LIGAND-ENABLED PLATINUM--CARBON BOND FUNCTIONALIZATION UTILIZING DIOXYGEN AS THE TERMINAL OXIDANT
(2009)The use of organotransition metal complexes for selective functionalization of hydrocarbons is of great importance. Dioxygen is the most practical oxidant for large-scale applications in the petroleum industry. The focus ... -
Ligand-Linked Disorder-to-Order Transitions in Allosteric Communication
(2015)Ligand-linked disorder-to-order transitions are integral to the function of numerous cellular proteins. Furthermore, these transitions can contribute to allosteric regulation, a principal mechanism controlling protein ... -
LIGHT ABSORBING AEROSOLS: CALIBRATION, MEASUREMENTS, AND EMISSIONS FOR NEW YORK CITY
(2021)Light absorbing aerosols such as black carbon (BC) impact weather, climate, and human health. Several instruments have been developed to measure light absorbing aerosols. Filter-based techniques, due to the simplicity of ... -
LIGHT CONTROL OF CHEMICAL SYSTEMS: PHOTOCHEMICAL ELECTRON TRANSFER METHODS FOR RELEASING CALCIUM IONS AND THE PHOTOISOMERIZATION OF ALKENES TO MODULATE RHEOLOGICAL CHANGES.
(2021)Our research combines organic photochemistry with the engineering principles of rheology through the study of photorheological fluids (PR). The two photochemical systems researched show changes in the rheological properties ... -
Light-Driven Chemical Creation of Fluorescent Quantum Defects
(2018)Fluorescent quantum defects are emerging as a new frontier in nanoscience. In semiconducting single-walled carbon nanotubes (SWCNTs) these symmetry-breaking defects are introduced into the sp2 carbon lattice, generating ... -
LINK BETWEEN DYNAMICS AND FUNCTION IN SINGLE AND MULTI-SUBUNIT ENZYMES
(2010)Biopolymers, such as proteins and DNA, are polymers whose three-dimensional conformations dene their biological functions. Current emphasis on structures has greatly advanced our understanding of the functions of ... -
Lipophilic G-Quadruplexes: Structural Studies, Post-Assembly Modification, and Covalent Capture
(2006-08-29)New nanostructures and functional materials are built through the self-assembly of guanosine. Both the size and regiochemistry of these noncovalent structures are controlled. Lipophilic G-quadruplexes are further stabilized ... -
