A Dynamic Surface Metal‐Organic Framework Electrocatalyst: Potential‐Driven Activation of Atomically Defined Au Sites for the Hydrogen Evolution Reaction

Small, EarlyView.
Operando EC‐STM reveals that an NHC‐based SMOF on Au(111), initially frozen in interconnected 1D chains, dynamically reconfigures under cathodic bias into a fluxional structure bearing undercoordinated Au sites while abstracting Au atoms from the support.

Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

Small, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

From mystery to modulation: the structural story of Rb2[Si2O5]

Acta Crystallographica Section B, EarlyView.
The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...
