“…Hydrochar has been proven to be very effective in various industrial applications, especially in the adsorption of toxic substances from water, such as dyes, pigments, and heavy metals [3,13]. Various wastewater treatment processes, 2 of 19 including adsorption, membrane filtration, chemical precipitation, coagulation, ion exchange, electrochemistry, and electrochemical removal, can remove dyes and heavy metals from wastewater [14,15]. Some of these methods have substantial downsides, including high capital expenditure, high energy requirements, high maintenance and operation costs, partial removal, time-consuming regeneration, and the formation of toxic sludge [16,17].…”

In the present study, the ability for novel carbon microspheres (CMs) derived from date palm (Phoenix dactylifera) biomass using a hydrothermal carbonization (HTC) process and activated using phosphoric acid to remove methylene blue dye was investigated. Three types of palm-based wastes (seeds, leaflet, and inedible crystallized date palm molasses) were used and converted to CMs via the HTC process. The prepared samples were then activated using phosphoric acid via the incipient wetness impregnation method. The CMs samples before and after activation were analyzed using scanning electron microscopy (SEM), elemental analysis and scanning (CHNS), and the Fourier transform infrared (FTIR) and Brunauer–Emmet–Teller (BET) methods. The samples exhibited high BET surface areas after activation (1584 m2/g). The methylene blue adsorption results showed good fitting to the Langmuir, Fruendlich, and Temkin isotherm models for all activated samples. The maximum adsorption capacity achieved was 409.84 mg/g for activated CM obtained from the palm date molasses, indicating its high potential for application as a dye-based adsorption material.

This research investigates the transformative potential of nanotechnology in tending to water refinement challenges and advancing natural supportability. Carbon nanotubes and graphene were synthesized and joined into nanostructured channels, showing a well-defined arrangement with predominant basic keenness affirmed through SEM and XRD investigations. In comprehensive water decontamination tests, these channels showcased momentous efficiencies: overwhelming metals, such as lead (Pb) and cadmium (Cd), were expelled at rates outperforming 98% and 97%, individually; natural poison methylene blue displayed an amazing evacuation productivity surpassing 99.5%; microbial contaminant Escherichia coli was successfully killed, accomplishing a momentous expulsion effectiveness of 99.9%. Comparative investigations with related studies underscored the competitive or prevalent execution of the nanostructured channels. Additionally, a life cycle appraisal (LCA) highlighted the commitment to natural maintainability, uncovering generally moo nursery gas outflows (450 kg CO2e), vitality utilization (550 MJ), and asset consumption (10 kg) related to the filters’ whole life cycle. The inventive integration of nanotechnology into water treatment techniques exhibits the potential for effective, feasible, and intriguing approaches, laying the establishment for the advancement of progressed innovations fundamental for worldwide water resource conservation.

“…The unique characteristics and attributes of SiNPs are predominantly dependent on precursors and methods employed in their synthesis processes ( Jeelani et al., 2020 ). Presently, two strategies called top-to-down strategy and bottom-to-top strategy are mostly applied in the synthesis of NPs ( Figure 2 ; Vetchinkina et al., 2019 ; Salami et al., 2022 ). The top-to-down strategy indicates the breakdown of larger materials into smaller particles using methods such as physical milling and chemical decomposition.…”

Silicon (Si) is a widely recognized beneficial element in plants. With the emergence of nanotechnology in agriculture, silicon nanoparticles (SiNPs) demonstrate promising applicability in sustainable agriculture. Particularly, the application of SiNPs has proven to be a high-efficiency and cost-effective strategy for protecting plant against various biotic and abiotic stresses such as insect pests, pathogen diseases, metal stress, drought stress, and salt stress. To date, rapid progress has been made in unveiling the multiple functions and related mechanisms of SiNPs in promoting the sustainability of agricultural production in the recent decade, while a comprehensive summary is still lacking. Here, the review provides an up-to-date overview of the synthesis, uptake and translocation, and application of SiNPs in alleviating stresses aiming for the reasonable usage of SiNPs in nano-enabled agriculture. The major points are listed as following: (1) SiNPs can be synthesized by using physical, chemical, and biological (green synthesis) approaches, while green synthesis using agricultural wastes as raw materials is more suitable for large-scale production and recycling agriculture. (2) The uptake and translocation of SiNPs in plants differs significantly from that of Si, which is determined by plant factors and the properties of SiNPs. (3) Under stressful conditions, SiNPs can regulate plant stress acclimation at morphological, physiological, and molecular levels as growth stimulator; as well as deliver pesticides and plant growth regulating chemicals as nanocarrier, thereby enhancing plant growth and yield. (4) Several key issues deserve further investigation including effective approaches of SiNPs synthesis and modification, molecular basis of SiNPs-induced plant stress resistance, and systematic effects of SiNPs on agricultural ecosystem.
