The red mud sintered bricks have good mechanical properties.
Tsakiridis [4] draw a conclusion that adding red mud would not affect properties of sintered bricks through a comparative experiments using a common ingredients and a gal 3.5% red mud materials.
However, red mud sintered brick failed to be industrialized in China, which still needs further work. 3.1.2 Subgrade materials Red mud has certain cementious properties and price advantage, commonly be used as subgrade materials.
SiO2, CaO, Na2O,A12O3, Fe2O3, TiO2, K2O, alkali components and trace other non-ferrous metal in red mud make the plastic products with addition of red mud have good anti-aging properties.
Conclusions Comprehensive utilization of red mud is a very important and urgent problem, though years of research has made some successful application, but most of the research failed to achieve industrial application because of economic factors, especially Bayer red mud.

The sustainable carrying capacity of the “tourism environment” is “influenced” by many factors, including “economic, natural, and social” aspects.
These papers emphasize the importance of considering multiple dimensions of sustainability, including ecological, social, and economic factors, when evaluating technologies or alternatives.
These efforts require a comprehensive understanding of the contributing factors and potential barriers to achieving clean energy objectives.
These factors are crucial in decreasing “greenhouse gas emissions,” promoting resource efficiency, and “mitigating climate change.”

Introduction Owing to the high mechanical properties and the good weld ability, low cost et al, aluminum-magnesium alloy have a wide application in aviation, shipbuilding, nuclear industry and weapons [1].
However, aluminum-magnesium alloys are non-heat treatable alloys, the micro alloying and hardening are the main methods to improve the properties of these alloys [2].
The results showed that added of element erbium can well improve not only the strength, plasticity, but also the corrosion resistance and fatigue properties of the alloys [6-8].
Deformation temperature is an important factor which will affect the flow stress.

In addition, due to the operation of the soil heat exchanger pipe, the geomechanical and temperature factors that cause its deformation are affected by the operation [18].
They provide cogeneration of electricity, thermal and mechanical energy.
In systems of soil heat exchangers, the amount of received heat energy depends on the speed, pressure, type of fluid circulating in the system, its physical properties, the number of soil pipes, the distribution of temperatures in the soil, the characteristics of the heat transfer process, which affects the temperature of the heat carrier, from which in turn, the temperature of the coolant at the outlet of the soil heat exchanger depends.
This affects the increase in the capacity of the heat pump plant as a whole, while reducing costs.
Construction of a geosystem with the selection of heat from dumps will make it possible to autonomously provide electric, thermal and mechanical energy settlements located around mines.

Geopolymer is significantly different from ordinary Portland cement in terms of structural properties and reaction mechanism [4].
Through the analysis of the infrared spectrum, it can be concluded that the heavy metal ions contained in MSWI fly ash will not affect the [SiO4] and [AlO4] tetrahedral structure, but be participated in the actual reaction in some form.

Introduction The performance of turbines is governed by the properties of nickel-base superalloys, which can sustain severe thermal and mechanical stresses under extreme environmental conditions.
A major progress in alloy chemistry is marked by the addition of Re, which promotes higher tensile strength, as well as better creep properties [1-3].
The influence of Re on thermophysical properties decreases after heat treatment.
In contrast to the negligible effect of thermophysical properties, a major influence of Re and Ru on the γ/γ’-microstructure can be found.
Thus, the γ’-size in Astra1-alloys with additions of 2 at.-% Re is possibly too small to obtain optimized creep properties.

This introduces a new dimension to metrology – in terms of higher effectiveness of measurements, higher credibility, a better understanding of the surface and new discoveries which help engineers create new materials with better properties and parameters [3].
Sq has similar properties to parameter Sa, however, it is more susceptible to single elevations and cavities.
Sp and Sv characterise load-carrying properties and accumulation of a lubricant.
Parameter Sz is a measure of average roughness and is applied where single elevations of surface do not affect the interacting materials.
All parameters selected for the analysis exhibit an impact on the operational properties of the surface and on the possibility of independent control during the surface shaping process.

., Japan) were studied to determine mechanical properties, volume change ratio, and force generation characteristics of the PAN gel fibers for both chemically-driven and electrically-driven systems [4], no systematic studies for the as-spun PAN fibers and the PAN gel fibers was performed.
Morphology of the as-spun PAN fibers prior to the activation of the PAN gel fibers and chemomechanical properties of the PAN gel fibers, the subject of this study, were carried out to evaluate the effects of experimental parameters on morphology of the as-spun fibers and the influence of pH sensitivity on dimensional change of the PAN gel fibers.
Results and discussion The properties of different concentrations of polymer solutions are given in Table 1.
Properties of the PAN/ DMF solution Spherical or spindle-type beads were observed for the electrospun fibers at viscosities ranging from 46 to 1000 cP (PAN concentrations from 4 to 9 wt%).
It is reported that viscosity and surface tension of the precursor solution affect the formation of beads.

Lead zirconate titanate (PZT) is a suitable material for ultrasonic transducers because of its high piezoelectric constant, relative permittivity and electromechanical coupling factor [1].
Using these test features, properties of the PZT thick film single element devices in terms of electrode feature and size were examined.
The sintering aid helps to increase the density and piezoelectric properties of the sintered PZT film.
Applied voltage and flow rate are major factors that affect the characteristics of atomization mode and deposition result.
Other properties such as resonant frequency and acoustic response of these PZT elements are suggested to be examined after etching Si back substrate.

Many investigations were devoted to microstructure modifications of titanium caused by cold rolling and its influence on resulting material properties.
The latter mechanism affects microstructure, strain hardening, texture evolution and residual stress.
