The utilization of the sludge from this mudflow as useful materials is a potential solution to this problem.
Some modifications in the treatment process to purify the solid product such as removal of carbon material prior to hydrothermal treatment or dissolution of quartz and other lower CEC materials with longer time of contact with alkali medium may increase the CEC of the product.
With higher concentration of alkali medium and hydrothermal treatment temperature, more quartz and other silica and alumina containing materials in the mud can be dissolved into the alkali medium and converted into zeolites during hydrothermal treatment process.

Introduction Hydrogen-assisted mechanical degradation of structural materials is one of the most complex phenomena of the metallic materials degradation, due to several new unknowns in the degradation process kinetics, compared to the degradation in the absence of hydrogen in metal.
Hydrogen may degrade the mechanical behavior of metallic materials, including steel, and lead them to failure.

To effectively detect the defects, the dispersion characteristics and multimode of guided waves in the plate are studied by the disperse simulation software, and the variation of dispersion curve is analyzed by the geometric parameters and materials of plate.
Fig.1 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 1mm Fig.2 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 2mm Fig.3 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 3mm Fig.4 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 4mm Material impact on Lamb wave dispersion curve Lamb wave dispersion curves for a plate of the same thickness have essential differences due to the difference in materials selecting, the density of the material, the longitudinal velocity and shear velocity of the guided wave propagation.
Lamb wave dispersion curves for a plate of the same thickness vary from each other due to the different physical characteristics of different materials.

SEM images illustrated highly ordered macroporous structure which was a characteristic for 3DOM materials.
These properties make 3DOM materials a great candidate as photodegradation catalytic application. [1] TiO2 is considered to be an important material for photocatalyst because due to its chemical stability, nontoxic, low cost and low band gap energy.

Introduction Nowadays, the development of new cast iron materials seems to offer greater competition with other materials and makes cast iron a competitor for components that are not traditionally made.
Materials and Methods The material investigated in this study is nodular cast iron.
