Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells

Advanced Materials, EarlyView.
A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Perceived safety in community and service settings among young adults experiencing homelessness: Differences by sexual and gender identity

American Journal of Community Psychology, Volume 70, Issue 3-4, Page 340-351, December 2022., 2022
Abstract Homelessness poses risks to the health and safety of young adults; particularly among sexual and gender minority (SGM) young adults. The current study sought to better understand service use and perceived safety in community and service settings among SGM and cisgender heterosexual (cis‐hetero) young adults experiencing homelessness. Data come

Leveraging Multifaceted Polyphenol Interactions: An Approach for Hair Loss Mitigation

Advanced Materials Interfaces, EarlyView.
This study presents tannic acid as an effective alternative to traditional hair loss treatments. Acting as an adhesion mediator, tannic acid binds to keratin on the hair surface and sequesters SCANDAL—a blend of salicylic acid, niacinamide, and dexpanthenol—allowing gradual release to hair follicles.

Atomic Layer Deposition of ZnO Coating on Biodegradable Fe‐Based Alloys

Advanced Materials Interfaces, EarlyView.
A biodegradable Fe69Mn30C1 alloy is coated with ZnO using atomic layer deposition at 100 °C. Coating thickness impacts surface roughness, wettability, and in vitro degradation while maintaining hydrophilicity. The ZnO coating exhibits significant antibacterial activity against Staphylococcus aureus, achieving an inhibitory rate of up to 99.2%, and can ...

Investigation On The Role of Cavity and Slit of Cavity Resonators to Sound Absorption Behavior [PDF]

, 2011
Slit resonator and also perforated resonator are few kind of room interior finishing. They act as sound absorbers. Gen-erally, they are constructed of at least three basic types of absorbers, such as porous, membrane and cavity compo-nents.These types of

Time‐ and Frequency‐Domain THz Imaging for the Characterization of Subwavelength Tags in Anticounterfeiting Devices

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 ...
