Through-space and hyperconjugative transmission pathways and ring strain are identified as responsible for the opposite trend between 3JHFF and bond angle, and for the negative signs obtained for the two molecules, respectively. One of the fluorine lone pairs, σCα′–HF, σCα–F, σCα′...
What is a temperature scale? What is angle strain in organic chemistry? What are the quadrants of the abdomen? What is normal body temperature in degrees celsius? What is the maximum temperature? What direction does heat flow? Where does a compass point? What is gyroscopic precession? What is...
When an SR gel is stretched, the crosslinks are believed to slide along the polymer chain so as to minimize the local strain. This mechanism guarantees high elasticity and high deformability of SR gels. The type of 2D-SANS patterns depends on the crosslinker concentration, Cx. If Cx is low...
We believe that this work provides a stimulus to further study the still unexplored basic properties of suspended 2D materials, as their surface chemistry, surface energy, compressive and flexural strength, and device interaction at a millimeter-scale level in a free-standing geometry. ...
Examines the effect of C-O-C bond angle strain on the regioselective double nucleophilic substitution of the acetal group of tetraacetal tetraoxa-cages. Novel hydride rearrangement of tetraoxa-cages; Confirmation of the symmetric substitution products; Utilization of an X-ray analysis of the ...
The Al-Li alloy system shows age hardening, resulting from precipitation of metastable δ' (AlLi) particles which have an ordered Listructure (CuAu type). The δ' phase produces a small lattice mismatch with the solution matrix; strain effects are thereby minimized. As a result, Δ' ...

In addition, the cooling phase occurring when the temperature drops from 500 to 25 °C in a short time (a few minutes) induces supplementary strain due to the mismatch of the expansion coefficients between the film and the substrate, leading to the formation of additional cracks on the ...
When this interface is saturated, small nanoparticles grow on top and form nanopillars with ongoing deposition due to minimization of strain. metal-organic Alq3 layer [213]. Alq3 (tris(8-hydroxyquinolinato)aluminum) is a small molecule containing a complexed Al atom commonly used in organic light...
