Chemical Nanolithography and Single Molecule Optical Imaging With Metal -Coated Probes
… micronewtons, induced reactions of the terminal organic functional groups. These written features, labeled with fluorescent dyes, biomolecules, and nanoparticles, were imaged with confocal microscopy and atomic force microscopy. The use of metal-coated AFM tips in apertureless near-field scanning …

Developing near- and mid-infrared spectroscopy analysis methods for rapid assessment of soil quality in Illinois
… conventional-tillage, conservation-tillage or organic practices and so were expected to vary in SQ. Partial Least Squares Regression (PLSR) and Random Forest (RF) algorithms were used to predict SQ indicators, including soil organic carbon (SOC), total N (TN), soil C and N ratio (C: N), soil …

Significance of pH and pCl in heavy metal ion reactions and mercury (II) adsorption by soil materials
… on clays, and Hg(II) interactions with organic functional groups. Occurrence of and competition between Hg(II) hydroxy and chloride complexes is important at all pH and chloride concentrations encountered in natural waters. Hydrolysis of Pb(II), Zn(II), and Cd(II) increases markedly …

Synthesis of diene ligands with H-bonding capabilities for bioimaging applications
… at about 2000 cm–1 where absorptions of most of organic functional groups are absent. Their narrow vibrational stretching modes provide information about the iron complex and its environment. Scheme A In the first project, novel tricarbonyliron complexes were synthesised by N-acylation with …

Functional Metal Phosphonates
… in this dissertation was the incorporation of functionality into metal phosphonates. This was done in one of several ways. The first involved using phosphonate ligands that had covalently attached organic functional groups. In some cases, these ligands undergo reactions during the solvothermal …

Biologically Controlled Mineralization and Demineralization of Amorphous Silica
… The extent, and mechanism through which specific organic moieties work individually or in concert to direct mineral formation at biological interfaces is a central concern of modern biomineralization research. Chapter two addresses this forefront issue for silica mineralizing systems, and reports …

Using molecule-surface interactions for improved photoelectrochemical device performance and modeling
The attachment of organic molecules known as functional groups to the surfaces of metals and semiconductors is called surface functionalization. It is a popular approach for tuning the underlying material’s properties such as its surface chemistry, band gap, and chemical stability. Surface …
