When a Red–NIR-Emissive Cs2[Mo6Br14] Interacts with an Active Diureasil–PEO Matrix: Design of Tunable and White-Light-Emitting Hybrid Material
(2019-12-02)
Hybrid materials that combine diureasil matrices and octahedral molybdenum clusters have been synthesized to design lead-, cadmium- and rare-earth-free emitters for lighting or optoelectronic applications. This association ...
Chitosan/(ureasil-PEO hybrid) blend for drug delivery
(Springer, 2014-11-01)
The effect of chitosan addition on the structure and drug release properties of ureasil-polyethylene oxide (U-PEO) hybrid materials was examined. The hybrids and the blends were prepared by the sol-gel route and their ...
Assessment of biocompatibility of ureasil-polyether hybrid membranes for future use in implantodontology
(2016-09-01)
The biocompatibility of ureasil-polyether hybrid materials has been tested for future application as membrane barrier. The authors evaluated ureasil-polyether hybrids membranes with different swollen behaviors: more swellable ...
Antibacterial biocomposite materials based on essential oils embedded in sol–gel hybrid silica matrices
(2016-09)
For the design of antibacterial materials comprising hybrid silica-containing plant oils capable of performing a controlled release of essential oil components, tests of lemongrass, citronella, basil, rosemary, eucalyptus, ...

A simple geometrical path towards hybrid orbitals
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-11-01)
It is shown that the standard sp(n) hybrid orbitals are orthogonal orbitals that minimize the total quadratic spread. This is done in a concise way that may improve the understanding of hybrid orbitals. The fact that ...
Synthesis of polymeric organic-inorganic hybrid materials. Partially deacetylated chitin-silica hybrid
(Wiley-VCH Verlag, 1997)
This work reports the synthesis of a novel polymeric organic-inorganic hybrid. The inorganic component is a silica network obtained by controlled hydrolysis of tetraethyl orthosilicate via sol-gel process and the organic ...
Electrical percolation during gelation of lithium doped siloxane-poly(oxyethylene) hybrids
(Springer, 2004-10-01)
Gelation mechanisms of lithium-doped Siloxane-Poly(oxyethylene) (PEO) hybrids containing polymer of two different molecular weight (500 and 1900 g/mol) were investigated through the evolution of the electrical properties ...
Synthesis, characterization and electrochemical behavior of the vanadium pentoxide/cetyl pyridinium chloride hybrid material
(SPRINGER, 2010)
In situ and ex situ studies concerning the new hybrid material vanadium pentoxide xerogel in the presence of the cationic surfactant cetyl pyridinium chloride (V(2)O(5)/CPC) are presented. The in situ characterization ...
Ureasil-polyether hybrid film-forming materials
(2013-01-01)
The objectives of this work were to study the suitability and highlight the advantages of the use of cross-linked ureasil-polyether hybrid matrices as film-forming systems. The results revealed that ureasil-polyethers are ...
