Based on previously published hydroponic plant, planktonic bacterial, and soil microbial community research, manufactured nanomaterial (MNM) environmental buildup could profoundly alter soil-based food crop quality and yield. However, thus far, no single study has at once examined the full implications, as no studies have involved growing plants to full maturity in MNM-contaminated field soil. ...

This study aimed to investigate the effect of nano-Ca fertilizer on nitrogen uptake, use efficiency and determine best calcium form dose for mango. A pot experiment was conducted using two year old mango seedlings (cv. Zebda). The pots were filled with sandy soil (8 kg per pot) one seedling transplanted into each pot. Four treatments including nano-Ca, convention Ca, application foliar have bee...

Nano-structured carbon nitride (CNx) films were synthesized by a reactive RFmagnetron sputtering system with a DC bias under various deposition conditions, and theirphysical and electrical properties were investigated with a view to using them for microhumidity sensors. The FTIR spectra of the deposited films showed a C=N stretching bandin the range of 1600~1700 ㎝⁻1, depending on the amount of ...

This research describes photo degradation of direct red 81(5-solamin) in the presence of zinc oxide nano-sized catalyst supported on granule glass under UV light irradiation. The effects of some parameters such as various pH and different atmosphere on photo degradation efficiency were studied. After various experiments it was revealed that among various atmospheres, at neutural medium, oxygen ...

The antioxidant activity of Aspergillus fumigatus was assayed by different procedures and correlated with its extracellular total phenolic contents. Different physio-chemical parameters were optimized to enhance the activity. The culture grown under stationary conditions for 10 days at 25°C at pH 7 gave the best antioxidant activity. Statistical approaches demonstrated sucrose and NaNO(3) to be...

The ability to measure extremely low thrust levels with unusual precision is becoming more critical as attempts are made to characterize the performance of emerging micropropulsion systems. Many new attitude control concepts for nanospacecraft involve the production of thrust below 1 μN. A simple, but uniquely successful thrust stand has been developed and used to measure thrust levels as low a...

The C-H activation of methane, ethane, and t-butane on inner and outer surfaces of nitrogen-doped carbon nanotube (NCNTs) are investigated using density functional theory. It includes NCNTs with different diameters, different N and O concentrations, and different types (armchair and zigzag). A universal structure-reactivity relationship is proposed to characterize the C-H activation occurring b...

The production system, especially fertilisation has an important effect on yield and quality of strawberries. In the present study, plants were fertilized with different doses nitrogen (0–100% recommended doses), calcium chelate, as well nano fertilizer Lithovit. Strawberry cultivar ‘Clery’ parameters (fruit color firmness) including nutritional indicators (total soluble solids, sugars, organic...

the current study presents synthesis and characterization of high impact polystyrene - tio2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. the solution-casting method was used for preparation of membranes. the nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...
