Title: Structure-Property Relationships in Porous and Non-Porous Coordination Polymers for Catalytic, Battery, and Sensing Applications

Abstract: Metal–Organic Frameworks (MOFs) standout amongst coordination polymers due to their porous structures and facile tunability. Porous coordination polymers can be designed and utilized for applications such as carbon capture, energy storage, and…

Title: Size-dependent surface structure of COF-embedded UO2 nanoparticles

Abstract: Characterization of actinide oxides at the nanoscale presents unique challenges due to their radioactivity, high surface area, and inherent diffraction broadening due to small grain size. Extended x-ray absorption spectroscopy (EXAFS) is an analytical method to investigate atomic-scale structural properties that…

Title: A Review of Tubulin Aggregation Induced by Covalent Isopeptide Cross-linking Following Chloropyrifos Oxon Exposure

Title: Utilizing Fluorescent Dyes to Manipulate Reactivity in Molecular Complexes
Abstract: Main group Lewis acids can promote some of the same chemical transformations that can be promoted with metal complexes, but their inability to undergo redox chemistry limits their applicability as an alternative to metal-containing complexes in chemical and catalytic transformations.

Title: Spectroscopic Signatures of UCl3 in LiCl/KCl eutectic via AIMD simulations
Abstract: Characterization of chloride molten salts with high f-element loading remains limited in literature despite relevance to nonproliferation and online monitoring of molten salt reactors and pyroprocessing separation schemes. Coupled spectroscopic and computational investigations provide certain benefits, as experimental information can validate simulation, while simulations can provide atomistic resolution.

Investigating Catalytic Ester Hydrolysis Using Ruthenium Complexes Supported by PNNNP Pincer Ligands
Esters are an important class of compounds due to their extensive uses in everyday life.

Thiol redox proteome involves a series of post-translational modifications of proteins, mainly in cysteine. These modifications are known to regulate protein function and alter the thiol oxidative and reductive states of cysteine residues.

Materials with tunable properties are needed to address issues, such as the capture of greenhouse gases, the detection of hazardous chemicals, and the storage of energy. Coordination polymers are a type of hybrid polymeric crystalline material formed from the connection of organic ligands and metal ions or clusters through coordination bonds. The wide array of building blocks that can be used enables coordination polymers to be rationally designed and tuned to possess specific properties.

Electrochemical Oxidation of Formate and Reduction of CO2 into Formate and C2 Compound

This work presents a detailed investigation of the influence of solid supports on the axial ligand binding properties of cobalt porphyrins. Metal porphyrins and other tetrapyrrole molecules form well-ordered, self-assembled monolayers on solid supports and because of unsaturated character of the metal atom within the macrocycle may form five and six coordinate complexes with axial ligands. Porphyrin chemistry is well understood in the solution environment; however, this knowledge does not always translate to accurate predictions of the behavior of porphyrins confined to a surface.

Title: Structure and Reactivity of Iron Oxides: The Usefulness of Mössbauer Spectroscopy

Abstract: Among the different iron oxides present in the environment, mixed FeII-FeIII compounds play a specific role due to their high chemical reactivity. In…

Mercaptoethane sulfonate or coenzyme M (CoM) is the smallest known organic cofactor, and is most commonly associated with the methane forming step in all methanogenic archaea. It has also been found in a small number of bacteria capable of the metabolism of small organics. Although many of the steps for CoM biosynthesis in methanogenic archaea have been elucidated, a complete pathway for the biosynthesis of CoM in archaea or bacteria has not been reported. Here we present the complete CoM biosynthesis pathway in bacteria, revealing distinct chemical steps relative to CoM biosynthesis in methanogenic archaea.

A comprehensive investigation on the formation dynamics and energetics of adlayer formation at the at the solution/solid interface has been performed using scanning tunneling microscopy (STM) with a custom solution flow cell design that offers new insight into the self-assembly process.

Controlling the organization of nanoparticles on a surface can open the door to increased control over the properties of a nanomaterial.

Title: Investigation of the Unique Electronic Structures of Cp2U(NR)2 and Cp2U(NR)(O) Complexes

Abstract: Uranium has a significant impact on the environment because of its radioactivity and the fact that its most stable form, uranyl ([UO2] 2+), has high mobility in groundwaters and soil. The uranyl cation features two mutually trans…

Porous organic polymers (POPs) both amorphous and crystalline represent an emerging class of nanoporous materials, and they feature robust covalent framework structures with high water and chemical stability.

β-Galactosidase (β-Gal) is an important biomarker for metastatic ovarian cancers, with β-Gal being overexpressed in cancer cells compared to healthy ovarian tissue. Fluorescent imaging of in vivo β-Gal activity has become an accepted method for diagnostic screening and evaluation of cancers.

Mass spectrometers have historically been revered for their accuracy and precision. Further techniques, such as MS/MS where mass analysis is performed more than once on an analyte, have been able to add an additional level of specificity to identification of a wide variety of analytes. However, the large size and high cost of mass spectrometers creates obstacles for accessibility and widespread application of these instruments.

Title: Electrochemical Quantitative Analysis of Hydrogen Sorption / Desorption in Palladium During Acidic Electrolysis

Abstract: Recent studies were completed on palladium catalysts that explored hydrogen storage applications during electrolysis. 4.0 to 5.0 mg samples of palladium were tested from 200 to -200 millivolts at 10 mV per second scans in…
