Optical Characterization of Fresh and Photochemically Aged Aerosols Emitted from Laboratory Siberian Peat Burning

, 2022
Carbonaceous aerosols emitted from biomass burning influence radiative forcing and climate change. Of particular interest are emissions from high-latitude peat burning because amplified climate change makes the large carbon mass stored in these peatlands

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

Advanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Application of a gas-jet system to investigations of environmental aerosols

, 1986
The so-called gas-jet technique is widely used in nuclear physics for fast on-line transportation of short-lived nuclides. Nuclear reaction products recoiling from the target are thermalized in a gas volume doped with artificial aerosols such as salt ...

Energy Recovery Ventilation: What Is Needed to Fill the Research Gaps Related to Its Effects on Exposure to Indoor Bio-Aerosols, Nanoparticulate, and Gaseous Indoor Air Pollution

Atmosphere
Indoor air quality (IAQ) impacts human health, productivity, and well-being. As buildings become more energy-efficient and tightly sealed, the need for effective ventilation systems that maintain adequate IAQ grows.

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

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 ...

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

Hydro‐ and Lipophilicity of Molecular‐Size‐Controlled Hydrogel Drug Carriers

Advanced Materials Technologies, EarlyView.
We investigate nano‐sized hydrogel drug carriers with tailored hydro‐ and lipophilicity. We design their encapsulation and structure‐forming capabilities and follow them in real time during fabrication using time‐resolved and in situ grazing incidence x‐ray scattering.

Aerosol Jet Printing of Benzocyclobutene as a Thermally Stable, Low‐Loss Dielectric for Multilayer Microwave Electronics

Advanced Materials Technologies, EarlyView.
Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
