Water is one of the necessities that life needs to survive. If there was no water there would be no life on earth. Water is the main basis for the ecosystem and throughout the most recent years, man is finding more and more uses for water including sanitation and produce. But in order for water to achieve it’s uses and maintain a balanced biological life, there must be a level of water quality maintained within it. There are many factors that affect the life of water bodies that include;…

Metal plays a key role in development and it is the backbone for the manufacturing industry. For years, various metal have been extracted from the mineral ore found in nature, but with the time high grade ore have is getting depleted and the option at left with us is to processing low grade ore which makes recovery process expensive. In such scenario recycling metals seems a lucrative option as it helps environment by reducing the amount of scrap or waste material getting disposed into…

Paying special attention to its general, mechanical, thermal, electrical, optical and environmental properties, suitable materials were listed, limited and compared, utilizing the Selection Data tools in the form of graphs, limitations and trees. Material Possible Utilisation Properties Age-Hardening wrought Al alloy…

1. INTRODUCTION Graphene is the most required engineering material in the twenty first century, largely due to its exceptional mechanical, thermal and electrical properties. For Example monolayer of graphene sheet has Young’s modulus of about 1 TPa [Ref], shear modulus of 280 GPa [Ref], fracture strength of 130 GPa [Ref], thermal conductivity of 5000 W/mK [Ref], longitudinal sound velocity of 20Km/s [Ref], melting temperature of 4900 K [Ref] and also it has high electron mobility of 250,000…

the waste glass should be separated according to various colors. Electric separation is a method using different electrical properties of components in high voltage electric field to separate wastes. This technology is mainly used in developed countries, but rare in underdeveloped or developing countries. Electrostatic separation technology depends on the difference in the conductivity, thermoelectric effect, and charged function and can be used for the separation of all types…

diamonds as semi-conductors. (1) They are too expensive to use in such a scaled up way (2) Never consistent and steady supply of large pure diamonds and they did not have the same electrical properties, but CVD fixed that problem. (3) No one has been able to produce a negatively charged diamond with significant conductivity to form microchip…

Results An initial resistance versus magnetic field measurement on NdMo16O44 reveals a pronounced magnetic hysteresis effect when a magnetic field is applied perpendicular to the current, but with unknown orientation with respect to the crystal axes, as shown in Fig. 2a for temperatures from 12K to 30K (at temperature below 12K, the overall resistance is too high to produce low-noise measurements with resolvable magnetoresistance features). The individual plots are offset to better show the…

and high clay contain in the soil. Ground penetrating radar may not be suitable for investigations of certain sites, like in areas where soils have high clay contents that rapidly reduces the radar signal and results in poor penetration depths, electrical resistivity surveys could be used instead to identify anomalous areas for follow-up investigations (Pringle & Jervis, 2010). Earth resistance is one of the few geophysical methods that actually works better in soil that has…

Metals What is a metal? A metal is a substance, which have distinctive qualities of particular type. Metals usually are shiny, hard opaque and good conductors. In ancient Latin and Greek it has been written that Theophrastus and Pliny The Elder were the ones who crated metals by characterising the chemical and physical properties. Theophrastus is a Greek philosopher who lived during 371-287 B.C. Pliny the Elder during AD 23-79 was a Roman author, naturalist and naturalist philosopher. During…

Carcinogenic Chemical Product: Fire Retardants Fire safety is a vital part of the modern technological society and as responsible citizens it is important to recognise that, with the aid of fire retardants, there is a prolong time frame of escaping from fires. This widely used carcinogenic product is composed of certain chemical elements within numerous everyday products (either inside the polymeric material or as an external layer) that help combat the ignition through chemical reactions at…
