For a particular medical procedure, a patient must be injected with a specific number of nanoparticles. You have a batch of spherical, solid gold nanoparticles each with a diameter of 33.0 nm. Because these particles are too small to be weighed individually, you must calculate the mass one nanoparticle in order to determine the total weight of material needed for the procedure. Note: The atomic weight of gold is 196.97 g/mol and the atomic radius is 0.144 nm. The crystal...
Calculate the number of atoms in a 1.4 nm diameter platinum nanoparticle using the total number of unit cells present. Consider a FCC unit cell with a lattice constant of a = 3.91 Å. Explain the interest in small platinum or palladium nanoparticles for catalysis.
What is the amount of gold atoms in a sphere that is 14 nm in diameter when gold is a face-centered cubic structure that has a unit cell edge length of 4.08 Å. There are four gold atoms per unit cell.

psdt. Part C is data collected in the second picture
1. Based on the fact that the citrate anions cover the surface of each nanoparticle, explain what keeps the nanoparticles from sticking together (aggregating) in the original solution. 2. Why does adding the salt solution produce a different result from adding the sugar solution? 3. How could the effect in part C be used to detect the binding of biomolecules, such as DNA or antibodies, that stick...

Question 3 5 pts Gold nanoparticles are typically prepared by the reduction of aurochloric acid (HAUCla) with boiling sodium citrate. The sodium citrate is used in excess and it is assumed that 100% of the Au atoms end up as part of the nanoparticles. If you start with a 1.00% (w/w) aqueous solution of HAC14:3H20 (aurochloric acid is typically available as the trihydrate) and the average particle diameter is 20.0 nm, what is the concentration of Au nanoparticles in the...

5 Nanoparticles of Si in various sizes are routinely fabricated in research. Suppose a Si nanoparticle (usually a sphere) has a radius of 50nm, determine how many Si atoms are there How many Si atoms are there if the radius is 5nm? 6. A Si wire of diameter 24m and length 200 micrometers has a resistance of 1000 ohms. Determine the resistivity of that Si in terms of ohm-cm. Suppose you make the same...
A fullerene is any spherical, ellipsoidal, or cylindrical molecule that consists only of carbon atoms. The first fullerene to be discovered was C60, which consists of 60 carbon atoms arranged in linked hexagonal rings, resembling the pattern formed by the stitching on a soccer ball. (a) Approximating the C60 molecule as a hollow spherical shell with a diameter of 0.684 nm, what is its moment of inertia about an axis through its center? Each carbon atom has a mass of...
