The present experiment was conducted during rabi season, 2014-15 at students Instructional Farm (SIF), C.S. Azad University of Agriculture and Technology, Kanpur with an object to find out suitable and economical combination of rabi intercrops with citronella (Cymbopogon winterianus L.). The experiment was laid out in completely randomize design with 09 treatment of cropping systems with different combination (sole citronella, sole Mustard, citronella+Mustard (100%RDF), citronella + Mustard (75%RDF), citronella+Mustard (50%RDF) were replicated. Soil treatments with 100%RDF treated as control.The soil of experimental field was slightly alkaline with 8.09pH and 0.21 EC. The soil is low in organic carbon and low in available nitrogen (260kg/ha), medium in available phosphorus (17.55kg/ha) and medium in potash (175kg/ha). The citronella crop (cv. Bio-13) was transplanted in 30 July, 2010 at 60x60cm. The rabi crop Mustard (cv. Urvasi) was sown 19 October 2014 14 at 40x20cm. The intercrops during rabi season were also sown along with citronella as per treatment to maintain the row ratio of 2:2. The rabi crop Mustard was harvested on 24 March 2015 respectively.The citronella herbs were harvested during the experimental period on 17 December 2014. After harvesting of citronella herbs, distillation was done for oil extraction.Organic matter and available nitrogen is highest in mustard sole and citronella: mustard intercropping with all three fertility levels i.e. 100%, 75% and 50%RDF, respectively. The available phosphorus (P 2 O 5 ) was highest in citronella: mustard intercropping system with 100% and 75%RDF fertility level, respectively. The available of potash was decreased year by year but the highest potash was found in citronella sole. PH value in sole citronella and intercropping of citronella with mustard different fertility levels decreases yearly.Cultivation of citronella sole crop was superior over sole mustard cropping system. In intercropping system the highest citronella equivalent oil yield was found in citronella: Mustard 100% RDF followed by 75%RDF treatment, respectively. The highest net return was found in sole citronella system because B:C ratio is 4.56 followed by C: M with 100% RDF intercrop system with B:C ratio.

“…Nanotechnology has contributed to finding solutions to bacteria elimination problems, e.g., carbon-based materials such as graphene oxide (GO), reduced graphene oxide (r-GO), carbon dots (CDs), and carbon nanotubes (CNTs) (5). Also, metal nanoparticles (NPs) such as AgNPs, AuNPs, PtNPs, etc., (8) and metal oxide NPs like magnetite (Fe3O4) and maghemite (γ-Fe2O3) (9) have been employed to combat this problem due to their intrinsic antibacterial activity and, according to their nature, they can inhibit gram-positive and gram-negative bacteria by different mechanisms (1,(10)(11)(12). In several cases, the antimicrobial activity of the cited nanomaterials can be enhanced with functionalizing agents (antibiotics, polymers, organic molecules, etc.)…”

Magnetic nanoparticles based on iron oxides (MNPs-Fe) with magnetite or maghemite phases have been widely employed in bio-applications. Thus, they have been used as contrast agents in magnetic resonance imaging (MRI) and oncological treatments through different therapies. Besides, due to the vast health problem of multidrug-resistant bacterial infections, several studies have proposed MNPs-Fe as photothermal agents (PTAs) within antibacterial photothermal therapy (PTT). This work presents a quick and easy green synthesis (GS) to obtain MNPs-Fe using orange peel extract from orange waste from local commerce, which presents an environmentally friendly approach compared to traditional methods such as coprecipitation. The GS can be irradiated with microwaves to reduce the synthesis time drastically. We evaluated the weight yield of the GS and the physical-chemical and magnetic features of the synthesized MNPs-Fe. Besides their cytotoxicity in animal cell line ATCC RAW 264.7, their antibacterial activity against Staphylococcus Aureus (S. Aureus) and Escherichia Coli (E. Coli) was assessed. We found that the MNPs-Fe synthesized using the GS, with 50% v/v of NH4OH and 50% v/v of orange peel extract (50GS-MNPs-Fe) had an excellent weight yield, negligible cytotoxicity for concentrations of MNPs-Fe below 250 µg·mL-1 in 24 hours, and 8 days. In the MNPs-Fe surface, we identified a coating of organic molecules (~ 25 nm) such as terpenes, aldehydes, etc. MNPs-Fe inhibited S. Aureus and 2.54 log10 (CFU) of E. Coli under red LED light irradiation (630 nm, 65.5 mW·cm-2, 30 min). Likewise, they exhibited a superparamagnetic (SPM) behavior for temperatures above 60 K, with a size of 49.3±9.6 nm and saturation magnetization (Ms) of 72.83 and 44.16 emu·g-1 at 60 and 300 K, respectively. Therefore, 50GS-MNPs-Fe are excellent candidates as broad-spectrum PTAs in antibacterial PTT, magnetic hyperthermia (MH), or MRI.
