“…HPLC makes use of high-pressure pumps that speed the movement of analytes down the column [14]. HPLC technology needs a sophisticated coordination of electronic and optical devices with silica bead-based column system combined with novel surface chemistry and high purity reagents [21][22][23][24].…”

Nonsteroidal anti-inflammatory drugs (NSAIDs), which block the activity of cyclooxygenase (COX) isoenzymes and inhibit the synthesis of prostaglandin, have been used for pain relief. For the enhancement of the potency or the decrease of sideeffects, NSAIDs are normally prescribed as a mixture with other chemical components including caffeine and proton pump inhibitor. Here, we developed a method to separate a mixture of three NSAIDs, such as aspirin, paracetamol, and naproxen, using reverse-phase high-performance liquid chromatography (RP-HPLC). An isocratic mobile phase consisting of acidic water and acetonitrile was selected to run at a low flow rate, such as 0.8 mL/min. The mixture of three NSAIDs was injected at a low volume into a C18 column having 150 mm in length and characterized using a UV detector at 230 nm. We identified three peaks in the chromatogram indicating three compounds. The elution time of the peaks was less than 10 min. The method proposed here can be used for identification of the combination of NSAIDs.

“…[ 1–9 ] However, the degradation of particles at high operating temperatures is unavoidable, and such low thermal resistance limits their application. [ 10–13 ] Numerous studies in various areas have been conducted in an effort to hinder such phenomena by introducing a protective layer, such as a core–shell layer, [ 14–16 ] an overcoating, [ 17,18 ] and others. [ 19,20 ] Recently, the “ex‐solution” approach, a particle synthesis method that relies on a surface phase transition of the support material, was introduced.…”

The combination of supported metal nanoparticles and functional host oxides catalyze many major industrial reactions. However, uniform dispersion and ideal chemical configuration of such nanoparticles, which determines the catalytic activity, are often difficult to achieve. In this study, a unique combination is proposed of heterogeneous doping and ex-solution for the fabrication of Pt-Ni alloy nanoparticles on CeO 2 . By manipulating the reducing conditions, both the particle size and composition are precisely controlled, thereby achieving a highly dispersed and stable alloy nanocatalyst. The unique behavior of controlled alloy composition is elucidated through classical diffusion and precipitation kinetics with elemental analysis of the grain boundaries. Finally, Pt-Ni alloy nanocatalysts are successfully tuned showcasing a breakthrough performance compared to single element catalyst in reverse water gas shift reaction with superior stability and reproducibility.
