August 20, 2017 - We received funding from the UMD-UMB seed grant to work on imaging protein aggregates with liquid cell electron microscopy. We will collaborate with Bruce Yu's group in Pharmaceutical Sciences at UMB to develop new analytical methods to assess the aggregation state of protein-based drugs. Congrats!

June 26, 2017 - Our lab won a DOE User Proposal grant to work with our collaborator Ray Unocic at Oak National Lab to investigate nucleation mechanisms with liquid cell electron microscopy. Mei and Dr Woehl will be traveling to ORNL this coming academic year to do experiments. Congrats!

June 16, 2017 - Sushanth Gupta and Kingsley Ojibeka join our lab as high school students from Montgomery Blair High School and Eleanor Roosevelt High School to do summer research internships. Welcome!

May 30, 2017 - Our lab received funding for our electrocatalysis and in situ TEM research from the Ralph E. Powe faculty enhancement award. Congrats!

May 23, 2017 - Our lab received funding from the Minta Martin award for research on in situ TEM and bimetallic nanoparticle catalysts. Congrats!

February 21, 2017 - Our book chapter titled "Liquid Cell Electron Microscopy for the Study of Growth Dynamics of Nanomaterials and Structure of Soft Matter" co-written with collaborator Patricia Abellan at SuperSTEM has been accepted for publication in the upcoming volume of Springer In Situ Nanomaterials Characterization.

February 2, 2017 - Nina Uchida (B.S. candidate) and Shakiba Nikfarjam (M.E. candidate) have joined our lab to research aggregation and stability of biopharmaceuticals. Welcome!

January 24, 2017 - Mei Wang has joined the lab as a Ph.D. student. She will be working on an electrocatalysis project, synthesizing bimetallic nanoparticles in the transmission electron microscope to investigate effects of mesoscale properties on electrocatalytic activity and durability.

January 9, 2017 - Our optical microscopy and spectroscopy setup is complete! The microscope is an automated Zeiss Axioscope optically coupled to a Horiba iHR320 imaging spectrophotometer with high sensitivity Peltier cooled CCD detector, capable of capturing spectra over a range of 300 - 1200 nm. This microscope/spectrometer is capable of dark field optical microscopy, fluorescence microscopy, fluorescence anisotropy, and UV/VIS and fluorescence spectroscopy of single nanoparticles/fluorophores. Many thanks to Gary Rubloff for allowing us to house the NanoCenter's UV/VIS spectrometer in our lab.  We will use this instrument to investigate aggregation of biopharmaceuticals using fluorescence spectroscopy and develop new reconfigurable plasmonic optical materials for national defense applications. The instrument will be available for use through the Maryland NanoCenter this spring.
