Reducing Toxic Hexavalent Chromium for Clean Water

Reducing Toxic Hexavalent Chromium in Water

Highly toxic Cr(VI) can be reduced to benign Cr(III) in water on unmodified and inexpensive carbon electrodes. The slow step over a wide range of pH is identified, which will help develop new energy-efficient water purification technologies.

Carbon Nanohoops

Carbon Nanohoops Image

Carbon nanohoops are conjugated macrocycles with radially-arranged aromatic groups. Here, a carbon nanohoop was prepared in high yields from a non-symmetric building block using alkyne metathesis. This nanohoop exhibited blue fluorescence with high quantum yields.

Quorum Sensing

Quorum Sensing image

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.

DEFENSINS IN MEMBRANES

Defensins in membranes image

High-resolution ¹³C, ³¹P and ¹H Solid-State NMR and 5-µs MD modeling are integrated to determine the site-specific structure of human defensins in lipid bilayers and how these peptides reshape lipid vesicles.

PHOTOCHEMICAL OXIDATION MASS SPECTROMETRY

photochemical oxidation graphical abstract

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

molecular structure of electrolytes

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.

FRONTAL POLYMERIZATION

Frontal Polumerization affecting surface

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 structure of Cationic Cobalt(II)

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.

Photopolymerization of Monomer-Containing Deep Eutectic Solvents

The kinetics of photopolymerization in deep eutectic solvents (DESs) is investigated through RT‐FTIR. The

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.
