Dispersive liquid–liquid microextraction and Monte Carlo simulation of margin of safety for octocrylene, EHMC, 2ES, and homosalate in sunscreens
(John Wiley and Sons Ltd., 2023)
Dispersive liquid–liquid microextraction (DLLME) using a floating organic drop has been optimized and used for the sample preparation of four commonly used ultraviolet filter (UVF) substances in sunscreens. Plackett–Burman ...
Forced Periodic Operation of Methanol Synthesis in an Isothermal Gradientless Reactor
(John Wiley and Sons Inc, 2022)
Methanol synthesis from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts in an isothermal gradientless reactor is described. In a theoretical study, the potential of forced periodic operation (FPO) for improving ...
Activity Coefficients of the System {yNaCl + (1 – y)Na2HPO4}(aq) at T = 298.15 K Determined by Electromotive Force Measurements
(Pleiades Publishing, 2023)
The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq) were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength fraction was y = (0.3012; 0.4015; ...
Mechanistic insights into the simultaneous visible-light induced photodegradation of organic pollutants by g-C3N4/titanate heterojunction
(Springer Science and Business Media B.V., 2023)
The visible-light-active heterojunctions based on TiO2 were extensively investigated due to their wide range of energy and environment applications. In this study, g-C3N4/titanate heterojunction photocatalyst was successfully ...
Air Cooler for Crystal Growth in a Laboratory Tube Furnace
(Pleiades Publishing, 2022)
A new air cooler design (“specific two-level crystallization incubator”) with a specific arrangement of laboratory vessels by levels and double-branch air conductors at the ends and a series of movable cold thresholds ...
Novel chitosan and N-isopropylacrylamide-grafted-dextran-based microformulations as effective oral drug delivery system
(Springer Science and Business Media Deutschland GmbH, 2024)
Novel polymer network microformulations have been widely used for pharmaceutical applications. Especially challenging is to design and develop an ideal oral drug formulation due to many hostile factors in gastrointestinal ...
