General description
Surface grafting of cis,cis-1,5-cyclooctadiene (cyclic olefin) with low strain energy was explored using ring-opening metathesis polymerization in the vapor phase. The inclusion complex of cis,cis-1,5-cyclooctadiene with β-cyclodextrin (β-CD) was studied by using proton NMR spectroscopy.
Application
cis,cis-1,5-Cyclooctadiene (COD) has been employed as ligand:
- during regio- and stereoselective synthesis of (Z)-1,2-dihaloalkenes
- in the preparation of metal complexes, e.g. bis-COD-nickel, a versatile reagent for preparing (PI)-allylnickel halides

Valid and comparable cause of death (COD) statistics are crucial for health policy analyses. Variations in COD assignment across geographical areas are well-documented while socio-institutional factors may affect the process of COD and underlying cause of death (UCD) determination. This

Consecutive dark-fermentation and photo-fermentation stages were investigated for a profitable circular bio-economy. H2 photo-production versus poly(3-hydroxybutyrate) (P3HB) accumulation is a modern biotechnological approach to use agro-food industrial byproducts as no-cost rich-nutrient medium in eco-sustainable biological processes. Whey and molasses are

The effects of plant-based carbon source addition on wastewater NO3--N removal and the involved microorganisms, especially denitrifying bacteria, were investigated. A synthetic wastewater (NO3--N, 15 mg/L) was treated through the batch experiment, which included three inoculation cycles (7 days/cycle), and
