Solid propulsion technology nanoparticulate materials, such as hematite and maghemite, exhibit high performance on thermal decomposition of ammonium perchlorate. The enhanced catalytic effect of metallic iron oxide nanoparticles is attributed to their particle size, more active sites and high surface area, which promotes more gas adsorption during thermal oxidation reactions. Nowadays, metallic iron nanoparticles can be synthesized via numerous methods, such as co-precipitation, sol-gel, microemulsion, or thermal decomposition. Although there are data on these synthetic methods in the literature, there is a lack of details related to nanoparticulate oxides and to their characterization techniques. In this context, this short review based on scientific papers, including data from the last two decades, presents methods for obtaining nanoparticulate iron oxides as well as the main aspects of the different characterization techniques and also about the decomposition aspects of these nanomaterials. Morphologies and structures of iron oxides can be characterized through transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, and Fourier transform infrared spectroscopy. As for textural properties, they are usually determined by physical adsorption techniques.

The timing of floral transduction has a direct impact on the reproductive success and is influenced by physiological signals mediated endogenously as well as exogenously. Flowering is the first step of sexual reproduction, so it is important to find out the factors that regulate the signals during the transition phase. The instance of floral evocation has started an unstoppable cascade on the path of reproductive success which can be regulated by sensible signals. The receptivity and inductive signals essential for flowering vary in plant species, and, create a line of differentiation, although basic calls are conserved. The transition progression in plants for blooming under diverse environmental facilities provokes the identity to force the change from vegetative to reproductive phase. Winter memory, light flakes, endogenous hormonal cycling, nutrient status, and contiguous environments are all the factors which set the center stage for flowering. Flowering is well-established by approaches which work in a combinatorial manner and, ensure a cushion for the plant to create a miniature for future. In this review, we provide a detailed outlook on fundamental cues instigating blooming: where, how and when the flowering signals are created.

This climbing deciduous shrub widely reported in China, Bangladesh and Srilanka. The plant is rich in many phytoconstituents that are useful in drug designing. It is highly used against cancer, tumour suppression, and act as an anti-allergic compound. It is commonly known as gudhuchi, belongs to the family Menispermeaceae. Tinospora is most valuable herb known for its medicinal properties from Vedic periods and cures various diseases such as malaria, asthma and urinary disorders. The genus Tinospora consists of many classes of chemicals such as alkaloids, diterpenoids lactones, steroids, aliphatic compounds and polysaccharides. It is the best remedy for both children as well as adults against respiratory tract diseases. The plant shows various antioxidant, anti-hyperglycemic, anti-neoplastic and hepatoprotective properties. In this review article medicinal property, chemical constituents and full description have been explored.

Nanotechnology driven innovations have given a hope to the patients as well as physicians in solving the complex medical problems. Nanoparticles with a size ranging from 0.2 to 100 nm are associated with an increased surface to volume ratio. Moreover, the physico-chemical and biological properties of nanoparticles can be modified depending on the applications. Different nanoparticles have been documented with a wide range of applications in various fields of medicine and biology including cancer therapy, drug delivery, tissue engineering, regenerative medicine, biomolecules detection, and also as antimicrobial agents. However, the development of stable and effective nanoparticles requires a profound knowledge on both physico-chemical features of nanomaterials and their intended applications. Further, the health risks associated with the use of engineered nanoparticles needs a serious attention.
