“…The smaller size and high surface-to-volume ratio of nanomaterials give them distinct and advantageous properties in different scientific fields compared to their bulk analog ( Yang et al, 2022 ). The NM has unique physiochemical properties and flexible scaffolds, making them functional with biomolecules and unique compared to other materials ( Muthukumaran et al, 2022 ). Furthermore, it has been demonstrated that some NMs, such as magnetic ( Armenia et al, 2022 ), gold ( Jiang et al, 2017 ), polymeric ( Kamaly et al, 2016 ), or hybrid NMs ( Ferreira Soares et al, 2020 ), may react to external stimuli, leading to a spatiotemporally regulated release of macromolecules.…”

Synergistic impact of nanomaterials and plant probiotics in agriculture: A tale of two-way strategy for long-term sustainability

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner in order to fulfill the food demands of an ever-increasing global population. However, intensive agricultural practices, rampant use of agrochemicals, and other environmental factors result in soil fertility degradation, environmental pollution, disruption of soil biodiversity, pest resistance, and a decline in crop yields. Thus, experts are shifting their focus to other eco-friendly and safer methods of fertilization in order to ensure agricultural sustainability. Indeed, the importance of plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, and their usage as biofertilizers is being actively promoted as a means of mitigating the harmful effects of agrochemicals. As bio-elicitors, PPs promote plant growth and colonize soil or plant tissues when administered in soil, seeds, or plant surface and are used as an alternative means to avoid heavy use of agrochemicals. In the past few years, the use of nanotechnology has also brought a revolution in agriculture due to the application of various nanomaterials (NMs) or nano-based fertilizers to increase crop productivity. Given the beneficial properties of PPs and NMs, these two can be used in tandem to maximize benefits. However, the use of combinations of NMs and PPs, or their synergistic use, is in its infancy but has exhibited better crop-modulating effects in terms of improvement in crop productivity, mitigation of environmental stress (drought, salinity, etc.), restoration of soil fertility, and strengthening of the bioeconomy. In addition, a proper assessment of nanomaterials is necessary before their application, and a safer dose of NMs should be applicable without showing any toxic impact on the environment and soil microbial communities. The combo of NMs and PPs can also be encapsulated within a suitable carrier, and this method aids in the controlled and targeted delivery of entrapped components and also increases the shelf life of PPs. However, this review highlights the functional annotation of the combined impact of NMs and PPs on sustainable agricultural production in an eco-friendly manner.

“…Upon separation, the resulting cellulose is further treated for the production of paper. The Kraft pulping process is challenged with complete or partial plugging of the filter cake and/or of the filter medium [54,55]. This blockage changes lignin solubility while it induces a high pH level and this consequently brings about restructuring of the lignin particle.…”

A Review on Lignin-Based Carbon Fibres for Carbon Footprint Reduction

Carbon fibers (CFs) are made mostly from a non-environmentally friendly polyacrylonitrile (PAN) and little from rayon. PAN-based CFs, require huge amount of energy for its production aside its contributions to the global CO2 emission. Therefore, there is recourse to a more environmentally friendly sources of CFs biomass. Recently lignin has been recognized as a potential renewable raw material for carbon fibers to replace PAN-based. The magnitude and quality of CO2 emission of lignin-based CFs are dependent on the processing route. On this premise; this review examines the various lignin-based CFs processing route adopted by researcher in the recent past to establish the most viable route with minimum carbon footprint emission. Outcome of the review shows that the major advantages of aromatic polymer (AP) generated precursor over PAN is the presence of higher quantity of guaiacyl units and oxygen content which makes the stabilization phase efficient and faster requiring less energy. Though there are several methods and options for the various stages of conversion of lignocellulosic biomass into CFs as highlighted in the study, establishing an optimum processing route will be a trade-off amongst various issues of concern; carcinogenic risk, carbon footprint emission, CFs Yield and mechanical strength of the CFs. Inferences from the study shows that the L-CF significantly produced reduced climatic impact in terms of CO2 emission.

“…Numerous attempts have been made to enhance the biopolymer's characteristics using the idea of nanotechnology, which decreases the drawbacks of packaging materials developed of biopolymers. [9][10][11] The fabrication of nanoscale reinforcement into the polymer significantly improves the material of the biopolymers. Incorporating nanofillers into biopolymers, such as zinc oxide (ZnO), titanium dioxide (TiO 2 ), clay, silicate, silver nanoparticles (AgNPs), nano-cellulose, and so on, not only increases the barrier and mechanical properties but also speeds up other processes like oxygen scavenging, biosensing, and antimicrobial activity.…”

Packaging is a growing field of interest, and the use of nanotechnology is accelerating its expansion. The study reports the fabrication of poly(vinyl alcohol) (PVA) blended sodium alginate (SA) and incorporated with different ratios of histidine‐capped silver (H‐AgNPs) nanoparticle films. Fabrication of PVA/SA/H‐AgNPs films was confirmed with the surface plasmon resonance (SPR) band denoted AgNPs presence between 400 and 420 nm measured by UV–Vis absorption spectroscopy. The characteristics of the polymeric biocomposite films were significantly altered by different ratios of AgNPs. The interaction of PVA/SA and PVA/SA with AgNPs was analyzed by using FT‐IR analysis. The degree of crystallinity was increased upon increasing the concentration of H‐AgNPs as confirmed by XRD measurements. The homogeneity of dispersion and surface morphology of samples were studied by FESEM. The addition of H‐AgNPs in the polymeric film increased the surface roughness of the polymeric film confirmed by AFM analysis. The contact angle of the PVA/SA blend matrix was observed to be 46.97°, and with the incorporation of AgNPs ranging from 3%, 5%, and 7% to the blend matrix, the contact angle of the nanocomposite films in increasing hydrophobic order was 60.53°, 83.57°, and 96.20°, respectively. The incorporation of AgNPs also demonstrates that the PVA/SA blend matrix has desirable thermal stability. The improved qualities were due to H bonding between PVA, SA, and H‐AgNPs, in which molecules contact strongly with one another. Furthermore, the PVA/SA/H‐AgNPs showed significant antibacterial activity against both Gram‐positive (G+) strains (Staphylococcus aureus) and Gram‐negative (G−) strains (Escherichia coli) bacterial infections. The findings of this research indicate that the PVA/SA/H‐AgNPs fabricated composite films considerable for applications in food packaging.
