Response of Inconel 617 superalloy to combined ground-based and STS reentry exposure [PDF]

open access: yes
Inconel 617 is a nickel-based superalloy which is being considered for heat-shield applications because of its high-temperature strength, good oxidation resistance and high emittance of oxidized surfaces. While the effects of simulated reentry conditions

Patterned Assembly of Transition Metal Dichalcogenide/Graphene Heterostructures via Direct Laser Writing

open access: yesAdvanced Functional Materials, EarlyView.
The fabrication of patterned transition metal dichalcogenide (TMD)/graphene heterostructures via direct laser writing reveals new interface chemistry and enables efficient, customizable assembly. Selective laser irradiation of functionalized TMD/graphene triggers localized reactions, forming chemically modified interfaces.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

open access: yesAdvanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Turbine Airfoil Deposition Models [PDF]

open access: yes
Gas turbine failures associated with sea-salt ingestion and sulfur-containing fuel impurities have directed attention to alkali sulfate deposition and the associated hot corrosion of gas turbine (GT) blades under some GT operating conditions.
