Programmable Liquid Crystal Elastomers Via Magnetic Field Assisted Oligomerization

Advanced Functional Materials, EarlyView.
This article presents a straightforward method for designing programmable liquid crystal elastomer (LCE) actuators using magnetic field alignment. It combines thio‐Michael polyaddition for efficient LCE synthesis with a strategy that preserves the nematic phase, enabling the alignment of high molecular weight LCOs.

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Solution-based alkyne-azide coupling on functionalized Si(001) prepared under UHV conditions [PDF]

arXiv, 2020
Synthesis of organic bi-layers on silicon was realized by a combination of surface functionalization under ultra-high vacuum (UHV) conditions and solution-based click chemistry. The silicon (001) surface was prepared with a high degree of perfection in UHV and functionalized via chemoselective adsorption of ethinyl cyclopropyl cyclooctyne from the gas ...
