SAW devices, in which acoustic wave travels along the surface of a material, are used as filters, oscillators and delay lines in electronic circuits. However, recent research [1] revealed that bulk acoustic waves (BAW) can be nonlinearly generated in LiNO3 SAW device if the drive level ... Read More

It is well known that high noise levels can result in psychological and physiological discomforts. Mufflers are used for reducing exhaust noise from automotive engines. Simple expansion chamber is a well-known design of a muffler. However, it fails to perform at frequencies that coincide ... Read More

Soil pipes are large contiguous macropores that exist in soils or geological materials. These macropore features generally serve as conduits for rapid movement of water through soils or geological material, and are generally oriented nearly parallel to the land surface. Soil pipes are ... Read More

From microelectronics cooling to biological analysis and wearable therapeutic infusion systems, micropumps are steadily becoming a valuable and ubiquitous tool for fluid transport and thermal management. Hence, the development of novel actuation mechanisms that allow for precise ... Read More

The setup of the problem: To develop a mathematical model of cerebral cortical folding development, half-hemisphere geometry is used and the outer layer (gray matter) is allowed to move inward under the effect of both physical and biochemical factors. The model is time-dependent, ... Read More

This paper describes a simulation study performed with the goal of quantifying the correlation between violin design and sound quality. The investigation first explored the resonant modes of the front plate of a violin by examining its eigenfrequencies. Chladni patterns of increasingly ... Read More

Introduction: A small-scale supersonic wind tunnel can represent a convenient platform for supersonic flow testing. The scale considered in this work, with maximum cross-sectional area of 1”x1”, requires simpler structure in addition to the low budget costs and minor space ... Read More

A defining characteristic of atomic layer deposition (ALD) is the sequential exposure of a surface to self-limiting, saturating reactions. Temporal ALD operates through intermittent purge cycles, while spatial ALD relies on physical separation accomplished by delivering reactants through ... Read More

Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ... Read More

A technology demonstrator called the “acoustic hyperlens”, constructed using metamaterials, can transform near field waves into far field waves. It is the inherent anisotropic properties of the metamaterial that facilitates this transformation. Prior “acoustic hyperlens” research has ... Read More
