Awesome
Good amount of activities, involving lectures, makes it easy and understandable even though he has such a large class.
Biography
Georgia Institute of Technology - Materials Engineering

Dr. Mark D. Losego is an assistant professor in the School of Materials Science and Engineering at Georgia Tech. The Losego research lab focuses on materials processing to develop novel organic-inorganic hybrid materials and interfaces for microelectronics, sustainable energy devices, national security technologies, and advanced textiles. The Losego Lab combines a unique set of solution and vapor phase processing methods to convert organic polymers into organic-inorganic hybrid materials, including developing the science to scale these processes for manufacturing. Prof. Losego’s work is primarily experimental, and researchers in his lab gain expertise in the vapor phase processing of materials (atomic layer deposition, physical vapor deposition, vapor phase infiltration, etc.), the design and construction of vacuum equipment, interfacial and surface science, and materials and surface characterization. Depending on the project, Losego Lab researchers explore a variety of properties ranging from electrical to electrochemical to optical to thermal to sorptive to catalytic and more.
Prof. Losego received his B.S. degree in materials science and engineering from Penn State University in 2003 (with a focus on electronic and photonic materials), earned an M.S. (2005) and Ph.D. (2008) in materials science and engineering from North Carolina State University (primarily in vapor phase deposition of functional oxide thin films), and completed postdoctoral studies at the University of Illinois (studying chemical surface modifications and nano-scale thermal transport across hybrid interfaces). Prior to joining the faculty at Georgia Tech, Prof. Losego was a research assistant professor in the Department of Chemical and Biomolecular Engineering at North Carolina State University where he led research efforts in using atomic layer deposition (ALD) to stabilize molecular catalysts for photoelectrochemical energy systems.
Prof. Losego is also the faculty founder and director of The Materials Innovation and Learning Laboratory (The MILL), an open-access make-and-measure facility operated by and for students with the goal of elevating experiential education and undergraduate student research. Encompassing over 1000 sq. ft of space in the Love Manufacturing Building, The MILL is staffed by over 40 undergraduate students and is open 30+ hours per week for all students on campus to learn and do materials processing, characterization, and property measurement.

High performance photocatalytic metal oxide synthetic bi-component nanosheets formed by atomic layer deposition
Synthetic nanosheets that are ultrathin variants of bulk materials have been acquired using atomic layer deposition (ALD) on dissolvable substrates with a control over layer dimension including single and bilayered “Janus nanosheet” structures. TiO2
ZnO
Al2O3 and TiO2/ZnO nanosheets function as dispersible photocatalysts in aqueous media showing 3× synergistic rate enhancement for bilayered nanosheets.

Optimizing phase and microstructure of chemical solution-deposited bismuth ferrite (BiFeO3) thin films to reduce DC leakage
Ambient humidity and high temperature are known to degrade dye-sensitized solar cells (DSSCs) via chromophore desorption. Recently
enhanced dye-attachment to TiO2 surfaces has been realized by coating molecularly functionalized surfaces with inorganic atomic layer deposition (ALD) coatings. Here
we apply this ALD approach to DSSCs and demonstrate that high energy conversion efficiencies can be maintained while significantly extending device lifetimes. While single component ALD layers show improved high-temperature stability
it significantly degraded up to 45% of initial DSSC performance right after ALD. We
however
find that mixed component ALD layers provide initial efficiencies within 90% of their untreated counterparts while still extending device lifetimes. Optimized ALD protection schemes maintain 80% of their initial efficiency after 500 h of thermal aging at 80 °C whereas efficiency of DSSCs with no ALD protection drop below 60% of their initial efficiencies. IR spectroscopy conducted in situ during ALD reveals that carboxylate linker groups transition from unbound or weakly-bound states
respectively
to more strongly bound bidentate structures. This strategy to improve dye-attachment by ALD while maintaining high performance is novel and promising for extending the functional lifetime for DSSCs and other related devices.
