A boron nitride (BN) film was deposited using a reactive radiofrequency magnetron sputtering substrate. The deposition rate was 200nm/hr. The XPS compositional analysis showed that boron-to-nitrogen atomic ratio was 1/1 while the FTIR analysis indicated that the ratio of cubic phase (cBN) to hexagonal (hBN) phase was 55 % t0 45 %. What was the ion-to-deposition flux ratio when the ion current density was 4 mA/cm2? (Deposition area: 1/cm2; cBN mass density: ρcBN =3.48 g/cm3, Boron: Ma = 10.811 g/mol; Nitrogen: Ma = 14.0067 g/mol; hBN mass density: ρhBN =2.25 g/cm3; cBN mass density: ρcBN =3.48 g/cm3)

Cubic boron nitride is used as an abrasive in machining steel as an alternative to diamond, whereas hexagonal boron nitride is frequently used as a lubricant in electronic and high-temperature applications. Explain how these different properties result from different crystal structures and bonding in this material. (Hint: think about the different crystal structures of carbon!)

(For the case of the hexagonal boron nitride and tungsten diselenide, show your physics reasoning on why there is a shift in the phonon mode as the thickness of the materials reduces?) If thickness of material lattice is reduced , the raman shift increases. So, there is shift in phonon mode as the thickness of materials reduces. can someone please explain the physics reasoning of this statement

ATCase perfrorms the first step in CTP synthesis using aspartate as a substrate. It is a wonderful example of allosterism: a) Describe the quartenary structure of ATCase. To get you started remember that the enzyme consists of two different subunits, of which there are 6 of each for a total of 12 subunits. b) What are the functions of the two different subunits? c) what are the allosteric effectors and what is their role in the KM of ATCase?

A wet plastic film comprised of a polymer and acetone has to be dried using a hot stream of gas in a steady state process. The wet film contains 3 kg of a non-volatile polymer for every kg of acetone. Along with the input of the wet film, a second input of hot gas stream at 80°C is used for the drying process. Since the gas stream is obtained from a recovery unit, it contains nitrogen and a residual amount...
