Synthesis, Reactivity, and Electronic Properties of 6,6-Dicyanofulvenes

open access: yes, 2016
A series of 6,6-dicyanofulvene derivatives are synthesized starting from masked, dimeric, or monomeric cyclopentadienones. The reactivities of 6,6-dicyanofulvenes relative to their parent cyclopentadienones are discussed.

The influence of fibre length, diameter and concentration on the strength and strain to failure of glass fibre-reinforced polyamide 6,6 [PDF]

open access: yes, 2008
Results of an investigation of the mechanical performance of injection moulded long glass fibre-reinforced polyamide 6,6 composites are presented. The glass fibre content in these composites was varied over the range 10-50% by weight using fibres with ...

Effect of Frozen Treatment on the Sensory and Functional Quality of Extruded Fresh Noodles Made from Whole Tartary Buckwheat

open access: yes, 2022
Extruded noodles made from whole Tartary buckwheat are widely known as healthy staple foods, while the treatment of fresh noodles after extrusion is crucial. The difference in sensory and functional quality between frozen noodles (FTBN) and hot air-dried

The separation of americium(III) from europium(III) by two new 6,6'-bistriazinyl-2,2'-bipyridines in different diluents [PDF]

open access: yes, 2011
The synthesis and extraction of americium(III) and europium(III) from aqueous nitric acid solutions by the new BTBP ligands 6,6’-bis(5,5,7,7- tetramethyl-5,7-dihydrofuro[3,4-e]-1,2,4-triazin-3-yl)-2,2’-bipyridine (Cy5-O-Me4-BTBP), and 6,6’-bis(5,5,7,7 ...

Covalent Poisons and Catenation: The Effects of Natural Products and DNA Topology on Reactions Catalyzed by Type II Topoisomerases

open access: yes, 2022
Type II topoisomerases are necessary enzymes that regulate the topological state of DNA by creating transient double-stranded breaks. Topoisomerase II poisons act by stabilizing the covalent enzyme-cleaved DNA complex, eventually overwhelming the cell ...

Interfacial strength in thermoplastic composites - at last an industry friendly measurement method? [PDF]

open access: yes, 2002
Many elegant techniques have been developed for the quantification of composite micro-mechanical parameters in recent years. Unfortunately, most of these techniques have found little enthusiastic support in the industrial product development environment,

A study of intermediate Heisenberg spin exchange in DTBN [PDF]

open access: yes, 1982
The E.S.R. spectral line shapes of DTBN in Mesitylene and Cis and Trans-decahydronaphalene were studied. The concentration of DTBN was reduced from the strong to the weak exchange regions using U.V. irradiation.

Guest Inclusion in Cucurbiturils Studied by ESR and DFT: The Case of Nitroxide Radicals and Spin Adducts of DMPO and MNP

open access: yes, 2016
We present an ESR and DFT study of the interaction of cucurbiturils CB[6], CB[7], and CB[8] with di-tert-butyl nitroxide ((CH3)3C)2NO (DTBN) and with spin adducts of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) and 2-methyl-2-nitrosopropane (MNP). The primary

Thermally Activated Delayed Photoluminescence Enables Visible-to-Ultraviolet B Photon Upconversion from ZnSe-PTA to DTBN

open access: yes
A ZnSe quantum-dots-based hybrid system with 9-phenanthrenecarboxylic acid (PTA) transmitter and 2,6-di-tert-butylnaphthalene (DTBN) annihilator is constructed, realizing visible-to-ultraviolet B triplet–triplet annihilation photon upconversion (TTA-UC ...

Promoting effects of desilication and dealumination on the catalytic performance of Al-rich HMOR for catalysing naphthalene tert-butylation with tertiary butanol

open access: yes, 2019
tert-Butylation of naphthalene is a potential technology to produce 2,6-di-tert-butylnaphthalene (2,6-DTBN), which is a valuable raw material for the synthesis of polyethylene naphthalate (PEN).
