Micro Model of Carbon Fiber/Cyanate Ester Composites and Analysis of Machining Damage Mechanism

open access: yesChinese Journal of Mechanical Engineering, 2019
Machining damage occurs on the surface of carbon fiber reinforced polymer (CFRP) composites during processing. In the current simulation model of CFRP, the initial defects on the carbon fiber and the periodic random distribution of the reinforcement ...

Sequence Control in Sulfur‐Containing Ring‐Opening Co‐ and Terpolymerisations

open access: yesAngewandte Chemie International Edition, Accepted Article.
Sulfur‐containing polymers uniquely expand the catalogue of accessible material properties compared to current commodity materials, yet their synthesis remains underdeveloped. Combining sulfur‐ and oxygen‐containing monomers in ring‐opening copolymerisation leads to a reshuffling reaction of the sulfur centres, which has been challenging to control — a

Diverging Reactivity in Anilidophosphine Supported Group III Complexes

open access: yesChemistry – An Asian Journal, EarlyView.
The coordination chemistry and reactivity of anilidophosphine‐supported scandium and yttrium complexes is reported and compared to their lanthanum analogues previously reported by us. The manuscript shows striking differences in the stability and affinity of the anilidophosphine ligand toward these lighter group III metals, resulting in divergent ...

Fabrication and Characterization of a Modified Conjugated Molecule-Based Moderate-Temperature Curing Epoxy Resin System

open access: yesFrontiers in Materials, 2020
A 2-Methylimidazole derivative [ethyl glycidyl ether (EGE)–2-MI] was synthesized through the reaction of EGE with the conjugated molecule 2-MI. The structure was confirmed by Fourier transform infrared spectroscopy, 1H-nuclear magnetic resonance ...

Nanochemistry of fullerene c60. cyano- and azo-polyderivatives [PDF]

open access: yesarXiv, 2010
Cyanation C60 to C60(CN)18 and aziridination from C60 to C60(NH)9 have been studied by unrestricted broken spin symmetry Hartree-Fock approach implemented in semiempirical codes based on AM1 technique. The calculations were focused on successive addition of CN and NH moieties to the fullerene cage following the indication of the cage target atoms by ...

The effect of lipoic acid on cyanate toxicity in different structures of the rat brain [PDF]

open access: yes, 2013
Cyanate is formed mostly during nonenzymatic urea biodegradation. Its active form isocyanate reacts with protein –NH(2) and –SH groups, which changes their structure and function. The present studies aimed to investigate the effect of cyanate on activity

Effect of Cyanate on Erythrocyte Deformability [PDF]

open access: yesBlood, 1974
Abstract Cyanate is undergoing study as a drug to prevent occlusive sickle cell crises. Carbamylation of hemoglobin S increases its oxygen affinity, thereby decreasing its tendency to aggregate at low oxygen tensions. The cell membrane has also been shown to be carbamylated.
