One of the key concerns of the people and the government of China is food safety. After the use of melamine as an additive was reported in 2008, melamine detection was required in milk. The current methods to detect and confirm melamine are mainly HPLC and HPLC-MS/MS, but the pre-treatment processes include some tedious steps making them time-consuming and environmentally unfriendly. In contras...

Melamine formaldehyde microcapsules containing paraffin wax as phase change material (PCM) were synthesized. Free space was generated in-situ inside microcapsules. These characterized by FTIR Spectrophotometer, Scanning electron microscope (SEM), Differential colorimeter (DSC), and optical microscope. It confirmed that PCM successfully encapsulated the shell material. Encapsulated showed good p...

A foam-like mesoporous polymer of melamine-formaldehyde (mPMF) was synthesized and further deposited on disposable screen-printed electrodes (SPEs) for the electroanalysis of Pb(2+) ions in blood. Investigations indicate that the prepared mPMF is ultrastable in water, showing a mesoporous structure and an amine-rich composition, as characterized by electronic microscopy images and IR spectra. I...

Determining adhesive bond performance for chemically modified wood is important not only its commercial utility but also understanding durability. Bulking modifications occupy space inside the cell wall, limiting available water. We used two bulking on yellow poplar (Liriodendron tulipifera L.): acetylation (Ac), which bulks and converts a hydroxyl group to an ester, while butylene oxide (BO) p...

Recent cases of adulteration with melamine have led to the need for rapid and reliable screening methods. To meet this need, commercial enzyme-linked immunosorbent assay (ELISA) test kits for the detection of triazines were evaluated. The recently released Melamine Plate kit (Abraxis, Warminster, Pa.) displayed a limit of detection of 9 ng/ml for melamine in phosphate-buffered saline (PBS) and ...

Melamine is a nitrogen heterocyclic triazine compound which is widely used as an industrial chemical. Although melamine is not considered to be acutely toxic with a high LD50 in animals, food contaminated with melamine expose risks to the human health. Melamine has been reported to be responsible for the renal impairment in mammals, its toxicity on the reproductive system, however, has not been...

High-pressure laminates (HPLs) are durable, resistant to environmental effects and good cost-benefit decorative surface composite materials with special properties tailored to meet market demand. In the present work, polyhexamethylene biguanide (PHMB) was incorporated for the first time into melamine-formaldehyde resin (MF) matrix on the outer layer of HPLs to provide them antimicrobial propert...

Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from gold-coated mono-disperse spherical melamine-formaldehyde monomers in a radiofrequency (rf) argon discharge plasma. The behavior of observed dust aggregates is analyzed both ...
