A comparison of impedance boundary conditions for flow acoustics [PDF]
, 2013 Acoustic liners remain a key technology for reducing community noise from aircraft engines. The choice of optimal impedance relies heavily on the modeling of sound absorption by liners under grazing flows.

Advanced Materials, EarlyView.A new benign solvent (1,3‐diphenylacetone) enables a simple, safe, and sustainable dissolution and gelation method to convert waste PET into low density, monolithic aerogels with high mechanical strength (E = 20 MPa) and remarkably low thermal conductivity (k = 21.9 to 28.9 mW/m·K).

Experimental analysis of noise reduction properties of sound absorbing foam [PDF]
, 2001 Plan BWood dust deposition had both positive and negative effects on the sound absorption properties of acoustical foam. Three layers of wood dust were deposited on acoustical foam in a 2.44 meter by 2.44 meter by 2.44 meter Plexiglas test chamber.

Factors affecting the sound insulation in the prefabricated buildings
Budownictwo i Architektura, 2014 The sound insulation in buildings is affected by many factors related to various sound transmission paths between rooms. Among them the following paths can be distinguished: the so called direct path dependent on the sound insulation of the partition ...

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles
Advanced Materials, EarlyView.Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.

Advanced Materials, EarlyView.This study presents a compact dynamic‐field‐driven nucleation and growth (DFNG) model that captures ferroelectric switching behavior under arbitrary voltage waveforms. It enables extraction of time‐dependent domain wall velocity and growth dimensionality, which can then be extended to device‐level modeling.
