Iridium-catalyzed enantioconvergent hydrogenation of trisubstituted olefins

open access: yesNature Communications, 2022
Usually asymmetric hydrogenation of olefins is enantiodivergent and thus requires isomerically pure olefins, which is a considerable drawback. Here, the authors show a general iridium-catalyzed enantioconvergent hydrogenation of a broad range of ...

Temperature-Dependent Activity of Motor Proteins: Energetics and Their Implications for Collective Behavior

open access: yesFrontiers in Cell and Developmental Biology, 2021
Molecular motor proteins are an extremely important component of the cellular transport system that harness chemical energy derived from ATP hydrolysis to carry out directed mechanical motion inside the cells. Transport properties of these motors such as

Convex Arrhenius plots and their interpretation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
This paper draws attention to selected experiments on enzyme-catalyzed reactions that show convex Arrhenius plots, which are very rare, and points out that Tolman's interpretation of the activation energy places a fundamental model-independent constraint on any detailed explanation of these reactions. The analysis presented here shows that in such

Characterization of Aluminized Layers on Inconel‐738 Alloy: Microstructure, Modeling of Aluminizing Kinetics, and Thermal Behavior

open access: yesAdvanced Engineering Materials, EarlyView.
This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...
