Catalina Gabriela MIHALCEA serves as an Assistant Researcher at the Laboratory of Atomic Structures and Defects in Advanced Materials (LASDAM) within the National Institute of Materials Physics. Her work focuses on advanced nanomaterials for gas sensing and photocatalytic applications, with particular expertise in metal oxide semiconductors including TiO 2 , SnO 2 , NiO, and WO 3 . Her research interests span gas sensing mechanisms (particularly for CO 2 , methane, acetone, and hydrogen), defect engineering in nanomaterials , and photocatalytic performance optimization . Key methodologies include hydrothermal synthesis, co-precipitation, and advanced characterization techniques such as EPR spectroscopy, TEM, and XRD. She investigates how morpho-structural properties, synthesis parameters, and environmental conditions (humidity, temperature) affect material performance. Analysis of her 15 most recent publications reveals a strong emphasis on in-field condition testing using computer-controlled Gas Mixing Systems, with significant contributions to understanding charge carrier trapping in phase-transforming TiO 2 , electrode geometry effects in SnO 2 sensors, and humidity-resistant sensing platforms. Her work demonstrates consistent innovation in sensor design and fundamental material behavior under operational conditions. She actively collaborates with researchers across multiple institutions, evidenced by co-authorship on publications spanning materials synthesis, characterization, and application testing. Her technical contributions include developing synthesis protocols for black TiO 2 with enhanced visible-light photocatalysis and optimizing WO 3 sensors for low-concentration acetone detection in high-humidity environments.
