Size-resolved particulate matter composition in Beijing during pollution and dust events [PDF]

open access: yes, 2006
Each spring, Beijing, China, experiences dust storms which cause high particulate matter concentrations. Beijing also has many anthropogenic sources of particulate matter including the large Capitol Steel Company. On the basis of measured size segregated,

Particulate matter dynamics

open access: yes, 2012
A substantial fraction of the particulate matter released into the atmosphere by industrial or natural processes corresponds to particles whose aerodynamic diameters are greater than 50 mm. It has been shown that, for these particles, the classical description of Gaussian plume diffusion processes, is inadequate to describe the transport and deposition.

Electrochemical Cell Designs for Efficient Carbon Dioxide Reduction and Water Electrolysis: Status and Perspectives

open access: yesAdvanced Materials, EarlyView.
This review discusses recent innovations in electrochemical CO2 reduction reactions (eCO2RR) and hydrogen evolution reaction cell designs. The latest advancements in in situ cells for operando characterization are also presented. Optimizations in flow patterns, membrane electrode assemblies, electrolyte engineering, and counter‐anodic reactions provide

Particulate matter dispersion and haze occurrence potential studies at a local palm oil mill. [PDF]

open access: yes, 2007
The emissions from palm oil industry through incineration and open burning are the major sources of air pollutions contribution in Malaysia. The consequence of increasing the particulate concentration, the particulate matter dissolves with vapour and ...

Facile Fabrication of Antibacterial 3D Fibrous Sponge via In Situ Protonation‐Induced Direct Electrospinning

open access: yesAdvanced Materials Interfaces, EarlyView.
This work introduces a versatile and straightforward approach for directly fabricating electrospun 3D nanofibrous sponge using a selection of solvents, avoiding potentially toxic additives or additional steps. The most important novelty in this study is a one‐step electrospinning process that simultaneously imparts three‐dimensionality and ...

Jamming and Stress Propagation in Particulate Matter

open access: yes, 1998
We present simple models of particulate materials whose mechanical integrity arises from a jamming process. We argue that such media are generically "fragile", that is, they are unable to support certain types of incremental loading without plastic ...

Air Pollution in the Valparaiso Area [PDF]

open access: yes, 2020
Volatile Organic Compounds (VOC’s) and particulate matter (PM) have been serious air pollution concerns around the world, particularly where industries and high volume traffic is present. These pollutants have been shown to have a negative effect on most

Organic carbon transport and C/N ratio variations in a large tropical river: Godavari as a case study, India [PDF]

open access: yes, 2005
This study gives an insight into the source of organic carbon and nitrogen in the Godavari river and its tributaries, the yield of organic carbon from the catchment, seasonal variability in their concentration and the ultimate flux of organic and ...

Particulate Matter and Human Health

open access: yes, 2021
This chapter provides an introduction to particulate matter by discussing various ways of categorisation, characterisation and their health effects. The natural and anthropogenic sources of atmospheric particulate matter are discussed. The chapter also introduces qualitatively some aerosol concepts, such as their chemical composition and size ...

Scaled‐Up Graphene Growth Through Chemical Vapor Deposition Over Large‐Area Liquid Cu Catalysts

open access: yesAdvanced Materials Interfaces, EarlyView.
Scaling up the catalyst area fivefold and improving molten catalyst cleaning minimize reactor kinetic effects, enabling reaction kinetics to dominate graphene growth. This results in high‐quality graphene with controlled layering and measurable nucleation rates.
