Comparison of soil heavy metal pollution caused by e-waste recycling activities and traditional industrial operations

, 2017
The traditional industrial operations are well recognized as an important source of heavy metal pollution, while that caused by the e-waste recycling activities, which have sprouted in some developing countries, is often overlooked.

Endogenous Environmental Policy when Pollution is Transboundary [PDF]

We analyze the formation of environmental policy to regulate transboundary pollution if governments are self-interested. In a common agency framework, we portray the environmental policy calculus of two political supportmaximizing governments that are in

Retreaded tires are an overlooked source of microplastics with distinct additive leaching and ecotoxicity

Communications Earth & Environment
Retreaded tires constitute a substantial segment of the commercial tire market and are an important source of tire wear particles (TWPs), yet the environmental risks of this major microplastic category remain uninvestigated.

Non‐Additive Criteria Assessment in Sustainability Evaluation of High Entropy Alloys: A Toxicity‐Weighted Framework

Advanced Engineering Materials, EarlyView.
Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Reactive aldehyde chemistry explains the missing source of hydroxyl radicals

Nature Communications
Hydroxyl radicals (OH) determine the tropospheric self-cleansing capacity, thus regulating air quality and climate. However, the state-of-the-art mechanisms still underestimate OH at low nitrogen oxide and high volatile organic compound regimes even ...

Strategies of selective electroreduction of aqueous nitrate to N2 in chloride-free system: A critical review

Green Energy & Environment
Electroreduction of nitrate has been gaining wide attention in recent years owing to it's beneficial for converting nitrate into benign N2 from the perspective of electrocatalytic denitrification or into value-added ammonia from the perspective of ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Modulating biochar compositions to maximize synergy between contaminant binding and transformation: the critical role of carbonates and implications for in situ groundwater remediation

Biochar
Dealing with groundwater impacted by persistent, low-concentration chlorinated solvents is a major challenge for site remediation, as technologies designed for fast contaminant removal or destruction often are not cost-effective.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
