Usually, owing to the work function of noble metals nanoparticles is larger than that of traditional semiconductor materials, A point of view, the charge distribution is readjusted for equilibration of Fermi level between the two materials, which result in the elevation of the noble metals nanoparticles Fermi level and the formation of Schottky barrier at the junction between the two materials [33-35].

Introduction Composite fabrication by using waste materials has gained much attention in recent years.
Waste materials originating from natural fibres such as sago, sisal, short silk fibre, oil palm empty fruit bunch, rice husk ash, jute fibre, rubber wood powder, jute, hemp, sisal, cotton stalk, kenaf, sugarcane banana fibers and other cellulosic fibres are used widely as reinforcement materials in various waste polymeric materials[1-2].
Polypropylene based materials are known to attract attention due to their good ability in balancing properties when mixed with soft rubbery materials [9].
Materials and preparation of composite The materials used in this study were PP homopolymer, NBR recycled product from mechanically ground used surgical gloves and RHP were grounded to 130-300 µm prior to usage.

Introduction For the advantages of the raw soil building, such as available local materials, adaptation to local conditions, simple technology, low cost and good thermal insulation properties, it is widely constructed in the majority of towns and villages in western China, especially in the remote mountain areas.
The adobes of test were from Luquan County, Yunnan Province, which were made by local craftsman, using local skill and local materials.
The modified adobes of test were from Yunnan Province, which were made by local craftsman, using local skill and local materials.
The main experimental materials are soil and bamboo, which are both from Song Ming.

When spring specific pressure increases, the highest temperature value of static ring exceeds the material temperature limit, and the zone exceeding the material temperature limit is bigger and bigger.
Therefore, some improvement measures are put forward regarding the surface materials sealing structure and environment temperature for corrugated pipe and seal. 3.1 Improvement of seal face material As for the static ring material, some high temperature limit sealing material is recommend such as fine graphite and silicon carbide materials to improve its performance and ensure the long-term good operation of machine seals. 3.2 Improvement of the environment temperature A cooling system can be designed in the ring inside to reduce the temperature of the friction surface.

A constant adjustable force Fs was superimposed to eliminate tube sagging due to large thermal expansion coefficient of polymeric materials at the processing temperature and create axial stress on the polymeric micro tube (Fig. 1).
Due to strain rate influence on the forming behavior of polymeric materials, the test device was designed to enable an adjustable velocity of pressure increase via the piezo valve.
The forming trials of the demonstrator were conducted with two different polymeric materials; PA6 and PET.
