Introduction Materials that possess both magnetic and electrical properties have drawn much attention in recent years because of their potential use in novel devices in which magnetic and electric properties can be mutually controlled [1].
The stoichiometric amounts of the starting materials, Bi2O3 (with 5 mol% excess), Fe2O3, MnO2, BaCO3, and TiO2.
A few trace of minor impurity phase of Bi2Fe4O9 was observed, which might be attributed to the volatilization of Bi in the sintering process and the uneven mixing of starting materials.

In particular Soft Condensed Matter Sensor (SCMS) fibers are a promising class of materials, which to provide flexible sensor and microelectronic structures for body-mounted wearable computing applications.
The SCMS fibers are soft, flexible, and their sensor behavior can be tailored by the use of different inorganic materials [1-7].

The use of soft soil Shallow Large Span Tunnel and the Urban Design Study Cave + CRD method, that is, first excavated in the hole, and then has two main tunnel excavation outside the three-hole lead, followed successively by the main tunnel excavation in the left lane the inside wall of the three-hole lead, finally has the right line of the main tunnel excavation by construction technology inside the walls of the three-hole lead, materials and energy savings, effectively control costs and maximize social and economic benefits.
Beam overall state of compression, bending moment is small, in line with the theoretical analysis of the law, but its material properties play a limited, in contrast to shot Crete stress state, the proposed design phase should be appropriately reduced beam model, increasing jet concrete thickness, material properties, and give full play to project cost savings.

Based on the general regularities of β-C2S and α’-C2S interaction with aluminate solutions, one could expect the influence of structural features of different types of sinters based on various alkali-aluminate raw materials on silica transition into aluminate solutions.
Due to the disordered structure of α’-C2S (high content of small particles, fragments), a high level of oversaturation of SiO2 in the solution quickly occurs with respect to the metastable equilibrium of Na2O – Al2O3 – SiO2 – H2O, similar to how, for example, oversaturation with SiO2 in an alumina solution occurs when it interacts with active forms of silicon containing materials - hydrargillite bauxite, silicicic acid [2, 3].
At the rapid creation of significant oversaturation with SiO2 in the alumina solution (due to the active silicon-containing materials) unstable in this range of concentrations of bonds [Al - O - Si] may occur, which lead to the formation of alumina-silicon associates (sodium hydroaluminosilicate prototype) and crystallization of sodium hydroaluminosilicate, the system "eats" the excess silica and returns to the metastable state with the participation of simple hydrated silicon and aluminum ions.
