Fastness properties of the flower of Spathodea campanulata and Cordia sebestena dyed cotton fabric have been studied using different combination (1:3,1:1 and 3:1) of various mordants, such as myrobolan:nickel sulphate, myrobolan: aluminium sulphate, myrobolan: potassium dichromate, myrobolan: ferrous sulphate and myrobolan: stannous chloride. The wash, rub, light and perspiration fastness of the dyed samples have been evaluated. Comparing the fastness properties and colour strength of flower of Spathodea campanulata and Cordia sebestena dyed cotton by using combination of mordants. In the comparative study of fastness properties and colour strength of the dyed cotton samples Spathodea campanulata in simultaneous mordanting method with 1:3 mordant combination gives better results than using flower of Cordia sebestena.

Phase homogeneity and crystal structure of Sb88Te12 alloy synthesized by melt-quench method have been analyzed using X-ray diffraction (XRD) and Raman spectroscopy. Rietveld refinement of crystal structure of Sb88Te12 has revealed the formation of Sb8Te3 and Sb phases respectively with 11R and A7 structures (space group is R3m). Phase fractions of the phases Sb 8Te3 and Sb have been determined to be 44.44% and 55.56% respectively. Raman spectrum of Sb88Te12 has showed a highest intensity peak at 156 cm-1 and another peak at 151.1 cm -1, which correspond to A1g modes of Sb8Te 3 and element Sb, respectively. Analysis of Raman spectrum has substantiated the results obtained from structure refinement regarding the presence of two different phases. © The Chinese Society for Metals and Springer-Verlag Berlin Heidelberg.

Bleached cotton fabric was dyed with natural dyes obtained from the flower of Plumeria species. The colour fastness properties and colour strength of dyed cotton fabric were determined and compared. From the comparative study of fastness properties and colour strength of the dyed cotton samples, Plumeria species in simultaneous mordanting method with 3% mordant combination gives better results. © 2015, Sphinx Knowledge House.

Purpose – The purpose of this paper is to extract the eco-friendly natural dye obtained from the flower of Spathodea campanulata and apply on silk fabric using combination of mordants. The fastness properties of the flower of Spathodea campanulata dyed silk fabric have been studied using different combination (1:3, 1:1 and 3:1) of various mordants, such as myrobolan: nickel sulphate, myrobolan: aluminium sulphate, myrobolan: potassium dichromate, myrobolan: ferrous sulphate and myrobolan: stannous chloride. The wash, rub, light and perspiration fastness of the dyed samples have been evaluated. Design/methodology/approach – For dyeing there are three methods are used. They are Pre mordanting, Simultaneous mordanting and Post mordanting methods. Dyed silk materials are tested by using wash fastness, rub fastness, light and perspiration fastness methods. Findings – It is found that Spathodea campanulata dye can be successfully used for the dyeing of silk to obtain a wide range colours by using various combinations of mordants. With regards to colour fastness, test samples exhibit excellent fastness to washing, rubbing, except for pre-mordanting using myrobolan: potassium dichromate combination; and good to excellent fastness to perspiration in both acidic and alkaline media. Originality/value – Availability of literature related to this work is not available. The study of combination of mordants of this natural dye on silk is a new research work and the large scale preparation is definitely very useful to the society. © 2016, © Emerald Group Publishing Limited.

Liquefied petroleum gas (LPG) is one of the most convenient sources of fuel for cook stoves. The main reasons why LPG is widely adopted for house hold are: it is convenient to operate, easy to control, and clean to use because of the blue flame emitted during cooking. However, because of the continued increase in the price of oil in the world market, the price of LPG fuel had gone up tremendously and is continuously increasing at a fast rate. With this problem on the price of LPG fuel, research centres and institutions are challenged to develop a technology for cooking that will utilize alternative sources other than LPG. The potential of biomass as alternative fuel source to replace LPG is a promising option. Henceforth this project work focus on fabricating an environmental friendly, low cost, fixed bed (down draft) biomass gasifier that completely utilize producer gas and converts it into efficient energy resource. © 2006-2015 Asian Research Publishing Network (ARPN).
