Crystal structure of 2-(4-chlorophenyl)-3-(4-methoxyphenyl)-3-(methylsulfanyl)acrylonitrile

open access: yesActa Crystallographica Section E, 2014
In the title compound, C17H14ClNOS, the aromatic rings are inclined to one another by 64.22 (9)°. The acrylonitrile group (C=C—C[triple-bond]N) is planar to within 0.003 (2) Å, with the S atom and the methyl C atom displaced from this plane by 0.2317 (6)

Electrochemistry of 2,2'-Bipyridine Complexes of Cobalt in the Presence of Acrylonitrile [PDF]

open access: yes, 1978
The previously claimed (1) catalysis of the electroreduction of acrylonitrile by means of a complex of Co(I) and 2,2′‐bipyridine is shown to be erroneous. The “catalytic currents” result instead from the two‐electron reduction of a mixed complex of Co(I)

Non-Einstein Viscosity Phenomenon of Acrylonitrile–Butadiene–Styrene Composites Containing Lignin–Polycaprolactone Particulates Highly Dispersed by High-Shear Stress

open access: yes, 2019
Lignin powder was modified via ring-opening polymerization of caprolactone to form a lignin–polycaprolactone (LPCL) particulate. The LPCL particulates were mixed with an acrylonitrile–butadiene–styrene (ABS) matrix at an extremely high rotational speed ...

Geometric Optimization and Mechanical Performance Enhancement of Auxetic Structures for High‐Impact Applications Through Fused Deposition Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the mechanical performance of three auxetic structures, identifying a re‐entrant‐star hybrid as the most effective for impact absorption. Finite element simulations and experiments demonstrate significant gains in energy absorption and flexural strength after geometric optimization. This study investigates the mechanical performance

Viscoelasticity‐Induced Controllable Periodic Meso‐Textures of Liquid Crystal Polymers in Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...
