of quantum dot and mix the phospors(PMMA).
These quantum dots have three different size : 2.9nm, 3.4nm, 4.3nm in diameter. Each of them absorb different energy and emit the different light color(2.9nm-555nm, 3.4nm-580nm, 4.3nm-625nm). As combined with light that blue chip emitted, this material can emit the white color light.
This structure is very simple, but the problem of this structure is
1. Introduction - L'Oreal
1.1. History
In 1907, Eugène Schueller, a young French chemist, developed an innovative hair-color formula. He called his improved hair dye Auréole. With that, the history of L’Oréal began. Eugène Schueller formulated and manufactured his own products, which he then sold to Parisian hairdressers.
In 1909, Schueller registered his co
of Information Technologies to compete among its competitors. This report is to examine the organization structure, value chain and UNIQLO’s competitor analysis. This report will discuss the history of UNIQLO, the characteristics of the Asia markets and the western countries retail industry. In addition, this report will also analyze the different types of management systems that UNIQUE had mak
