TL;DR: In this article, the authors show that four effective 55Mn hyperfine tensors (AX, AY, AZ) are required to properly simulate the experimental data and further show that these effective tensors are best supported by a trimer/monomer arrangement of three Mn(IV) ions and one Mn(III) ion.

TL;DR: These pulsed EPR results are used in an evaluation of several recently proposed mechanisms for PSII water oxidation, and strongly favor mechanistic models where the substrate waters bind within the OEC early in the S-state cycle.

TL;DR: In this paper, a resistance variable memory element is provided having at least one silver-selenide layer (18) in between glass layers(17, 20, 21) and a chalcogenide glass, preferably having GexSe100-x composition.

TL;DR: A method of forming resistance changing elements with improved operational characteristics for use in memory devices and the resulting structures are disclosed in this article, where a chalcogenide glass having the formula (Ge x 1 Se 1−x1 ) 1−y1 Ag y1, wherein 18 ≦x l ≦28, or the formula(Ge x 2 Se l−x2 )1−y2 Ag y2, wherein 39 ≦ex 2 ≦42, and wherein in both the silver is in a concentration which maintains the germanium selenide

TL;DR: The study revealed the formation of a Mn(III,IV) dinuclear cluster in direct correlation with expoxide formation and offers insight into the mechanism of catalyst degradation and formation of unwanted byproducts.
