Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

Advanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Cyanide-Limited Complexation of Molybdenum(III): Synthesis of Octahedral [Mo(CN)₆]^3- and Cyano-Bridged [Mo₂(CN)₁₁]^5-

, 2016
Octahedral coordination of molybdenum(III) is achieved by limiting the amount of cyanide available upon complex formation. Reaction of Mo(CF3SO3)3 with LiCN in DMF affords Li3[Mo(CN)6]·6DMF (1), featuring the previously unknown octahedral complex [Mo(CN ...

Designing Strong, Tough, Fire‐Retardant and Self‐Healing Elastomers with Phosphorus/Nitrogen‐ and Biphenyl‐Containing Segments

Advanced Materials, EarlyView.
By designing a P/N‐ and π–π interacting biphenyl‐containing diol as hard segments but side groups, a strong, tough, fire‐extinguishing and self‐healing elastomer is developed, demonstrating a break strain of ∼2500%, a toughness of 379 MJ/m3 and a tensile strength of 46 MPa, as well as a healing efficiency of 95% (tensile strength) and 99% (break strain)

Role of the Dihydrodipicolinate Synthase DapA1 on Iron Homeostasis During Cyanide Assimilation by the Alkaliphilic Bacterium Pseudomonas pseudoalcaligenes CECT5344

Frontiers in Microbiology, 2020
Cyanide is a toxic compound widely used in mining and jewelry industries, as well as in the synthesis of many different chemicals. Cyanide toxicity derives from its high affinity for metals, which causes inhibition of relevant metalloenzymes.

Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

Advanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

Copper and Cyanide Recovery in Cyanidation Effluents

Advances in Chemical Engineering and Science, 2011
Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection

Advanced Materials Interfaces, EarlyView.
A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...
