Thermocavitation

Our interest is to develop needle-free methods for liquid jet injection using microfluidic devices and thermocavitation, with relatively low laser energy and low cost of fabrication for an injection device. The first results can be seen here.

Energy

The generation of Hydrogen powered by sunlight and using water is an ideal example of zero-emission energy technology.
Our work in this direction covers the fundamentals of hydrogen evolution on functionalized electrodes and the design and construction of microfluidic devices prototypes that can be scaled up in a not so far future.

Microfluidics

I currently collaborate with other colleagues in the design and fabrication of microfluidic devices for the generation of mono disperse droplets, and other useful applications. One example of this collaboration can be seen here.

Sonochemistry & Cleaning

WHAT?

I want to control better the growth and collapse of a bubble, known as cavitation.Bubble surface modification
Bubbles collapsing near surfaces can modify surface properties, which has applications of scientific and economical relevance.

WHY?

Bubbles can be used for cleaning of 3D printed parts, medical tools, or other important applications such as cell manipulation, and water treatment (see Sonochemistry).

CAN BUBBLES CLEAN?
HOW?

A short story about ultrasonic cavitation:

KNOWLEDGE TRANSFORMED INTO A COMMERCIAL PRODUCT?

The BuBle Bag is a good example of knowledge valorisation, with more than 10,000 sold!

 

The uses of ultrasound in chemistry cover several applications such as degradation of contaminants in water treatment, nanomaterials synthesis, and the food industry.

I want to innovate in the Sonochemistry activities with microfabrication and microfluidic techniques.
