The rise of nanotechnology has brought to the world a new potential and the use of different nanomaterials has revolutionized both the industrial and biomedical worlds with the broader perspective of what humanity can achieve through material manipulation at the nanoscale.  Nanoscale particles possess distinct characteristics which  advances in exploring and exploiting the uses of nanostructured materials.   Due to the high surface to volume ratio and high reactivity there is a great potential for metal and metaloxide nanostructures. Synthesis of nanoparticles by physical and chemical methods are costly and toxic to the environment. Use of biosynthesis provides advancement over physical and chemical methods and may lead to the development of clean, non-toxic and environmental acceptable procedures which involves organisms ranging from bacteria to fungi and also plants.  Green synthesis of metal nanoparticles is an expanding area of research  and in the current study, Murraya koenigii i.e., Curry leaf powder was used for the green method  by which  manganese oxide nanoparticle synthesis was developed. Murraya Koenigii which belongs to Rutaceae family has  found to be potent antioxidant due to high concentrations of carbazoles, a water soluble heterocyclic compound  and also responsible for the reduction  of metal ions.   The present study focus on the development manganese oxide nanoparticles from the leaf extract of murraya koenigii where potassium permanganate act as  precursor. Crystal phase identification of manganese oxide  nanoparticles was studied by X-ray diffraction analysis and  optical characterisation was carried out using Uv-Vis spectrophotometer.

At present, in the whole world from developed countries to third-world, digitization has taken place in society and economy with great intensity and also being adapted by a common person as his/her normal daily routine. Due to this huge amount of data is being processed and stored in data centers. Based on earlier studies, it has been observed that, Due to the overload of data & traffic, data centers are consuming more energy than any other setup. Energy consumption of hyperscale & mid level data centers increasing continuously from the very beginning of their setup. As the demand of energy is growing, so the need of production and expense on energy is also growing in energy demand in future (at-least one decade). In this paper one of the topics specially related to the improvement of energy efficiency through IT software has been taken. And a method has to be established whereby all the data centers with different geographical locations can have fewer loads on power sources and they can take advantage of low cost energy and hence will be able to operate even less.

Applied to almost every branch of mathematics. The interesting part in Vedic mathematics is, you can mostly check your calculation and know whether you are right or wrong in few seconds and that makes it more enjoyable. Here, discuss some applications of Vedic mathematics in one of its field i.e. Algebra and see how it saves a lot of time & efforts in solving the problems.

In order to meet safety standards,  several systems have been studied and developed. The brake systems are one of the most critical systems in the vehicle, other than having an air bag, good suspension systems, good handling and stable cornering. Passengers may be placed in a dangerous position without a braking mechanism in a car. It is therefore important that all vehicles have a proper braking system. Braking is a mechanism that transforms the vehicle's kinetic energy into mechanical energy. The disc brake is a system which is used to de-accelerate or stop wheel rotation. The wheel is attached to a brake disc or rotor, typically made of cast iron or a ceramic composite. By acting mechanically, hydraulically, pneumatically or electromagnetically on both sides of the disc, the friction material of  the brake pad mounted on a system called a brake calliper is forced to stop the wheels. For the investigation of how disc brake functions more effectively, it is important to understand action force and friction force on the disc brake with new material, which can help minimise heat generation and provide better tribological performance.
