Ceramic engines do not require a cooling system and hence allow a major weight reduction and therefore greater fuel efficiency.

The total surface area, As, external surface area, Aext, and the pore volume, Vp, were estimated
from the corresponding αs plots, constructed using standard data for adsorption of nitrogen on nonporous
partially hydroxylated silica [31].
in the case of the pure silica sample, Si18, and on the Ti-MCM-41 sample with the lower Ti content, TiEp18-100, there occurred reductions of pore volume, Vp, of 23% and 18%, respectively, whereas for the Ti-MCM-41 samples with higher metal contents, TiEp18-50 and TiEp18-10, the decreases in pore volume observed, namely 9% and 5%, are almost negligible.

Introduction
Spintronics has a promising future for the development of the next generation of information technology due to its superior data transfer and energy consumption characteristics.
Fig. 9 displays the reduction of Eg in the tensile strain from 1.63 eV in Sb = +3% to 1.5 eV in Sb = +6%.

The results show that the regression model is in good agreement with the experimental data, the prediction accuracy is high, and the model can be used for further analysis and optimization.
When the water-cement ratio is too small, the cementitious material cannot be fully hydrated, the cementitious slurry mobility is poor, cannot be fully wrapped with coarse aggregate, resulting in a reduction in the bonding strength of aggregates, and produce more pores and thus cause a decline in the compressive strength; when the water-cement ratio is too large, the cementitious slurry mobility is too large, cannot be uniformly wrapped with coarse aggregates, and some of the cementitious slurry sinks to the bottom of the specimen, which results in a difference in the overall strength of the structure of the specimen, which leads to the decline in the compressive strength.

Our numerical simulations are compared to various numerical and experimental data presented [19-22] and summarised in Table 1.
The increases in mass flux (reduction in pressure drop) due to the crack induced a relative drying region owing to the macrocrack flow enhancement and exchanges with the surrounding porous medium.

They use material performance parameters, repairing pipe diameter and corrosion pore size data, etc.
Along with the progress of the composites industry technology, the expansion of the scale of production, and reduction of the production cost, composite materials application should further expanded in the field of pipeline repair [14].

Natural pigments were identified as a potential alternative sensitizer dye for DSSC due to its simplicity of preparation, relatively inexpensive, complete biodegradation, ease of access, purity grade, environmentally friendly, and, most pertinently, a significant reduction in use of noble metal and cost of chemical synthesis [29–31].
To understand data collected from electrochemical impedance spectroscopy, a number of equivalent circuits have been developed.
