In this study, Functionalized chitosan with amine groups was synthesized and coated on the surface of carbon black. The hybrid amino functionalized chitosan-carbon support was employed as an efficient, environmentally friendly heterogeneous catalyst for the transesterification reaction of canola oil and methanol. It was observed that this hybrid was more active than parent polymer at the reaction...

Batch Adsorption of Acid Red 37 (AR37) and Basic Orange 2 (BO2) on amino ethyl-functionalized SBA-15 have been studied. SBA-15 was synthesized and functionalized according to the procedure in the literature. Amino ethyl-functionalized SBA-15 showed the BET surface area 520 m2/g and pore diameter 7.02 nm, based on adsorption-desorption of N2. SEM image shows lengthy fib...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

Single-walled carbon nanotubes (SWCNT) functionalized with amino groups were prepared via chemical modification of carboxyl groups introduced on the carbon nanotube surface. Two different approaches (amide and amine-moieties) were used to produce the amino-functionalized nanotubes. The aminotermination allows further chemistry of the functionalized SWCNTs and makes possible covalent bonding to ...

In this study, functionalization of PET fabrics with amino groups was achieved by aminolysis. Aminolysis routes were explored using different amine-based materials including ethylenediamine (EDA), triaminotriethylamine (TAEA) and (3-aminopropyl)trimethoxysilane (APTMS), (3-trimethoxy-silylpropyl)diethylentriamine (TRIAMO) in addition to amino-functionalized silica nanoparticles as amino-silane ...

Hydroxyapatite (HA) is a material of choice for bone grafts owing to its chemical and structural similarities to the mineral phase of hard tissues. The combination of osteogenic proteins with HA materials that carry and deliver the proteins to the bone-defective areas will accelerate bone regeneration. The study investigated the treatment of HA particles with different amino acids such as serin...

In the present study, amino-functionalized carbon quantum dots (N-CQDs) were prepared from sugarcane bagasse using a simple one-pot hydrothermal method. Both ethylenedinitrilotetraacetic (EDTA) & ethylenediamine (EDA) used as and amino sources, respectively. The emerging utilization of natural precursors is critically essential considering its low cost, eco-friendly, unexploited by-products...
