The authors report on the first demonstration of optical fibres based on the Ga:La:S system. Core-clad structures have been fabricated by the rod and tube method and pulled into lengths > 200m. Transmission over the wavelength range I .O to 6.5~~ with fibre loss approaching the absorption and scattering level of the bulk glass. is obtained, opening the possibility of new fibre device applicatio...

Abstract The freshwater production in a conventional solar still (CSS) is very less and it can be enhanced by either enhancing evaporation or condensation rates both the still. Therefore, current investigation focused on rate absorber basin over top glass simultaneously. In this regard, using hollow-finned with energy storage novel pond fibres basin. Likewise, sisal fibre water dripping arrange...

Glass fibres with silicon cores have emerged as a versatile platform for all-optical processing, sensing and microscale optoelectronic devices. Using SiGe in the core extends the accessible wavelength range and potential optical functionality because the bandgap and optical properties can be tuned by changing the composition. However, silicon and germanium segregate unevenly during non-equilibr...

The study implements the consequential life cycle assessment (CLCA) to provide a market based perspective on how overall environmental impact will change when shifting glass fibres to flax fibres as reinforcements in composite fabrication. With certain assumptions, the marginal flax fibre supply is identified to be a combination of Chinese flax fibre (70%) and French flax fibre (30%). Due to in...

Self-healing is receiving an increasing amount of worldwide interest as a method to autonomously address damage in materials. The incorporation of a self-healing capability within fibre-reinforced polymers has been investigated by a number of workers previously. The use of functional repair components stored inside hollow glass fibres (HGF) is one such bioinspired approach being considered. Thi...

The work presented in this paper was undertaken as part of BIOCOMP (2005-2008), a European collaborative project, which developed new classes of engineering composite materials from renewable resources. Comprising twenty five European SMEs and research organisations, this three and a half year project generated a wide range of new biocomposite materials, knowledge-based processes and demonstrat...

The advantages of gallium lanthanum sulphide (GLS) based glass over other competing glasses for active and infrared applications are evident through its low-phonon energy, high rare-earth solubility, high transition temperature and non-toxicity. However this glass often devitrifies during fibre drawing due to a small separation between the crystallisation and fibre drawing temperatures. Improvi...

Glass fibres: absence of pulmonary hazard in production workers. Seventy fibreglass workers with a mean of 19-85 years in the industry are compared with a control group having no exposure to glass fibre but otherwise matched for age, sex, height, and weight, and residing in the same geographical area. Comparison was made by radiography, the administration of the modified Medical Research Counci...
