Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

open access: yesAdvanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Do long-term applications of organic residues promote copper ecotoxicity in soil? [PDF]

open access: yes, 2019
Amendments with organic residues (OR) are a major source of copper (Cu) contamination in agricultural soils. The chronic soil contamination with Cu raises the problem of potential toxic effects of Cu on soil organisms and then the long-term ...

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 ...

Root-induced decrease in metal binding capacity of dissolved organic matters in the rhizosphere: evidences from two convergent studies : S10.01b -1 [PDF]

open access: yes, 2012
The parallel understanding of dissolved organic matters (DOM) impact on trace metal speciation in soil and root ability to change DOM concentration and composition in the rhizosphere strongly suggests a substantial alteration of metal binding capacity of

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Sensitivity of tuberous roots crops to salinity in a protected environment

open access: yesRevista de Ciências Agroveterinárias, 2022
Soil salinity has been a limiting barrier for the production of vegetables in protected environments. Thus, the understanding of the sensitivity of species to this stress factor must be explored, seeking better growing conditions.
