A BSTRACT Nanocrystalline cerium dioxide is a promising inorganic UV filter for sunscreen applications due to its high UV absorbance and non-toxicity to normal cells. Nanoscale CeO 2 also showed selective cytotoxicity to cancer cells, thus ceria-containing materials are now regarded for the creation of both preventive and therapeutic compositions. At the same time, the interaction of ceria nanoparticles with cell membranes and phosphate-rich components of sunscreen compositions arise the interest to biocompatibility of ceric phosphates. Crystalline cerium(IV) phosphates can be a promising alternative for nanoscale CeO 2 due to their low solubility, high redox stability and UV protective property. However, to date, there is no information on their toxicity to cancer cells. In this work, using the MTT, Live/Dead and MMP assays, we demonstrated for the first time that the inhibitory impact of ceric phosphates Ce(PO 4 )(HPO 4 ) 0 . 5 (H 2 O) 0 . 5 and NH 4 Ce 2 (PO 4 ) 3 on murine melanoma B16/F10 cell line in vitro is comparable to that of nanoscale CeO 2 , at high (500–1000 µ g/ml) concentrations.

Numerically, a theoretical analysis of the noise impact caused by spontaneous Raman scattering, four-wave mixing, and linear channel crosstalk on the measurement-device-independent continuous variable quantum key distribution systems is conducted. The analysis considers symmetry and asymmetry of system paths, as well as possible channel allocation schemes, for a quantum channel located in C- and O-bans. Mathematical models for MDI CV-QKD system and the contributing noises description are provided. The secure key generation rate is estimated to state features of protocol operation when integrated with existing DWDM systems in the context of its implementation into telecommunication networks.

A BSTRACT In the present paper, investigations of nonlinear optical rectification, absorption coefficient and refractive index in a 1D Ga x Al 1 − x As/GaAs/Ga x Al 1 − x As quantum dots under a finite square well potential using simulation software such as COMSOL Multi-Physics and Matlab have been carried out in the presence of electric field, hydrostatic pressure and temperature. Results show that the resonant peaks of ORC (optical rectification coefficient) exhibit a blue shift under increasing of the electric field, while a red shift trailed by a blue shift is displayed under increasing of hydrostatic pressure and temperature. Similar trends take place for the refractive index as well as for the absorption coefficient under changing of the electric field, temperature and hydrostatic pressure. The attained theoretical results would pave a novel opportunity in designing, optimizing and applications of nonlinear opto-electronic devices by tuning the performance of the quantum dots and controlling some of their specific properties.
本文利用COMSOL multiphysics和Matlab等仿真软件，在电场、静水压力和温度存在的情况下，研究了有限平方阱电位下一维Ga x Al 1−x As/GaAs/Ga x Al 1−x As量子点的非线性光整流、吸收系数和折射率。结果表明:电场增大时，光整流系数谐振峰呈现蓝移，静水压力和温度增大时，谐振峰呈现红移后蓝移;在电场、温度和静水压力的变化下，折射率和吸收系数也有类似的变化趋势。所获得的理论结果将通过调整量子点的性能和控制其某些特定特性，为非线性光电器件的设计、优化和应用提供新的机会。
