Latest developments and applications in glass science and technology
- 2. Amorphous, Hard, Brittle Transparent/ Translucent No definite melting point or structure Produced by fusion of silica, lime, potash or soda Super cooled liquid
- 3. Glass making nowadays is a modern and hi-tech industry. New chemical compositions and new development techniques have been initially investigated at small-scale. There have been many advancements in glass technology. Some of the advanced technologically important glass are:
- 4. Latest glass Sciences & Technologies Smart glass Vision security glasses Ultra Thin glass technology Colloidal glasses Polymer glasses Fiber glass Glass ceramics Gorilla glass Insulated glazing Nano channel Glass material Bio- active glass Self cleaning glass
- 5. Glass/ glazing whose light transmission properties are altered when voltage, light, or heat is applied. Generally, glass changes its property from transparent to translucent and vice versa. Electrochromic device Photochromic device Thermochromics device Suspended particles device Polymer dispersed crystal liquid device Devices related to technology used in Smart glass
- 6. Bioactive glasses are those that can provoke a specific beneficial biological response when implanted It forms an apatite-like layer on its surface after incubation in Simulated Body Fluid (SBF) Applications Bone regeneration Periodontics Dentistry implant Hemostatic agent Angiogenesis Nano carrier Co-drug delivery
- 7. Mechanism
- 8. GORILLA GLASS Made from Alkali- Aluminosilicate Resistant glasses Strong & Thin Alternative of plastics used in devices High flexibility Flexibility
- 9. NANO CHANNEL GLASS MATERIALS Alternate method for fabricating nanostructures Complex glass structures containing large numbers of parallel hollow channels High density of uniform channels with diameters from 15 micrometers to 15 nanometers Hollow channels are arranged in geometric arrays with packing densities as great as 1011 channels/cm2. Material for chromatographic columns, unidirectional conductors, Microchannel plate and nonlinear optical devices Masks for semiconductor development, including ion implantation, optical lithography, and reactive ion
- 10. Hydrophilic and photocatalytic coating on window that is activated using UV rays present in daylight Photocatalytic action breaks down organic dirt that lands on the surface of your windows, preventing anything from sticking to the glass. Working It is a specific type of glass with a surface that keeps itself free of dirt and grime.
- 11. Self cleaning window Self-cleaning solar panels Self-cleaning building facades Computer monitors and PDA screens APPLICATIONS
- 12. GLASS POLYMER Glass Polymer is an attractive and versatile material that can take packaging to another level of appearance. Moldable composite material Comprises short glass fibers in a matrix of a polymer material Used to manufacture wide range of structural components by injection or compressi on molding Ideal glass Alternative that offers design flexibility, chemical, durability, and chemical and shatter resistance CHARACTERISTICS
- 13. Polycrystalline material Production: Controlled crystallization of base glass Amorphous phase & crystalline phases Share properties with both glasses and ceramics. Key to a glass-ceramic material is controlling the nucleation and growth of crystals in the base glass Kitchen wares Military: high thermal and radar wave Medical: High strength bioactive materials Construction Heat exchanger in gas turbine engines APPLICATIONS
- 14. INSULATED GLAZING OF GLASS Two or more glass window panes separated by a vacuum or gas filled space Technical term for 'double glazing' and 'triple glazing' vacuum is designed to reduce heat transfer Glass thickness is equal between 3mm to 10mm APPLICATIONS Doors Window Refrigerator Vehicles Microwave
