Abstract:

Ethylene is an endogenously synthesized plant hormone that dissipates quickly in field conditions and seldom exceeds five nmol mol-1. Ethylene can accumulate to 1000 times this level in closed environments. The best-known effects of ethylene are its impacts on fruit ripening and senescence, yet ethylene influences growth and development throughout the plant life cycle. At low, continuous concentrations (20 to 50 nmol mol-1), ethylene reduces yield of many plants. Clean-air treatment during critical stages of floral development, silver thiosulfate (STS), and 1-methylcyclopropene (1- MCP) may de

Abstract:

Tetrachloroethylene and its daughter-products represent a group of contaminations which are frequently found at sites with industrial activities, such as metal processing, electrotechnical and pharmaceutical industries as well as dry cleaning of clothing and the production of colours, paints and laquers. Due to their toxicity and persistence under natural conditions "denser-than-water" non aqueous phase liquids are substantial threats to the subsurface environment as well as the surface ecosystems including human beings.

The increasing use of polymeric materials in food packaging applications is due to many factors; however, most are related to cost.

The current work examines the fundamental oxygen and carbon dioxide permeation and sorption properties of amorphous, caffeine antiplasticized PET and amorphous poly(ethylene furanoate) (PEF), which is a new biologically

Recently, a shortage of 1-octene has been observed in the global market.

Abstract:

Polyethylene terephthalate (PET) and polyolefins, such as high density polyethylene (HDPE), are important commodity polymers. PET is widely used for fibres and fllms but is also an attractive material for moulded products, owing to its high melting point and solvent resistance. Crystalline PET, however, is brittle and susceptible to hydrolytic degradation through water absorption. Polyolefins, on the other hand, are tough materials with low water absorption but have a relatively low melting point. Blending these two materials is expected to produce an attractive combination of properties. Blen

However, the marketability of the fruit of A. chinensis and many other species of Actinidia is limited by poor fruit storage properties. Pioneering work in tomato has demonstrated that fruit ripening and senescence can be very effectively delayed by down-regulating genes required for biosynthesis of the phytohormone ethylene.
