Photography modem

From this period onwards, the technique was used as a qualitative method, firstly via a visual observation with a spectroscope and later via photography. Modem quantitative methods only date from 1925 when good optical equipment came on the market. 

Studies of surfaces and surface properties can be traced to the early 1800s [1]. Processes that involved surfaces and surface chemistry, such as heterogeneous catalysis and Daguerre photography, were first discovered at that time. Since then, there has been a continual interest in catalysis, corrosion and other chemical reactions that involve surfaces. The modem era of surface science began in the late 1950s, when instmmentation that could be used to investigate surface processes on the molecular level started to become available.

This chapter is concerned with dyes and pigments which are complexes of azo, formazan, azomethine, nitroso, anthraquinone and phthalocyanine ligands. Many of these compounds find important applications in other fields, particularly colour photography and reprography, analysis, catalysis, biology, and some modem high technology industries such as electronics. These applications are described in other chapters of this volume.

The use of photography in the 100 to 1000 nm spectral region has a long tradition in spectroscopy but is rarely used in modem instruments because of its low sensitivity and slow readout time with respect to most other photon detectors. We shall give no discussion of photography, as most of the techniques required for routine work are well known or are given in instractions supplied with commercial photographic materials. ... 

The development of new and improved dyes based on pyrazolinone structures has likewise led to modem developments of no inconsiderable magnitude. The use of tartrazine as an approved color for foodstuffs is of significance. The development of pyrazolinone dyes for use as magenta couplers and sensitizers in color photography and in metal chelate dye structures has established a renewed, modem interest in these dyes. The chelating characteristics, which will be of continuing theoretical structure interest in coordination chemistry, have been used in developing picrolonates (salts of 3-methyl-4-nitro-l-p-nitrophenyl-2-pyrazolin-5-one) of possible utility in analytical procedures. 

Today, almost all international museums and galleries possess collections which contain plastics. Plastics may be identified within building materials, defence equipment, ethnography, furniture, housewares, information technology, medical and sports equipment, modem art, photography and toys. Many combine metals, textiles and wood with plastics in their construction. In addition to the objects themselves, many of the materials used to store, transport and display them are also plastics. While museums continue their policy to collect objects that reflect both everyday life and historical events, the proportion of plastics in museums will increase.
