A Novel Macroscale Acoustic Device for Blood Filtration

Resolving macroscale and microscale heterogeneity in virus filtration

In this paper, we characterize the filtration and deposition profiles of a recombinant analog of Norwalk virus, an important waterborne pathogen, in packed beds of saturated quartz sand under both ‘clean-bed’ and ‘dirty-bed’ conditions. Under clean-bed conditions with NaCl as the electrolyte, the retained Norwalk virus particles decline like a power-law with depth. The power-law decay in retain...

A simple and novel method for acoustic streaming power measurement of ultrasonic horn

Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...

A Novel Portable Scissors-Type Fruit Picking Device

At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...

Developing a Device for Automated Peritoneal Dialysis

Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...
