Vibranium is a fictional metal appearing in American comic books published by Marvel Comics, noted for its extraordinary abilities to absorb, store, and release large amounts of kinetic energy. Mined only in Wakanda, the metal is associated with Black Panther, who wears a suit of vibranium, and with Captain America, who bears a vibranium/steel alloy shield. The Wakandan isotope possesses the ability to absorb all vibrations in the vicinity as well as kinetic energy directed at it. The energy absorbed is stored within the bonds between the molecules that make up the substance. As a result, kinetic energy is dissipated within the bonds instead.  The question is , Is there any metal which resembles Vibranium? There is!!! In 2016, Hyperloop Transportation Technologies developed a real-world smart composite material that they named Vibranium. The lightweight carbon fiber material for the Hyperloop pods is reported to provide the passengers double protection against dama...

 The N95 mask is made up of synthetic plastic fibers . This fibers are similar to the fibers in synthetic and polyester shirts many people wear. But what actually is special about it?  The plastic fibers is made up of the polymer polypropylene . Polypropylene is so efficient that it can filter out both large and small particles . The efficiency of N95 is 95% just because of this magical filter material polypropylene. The reason for this efficiency of polypropylene is that its fibers have a random arrangement , imagine a spaghetti on a plate . This randomness enables high particle filtration while remaining highly breathable . So this is the secret material behind the safety of almost everyone. Polypropylene is extensively used for mask productions to ensure our safety from viruses. There is one more reason for such high efficiency of the N95 mask. It is called the electrostatic filtering . On the filtration layer of the mask an electrostatic charge is already present , t...

MICROWAVE PRE-TREATMENT TEST A new pre-treatment technology for the removal of volatile components in the fines based on microwave heating is investigated. Microwave energy is a non-ionising electromagnetic radiation with frequencies in the range of 300 MHz to 300 GHz. Microwave heating is fundamentally different from conventional heating because microwaves take the form of electromagnetic energy and can penetrate deep into the sample. This allows sample heating to be initiated volumetrically, as opposed to conventional thermal processing, which heats the sample from the outside inward via standard heat transfer mechanisms, i.e., through convection, conduction, and radiation. Compared with conventional heating techniques, the main advantages of microwave heating are: non-contact heating, energy transfer rather than heat transfer, saving energy, rapid heating, material selective heating and volumetric heating .Microwave pre-treatment is applied on the fines with high amount of zinc oxid...
