Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Exploration of the Interconversion of Uranium Anilido and Imido Species

ChemistryEurope, EarlyView.
Exploring the reactivity of the trivalent U(NHDIPP)5K2(THF)4 (1) leads to the formation of uranium imido complexes. Treating 1 with 18c6 causes spontaneous oxidation and the formation of [U(NDIPP)(NHDIPP)4][K(18c6)(THF)]2 (2). Oxidation of 1 or 2 results in the formation of U(NDIPP)2(NHDIPP)2 (3).

Aluminum versus Gallium: Differences in Bis(bis(trimethylsilyl)methyl) Element Halides, Hydrides, and Oxygen‐Bridged E/P Frustrated Lewis Pairs

ChemistryEurope, EarlyView.
Reacting Bis2GaBr (Bis = CH(SiMe3)2) with Bis2AlH selectively yields Bis2GaH, a monomeric hydride in solution, characterized by diffusion ordered spectroscopy NMR, infrared spectroscopy and indirectly via hydrogallation. A one‐pot route enables frustrated Lewis pairs Bis2EOPtBu2 (E = Al, Ga), with the gallium analog splitting H2 and showing a dynamic ...

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

Conformational Trajectory of the Molecular Chameleon Grazoprevir from Formulation to Target‐Bound

Chemistry – A European Journal, EarlyView.
ABSTRACT Macrocycles represent a promising class of beyond‐rule‐of‐5 (bRo5) therapeutics, capable of targeting proteins traditionally considered undruggable by conventional small molecules. Macrocycles exhibit intrinsic flexibility and often display a “chameleon‐like” ability to adapt to their environment, thereby enhancing their oral bioavailability ...
