AbstractA reliable, efficient and electrically-pumped Si-based laser is considered as the main challenge to achieve the integration of all key building blocks with silicon photonics. Despite the impressive advances that have been made in developing 1.3-μm Si-based quantum dot (QD) lasers, extending the wavelength window to the widely used 1.55-μm telecommunication region remains difficult.

Highly Diastero- and Enantioselective C2 Addition of 5H-Oxazol-4-ones to γ-keto-α, β-unsaturated Esters Lin Li,   Mei Wang,   Jiawei Zhou,   Fei Li  and  Huiyun Liu   Abstract A direct C2-addition of 5H-Oxazol-4-ones to γ-keto-α, β-unsaturated esters catalyzed by a chiral squaramide has been achieved. Diverse highly functionalized γ-keto esters bearing a C2-oxazolone at α–position were afforded in high yields with excellent stereoselectivities (d. r.
