Title: Najib Alia and Acoustic Particle Detection for Nanoparticles in Liquids.

Introduction

Najib Alia is an inventor associated with Weil-am-Rhein, Germany, and Ovivo Inc. His patent work addresses the detection of particles in liquids, including applications that require ultra-high-purity water in semiconductor manufacturing.

Latest Patents

The provided information lists one patent for Alia: “Acoustic Particle Counter for Nanoparticles in Liquids.” The invention uses a sensor unit that receives a controlled flow of water through a measurement cell. A transducer delivers an acoustic pulse at a known intensity, focused on the liquid to induce cavitation if a particle detectable at that intensity is present. A waveform emitter and receiver sends the high-frequency, high-voltage signal to the transducer and detects echoes that indicate a cavitation event. A microprocessor controls the system. The approach is designed to identify particles of specified sizes, including nanoparticles, in high-purity water.
