Chemical fibres — An important factor in economic development

1997 set a record for the past 20 years in the growth rate of world production of chemical fibres and filaments. In comparison to 1996, this figure, was 11%, primarily due to synthetic fibres, where polyester fibres still occupy the leading position (approximately 15 million tons). Production of cellulose (viscose, acetate, cuprammonium) fibres and filaments dropped, especially for industrial applications. The greatest changes occurred in Asia and the Far East, whose share was more than 60% of world production of chemical fibres, and the growth rates were three times higher than in Western Europe. The volume of fibres produced in Eastern Europe and CIS countries, including Russia, as previously was far from the 1990 level, 3–6 times lower. China moved into first place among manufacturers of chemical fibres, with 860 industrial installations out of the 2000 operating in the world today. Polyester fibres and filaments predominantly developed, and their production volume is planned to increase to 2.5 million tons by the year 2000, and on the whole, production and consumption of these fibres in Asia for this period will exceed 80% of the total production volume of all synthetic fibres (except for polypropylene). High capacities are also characteristic of the countries in this region — 85% on average, while it is even higher in South Korea, Taiwan, and China, 90–95%. Of the new generation of chemical fibres, polypropylene fibres, which have moved into second position in the world, the highly elastic fibre Spandex, and the “Lyocell”, produced by ecologically clean technology, with a predicted industrial output of 300,000 tons/year by 2005, are developing rapidly. In world consumption of textile raw material for 1990–2000, the share of cotton has been continuously decreasing (from 48.7 to 42.2%), while the share of synthetic fibres is increasing (from 39 to 48.3%). The highest demand is for the latter so that the production capacity will increase to 31.5 million tons by 2000 and production could attain 25.4 million tons. The share of fibres for manufacture of clothing will decrease, while the proportion used in the domestic and industrial sector will increase. Countries which do not follow the path of selling raw materials but are engaged in more refined processing and exportation of finished goods will economically benefit from this market based on China’s current experience.

A Modified Model for Flexibility Analysis in Chemical Engineering Processes

This paper discussed an extended model for flexibility analysis of chemical process. Under uncertainty, probability density function is used to describe uncertain parameters instead of hyper-rectangle, and chance-constrained programming is a feasible way to deal with the violation of constraints. Because the feasible region of control variables would change along with uncertain parameters, its smallest acceptable size threshold is presented to ensure the controllability condition. By synthesizing the considerations mentioned above, a modified model can describe the flexibility analysis problem more exactly. Then a hybrid algorithm, which integrates: stochastic simulation and genetic algorithm, is applied to solve this model and maximize the flexibility region. Both numerical and chemical process examples are presented to demonstrate the effectiveness of the method.

Chemical Reactions between CaZrO3 and SiC in Ar Atmosphere

The Chemical reactions between CaZrO3-SiC at high temperature (1200℃－1600℃） in Ar atmosphere have been investigated.The results have indicated that at high temperatures,chemical reactions would occur between CaZrO3 and SiC;the reaction products would change with increas of temperature.In Ar atmosphere CaZrO3 and SiC will react when the temperature reaches 1300℃，At 1300℃－1400℃ ZrC is formed ;above 1400℃ ZrC is transformed to ZrO.     

Chemical Reactions Trigger Peptide Self-Assembly in vivo for Tumor Therapy

Self-assembly peptide materials have promoted the development of science research including life science, optics, medicine, and catalysis over the past two decades. Especially in tumor treatment, peptide self-assembly strategies have exhibited promising potential by their high degree of biocompatibility, construction modularization, and diversity in structure controllability. Driven by physical and chemical triggers, peptides can self-assemble in vivo to form fibers, spheres, hydrogels, or ribbons to achieve predeterminate biological functions. Peptide self-assembly triggered by chemical reactions provides superior specificity and intelligent responsiveness to produce assembly-induced biological effects in target regions. Herein, from the perspective of triggers of peptide assembly, we briefly review the applications of in vivo peptide self-assembly strategies for tumor treatment, including tumor-pathology-factor-induced chemical reactions and bio-orthogonal reactions
