This strategy to materialize nanocellulose provides an outlook for the future perspectives in overcoming the global issues like stubble burning, curbing air pollution etc. in a facile manner.Increasing population pressure and decreasing cultivable land brought the agricultural sector at an alarming situation of food production particularly in the developing countries. To feed the burgeoning population, the agriculture sector needs to become more productive and diversified while facing the adversity of climate change and limitations of natural resources. During 1960-70, the improved irrigation facilities, the use of fertilizers and pesticides in the cultivation of high yielding varieties of cereals successfully led to the Green revolution in India. In the present scenario, the low irrigation and fertilizer use efficiencies, poor pesticide application and delivery are amongst the important issues in developing countries that need to be addressed for getting higher productivity. Also, fertilizer and pesticide usage also had severe associated environmental consequences like eutrophication, resistance and resurgence in pest, toxicity to non-target organisms, residues in food and feed, accumulation in the environment, etc. In such conditions, organic farming, a traditional practice coupled with the exploration of bio-nanoparticles to achieve a sustainable production system seems to be a better option. This review focuses on current research developments in the areas of bio-nano-enabled crop nutrition, protection, post-harvest management, and the possibility of bio-nanomaterials and organic farming confluence to revolutionize the agricultural sector by ensuring sustainable food security for coming generations.Glycyrrhiza glabra Linn (Fabaceae), commonly known as Licorice/Liquorice, Mulahatti; is an undershrub. The dried, peeled or unpeeled underground stems and roots are used for the treatment of upper respiratory tract ailments, immunodeficiency, endocrine disorders, skin, liver, joint and heart diseases. Medicinal properties of this plant are enormous and offer it as one of the greatest candidates in the field of Nanomedicine. The Nanomedicine has dedicated to safeguard and upgrade human health using the nanotechnology. Bioactive constituents of this plant perform versatile pharmacological actions and can be used as good Bioanalytical tools. Therefore, an updated overview on current knowledge of green synthesis of nanoparticles (NPs), nanoformulations and surface modification using G. glabra is provided here in order to explore its therapeutic potential especially antifungal and antibacterial activities. In our lab, we have synthesized silver nanoparticles (Ag NPs) using leaves and rhizome parts of G. glabra.Humanity depends (directly or indirectly) exclusively on agriculture for their survival. Due to the exponential growth in population, it is imperative to use new scientific tools and technologies such as nanotechnology in agriculture. The objective of this review is to provide an overview of the use of nanomaterials (NMs) and nanoparticles (NPs) in form of nanofertilizers (NFs) to enhance plant nourishment, reflecting their potential benefits and possible uses, and also assessing their potential impact on ecosystem. NFs possess an alternative approach as compared to biofertilizers, biopesticides and organic fertilizers that started from green revolution. NFs affect crop's nutritional quality and stress tolerance in plants. There are both pons and cons of NPs and NMs when used in agriculture. These studies are necessary because NPs and NMs can be transferred to ecosystems by various pathways where they can cause toxicity to organisms, affecting the biodiversity and abundance of such ecosystems, and may ultimately even be transferred to consumers. The progress in the crop improvement processes such as implementation of nanodevices for genetic manipulation of plants depends on advanced techniques used in nanotechnology.Nano enabled plant protectant is an advancement approach to deal with the difficulties of dosedependent toxicity, solubility, degradation, leaching and health issues of conventional pesticides. The main idea behind incorporation of nanoformulation is their controlled delivery and release to prevent premature degradation of active ingredient under the influence of changing environment conditions. Nanocarriers (nanocapsules, nanospheres, micelles, nanogels, nanoemulsions, nanodispersion and inorganic material) alters the properties of active ingredients and provide controlled release kinetics with, better dissolvability, low dose, enhanced stability and long lasting pest-control efficiency. This review critically assesses the incredible potential of various nanocarriers, their methods of preparation and biological effectiveness. It additionally features the potential and issues with nanoformulations of botanical insecticides and essential oils. The study also accounts performances of nano-enabled products, their challenges with respect to field application and assessment of new environmental risks.A peculiar tower-like ZnO nanostructure was synthesized using an economical and facile hydrothermal method, with zinc acetate [ZAc, Zn(CH₃COO)₂ · 2H₂O] and hexamethylenetetramine (HMTA, C6H12N₄) as the source materials. The as-synthesized tower-like ZnO was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The characterization results indicated that the tower-like ZnO nanostructures are high-quality monocrystals. The as-synthesized ZnO nanostructures may have application in sensing area due to its high specific surface areas. The growth mechanism, as well as the optical properties of the as-synthesized tower-like ZnO nanostructures was also studied.High-resolution transmission electron microscopy (HRTEM), X-ray diffractometry (XRD), energy dispersive spectroscopy (EDS), and hardness testing are used to investigate the evolution of the long strip-shaped S' phase of spray-formed fine-grained Al-Cu-Mg alloy during rapid cold stamping deformation. Orforglipron chemical structure The elongated S' phase of the extruded Al-Cu-Mg alloy is subjected to twisting, brittle fracturing, redissolution, and necking during rapid cold stamping deformation. As a result, the morphology, size, distribution, and orientation relationship with the matrix of the long strip-shaped S' phase changed significantly. The regularly distributed long strip-shaped nanoscale precipitates evolved into irregularly distributed short rod-shaped S' phases and diffusely distributed granular reprecipitates. The twist and brittle fracture of the long strip-shaped S' phase significantly increased the contact surface between the precipitated phase and the aluminum matrix, improved the interfacial distortion energy of the precipitated phase and the aluminum matrix, and promoted the redissolution of the S' phase. The supersaturation state is reached, thus resulting in reprecipitation, which then lowered the matrix free energy. The hardness of the extruded Al-Cu-Mg alloy increased from 54.2 HB to 128.1 HB during the rapid cold stamping process.GOMoS₂ nanoparticle (NP) hybrid nanocomposite is prepared and studied structural, electronic and magnetic properties using X-ray diffraction, field emission scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy and superconducting quantum-interface-device measurements. MoS₂-NP exhibited diamagnetic characteristic but GOMoS₂-NP hybrid nanocomposite exhibited low temperature ferromagnetic characteristics. Field cooling and Zero field cooling characteristic exhibited divergence below ~280 K with increasing magnetic field. The saturation magnetic moment and coercivity of GOMoS₂-NP hybrid nanocomposite is higher than GO that could be useful for low temperature magneticities and energy storage device application.Coral reefs are cornerstone of global marine ecosystems, providing shelter for over one third of marine organisms. Currently, along with global warming and increased human activities, large-scale decline of coral reefs has become a severe ecosystem problem, and now quantitative detection of heat shock protein (HSP) gene by nanotechnology has become a research hotspot in this field. However, Acropora muricata is one of the most important dominant reef-building corals in Indo- Pacific region, encounter an urgent obstacle on the HSP detection research by nanoscience and nanotechnology for lack of sequence background. Here, we combined PacBio single molecular real-time (SMRT) and HiSeq X Ten sequencing technologies to perform full-length transcriptome sequencing of heat shock proteins in Acropora muricata, a reef-building coral dominant in many Indo-Pacific reefs, to annotate them. Thirteen functional heat shock proteins (HSPs) were identified using phylogenetic analysis, classified into three subgroups as HSP60, HSP70 and HSP90. HSPs are widely distributed in all animal phyla, having evolved from the last prokaryotic common ancestor. Additionally, phylogenetic and tertiary nanostructure analyses suggested that HSP70 is the most diverse HSP in A. muricata, with extensive sequence and structure differences indicating adaptations to warming water and suggesting its utility in studies of El Niño and other warming events. A greater understanding of the HSP gene family is likely to also be of value in studies of coral nanotechnological detection that can be used to protect reef ecosystems.Magnetic nanoparticles (MNPs) subjected to external alternating magnetic field can induce heat in MNPs due to hysteresis, which is usually employed for tumor hyperthermia. An effective hyperthermia treatment should selectively kill the tumor cells without damaging the ambient healthy tissue. Hence, it is important for hyperthermia to correctly control the alternating magnetic field-induced temperature of MNPs in the tumor. This work develops a thermal model to analyze various forms of temperature-rise with time in magnetic nanoparticles for tumor hyperthermia. Results show that there are horizontal, linear rise, square root, exponential decay and abrupt temperature-rise lines with time in MNPs. The horizontal, linear rise, and square root temperature lines with time are consistent with the available experimental data. It is worthily noted that the form of abrupt temperaturerise with time can result in harm to the normal cells or tissue. If the abrupt temperature-rise does not be controlled and predicted well.
