Self-​assembly of thiacyanine dyes in water for the synthesis of active hybrid nanofibres [PDF]

, 2016
Water-​sol. self-​assembled nanostructures were synthesized by simple counter ion exchange of thiacyanine dyes which helps in the formation of nematic (N) and hexagonal (M) chromonic liq.-​cryst. (CLCs) phases. Conjugated double bonds as central spacers

Biodegradation Behavior of Neat PLA Fibers Under Controlled Industrial Composting Conditions: Fiber Characterization and Physical Changes During the Composting Process

Journal of Applied Polymer Science, EarlyView.
Poly(lactic) acid (PLA) biodegradability in fiber form is relatively unexplored. This study shows that the drawing of the fibers during production affects the mechanical properties but slows down the biodegradation of the PLA. Biodegraded undrawn fibers showed peeling whereas drawn fibers showed crack formation on the surface.

Studying the Outcomes and Mechanisms of Carbocationic Rearrangements Using Algorithm‐Augmented Experimentation

ChemistryEurope, EarlyView.
HopCat, a hybrid algorithm combining rule‐based transformations with quantum‐informed kinetics, can be applied to acid‐catalyzed terpenoid rearrangements. In synergy with human chemists and nuclear magnetic resonance analysis, it facilitates product assignment, candidate selection, and reconstruction of complex mechanistic pathways.

Pivotal Synthesis of Tetrasubstituted Epoxides from Ketones and α‐Halo B/Si Ylides with Understanding of the Activation Modes

ChemistryEurope, EarlyView.
The preparation of diastereoselective 1,1,2,2‐tetrasubstituted borosilylepoxides is described, involving the epoxidation of ketones with α‐monohalo borylsilylmethane reagents. The nature of the ambiphilic reagent suppressed the Boron‐Wittig olefination.
