wherein M represents a transition metal of the group V of the Periodic Table; R represents a cyclopentadienyl group, a substituted cyclopentadienyl group, an indenyl group, a substituted indenyl group, a fluorenyl group or a substituted fluorenyl group; O represents an oxygen atom; X represents...
e Normalized quasi-1D localization length Λ’s as functions of θ at different transversal system sizes L. The used longitudinal system size is M = 107 and the precision (σΛ/Λ) has reached 1%. (For network model, `size’ refers to the number of squares.) Λ only depends on ...
a, Periodic table showing the metals (highlighted in brown) and chalcogens (highlighted in blue) that have the possibility of forming layered sulfides, selenides and tellurides. b–m, AFM images and height profiles (insets) of 12 types of telluride, selenide and sulfide nanosheet. b, Mo0.5...
PROBLEM TO BE SOLVED: To provide a periodic table group 13 metal nitride semiconductor crystal in which dislocation that has an edge component that influences device property is decreased, and that can exert the excellent device property.NAGAO SATORU...
Run through the DST string or completion on wireline, therefore restricted in size to fit through the drift ID of the string. • Charges are small; therefore the perforating performance is commensurately less than that of casing guns. • Short exposure time for the explosives to high temper...
Interestingly, an fcc to distorted fcc transition has been observed to occur in La [23] and Pr [24], the elements on either side of Ce in the periodic table, as well as in cerium-based alloys [25] and δ-Pu [26]. The second question is a logical progression of the first. If ...
To estimate the atomic charges of MOFs, the Extended Charge Equilibration (EQeq) method is utilized. Additionally, electrostatic interactions were measured using the Ewald summation method, which ensured an accuracy of 10−4 kcal/mol31,34. Both the equilibration and production steps were conducted...
Current research efforts on single-atom catalysts (SACs) exclusively focus on nonmetal or transition-metal atoms as active centers, while employing main-group metal elements is seemingly excluded because their delocalized s/p-bands are prone to yield a broadened resonance for the interaction with adso...
A Periodic Table Group 13 metal nitride crystal is grown by causing a reaction of a Periodic Table Group 13 metal phase with a nitride-containing molten salt phase to proceed while removing a by-product containing a metal element except for Periodic Table Group 13 metals, from the reaction ...
