Comprehensive Investigation of Iron Salt Effects on Membrane Bioreactor from Perspective of Controlling Iron Leakage

open access: yesMembranes
Although adding iron salts can improve phosphorus removal in membrane bioreactor (MBR) processes, overdosing iron salts may result in excessive iron concentrations in the effluent and pose risks of surface water contamination. In this study, an optimized

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

High single-pass conversion of nitrous oxide to dinitrogen in gas-diffusion-electrolyzer

open access: yesNature Communications
Electrocatalytic N2O reduction reaction offers a sustainable solution of converting greenhouse gas N2O to N2 under ambient conditions, but achieving high single-pass conversion remains challenging.

Water Quality Trading: Theoretical and Practical Approaches [PDF]

open access: yes
Permit trading as an instrument to control air pollution has already been implemented in several countries, so in Europe since 2005. Could this instrument, however, also be adequately used for water pollution control of river basins in form of a water ...

Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding

open access: yesAdvanced Functional Materials, EarlyView.
A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...

CONTRACTING FOR NONPOINT-SOURCE POLLUTION ABATEMENT [PDF]

open access: yes
This study presents an incentive scheme to control agricultural nonpoint-source pollution. The analysis is based on a principal-agent framework with two parties: farmers and a regulating authority.

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

High Pressure Densification Investigation of Li3PS4 and Li6PS5Cl Solid Electrolytes using Combine X‐Ray Diffraction, X‐Ray Absorption Tomography and Ionic Measurement

open access: yesAdvanced Functional Materials, EarlyView.
We used multiple analytical techniques at the Psiché beamline, Synchrotron Soleil, and at D20 instrument in Institut Laue Langevin, to study the densification of thiophosphate solid electrolytes Li3PS4 and Li6PS5Cl. Our combined X‐ray diffraction, absorption tomography, absorption density, neutron power diffraction, and ionic conductivity analyses ...

Sabatier‐Adjusted d‐Band Centers of Scalable Asymmetric Iron Sites toward Dynamic Nonradical Network for Fast Mineralization with Low‐Amount Oxidant

open access: yesAdvanced Science
Nonradicals relying on peroxymonosulfate (PMS) activation face inherent kinetic and thermodynamic limitations in pollutant mineralization. This is overcome using asymmetric iron single‐atom catalysts (Fe‐SACs) with Sabatier‐adjusted d‐band centers that ...

Environmental Games and Queue Models [PDF]

open access: yes
This paper considers a pollution and control game which uses a queuing framework. This framework allows an accounting of pollution events, environmental pollution quality and the application of controls to maintain a desirable quality of the environment.
