Nanorobotics

-

 Nanorobotics is an emerging field of technology that involves creating tiny surgical robots whose components are roughly the size of a nanometre (equivalent to one-billionth of a metre or one-millionth the length of an ant).


With their microscopic size, these burgeoning technologies will enable scientists to manipulate biological matter at an atomic or molecular level — with seismic implications for our ability to effectively fight diseases.


In surgery, medical nanobots will be introduced into the body in a minimally invasive way via the vascular system or other cavities. Programmed or directed by a human surgeon, they would perform crucial functions such as searching for pathogens. Because nanobots are capable of recording vital signs such as temperature and blood pressure, it’s thought this technique will enable doctors to diagnose, test and monitor microorganisms, tissues and cells in the bloodstream.


Nanotechnological innovation in healthcare recently had a huge breakthrough: in February 2018, researchers were able to shrink tumours in mice by using cancer-hunting nanobots to cut off the blood supply. For cancer patients, this development offers a glimmer of hope. If the technique gains approval for future use on humans, it could offer a less harmful and more successful alternative to chemotherapy.

Alternating Current

  What Is Alternating Current? An  alternating current  can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC, which always flows in a single direction as shown below From the graph, we can see that the charged particles in AC tend to start moving from zero. It increases to a maximum and then decreases back to zero completing one positive cycle. The particles then reverse their direction and reach the maximum in the opposite direction after which AC again returns to the original value completing a negative cycle. The same cycle is repeated again and again. Alternating currents are also accompanied usually by alternating voltages. Besides, alternating current is also easily transformed from a higher voltage level to a lower voltage level.

SOLAR TRANSFORMERS

  The transformers required for wind power and solar DPV require special design features to meet the challenging operating conditions. The industry today has developed different types of transformers for the application. The last few decades have seen very rapid development of renewable energy, especially, distributed photovoltaic (DPV) and wind power. It is estimated that at least 40 per cent of electricity generation by year 2040 would be from renewable energy sources and this would give appreciable reduction of the present level of carbon dioxide emissions of about 10 billion tons per year. The transformer industry is rising to this challenge and has developed special transformers for the DPV generation and wind generation. Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, su
