Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

open access: yesAdvanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Mapeamento do potencial de erosão laminar na bacia do rio Japaratuba, SE, via SIG Mapping the laminar erosion potential for the Japaratuba river basin, SE via GIS

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2011
A erosão do solo é a principal causa do empobrecimento precoce de terras produtivas e dentre as suas formas está a erosão laminar. Esta se caracteriza não apenas pela remoção de uma camada relativamente uniforme da superfície, mas também por seus ...

The effect of renovation of long-term temperate grassland on N2O emissions and N leaching from contrasting soils [PDF]

open access: yes, 2016
pre-printRenovation of long-term grassland is associated with a peak in soil organic N mineralisation which, coupled with diminished plant N uptake can lead to large gaseous and leaching N losses.

Food‐Based Edible Wireless Sensing Device with Isotropic Electromagnetic Response for Gastrointestinal Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
A sensor is fabricated that reflects electromagnetic waves wirelessly using only edible materials. The substrate is made of edible materials such as sugar and starch, and the electrodes are made of gold. This sensor has isotropic electromagnetic wave characteristics in response to rotation.

Spatiotemporal studies of black spruce forest soils and implications for the fate of C [PDF]

open access: yes, 2012
Post-fire storage of carbon (C) in organic-soil horizons was measured in one Canadian and three Alaskan chronosequences in black spruce forests, together spanning stand ages of nearly 200 yrs.

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.

Cover Crop Planting Date Trial [PDF]

open access: yes, 2011
When corn silage is harvested, the entire plant is removed, leaving the soil exposed throughout the winter. Many farmers have started planting cover crops following corn harvest because of increased soil health and fertility.
