Knowledge is the weapon

Prime Minister Narendra Modi’s led 'Swachh Bharat Abhiyan' which has started on 2nd Oct on the auspicious occasion of birth anniversary of our Rastrapita Mahatma Gandhi, has been proved a great success as large number of people has participated in this grand event. It is the biggest ever cleanliness and sanitation drive in the country. The mega event like this has not been witnessed by me in the past. This is great initiative by our beloved Prime Minister to make us realize our duty towards our country. He has also physically participated in the cleanliness drive to motivate us. A 'clean India' by 2019 when the nation will mark 150th birth anniversary of Mahatma Gandhi is the vision driving the mission. Generally 2nd Oct is regarded as a National Holiday and all offices, school, colleges remain closed on that day, but the PM has made the day useful by announcing the drive to clean their office, school, college premises, toilets and surrounding areas. In our offic

In our previous post, we had talked about flexible batteries which will enable the future devices to be made flexible. In this post we will talk about development in the field of real flexible display. Flexible Display A flexible display is a display which is flexible in nature; differentiable from the more prevalent traditional flat screen displays used in most electronics devices this is not just bendable or curved display which is now a day available in the market. We are talking about the display which can be rolled in your hand or can be wrapped in your hand. Let’s talk about the technology behind on which scientist are working on. Electrophoretic, or, electronic ink E Ink is the creator of electrophoretic, or, electronic ink — the optical component of a film used in Electronic Paper Displays (EPD). These are designed to mimic the appearance of ordinary ink on paper. Characteristics of E-Ink Bistable E Ink's technology is commonly referred to as "

What is flexible batteries.....  Now a days with advancement in technology, there has developed may gadgets which are flexible and which can take user defined shape. These gadgets cannot run on its own as it require power source. This requirement of power source has made the gadgets limited in flexibility. It has made it necessary to develop a process to make batteries flexible too. Researches are being carried out to make the primary(non-rechargeable) as well as secondary(rechargeable) batteries flexible. Basic Design In general, a battery is made of one or several galvanic cells, where each cell consists of cathode, anode, separator, and in many cases current collectors. In flexible batteries all these components need to be flexible.

The difference between NPT, BSPP and BSPT seals As I told in my previous post, Now follow a bit of information about different pipe threading and their compatible sealing. NPT Connections NPT (National Pipe Thread) seals are the most popular type of seal for pressure calibration systems in the U.S. and Canada. NPT male adapters have a taper thread that wedges into the female NPT adapter. They seal due to the “out of roundness principle” which means that the male stretches the female fitting until there is so much force that the connection can hold pressure. One of the challenges with this design is that if you connect stainless steel to stainless steel then over-tightening or poor lubrication can cause damage to the threads. Thread sealant is needed to seal but only 2 turns of thread sealant is required. Any more than that and the seal can leak around the thread sealant. BSPT Connections BSPT (British Standard Pipe Taper) is similar to NPT except for one important differenc
