Growth and electrochemical stability of a layer-by-layer thin film containing tetrasulfonated Fe phthalocyanine
(Elsevier Science SA, 2020-11)
Devices based on the functionalization of surfaces with iron phthalocyanine could have potential applications in sensors as well as in clean energy generation. In this work we studied the growth and electrochemical stability ...
Controlled fabrication of gold nanoparticles biomediated by glucose oxidase immobilized on chitosan layer-by-layer films
(Elsevier B.V., 2009-06-01)
The control of size and shape of metallic nanoparticles is a fundamental goal in nanochemistry, and crucial for applications exploiting nanoscale properties of materials. We present here an approach to the synthesis of ...
Exploring lectin-like activity of the S-layer protein of Lactobacillus acidophilus ATCC 4356
(Springer, 2019-06)
The surface layer (S-layer) protein of Lactobacillus acidophilus is a crystalline array of self-assembling, proteinaceous subunits non-covalently bound to the outmost bacterial cell wall envelope and is involved in the ...
Comparison of F1 layer critical frequency between recent two solar minimums
(American Geophysical Union, 2016-09-06)
This study compares the F1 layer critical frequencies (foF1) between the 22/23 and 23/24 solar minimums to investigate the effects of extremely low solar activities on F1 layer. The foF1 data of 1996 and 2008 at various ...
Photocatalytic thin films containing TiO 2:N nanopowders obtained by the layer-by-layer self-assembling method
(2012)
In this work, TiO 2-N powders were synthesized by high-energy ball milling, using commercial titanium dioxide (TiO 2) in the anatase phase and urea to introduce nitrogen into TiO 2 in order to enhance their photocatalytic ...
Renewable nanocomposite layer-by-layer assembled catalytic interfaces for biosensing applications
(2010)
A novel, easily renewable nanocomposite interface based on layer-by-layer (LbL) assembled cationic/anionic layers of carbon nanotubes customized with biopolymers is reported. A simple approach is proposed to fabricate a ...
Effect of different parameters on the hydrolytic activity of cross-linked enzyme aggregates (CLEAs) of lipase from Thermomyces lanuginosa
(Elsevier, 2013-03)
Cross-linked enzyme aggregates (CLEAs) of lipase from Thermomyces lanuginosa (TLL) were synthesized using (NH4)2SO4 as precipitant and glutaraldehyde as cross-linking agent. CLEAs were assayed for their hydrolytic activity ...
Simulation study of the influence of the ionospheric layer height in the thin layer ionospheric model
(Springer, 2011-04)
This work aims to contribute to the understanding of the influence of the ionospheric layer height (ILH) on the thin layer ionospheric model (TLIM) used to retrieve ionospheric information from the GNSS observations. ...
Flavin adenine dinucleotide functionalized gold nanoparticles for the electrochemical detection of dopamine
(2022-11-01)
Dopamine (DA) is a neurotransmitter with multiple functions in the central nervous system, and whether found in low levels, activation of biological defense system and physiological activity is influenced. DA at abnormal ...
Modificação da interface de compósitos de polipropileno com fibras de vidro pela técnica Layer-by-Layer
(Universidade Federal de Minas GeraisUFMG, 2016-03-29)
The properties of glass fiber-reinforced polymer composites are closely related to the performance of the interface between fibers and polymer matrices. Many interfacial treatments have been developed and used to improve ...
