News On Technology For Future

1. Stainless Steel is an alloy of iron and chromium with minimum 10.5 percent. 2. Chromium produces a thin layer of oxide on the surface of steel called as "passive layer". This prevents corrosion. 3. for other useful properties it also contains carbon, silicon, manganese, nikel, molybdenum. 4. stainless steel was discovered in 1913 sheffield metallurgist Harry Brearley. 5. Types of corrosion in stainless steel: Pitting Corrosion, Crevice Corrosion, General Corrosion, Stress Corrosion Cracking (SCC), Intergranular Corrosion, Galvanic Corrosion pitting Corrosion due to chlorine ion like in salt and bleach. to avoid it have to use high resistance steel to corrosion. Crevice corrosion is due to lack of oxygen on the passive layer. For this use flexible sealant or high corrosion resistant grade. General Corrosion due to certain concentrated hydrochloric Acid, Sulphuric Acid. Stress Corrosion Cracking (SCC): This corrosion normally happens in hot water tank and swimming...

BY CONVERTING HEAT TO FOCUSED BEAMS OF LIGHT, A NEW SOLAR DEVICE COULD CREATE CHEAP AND CONTINUOUS POWER. AVAILABILITY: 10 TO 15 YEARS Solar Panels cover a growing number of rooftops, but even decades after they were first developed, the slabs of silicon remain bulk, expensive, and inefficient. Fundamental limitations prevent these these conventional photovoltaics from absorbing more than a fraction of the energy in sunlight. A team of scientists has built a different sort of solar energy device that uses inventive engineering and advances in material science to capture far more of the sun's energy. The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use. While various researchers have been working for years on so-called solar thermophotovoltaics, the device is the first one to absorb more energy than its photovoltaic cell alone, demonstrating that the approach could dramatically increas...

My 3rd post Dated: 4/1/18 When you think about the future of robotics, your initial thoughts are probably far from the kitchen, and perhaps further away from preparing fresh meals. Yet robots are entering every corner of our lives, and are emerging as growing part of the future of food. A need for agricultural robots Around the globe, healthier foods like fresh fruits and vegetables are becoming more expensive while processed foods linked to increased health problems are becoming cheaper and more easily accessed. A 2015 study by the overseas Development Institute, an independent think tank focused on humanitarian issues and international development, found that in the emerging economics of Brazil, China, Korea, and Mexico, the cost of fresh fruits and vegetables has risen by up to 19% from 1990 to 2012. In addition, the cost of processed food like ready-made meals has dropped by up to 20%. So, where do robots fit into all of this? Clearly, the problem of access to fresh, u...

my 2nd post dated: 3/1/18 Scientists are developing a novel technology that may economically convert fossil fuels and biomass into useful products, including electricity, without emitting carbon dioxide into the atmosphere. Engineers at the Ohio State University in the US devised a process that transforms shale gas into products such as methanol and gasoline- all while consuming carbon dioxide. Te process can also be applied to coal and biomass to produce useful products, researchers wrote in the journal Energy & Environmental Science. Under certain conditions, the technology consumes all the carbon dioxide it produces plus additional carbon dioxide from an outside source, they said. The researchers have also found a way to greatly extend the lifetime of the particles that enable the chemical reaction to transform coal or other fuels to electricity and useful products over a length of time that is useful for commercial operation. The same team has discovered and patent...

dated: 2/1/18 , 22:06 Both virtual reality and augmented reality have been around more than a couple of years at this point, but the technology is largely still its infancy. With a bulky headset required to experience the technology in the majority of cases, it feels like an older piece of equipment despite utilizing the latest advancements in technology to deliver a unique and entertaining experience. The bulky equipment required for virtual and augmented reality could change in the near future, however, with the advent of a new metalens technology. A metalens focusing on the entire spectrum of light- including white light-was a challenge to develop, because each wavelength moves through the lens at different speeds. The differing speeds mean that the light will reach the lens at different points, which is a problem when trying to develop a metalens for AR and VR. Traditional VR and AR devices use, "multiple curved lenses of different thickness and materials to correct th...
