The uncertainty of sound insulation properties of light weight building elements

, 2014
Measurement uncertainty is an important topic in building acoustics measurements carried out in the field assessing the sound insulation between rooms as well as conducted in test stands characterizing the sound insulation properties of a building element accurately. Beyond measurement method related contributions to the uncertainty budget there is the

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Opportunities for 2D‐Material‐Based Multifunctional Devices and Systems in Bioinspired Neural Networks

Small, EarlyView.
Bio‐inspired computing offers a route to highly energy‐efficient artificial intelligence. The unique physical properties of two‐dimensional (2D) materials can further enhance such computing approaches. This perspective highlights recent developments in 2D materials‐based neuromorphic devices and discusses future opportunities for integrating such novel

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials

Small, EarlyView.
Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Unraveling the Mechanism for Phonon Based Heat Transport in Metal‐Organic Frameworks

Small, EarlyView.
Heat transport in metal‐organic frameworks arises from an interplay between particle‐like phonon propagation and wave‐like inter‐band coupling. Using machine‐learned potentials within a unified phonon‐transport framework based on the Wigner transport theory, we reveal how differences in phonon lifetimes and phonon tunneling effects determine the ...

A Multimodal In‐Situ Liquid Phase TEM and Electrochemical Study on Boric Acid as Electrolyte Additive for Alkaline Zinc‐Air Batteries

Small Methods, EarlyView.
This study establishes a multimodal correlative workflow to bridge disparate analytical scales in battery research. By linking dynamic in‐situ liquid‐phase TEM at the nanoscale with microscale morphological analysis and macroscale electrochemistry, a comprehensive mechanistic evaluation of electrolyte additives is achieved.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...
