Reaction conditions were systematically investigated through solvent optimization, mixture design modeling, and kinetic studies. Moreover, the ionization and fragmentation behavior of aPB-derivatized TGs was comprehensively investigated, revealing distinct fragmentation pathways associated with charge localization effects in neutral lipids. Application to complex matrices demonstrated the feasibility of the approach, providing direct access to TG regioisomer distributions in human plasma and vegetable seed oils. Overall, the proposed strategy enables untargeted and double-bond-resolved annotation of TGs in complex matrices while maintaining straightforward sample preparation and compatibility with routine lipidomics workflows.

This approach combines effective matrix removal in silicate rock samples through the formation of insoluble fluorides during microwave-assisted digestion and the volatilization of silicon as SiF4 with the capability of ICP-MS to quantify target isotopes at very low signal intensities (10-100 cps) using optimized acquisition parameters. Moreover, the ability to perform ICP-MS measurements at such low signal intensities also enables matrix reduction in other sample types, such as ores, through simple dilution while maintaining sufficient analytical sensitivity. Since proposed strategy employs fast microwave dissolution of PGEs together with their reliable and accurate determination, without the need for complex and time-consuming matrix-separation procedures such as ion-exchange chromatography or tellurium co-precipitation, the analytical workflow is significantly simplified, and the overall analysis time is reduced several-fold compared with conventional methods. At the same time, detection and quantitation limits are below 0.1 and 0.5 ng/g, respectively, for all analytes except Pd, for which the corresponding limits are 0.18 and 0.9 ng/g, enabling the determination of PGEs in variety rock types.

Unlike conventional metal-oxide gas sensors operating at elevated temperatures, the formation of a p-n heterojunction between p-type Ag2O and n-type ZnO facilitates efficient charge separation and significantly lowers the activation energy for acetone oxidation, enabling enhanced sensing at ambient conditions. The structural and morphological properties were characterized by X-ray diffraction, FESEM, XPS, and FTIR. The sensing performance was achieved by coating the modified fiber cladding with ZnO@Ag2O, where evanescent-field interaction and adsorption-induced optical property changes govern the sensing mechanism, as validated by COMSOL Multiphysics simulations. The flower-like morphology provides a larger surface area and abundant active sites, resulting in superior sensing performance compared to pristine ZnO nps. The performance parameters of the developed sensor include a sensitivity of 11.37/ppm, a limit of detection of 0.85 ppm, and response and recovery times of 14 s and 60 s, respectively, compared to pristine ZnO nps. Additionally, the sensor exhibits good selectivity for acetone over different interfering VOC species.

However, the poor fast-charging and limited stable-cycling properties of starbon limits the broad applications of lithium-ion batteries (LIBs) in practical scenarios. Herein, a boron-tailored approach was proposed to promote Li-ion migration and retard capacity decay of starbon anode. A boron solid-solution phase such as BC2O was formed in the starbon framework by a simple pentaborate starch hydrothermal reaction and annealing process, and then boron quantum dots (BQDs) were confined within conductive boron-doped starbon. The electron-deficient BQDs endow the boronated starbon framework with superior electrochemical performance, vastly enabling the electrochemical activity of boron as well as providing more active sites for ion insertion and extraction, thus increasing capacity and improving ion charge/diffusion and transfer. As an anode material for LIBs, BQDs/Starbon anode exhibits a high discharge capacity of 928 mAh g-1 at 0.05 A g-1, and the reversible specific capacity remains at 238 mAh g-1 at 2 A g-1 after 1000 cycles, demonstrating excellent long-term cycling stability. After cycling at a high current density of 10 A g-1 to recover to the initial 0.5 A g-1, the electrode was still able to maintain a high capacity of 318 mAh g-1.

However, the construction of ordered mesoporous CeO2 architectures through sustainable synthesis routes remains highly challenging. Metal-organic frameworks (MOFs) are promising sacrificial templates for the synthesis of oxides. Herein, we report a surfactant-regulated, alkali-metal-assisted aqueous strategy to construct ordered mesoporous CeO2 via UiO-66(Ce) templating. Pluronic was employed as a soft template, while inorganic bases (LiOH, NaOH, and KOH) were used to promote H2BDC deprotonation in water. The Li+, Na+, and K+ cations are believed to influence the self-assembly of UiO-66(Ce) framework (CeULi, CeUNa, and CeUK, respectively), leading to differences in the properties of the resulting particles. CeO2 derived from CeULi at low temperature, denoted as cCeULi, exhibited outstanding acetone conversion, reaching 90% at 207 °C. This is due to its mesoporous structure, the presence of Ce3+defects, and surface oxygen mobility. The cCeULi catalyst performed well over 10 cycles, averaging 87.9% efficiency over 25 h at 200 mg catalyst, 100 cc/min flow rate, and 600 ppm acetone. Also, cCeULi proved highly resistant to water vapor (5-10 vol%). In-situ DRIFTS analysis indicates that the acetone oxidation on cCeULi follows a Mars-van Krevelen mechanism involving lattice oxygen. Overall, the combination of morphological structure and surface chemical properties plays a key role in catalytic activity.

On the cathode side, the cathode electrolyte interface (CEI) layer is enriched with electron-deficient Lewis acidic B₂O₃, which chemisorbs soluble sodium polysulfides via BS and OS bonds. Simultaneously, this interphase forms a physical barrier due to its high mechanical strength and favorable structural properties, and the two effects work synergistically to suppress the shuttle effect. On the anode side, the inner solid electrolyte interface (SEI) layer that rich in boron-containing inorganic components can effectively inhibits sodium dendrite nucleation. Benefiting from the synergistic regulation of the boron-containing interphase, the TMBX-modified electrolyte endows Na-S cells with excellent performance.
