Biological reduction of perchlorate in ion exchange regenerant solutions containing high salinity and ammonium levels

, 2002
The most promising technologies to remove perchlorate from water are ion exchange and biological reduction. Although successful, ion exchange only separates perchlorate from water; it does not eliminate it from the environment.

Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

Advanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and

Structure and evolution of chlorate reduction composite transposons. [PDF]

, 2013
UnlabelledThe genes for chlorate reduction in six bacterial strains were analyzed in order to gain insight into the metabolism. A newly isolated chlorate-reducing bacterium (Shewanella algae ACDC) and three previously isolated strains (Ideonella ...

Copper(II), a Peculiar Metal Ion for Complexation with Monensin A Ionophore

Chemistry – A European Journal, EarlyView.
Copper(II) forms three chiral and EPR‐active complexes with monensinate A in methanol. Beside the bis [CuL2] and mono [CuL]+ species, the new dinuclear construct [Cu2L]3+ exhibits an [ML]+‐type and a metal salt‐type copper(II) centers weakly bound to each other through counter ion(s) and thus, being magnetically independent.

Thermal decomposition study of perchlorate-based metal-free molecular perovskite DAP-4 mixed with ammonium perchlorate

Case Studies in Thermal Engineering, 2022
The molecular perovskite energetic materials (H2dabco)[NH4(ClO4)3] (DAP-4, H2dabco2+ = 1,4-diazabicyclo[2.2.2]octane-1,4-diium), limits its separate application in explosives duo to the severe negative oxygen balance.

Resolving a Nearly Two‐Centuries‐Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide

Chemistry – A European Journal, EarlyView.
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.
