Acoustical characteristics of guns as impulse sources

open access: yes, 1985
The acoustical characteristics of five guns, including three calibres and two gun types, were measured to determine their suitability as impulse sources. Comparisons were made with spark and loudspeaker impulse sources. One 0.38 calibre revolver was found to be a suitably repeatable, omni- directional impulse source providing adequate sound energy in ...

Characteristic function of impulse responses in churches

open access: yes, 2020
The tool presented enables the sound behaviour of a room to be objectified on the basis of the representation of the characteristic function (CF) of said room.In this paper, we study characteristic functions, defined from the impulsive responses measured at different points in the room, that are obtained in churchesand cathedrals.

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...
