Enhancing STEM Education with Tabletop SEM at Queensborough Community College

The Hitachi TM-1000 tabletop scanning electron microscope (SEM) at QCC facilitates research in materials chemistry and geological science, expanding STEM activities for grades 7-12. The SEM, along with a sputter coater, supports projects studying organic and inorganic nanomaterials, conducting polymer nanomaterials, metal salts, and biosensor applications. Through this acquisition, students from underrepresented groups have enhanced access to microscopy, fostering their participation and research presentations in STEM. The student-centered approach at QCC promotes a hands-on educational experience and ownership of research projects.

  1. Acquisition of a Tabletop Scanning Electron Microscope for Undergraduate Research and Training in Materials Chemistry and Geological Science and STEM Activities in Grades 7-12 David M. Sarno, Queensborough Community College of the City University of New York, DMR 0722607 The Hitachi TM-1000 tabletop scanning electron microscope is well-suited to a teaching institution with limited research facilities. Up to 10,000x magnification is possible on an instrument that is inexpensive, simple to operate, and requires minimal maintenance. Also acquired was a sputter coater to improve imaging of non-conductive samples. Studies in materials chemistry and geology have been greatly facilitated by this acquisition. Major projects in the first year have included the morphological char- acterization of organic and inorganic nanomaterials. Several conduct- ing polymer nanomaterials have been studied as the basis for hybrid materials with possible biosensor applications. Metal salts reduced and stabilized by siloxane oligomers have yielded micron and nano-scale metal particles for catalysis.

  2. Acquisition of a Tabletop Scanning Electron Microscope for Undergraduate Research and Training in Materials Chemistry and Geological Science and STEM Activities in Grades 7-12 David M. Sarno, Queensborough Community College of the City University of New York, DMR 0722607 Acquisition of the TM-1000 tabletop SEM has brought microscopy to the QCC campus. As a non-Ph.D.-granting, minority-serving institution that is 59% female, this instrument is readily accessible to students from underrepresented groups, broadening their participation in STEM fields. In the first project year, five 1st and 2nd-year undergraduates have been trained in its operation and all have presented their research at local, regional, and national ACS meetings. The SEM joins a modern instrumentation lab used for teaching and faculty-mentored research. The student-centered focus of research at QCC promotes a sense of ownership and responsibility for their projects. QCC students presenting their work and operating the TM-1000 SEM
