Molecular adaptations specific to extreme halophilic archaea could promote high perchlorate tolerance

Applied and Environmental Microbiology
Perchlorate is a strong chaotropic agent that causes macromolecule denaturation, DNA damage, and oxidative stress. However, perchlorate deliquescence is thought to promote the formation of liquid salt brines, even at hyper-arid and cold environments ...

Traditional vs. Energetic and Perchlorate vs. “Green”: A Comparative Study of the Choice of Binders and Oxidising Agents

Molecules, 2023
The aim of this article is to compare rocket propellants containing a traditional binder (hydroxyl-terminated polybutadiene) and an energetic binder (glycidyl azide polymer), as well as a perchlorate oxidising agent and a “green” one, i.e., ammonium ...

Studies on Counter Electrode Materials in Aqueous Zinc Half‐Cell Configurations

Advanced Science, EarlyView.
Coulombic efficiency is a key metric for zinc reversibility in aqueous zinc‐ion batteries, but its reliability in zinc half‐cells is strongly influenced by poorly understood counter‐electrode materials. By systematically comparing Cu, Ti, stainless steel, and Al to identify reactions associated with current collectors, we find that Ti is the metal ...

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

Angewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

Study on the affecting factors of perchlorate biodegradation

Journal of Hebei University of Science and Technology, 2015
The environmental pollution of perchlorate is more and more serious because of its widely usage. Several parameters affecting perchlorate degradation are examined through batch experiments by perchlorate-degrading bacteria, which include temperature, pH,

Influence of d-Orbital Occupancy on Ligand Conformation and Crystal Packing in a Series of Mononuclear Transition Metal Complexes. [PDF]

ChemistryOpen
Five new mononuclear complexes of the form [ML]X2 are reported herein. Structural changes and effects on crystal packing arrangements caused by octahedral distortion in the coordination sphere have been studied. A series of mononuclear metal complexes were synthesised incorporating either Mn(II), Co(II), Ni(II), Cu(II), or Zn(II) metal ions in ...

2,6-Diethylanilinium perchlorate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
The asymmetric unit of the title mol-ecular salt, C(10)H(16)N(+)·ClO(4) (-), contains two cations and two anions. The atoms of one of the ethyl side chains of one of the cations are disordered over two sets of sites in a 0.531 (13):0.469 (13) ratio. In the crystal, the components are linked by N-H⋯O and bifurcated N-H⋯(O,O) hydrogen bonds and weaker C ...

A Decoy‐Receptor‐Armed Biomimetic Nanotherapeutic With Inherent Tropism for Conserved Pathogenic Macrophages for Treating Osteoarthritis and Intervertebral Disc Degeneration

Advanced Science, EarlyView.
A biomimetic doppelgänger nanosystem neutralizes extracellular inflammatory cytokines and silences intracellular pyroptosis, reprogramming pathogenic macrophages to attenuate both joint and spine degeneration. ABSTRACT Osteoarthritis (OA) and intervertebral disc degeneration (IVDD) are debilitating musculoskeletal disorders driven by shared ...
