Specific topics include, but are not limited to: PVD and CVD processes, nanostructured and nanoparticles synthesis, thermal barrier coatings, biomedical coatings, functional coatings for electronic, optical and magnetic applications, surface modification by plasma, ion and laser beam techniques, direct fabricated materials, coatings for space, automobile and environmental industries, corrosion and oxidation resistance coatings, modeling, mechanical and tribological properties, interface properties and adhesion, advanced surface investigation techniques, ultrahard coatings.

SYMPOSIUM: Superalloys and Coatings for High Temperature Applications
This symposium will provide a forum for the discussion of: (i) the degradation mechanisms which occur in superalloys, including oxidation and corrosion, and their effect on mechanical properties (ii) coatings for the superalloys, including overlays and thermal barrier systems, and (iii) issues concerning the compatibility of superalloys with coatings, particularly bond coat technologies.

SYMPOSIUM: Texture and Microstructure in Thin Films and Coatings
PROCEEDINGS: Journal of Electronic Materials
This symposium aims to discuss specific issues of microstructure and crystallographic texture development and evolution in films and coatings. (Processing-structure and structure-properties relationships will be addressed in connection with structural evolution). The purpose of this symposium is to provide an opportunity for researchers in industry, laboratories, and academia to discuss relevant issues of processing of films and structural evolution in electronic and magnetic films. The problems of design of structure and texture in films for optimum properties and performance will be discussed. The presentations on coatings and surface modification methods to improve the high temperature oxidation resistance, wear, hardness, corrosion, thermal conductivity, and friction are also planned. A joint session with the symposium on Refractory Metals for Electronic Applications is planned.

SYMPOSIUM: Functional Thin Films for Sensors
PROCEEDINGS: Journal of Electronic Materials
Functionalized thin films for various sensing applications are attracting growing interest due to their fascinating properties and unique behavior in various environments. The transduction schemes for these new materials often involve new chemical and physical phenomena associated with size confinement, microstructure, phase domain distribution, and etc. Some examples include quantized excitation or emission, metal-insulator transition, nonlinear optical properties, very high gas adsorption rates, chemical and physical selectivity. The ability to controllably synthesize these thin film structures is key to advancing sensor science and technology (e.g., gas sensors, chemical sensors, light detectors, non invasive sensors). Functional thin films are readily incorporated in prototypes and devices demonstrating performance far exceeding that of existing sensor products. Multi-parameter porous silicon sensors, metal ion sensors based on self-assembled monolayers and uncooled IR thin film detectors are noteworthy examples of such devices. The development of economically viable and practically useful functional thin films requires a great deal of inventiveness and creativity. This symposium aims to foster such activities by providing opportunities for intensive discussions and exchange of ideas. Multiple sessions, each having a specific topic, are planned. These topics will include:

• The physics and applications of sensor thin films (gas sensing, chemical sensing, optical sensors, magnetic sensors, etc.)
• Chemical methods for synthesizing functional thin films for sensors
• Self assembly
• New concepts for thin films electronic, photonic, and magnetic structures and devices.

SYMPOSIUM: Photonic Processing, Process Monitoring, and Diagnostics
The purpose of the symposium is to provide a forum for the representation of current activities and new ideas in the general area of photonic processing of materials and process monitoring using phonic devices. Papers will address (a) the new application of conventional processes, (b) new, more efficient technologies (c) numerical methods for the design of these processes. Papers on experimental studies that can support the advancement of analytical methods are also planned. Typical topics may include laser surface processing, infrared processing, optoelectronic devices, ultrafast processing of thin films, infrared imaging, laser systems for process monitoring, and diagnostics based on photonic sensors. In addition to theoretical studies, experimental efforts that generate data to validate the models are encouraged; as are applications of these techniques to solve relevant problems, especially by industrial investigators.

Materials ⇔ Applications
The connections between materials science and engineering often occur when materials are developed for specific applications. Exploring and understanding the diversity of materials development approaches and complexity in end use requirements provides TMS Annual Meeting attendees with useful knowledge that can be applied to their specific areas of responsibility. In 2005 a wide range of programming will be presented in this area with the themes of:

• Transportation
• Emerging Materials
• Electronic Materials
• Other Application Areas
