Structure of the solder was studied by an in-situ high energy X-ray diffraction experiment (energy of an X-ray photon: 60 keV) where 2D XRD patterns were collected from the sample in the temperature range from 298 K to 566 K.
Our main goal lies in a preparation of a lead-free solder with fine grain structure made exclusively of biocompatible elements.

The micrometric sized ZrO2 ceramics presented higher resistance in the artificial saliva than nanometric sized structures.
This causes internal stresses in the material structure, generating microcracks around the transformed particles.

Field performance monitoring and product ion tracking results showed: ①the indigenous microorganisms were activated with the number increased 2-3, and microbial population structure changed apparently; ②The content of CO2 and CH4 in the gas of oil well changed slightly; ③the properties formation water were changed, the content of HCO3- in formation water varied greatly, and emulsion were found. ④Although Indigenous Microbial Flooding Technology may be a potential technique for the development of oilfields, that biogas generated by microbes is not the primary mechanism of Indigenous Microbial Flooding Technology is determined.
Therefore, it was considered necessary to study the microbial population structure in the oilfield before the experiment.

Compatibilities between lithium bis(oxalate)borate-based electrolyte and LiFePO4, LiMn2O4 or LiNi0.5Mn1.5O4 cathodes for lithium-ion batteries Shiyou Lia,*, Jinliang Liub, Xiaoling Cuic and Liping Maod College of Petrochemical Technology, Lanzhou University of Technology, Lanzhou 730050, China a,*sylilw@163.com, b463057648@qq.com, cxlcuilw@163.com , dmaolp-861@126.com Keywords: Compatibility, Electrolyte, Lithium-ion batteries Abstract: Olivine-type LiFePO4 and crystal structure LiMn2O4 or LiNi0.5Mn1.5O4 are promising cathode materials for electric vehicles (EVs) applications.
Olivine-type LiFePO4 and crystal structure LiMn2O4 or LiNi0.5Mn1.5O4 have been attracted much attention for using in EVs, owing to their high energy density, thermal stability, environmental friendliness, and low raw materials cost [2-4].
And to make matters worse, the presence of HF has a detrimental impact on the surface chemistry of cathode materials especially at elevated temperature, which is a serious shortcoming for the calendar and cycle life in lithium-ion batteries [6-9].

HNTs have an interesting and extraordinary structure accompanied by a various exterior and interior lumen surface.
Thus, they could be categorised as green analytical chemistry.
Owing to the incorporation of TiO2 nanoparticles into the PLA matrix with a condensed chemical structure, the internal space network structure of the PLA polymer was demolished, producing a largely density reduction.
These increments could be attributed to the increasing of film hydrophilicities because of hydrophilicity TiO2 structure.
This could be attributed to the hydrophobic nature of TiO2 nano-ingredients which prohibited the water paths in the nanocomposites structure [6].

It was found that SiO2 thin films showed super hydrophilicity which could last long at Ar/O2 ratio of 6:4; under such condition, substrate temperature also affects hydrophilicity of films, the best of which can be obtained at 90 ℃. 0 Introduction In 1992, Kresge etc.[1] reported mesoporous silica with a special structure in Nature, its excellent properties caused a research boom on silica material.
