Ag nanoparticles were obtained by the microwave solvolthermal method using silver nitrate, PVP and ethanol as raw materials.
The functional performance of CeO2 materials is influenced by morphology and nanostructure which include the size, shape, and surface/volume ratio [7, 8].
Surface modification can improve the performance of semiconductor materials [10, 11].

Cellulosic aerogels as ultra-lightweight materials.

At present, this issue in domestic science, according to the authors, has not been studied enough.
Such materials as foamed polyethylene and expanded polystyrene meet these criteria. 2.

One of the promising directions is the development of industries based on the electrochemical processes that allow abandoning the use of chemical oxidants and reducing agents that greatly reduce or entirely eliminate the waste of mineral salts, more efficient use of raw materials and materials, which further enhances its practical value.
Nowadays, special attention is paid to non-equilibrium syntheses of functional metal oxide materials [10-12].

Introduction Quasi-brittle fracture is a failure characteristic for some important structural materials.
These are brittle materials that have some tolerance to damage and include concrete, polygranular graphite, ceramic-matrix composites, geological rocks and bio-medical materials.
The mechanical properties of engineering materials are usually characterized in uniaxial tension testing by applying quasi-static loads to standardized specimens.

A Study on Hydrocyclone with Rotating Blades on Overflow Pipe Wall Yung-Sheng Lai1, Chun-Wei Fu1, Chuan-Yi Pan1 and Rome-Ming Wu1,2,a 1Department of Chemical and Materials Engineering, Tamkang University, 151 Ying-chuan Road, Tamsui, Taipei County 25137, Taiwan 2Energy and Opto-Electronic Materials Research Center, Tamkang University, 151 Ying-chuan Road, Tamsui, Taipei County 25137, Taiwan aromeman@mail.tku.edu.tw Keywords: hydrocyclone, rotating blade, overflow, particle, separation Abstract.
There proposed a dual vortex finders in a three-product cyclone to prevent the short-circuiting of coarse material into the overflow and to promote preferential separation of the material reporting to the inner and outer overflow streams [5,6].
The blade height may be increased or lighter materials may be employed when the upper inlet pressure increases.

It was reported that fatigue damage of the roof material is scattered by thermal expansion exposed to solar radiation and wind load [1-3].
The influence of thermal expansion is also assumed to increase on steel roofing material used for gymnasiums and factories.
Effects of wind load subjected to steel claddings were reported, but influence of temperature load subjected to steel cladding fasteners and prediction of damage longevity in long span roof materials affected by thermal expansion also were reported [4,5].
