About

Maike Siemons is a materials scientist whose research has made meaningful contributions to the field of gas sensing, with a particular focus on the synthesis and characterization of novel metal oxide materials. Her work centers on engineering nanocrystalline and volume-doped perovskite-type oxides — most notably cobalt titanate (CoTiO3) — to optimize their sensitivity and selectivity as gas sensing materials. Through innovative synthesis approaches such as the polyol method, Siemons demonstrated how controlled doping with rare-earth elements like lanthanum could significantly enhance the gas sensing performance of these materials at the nanoscale. Her 2007 study on volume-doped CoTiO3 has garnered 75 citations, while her complementary 2006 investigation into La-doped nanocrystalline variants has accumulated 58 citations, reflecting sustained interest from the sensing community. Beyond materials synthesis, Siemons also advanced the methodological toolkit of the field by developing a High-Throughput Impedance Spectroscopy Screening System (HT-IS), enabling more efficient identification and characterization of promising new sensing materials. Her body of work represents an important bridge between nanomaterials chemistry and practical sensor technology development.
