Abstract Noise is an environmental pollutant with recognized impacts on the psychological and physiological health of humans. Many porous materials are often limited by low sound absorption over a broad frequency range, delicacy, excessive weight thickness, poor moisture insulation, high temperature instability, lack readiness for volume commercialization. Herein, efficient robust lamella‐structure reported as acoustic absorber based self‐assembled interconnected graphene oxide (GO) sheets...

Acoustic absorption by a carbon nanotube (CNT) was studied using molecular dynamics (MD) simulations in domain containing monatomic gas driven time-varying periodic force to simulate acoustic wave propagation. Attenuation of the sound and characteristics field due interactions with CNT were evaluating behavior various parameters comparing that without present. A standing model developed for CNT-containing system predict attenuation results verified against estimates thermodynamic concept...
Current studies are aiming to improve the sound absorption of coir fiber by implementing combinations Perforated Plates (PPs) and air gaps.The Atalla Sgrad model along with Johnson-Allard Acoustic Transmission Analysis (ATA) approach used estimate coefficient combination.Measurements conducted in impedance tube validate analytical results.Outcomes show that panel is governed porosities implemented PPs.Reduction porosity face PP causes incident reflect back whereas higher encourages enter be...
Breast cancer is among the deadliest cancers worldwide, highlighting urgent need for effective treatments. This study employs density functional theory (DFT) and molecular docking analyses to evaluate anti-cancer efficacy specificity of drug molecules lapatinib, tucatinib, neratinib, anastrozole, letrozole. DFT analysis provides comprehensive insights into structural, electronic, optical, vibrational properties these drugs, helping elucidate their stability reactivity through global...
Coir fiber from coconut husk is an important agricultural waste in Malaysia. The porous structure of makes it eligible material for acoustical absorption. In previous studies at Universiti Kebangsaan Malaysia, single layer coir showed low absorption medium and frequencies; e.g. coefficient a 20 mm industrial prepared sample was below 0.3 frequencies less than 1.5 kHz. Current research initiated to improve the shortcoming by mixing with air gap layers. Analyzes were based on two approaches,...
Coir fiber is one of the natural fibers that can be easily found in tropical countries like Malaysia. This study illuminates acoustical absorption coir throughout frequency spectrum. The empirical Delany-Bazley method together with Allard elastic model were two analytical approaches implemented this research. Outputs techniques validated by impedance tube measurements. Both methods able to show general pattern but existing frame resonance/resonances could only predicted as does not take...
Molecular dynamics (MD) simulations have been performed to study sound wave propagation in a simple monatomic gas (argon) and the thermo-acoustic effects on single walled carbon nanotube (CNT). The objective of this was understand acoustic behavior CNTs presence waves propagating gaseous media. A plane generated within rectangular domain by oscillating solid wall comprising Lennard-Jones (LJ) atoms with same intermolecular potential as molecules. CNT aligned parallel direction flow at...
The propagation of internal waves in the ocean can produce significant fluctuations local sound speed field. Understanding how these affect acoustic is an area considerable interest underwater acoustics. Previous studies have indicated that large (of order 20 dB) transmission loss (TL) occur due to focusing and defocusing effects as propagate through wave. This work looks extend some by exploring frequency directional dependence implementation a 3D model (FOR3D) suitable for modelling low...
