Acoustic Metasurface-Aided Broadband Noise Reduction in Automobile Induced by Tire-Pavement Interaction (open access)

Acoustic Metasurface-Aided Broadband Noise Reduction in Automobile Induced by Tire-Pavement Interaction

Article demonstrating a technique utilizing acoustic metasurfaces (AMSes) with high reflective characteristics using relatively lightweight materials for noise reduction without any change in mechanical strength or weight of the tire. The proposed design can significantly reduce the noise arising from tire–pavement interaction over a broadband of acoustic frequencies under 1000 Hz and over a wide range of vehicle speeds using a negative effective dynamic mass density approach.

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile (open access)

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile

This article's aim is to determine whether (a) the spatial use of domestic dogs increases with habitat destruction, and (b) domestic dogs and habitat destruction drive the spatial use of native carnivores in a heavily degraded agricultural landscape. Conclusions highlight that domestic dog occupancy was positively correlated with habitat loss and future conditions of increased fragmentation and habitat loss will likely increase the potential contact between domestic dogs and native carnivores.

Further Analysis on Solubility Measurement and Thermodynamic  Modeling of Benzoic Acid in Monosolvents and Binary Mixtures (open access)

Further Analysis on Solubility Measurement and Thermodynamic Modeling of Benzoic Acid in Monosolvents and Binary Mixtures

Article discussing further analyses of the recent report (by Sandeepa et al.) on the solubility of benzoic acid in six monosolvents (i.e. tributyl phosphate, diacetone alcohol, methyl-n-propyl ketone, methyl acetate, amyl acetate, and isooctane) and five binary systems (i.e. ethanol + hexane, isopropyl alcohol + hexane and chloroform + hexane, acetone + hexane, and acetone + water) along with some numerical analyses. The reported calculations have been reanalyzed based on combined nearly ideal binary solvent/Redlich-Kister, the modified Wilson model, general single model, Jouyban–Acree model and Jouyban–Acree–van’t Hoff model. The investigated models provide good estimation of the solubility behavior of benzoic acid in the binary solvent mixtures at various temperatures.
