V 453 Scorpii

open access: yes, 1962
Spectra taken in Bosque Alegre and in California (Lick and Mount Wilson) have made it possible to make a new determination of the orbital elements of V 453 Scorpii and have yielded an improved value for the period. The spectrum of the primary component displays only absorption lines and corresponds to an early type supergiant while the spectrum of the ...

Ir Complexes With Mixed‐Valent Bidentate Ligands: From Complex Synthesis to Catalytic Application

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The bidentate ligands Ph2P(E)NHPPh2 (E = S, Se) feature phosphorous atoms in two different oxidation states and provide the potential to tune chemical reactivity through the choice of donor E. The mononuclear complexes [Ir(COD){κ2‐P,E‐Ph2P(E)NPPh2}] (E = S 1a, Se 1b) were prepared from the dimer [IrClCOD]2 (COD = 1,5‐cyclooctadiene) and the ...

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...
