In the presented work, advanced methods of analysis and visualization were used to compile trends and patterns in the scientific literature. The most relevant information for the stability of biosensors was selected on the basis of clusters constructed on the basis of keywords. The most significant publications in the clusters appearing over time were analyzed. The most explosive publications were identified, i.e., those that have had the greatest impact on science in the area of the subject under study. The scientific trend in the development of biosensor stability was determined on the basis of the most frequently cited words in recent publications. A map of cooperation and networking between countries in the field of interest of the above topic was presented. Leaders were identified by country of origin.Systematic Review Registration:https://ubb.edu.pl.

“…To confirm the fact of the formation of a water‐insoluble polyprenol‐based monolayer at the phase interface, we studied the dependence of the surface pressure in the monolayer on the area per one polyprenol molecule on the surface 29 . This method allows the determination of the phase state of a surfactant monolayer at the interface.…”

Rationale The polyprenols are involved in some essential biosynthetic pathways and serve as ubiquitous components of cellular membranes, so their fingerprinting in natural samples is of great interest. Previous studies indicate that due to the high hydrophobicity of polyprenols their direct analysis by mass spectrometry with soft ionization techniques may be difficult and require preliminary off‐line derivatization. Hence, a method for rapid and sensitive screening of polyprenols is required. Methods A combination of thin‐film chemical deposition and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) was used for analysis of the polyprenol profile of Abies sibirica L. extract. Polyprenol‐based monolayers were formed at the interphase of aqueous barium acetate solution, supplemented with 2,5‐dihydroxybenzoic acid, and an n‐hexane solution of polyprenols directly on a MALDI target plate. Results Peaks corresponding to [M − H + Ba]+ ions were observed in the MALDI‐TOF mass spectra of polyprenols. A total of nine polyprenol homologues were identified with a polyprenol of 16 isoprene units dominating. The limit of detection was established at the level of 6 pg. Possible mechanisms of formation of [M − H + Ba]+ ions of polyprenols were discussed. Conclusions The proposed approach can be suitable for high‐throughput screening of polyprenols in biological samples of different origin due to easy sample preparation and high sensitivity.

“…Its crystallinity diminished tremendously, because of the interaction between the Si–O and Ni, Co, and Mo at 2θ = 7.8°, 12.6°, 24.4°, 27.6°, and 53°. The peaks at these angles could be ascribed to oxides of molybdenum in the following crystallographic directions, namely, MoO 3 [100], MoO 3 [001], MoO 3 [100], MoO 3 [021], and MoO 2 [311], respectively. − Further interaction from oxides of cobalt (Co x O y ) found at 16.6°, 21.9°, and 41.9° decreased the crystallinity of the zeolite . Lastly, oxides of nickel (Ni 2 O 3 [002], NiO [222], NiO [111]) at 30.4°, 34.7°, and 44.5°, respectively, contributed to the lowering of crystallinity of the zeolite. ,, …”

Process optimization and reaction kinetics of catalytic transfer hydrogenation (CTH) of waste cooking oil (WCO) into jet fuels using zeolite-supported Ni−Co−Mo oxides catalyst in a packed-bed reactor were studied. Experiments were conducted at three different temperatures (360, 390, and 420 °C) to determine the rate constants, the order of reaction, and the activation energy. The kinetics study showed a first-order reaction with the activation energy estimated to be 84 ± 18.7 kJ/mol WCO with 95% confidence. Design of experiment (DOE) was employed to estimate the optimum reaction parameters using the polynomial model (383.7 °C; 14.8 bar; WCO-to-2-propanol ratio = 1.57 mL/ mL; weight hourly space velocity (WHSV) = 6.7 h −1 ). Validation of the model at the optimum operating conditions generated 80% yield of liquid products with 77% alkanes, 3.8% alkenes, and 12.3% aromatics composition, and 6.7% gases, and 100% conversion of WCO. The catalyst was prepared via the wet impregnation method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer−Emmett−Teller (BET) adsorption and desorption, scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and thermogravimetric analysis (TGA). Characterization of the catalyst revealed a cubic structure, which was maintained after one cycle of CTH reaction. Present in both the fresh and the used catalysts were Na 2 O, K 2 O, MgO, Al 2 O 3 , SiO 2 , CaO, FeO, Fe 2 O 3 , which highlight the composition of zeolite. The active sites were dominated by Co 3+ , Ni 2+ , and Mo 6+ that were respectively present in the form of Co 2 O 3 , NiO, and MoO 3 .
