The result shows that the BB bond is a good electron donor in halogen bonding, particularly for the halogen donor XF. Interestingly, for the halogen donor XF, the halogen bond becomes stronger in order of IF 2-BrCN is combined with another interaction, its strength has a further increase ...
Among the four cocrystals, the halogen bonding interactions play an important role in assembling properties and the large red spots on Hirshfeld surface imply the strong strength. Notably, the IFB㏄hZ cocrystals exhibit a phosphorescence emission at peak of 733 nm with a lifetime up to 159 s. ...
Good linear correlations between cooperativity parameters and electronic properties of complexes were established in the present study. 展开 关键词: Cooperativity Halogen bonding Lithium bonding Tetrel bonding DOI: 10.1007/s00894-015-2722-1 被引量: 8 ...
Flame retardancy although it is halogen-free, with good bonding strength, soldering heat resistance and coefficient of thermal expansion; novolak epoxy resin, carboxylic acid-modified acrylonitrile butadiene rubber particles, a triazine ring-containing cresol novolak, phenolic phosphorus compound, filler...
When evaluating the mean shear bond strengths of the 4 groups tested 30 minutes after bonding, no statistically significant differences were found between the control group cured with the halogen light for 20 seconds and brackets bonded with the plasma arc light with curing times of 2, 6, or ...
Micro-tensile bond strengths of beams were measured (EZ-Test 0.5mm/min). For biaxial testing, resin discs (0.6-mm thick, 6.2-mm diameter) were prepared in Teflon molds (n=10). Adhesives were applied incrementally to the molds and light-activated: halogen light-curing unit, Optilux 501. ...
Objective : The present study aimed at assessing the efficacy of moisture insensitive primer in moist environment and the effect of precoating the bracket base with the adhesive and modifying adhesive composition on the shear bond of the material. The study compared the shear bond strength of Trans...
A solvent vapour thermoplastic bonding process is reported which provides high-strength bonding of PMMA over a large area for multi-channel and multi-layer
For instruments employing two lamps, a tungsten or halogen lamp is commonly used for visible light,2 whilst a deuterium lamp is the common source of UV light.2 As two different light sources are needed to scan both the UV and visible wavelengths, the light source in...
The compactModel 3442extensometer measures strain in this tensile test through failure of AISI 1080 high strength steel. The music wire rod in this test has a 4.7 mm diameter. The extensometer may be used for determining elastic modulus, offset yield strength, ultimate elongation, and stress-strai...
