Electrochemistry and spectroelectrochemistry of iron porphyrins in the presence of nitrite [PDF]

, 2001
The reaction of nitrite with ferric and ferrous porphyrins was examined using visible, infrared and NMR spectroscopy. Solutions of either ferric or ferrous porphyrin were stable in the presence of nitrite, with only complexation reactions being observed.

Arginase from kiwifruit: properties and seasonal variation [PDF]

, 1988
The in vitro activity of arginase (EC 3.5.3.1) was investigated in youngest-mature leaves and roots (1-3 mm diameter) of kiwifruit vines (Actinidia deliciosa var. deliciosa) during an annual growth cycle, and enzyme from root material partially purified.

Synthesis and Electrolyte Study of Lithium Bis(perfluorinated pinacolato)Borate for Lithium‐Ion Batteries

Chemistry – A European Journal, EarlyView.
This work showcases the synthesis of lithium bis(perfluorinated pinacolato)borate and investigates its application as an electrolyte salt for lithium‐ion batteries. The synthesized salts give improved air and thermal stability compared to conventionally used lithium hexafluorophosphate.

Study of mechanism which causes film formation on mercury surfaces [PDF]

The mechanism by which small quantities of dissolved tin, sodium, and lithium lower the rate of evaporation of mercury in vacuum is determined. An apparatus was built in which dilute amalgams could be prepared and studied in an oxygen-free environment ...

Class I Gap-formation in Highly-viscous Glass-ionomer Restorations: Delayed vs Immediate Polishing [PDF]

, 2008
This in vitro study evaluated the effects of delayed versus immediate polishing to permit maturation of interfacial gap-formation around highly viscous conventional glass-ionomer cement (HV-GIC) in Class I restorations, together with determining the ...

Mononuclear Molybdenum and Tungsten Phosphine Complexes for Catalytic Ammonia Synthesis: Development of the pentaPod Concept

ChemPhysChem, EarlyView.
The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,

Ferrocene and Ferrocenium Modified Clays and Their Styrene and EVA Composites [PDF]

, 2007
In this work, ferrocene- and ferrocenium-containing salts were employed to modify montmorillonite. X-ray measurements show an increase in the interlayer spacing upon clay modification, which means that the larger and more organophilic cations were ...

Transformations of Group 7 Carbonyl Complexes: Possible Intermediates in a Homogeneous Syngas Conversion Scheme [PDF]

, 2009
A variety of C−H and C−C bond forming reactions of group 7 carbonyl complexes have been studied as potential steps in a homogeneously catalyzed conversion of syngas to C_(2+) compounds.

A Mucoadhesive Hydrogel for Precise Resveratrol Delivery in the Management of Inflammatory Bowel Disease

Food Frontiers, EarlyView.
CMTR‐Gel targeting to the inflamed mucosa by electrostatic interactions. ABSTRACT Natural drug‐food homology compounds have vast therapeutic potential, particularly for inflammatory bowel disease (IBD), but their poor water solubility, instability, and limited mucosal availability hinder their clinical translation.

An Eco‐Friendly and Sensitive Microwave‐Aided Spectrofluorophotometric Characterization of Mirabegron‐Loaded Nanocarriers by Amalgamation of Design of Experiments and White Analytical Chemistry

Luminescence
ABSTRACTMirabegron, a drug for treatment of overactive bladder, has low water solubility and bioavailability. Researchers used quality by design to develop and characterize second‐generation lipid nanocarriers for mirabegron, aiming to provide spatially and temporally sustained drug release. Numerous analytical methodologies for assessing mirabegron in
