Low-temperature Fischer–Tropsch (LTFT) synthesis converts syngas to diesel/wax at 200–250 °C. The LTFT reaction has recently received renewed interest, as it can be used for converting from renewable sources (biomass and waste) high-value fuels chemicals. Conventional reactors, such fixed-bed slurry are not entirely suitable bio-syngas conversion due their smaller scale compared fossil fuel-based processes. This review explores advancements in intensifying reactors conversion, enabling...
Lead-free piezoceramics based on the (Ba, Ca)(Zr, Ti)O3 (BCZT) system exhibit excellent electromechanical properties for low-temperature actuation applications, but suffer from relatively high processing temperatures. Here we demonstrate an approach reduction of sintering temperature and simultaneous increase strain response by aliovalent doping with Ce. The samples were prepared solid state synthesis their crystallographic structure, dielectric, ferroelectric, investigated. highest d*33...
Dual-fluorescence carbon dots have great potential as nanosensors in life and materials sciences. Such can be obtained via a solvothermal synthesis route with glutathione formamide. In this work, we show that the dual-fluorescence emission of products does not originate from single dot emitter, but rather mixture physically separate compounds. We characterized UV-vis, Raman, infrared, fluorescence spectroscopy, identified blue-emissive red-emissive porphyrin. demonstrate an easy way to two...
Abstract Although biomass‐based alternatives for the manufacturing of bioplastic films are an important aspect a more sustainable future, their physicochemical properties need to be able compete with existing market establish them as viable alternative. One factor that is often neglected long‐term stability renewables‐based functional materials, they should neither degrade after day or week, nor last forever. material showing high potential in this regard, also due its intrinsic...
Abstract Europium‐doped yttrium oxide nanoparticles (Y 2 O 3 :Eu NPs) modified by captopril were prepared in aqueous solution. In this study, we report the effect of pyridoxine hydrochloride on photoluminescence intensity Y NPs pH 7.2 buffer By increasing concentration, luminescence is quenched. The results show that method demonstrates high sensitivity for determination. A linear relationship observed between 0.0 and 62.0 μM with a correlation coefficient 0.995 detection limit 0.023 μM....

Conventional fixed-bed reactors with conductive internals have shown excellent heat management in the Fischer–Tropsch synthesis, enabling much higher liquid productivity by avoiding thermal runaway.
To study the relation between conductance, photoluminescence bands and structure of indium tin oxide (ITO), nano- microparticles ITO were synthesised using various methods, including hydrothermal, oxalate precursor decomposition Pechini type sol–gel combustion methods. The resultant powders analysed by X-ray diffraction (XRD), resistance measurement, (PL) spectroscopy scanning electron microscopy techniques. crystallographic microstructural parameters samples refined from XRD patterns...
