Introduction
As the most widely used ferroelectric material, BaTiO3 has been studied for several decades.
Organic compound BTOT was selected as starting material.
Thus, more homogenous reaction enviroment and higher concentration of source materials could be expected.
Another important factor related to synthesis of nanoparticles in supercritical water could be attributed to corrosion of reactor materials.

Abstract: Taking modified na-bentonite as matrix, PEG-20000 and NaHA are added to form composite briquette binder, while its influence on the properties of the prepared briquette is studied.
In this paper, taking bentonite as the main inorganic binder, compounding different organic materials, composite briquette binder is prepared by taking advantage of water-swelling, adhesive property and adsorbability of bentonite which can facilitate the binding of the cola powder, improve the thermal stability, mechanic strength, pressure resistance of the briquette.
Experiment Materials.The coal sample was the anthracite coal produced by Longmang Coal Factoryin Yanbian County, Panzhihua City, and was smashed into particles with diameter of 1-3mm.
The infrared spectrograms of different composite briquette binders reveal that the composite of bentonite with all the organic materials retains the original characteristic groups such as-OH, -COOH and -NH2.
Under certain pressure of molding, it can bind the coal material to endow the coal with initial strength.

Introduction Controlled synthesis of higher ordered inorganic materials with specific size, shape, orientation, organization, complex form, and hierarchy has attracted a lot of interests owing to the importance and potential to design new materials and devices in various fields such as catalysis, medicine, electronics, ceramics, pigments, and cosmetics [1-10].
Biological systems are able to generate crystalline materials (e.g., seashells, born, teeth, and many others) with complex morphologies and specific functions at ambient temperature via biomineralization, and biomineralization process is elaborately controlled by some biomacromolecules such as proteins and polysaccharides as crystal growth modifiers [11,12].
The strategy of using organic templates or modifiers with complex functional patterns to control the nucleation, growth, and alignment of inorganic crystals has been widely adapted for the biomimetic synthesis of inorganic materials with complex form.

Introduction to Landslides
Landslide disasters occur when a mixture of geological materials (e.g., mud, sand, gravel, and rock) and water generate a flow movement as a result of gravitational force.
When rainwater flows into the ground, it scours and erodes geological materials on the land surface downward to a low-lying position.
In addition, rainwater not only saturates and accumulates geological materials and debris in valleys, but also causes an excessive amount of underground water to surface from the discontinuous side of the valley floor.
However, only using the size of slope angle θ to determine the occurrence of landslides is insufficient, because the material composition and vegetation condition of the accumulation layer are also key factors influencing such landslide occurrences.
