Experimental investigation of bio-diesel droplet ignition
In this work, the ignition delay of bio-diesel and its blends with diesel at one atmosphere pressure and at 900°C temperature has been studied. The results are compared to those for diesel oil. Specifically, the suspended fuel droplet was inserted into a hot furnace containing atmospheric air at temperatures, which varied from 600–900°C. The fuel droplet was suspended on the fine wire of diameter ...

Alternative Energy: Small Molecule Semiconductor Materials to Improve the Luminous Efficiency of OLEDs
Small molecule semiconductor building blocks have special optoelectronic properties that are different from inorganic or polymer semiconductor materials. Compared with inorganic semiconductor materials, there are many types of small-molecule semiconductor materials, and there is a lot of room for the choice of material types. Secondly, molecular synthesis and modification can be used to achieve ...

Biofuel Production from Bacteria
On August 24, 2018, researchers from the University of Kent, UK, published a study on a new technique developed to use bacteria as cell factories to produce biofuels. Working in partnership with scientists from University College London, the University of Bristol, and Queen Mary University of London, Matthew J. Lee et al., uncovered a biotechnical approach to redesign bacterial structures called ...

Impact of gas cluster ion and accelerated neutral atom beam surface treatments on the laser-induced damage threshold of ceramic Yb:YAG
Abstract We describe the application of the gas cluster ion beam (GCIB) and of the accelerated neutral atom beam (ANAB) surface treatments to ceramic Yb:YAG. We demonstrate that these techniques allow accurate control of ceramic Yb:YAG surface characteristics and constitute an alternative to conventional surface finishing techniques. In this study, we analyse the impact of angstrom level ...

Effect of seed particle size and ammonia concentration on the growth of ZnO nanowire arrays and their photoconversion efficiency
ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel coating process. It was found that changing the number of coating process ...

Historical, regulatory and safety aspects of nuclear energy in India
Jawaharlal Nehru, former Prime Minister of India and Homi J. Bhabha interacted closely to set up the Atomic Energy Commission in 1948. The Indian parliament replaced the Atomic Energy Act, 1948 with the Atomic Energy Act, 1962 (AEA 1962) and promulgated appropriate rules. The Department of Atomic Energy (DAE) was set up in 1954. The Indian Cabinet established, through a resolution, a new Atomic ...

Application of Polymer/Macromolecule Semiconductor Building Blocks
Polymer/macromolecule semiconductor building blocks usually have a long conjugated backbone, and their electrons are highly delocalized, which is conducive to charge transport. The intrinsic conductivity of this type of material is not large, but after oxidation or doping, the conductivity can be significantly improved, showing the properties of a conductor or a semiconductor. The band gap of ...

Guidelines Governing Conflict of Interest
In science, a conflict of interest may occur in situations where financial or other personal considerations may bias the professional judgement of an investigator in conducting or reporting research. Conflicts may be real or perceived, harmful or insignificant. Whereas such conflicts may represent the potential for compromised judgement, they do not necessarily indicate the likelihood that such ...

Design, development and performance evaluation of latent heat storage foot warmers
In this paper, three PCM based foot warmers of cylindrical and rectangular in shape were designed, developed and fabricated to store solar energy during sunshine hours. The stored energy was utilised to warm the feet in the late evening to replace electric heaters. By trial experiment, it was found out that the surface temperature of the storage units of the foot warmer should be between ...

Biogas and Anaerobic Digestion in Relation to CH4 Methane Monitoring
The use of biogas as a renewable energy source currently accounts for 10 % of global primary energy consumption1 and is often heralded as the perfect example of the ‘circular economy’ – where waste products can be reused to generate energy for other processes in a self-perpetuating cycle.2Biogas consists of the mixture of gases produced by the breakdown of organic matter by bacteria under ...
