Wanyue Xiao, Rui Geng, Duohang Bi, Yi Luo, more

Small > 20 > 30 > n/a - n/a

Traditional lipid nanoparticles (LNPs) suffer from low drug loading capacity (DLC), weak stability, and lack of responsiveness. Conventional approaches to address these issues involve the synthesis of lipid‐prodrug by incorporating responsive covalent linkers. However, such approaches often result in suboptimal sensitivity for drug release and undermine therapeutic effectiveness. Herein, the study...

Yi Zhang, Xiangpeng Xiao, Weilun Chen, Zihan Zhang, more

Small > 20 > 29 > n/a - n/a

Silicon (Si) anode has attracted broad attention because of its high theoretical specific capacity and low working potential. However, the severe volumetric changes of Si particles during the lithiation process cause expansion and contraction of the electrodes, which induces a repeatedly repair of solid electrolyte interphase, resulting in an excessive consuming of electrolyte and rapid capacity decay...

Shuailing Ma, Yongsheng Zhao, Hailong Li, Robert Farla, more

Small > 20 > 5 > n/a - n/a

Transparent nano‐polycrystalline diamond (t‐NPD) possesses superior mechanical properties compared to single and traditional polycrystalline diamonds. However, the harsh synthetic conditions significantly limit its synthesis and applications. In this study, a synthesis routine is presented for t‐NPD under low pressure and low temperature conditions, 10 GPa, 1600 °C and 15 GPa, 1350 °C similar with...

Zihan Zhang, Liangju Zhao, Ninglian Wang, Hang Liu, more

Hydrological Processes > 38 > 1 > n/a - n/a

Stable isotopic compositions of precipitation (δ¹⁸O_p, δ²H_p and d‐excess_p) and atmospheric vapour (δ¹⁸O_v, δ²H_v and d‐excess_v) with high spatial–temporal resolution are crucial in revealing hydrologic cycle. Based on the variation characteristics of δ¹⁸O_p/δ¹⁸O_v, δ²H_p/δ²H_v and d‐excess_p/d‐excess_v in the headwaters of the Shule River (HSR) on hourly and daily scales from June to September 2018, this study...

Load regulation application of university campus based on solar power generation forecasting

Guozheng Han, Shujuan Tan, Zihan Zhang

Archives of Electrical Engineering > 2023 > Vol. 72, nr 2 > 429--441

For a solar photovoltaic power system on a university campus, the electricity generated by the system meets the campus load, and the extra electricity is delivered to the grid. Generally, the price of the photovoltaic system is cheaper than that of the utility power system. The full use of solar electricity can reduce the electricity cost of the school. The deep belief network is used to predict solar...
