Nano particles have gained special attention in recent years due to their remarkable electrical, magnetic, optical, and mechanical capabilities, and they offer a variety of uses in all sectors of engineering. Gold nanoparticles, for instance, are catalytic when they are 10 nm in size, whereas nanoparticles with a short radius of curvature and angular forms have better catalytic capabilities. Co-precipitation nanoparticle production is a simple approach that results in a wide range of nanoparticle sizes. Top-down and bottom-up techniques used to create mono-dispersed spherical bismuth (Bi) NPs. These Nanoparticles have outstanding colloidal characteristics. Sputtering is the technique for creating NPs that involves hitting solid surfaces with the high energy particles like gas or plasma. In an aqueous solution, gold nanoparticles were created by using a laser ablation approach. A zeta potentiometer is often used to assess surface charges and their dispersal constancy in a solution. Several industry and technology sectors, including IT, medicine, energy, transportation, homeland security, food safety, and environmental research, are being significantly improved, if not revolutionized, by nano-technology.
Copper nanoparticles are typically in black or brown powder form. Copper nanoparticles uses in heat exchange systems, bioscience, anti-microbial materials, Aluminum is extremely harmful to fish in the acid conditions. The primary targeted organ of fish is gill, and death is influenced by a variety of respiratory, osmo-regulatory, and ion regulatory dysfunction. To understand the effect of heavy metals on the aquatic biota, it is necessary to characterize the methods readily accessible to aquatic species for heavy metal mobility, immobilization, and excretion. The severe Ag toxicity to fish is very lower in the sea-water than in the freshwater. Tetrodotoxin is a highly poisonous toxin located primarily in gonads and liver of some fishes, including pufferfishes, toadfish and globefish as well as some shellfish, octopus, and amphibian species. Fish exposed to Cr for the first time displayed a variety of behavioural alterations, including loss of appetite, irregular swimming, changing in colour and mucous discharge. It is much more complicated than genome of humans because zebrafish possess two more sets of chromosomes than humans. Glutathione peroxidase and Catalase are anti - oxidant enzymes that have long been used to assess anti-oxidant injury and stress reaction.
Nano-pesticides are essential for the successful and sustainable management of different pests, and they can decrease the use of agrochemicals, thereby mitigating current environmental dangers. Nevertheless, advancements in nano-particles or micro-particles, as well as distribution models for biolistic gene delivery in various plants, are still needed to enhance grain growth and crop and plant protection. , seed priming is being used effectively to expedite and synchronize germination, increase seedling vigor, and make plants extra resilient to various biotic and abiotic stresses, resulting in increased efficiency and quality of food. Nano fertilizers have distinct properties like mega absorption, increase in production, enhanced activity of photosynthesis, and a substantial improvement in leaf surface area. Growth of plants is changed to a particular environment conditions at different phases of development; and hence, a proper choice of planting date increases photosynthesis efficacy. In this perspective, providing carbon nano-tubes in to the chloroplasts has resulted in a progress for plants' enhanced capacity to collect more energy from the sun. Lower rates of photosynthetic activity in the crop plants under the cold stress limited metabolic pathways for Carbon assimilation.
Wheat (Triticum aestivum L.) is one of the important crops of human diet around the globe. Purify flour of wheat contains less vitamins and causes constipation and malnourishment. The experiment was designed to study on wheat crop, botanical and agricultural parameters and advances in plant sciences and accomplished in Randomized Complete Block Design. Sowing was done in field with plot size of 216 m2. LAI is very crucial growth index which directly controls the interception of solar radiation and consequently dry matter production and accumulation. The LAD exhibits the tenacity of leaves to remain photo synthetically active during the growth season of a crop. The NAR indicates the dry matter accumulation in plants per unit canopy area. Recorded data was subjected to analysis of variance by using Statistix 8.1 software. It presented mean values of all treatments for crop growth rate. Maximum results for CGR observed under T3 with 14.3 mean values. While minimum observations had been shown by T1 that is 13.4. It showed mean values for all applied treatments and wheat showed maximum value of leaf area index of (3.3367) under treatment (T4) and minimum value of leaf area index that is 3.0233 was shown by plants under treatment (T7). Maximum results for flag leaf area observed under T4 with 114.73 mean values. While minimum observations had been shown by T1 that is 88.03. It is recommended that the farmers should use split dose of potassium fertilizer for better growth and yield of wheat and it may also be helpful in future prospects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
