Abstract Aluminum‐based composites reinforced with ceramics are intriguing subjects for both industry and research. Aluminum metal matrix (Al‐MMCs) constantly ready to create new, unique property combinations that appropriate high‐performance applications. This work involves using a modified stir casting technique (semi‐solid‐state route) prepare ZrO 2 /Al5052 composites. alloy (Al5052) is melted in an electric furnace then cooled slowly semi‐solid temperature. At this stage, pretreated...
Nd-doped CoFe2O4 spinel ferrites were synthesized via the sol-gel method, confirming a cubic structure. Increasing Nd concentration expanded lattice parameter (8.3900-8.4231 Å) and unit cell volume while reducing grain size. FT-IR analysis validated phase. doping enhanced dielectric constant by affecting space charge polarization hopping, with conductivity following Debye-type relaxation mechanism. Cole-Cole plots indicated boundary effects polaron hopping conduction. Magnetic properties...
The present study involves the synthesis of photocatalytic composite nanofibers (NFs) comprising ilmenite nickel titanite-supported carbon (NiTiO3/TiO2@CNFs) using an electrospinning process. NFs obtained were utilized in hydrogen (H2) production from photohydrolysis ammonia borane (AB). experimental findings show that with a loading 25 mg had good catalytic performance for H2 generation, producing stoichiometric 11 min 1 mmol AB under visible light at °C and 1000 rpm. increase catalyst load...
Abstract Refinery hydrogen network problem is highly nonlinear due to the equation that describes power of new compressor. Most previous attempts linearize this have been made by assuming constant suction and discharge pressure while taking inlet flow rate as a variable. Such assumption may not be practical in real condition because calculated requirement for compressor compatible with ratio selected This work proposed linearization method provides additional degree freedom allowing solver...
In this study, 2D Co-B nanosheet-decorated 1D TiO2 nanofibers (2D NS-decorated NFs) are synthesized via electrospinning and an in situ chemical reduction technique. The as-prepared catalyst showed excellent catalytic performance H2 generation from sodium borohydride (SBH). When compared to naked nanoparticles, the activity of NFs for hydrolysis SBH is significantly enhanced, as demonstrated by high hydrogen rate (HGR) 6020 mL min−1 g−1 at 25 °C. activation energy was measured be 30.87 kJ...
The paper presents a targeting method for process heat exchanger networks (HENs) design in the context of total sites. is based on simultaneous optimization framework HENs utility cost and systems operating cost. Instead standalone HEN capital-energy costs trade-off, utilizes trade-off between capital include steam non-steam within site. energy replaced by to avoid explicit calculations when design. This enables handling variability with loads minimum approach temperature, ΔT <sub...
