Influence of Reactive Additives on the Polyoxometalate‐Catalyzed Oxidation of Xylose to Formic Acid

open access: yesChemCatChem, EarlyView.
In this study, the influence of various reactive additives on the kinetics of xylose oxidation to FA using the HPA‐5 (H8PV5Mo7O40) POM‐catalyst has been investigated both in aqueous as well as in aqueous‐methanolic solution. Abstract Chemo‐catalytic biomass valorisation using polyoxometalate (POM) catalysts is a promising strategy for green and ...

Low‐Micromolar Quantification of Fluorinated Analytes Using Hyperpolarized 19F Benchtop Nuclear Magnetic Resonance

open access: yesChemistry–Methods, EarlyView.
Limits of detection and quantification of fluorinated analytes by 19F benchtop (1 T) NMR spectroscopy in the high nanomolar to low micromolar range are achieved using signal amplification by reversible exchange (SABRE) combined with the multiplet‐refocusing technique, SHARPER (Sensitive, Homogeneous, And Resolved PEaks in Real time).

The CSI Effect and Its Potential Impact on Juror Decisions [PDF]

open access: yes, 2015
The “CSI Effect” was first described in the media as a phenomenon resulting from viewing forensic and crime based television shows. This effect influences jurors to have unrealistic expectations of forensic science during a criminal trial and affect ...

Bridging THC Knowledge Gaps for Safer Roads: A Call for Action

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The rising cases of cannabis‐impaired driving present a looming public safety concern that's currently addressed through varying state regulations. However, these regulations are yet validated and lack scientific robustness. One of the roadblocking factors is our insufficient understanding of THC's pharmacokinetics (PK) and pharmacodynamics (PD) due to

Fluorescent and Chemiluminescent Dyes with Aryl Phthalimide and Aryl Luminol Chromophores

open access: yesChemPhotoChem, EarlyView.
A series of photo‐active phthalimides and luminols is prepared by an arylation method from a key precursor. Significant stereoelectronic correlation of the aromatic substituents with the photophysical properties is documented. A new arylated luminol derivative shows a more than three times higher ΦCL than the parent luminol.
