Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

open access: yesAdvanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

open access: yesAdvanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

A chemical probe technique for the determination of reactive halogen species in aqueous solution: Part 1 – bromide solutions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2006
Reactive halogen species (X*=X•, •X2-, X2 and HOX, where X=Br, Cl, or I) in seawater, sea-salt particles, and snowpacks play important roles in the chemistry of the marine boundary layer.

Characterization of Halogen (Cl, Br, I) Emissions from Cooking Fuels in Nigerian Households Using Energy-Dispersive X-ray Fluorescence Spectrometry

open access: yesEQA, 2021
Studies have shown that most of the fuels used in developing countries were generally from wood biomass. Residential emission from traditional biomass cookstoves is a major source of indoor and outdoor air pollution.

Halogen Inhalation-Induced Lung Injury and Acute Respiratory Distress Syndrome

open access: yesChinese Medical Journal, 2018
Objective: Exposure to halogens, such as chlorine or bromine, results in environmental and occupational hazard to the lung and other organs. Chlorine is highly toxic by inhalation, leading to dyspnea, hypoxemia, airway obstruction, pneumonitis, pulmonary
