The ductility of steel depends on its chemical composition. In general, steel’s ductility ranges from 4 to 40%. Steel has been one of the most important metal materials to humanity since its creation in the 13th century BCE. First used in weapons and architecture, steel is still used in ...
Toxic waste, chemical waste material capable of causing death or injury to life. Waste is considered toxic if it is poisonous, radioactive, explosive, or bioaccumulative (that is, increasing in concentration at the higher ends of food chains) or if it ca
While almost all engineering materials are susceptible to MIC. there are three engineering materials that in this chapter we want to study their MIC behaviour and susceptibility with more details. There are three reasons for that: either these materials have a reputation to be toxic to micro-...
It should be noted that there are several entry routes for toxic materials, a few of which are the following: RouteEntryControl Measure IngestionMouthAvoid drinking, smoking, and eating when working near toxins InhalationMouth and noseWear protective equipment and work under the lab's ventilation ...
Pure water appears blue due to the absorption of light in the (electromagnetic wavelength) range of 600 to 800 nanometers. And since it contains no ionic materials or impurities, it’s a bad conductor of electricity. However, its electrical conductivity can be increased by dissolving substances ...
Poisonous substances are toxic when ingested. Venomous creatures inject poison as a form of aggression or self-preservation. A toxic mushroom is poisonous, and a rattlesnake is venomous. Unfortunately, these two words are used interchangeably in everyday speech but have very different meanings ...

First principles study of p-type conductivity in wide band gap Cu3TaQ4 (Q=S,Se,Te) semiconductors A recent study of CuTaQ(Q=S or Se) has shown that these materials exhibit several favorable optoelectronic properties including large optical band gap, tunable visible photoemission, and p-type ...
Density functional theory (DFT): As a method to study the electronic structure of multi-electron systems, DFT is widely applied in the fields of condensed matter physical computational materials science and computational chemistry [45]. Because of the outstanding ability of DFT for simulating Raman ...
During the 1960s chemical companies developed the organotin compounds tributyltin (TBT) and triphenyltin (TPT) as effective self-polishing materials. However, these chemicals were later found to be highly toxic for many aquatic organisms and have been shown to be bioaccumulative and to contaminate th...
