Abstract The structure transformation of a TiO2(110) surface was observed at atomic-scale resolution by scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED). Irregular corrugations on an argon-bombarded TiO2(110) surface crystallized to stacked (1 × 1) terraces by vacuum annealing at 600—800…
The influence of hydrostatic pressure on the electrical resistivity \ensuremath{\rho} and ferromagnetic transition temperature ${\mathit{T}}_{\mathit{c}}$ of ${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ca}}_{\mathit{x}}$${\mathrm{MnO}}_{3}$ is presented for x=0.21, 0.33, and 0.40. Pressure strongly d…
The effects of Bi/Ta and Sr/Ta mole ratios on ferroelectric properties of Sr x Bi y Ta 2 O z [ SBIT( x / y /2.0); 0.7≤ x ≤1.0, 2.0≤ y ≤2.6] thin-film capacitors were investigated. The SBIT films were grown by the sol-gel method using a spin-on coating on Pt/Ta/SiO 2 /Si and Pt/Ti/SiO 2 /Si substrates. The films were a…
The paper presents the state of the art in cements and concretes with alkaline-activated slag. Characteristics and properties of these materials are given. Special emphasis is made on those scientific and technical aspects which remain unsolved and which, therefore, call for further research.
This article review the state of the art on the effect of the joint incorporation of fluorides and sulfates to the cement crudes. This incorporation may be carried out partially replacing the traditional crudes, thus obtaining a new cement produced with a considerable energy saving and with advantageous characteristic…
With the present study, the necessity of carrying out tests to select the most suitable restoration treatment is remarked. Showing how the results obtained evidence the products behaviour, although knowing and evaluating limitations due to laboratory tests, different to real conditions.
The characteristics related to water absorption of some important stones very used in the southern of Spain were tested before and after the application of diverse commercial protective treatments, including the application of diverse dilutions and the correlative application of two complementary products. Some consid…
The weight increases of nylon-6,6 and glass-filled nylon-6,6 after 120 days exposure at 100% and 43% relative humidities were measured. The resultant mechanical properties of nylons were evaluated. Moisture absorption was seen to affect several mechanical properties. Specifically, an increase in moisture absorption re…
