Acoustic Absorption of Vertical Gardens
Revista Elektrón, 2019 Los jardines verticales forman parte de una de las tendencias tecnológicas constructivas más modernas, conocidas como “Greenery Systems”. Estas son aplicadas cada vez con más frecuencia en aquellas construcciones donde se priorizan consideraciones energéticas y ecológicas conciliables con el medio ambiente. Algunas de las características relevantes que

Analytical Expression for Sound Transmission Loss Calculation: An Improvement to the Existing Method after Singh and Katra [PDF]
, 2009 An analytical expression for measuring of sound transmission loss (TL) has been developed by using two microphones, an impedance tube and an impulse sound source as a proposed improvement to the existing procedure after Singh and Katra (1978).

Advanced Functional Materials, EarlyView.Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Acoustic Absorption and Dynamic Viscosity in Polymers [PDF]
The Journal of the Acoustical Society of America, 1966 We have obtained results that show that acoustic absorption in linear polysiloxanes varies with viscosity and frequency in a unique manner. At any constant temperature, a significant relaxation is found, with a broad spectrum of relaxation frequencies.

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3
Advanced Functional Materials, EarlyView.Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.
