This work reports a novel approach for growing layered double hydroxide (LDH) films on any plasma electrolytic oxidation (PEO) coated AA2024 independently of the nature PEO coating. The specific coating chosen to carry out this is considered be not suitable direct LDH growth because phase composition and morphological features. In paper, we describe new methodology that consists covering with thin layer aluminum oxide based xerogel as source aluminate ions subsequent in-situ growth. X-ray...
To prevent possible spread of nosocomial infections – HAI (Healthcare Acquired Infections) in healthcare facilities, Antibacterial textiles are developed. This carried out study has been conducted to assess the feasibility method obtaining antibacterial coatings on textile materials. Specifically, sol-gel for synthesis titanium dioxide nanoparticles combination with zinc oxide from titanyl sulphate and nitrate hexahydrate investigated. During nanoparticles, coated material showed stable...
Alumina aerogels are obtained by supercritical drying (SCD) in four solvents of different chemical natures. The phase transformations, the morphological changes, and thermal stability during heat treatment range 20–1200 °C investigated. as-prepared samples SCD MeOH identified as crystalline aluminum hydroxide methoxide, those i-PrOH consist alumina with small size crystallite grains. In contrast to alcohol-dried samples, initial ether-dried amorphous (as determined X-ray diffraction)....
Abstract Here we report on the thermal properties of Mg−Ni‐phyllosilicate nanoscrolls as a promising precursor for production Ni/silicate composite catalysts. Spontaneous scrolling phyllosilicate layer originating from size difference between metal‐oxygen and silica sheets provides high surface area catalyst. Metal nanoparticles can be obtained directly matrix by H 2 reduction. The structure passed through number transformations including partial dehydroxylation with formation sepiolite‐like...
Abstract A first composite material containing uniformly dispersed disaggregated detonation nanocrystalline diamonds (DNDs) in SiO 2 aerogel matrix was prepared. The synthetic protocol included hydrolysis of tetramethyl orthosilicate (Si(OMe) 4 , TMOS) by hydrosol surface carboxylated DNDs with a typical size 4–5 nm DMSO serving as cosolvent and stabilizer DND single crystals. Composite samples silica concentration 1.0, 0.1 0.01 % w/w were prepared at ambient temperature. HRTEM data revealed...
The study is devoted to the development of an artificial material based on ultrahigh-molecular weight polyethylene (UHMWPE) with a porous or cellular 3D structure as matrix – framework for growing cell cultures. such provides support neuronal culture under conditions that mimick those exist in living body. Typically, vitro studies are conducted 2D format, which limits intercellular interactions, morphology, differentiation, survival, signaling responses, gene expression and proliferation...
Cell culturing methods in its classical 2D approach have limitations associated with altered cell morphology, gene expression patterns, migration, cycle and proliferation. Moreover, high throughput drug screening is mainly performed on cultures which are physiologically far from proper functions resulting inadequate hit-compounds subsequently fail. A shift to 3D protocols could solve issues biochemistry signaling would lead a recapitulation of physiological conditions test systems. Here, we...
Abstract The evolution of the electrical charge injected into Ni-doped phyllosilicate nanoscrolls composites deposited on a conductive substrate was studied by Kelvin probe force microscopy. were synthesized hydrothermal method and then annealed in H 2 /Ar flow at 400-900°C order to reduce Ni up metal. A typical agglomerate 3 Si O 5 (OH) 4 accumulated one nanoscroll followed subsequent partial destruction agglomerate. For MgSi nanoscrolls, whole could be charged, retained for hours. shortest...
The aim of the study is to investigate influence solvents applied both in sol–gel process and for supercritical drying (SCD) on NiO aerogels’ properties. aerogels were synthesized using methanol 2-methoxy-ethanol (MeGl) as sol solvents. SCD was performed iso-propanol, tert-butyl-methyl ether fluids. obtained samples characterized low-temperature nitrogen adsorption, X-ray diffraction analysis, mass-spectra analysis STEM TEM methods. It found that specific surface area phase chemical...
