Herein, three CuO/SiO₂ catalysts were designed and prepared by regulating the introduction of copper species to achieve the selective oxidation of tertiary C-H of isobutane (i-C₄H₁₀) to tert-butanol (TBA). Under the condition of 130 °C and 1.5 h, CuO/SiO₂-DP catalyst could achieve 92.7 % O₂ conversion and 85.1 % TBA selectivity, and the cycle stability could be maintained. The improvement of catalytic performance could be attributed to the efficient utilization of Cu atoms, which was related to the regulating the formation of copper phyllosilicate and the full utilization of Si-OH on the surface of SiO₂ during the catalyst synthesis process. Copper phyllosilicate formed a rich Si-O-Cu unit, enhanced the metal oxide-support interaction, inhibited the growth of copper species, improved the anchoring and dispersion of CuO, and ultimately improved the accessibility of substrate molecules on active CuO (111). In addition, the adsorption configuration of i-C₄H₁₀ and O₂ on CuO (111) was determined by in-situ FT-IR and DFT, and the existence form of O₂ after charge transfer was discussed.

Therefore, due to the highest accumulation rate and recalcitrancy, their precise quantification makes significant concern about their toxicological effects on both humans and organisms. The objective of the study is that using hydrogen carrier gas instead of helium in gas chromatography with triple quadrupole (GC-MS/MS) systems could contribute to improvements on the analysis of dl-PCBs and PCDD/Fs in environmental matrices. The study evaluates the performance of the analysis time under the desired chromatographic resolution criteria for PCDD/Fs analysis, monitoring the plausible mass spectrum/fragmentation ratio changes, and finally the quantification limits of the targeted most toxic persistent organic compound congeners. The main advantage of using H₂ carrier gas is that the analysis time was drastically reduced (∼2.5 times) along with improved resolution due to an increase in peak widths in ∼0.6-0.7 factor. This study emphasized that the resolution was remarkably affected by the hexa congeners of PCDD/Fs; nearly baseline separation was observed. However, the sensitivity was slightly reduced (∼6-7 fold), which affected the calibration starting concentrations (0.8-3.2 pg/μl). The acquired mass spectra indicated that the lower fragment enhancement was noticeable, particularly on higher chlorinated ones (hexa, hepta, and octa congeners). The calculated ortho-effect values (1-58) in this study are consistent with the previous results in the literature (1-66 and 1-83) and supports the conclusion about the observations of lower fragment enhancement. Despite non-detection of hydrogenation, there is a significant difference in the quant/qual ion ratios in the studied compounds between helium and hydrogen carrier gas. The finalized methodology was examined, and the performance of the hydroinert® ion source was assessed over a three-month analysis period with a real sample analysis (RSD ≤17.8 %).

Herein, we have developed specific probes to detect denatured collagen (d-Col) and collagen I (Col I), utilizing peptide probes with sequences (GOP)₁₀ and HVWMQAP, targeting at d-Col and Col I, respectively. These peptides were conjugated with 1,10-phenanthroline-5-carboxylic Acid (Phen), forming Phen-Ahx-(GOP)₁₀ and Phen-Ahx-HVWMQAP. Phen acts as both an antenna sensitizer and a chelator, coordinating with Terbium (III) and Europium (III) ions via its nitrogen atom, facilitating fluorescent emission in green and red, respectively. The investigation demonstrated that Tb³⁺ interacts with three (GOP)₁₀ peptide units through Phen, while Eu³⁺ connects with four units of Ahx-HVWMQAP peptides. Additionally, it is important to note that the structure of the peptides remains unchanged after chelating with the lanthanide ions, maintaining their integrity throughout the process. These probes have effectively demonstrated their ability to bind to specific collagen types with selectivity, enabling accurate identification of their presence. The excellent binding of these probes is due to the branched structure of the formed lanthanide-peptide complexes. A dose-dependent linear association was observed in the binding of Eu-[Phen-Ahx-HVWMQAP]₄ to Col I, with concentration levels ranging from 0.5 to 100 μM and a minimal detectable concentration of 0.113 μM.
