Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.

Glycolytic reprograming in Salmonella counters NOX2-mediated dissipation of ΔpH. [PDF]

open access: yes, 2020
The microbial adaptations to the respiratory burst remain poorly understood, and establishing how the NADPH oxidase (NOX2) kills microbes has proven elusive. Here we demonstrate that NOX2 collapses the ΔpH of intracellular Salmonella Typhimurium.

Obtaining Curvature‐Based HLD Parameters for Single Ionic Surfactants via Small Angle X‐Ray Scattering (SAXS)

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT The hydrophilic–lipophilic difference (HLD) for ionic surfactant microemulsions (μEs) can be interpreted as the curvature normalized by the tail length parameter (L), if it is corrected by a factor “bi”, bi·HLD = HLDcurv = HLDbi = bi·ln(S) – kbi·EACN + Ccbi, with bi and kbi representing the curvature sensitivity to changes in salinity (S, g ...

Evaluation of Inhibitive Action of Sodium Benzoate on Corrosion Behaviour of AA6063 in Seawater

open access: yesInternational Journal of Technology, 2014
Corrosion is a fundamental process which plays an important role in economics and safety. Apparently, corrosion cannot be avoided, but its severity can be prevented. Inhibitors have always been considered to be the first line of defense against corrosion.

Absolute Quantification of Brain Deuterium Metabolic Imaging in Healthy Volunteers and Glioblastoma Patients at 7T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose We present a method for absolute quantification of deuterated metabolites in vivo at 7T. We describe acquisition protocols and an analysis pipeline compatible with 7T Terra MRIs. We apply them using a 2H/1H receive array in healthy volunteers and glioblastoma patients.

Schiff based derived homogeneous catalysts for ring‐opening terpolymerization

open access: yesPolymer International, EarlyView.
One‐pot synthesis of degradable terpolymers from l‐lactide, propylene oxide and CO₂ using diverse catalysts is described, revealing structure–property relationships for tailored applications in sustainable materials. Abstract In this study, we synthesized and evaluated a series of Schiff base cobalt catalysts for the terpolymerization of propylene ...

Food additives and children's behaviour: evidence based policy at the margins of certainty

open access: yes, 2009
The possible effects of food additives (specifically artificial colours) have been debated for over 30 years. The evidence accumulated suggests that for some children with attention deficit hyperactivity disorder (ADHD) food colours exacerbate their ...
