Quorum Sensing is a biological phenomenon of cellular communication which plays a role in biofilm development or even bacteria colony growth. We emulate this communication by using an analog of urease encapsulated beads subjected to a urea solution.
PHOTOCHEMICAL OXIDATION MASS SPECTROMETRY
A193 nm laser is directed at the electrospray source of a mass spectrometer that contains hydrogen peroxide and a protein. The photogenerated radicals oxidize the protein, enabling ultrafast characterization of its structure.
ELECTROLYTES IN MOTION
The molecular structure and dynamics of electrolytes is important in science and engineering due to their use in electrochemical storage. Time resolved infrared spectroscopic methods are currently the best tools for investigating the electrolytes at the microscopic level, but understanding these liquid systems remains very challenging.
DIVERSITY IN STEM
An evaluation study with a mixed methods approach evaluating program impacts and outcomes of a minority training program over a period of 14 years. Results indicate which strategies were most effective in promoting interest and matriculation into graduate programs among underrepresented groups in STEM.
STABILIZATION OF ELECTROCATALYSTS
Fighting deactivation: Classical and emerging strategies for efficient stabilization
of molecular electrocatalysts.
The capacity of frontal polymerization as a coating strategy for wood substrates was studied. Results indicate resin viscosity and film thickness critically affect the qualitative and quantitative propagation of the thermal front resulting in the formation of the coating
Cationic Cobalt(II) Bisphosphine Hydroformylation Catalyst
Hydroformylation is one of the highest-volume homogeneously catalyzed industrial processes today. One segment of the market deals with unreactive alkenes that require the most active cobalt or rhodium-based catalysts that need high pressures (> 200 atm) to prevent decomposition of the catalysts. A new class of cationic cobalt bisphosphine hydroformylation catalysts exhibit exceptional activity under medium pressure conditions and remarkable stability with respect to cobalt-induced phosphine degradation reactions or decomposition to cobalt metal.
Research and Training Program
A multiple case study involving participants of an MRT program who completed a BSc degree but did not subsequently matriculate into a doctoral program. Results identify perceived barriers deterring continuation into doctoral degree programs among former MRT participants.
Photopolymerization of Monomer-Containing Deep Eutectic Solvents
The kinetics of photopolymerization in deep eutectic solvents (DESs) is investigated through RT‐FTIR. The systems of this study are choline chloride DESs made of acrylic acid and methacrylic acid (DES monomers) and a nonreactive analog isobutyric acid. Analysis of the evolution of conversion indicates dramatic increase in polymerization rate when comparing the polymerization of the DES monomers to pure monomer polymerization.
A siloxide podand ligand is used to tease out structure-reactivity relationships in
alkyne metathesis. It also affords a very rare (and dynamic!) metallatetrahedrane.
