Abstract Carbon nanotubes (CNTs) prepared from ethylene decomposition over the Fe/Al 2 O 3 catalyst are studied in a packed bed (PB) reactor and nanoagglomerate fluidized (NABR), respectively. CNTs sampled at different reaction times characterized by TEM, Raman spectroscopy, particle size analysis. The bulk density agglomerate of increase significantly with time PB, while it remains stable level NABR. Also, good morphology, narrow diameter distribution, fewer lattice defects obtained an...
The objective of this study is to investigate the effect solidification microstructure CJ5L Recycled Stainless Steel in cast state on its thermoplasticity. Therefore, residual ferrite, structure, and high-temperature thermoplasticity both Non-Recycled steel ingots are examined. principal experimental techniques employed include SEM, OM, EPMA, EDS. It was observed that underwent a gradual transformation from dendritic structure with skeletal shape worm-like dendrite as thickness increased....
The investigation explores the relationship between deformation, recrystallization, and phase transformation of 460 MPa grade heavy ship steel plate under thermo mechanical control process. A coupled model integrating hyperbolic sine Arrhenius equation, Avrami time‐temperature‐transformation curve is developed to simulate 14‐pass rolling cooling Key findings reveal that recrystallization does not occur when reduction reaches 22% temperature drops below 1120 °C. This conclusion provides...
This study comprehensively employs data analysis, simulation, and characterization techniques to investigate the causes of surface spalling defects in low‐nickel austenitic stainless steel. The results indicate that there are components mold fluxes at defect location. Correlation calculations smelting process demonstrate a significant association between fluctuation cooling water temperature difference occurrence defects. is attributed reduced heat transfer caused by using with higher...
Enzymatic biofuel cells (EBFCs) are devices that use natural enzymes as catalysts to convert chemical energy from bio-sourced fuels into electrical energy. In this review, we summarize recent research progress and applications in the field of based on immobilized enzymes. Specifically, discuss how optimize improve electrochemical performance operational stability enzymatic through enzyme immobilization materials, methods, electron transfer improvement electrodes, cell construction methods....
Abstract A typical nanoscale fiber material, carbon nanotubes (CNTs), was fluidized in a 280 mm inner diameter (ID) nano‐agglomerate bed (NAFB). The solids distribution and gas mixing were measured by self‐developed conductance method the hydrogen tracer technique. Typical fluidization characteristics, such as high expansion ratio multi‐staged agglomerate structure, observed. Fluidization experiments over wide velocity range showed that CNT agglomerates have agglomerate‐bubbling‐fluidization...
The formation of rings composed uniformly sized triple-walled carbon nanotubes has been demonstrated and characterized by high resolution transmission electron microscopy. These are found in the products from acetylene decomposition on Fe∕MgO catalyst a fluidized bed. This finding expands libratory building blocks based demonstrates existence crystalline structures complex multiwalled nanotubes.
Few walled carbon nanotubes (FWCNTs) have been successfully synthesized using a nano-agglomerate fluidized-bed process. FWCNTs can be obtained by fluidization of Fe ( Co / Ni )/ Mo MgO catalysts at high temperature with methane cracking in reactor. The products were mainly 2 to 5 CNTs an outer diameter 1–7 nm purity, as revealed Raman spectrometry, SEM, and HRTEM analysis. Two keys crucial for this first key was get the small size activity catalyst particles which realized addition catalyst....
Image perturbation is a promising technique to assess radiomic feature repeatability, but whether it can achieve the same effect as test-retest imaging on model reliability unknown. This study aimed compare based repeatable features determined by two methods using four different classifiers. A 191-patient public breast cancer dataset with 71 scans was used pre-determined 117 training and 74 testing samples. We collected apparent diffusion coefficient images manual tumor segmentations for...
A prototype of an exercising bicycle with a key part concentric cylinders has been designed and characterized employing electrorheological (ER) fluids based on zeolite silicone oil. The radius width the have optimized so that there is minimum power consumption from high voltage source. performance experimentally determined. Experimental results show resistance increases significantly increase applied electric field <0.5 W. research shows advantages using ER in this kind apparatus.
