α-Amylase Aspergillus oryzae Immobilized on Modified Expanded Perlite
(De Gruyter, 2014-10)
The α-amylase from Aspergillus oryzae was immobilized covalently onto expanded perlite (EP) and modified EP by treatment with TiO2 (EP-TiO2), dye HE3B (EP-HE3B) polyethylene terephthalate (PET)-hydrazide (EP-PET) and ...
Synthesis and functionalization of magnetite nanoparticles with different amino-functional alkoxysilanes
(Elsevier B.V., 2012-02-01)
Superparamagnetic iron oxide (SPIO) nanoparticles show great promise for many biotechnological applications. This paper addresses the synthesis and characterization of SPIO nanoparticles grafted with three different ...
Preparation and photoluminescence properties of functionalized silica materials incorporating europium complexes
(ELSEVIER SCIENCE BV, 2011)
In the present work, the surface of the Eu-BTC = [Eu(EMA)(H(2)O)(2)], [Eu(TLA)(H(2)O)(4)] and [Eu(TMA)(H(2)O)(6)] complexes (EMA = 1,2,3-benzenetricarboxylate, TLA = 1,2,4-benzenetricarboxylate and TMA = 1,3,5-benzenetri ...
Preparation and Characterization of Silanes Films to Protect Electrogalvanized Steel
(Springer, 2018-03)
Silanes are an interesting alternative to chromate-based surface treatments for temporary protection of electrogalvanized steel. In this work, the protective behavior of 3-mercaptopropyltrimethoxysilane (MTMO), ...

Luminescent hybrid materials based on covalent attachment of Eu(III)-tris(bipyridinedicarboxylate) in the mesoporous silica host MCM-41
(Royal Society of Chemistry - RSCCambrige, 2014-06)
A luminescent inorganic-organic hybrid material was synthesized by covalent immobilization of a europium bipyridine carboxylate complex on the inner pore walls of the mesoporous silica host MCM-41 using the grafting method. ...
Silsesquioxanes functionalized with one or two side-chain amino groups as coinitiators of camphorquinone in photoinitiated polymerization of methacrylate monomers
