Use of electrochemical sensors for measurement of air pollution: correcting interference response and validating measurements [PDF]

Atmospheric Measurement Techniques, 2017
The environments in which we live, work, and play are subject to enormous variability in air pollutant concentrations. To adequately characterize air quality (AQ), measurements must be fast (real time), scalable, and reliable (with known accuracy ...

Specifying the light-absorbing properties of aerosol particles in fresh snow samples, collected at the Environmental Research Station Schneefernerhaus (UFS), Zugspitze [PDF]

Atmospheric Chemistry and Physics, 2019
Atmospheric aerosol particles like mineral dust, volcanic ash and combustion particles can reduce Earth's snow and ice albedo considerably even by very small amounts of deposited particle mass. In this study, a new laboratory method is applied to measure

Counting on chemistry: laboratory evaluation of seed-material-dependent detection efficiencies of ultrafine condensation particle counters [PDF]

Atmospheric Measurement Techniques, 2020
Condensation particle counters (CPCs) are crucial instruments for detecting sub-10 nm aerosol particles. Understanding the detection performance of a CPC requires thorough characterization under well-controlled laboratory conditions.

Effects of cleaning spray use on eyes, airways, and ergonomic load

BMC Public Health, 2023
Background Cleaning workers are exposed to chemicals and high physical workload, commonly resulting in airway problems and pain. In this study the response in the upper airways and the physical workload following airborne and ergonomic exposure of ...

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

Advanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

Advanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.
