Dialumane 1 reacts with tBuNC to produce a reductive dimerization adduct [LAl(tBuN[double bond, length as m-dash]C-C[double bond, length as m-dash]NtBu)AlL] (2). In the presence of Na, 1 can promote linear- and cyclo-trimerization of isocyanides, affording products [Na][LAl{(tBuNC)3}AlL] (3 and 4) and [Na][LAl{(tBuNC)3}Al(C[triple bond, length as m-dash]N)L] (5), the latter of which features a unique aromatic tri(tert-butylimino)deltate dianion [C3N3(tBu)3]2-.

This review discusses the chemical properties, synthesis and detection, and biological functions of a molecular group of cis-2-unsaturated fatty acids, containing fatty acid carbon chains of various lengths and cis double-bond configurations, known as the diffusible signaling factor family (DSFF). Early postulation of the conserved nature of the DSFF among Gram-negative bacteria have now been challenged by the latest evidences that unraveled their presence in a various other distinct microorganisms. Over the last decade, a significant depth and breadth of understanding has been made on the multifaceted functions of DSFFs among bacteria, and their interactions with evolutionarily divergent fungi, plants insects and small animals.

The synthesis, structures and magnetic properties of an η5-silole complex and an η5-stannole complex of erbium are reported. The sandwich complex anions [(η5-CpSi)Er(η8-COT)]- and [(η5-CpSn)Er(η8-COT)]-, where CpSi is [SiC4-2,5-(SiMe3)2-3,4-Ph2]2- (1Si), CpSn is [SnC4-2,5-(SiMe3)2-3,4-Me2]2- (1Sn) and COT = cyclo-octatetraenyl, were obtained as their [K(2.2.

Synergistic effect of scattered rare metals on Pt/CeO for propane oxidative dehydrogenation with CO.

RSC Adv

The oxidative dehydrogenation of propane with CO (CO-ODP) is a green industrial process for producing propene. Cerium oxide-supported platinum-based (Pt/CeO) catalysts exhibit remarkable reactivity toward propane and CO due to the unique delicate balance of C-H and C[double bond, length as m-dash]O bond activation. However, the simultaneous activation and cleavage of C-H, C-C, and C-O bonds on Pt/CeO-based catalysts may substantially impede the selective activation of C-H bonds during the CO-ODP process.

Carbon Doping in Small Lithium Clusters: Structural, Energetic, and Electronic Properties from Quantum Monte Carlo Calculations.

ACS Omega

Instituto de Física, Universidade Federal de Goiás, Goiânia, Goiás 74001-970, Brazil.

We investigate the energetic and structural properties of small lithium clusters doped with a carbon atom using a combination of computational methods, including density functional theory (DFT), diffusion quantum Monte Carlo (DMC), and the Hartree-Fock (HF) approximation. We calculate the lowest energy structures, total ground-state energies, electron populations, binding energies, and dissociation energies as a function of cluster size. Our results show that carbon doping significantly enhances the stability of lithium clusters, increasing the magnitude of the binding energy by 0.

This research focuses on the selective detection of Hg2+ ions using hybrid nanosensors composed of rhodamine building blocks linked to polyamine units of varying chain lengths to produce Rho1-Rho4, which were subsequently conjugated with thioctic acid (RT1-RT4) and attached to the surface of gold nanoparticles to create hybrid nanosensors (GRT1-GRT4) designed for detecting heavy metals. The chemical structures, purity, morphology, and chemical composition were characterized through XRD, NMR, TEM, ATR-FTIR, and mass spectrometry. These hybrid nanosensors demonstrated excellent selectivity and sensitivity in colorimetric and fluorescence responses towards Hg2+, outperforming other metal ions.
