Y-doped barium cerate-zirconate (BCZY) ceramic oxide is proven to be a competent material as an electrolyte with high proton conductivity as well as chemical and mechanical stabilities in CO2 and H2O atmospheres.
Introduction Chemical composition and microstructural parameters of a material are taken as two major factors that will affect the protonic conductivity of polycrystalline solid oxide electrolytes.
Owing the ability to self-organize in solution, surfactant can modify the interfacial property and enhanced the compatibility between particles of different characteristics [5].
Surfactant affects the phase formation of BCZY ceramic powder as well as its morphology.

Both hydrophilic and hydrophobic pores of different size are available for an inorganic modifier that is able to affect functional properties of the polymer.
In the framework of the approach [95], embedding of particles into ion exchange polymer is determined by a number of factors.
The influence of these factors is analyzed in [95].

Functional properties of nanophase materials are different from conventional materials, which determined the related technology for the rapid development and wide application space.
The characteristics of nanophase materials are different from conventional materials in function, which is the key factor for its rapid development of correlative technology and its widely application.
All the data tell us that the CaCo3 monofilament fibers are better than domestic product in the tensile strength, elongation and shrinkage properties.
Nanophase material with high specific surface area of the nanometer particles can be easily adsorbed by the textile surface, and coating with nanometer material does not affect the fabric air permeability and handle feel.
The textile can store energy, while retaining the mechanical properties.

Abstract.
Video Encoding Optimization Based on DSP 2.1 Optimization of storage complexity Memory one of the main factors of the system overhead (chip area, power consumption, hardware costs, etc.), reducing the storage capacity is critical for the system.
Software pipelining is an instruction for the arrangement cycle operation mode within the technical, scheduling cycle instruction, making the loop iterations in parallel implementation. 3.2 Optimization result The purpose of video transmission and storage is to ensure the validity and reliability, requires coding to compress video image data as much as possible the amount of bandwidth and storage space to meet the objective constraints, but also consider other factors, Such as the coding delay, distortion (quality), coding complexity and fault-tolerant properties.
l Control flow instruction Flow control commands (if, switch, do, for, while) will lead to warp threads branch block, thus affecting the effective instruction throughput, will lead to different paths of execution threads.

Two-diameter piston push centrifuge is suitable to refined cotton dewatering as refined cotton and nitrocotton have similar properties, namely, they belong to fiber, and need continuous dewatering and washing.
It’s because refined cotton has such properties as wonderful hydrophilicity, good absorption [4], light slurry concentration and short fiber, etc.
Slurry concentration is a vital factor, which concerns whether piston push centrifuge can work properly and its production capacity.
Screen is the important component of piston push centrifuge, affects centrifuge separation effect and operability directly.

If the maximum stress should get to the outer surface anyhow, the fillet radius should be so small, that the final notch factor would not allow the experimenters to claim the specimen to be unnotched.

A significant objective in secondary Al manufacturing is to achieve enhanced sustainability through combined mechanical and thermal processing for improved properties giving reduced mass and longer life along with decreased processing steps, energy consumption and pollution.
TMP always involves a mechanical shaping operation that must successfully create the shape and impart a structure leading to the specified mechanical properties.
DMB develop directional properties (texture) that depend on the method of mechanical shaping, being little affected by T in deformation.
Almost every process combination has instances of marked improvement of selected properties; however, it is not necessarily applicable to other alloys.
