Talvez deva tentar algumas variações de ortografia:
functionalized cotton » functionalized carbon (Expandir a busca), functionalized chitosan (Expandir a busca), functionalized cathode (Expandir a busca)
of functionalized » of functionality (Expandir a busca), of functional (Expandir a busca)
python program » action program (Expandir a busca)
cotton python » cotton cotton (Expandir a busca), piton python (Expandir a busca), python python (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python code python program ) OR ( of functionalized cotton python programming ))~.
