Hawk, this sentence is very significant in that article -
"...due to the nature of their synthesis, the results have not been reproducible—not every device made with quantum dots behaved the same way."
It is saying that for quantum dots made by batch synthesis, results are not the same everytime. However, QD made with continuous flow process can be the same every time because the process is reproducible. That's the QMC way. The article's researchers may not have been exposed to continuous flow process and its advantages.
Another different point is that although QD seem to start at just over one nanometer in size, because QMC makes product by mixing chemicals from the ground up, it can theoretically or potentially make molecules such as single elements, precious metals and metal oxides that are smaller than one nanometer, but it is harder to assure uniformity of size the smaller the molecule. There is less leeway for error in timing and temperature in the process. That is an industrywide problem. Blue quantum dots are therefore harder to make, and uniformly, than red and green because they are smaller, and QMC's announcement of their manufacture by continuous flow process is a major advance.
Most companies would be very happy with molecules in the low nanometers for single metals or metal oxides that are uniform, because that does not exist cost-effectively now, and they must use materials in the hundreds of nanometers or micron size with great size variance. Its also possible some of these nanomaterials could have the quantum effect - objects in the nanometer size have characteristics and abilities not seen in larger sizes. One example would be gold or silver nanomolecules in an ink - the smaller the size, it is possible that less actual material might be needed for the same function, or might have less electrical resistance or greater conductance; or platinum as a catalyst because the smaller the size, the greater surface ratio, the better the function. These are potential future revenue streams that will be pursued when some company makes it worth QMC's time.
