Synthesis of LAuNRs
The LAuNRs were synthesized by using a modified seeded growth method described by Murphy et al. recently [31].
Results and discussion Since the seminal reports by Wang et al. [34], Murphy et al. [35], and El-Sayed et al. [36], seeded growth of AuNRs in the presence of cationic surfactant CTAB has been continuously optimized and become the most prevalent growth method for AuNRs.

Introduction
For the jet refrigeration system, it was found that the constant pressure mixing ejector is more widely used than the constant area ejector, because it has a better performance than that of constant area mixing ejector.[1]The constant pressure model was firstly developed by Eames,[2] and confirmed by El-Dessouky et al. in their study. [3] El-Dessouky et al. also created another easy semi-empirical model to predict the entrainment ratio with experimental data from experiments [2,4,5-10]on steam ejectors.

The massive interest in robust optimization over thepast fifteen years was triggered by the work of Ben-Tal and Nemirovski, e.g. [1, 6, 2] and El Ghaoui et
al. [7, 8].
This has been proposed by Ben-Tal and Nemirovski, e.g. [1, 6, 14], and El Ghaoui et al. [7, 8] for conic optimization problems and has been adjusted to general nonlinear optimization problems with state equations by Diehl et al
