This study investigates the effect of ultrasonication and microwave sludge disintegration/pre-
treatment techniques on the anaerobic co-digestion efficiency of wastewater sludges with …

Application of low-frequency ultrasound has been shown to enhance transdermal drug
transport of large molecules such as insulin. In this study, we investigated the dependence …

Rotary ultrasonic machining (RUM) has been investigated in machining of brittle, ductile, as
well as composite materials. Ultrasonic vibration amplitude, as one of the most important …

The use of low‐frequency ultrasound has been proposed to enhance the transdermal
transport of various drugs, a technique referred to as sonophoresis. The aim of the present …

Rotary ultrasonic machining (RUM) has been used to machine both brittle and ductile
materials as well as composite materials. There are numerous reported studies about the …

Repeated insulin injections remain painful for diabetic patients. Intensive research has been
focused on the transdermal route as a possible way to drug delivery. For several years now …

Flexural horn-type transducer is widely applied in high-power ultrasonic field. In this paper,
an acoustic emission (AE) sensor acts as a non-contacting piezoelectric sensor responding …

Several studies have demonstrated that low frequency ultrasound (20 kHz) can increase
skin permeability leading to the idea that the phenomena called phonophoresis could …

This report documents the results of a literature survey into optical methods for the
measurement of acoustic parameters ion air and water. The report reviews existing methods …

In recent years, the main processing methods for difficult-to-machine materials have focused
on the field of ultrasonic-assisted processing. Ultrasonic stack, the key part in ultrasonic …
