Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

open access: yessteel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

High‐Yield Assembly of Plasmon‐Coupled Nanodiamonds Using DNA Origami for Tuned Emission

open access: yesSmall Structures, EarlyView.
Engineering assemblies of single‐photon emitters and plasmonic elements with nanometer precision opens pathways for quantum sensing and photonics applications. A surface functionalization strategy is established for grafting DNA onto nanodiamonds, and their placement on DNA origami is optimized to achieve yields above 50%.

Capital stranding cascades: The impact of decarbonisation on productive asset utilisation [PDF]

open access: yes, 2019
This article develops a novel methodological framework to investigate the exposure of eco- nomic systems to the risk of physical capital stranding. Combining Input-Output (IO) and network theory, we define measures to identify both the sectors likely ...

The need for multi‐method extreme event attribution

open access: yesWeather, EarlyView.
Over the past 20 years, extreme event attribution has developed rapidly, providing a wide range of methods to attribute weather events – from unconditioned probabilistic to strongly conditioned storyline approaches. Advancing the field now requires combining results from multiple methods, allowing more robust conclusions drawing from various lines of ...
