Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Data Driven Control of Defect Formation in Solution Deposited Sb2Se3 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
A data‐driven design of experiments (DoE) approach is used to uncover how six interdependent processing parameters govern defect formation in solution‐deposited Sb2Se3 thin films. Statistical modeling revealed strong non‐linear couplings that control film quality, and the optimized films showed a threefold enhancement in photoresponse, demonstrating ...

One‐Step Copper‐Assisted Synthesis of α‐(Styrylsulfonyl)amides via SO2 Incorporation Under Visible Light

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
α‐(Styrylsulfonyl)amides are prepared from α‐bromoamides, SO2, and styrenes in a one‐step photoredox‐catalyzed reaction in the presence of a copper complex. Additionally, related ester analogs could be synthesized following the same procedure. The mechanism of the newly developed method is investigated and model postmodification reactions are carried ...
