Techniques for measuring atmospheric aerosols at the High Resolution Fly's Eye experiment

open access: yes, 2005
We describe several techniques developed by the High Resolution Fly's Eye experiment for measuring aerosol vertical optical depth, aerosol horizontal attenuation length, and aerosol phase function.

A global perspective on aerosol from low-volatility organic compounds [PDF]

open access: yes, 2010
Global production of organic aerosol from primary emissions of semivolatile (SVOCs) and intermediate (IVOCs) volatility organic compounds is estimated using the global chemical transport model, GEOS-Chem. SVOC oxidation is predicted to be a larger global

Development of an Electron Emitter via Seamless Shaping of a 3D‐Printed Ceramic Cone With Carbon Nanotube Mesh Film as an Alternative to Polymer‐Based Materials

open access: yesAdvanced Materials Technologies, EarlyView.
This paper focuses on electron emitters formed using seamless hybrid shaping of the ceramic 3D‐printed cone (as a supporting structure) and a conductive emitting film obtained from the suspension of dispersed carbon nanotubes. 3D printing enables freedom to design and forming the emitter tip shape and angle to tune the performance of the emitter ...

Extreme High‐Speed Laser Material Application‐Coated Carbide‐Reinforced Control Plates and Conventional Lead‐Based Plates in Axial Piston Machines

open access: yesChemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023
In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Aerosols in the mortuary. [PDF]

open access: yesJournal of Clinical Pathology, 1983
Air counts in seven mortuaries during necropsies revealed that providing care is taken with washing intestines and close dissection, bacterial numbers are often less than those found in an operating theatre, and relate more to the number of people and movement in the room than the work.

Substantial convection and precipitation enhancements by ultrafine aerosol particles

open access: yesScience, 2018
Up with ultrafine aerosol particles Ultrafine aerosol particles (smaller than 50 nanometers in diameter) have been thought to be too small to affect cloud formation. Fan et al. show that this is not the case.

Aerosol Jet Printing of Superhydrophobic Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Hydrophilic Chitosan Derivatives: Synthesis and Applications

open access: yesChemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022
A benign and low‐cost alternative for fossil‐fuel‐sourced polymers, chitosan has tremendous potential because of its bioactivity, biocompatibility, biodegradability, and low toxicity. Synthetic pathways for chitosan derivatives with improved water solubility, and their associated applications, are explored. With the change in global direction towards a

A comprehensive parameterization of heterogeneous ice nucleation of dust surrogate: laboratory study with hematite particles and its application to atmospheric models [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
A new heterogeneous ice nucleation parameterization that covers a wide temperature range (−36 to −78 °C) is presented. Developing and testing such an ice nucleation parameterization, which is constrained through identical experimental conditions, is ...
