Sustainable production of bio-propionic acid: Facet-mediated C-O bond cleavage of Fe3O4 nano-crystallites

Nanostructured nickel–cobalt alloy/rGO-SWCNT thin film as an efficient electrocatalyst for hydrogen evolution reactions

“…Long-term durability is an important factor for any electrocatalyst. 36,37,54–56 Here, the time-dependent chronopotentiometric tests at a constant applied current density of 10 mA cm −2 and 100 mA cm −2 for CoNi21 were performed respectively, and the results are shown in Fig. 7a.…”

Development of a payload for monitoring biological samples in microgravity and hypergravity conditions

“…These encompassed the parameterization of microcontroller variables, the configuration of camera optical sensors, and the assurance of the container's compatibility with standard power supply inputs, facilitating seamless integration into a payload or launch vehicle. Moreover, it was imperative for the container to securely house both organic and inorganic materials, ensuring their stability and inertness during image capture processes [13], [14]. To meet these stringent criteria, careful consideration was given to the selection of materials, which included: -ESP32-CAM: this module, based on the ESP32 microcontroller, was chosen for its 32-bit architecture, Wi-Fi and Bluetooth connectivity, and integrated camera capabilities that could allow the samples monitoring at low cost [15].…”

Highly efficient production of 2,3-pentanedione from condensation of bio-derived lactic acid over polymorphic ZrO2

“…7 Overall, bio-derived lactic acid (LA) is particularly appealing due to its simple synthesis via biomass fermentation, as well as the expected increased availability and lower cost. 10,11 Several studies have been conducted to convert LA to chemicals such as acrylic acid, pyruvic acid, 12,13 propionic acid, 14 acetaldehyde, poly(lactic acid), and 2,3-pentanedione. 15 However, the raw lactic acid must be further purified to technical or analytical grade before being used in this described process.…”
