Due to their high strength, exceptionally good fracture toughness and wear, corrosion as well as fatigue resistance, maraging steels are considered as important materials for space, military, automobile, tooling and other commercial applications.
Materials Methods Hot rolled conventional maraging steel was obtained from M/s Bharat Aerospace, Mumbai, India.

Very pure nano-scale materials when reaction occurs in the gas phase, far from polluting walls, may be prepared.
Iron-based materials have a huge number of applications: magnetic storage media, sensors, catalysts etc.
The doping of γ-Fe2O3 (maghemite) has attracted attention because of its applications in magnetic recording tape materials.

Mat Science and Appl.
At longer carrier decay times, multiple trapping events dominate that can be described by a stretched exponent approach, typical of disordered materials.
This implies a need for the materials characterization of thin semiconductor layers.
In case MOSFETs are available on an SOI substrate, several device-based techniques have been developed for materials' characterization [2].
A detailed analysis reveals that the asymptotic carrier decay is composed of multiple trapping events that can be described in a similar way as for disordered materials [1].

Collecting and measuring trace hazardous vapors requires both universal and chemically-selective sorbing materials.
We coat SAW devices, operating at 97 MHz, with four different polymer materials and NPC for comparison.
Such chemical discrimination is an excellent property for SAW sensor coating materials.

The materials shall be combined with a very light planking of ultrathin plastic panels as well as steel- and aluminum sheets.
The reason mainly can be seen in the different materials used.
On the other hand several manufacturing processes and varying materials are used for body components.
The project pursued a holistic approach including the entire life cycle from disassembly-friendly design of the batteries to the production of new active materials from recycled raw materials.
