The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal.
Now the resist height upon developing must be calibrated to UV exposure energy, from which the optical
density of the device features in the mask may be determined. To this end, the resist height that results
from an optimized lithography process was calibrated with a range of optical densities from a reference
mask. From this information, the device height profile is encoded into the optical density profile
necessary to produce it.
The book “Holograms –Recording Materials and Applications” comprises five sections.
The first section has eight chapters on holographic recording materials including ionic
liquids in photopolymerisable materials (Chapter 1), Norland optical adhesive 65® as
holographic material (Chapter 2), porous glass and polymer nanocomposite (Chapter 3),
amorphous chalcogenide films (Chaper 4), azo-dye containing materials (Chapter 5 and
6) and photochromic materials (Chapter 7 and 8). The remaining four sections are
dedicated to a variety of holographic applications....
The current book contains twenty-two chapters and is divided into three sections. Section I consists of nine chapters which discuss synthesis through innovative as well as modified conventional techniques of certain advanced ceramics (e.g. target materials, high strength porous ceramics, optical and thermo-luminescent ceramics, ceramic powders and fibers) and their characterization using a combination of well known and advanced techniques.
