Coordinated Sampling of Microorganisms Over Freshwater and Saltwater Environments Using an Unmanned Surface Vehicle (USV) and a Small Unmanned Aircraft System (sUAS)

open access: yesFrontiers in Microbiology, 2018
Biological aerosols (bioaerosols) are ubiquitous in terrestrial and aquatic environments and may influence cloud formation and precipitation processes. Little is known about the aerosolization and transport of bioaerosols from aquatic environments.

The Concentrations and Reduction of Airborne Particulate Matter (PM10, PM2.5, PM1) at Shelterbelt Site in Beijing

open access: yesAtmosphere, 2015
Particulate matter is a serious source of air pollution in urban areas, where it exerts adverse effects on human health. This article focuses on the study of subduction of shelterbelts for atmospheric particulates.

Elemental and isotopic compositions in blank filters collecting atmospheric particulates

open access: yesJournal of Analytical Science and Technology, 2021
Background The atmospheric particulates can be harmful to human health due to toxic substances sorbed onto particulates. Although the atmospheric particulates have been collected using different types of filters, few studies have reported background ...

Non-Einstein Viscosity Phenomenon of Acrylonitrile–Butadiene–Styrene Composites Containing Lignin–Polycaprolactone Particulates Highly Dispersed by High-Shear Stress

open access: yes, 2019
Lignin powder was modified via ring-opening polymerization of caprolactone to form a lignin–polycaprolactone (LPCL) particulate. The LPCL particulates were mixed with an acrylonitrile–butadiene–styrene (ABS) matrix at an extremely high rotational speed ...

Development and characterisation of lithographically printed voltaic cells [PDF]

open access: yes, 2006
This paper reports progress in the fabrication of voltaic cells and batteries via offset lithographic printing. Successful design and manufacture of lithographically printed voltaic cells would facilitate the integration of printed passive components ...

Examination of silver-graphite lithographically printed resistive strain sensors [PDF]

open access: yes, 2006
This paper reports the design and manufacture of three differing types of resistive strain sensitive structures fabricated using the Conductive Lithographic Film (CLF) printing process. The structures, utilising two inks prepared with silver and graphite

Particulate Mercury and Particulate Organic Matter in the Itenez Basin (Bolivia) [PDF]

open access: yesApplied Sciences, 2020
In rivers and other freshwater bodies, the presence of mercury can be due to direct contamination by anthropic activities such as gold mining. However, it can also be attributed to atmospheric deposition and erosion, runoff, or lixiviation from surrounding soils.

Light attenuation characteristics of glacially-fed lakes [PDF]

open access: yes, 2014
Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes.

Theory and simulation of spectral line broadening by exoplanetary atmospheric haze

open access: yes, 2018
Atmospheric haze is the leading candidate for the flattening of expolanetary spectra, as it's also an important source of opacity in the atmospheres of solar system planets, satellites, and comets.

Particulate collector

open access: yes, 2008
The goal of this work was to manufacture and to analyze a passive device performance (inertial collector). This one has worked as an opening for the inside ambient natural airing and also it retains some particulate material present in the air which passes through it. The collector work has been based in the inertia which each particle has, that is, as
