How do you make fabric self healing? To obtain the self healing property, materials are dipped into squid teeth proteins, which were turned into a liquid form using yeast and bacteria. This coating process can be applied to a finished garment or to the threads first, before manufacturing. This simple procedure has a large impact […]
What is continuity equation of flow?
What is continuity equation of flow? In fluid dynamics, the continuity equation states that the rate at which mass enters a system is equal to the rate at which mass leaves the system plus the accumulation of mass within the system. What is meant by continuity of flow? If steady flow exists in a channel […]
How many electrons does a 60 watt light bulb pass per second?
Does oxygen and hydrogen make water?
Does oxygen and hydrogen make water? H-2-Oh no! Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result […]
Is E coli a vector-borne disease?
Is E coli a vector-borne disease? Flies can carry diseases such as typhoid fever, cholera, and dysentery. Cockroaches can carry diseases such as Escherichia coli (E. Coli), and Salmonella food poisoning. Rats and mice can carry diseases such as rat-bite fever, leptospirosis, and Salmonella food poisoning. Can humans be vectors of disease? Many factors affect […]
What type of reaction forms disulfide bonds?
What type of reaction forms disulfide bonds? Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding. The other sulfur-containing amino acid, methionine, cannot form disulfide bonds. How are disulfide bonds broken? Disulfide bonds can be broken by addition of reducing agents. The most common agents […]
What is the principle of Maldi-Tof?
What is the principle of Maldi-Tof? MALDI is the abbreviation for “Matrix Assisted Laser Desorption/Ionization.” The sample for MALDI is uniformly mixed in a large quantity of matrix. The matrix absorbs the ultraviolet light (nitrogen laser light, wavelength 337 nm) and converts it to heat energy. What is the role of Reflectron in Maldi-Tof? A […]
How do freedivers not get the bends?
How do freedivers not get the bends? Free divers really don’t have to worry about decompression sickness (the bends) because they are not breathing compressed air underwater. They are simply taking a breath of air at the surface, descending, and returning to the surface with that same breath of air. Things just go back to […]
Who is credited with creating the first periodic table?
Who is credited with creating the first periodic table? British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. How did Moseley establish more accurate periodic table? by […]
Which is the basic unit of matter?
Which is the basic unit of matter? In turn, the atom is the fundamental unit of matter…, that is, of an element. The number of positively charged protons and neutral neutrons in an atomic nucleus account for most of the mass of an atom. Each negatively charged electron that orbits a nucleus is about 1/2000th […]
