Leaching of melamine and cyanuric acid from melamine-based tableware at different temperatures and water-based simulants

Environmental Chemistry and Ecotoxicology, 2020
Following food scandals involving melamine during 2007–2008, health risks from human exposure to this compound received worldwide attention. Since then several studies have reported sources of melamine exposure in humans. In this pilot study, leaching of

Synthesis, Characterization and Antimicrobial Activity of Copper-Metal Organic Framework (Cu-MOF) and Its Modification by Melamine

Journal of Inorganic and Organometallic Polymers and Materials, 2021
Copper-Metal organic framework (Cu-MOF) and melamine/Cu-MOF (MCu-MOF) samples were prepared by the hydrothermal process. The produced powder was dried and characterized by using the FTIR, X-ray techniques.

Release of Melamine and Formaldehyde from Melamine-Formaldehyde Plastic Kitchenware

Molecules, 2020
The release of melamine and formaldehyde from kitchenware made of melamine resins is still a matter of great concern. To investigate the migration and release behavior of the monomers from melamine-based food contact materials into food simulants and ...

Resolving a Nearly Two-Centuries-Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide. [PDF]

Chemistry
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

Longterm Influence of Inertia on the Diffusion of a Brownian Particle [PDF]

, 2014
We demonstrate experimentally that a Brownian particle is subject to inertial effects at long time scales. By using a blinking optical tweezers, we extend the range of previous experiments by several orders of magnitude up to a few seconds.

Associations of melamine and cyanuric acid exposure with markers of kidney function in adults: Results from NHANES 2003–2004

Environment International, 2020
Higher melamine exposure may increase the risk of kidney stone formation and kidney injury in infants, but little is known about the potential nephrotoxic effects of environmental low-dose melamine and its derivative exposure on kidney function of adults

Supramolecular Assemblies of Melamine-2-Thiobarbiturate and Melamine-Barbiturate-2-Thiobarbiturate: Experimental and Theoretical Studies

Crystals, 2023
In this work, we considered the formation of supramolecular assemblies of melamine-thiobarbiturate and melamine-barbiturate-thiobarbiturate. It is known that thiobarbituric acid can form many tautomers, as well as different motifs due to the change of C2=
