Aggregation Effect of Near-Infrared Boron Difluoride Formazanate Dyes
21 Aug 2022 | | Contributor(s):: Jessica Robicheaux, Rice University
How are near-infrared (NIR) dyes used for their enhanced capability in fluorescence detection and imaging, tissue penetration depth and low background with minimal fluorescence from surrounding tissues? This research focuses on Aggregation Induced Emission (AIE) in order to utilize boron...
Charged-Particle Interaction Analysis
07 Jan 2022 | | Contributor(s):: Atilla Ozgur Cakmak, NACK Network
Scanning Electron Microscopy (SEM) has traditionally been the most frequently used micro-/nano- characterization technique to overcome the optical losses coming from lenses. In this talk we are going to begin by discussing the fundamental blocks of an SEM starting from the electron beam emission....

Digital Materials Design
11 May 2020 | | Contributor(s):: Mark Knackstedt
The key to DMD is access to efficient facilities and tools to characterisematerial structure and function at multiple scales (from nanometers to structural sizes), in multiple states (relaxed vs under compression, before/after reaction or dissolution) and with multiple probes (multiple x-ray...
Resistively-Detected NMR and Nuclear Resonance Imaging
07 May 2020 | | Contributor(s):: Yoshiro Hirayama
NMR provides us versatile tool to physical, chemical, biological, and medical characterizations. However, conventional NMR suffers low sensitivity and cannot be applied to semiconductor quantum systems, such as single quantum well or wire. To overcome these difficulties,...

Golden Opportunities: Gold Nanoparticles for Biomedical Applications
14 Jan 2020 | | Contributor(s):: Catherine J. Murphy
In this talk I will discuss how these nanoparticles are prepared, how their surface chemistry can be tuned, how apparent cytotoxicity can be traced back to reagents in the synthesis rather than the particles per se, how protein orientation can be controlled on their surfaces, how cells respond...
Biological 3D Structures by Cryo-EM: Challenges in Computations and Instruments
23 Oct 2019 | | Contributor(s):: Wen Jiang
Single particle cryo-EM is revolutionizing structural biology. Many structures of viruses and protein complexes have been determined to 2-4 Å resolutions. While stable structures that can be expressed/purified in large quantities can be solved routinely, the dynamic compositions and...
