Isothiocyanates (ICTs) are a group of molecules that can be used for many different purposes, they exhibit anticancer, antimicrobial, antibiotic, and anti-inflammatory properties. The synthesis of isothiocyanates has been a focus of many researchers for nearly the past 100 years. One of the most common synthetic methods is to form a dithiocarbamate salt, either as the first step or in situ, and then treat the salt with a desulfurization agent to reach the isothiocyanate. There are many different desulfurization agents available. Among these, there are eleven in particular that will be discussed in this short review, namely thiophosgene, lead nitrate, ethyl chloroformate, hydrogen peroxide, triphosgene, iodine, cobalt, copper, sodium persulfate, claycop, and tosyl­ chloride. There are four additional particular methodologies that stand out from the literature available on this topic that will be covered, namely the production of isothiocyanates from hydroximoyl chlorides, via elemental sulfur, microwave-assisted synthesis, and through the tandem Staudinger/aza-Wittig reactions.1 Introduction1.1 Metabolism of Glucosinolates2 Synthesis of Isothiocyanates2.1 Isothiocyanates from the Decomposition of Dithiocarbamate Salts2.2 Isothiocyanates from Hydroximoyl Chlorides2.3 Isothiocyanates Produced via Elemental Sulfur2.4 Microwave-Assisted Synthesis of Isothiocyanates2.5 Isothiocyanates via the Tandem Staudinger/aza-Wittig Reactions3 Conclusion

Photochromic Materials

Microwave chemistry involves the application of microwave radiation to chemical reactions and has played an important role in organic synthesis. Functional dyes are those with hi-tech applications and this chapter attempts to provide an overview of the recent developments in microwave-assisted synthesis of functional dyes. Emphasis has been paid to the microwave-assisted synthesis of dye molecules which are useful in hi-tech applications such as optoelectronics (dye-sensitized solar cells), photochromic materials, liquid crystal displays, newer emissive displays (organic-light emitting devices), electronic materials (organic semiconductors), imaging technologies (electrophotography viz., photocopying and laser printing), biomedical applications (fluorescent sensors and anticancer treatment such as photodynamic therapy). In this chapter, the advantages of microwaves as a source of energy for heating synthesis reactions have been demonstrated. The use of microwaves to functional dyes is a paradigm shift in dye chemistry. Until recently most academic laboratories did not practice this technique in the synthesis of such functional dyes but many reports are being appeared in the journals of high repute.

Its been long recognized that various economies of the world are interlinked through international trade. The experience of the past several years, however, has demonstrated that this economic interdependence is far greater than was previously realized. In this context, the importance of international economic theory as an area distinct from general economics hardly needs any mentioning. What gives international economic theory this distinction is international markets for some goods and effects of national sovereignty on the character of economic activity. Wilfred Ethier's book, which incorporates recent developments in the field, is an excellent addition to textbooks on international economics for one- or twosemester undergraduate courses. The book mostly covers standard topics. A distinguishing feature of this book is its detailed analysis of the flexible exchange rates and a discussion of the various approaches used for their determination. Within each chapter, the author has extensively used facts, figures and major events to clarify the concepts in the light of the theoretical framework. The book also discusses, in a fair amount of detail, the existing international monetary system and the role of various international organizations.

Sugarcane Processing

Developments in the technology of production of sugar from sugarcane tend to be incremental improvements in an effort to reduce costs and boost revenue. Nonetheless the developments are significant and contribute to sustainable sugarcane enterprises. Some technologies have adapted to changing environmental conditions, and more attention is being given to boosting revenue through associated activities, particularly in enhancing the potential for sugarcane operations to exploit the energy value of sugarcane. This paper outlines recent developments of interest in processing sugarcane.
