Advanced Materials Interfaces, EarlyView.2D Ruddlesden‐Popper phase perovskite (RPP) films for applications in photovoltaics are shown to exhibit structural heterogeneities at both microscopic and mesoscopic scales that can affect cross‐film charge carrier transport. The mechanisms of RPP film formation and the possible means to control film structure to optimize 2D perovskite solar cell ...

Development of phosphorylated adhesives [PDF]
The synthesis of epoxy prepolymers containing phosphorus was carried out in such a manner as to provide adhesives containing at least 5 percent of this element. The purpose of this was to impart fire retardant properties to the adhesive.

Self‐Supporting Graphene Foam for the Removal of Chlorine from Water
Advanced Materials Interfaces, EarlyView.Graphene‐based porous materials are promising for sorption and catalysis but often require binders. This study presents a self‐supporting graphene foam made from graphene oxide and hydrazine vapor. Structural, mechanical, and functional analyses confirm its superior chlorine removal efficiency (97%) and reusability, outperforming activated carbon in ...

Advanced Materials Technologies, EarlyView.Non‐faradaic label‐free impedimetric determination of cortisol is demonstrated with gold nanoparticles (AuNP) functionalized laser‐induced graphene interdigitated electrodes (LIG‐IDE). The AuNP functionalized LIG‐IDE exhibits remarkable characteristics including good logarithmic linear range, high reproducibility, repeatability, and robust selectivity.

Streamlined Inkjet‐Printing of Stretchable Organic Photodetectors
Advanced Materials Technologies, EarlyView.This work introduces stretchable photodetectors fully inkjet‐printed on stretchable substrates. It is demonstrated that printed stiff platforms effectively decouple strain from the stretched substrate and serve as a chemically resistant and mechanically rigid platform.

Fire and heat resistant laminating resins based on maleimido and citraconimido substituted 1-(diorgano oxyphosphonyl) methyl -2,4- and -2,6- diaminobenzenes [PDF]
, 1987 A class of fire and heat resistant bisimide resins prepared by thermal polymerization of maleimido or citraconimido substituted 1-((dialkoxyphosphonyl) methyl)-2-4 and -2,6-diaminobenzenes are described. The polymer precursors are prepared by reacting 1-(

Advanced Materials Technologies, EarlyView.This work presents a method to print multi‐layer elastomer structures containing liquid cavities, where the fluid is incorporated as part of the printing process by freezing it, thus avoiding the conventional final filling step. We demonstrate this process by fabricating and characterizing dense arrays of zipping electrostatic actuators.

Advanced Materials Technologies, EarlyView.Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...
