Effects of Chemical Pressure on Superconductivity in Electrochemically Intercalated (TMA)yFe2(Se1−xSx)2 (TMA = Tetramethylammonium)

open access: yesAdvanced Functional Materials, EarlyView.
Intercalation of a series of FeSe1−xSx host crystals with tetramethylammonium cations (TMA+) linearly scales the critical temperature Tc from 43 K down to 28 K with increasing sulfur incorporation. The chemical pressure induced by the partial substitution shows a weakening of the superconducting properties in both hosts and intercalates in a remarkably

Polymer Brush Growth by Surface‐Initiated Ring‐Opening Polymerization from a Cross‐Linked Polymer Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
A stable cross‐linked ultra‐thin polymer coating for surface‐initiated ring‐opening polymerization (SI‐ROP) of hexamethylcyclotrisiloxane and ε‐caprolactone for growth of high grafting density poly(dimethyl siloxane) and poly(caprolactone) brushes is developed.

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

open access: yesAdvanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...
