Clogging is mainly due to materials accumulation and the microbe growth within the substratum pores that caused remarkable reduction of hydraulic conductivity, then leads clogging.
Particle shape and material also influence the hydraulic conductivity.

Introduction Liquid crystal elastomers (LCE) are hybrid materials composed of liquid crystals (LC) and elastomers.
Elastomers are crosslinked polymer chains that have elastic properties and liquid crystals are mesogenic materials that have orientational order properties, so LCE have combination properties of both substances [1-5].

In order to study the anti-aging properties of polypropylene / mica composite materials, the above polypropylene / mica composite materials were placed outside to study the influence of natural aging time on the anti-aging properties and to explore the natural aging mechanism of polypropylene / mica composites.
Natural aging research results show that:with the extension of the natural aging time the surface of materials will appear cracks and sheddings.
Preparation of composite materials.

An End-Type Fiber-Optic UV Sensor Covered with Mixture of Two UV Sensitive Materials Ana V.
The assumption is that fluorescence phenomena could be noticed when some UV sensitive materials are deposited on optical fiber tip.
By creating multiple sensor regions, each covered with different UV sensitive materials, we can define exactly which part of the sensor is exposed to UV radiation and in what amount.
Furthermore, by using materials that react to different bands of UV radiation, we can determine the presence and intensity of the UV radiation in the specific bands (i.e.
By using various UV sensitive materials option of multipoint and distributed measurement of UV radiation over single fiber link is enabled.

Recently a number of aluminum alloy materials have been researched on the flow stress behavior using thermal-mechanical simulator and other test equipment [1, 2].
The experimental procedure and calculation method can be applied to other alloy materials developing constitutive equation, predicting the mechanical behavior and providing the material model for the FEA simulations.

In fact, majority of today’s mechanical parts are made of metal materials, most of the metal materials are magnetoconductive.
Their experimental results suggest that MR jet can efficiently correct surface figure error to high precision, with less than 30nm peak to valley error and micro roughness of less than 1nm rms on a number of materials [6, 7].

Introduction A renewable natural organic fibers act as reinforcing materials which are biodegradable and ecofriendly for the use of glass or carbon fiber and inorganic fillers.
It should be noted that the percentage of water absorption increased generally when more reinforcement materials are used which can be attributed to the hydrophilic nature of lignocellulose materials.
