"Nano", which derives from the Latin word nanus and means dwarf, refers to a very small unit of measurement equal one billionth meter. Nanotechnology, deals with manipulation matter at atomic molecular level, has an application area in animal husbandry as well many fields. Nano-sized feed additives, have come forefront livestock sector recent years, become innovative used increase nutritional value feeds optimize health performance. Since these additives are nano-sized particles increased specific surface area, they can positive effect on number factors such digestibility, nutrient absorption, immune system, growth development. Minerals form nanoparticles bioavailability by passing through intestinal wall body cells faster compared larger particles. The nano level substance not only increases productivity animals, but also brings potential improve functionality molecules. Nano digestion absorption feed, allowing animals benefit more effectively. However, there several challenges associated this approach. These include for endotoxin production, reduced due interaction natural nutrients, possibility nanoparticle accumulation body, risks, ethical considerations, environmental concerns some negative effects interference nutrients that be avoided encapsulation. This article discusses studies offer benefits nutrition.

The biochemical and growth-associated traits of basil (Ocimum basilicum L.) affected by silver nanoparticles and silver

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Feb. 6, 2024

Abstract Background The biochemical and growth changes resulting from exposure of basil ( Ocimum basilicum L.) seedlings to silver nanoparticles were investigated. Over a two-week period, exposed different concentrations (0, 40, 80 ppm) silver. Results Our findings revealed that at 40 ppm, both nitrate led decreased weight, root shoot length, as well chlorophyll b content. Conversely, these treatments triggered an increase in key properties, such total phenols, carotenoids anthocyanins, with showing more pronounced effect compared nitrate. Moreover, the levels malondialdehyde (MDA) hydrogen peroxide (H 2 O ) rose proportionally treatment concentration, nanoparticle exhibiting substantial increase. Silver content showed significant upswing roots leaves increased. Conclusions Application varying on plants resulted reduced lower content, while simultaneously boosting production antioxidant compounds. Notably, anthocyanin, carotenoid, phenol increased significantly. However, despite this activity, plant remained unable fully mitigate oxidative stress induced by nanoparticles.

In this study, lead-free BiM2+(Zn, Ca, Mg)Ti–BiFeO3 ceramics are fabricated under eco-friendly hydrothermal reaction conditions at 250 °C. XRD patterns show that all the synthesized compounds exhibit a phase coexistence of monoclinic and tetragonal perovskite-type structures with morphotropic boundary x = 0.4, minimum impurity. The calculated average crystallite/grain size samples was close to 50 nm full width half-maximum main peak. corresponding bonds constituent elements were observed by FTIR analysis, which further supports formation local structure. EDS analyses detect elements, their quantities, compositional homogeneity. SEM data agglomerated nearly spherical morphology an particle about 128 nm. All ceramic powders revealed thermal stability trivial mass loss up investigated high temperatures (1000 οC). dielectric constant reached its maximum 38.7 MHz finally remained after 80 for nanoceramics. Because complementary impact different compositions, most effective piezoelectric characteristics d33 136 pCN–1, Pr 8.6 pCN–1 cm–2, kp 11% 30 °C attained 0.4 content 0.4BiCaTi–0.6BiFeO3 ceramic. measured magnetic hysteresis (M–H curve) showed weak ferromagnetic nature highest moment ∼0.23 emu/g 0.4BiCaTi–0.6BiFeO3, other exhibited negligible diamagnetic transition. optical response study shows 0.4BiMgTi–0.6BiFeO3 sample yielded maximal transmittance (50%), whereas compound refractive index. large band gap insulating or nature. Our findings demonstrate BiM2+Ti–BiFeO3 system, using low-temperature technique, is excellent multiferroic nanoceramic.
