“…The majority of results reported by the literature shows the linear dependence between pores width and anodization voltage in the formation of self-assembled porous alumina (1). Considering the structures obtained by oxalic and phosphoric acid solutions, it was obtained a linear relation given by…”

The aim of the present work was to contribute to the nanostructured selfassembled systems fabrication to photonic and optoelectronic applications. Self-assembled porous alumina structures were obtained. These structures were fabricated by electrochemical technique (anodization of aluminum substrates). The effects of acid type and anodizing voltage on the formation of porous alumina film were analyzed. It was discussed the possible mechanism of self-assembled pores formation.

“…As a consequence, an oxide cell of a more regular (ideal) structure is formed. 1,8,9 Increasing the electrolyte temperature would also have a considerable effect on the porosity of the oxide coating. [1][2][3][4] The porosity of the obtained oxide layers is of major importance to their utilisation for a sliding interaction with plastic materials.…”

“…Controlling anodising parameters allows, within some limits, programming the selected functional properties of future upper layers. [3][4][5][6][7][8][9][10][11][12] The above-mentioned method consists of oxidising aluminium and its alloys in three-component electrolytes. Dicarboxylic acid is added to the mixture of sulphuric and oxalic acids.…”

The paper presents a new method of obtaining aluminium-oxide-based, duplex-type layers. In the first stage, the base layer is produced via the hard anodising of aluminium alloys in order to obtain the optimal structural and morphological properties. Following anodising, the samples with an Al2O3 layer are rinsed in distilled water in order to remove the electrolyte. Graphite was introduced into the structure of aluminium oxide during a thermal treatment in a solid medium consisting of graphite dust. Afterwards, the properties of the obtained layers were determined using a scanning electron microscope, a transmission electron microscope and an atomic force microscope (AFM), as well as X-ray diffraction. The structure of the duplex-type layers contains carbon and other precipitates, which are typical for an alloy with additions of Fe, Mn, Cr and other elements. Carbon precipitates have a relatively weak connection with the matrix, as an envelope with numerous discontinuities forms around each carbon precipitate. Carbon precipitates are considerably larger than alloy precipitates, have micrometre dimensions, occur in groups and are composed of small grouped nanometric particles that form larger agglomerates. This means that there are nanometric particles inside the micrometric ones. Keywords: aluminium alloys, nano-layers, SEM, AFM, EDŜ lanek predstavlja novo metodo za izdelavo dupleksne plasti aluminijevega oksida. V prvi stopnji se izdela osnovna plast s trdim anodiziranjem aluminijevih zlitin, da se dobi optimalno strukturo in morfolo{ke lastnosti. Po anodizaciji so vzorci z Al2O3 plastjo potopljeni v destilirano vodo, da se izpere elektrolit. V strukturo aluminijevega oksida se uvede grafit med toplotno obdelavo v trdem mediju, ki je vseboval grafitni prah. Potem so bile dolo~ene lastnosti dobljenih plasti, s pomo~jo vrsti~nega elektronskega mikroskopa, presevnega mikroskopa in mikroskopa na atomsko silo (AFM), kot tudi z rentgensko difrakcijo. Struktura dupleksnih plasti je vsebovala izlo~ke ogljika in druge izlo~ke, ki so zna~ilni za zlitine, z dodatkom Fe, Mn, Cr in drugih elementov. Izlo~ki ogljika imajo relativno {ibko povezavo z osnovo, saj nastaja okrog vsakega izlo~ka ogljika ovojnica s {tevilnimi diskontinuitetami. Izlo~ki ogljika so mnogo ve~ji kot izlo~ki zlitin, imajo mikrometrske dimenzije, se pojavljajo v skupinah in so sestavljeni iz malih gru~nanometri~nih delcev, ki tvorijo ve~je skupke. To pomeni, da so znotraj mikrometrskih delcev prisotni nanometrski delci.

“…In recent years these films, so-called alumina, due to their honeycomb high-ordered and well-predetermined structure, showing tube shaped pore array with a center-to-center spacing from few tents to about 550 nm [1,2] and the pore diameter from about 10 to 250 nm [3], are widely used as a host material for fabrication nanostructured arrays of metals, [4][5][6] semiconductors, [7][8][9] conducting polymers, [10] and carbon tubes [11,12]. Notably, that high-ordered alumina matrices filled with nanowires or nanotubes of desired material are promising candidates for catalyst, [13] functional electrodes, [14] future sensors, [15,16] magnetic, [17] and optoelectronic [18,19] devices. Furthermore, high-ordered alumina membranes recently have been used for detection DNA sequences at the nmol cm -2 level, [20] preparation of new biochemical reactor systems, [21] and the synthesis of nano-black lipid membranes [22].…”

Simple nanoporous alumina matrix modification procedure, in which the electrically highly insulating alumina barrier layer at the bottom of the pores is replaced with the conductive layer of the gold beds, was described. This modification makes possible the direct electron exchange between the underlying aluminum support and the redox species encapsulated in the alumina pores, thus, providing the generic platform for the nanoporous alumina sensors (biosensors) with the direct amperometric signal readout fabrication.
