Abstract
Under a changing climate, keeping the food supply steady for an ever-increasing population will require crop plants adapted to environmental fluctuations. Genetic engineering and genome-editing approaches have been used for developing climate-resilient crops. However, genetically modified crops have yet to be widely accepted, especially for small-scale farmers in low-income countries and some societies. Nano-priming (seed exposure to nanoparticles, NPs) has appeared as an alternative to the abovementioned techniques. This technique improves seed germination speed, promotes seedlings' vigor, and enhances plant tolerance to adverse conditions such as drought, salinity, temperature, and flooding, which may occur under extreme weather conditions. Moreover, nano-enabled seed treatment can increase the disease resistance of crops by boosting immunity, which will reduce the use of pesticides. This unsophisticated, farmer-available, cost-effective, and environment-friendly seed treatment approach may help crop plants fight climate change challenges. This review discusses the previous information about nano-enabled seed treatment for enhancing plant tolerance to abiotic stresses and increasing disease resistance. Current knowledge about the mechanisms underlying nanomaterial-seed interactions is discussed. To conclude, the review includes research questions to address before this technique reaches its full potential.

Abstract
Excess fluoride ions in groundwater accumulate through the roots of crops, affecting photosynthesis and inhibiting their growth. Long-term bioaccumulation also threatens human health because it is poorly degradable and toxic. Currently, one of the biggest challenges is developing a unique material that can efficiently remove fluoride ions from the environment. The excellent properties of functionalized pillar[5]arene polymer-filled nanochannel membranes were explored to address this challenge. Constructing a multistage porous nanochannel membrane, consisting of microscale etched nanochannels and nanoscale pillar[5]arene cross-linked polymer voids. A fluoride removal rate of 0.0088 mmol ⋅ L-1 ⋅ min-1 was achieved. Notably, this rate surpassed the rates observed with other control ions by a factor of 6 to 8.8. Our research provides a new direction for developing water fluoride ion removal materials.

Abstract
In order to find new greener solutions for iron (Fe) induced chlorosis, two new chelating agents, N,N-dihydroxy-N,N'-diisopropylhexanediamide (DPH) and Azotochelin (AZO), were assessed for its effectiveness in mending induced chlorosis in soybean (Glycine max). DPH-Fe and AZO-Fe complexes were firstly tested for their soil interactions and capability to maintain Fe in a bioavailable form. Secondly, 57Fe-chelates of DPH and AZO were applied to the soil in a pot experiment with chlorotic soybean plants. Their growth, SPAD chlorophyll index, and the Fe concentration in plant tissues and the remaining soil were evaluated. An isotope deconvolution analysis by using the concentration of the Fe isotopes was used to distinguish the Fe coming from soil and from the 57Fe labelled fertilizer treatments. AZO and DPH have shown different interactions with soil and its components, with AZO showing less interaction than DPH. The application of AZO and DPH resulted in SPAD increase and Fe content. However, it was found that the Fe in plants had not come from the fertilizer application, but instead from natural sources. This is likely due to dissolution phenomena aided by the chelates added. Overall, AZO and DPH have shown good results in amending Fe induced chlorosis in calcareous soils and for this reason should be regarded as good green-candidates for Fe plant nutrition in calcareous soils.
