Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Nanoporous membranes based on metal oxides are widely used for the formation of nanostructured materials, since it is possible to create materials with predetermined structural properties. In this research work, the structural features of nanoporous membranes based on titanium and aluminum oxides, which are combined by the production process, but differ in the growth of pores and their structure. Membranes based on metal oxides were synthesized at a voltage of U=80-140V, at room temperature T=17°C, in an acidic environment. The structural features of the synthesized membranes were studied using Quanta 200i 3D scanning electron microscopy (FEI). It was found that titanium dioxide films have a narrow pore distribution, the sizes of which are in the range of 40-115 nm. Structural differences between titanium oxide and aluminum oxide nanomembranes make it possible to be widely used in the field of nanotechnology and materials science.
