A Cost‐Effective Hybrid Method For Homogeneous Matrix Coating in Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry Imaging Using Simultaneous Spin and Spray Deposition

Analysis &Sensing, EarlyView.
This study introduces an in‐house spin coater for matrix‐assisted laser desorption/ionization mass spectrometry imaging, providing homogeneous matrix deposition via simultaneous spray and spin. The approach yields reproducible signals and clear metabolite distributions in complex tissues.

Noninvasive Glucose Detection with Biodegradable Electrodes from Rice Starch Functionalized with a Carbon Quantum Dot/Nickel Oxide Nanocomposite

Analysis &Sensing, EarlyView.
The graphical abstract shows an eco‐friendly approach to fabricating a biodegradable electrochemical sensor. Carbon quantum dot/nickel oxide (CQD/NiO) nanocomposites are synthesized using Aloe arborescens leaf extract, which served as a natural reducing and stabilizing agent.

Chimera X Interface to Enhance Understanding in Biochemistry and Immunology

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Proteins are essential in biological systems, acting in transport, catalysis, and immune defense processes. However, these biomolecules' structural and functional complexity makes teaching and understanding these topics challenging. To address this difficulty, this study aimed to develop tutorials that facilitate learning and teaching about ...

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.
