“…19 Plant cells accumulate free radicals owing to reduced antioxidant capacity during adverse conditions, leading to the oxidative damage of cellular macromolecules and membranes. 30,31 Furthermore, autotoxic metabolites produced by the stressed plants accelerate free radical-induced membrane peroxidation and breakdown, thereby providing nutrients to the pathogens and enhancing their ability to invade plant roots. In fact, the activity of the antioxidant enzymes POD and CAT are reliable indicators of disease resistance in plants.…”

We intensively studied faba bean (Vicia faba L.) and wheat (Triticum aestivum L.) intercropping and found that this type of intercropping can effectively control the occurrence of faba bean wilt under field conditions. We conducted hydroponic experiments to explore the role of plant extracts in the process of soil-borne diseases and the mechanism of disease control of faba bean and wheat intercropping. In this experiment, three concentration gradients of faba bean and wheat stem, leaf, and root extracts were added to study the effects of faba bean and wheat extracts on faba bean growth, the physiological resistance of roots, and the growth of Fusarium oxysporum f. sp. fabae (FOF). Faba bean extracts significantly inhibited the growth of faba bean seedlings and the activity of root defense enzymes and significantly stimulated the growth of FOF at high concentrations. Compared with the treatment with faba bean extracts, wheat extracts significantly enhanced the growth of faba bean seedlings, increased the activity of defense enzymes, and inhibited the growth of FOF. Based on these results, we believe that wheat extracts can effectively alleviate the autotoxicity of faba beans and also control the occurrence of faba bean wilt in the field. This provides a theoretical basis for practical intercropping to reduce the damage caused by faba bean wilt.

“…Surfactants are one of the most important components in the ME preparations because they create a mechanical film and an electrical film (if charged) between the internal phase droplets (oil phase) and also reduce the surface tension [32,33]. Co-surfactants facilitate surfactants in creating a stronger barrier, decrease the rigidity of the surfactant interfacial film by reducing the bending stress of the interface, and give more flexibility to the interfacial film [34,35].…”

The objectives of this study were to develop an optimized formulation for an Andrographis paniculata extract (AGPE)-loaded self-microemulsifying drug delivery system (SMEDDS) using an experimental design and evaluate the characteristics of the developed SMEDDS. The solubility of andrographolide (AGP) in various solvents was investigated. The pseudo-ternary phase was constructed to provide an optimal range for each component to form microemulsions (MEs). The formulation was optimized using an I-optimal design mixture type, where the physical stability, droplet size, polydispersity index, and zeta potential were examined. Soft capsules of the optimized AGPE-loaded SMEDDS were manufactured. The dissolution and ex vivo membrane permeation were studied. Oleic acid, Tween® 80, and PEG 400 were the best solubilizers for AGP. The promising surfactant to co-surfactant ratio to generate ME was 3:1. The optimized SMEDDS contained 68.998% Tween® 80, with 13.257% oleic acid and 17.745% PEG 400. The assayed content of AGP, uniformity of dosage unit, and stability complied with the expected specifications. The dissolution and membrane permeability of AGPE-loaded SMEDDS was significantly improved from the A. paniculata extract (p < 0.05). All in all, the developed optimized AGPE-loaded SMEDDS was proven to contain optimal composition and AGP content where a stable ME could spontaneously be formed with enhanced delivery efficacy.

“…99 The effect of the length of cosurfactant chain length on the growth kinetics (shape and size) of the MEDs formed as well as the shape and size of copper oxalate (CuO x ) nanostructures was investigated using SAXS. 100 Two cosurfactants, 1-butanol (4 C) and 1-octanol (8 C), were used in the CTAB/cosurfactant/isooctane/water MED system. It may be mentioned here that the use of 1-butanol yields CuO x nanorods, while 1octanol yields CuO x nanocubes.…”

“…In the first stage (stage 1, Scheme 2a), the polymer induced the formation of shuttle-like nanocrystals that were oriented along the c-axis. These shuttle-like nanocrystals subsequently attached with one another in a directed manner, resulting in the formation of [100]-oriented shafts that had many parallel needle-like structures oriented along the [001] direction, i.e., perpendicular to the [100]-oriented shaft. Stage 2 was surfactant-controlled (Scheme 2b) as, at this stage, the polymer had been substantially depleted from the reaction mixture.…”

Mechanistic Investigations of Growth of Anisotropic Nanostructures in Reverse Micelles

Tailoring the characteristics of anisotropic nanostructures like size, morphology, aspect ratio, and size dispersity is of extreme importance due to the unique and tunable properties including catalytic, optical, photocatalytic, magnetic, photochemical, electrochemical, photoelectrochemical, and several other physical properties. The reverse microemulsion (RM) method offers a useful soft-template and low-temperature procedure that, by variation of experimental conditions and nature of reagents, has proved to be extremely versatile in synthesis of nanostructures with tailored properties. Although many reports of synthesis of nanostructures by the RM method exist in the literature, most of the research studies carried out still follow the "hit and trial" method where the synthesis conditions, reagents, and other factors are varied and the resulting characteristics of the obtained nanostructures are justified on the basis of existing physical chemistry principles. Mechanistic investigations are scarce to generate a set of empirical rules that would aid in preplanning the RM-based synthesis of nanostructures with desired characteristics as well as make the process viable on an industrial scale. A consolidation of such research data available in the literature is essential for providing future directions in the field. In this perspective, we analyze the literature reports that have investigated the mechanistic aspects of growth of anisotropic nanostructures using the RM method and distil the essence of the present understanding at the nanoscale timescale using techniques like FCS and ultrafast spectroscopy in addition to routine techniques like DLS, fluorescence, TEM, etc.
