Structure-property relationships of layered oxypnictides

Creator:: Muir, Sean W.
Abstract:: Investigating the structure-property relationships of solid state materials can help improve many of the materials we use each day in life. It can also lead to the discovery of materials with interesting and unforeseen properties. In this work the structure property relationships of newly discovered layered oxypnictide phases are presented...

Rapid Microwave Synthesis of the Iron Arsenides NdFeAsO and NdFe₀.₉Co₀.₁AsO

Creator:: Muir, Sean, Rachdi, Omar, and Subramanian, Mas
Abstract:: The future of iron pnictide superconductors in technology is still undecided. While these materials are now known to possess high critical temperatures and critical magnetic fields processing methods for these materials are still in their infancy. Recently we have been investigating possible ways to speed up the synthetic process for...

Rapid Microwave Synthesis of Indium Filled Skutterudites: An energy efficient route to high performance thermoelectric materials

Creator:: Biswas, Krishnendu, Muir, Sean, and Subramanian, Mas A.
Abstract:: Filled skutterudites are promising thermoelectric materials due to reduced thermal conductivity upon inserting a guest atom or 'rattler' into the CoSb₃ structure. By using an indium rattler dimensionless Figure of Merit (ZT) values > 1 at 650 K have been reported. The conventional synthesis of these compounds typically takes several...

Structural and magnetic investigation of Fe3+ and Mg2+ substitution into the trigonal bipyramidal site of InGaCuO4

Creator:: Grajczyk, Rosa, Berthelot, Romain, Muir, Sean, Sleight, A. W., and Subramanian, M. A.
Abstract:: The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were synthesized and characterized through the use of X – ray and neutron diffraction, and DC – magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...

Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

Creator:: Larkey, Nicholas E.
Abstract:: One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...

Innovative Bioanalytical Tools & Methods for Combinatorial Non-Coding RNA Analysis

Creator:: Zhang, Lulu
Abstract:: Recently researchers have discovered that groups of small non-coding RNAs (ncRNAs) play regulatory roles in gene expression and participate in various biological processes. For example, pathogenesis of many diseases, cell cycle regulation, and signaling pathways. Intracellular and live cell imaging of small ncRNA groups will reveal their relative expression levels...

Gold Nanostars: Spectroscopic and Physical Properties

Creator:: Zhou, Lixia
Abstract:: Tethering fluorophores on metal nanoparticles for metal enhanced fluorescence (MEF) has attracted a lot of attention from scientists interested in fluorescence based approaches. MEF has many benefits in fluorescence related techniques, because the analytical signal increases and enables potentially lower detection limits or better sensitivity. Many types of nanoparticles have...

Revealing Ultrafast Dynamics and Functional Basis of Potential Biomedical Tools from Calcium Sensing to Optogenetics

Creator:: Tachibana, Sean R.
Abstract:: Photoactivated biomedical tools like fluorescent biosensors and optogenetic proteins have increased in popularity due to the precision targeting and activation used for in vivo applications. In nature, the initially discovered parent proteins exhibit properties such as fluorescence quantum yield (FQY), fluorescence color, and photoswitching dynamics that are unfavorable in mammalian...

Capturing Molecular Movies of Organic and Organometallic Systems in Solution by Ultrafast Spectroscopy

Creator:: Boulanger, Sean A.
Abstract:: Ultrafast spectroscopy can exploit the structure-function relationship of chemical- and biological-based systems. More specifically, femtosecond stimulated Raman spectroscopy (FSRS) provides ground- and excited-state vibrational information with simultaneously high spectral (spatial) and temporal resolutions. The electronic counterpart, femtosecond transient absorption (fs-TA), complements FSRS data analysis as part of a comprehensive approach...
