制备和比较明胶/藻酸盐(GA),明胶/透明质酸盐(GH)和壳聚糖/透明质酸盐(CH)交联海绵,含有或不含有磺胺嘧啶银(AgsD)的6种不同海绵应用于治疗背部全厚度皮肤损伤的Wistar老鼠。这种皮肤损伤的组织学和表皮伤口愈合速度的研究是借助光学显微镜和计算机的形态测量学5d和12d后的后期工作。在对我们的全厚度损伤试样(直径1cm)的治疗中,总体上说,含AgsD的海绵具有优良的伤口愈合能力。然而,明胶基海绵(GA,GH)和CH的伤口愈合的区别显得更有意义。通过对组织学研究结果和计算机化的形态测量学的表皮愈合分析发现,含AgsD的CH作为创伤敷料具有最强的伤口愈合能力。

We investigated the emission properties of Eu3+-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3+emission by codoping of Bi3+and Li+.Eu3+singly doped,Eu3+and Bi3+doubly doped,and Eu3+,Bi3+,and Li+triply doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3+in the singly doped samples are significantly improved by the codoping of Bi3+,mainly due to the energy transfer from Bi3+to Eu3+.The additional codoping of Li+is found to increase the Eu3+emission *** improvement might be attributed to the increase in the photoluminescent quantum yield originating from larger grain sizes and better crystallinity.A detailed analysis of the X-ray diffraction pattern and the asymmetric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3+in GdNbO4does not change significantly with the codoping of Bi3+and Li+.Our results indicate that Li+doping is a promising way to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.

A chemo-mechanical model is developed to investigate the effects on the stress development of the coating of polycrystalline Ni-rich LiNixMnyCo_(z)O_(2)(x≥0.8)(NMC)particles with poly(3,4-ethylenedioxythiophene)(PEDOT).The simulation results show that the coating of primary NMC particles significantly reduces the stress generation by efficiently accommodating the volume change associated with the lithium diffusion,and the coating layer plays roles both as a cushion against the volume change and a channel for the lithium transport,promoting the lithium distribution across the secondary particles more ***,the lower stiffness,higher ionic conductivity,and larger thickness of the coating layer improve the stress *** paper provides a mathematical framework for calculating the chemo-mechanical responses of anisotropic electrode materials and fundamental insights into how the coating of NMC active particles mitigates stress levels.
