  • Mass transfer in the multiphase multicomponent systems represents one of the most important problems to be solved in chemical technology, both in theoretical as well as practical point of view. In libraries all over the world, many books and articles can be found related to the mass transfer. Practically, all textbooks devoted to the separation processes or reaction engineering contain chapters describing the basic principles of the mass (and heat) transfer.

  • Hydrogen and synthesis gas (syngas) are indispensable in chemical, oil, and energy industries. They are important building blocks and serve as feedstocks for the production of chemicals such as ammonia and methanol. Hydrogen is used in petroleum refi neries to produce clean transportation fuels, and its consumption is expected to increase dramatically in the near future as refi ners need to process increasingly heavier and sour crudes.

  • It is interesting to look at the major sources of waste from within the chemical industry. Bulk chemical production is normally thought of as a ‘dirty’ industry and historically this has been the case. As the industry became more competitive, more economic processes needed to be developed and it became unacceptable (and non- viable) to produce the same amount of waste as 30 years ago. Today it is the speciality and pharmaceutical industries which produce most waste (at least...

  • Many of the techniques that have been developed have already been used to study the extent and distribution of variation in species gene-pools and to investigate evolutionary and taxonomic relationships among plant populations. With the development of the polymerase chain reaction (PCR) based techniques, in particular, numerous molecular technologies have been, and still are being, developed, which can be used for the detection, characterization, and evaluation of genetic diversity in plant populations.

  • VNU Journal of Science, Natural Sciences and Technology 26 (2010) 161-164 Fresh leaves of Litsea glutinosa (Lour.) C. B. Rob. from Ha Tinh were steam distilled to produce an oil in 0.15% yield. The essential oil was analysis by a combination of capillary GC and GC/MS. Seventy eight compounds were detected in the oil, of which more than 95.18% were terpenoids. The major components were (E)-β-ocimene (13.35%), β-caryophyllene (27.20%) and bicyclogermacrene (18.16%).

  • The Chemical Weapons Convention requires, among other things, that the signatories to the convention--which includes the United States--destroy by April 29, 2007, or as soon possible thereafter, any chemical warfare materiel that has been recovered from sites where it has been buried once discovered. For several years the United States and several other countries have been developing and using technologies to dispose of this non-stockpile materiel. To determine whether international efforts have resulted in technologies that would benefit the U.S. program, the U.S.
