Modified transition state theory and negative apparent activation energies of simple metathesis reactions: Application to the reaction CH₃ + HBr + CH... A modified transition state theory (MTST) has been developed for gas-phase reactions with "negative barriers". The theory was applied to the...
1O2, an excited state of O2, is a mild and selective oxidant and is resistant to saturated alcohols (methanol or ter-butanol) (Duan et al., 2018a). The lifetime of 1O2 is about 3 μs in water, which is much shorter than that in air (Nosaka and Nosaka, 2017). 1O2 has been...
As far as we know, this is the first time that solid evidence has been provided for the identification of the Mn oxidation state during the Mn DMD process in LMO-based cells. It should be mentioned that there are a few studies that reported the observation of Mn2 þ / Mn3 þ ...
The Weyl semimetal (WSM) state occurs in two situations, requiring either a broken time-reversal symmetry (TRS) or a broken spatial IS; the latter has been established in weakly interacting electron systems with spectroscopic evidence of Weyl fermions. The experimental quest for a TRS-breaking WSM...
Purified oxygen-evolving CP43-E354Q PSII core complexes exhibited a slightly altered S(1) state Mn-EXAFS spectrum, a slightly altered S(2) state multiline EPR signal, a substantially altered S(2)-minus-S(1) FTIR difference spectrum, and an unusually long lifetime for the S(2) state (...

However, worldwide sales of EVs have been significantly restricted by the high cost, short recharge mileage, and poor durability of current state-of-the-art LIBs—problems that derive from the cathode [4]. Consequently, LiNixCoyMn1-x-yO2 (x ≥ 0.9) nickel-rich ternary layered ...

On the basis of the average Mn oxidation state of 3.62 ± 0.065, which was estimated from a redox titration and the composition of LMO(2.3 nm) (Li/Mn = 0.463 (mol/mol)), which was from elemental analyses, the empirical formula of LMO(2.3 nm) was deter- LmMinO...
Accept all cookies details Abstract The dice lattice, containing a stack of three triangular lattices, has been proposed to exhibit nontrivial flat bands with nonzero Chern numbers, but unlike the honeycomb lattice it is much less studied. By employing density-functional theory (DFT) calculations ...
