A chemical and mechanical evaluation of interfacial fracture in dicyandiamide cured epoxy/steel adhesive systems
The interfacial fracture performance of dicyandiamide cured epoxy/steel adhesive systems was thoroughly investigated. Fracture mechanics based testing was utilized to study several variables which were believed to influence the epoxy/steel interphase region, specifically the elasomeric toughener …

Inhibition of Thiobacillus ferrooxidans using antibiotics and antibacterial substances
… substances [N-serve(nitrapyrin) and Dicyandiamide] effectively inhibited the oxidation of Fe²⁻ ions in the medium. The kinetics of Fe²⁻ oxidation with the addition of antibiotics and the antibacterial substances was studied. N-serve [2-chloro-6-(trichloromethyl) pyridine], used as a …

Nitrogen loss inhibitors in intensively managed winter wheat
… Ammonium polyphosphate, ammonium thiosulfate, dicyandiamide, potassium chloride, and monoammonium phosphate were chosen for use in the present study. They were mixed, singly and in combinations, with UAN solution or urea solution and spring top-dressed on soft red winter wheat. Experiments were …

The Development of Chitosan Microspheres for Use as Agrochemical Delivery or Agropollutant Adsorption Systems
… delivery system for the nitrification inhibitor, dicyandiamide (DCD) and the development of a hydrogel bead adsorption system for the herbicide, paraquat. The hydrogel bead was based on the biopolymer chitosan which was protonated in order for it to be soluble in water. The aqueous chitosan …

Nitrogen and genotype effects on assimilate partitioning and resistance to Striga in maize
… (NH\sb4)SO\sb4$ plus the nitrification inhibitor dicyandiamide (DCD), while a second experiment evaluated similar N rates applied at 14, 21, 28 and 35 days after planting. Regarding genotypes, one experiment evaluated the maize cultivars KCB, H632, H512 and H622, while another examined 16 diverse …

Strategies to improve crop recovery of swine manure nitrogen
… the effectiveness of a nitrification inhibitor dicyandiamide (DCD) added to LSM. Crop recovery of N applied through LSM application was assessed by measuring seed and straw yield and total N content. The effect of adding supplemental P fertilizer at 6.5 kg P ha-1 to swine manure amended soil on …

The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
… for forage kale. The nitrification inhibitor, dicyandiamide (DCD), and a carbon-rich biochar were also used as soil amendments to mitigate N₂O emissions. Total N₂O emissions from trampled soil ranged from 1.3% to 1.9% of urine-N applied to the soil. When applied at 20 kg ha⁻¹, DCD reduced total …

Rapid Startup of Aerobic Granular Sludge Using Cationic Polymer For Industrial Wastewater Treatment
… organic pollutants. For the removal of color, a dicyandiamide formaldehyde (DCF) decoloring agent was used which resulted in over 90% removal. For 44-58 days of operation of the reactor, the removal efficiency of organic pollutants was disrupted due to the decoloring agent. However, after 58 …
