Andrei Kolmakov

 Position:                   Associate Professor                             at SIUC since 2005

 

 Research Interests:   • Understanding of chemical sensing and catalysis with low dimensional materials

 Brief bio:                Andrei Kolmakov is currently an Associate Professor at the Department of Physics, Southern Illinois University  Carbondale.  Graduated from Moscow Institute of Physics & Technology (MIPT). Combining his postgraduate studies at MIPT and work as a staff member at Kurchatov Institute (Moscow) he received his PhD in solid state physics in 1996.  During his postdoctoral work at European synchrotron radiation centers in the groups of Dr. Maya Kiskinova (ELETTRA) and Prof. Thomas Moeller (HASYLAB) he was studying  the surface, interfacial and kinetics processes on supported nano-(meso) particles and free clusters using photoelectron spectroscopy, XANES and imaging PEEM / SPEM techniques. In 1999 he joined the group of Prof. Wayne Goodman at Texas A&M University to conduct in situ STM studies on supported metal clusters under reaction conditions.  In 2001 his was invited to UCSB  to launch scanning tunneling microscopy part of AFOSR funded program on catalysis by nanostructures which also resulted in 2002 in fabrication of one of the first metal oxide nanowire based chemical sensor and catalyst (together with Prof. Martin Moskovits). He joined the faculty of the Department of Physics, Southern Illinois University at Carbondale in 2005. Prof.  Andrei Kolmakov is mainly known for his work on gas sensing and catalysis by metal oxide nanowires. In addition to active materials research and studies of nanoscopic sensors and analytical devices, Kolmakov’s group is actively working on development of the methodology and hardware for in situ / in vivo spectromicroscopy of the nanostructures under real world conditions, fully hydrated objects and nanodevices under operating conditions.   Prof. A. Kolmakov published over 80 papers, 5 review articles and 2 book chapters with total citation index over 2000. For complete CV click here

	We developed a simple environmental cell with electron transparent graphene oxide windows and  demonstrated the feasibility of in situ X-ray photoelectron spectroscopy measurements through the membrane on wet samples. These proof-of-principle results show the potential of low-cost E-cells compatible with commercial  electron  microscopes [1].		Congratulations to Shannon Berg the winner of the 1st prize awarded at St. Louis Area Undergraduate Research Symposium (StLAURS) for her work: Development of Techniques for Scanning Electron Microscopy of Fully Hydrated Plant Samples: Phytotoxicity of Silver Nanoparticles Case Study. http://reach.siuc.edu/
	Real time optical and XPEEM microscopy revealed intriguing particularities of VO2 meso- and nanostructure growth. For details check: [2] below		We dedicate significant effort to develop  the new experimental techniques, methods and instrumentation. The recent work in collaboration with Mr. C. Watts resulted in design of a compact microscope hot stage (temperature up to ca 1000 °C) which can be coupled with high magnification optical or electron microscope for in situ studies of nanostructures growth. See supporting material in [2]
	The simplest and yet fully functioning "electronic nose" has been fabricated out of a single  SnO2 nanobelt. Reed more in  [7]		The deeper insight into the interplay between the domain formation and metal insulator transition in VO2 has been achieved in cooperation with Functional Imaging on the Nanoscale Group at ORNL. See details in:[3],[6],[9]
	This collaborative work with the group of Prof. M. A. Alam  (Purdue University) led to deeper understanding of the role of   NW-to- NW junctions, in the  response of percolating NW network chemical sensors. See details in: [12]		We are extanding WETSEM methodology to observe the processes inside the macroscopic samples such as living plant roots. See details in collaborative phytotoxicity study: [8]
	In this communication we demonstrate the capabilities of SEM to image in situ the  processes in liquids. Read more in the invited article: [5]		Based on Dr. V. Sysoev et. al. original work,    the "electronic nose" student team: E. Strelcov, R. Favreau, G. Montgomery won fourth place among 22 finalists from five countries competing for cash prizes at the the Global Venture Challenge 2010 ORNL contest, aimed at finding innovative ideas from graduate students to address the world’s needs for energy and security.
