Article Abstract
Reduction of [CMe(SiMeBu)]ScI with KC generates the first example of a neutral, linear metallocene of scandium analogous to ferrocene, namely [CMe(SiMeBu)]Sc. X-ray diffraction studies, spectroscopic analyses, and DFT calculations are consistent with a Sc(II) complex. [CMe(SiMeBu)]Sc reacts reversibly with N to provide the end-on (N═N) complex {[CMe(SiMeBu)]Sc}(μ-η:η-N) and gives a rare example of a crystallographically characterizable Sc(III) terminal hydroxide, namely [CMe(SiMeBu)]Sc(OH), as a hydrolysis product. The analogous linear Ca(II) metallocene [CMe(SiMeBu)]Ca was synthesized and characterized for comparison.

The determination of homocysteine (HCys) has garnered significant interest within the biomedical community in recent years, as it serves as a key biomarker for a variety of diseases. Disruptions in HCys metabolism can lead to elevated blood levels of HCys, which are associated with cardiovascular diseases, Parkinson's disease, and etc. Therefore, the sensitive analysis of HCys levels in biological samples is crucial.

Glycated hemoglobin (HbA1c) is an important biomarker applied for the diagnosis, evaluation, and management of diabetes; therefore, its accurate determination is crucial. In this study, an innovative nanoplatform was developed, integrating carbon nanotubes (CNTs) with enhanced hydrophilicity achieved through cyclodextrin (CD) functionalization, and combined with gold nanoparticles (AuNPs) electrochemically deposited onto a screen-printed carbon electrode. The nanomaterials significantly improved the analytical performance of the sensor due to their increased surface area and high electrical conductivity.

Dual-mode lateral flow assays (LFAs) have gained significant attention, yet existing systems predominantly combine optical modalities, leaving hybrid colorimetric-electrochemical configurations underexplored despite their potential to achieve diagnostic synergy and minimize interference. Here, we present a universally compatible, low-cost lateral flow platform leveraging dual-signal nanohybrids for synchronized colorimetric-electrochemical detection. A hierarchically hollow Cu/Zn-metal-organic framework (MOF) bearing carboxyl functional groups was rationally designed to anchor gold nanoparticles (AuNPs) in situ for colorimetric signaling, followed by covalent immobilization of aminoferrocene to establish electrochemical signaling.

Mixed-ligand metallocene complexes serve as crucial precursors in organometallic actinide chemistry. However, a systematic and comprehensive understanding of how ligands influence the electronic structures and physicochemical properties of these compounds remains scarce. Hence, relativistic density functional theory (DFT) and ab initio wave function theory (WFT) calculations were carried out to elucidate the impact of auxiliary ligands on the bonding, redox properties, and electronic absorption spectra of uranium(IV) metallocene complexes, Cp*U(NR)X (Cp* = CMe, R = SiMe, and X = F, Cl, Br, I, NCO, and OEt).
