Volatile Relay Biosensing and Mobile Phone Imaging for Detection of Influenza Virus

open access: yesAdvanced Functional Materials, EarlyView.
Detection of volatile organic compounds is performed via a coupled enzymatic assay with mobile phone detection of the signal. Specific application demonstrated herein is the detection of influenza virus, across multiple levels of biological complexity, up to patient‐derived samples.

Spectral Characteristics of Dissolved Organic Matter and Their Associations with Heavy Metal Distribution in Multi-Media of a Typical Frozen Eutrophic Lake

open access: yesToxics
In cold arid regions, the relationships between dissolved organic matter (DOM) characteristics and heavy metal distributions across ice, water, and sediment interfaces remain insufficiently resolved.

Bridging Polymer Brushes and Coatings Through Ultra‐Thick Growth by Surface‐Initiated Photoiniferter Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Surface‐initiated photoiniferter‐mediated polymerization (SI‐PIMP) enables the controlled growth of UHMW polymer brushes with multi‐micrometer thicknesses, bridging conventional brushes and bulk‐like coatings. UHMW brushes are synthesized through a controlled/living process; they provide low friction and enhanced wear resistance under aqueous ...

A Study of the In-Vial Crystallization of Ice in Sucrose–Salt Solutions—An Application for Through-Vial Impedance Spectroscopy (TVIS)

open access: yesApplied Sciences
Ice nucleation temperatures and associated ice growth rates are critical parameters in defining the initial ice morphology template, which governs dry layer resistance during sublimation and therefore impacts primary drying kinetics and overall process ...

Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Identification of Imitation Cheese and Imitation Ice Cream Based on Vegetable Fat Using NMR Spectroscopy and Chemometrics

open access: yesInternational Journal of Food Science, 2013
Vegetable oils and fats may be used as cheap substitutes for milk fat to manufacture imitation cheese or imitation ice cream. In this study, 400 MHz nuclear magnetic resonance (NMR) spectroscopy of the fat fraction of the products was used in the context

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

open access: yesAdvanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Effect of Regolith–Ice Stratigraphy and Laser Weathering on Ultraviolet–Visible–Near-infrared Detection of Lunar Water Ice

open access: yesThe Planetary Science Journal
Investigating volatiles is critical for understanding their delivery to the Moon and for their potential as a resource for sustained lunar exploration. Water ice and potentially other volatiles are known to exist in and proximal to permanently shadowed ...

Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...
