“…Our result was suggested that the increased zone of inhibition may stimulate by chitosan. The available essential oil compounds of Karimirad et al, 2019 , Topuz and Uyar, 2020 , Mishra et al, 2018 may play a anti-bacterial inhibition role against K. pneumoniae in this study. These compounds are major compounds in guva essential oils.…”

“…The prepared chitosan loaded essential oil morphological structure compared with chitosan alone was observed by SEM analysis using JSM-3456, JEOL, Japan at 15 kv ( Mishra et al, 2018 ). After complete preparation of essential oil within the chitosan, the samples were fixed in aluminum support with aid of carbon rib, being coated in liquid nitrogen contains gold metal surface to internal structure visualization.…”

“…Chemically, when the process of deacetylation process, the weaker hydrogen bonds of chitin are linked with N-acetyl glucosamine chins and formed as a chitosan, which possesses positively charged amino groups when it diluted in acidic solvent ( Mishra et al, 2018 , Rajivgandhi et al, 2019b ). Chitosan is formed with the help of negatively charged crosslinking agents in the natural polymers moieties of itself through intra- and intermolecular hydrogen bonds ( Karimirad et al, 2019 ).…”

The development of antibiotic resistant in K. pneumoniae is an emerging thread worldwide due to the poor antimicrobial drugs. To overcome this issue, researchers are focused on plant material and their essential oils to fight against multi drug resistant bacteria. In this context, the current study was concentrated in medicinal plant of guva leaves and their essential oils to combat multi drug resistant bacterial infections. The essential oils were successfully screened and confirmed by HRLC-MS analysis. The anti-bacterial ability of the compounds were loaded into the chitosan nanoparticles and proved by FT-IR analysis. In addition, the chitosan loaded essential oils morphology was compared with chitosan alone in SEM analysis and suggested that the material was loaded successfully. Further, the anti-bacterial ability of the chitosan loaded essential oils were primarily confirmed by agar well diffusion method. At the 100 µg/mL of lowest concentration of chitosan loaded essential oils, the multi-drug resistant K. pneumoniae was inhibited with 96% and confirmed by minimum inhibition concentration experiment. Hence, all the experiments were proved that the essential oils were successfully loaded into the chitosan nanoparticles, and it has more anti-bacterial activity against multi-drug resistant K. pneumoniae.

“…34,36,[40][41][42][43][44][45] Current study proposed the use of Cymbopogon citratus (commonly known as lemongrass) leaf extract as reducing of metal precursors and capping agent, due to the high content of phytochemicals such as neral, citral, geranial, pinito, allantoin flavonoids, hydrocarbons, waxy esters, sterol esters, ketones, aldehydes, terpenoids, phenols, fatty alcohols, fatty acids, among others. [46][47][48][49][50][51][52] This plant is widely available in tropical and semitropical environment zones throughout Asia, Africa, and South America. 53,54 Therefore, lemongrass leaves were proposed to be part of the raw material in the synthesis of TiO 2 and ZnO nanoparticles since they are easily found in the Department of Bolivar (Cartagena, Colombia) and are no part of the food chain.…”

Recently, an increase in the production of intelligent nanomaterials has been reported for the application of solid surface coating. These nanomaterials provide a wide number of functionalities such as anticorrosive, antibacterial, and self-cleaning properties. Hence, titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles were synthesized using a green chemistry approach. These nanoparticles were fully characterized by scanning electron microscopy, energy-dispersive X-ray, high-resolution transmission electron microscopy, X-ray diffraction, ultraviolet (UV)–visible spectroscopy, Brunauer–Emmett–Teller test, and nitrogen adsorption–desorption isotherm. Then, a commercial enamel-type paint was modified by using different concentrations (2, 3.5, and 5 w/v%) of nanoparticles. These nanofilled paints were then brushed onto the surface of different types of materials such as carbon steel sheets, wood sheets, and aluminum disks. Anticorrosive, self-cleaning, and antibacterial properties of the nanofilled paints were evaluated, with the aim to determine the capability for this application. According to the characterization results, TiO2 and ZnO nanoparticles exhibited similar physicochemical properties compared to those synthesized using traditional methods. The anticorrosion results revealed that nanofilled paints provide a barrier using low concentrations of nanoparticles, due to the decrease of agglomerates on the surface avoiding the presence of high porosity. In the case of self-cleaning, a proposed mechanism of degradation demonstrated that the presence of both nanoparticles in the paint provided high degradation of methylene blue due to the high surface area offered by the nanoparticles. On the other hand, antibacterial activity under UV light was observed only for ZnO nanoparticles, which may be related to the diffusion of nanoparticles into the cell membrane of the bacteria, affecting the normal function. These results showed to be promising for the modification of paints with TiO2 and ZnO nanoparticles, and the application on solid surfaces for the construction, and even in textile fields.

Olfactory sensing and perception play an important role in people's daily lives and greatly affects senses, emotions, and behavior. In particular, the development of the controlled release of aroma enhances human's well‐being and strengthens interactions with surroundings through olfactory display, especial when combined with visual and audial cues. Here, Ti3C2 MXene plays a dual‐function role as the adsorption site of aroma molecules and the heating source for the controlled release of aroma molecules. Due to abundant termination groups on the surface and the metallic nature, Ti3C2 MXene provides abundant active sites for the interaction with aroma molecules; simultaneously, MXene can be electrically heated to thermally desorb the aroma molecules from the interaction sites. This approach eliminates the interface incompatibility issues between the heating source and the molecular encapsulation layer in conventional olfactory display system. This work presents the controlled release of the aroma molecule phenethyl alcohol (PA) using Ti3C2 MXene paper. Ti3C2 MXene paper serves as the adsorption material and a heating source that achieves 100 °C within 1 s. The relative amount of PA released reaches nearly 100% after 1 min of heating.
