The agricultural sector is currently facing many global challenges, such as climate change, and environmental problems the release of pesticides fertilizers, which will be exacerbated in face population growth food shortages. Therefore, need to change traditional farming methods replace them with new technologies essential, application nanotechnology, especially green technology offers considerable promise alleviating these problems. Nanotechnology has led changes advances potential transform various fields sector, including biosensors, pesticides, packaging other areas industry. Due their unique properties, nanomaterials are considered suitable carriers for stabilizing fertilizers well facilitating controlled nutrient transfer increasing crop protection. production nanoparticles by physical chemical requires use hazardous materials, advanced equipment, a negative impact on environment. Thus, over last decade, research activities context nanotechnology have shifted towards environmentally friendly economically viable 'green' synthesis support industries. Green synthesis, part bio-inspired protocols, provides reliable sustainable biosynthesis wide range microorganisms rather than current synthetic processes. this field developing rapidly constantly being invented improve properties nanoparticles. In review, we consider latest innovations metal using different groups sectors achieve security, reduce pesticides. addition, mechanism advantages disadvantages compared common presented.

Transformation pathways and fate of engineered nanoparticles (ENPs) in distinct interactive environmental compartments: A review

Environment International, Год журнала: 2020, Номер 138, С. 105646 - 105646

Опубликована: Март 13, 2020

The ever increasing production and use of nano-enabled commercial products release the massive amount engineered nanoparticles (ENPs) in environment. An number recent studies have shown toxic effects ENPs on different organisms, raising concerns over nano-pollutants behavior fate various environmental compartments. After environment, interact with components environment undergoes dynamic transformation processes. This review focus transformations processes are interrelated to multiple aspects. Physical, chemical biological such as homo- or hetero-agglomeration, dissolution/sedimentation, adsorption, oxidation, reduction, sulfidation, photochemically biologically mediated reactions mainly occur consequently changes mobility bioavailability ENPs. Physico-chemical characteristics (particle size, surface area, zeta potential/surface charge, colloidal stability, core-shell composition) conditions (pH, ionic strength, organic inorganic colloids, temperature, etc.) most important parameters which regulated transformations. Meanwhile, organisms encountered transformed rather than pristine nanomaterials due their interactions materials other pollutants. Thus it is utmost importance study understand fate, bioavailability, mode toxicity.

Abstract Background Chronic and/or extreme stress in early life, often referred to as adversity, childhood trauma, or life stress, has been associated with a wide range of adverse effects on development. However, while linked negative number neural systems, the specific mechanisms through which influences development and individual differences children’s outcomes are still not well understood.

A candidate multi-epitope vaccine against SARS-CoV-2

Scientific Reports, Год журнала: 2020, Номер 10(1)

Опубликована: Июль 2, 2020

Abstract In the past two decades, 7 coronaviruses have infected human population, with major outbreaks caused by SARS-CoV and MERS-CoV in year 2002 2012, respectively. Currently, entire world is facing a pandemic of another coronavirus, SARS-CoV-2, high fatality rate. The spike glycoprotein SARS-CoV-2 mediates entry virus into host cell one most important antigenic determinants, making it potential candidate for vaccine. this study, we computationally designed multi-epitope vaccine using SARS-CoV-2. overall quality was validated silico Molecular Dynamics Simulation confirmed stability Docking studies revealed stable interactions Toll-Like Receptors MHC Receptors. cloning codon optimization supported proficient expression E. coli system. efficiency to trigger an effective immune response assessed simulation. computational analyses suggest that structurally which can induce specific responses thus, be against

A Comprehensive Review on Membrane Fouling: Mathematical Modelling, Prediction, Diagnosis, and Mitigation

Water, Год журнала: 2021, Номер 13(9), С. 1327 - 1327

Опубликована: Май 11, 2021

Membrane-based separation has gained increased popularity over the past few decades, particularly reverse osmosis (RO). A major impediment to improved performance of membrane processes, in general, is fouling. Fouling detrimental effects on membrane’s and integrity, as deposition accumulation foulants its surface and/or within pores leads a decline permeate flux, deterioration selectivity, permeability, well significantly reduced lifespan. Several factors influence fouling-propensity membrane, such morphology, roughness, hydrophobicity, material fabrication. Generally, fouling can be categorized into particulate, organic, inorganic, biofouling. Efficient prediction techniques diagnostics are integral for strategizing control, management, mitigation interventions minimize damage occurrences membranes. To improve antifouling characteristics RO membranes, enhancements by different chemical physical means have been extensively sought after. Moreover, research efforts directed towards synthesizing membranes using novel materials that would their performance. This paper presents review types, fouling-inducing factors, predictive methods, diagnostic techniques, strategies, with special focus

Variable Impacts of Climate Change on Blue Carbon

One Earth, Год журнала: 2020, Номер 3(2), С. 195 - 211

Опубликована: Авг. 1, 2020

Summary

Blue carbon provides opportunities to mitigate climate change while increasing ecosystem services for coastal communities, including adaptation; however, blue ecosystems are vulnerable change, leading uncertainties in the future efficacy of these ecosystems. In this review, we assess potential impacts on carbon. Despite uncertainties, sequestration is enhanced by landward migration habitats, maintenance sediment supply, restoration, and improved water quality. As an example, mangroves could result 1.5 Pg 2100. Mudflats, seaweed beds, swamp forests also contribute mitigation, although there large data gaps. Achieving full requires protection restoration facilitation changes distributions with actions that will deliver adaptation benefits. Conversely, worst-case squeeze scenario, losses 3.4 sequestered 2100 occur.
