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

Advanced 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.

Measuring aerosol size distributions with the aerodynamic aerosol classifier [PDF]

Aerosol Science and Technology, 2018
The Aerodynamic Aerosol Classifier (AAC) is a novel instrument that selects aerosol particles based on their relaxation time or aerodynamic diameter. Additional theory and characterization is required to allow the AAC to accurately measure an aerosol's aerodynamic size distribution by stepping whilst connected to a particle counter (such as a ...

Pyrogenic iron: The missing link to high iron solubility in aerosols

Science Advances, 2019
Air pollution creates high Fe solubility in pyrogenic aerosols, raising the flux of biologically essential Fe to the oceans. Atmospheric deposition is a source of potentially bioavailable iron (Fe) and thus can partially control biological productivity ...

Aerosol Jet Printed MXene Microsupercapacitors for Flexible and Washable Textile Energy Storage

Advanced Functional Materials, EarlyView.
This study introduces a novel approach using aerosol jet printing to fabricate e‐textiles with additive‐free aqueous Ti3C2Tx MXene inks. The flexible electrodes, systematically explored on cotton, polycotton, and polyester, exhibit remarkable areal capacitances of up to 4.4 F cm−2, achieving superior high‐rate performance, capacitance retention, and ...

Estimating aerosol emissions by assimilating observed aerosol optical depth in a global aerosol model [PDF]

Atmospheric Chemistry and Physics, 2012
Abstract. This study estimates the emission fluxes of a range of aerosol species and aerosol precursor at the global scale. These fluxes are estimated by assimilating daily total and fine mode aerosol optical depth (AOD) at 550 nm from the Moderate Resolution Imaging Spectroradiometer (MODIS) into a global aerosol model of intermediate complexity ...
