A Reusable Polymeric Sensor Based on Green‐Synthesized CQDs@ZIF‐8 for the Rapid Detection of Nitro‐Explosive Picric Acid

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents the rational design and synthesis of a highly luminescent polymeric nanocomposite. Initially, highly fluorescent carbon quantum dots (CQDs) are synthesized via a facile hydrothermal method using citric acid and β‐alanine as precursors, followed by rigorous purification through centrifugation and filtration.

Managing Agricultural Soils of Pakistan for Food and Climate

open access: yesSoil & Environment, 2018
Pakistan; a predominantly arid land region; has a large, growing, urbanizing and increasingly affluent population. Soil and water resources are finite, with per capita arable land area of 0.10 ha by 2050, and prone to degradation by inappropriate ...

Issues Related to Incorporating Northern Peatlands into Global Climate Models [PDF]

open access: yes, 2009
Northern peatlands cover ~3–4 million km2 (~10% of the land north of 45°N) and contain ~200–400 Pg carbon (~10–20% of total global soil carbon), almost entirely as peat (organic soil).

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

open access: yesAdvanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Basic principles for sampling and reporting for studies involving the measurement of carbon sequestration in soils : [Abstract 588] [PDF]

open access: yes, 2008
Variation in soil organic carbon (SOC) levels due to differences in soil management has been the subject of much investigation over the past decades. More recently, growing concerns relating to the consequences of increasing carbon dioxide levels in the ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water [PDF]

open access: yes, 2009
Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size ...

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Environmental aging enhanced the ability of biochar to remediate heavy metal-contaminated soil through combined adsorption and microbial community regulation: A mechanistic analysisMendeley data

open access: yesIndustrial Crops and Products
The remediation of heavy metal-contaminated soils via biochar involves both adsorption and microbial community regulation, yet the impact of environmental aging on this synergistic mechanism remains unclear.
