Work published in the International Journal of Business Innovation and Research, reveals how designers benefit from the sharing of 3D designs. There is huge potential for bespoke, one-off products, replacement parts made on-demand by an agency or anyone with a 3D printer of their own, and, of course, there is a whole new realm of artistic endeavour available through this technology. So much so that it is often referred to as additive manufacturing. It has been something of a long-term technological revolution changing the way low-demand objects are designed and produced. It has become, if not commonplace, then more well-known and utilised in wide-ranging industries, it is. Three-dimensional printing, 3D printing, has developed steadily over the last three decades or so.
(2020) 'Study on production, characterisation and utilisation of neem biodiesel as green fuel for compression ignition engine', Int. Neem biodiesel may thus represent a potentially sustainable fuel. Specifically, analysis of carbon dioxide generated shows that the use of the 20% blended neem biodiesel, led to savings in carbon dioxide emissions of more than 0.14 kilograms per kilowatt hour of power generated. These are two important factors in opting for biodiesel rather than petrochemical diesel. However, it reduced smoke opacity and also led to savings in carbon dioxide emissions. The blended bio-product had little impact on brake specific fuel efficiency.
However, neem biodiesel blended with up to 20 percent by volume of petrochemical diesel results in a product with a very similar viscosity to conventional diesel, making it more viable for use in compression ignition engines. It also has a slightly lower energy density, or calorific value. The neem biodiesel is of a higher viscosity and density than conventional diesel derived from petroleum oil. Work published in the International Journal of Renewable Energy Technology, reports on the production, characterisation and utilisation of neem biodiesel as a green fuel for vehicle engines.īheru Lal Salvi and Sudhakar Jindal of the Department of Mechanical Engineering at the Maharana Pratap University of Agriculture and Technology in Udaipur, Rajasthan, India, have shown how neem biodiesel can be prepared through a two-stage trans-esterification reaction in approximately 88% yield. It has been used in traditional medicine but has also been investigated for the pest control potential of natural products. The neem tree, Azadirachta indica, also known as the Indian Lilac, is well known for its oil extracted from its seed and fruit.
