It has been suggested, but not previously measured, that dissolution kinetics of soluble nanoparticles such as CuO (NPs) in soil affect their phytotoxicity. An added complexity is also affected by the presence plant roots. Here, we measured rate NPs bulk soil, and which wheat plants (Triticum aestivum) were grown under two NP dosing conditions: (a) freshly (500 mg Cu/kg soil) (b) aged for 28 d before planting. At end growth period (14 d), available Cu was three different compartments: (not...
Abstract Noble metal nanoparticles are promising catalysts in electrochemical reactions, while understanding the relationship between structure and reactivity of particles is important to achieve higher efficiency electrocatalysis, promote development single‐molecule electrochemistry. Electrogenerated chemiluminescence (ECL) was employed image catalytic oxidation luminophore at single Au, Pt, Au‐Pt Janus nanoparticles. Compared monometal nanoparticles, particle exhibited enhanced ECL...
Abstract One important goal of the current electrocatalysis is to develop integrated electrodes from atomic level design multilevel structural engineering in simple ways and low prices. Here, a series oxygen micro‐alloyed high‐entropy alloys (O‐HEAs) developed via metallurgy approach. A (CrFeCoNi) 97 O 3 bulk O‐HEA shows exceptional electrocatalytic performance for evolution reaction (OER), reaching an overpotential as 196 mV Tafel slope 29 dec −1 , with stability longer than 120 h 1 m KOH...
Climate change is increasing the severity and length of heat waves. Heat stress limits crop productivity can make plants more sensitive to other biotic abiotic stresses. New methods for managing are needed. Herein, we have developed ∼30 nm diameter poly(acrylic acid)-block-poly(N-isopropylacrylamide) (PAA-b-PNIPAm) star polymers with varying block ratios temperature-programmed release a model antimicrobial agent (crystal violet, CV) at plant-relevant pH. Hyperspectral-Enhanced Dark field...
As the benchmark anode material for sodium-ion batteries, hard carbon (HC) is still confronted by unsatisfactory initial Coulombic efficiency and an unstable solid electrolyte interphase (SEI), which degrade energy density cycling performance. Herein, we demonstrate first-time application of sodium alkoxyaluminum hydride (RA) as a bifunctional presodiation reagent HC electrode. By driving homogeneous accommodation Na into electrode concurrently inducing formation passivative Al2O3 nanolayer,...
Managing the risks of manufactured nanomaterials requires ability to accurately and reproducibly measure physical chemical properties these materials that are relevant their risk assessment. However, many non-equilibrium system-dependent behaviors challenge conventional characterization methods used characterize them. New modifications being developed address some shortcomings. Here, we critically review progress towards standardization validation assess health safety risks. The limitations...
The objectives of this research were to quantify the impact organic matter content, soil pH and moisture content on dissolution rate solubility copper oxide nanoparticles (CuO NPs) in soil, develop an empirical model predict kinetics CuO NPs soil. dosed into standard LUFA soils with various carbon content. Chemical extractions applied measure NP kinetics. Doubling reactive 2.1 increased 2.7-fold but did not change constant. Increasing from 5.9 6.8 2.2 decreased constant 0.56 mol1/3·kg1/3·s–1...
The application of nanoparticles (NPs) to soils, as either fertilizers or fungicides (e.g., CuO NPs), has been proposed improve the sustainability agriculture. observed effects could result directly from NP–plant interactions indirectly through on soil microbiome. objective this study was assess NPs changes in bacterial community structure and nitrogen-cycling-associated functions a high pH correlate these with nitrate accumulation, parameter changes, plant growth over 28 days. Triticum...
Here, a single-track CoCrFeMnNi high entropy alloy(HEA) was prepared by laser melting deposition. The microstructural evolution of columnar to equiaxed transition experimentally observed across the molten pool. temperature gradient and solidification rate were theoretically calculated finite element model via numerical simulation. Combining experimental observations simulations, map established quantitatively reveal underlying correlation between parameters morphology. A decrease in ratio...
Foods contaminated by foodborne pathogens have always been a great threat to human life. Herein, we constructed an electrochemical immunosensor for Salmonella detection using Fe3O4@graphene modified electrode. Because of the excellent electrical conductivity and mechanical stability graphene large specific surface area Fe3O4, nanocomposite exhibits signal, which greatly increased sensitivity immunosensor. Gold nanoparticles were deposited on technology immobilization antibody. Cyclic...
Pesticide nanoencapsulation and its foliar application are promising approaches for improving the efficiency of current pesticide practices, whose losses can reach 99%. Here, we investigated uptake translocation azoxystrobin, a systemic pesticide, encapsulated within porous hollow silica nanoparticles (PHSNs) mean diameter 253 ± 73 nm, following on tomato plants. The PHSNs had 67% loading azoxystrobin enabled controlled release over several days. Thus, nanoencapsulated was taken up...
The effects of different concentrations (10-7 to 10-2 M) cadmium chloride on root growth, cell division and nucleoli in tip cells Allium sativum L. were investigated. At lower Cd2+ 10-6 M), did not influence the even had a stimulation during short treatment. results showed that rate growth per day at treatment groups (10-4 M Cd2+) decreased with increasing duration concentration. induced c-mitosis, anaphase bridges, chromosome stickiness nucleoli, causing some particles similar...

Nanoparticles composed of ZnO encapsulated in a mesoporous SiO2 shell (nZnO@SiO2) with primary particle diameter ∼70 nm were synthesized for delivery Zn, micronutrient, by foliar uptake. Compared to the rapid dissolution bare nZnO (90% Zn after 4 h) model plant media (pH = 5), nZnO@SiO2 released more slowly (40% 3 weeks), thus enabling sustained over longer period. nZnO@SiO2, nZnO, and ZnCl2 exposed Solanum lycopersicum dosing 40 μg micronutrient (in 20 μL suspension) on single leaf.
