Comparison of the Effects of Phenylhydrazine Hydrochloride and Dicyandiamide on Ammonia-Oxidizing Bacteria and Archaea in Andosols

open access: yesFrontiers in Microbiology, 2017
Dicyandiamide, a routinely used commercial nitrification inhibitor (NI), inhibits ammonia oxidation catalyzed by ammonia monooxygenase (AMO). Phenylhydrazine hydrochloride has shown considerable potential for the development of next-generation NIs ...

A flame retardant containing dicyandiamide and aluminum hypophosphite for polyethylene

open access: yesCase Studies in Construction Materials, 2023
Polyethylene (PE) is a widely used industrial plastic, but its flammable feature limits its further application. A novel composite based on dicyandiamide (DICY) and aluminum hypophosphite (AHP) was integrated into PE.

Electrochemically modified poly(dicyandiamide) electrodes for detecting hydrazine in neutral pH [PDF]

open access: yes, 2023
A new technique for sensing nanomolar concentrations of hydrazine in water samples is reported. A screen-printed carbon electrode (SPCE) altered using an amine-azo functional group encompassing poly(dicyandiamide) is used in this study.

Adhesion and Hydrothermal Performance of Epoxy-Dicyandiamide Adhesive Film for PMMA-PETR. [PDF]

open access: yesPolymers (Basel)
Epoxy/dicyandiamide adhesive film is required for the bonding of polymethyl methacrylate (PMMA) aircraft cockpit edges. An imidazole/alkanolamine composite accelerator was developed to satisfy the requirement of maintaining a bonding temperature below 90

Maximizing Active Site Density in Tin Single-Site Catalysts for Selective Carbon Dioxide to Formate Electroreduction. [PDF]

open access: yesAngew Chem Int Ed Engl
High‐loading tin single‐site catalysts (>7.5 wt.% Sn) are synthesized using a nitrogen‐enriched carbon scaffold and mechanochemically assisted pyrolysis to stabilize atomically dispersed Sn. The resulting Sn/N‐C‐M catalyst enables highly selective CO2‐to‐formate conversion (>90% FE across 50–500 mA cm−2) with long‐term durability and operando‐verified ...

Multiple small monthly doses of dicyandiamide (DCD) did not reduce denitrification in Waikato dairy pasture [PDF]

open access: yes, 2013
The effectiveness of multiple small doses of the nitrification inhibitor dicyandiamide (DCD) to decrease denitrification under warm moist conditions was tested in a 1-year field trial on a grazed dairy pasture. DCD was applied approximately every 4 weeks

Zinc Oxide and Graphitic Carbon Nitride/ZnO Nanocomposites in Food Safety and Preservation: Synthesis, Antimicrobial Mechanisms, and Application Prospects. [PDF]

open access: yesFood Sci Nutr
ZnO and g‐C3N4/ZnO S‐scheme heterojunctions are synthesized via conventional, green, and biogenic routes. They combat foodborne pathogens and degrade mycotoxins through ROS generation, Zn2+ release, and membrane disruption, enabling antimicrobial packaging, photocatalytic decontamination, and nanobiosensing. However, migration, toxicity, and regulatory

Studies on Melamine. IV : The Reaction Mechanism of the Formation of Melamine from Dicyandiamide [PDF]

open access: yes, 2010
application/pdf(1) In the case of preparing melamine from dicyandiamide in presence of liquid ammonia under pressure, the formation of guanidine as an intermeiate product was proved by isolating it as its picrate. (2) In the above case, dicyandiamide was
