I would like to say thank you to all of you who have helped me so far with my thesis on the movement and concentration of suspended particles in the nodal planes of an ultrasonic standing wave field and on my design project. Thank you for answering all the questions that I posted in Researchgate. You guys helped me in understanding my thesis further when the thesis was not a group project, but an individual project. Thank you very much. If we were in the same university, I would have met with you and give my thanks. And a picture as well hehehe :)
Sincerely,
Badri Suhaini
