Plasmonic Au nanoparticles supported on both sides of TiO2 hollow spheres for maximising photocatalytic activity under visible light

Jianwei Lu, Lan Lan, Xiaoteng Terence Liu, Na Wang, Xiaolei Fan

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 4,   Pages 665-671 doi: 10.1007/s11705-019-1815-2

Abstract: A strategy of intensifying the visible light harvesting ability of anatase TiO hollow spheres (HSs) was developed, in which both sides of TiO HSs were utilised for stabilising Au nanoparticles (NPs) through the sacrificial templating method and convex surface-induced confinement. The composite structure of single Au NP yolk-TiO shell-Au NPs, denoted as Au@Au(TiO , was rendered and confirmed by the transmission electron microscopy analysis. Au@Au(TiO showed enhanced photocatalytic activity in the degradation of methylene blue and phenol in aqueous phase under visible light surpassing that of other reference materials such as Au(TiO by 77% and Au@P25 by 52%, respectively, in phenol degradation.

A comprehensive review of optical wireless power transfer technology Review

Syed Agha Hassnain MOHSAN, Haoze QIAN, Hussain AMJAD,Hassnainagha@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 6,   Pages 767-800 doi: 10.1631/FITEE.2100443

Abstract: Ground-breaking (OWPT) techniques have gained significant attention from both academia and industry in recent decades. Powering remote systems through s (LDs) to either operate devices or recharge batteries offers several benefits. Remote LDs can remove the burden of carrying extra batteries and can reduce mission time by removing battery swap-time and charging. Apart from its appealing benefits, laser power transfer (LPT) is still a challenging task due to its low transfer efficiency. In this paper, we discuss the necessity and feasibility of OWPT and discuss several projects, working principle, system design, and components. In addition, we show that OWPT is an essential element to supply power to Internet-of-Things (IoT) terminals. We also highlight the impacts of dynamic OWPT. We outline several OWPT techniques including optical beamforming, (DLC), adaptive-DLC (ADLC), simultaneous lightwave information and power transfer (SLIPT), Thing-to-Thing (T2T) OWPT, and high intensity laser power beaming (HILPB). We also deal with laser selection, hazard analysis, and received photovoltaic (PV) cell selection for OWPT systems. Finally, we discuss a range of open challenges and counter measures. We believe that this review will be helpful in integrating research and eliminating technical uncertainties, thereby promoting progress and innovation in the development of OWPT technologies.

A rain-on-snow mixed flood forecast model and its application

Jian WU, Lan LI,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 4,   Pages 440-444 doi: 10.1007/s11709-009-0051-0

Abstract: Based on summarizing the rule of rainstorm and snowmelt mixed flood, the structure of rain-on-snow runoff-generation is discussed; and critical temperature is used to determine the form of precipitation and snowmelt factor, taking into account rainfall volume of snowmelt. A rain-on-snow flood forecast model is developed by combining LL-Ⅰdistributed hydrology model. The Kalangguer River, an internal river in Xinjiang Autonomous Region, is taken for example. It is indicated that the model has a higher precision of forecasting; its determinacy coefficient is greater than 0.80.
