Luminescent Manganese(II) Iminophosphorane Derivatives
MoleculesThe reaction between the iminophosphorane ligand N-phenyl-1,1,1-triphenylphosphanimine (NPh=PPh3) and anhydrous manganese(II) halides allowed the isolation of complexes with the general formula [MnX2(NPh=PPh3)2] (X = Cl, Br, I).

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Recovery of manganese from steel plant slag by carbamate leaching [PDF]
"The U.S. Bureau of Mines investigated the feasibility of using ammonium carbamate (NH2CO2NH4) leaching to recovery manganese from steel plant slag. This investigation showed that treatment of the slag in hydrogen prior to leaching enhanced manganese ...

Biochemical Consequences of a Leucine-to-Cysteine Clamp Substitution in Lipoxygenases
BiomoleculesLipoxygenases (LOXs) are a family of metalloenzymes that oxidize polyunsaturated fatty acids producing cell-signaling hydroperoxides. Fungal LOXs have drawn interest because of their roles in plant and animal pathogenesis.

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Characterizing Manganese Cycling During Estuarine Mixing [PDF]
Manganese (Mn) is a trace element essential for life. In the environment, it can exist in three states (Mn(II, III, IV)), with Mn(II) being dissolved, Mn(IV) being particulate, and Mn(III) being particulate unless stabilized by organic molecules known as

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition
Advanced Engineering Materials, EarlyView.AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...
