Spin-crossover behaviors in solvated cobalt(II) compounds [PDF]

open access: yes, 2015
Two solvated cobalt(ii) terpyridine complexes, [Co(MeO-terpy)2](BF4)2·H2O (1·H2O) and [Co(MeO-terpy)2](BF4)2·acetone (1·acetone) were prepared. Annealing each of these complexes resulted in the formation of two desolvated species, 1 and 1′, respectively.

Maya Blue‐Inspired Hybrid Coating for Robust and Superhydrophilic Solar Evaporators Using Commercial Black Acrylic Paint

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates a Maya blue‐inspired hybrid solar evaporator using commercial black acrylic paint, achieving 98% solar‐thermal conversion efficiency and 2.39 kg m−2 h−1 water evaporation rate through a durable, hydrophilic organic–inorganic structure that enables scalable, cost‐effective desalination and wastewater purification.

Synthesis, Characterization and Crystal Structures of Cobalt(II), Zinc(II) and Cadmium(II) Complexes Derived from 2-Hydroxy-N’-(pyridin-2-ylmethylene)benzohydrazide with Antimicrobial Activity

open access: yesActa Chimica Slovenica, 2019
Three new cobalt(II), zinc(II) and cadmium(II) complexes, [CoL2]·2CH3OH·H2O (1), [ZnL2] (2) and [Cd(HL)2(NO3)]N3 (3), were prepared from 2-hydroxy-N’-(pyridin-2-ylmethylene)benzohydrazide (HL).

Electrochemistry of 2,2'-Bipyridine Complexes of Cobalt in the Presence of Acrylonitrile [PDF]

open access: yes, 1978
The previously claimed (1) catalysis of the electroreduction of acrylonitrile by means of a complex of Co(I) and 2,2′‐bipyridine is shown to be erroneous. The “catalytic currents” result instead from the two‐electron reduction of a mixed complex of Co(I)

Reactions of HNO with Metal Porphyrins: Underscoring the Biological Relevance of HNO [PDF]

open access: yes, 2014
Azanone (1 HNO, nitroxyl) shows interesting yet poorly understood chemical and biological effects. HNO has some overlapping properties with nitric oxide (NO), sharing its biological reactivity toward heme proteins, thiols, and oxygen.

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

Speciation and stability of methylene blue-metal-thiocyanate ion-association complexes

open access: yesBulletin of the Chemical Society of Ethiopia, 2008
With thiocyanate, zinc(II), cobalt(II) and copper(II) ions form stable anion, [M(SCN) 4]2-. This anion in turn with methylene blue (MB+) forms ion-pair of the type MB2[M(SCN)4] and turns methylene blue to violet. The stoichiometry and stability constants

Oxygen Activation by Mononuclear Mn, Co, and Ni Centers in Biology and Synthetic Complexes [PDF]

open access: yes, 2017
The active sites of metalloenzymes that catalyze O2-dependent reactions generally contain iron or copper ions. However, several enzymes are capable of activating O2 at manganese or nickel centers instead, and a handful of dioxygenases exhibit activity ...

Solvent‐Free Bonding Mechanisms and Microstructure Engineering in Dry Electrode Technology for Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dry electrode technology revolutionizes battery manufacturing by eliminating toxic solvents and energy‐intensive drying. This work details two promising techniques: dry spray deposition and polymer fibrillation. How their unique solvent‐free bonding mechanisms create uniform microstructures for thicker, denser electrodes, boosting energy density and ...

Synthetic metallomolecules as agents for the control of DNA structure [PDF]

open access: yes, 2007
This tutorial review summarises B-DNA structure and metallomolecule binding modes and illustrates some DNA structures induced by molecules containing metallic cations. The effects of aquated metal ions, cobalt amines, ruthenium octahedral metal complexes,
