Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Spatial structure of m- and o-substituted isologous aryl cyanates [PDF]

, 1981
1. m-Substituted isologous phenyl cyanates exist in solution as mixtures of the syn- and anti-forms. The fraction of the latter, as well as the dihedral angles between the planes of the aromatic ring and CarECN, increase with the increasing acceptor ...

Long Fluorescence Lifetime Molecular Rotors Based on the 4,4‐Dicyano‐BODIPY Core

Chemistry – A European Journal, EarlyView.
Substituting fluorine with cyano groups in BODIPY‐based fluorescent molecular rotors yields viscosity‐sensitive dyes with significantly enhanced fluorescence lifetimes that can be used for viscosity mapping in living cells using FLIM microscopy. ABSTRACT Environmentally sensitive fluorescent probes with extended emission lifetimes are highly valuable ...

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

TRIMERIZATION OF ARYL CYANATES THERMALLY CURABLE OLIGOMERS

, 1984
Aryl cyanates have been used as reactive terminal groups for crosslinking oligomers. With heat, aryl cyanates trimerize to thermally stable aryloxy - s-triazine rings via an additional reaction.

Cyanate as an energy source for nitrifiers [PDF]

Nature, 2015
Ammonia- and nitrite-oxidizing microorganisms are collectively responsible for the aerobic oxidation of ammonia via nitrite to nitrate and have essential roles in the global biogeochemical nitrogen cycle. The physiology of nitrifiers has been intensively studied, and urea and ammonia are the only recognized energy sources that promote the aerobic ...

Mechanistic Understanding of Nickel Catalyzed Urea Oxidation Reaction to Cyanate and Nitrite

Exploration, EarlyView.
The urea oxidation reaction (UOR) is a promising alternative to oxygen evolution reaction (OER) for energy efficient hydrogen production, yet its reaction mechanism remains controversial because many proposed pathways have not been directly correlated with experimentally verified products and intermediates.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.
