Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Enhanced nitrate reduction by HPMC-stabilized nanoscale zero-valent iron (H-NZVI): Synthesis, characterization and reaction kinetics

Desalination and Water Treatment
Nano zero-valent iron (NZVI) was successfully stabilized by using hydroxypropyl methyl cellulose (HPMC). Systematic characterization observations (including XRD, TEM, FTIR, and VSM), as well as settling performance, illustrated that, compared to bare ...

Modified Biochar for Wastewater Nutrient Recovery and Slow‐Release Fertilization in Sandy Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Modified biochars are increasingly recognized as multifunctional materials for wastewater nutrient recovery and slow‐release fertilization in sandy agroecosystems. This review evaluates modified biochars, with particular emphasis on tyre‐derived biochar (TBC), for (i) recovery of nitrogen (N) and phosphorus (P) from wastewater and digestate ...

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

Small, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Environmental Remediation of TNT using Nanoscale Zero-Valent Iron Metal

, 2009
This research focused on the use of nanoscale zero-valent iron (NZVI) to remediate trinitrotoluene (TNT). Zero-valent iron has demonstrated effective degradation of TNT, however, these particles themselves have significant problems in treating sorbed ...

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Liquid Nitrogen Activation of Zero-Valent Iron and Its Enhanced Cr(VI) Removal Performance

, 2019
In this study, we report that liquid nitrogen treatment is a promising zero-valent iron activation method that does not remove the iron oxide shell; this can improve the apparent Cr­(VI) removal rate constant of zero-valent iron by about 4–120 times ...

Dimensionality‐Driven Carbon Reconstruction Activates MXene Quantum Dots for Dechlorination

Small, EarlyView.
Finite Ti2CO2${\rm Ti}_2{\rm CO}_2$ MXene quantum dots exhibit a reconstruction‐induced activation mechanism absent in extended two‐dimensional MXenes. Carbon‐sublattice reconstruction generates electronically active motifs that facilitate charge redistribution and promote dechlorination of chlorinated hydrocarbons, revealing a new route for activating
