Introduction The extensive research on optical glass materials had been done to produce the high optical ability in glass materials for optoelectronics applications.
Zinc oxide: Outstanding materials to reduce the melting temperature and may act as former glass The introduction of rare earth oxides as dopants in glass materials had been widely investigated.
Erbium oxide are the well-known dopant which had been used in many glass materials.
The optical absorption study in glass materials is crucial to relate with the theory of electronic structure of amorphous materials.

Besides stone, building materials of Mount Lu villas also include metal tile, flashing, brick
(1) Stone In the selection of building materials in the west and China, in addition to natural factors, more importantly, different culture and ideas matter.
It is worth mentioning that roof materials of the church are different from other villas, for most villas in Mount Lu, their roofs are made of metal materials, while 2 roof slopes of the No. 283 church are made of small bluestones which are from the south of Mount Lu.
Analysis of building materials used in key parts of villas in the Mount Lu (1) Base It is also called foundation.
Cross hollow masonry structure of these materials cover the above space, enclose the walls and support the roof.

Materials property measurement is needed on deformation, fracture and fatigue in hydrogen-containing media.
At the same time, there is a problem in technological support for evaluation of hydrogen compatibility of materials in laboratory conditions for evaluation of hydrogen embrittlement, depending on hydrogen concentration, methods and modes of loading, temperature, pressure and actual properties of materials.
Evaluation of materials for hydrogen pipelines can be carried out in accordance with the accepted provisions of IGC Doc 121/14, ASME B31.12 and ASME BPVC.VIII.3 (article KD-10) standards.

The material development is aimed at utilizing a suitable Metal Alloy in combination with a most appropriate plastic material considering the achievement of desirable basic features of Smart materials like Shape Memory Effect, Flexibility, recovery time etc.
INTRODUCTION Shape memory alloys are smart materials, remembering their original, cold-forged shape; possessing a tendency of returning to the pre-deformed shape when heated or by providing electrical connectivity [1].
These materials were usually light weight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems [2,3].
The recent developments and advancements in the Engineering sector urge for application of smart materials [Shape Memory Composites] in intelligent parts and control systems of Aerospace / automotive sectors [5].

Producing new composite materials.
The composite materials are the compound of two or more different nature materials, then obtain the new materials with excellent performance.
The composite technology of timber and other raw materials has matured, so it is feasible to produce new composite materials by using deserted wood furniture materials and other materials, such as wood-metal composites, wood-plastic composites and other new composite materials.
