weak electronic correlations and absence of heavy-fermion state in KNi_2Se_2 We have studied the low-lying electronic structure of a new ThCr_2Si_2-type superconductor KNi_2Se_2 with angle-resolved photoemission spectroscopy. Three ... Q Fan,XP Shen,MY Li,... - 《Physical Review》 被...
Another consequence of the weak anti-bonding VBM character in disordered NaBiS2, however, is the facilitated emergence of localised Spstates just above the ‘bulk’ or ‘delocalised VBM’ (Figs.1e,2aand Supplementary Fig.5) at Na+-rich pockets (see next section for a detailed discussion). ...
First, the ratio between the coupling strength and dissipation rates g/Γ. The coupling strength is an order of magnitude larger than the dissipation rates which separates the coupling from a weak Purcell effect g/Γ<1. Second, the value of cooperativity C or coherence measurement parameter U=...
Finding the rules for peptide generation and selection is regarded as the most important open issue in the field of HLA-I biology by leading experts (5). Although the antigen presentation pathway is well characterized, it is still unclear how basic properties such as protein abundance, turnover...
Following a novel synthetic strategy where the strong uniaxial ligand field generated by the Ph3SiO- (Ph3SiO-=anion of triphenylsilanol) and the 2,4-di-Bu-t-PhO- (2,4-di-Bu-t-PhO-=anion of 2,4-di-tertbutylphenol) ligands combined with the weak equatorial field of the ligand L-N6...
Do similar functional roles of neurons with weak and strong population coupling exist in motor cortex? Although previous studies demonstrate that correlations among single units can have a role in motor coding (e.g., refs. 27,28), and that some neurons in motor cortex appear to be more ...
Strong field ligands such as CN-: (a) usually produce high spin complexes and small crystal field splittings. (b) usually produce low spin complexes and small crystal field splittings. (c) usually produce low spin complexes and high crystal field split Compound (C...
