The cell wall functions in plant heavy metal response

Ecotoxicology and Environmental Safety
Nonessential metals (e.g., cadmium (II), etc) and essential heavy metals (e.g., copper (II), etc) are both toxic for plants at high concentrations. The plant cell wall, which consists of pectin, cellulose, hemicellulose, lignin and proteins, acts as the ...

Heavy Molecular and Metallic Ions in the Magnetosphere

Space Science Reviews
AbstractObservations and present knowledge of heavy ions with mass ≥ 27 in the magnetosphere are reviewed. There are four ultimate sources of these heavy ions: the solar wind (mainly high charge-state atomic ions), the ionosphere (mainly molecular ions), the atmospheric metal layers that originate ultimately from ablation of meteoroids and possibly ...

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

Advanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction

Advanced Functional Materials, EarlyView.
A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2

Biosorption of heavy metal ions from contaminated wastewater: an eco-friendly approach

Green Chemistry Letters and Reviews
Several industries such as leather tanning, coal mining, steel and metal processing are responsible for heavy metals contamination in water. Heavy metals contamination in water can have harmful effects on both aquatic and terrestrial animals by entering ...

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high
