Tracking the Metal-Centered Triplet in Photoinduced Spin Crossover of Fe(phen)₃²⁺ with Tabletop Femtosecond M‑Edge X‑ray Absorption Near-Edge Structure Spectroscopy

Fe­(II) coordination complexes are promising alternatives to Ru­(II) and Ir­(III) chromophores for photoredox chemistry and solar energy conversion, but rapid deactivation of the initial metal-to-ligand charge transfer (MLCT) state to low-lying (d,d) states limits their performance. Relaxation to a long-lived quintet state is postulated to occur via a metal-centered triplet state, but this mechanism remains controversial. We use femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy to measure the excited-state relaxation of Fe­(phen)32+ and conclusively identify a 3T intermediate that forms in 170 fs and decays to a vibrationally hot 5T2g state in 39 fs. A coherent vibrational wavepacket with a period of 249 fs and damping time of 0.63 ps is observed on the 5T2g surface, and the spectrum of this oscillation serves as a fingerprint for the Fe–N symmetric stretch. The results show that the shape of the M2,3-edge X-ray absorption near-edge structure (XANES) spectrum is sensitive to the electronic structure of the metal center, and the high-spin sensitivity, fast time resolution, and tabletop convenience of XUV transient absorption make it a powerful tool for studying the complex photophysics of transition metal complexes

Subcutaneous and Orbital Adipose Tissues: Intrinsic Differences in Carotenoid Contents and Lipidomic Compositions

The color difference in human subcutaneous fat (SF) and orbital fat (OF) is apparent, but the reasons have been rarely elaborated. We speculate that differences in carotenoid and lipid contents may account for the discrepancy in color. In this study, the intrinsic differences in SF and OF were analyzed using ultrahigh-performance liquid chromatography coupled with Q-Exactive liquid chromatography mass spectrometry/mass spectrometry (UPLC-QE Plus LC–MS/MS). Lipid profiling was performed in an independent batch. The morphology between orbital septum and SF differed statistically in the size of adipocytes and the distribution area of adipocytes. We compared carotenoid contents between two groups (seven samples) and found that lutein was more abundant in SF than that in OF with a p-value of 0.0409, suggesting that lutein could be mainly responsible for the yellow color of adipose tissue. Lipidomic results proved that SF and OF were well differentiated. Totally, 402 lipid features were detected, with 349 features in the positive ion mode and 53 features in the negative ion mode. Features (99.9%) in the positive ion mode and features (98.7%) in the negative ion mode well described various separation patterns in principal component analysis. Thirty-two features selected by variable importance in projection might account for the diversity of compounds in SF and OF. In conclusion, SF and OF differed from each other in carotenoids and lipidome. It is helpful to study the metabolism process of lipid droplets in adipocytes

Table_3_Identification of Key Gene Networks Controlling Soluble Sugar and Organic Acid Metabolism During Oriental Melon Fruit Development by Integrated Analysis of Metabolic and Transcriptomic Analyses.XLSX

Oriental melon (Cucumis melo var. acidulus) is one of the most economically important fruit crops worldwide. To elucidate the molecular basis related to soluble sugar and organic acid metabolism in the fruits of two oriental melon cultivars with different sweetness, we performed integrated metabolomic and transcriptomic analyses of the fruits of ‘Tianbao’ (A) with high sweetness and ‘Xiaocuigua’ (B) with low sweetness at different ripening stages. The high accumulation of sucrose, D-glucose, D-(+)-raffinose, and the relatively lower citric acid and malic acid might contribute to the sweet taste of A. By screening the differentially expressed genes (DEGs) and correlation analysis of the DEGs and differentially accumulated metabolites, we deduced that the B cultivar might promote the conversion of glucose and fructose into intermediate compounds for downstream processes such as glycolysis. The tricarboxylic acid (TCA) cycle might also be enhanced compared to A, thus resulting in the differential accumulation of soluble sugars and organic acids, ultimately causing the taste difference between the two oriental melon cultivars. Our finding provides important information for further exploring the metabolic mechanisms of soluble sugars and organic acids in oriental melon.</p

Sulfur-Doped MXene-Based Nanocomposites for Efficient Electromagnetic Wave Absorbers via Polarization and Magnetization

Ti3C2Tx (MXene) materials with multilayered structures have been widely investigated as promising absorption materials. However, the electromagnetic wave absorption performance of a single Ti3C2Tx MXene has always been limited by interface mismatches due to high reflectivity. In this work, sulfur-doped MXene-based nanocomposites were constructed by a mild doping and calcination method and performance was regulated by manipulating chemical composition, loading ratio, electromagnetic parameters, or impedance matching. Here, sulfur-doped MXene and titanium dioxide produced via high-temperature calcination (S-MXene (TiO2)) provided abundant defects and functional groups, resulting in dipole polarization relaxation. The introduction of Ag improved the electrical conductivity, and the CoNi alloy could enhance the magnetic loss and improve impedance matching. The electromagnetic wave absorption ability was enhanced thanks to the combined effects of suitable conductivity, dipole polarization, interface polarization, and magnetic loss. The S-MXene (TiO2)/Ag/CoNi nanocomposites exhibited a high reflection loss of −63.1 dB at a thickness of 2.1 mm and a wide effective absorption bandwidth of 5.2 GHz at a thickness of 2.0 mm. Moreover, by adjusting the mass ratio of nanocomposites’ components, the minimum reflection loss value was up to −80.9 dB at only 1.5 mm. This mechanism of increasing material loss through doping is of great significance for improving the electromagnetic wave absorption of MXene-based nanocomposites

Self-Adhesive Dry Ionic Conductors Based on Supramolecular Deep Eutectic Polymers

Ionic conductors have promising applications in the field of flexible electronics, but they usually suffer from weak bonding to substrates (<0.3 MPa), leading to large interfacial impedances or detachment under repeated deformation. Here, a supramolecular deep eutectic polymer synthesized by in situ photopolymerization of a polymerizable deep eutectic solvent monomer is proposed as a self-adhesive dry ionic conductor (SADIC). The SADICs obtained are rich in dynamic hydrogen bonding and ions, which can instantly form various interfacial interactions and firmly adhere to substrates and maintain good mechanical robustness. Notably, the maximum adhesion strength is up to ∼3.5 MPa (on indium tin oxide (ITO) glass). Furthermore, the SADICs also show other comprehensive properties such as high transparency, tunable stretchability, favorable conductivity, and excellent mechanical and electrical self-healing capabilities. As a demonstration, the SADIC can be used as a durably self-adhesive ionic skin for volume change and deformation monitoring. These findings provide a promising strategy for improving device integration and enhancing the performance of flexible electronics

Selective Hydrogenolysis of 5‑Hydroxymethylfurfural into 2,5-Dimethylfuran under Mild Conditions Using Pd/MOF-808

2,5-Dimethylfuran (DMF) is an important candidate for liquid fuels, which can be produced from biomass-derived 5-hydroxymethylfurfural (5-HMF). Efficient catalysts for selective hydrogenolysis of HMF to DMF under mild conditions without any additives are highly desired. Herein, we designed and prepared a Zr-based metal–organic framework (MOF-808) supported Pd catalyst (Pd/MOF-808), which can efficiently catalyze the hydrogenolysis of HMF to DMF with a yield of 99% under 100 °C without any additives. In addition, the Pd/MOF-808 catalyst also showed good reusability, with the capability of being used five times without loss of activity
