Optimisation of a two-wire thermal sensor for flow and sound measurements [PDF]
, 2001 The Microflown is an acoustic sensor measuring particle velocity instead of pressure, which is usually measured by conventional microphones. In this paper an analytical model is presented to describe the physical processes that govern the behaviour of ...

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.This study analyzes the impact of orographic drag on the lower atmosphere over moderately complex terrain using high‐resolution ICON simulations. Numerical simulations explore the effects of parametrizations over moderately complex terrain near the Perdigao experiment site and the Serra da Estrela mountain range by comparing km‐ and 100‐m‐scale ...

Strain, Volume 61, Issue 2, April 2025.ABSTRACT The present paper investigates the low‐velocity impact behaviour and the compression‐after‐impact (CAI) behaviour of carbon‐fibre reinforced‐plastic (CFRP) composite panels after two impacts in different locations on a test coupon. The effect of changing the separation distance between the two impacts, as well as changing the impact energy, is

Improving CO2 Fixation with Epoxides by Replacing Zirconium by Hafnium in UiO66 MOFs
ChemCatChem, Volume 17, Issue 5, March 6, 2025.Substituting Zr⁴⁺ with Hf⁴⁺ in UiO66‐NH₂ functionalized with N,N'‐dicyclohexylcarbodiimide (DCC) and N,N'‐diisopropylcarbodiimide (DIC) significantly enhances CO₂ adsorption and catalytic activity. Hf‐based catalysts, UiO66(Hf)‐DCCBr and UiO66(Hf)‐DICBr, possess stronger Lewis acidity and oxophilicity leading to high TOFs and yields under 0.1 MPa CO₂ ...

ChemCatChem, Volume 17, Issue 5, March 6, 2025.Phosphine and phosphine oxide‐decorated polymer‐immobilized ionic liquid stabilized AuNPs are highly selective catalysts for the solvent‐dependent partial reduction of nitrobenzene to N‐phenylhydroxylamine in water and azoxybenzene in ethanol. Catalysts generated from phosphine oxide‐decorated support impregnated with either Au(I) or Au(III) are ...

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 3, March 2025.Abstract We evaluate the performance of various configurations of the Canadian Regional Climate Model (CRCM6‐GEM5) in simulating 10‐m wind speeds using data from 27 AmeriFlux stations across North America. The assessment employs a hierarchy of error metrics, ranging from simple mean bias to advanced metrics that account for the dependence of wind ...
