This work aims to develop a robust machine learning model for the prediction of relative viscosity nanoparticles (NPs) including Al2O3, TiO2, SiO2, CuO, SiC, and Ag based on most important input parameters affecting them covering size, concentration, thickness interfacial layer, intensive properties NPs. In order comprehensive artificial intelligence in this study, sixty-nine data samples were ...

Au/SiO2 SBA-15 materials were prepared using supercritical CO2 (scCO2) and by wet impregnation. First, SiO2 was functionalized with thiol groups at different grafting densities 3-(Mercaptopropyl)trimethoxysilane dissolved in scCO2. The support then impregnated HAuCl4·3H2O scCO2 modified EtOH. Wet impregnation of the supports ethanol also performed. Materials calcined 500 °C to remove organic ma...

To evaluate the effect of beverages (coffee, tea, Cola-Cola, and mineral water) on color stability resin-based composite (RBC) materials modified with different nanoparticles (NPs). The specimens (70/beverage) were fabricated from light-cured RBCs divided according to NPs into four groups: one control, unmodified (N0); three experimental—ZrO2 (Zr), TiO2 (Ti), SiO2 (Si) groups. Each experimental...

The development of flexible Li-ion batteries (LiBs) is important for applications in wearable devices, display systems, intelligent communication, and other electronics fields. Herein, we report a flexible, binder-free, [email protected]@carbon nanofiber ([email protected]2@CNF) anode fabricated by scalable electrospinning method novel “pre-oxidation–slicing–carbonization” process. Si nanoparti...

Propane dehydrogenation is an important industrial reaction to access propene, the world’s second most used polymer precursor. Catalysts for this transformation are required be long living at high temperature and robust toward harsh oxidative regeneration conditions. In work, combining surface organometallic chemistry thermolytic molecular precursor approach, we prepared well-defined silica-sup...

Grafting non-polar polymer chains on the surface of polar nanoparticles (e.g., silica) is an effective way to enhance particle/matrix interactions and thus promote their homogeneous dispersion within a matrix, which leads improved mechanical properties. Current grafting methods have not yet produced with well-defined polymers high density. Here, we employed anionic polymerization vacuum techniq...

The synthesis of clickable polysaccharides was achieved by using alkynylated 1,6-anhydro glucopyranose as a monomer and BF3·OEt2 as an effective catalyst. Subsequent click conjugation with polyethylene glycol (PEG) afforded PEG-grafted polysaccharides in nearly quantitative efficiency.

The lactone rings of ginkgolide A are converted into corresponding tetrahydrofuran moieties via DIBAL-H reduction followed by deoxygenation of the formed lactols with Et3SiH-BF3.Et2O to produce a series of lactone-free ginkgolides.

Polymers stabilize the nanoparticles onto which they wrap, avoiding coagulation and undesired phase separation processes. Wrapping gives rise to hybrid colloids, is useful in bio-intended applications. In non-covalent interaction modes, polymers physically adsorb nanoparticles’ surface, NPs, some of their portions protrude outside. Both non-interacting parts free are contact with solvent, and/o...

Coolant plays important characteristic in automobile industry to prevent failure and damage by balancing the temperature. Due this approach, coolants are being used as new thermal fluid study heat transfer coefficient performance. This consists of an experimental investigation internal convective 50:50 Water-Ethylene Glycol based Nano-fluid through a copper tube 18mm external diameter 16.5mm te...
