Metallaborane reaction chemistry. A facile and reversible dioxygen capture by a B-frame-supported bimetallic: structure of [(PMe2Ph)(4)(O-2)Pt2B10H10] [PDF]

open access: yes, 2004
[(PMe2Ph)(4)Pt2B10H10] 1 reversibly takes up atmospheric dioxygen to give the fluxional dioxygen-dimetallaborane complex [(PMe2Ph)(4)(O-2)Pt2B10H10] 2, which has Pt-Pt 2.7143(3), Pt-O 2.141(4) and 2.151(4) and O-O 1.434(6 ...

Pd/Pt IMBALANCE IN LAVAS AND INTRUSIONS OF THE NORILSK-TALNAKH ORE REGION

open access: yesГеодинамика и тектонофизика, 2021
The paper considers the Pd/Pt ratio in the ores of the Norilsk-1 and Talnakh deposits associated with the Permian-Triassic intrusions of the Norilsk type in comparison with that in the lavas of the same age in the Norilsk region.

Sandwich semigroups in locally small categories II: Transformations

open access: yes, 2018
Fix sets $X$ and $Y$, and write $\mathcal{PT}_{XY}$ for the set of all partial functions $X\to Y$. Fix a partial function $a:Y\to X$, and define the operation $\star_a$ on $\mathcal{PT}_{XY}$ by $f\star_ag=fag$ for $f,g\in\mathcal{PT}_{XY}$. The sandwich

Investigation of induced Pt magnetic polarization in Pt/Y3Fe5O12 bilayers

open access: yes, 2012
Using X-ray magnetic circular dichroism (XMCD) measurements, we explore the possible existence of induced magnetic moments in thin Pt films deposited onto the ferrimagnetic insulator yttrium iron garnet (Y3Fe5O12).
