Iodinated X-ray contrast media (ICM) are widely used in medical imaging due to their stable properties, but they cannot be effectively removed in wastewater treatment plants (especially hospital wastewater). Therefore, ICM have been widely detected in aquatic environments and may gradually accumulate and cause adverse effects to the creatures. In this paper, the degradation characteristics of two most commonly detected ICM, iohexol and diatrizoate, by ultraviolet/persulfate (UV/PS) were investigated. UV/PS can effectively degrade both ICM, with pseudo-first-order rate constants (kobs) of 0.3641 min−1 for iohexol and 0.3511 min−1 for diatrizoate, and SO4·− played a major role in UV/PS degradation of both ICM. The presence of I−, Cl−, Br−, humic acid (HA), and alkaline conditions inhibited the degradation efficiency of both ICM. Less I-DBPs were formed from iohexol at low PS and high Br− concentrations, but from diatrizoate at high PS and Br− concentrations. The degradation pathways of iohexol and diatrizoate in the UV/PS process were proposed separately according to the detected degradation intermediates. This study can provide an essential theoretical basis for the UV/PS degradation of the two ICM. © 2024 Royal Society of Chemistry. All rights reserved.

Three sliding mode controllers are designed for the control of a photo-voltaic system connected to grid on the nonlinear behavior of the dc-link capacitor and inverter switching input signals. In this proposed system, a nonlinear state space model is used after abc-dq reference frame transformation to design sliding mode control inputs to ensure the maximum power point extraction from the photo-voltaic system and unity power factor in the grid with different sliding manifolds. The performance of three sliding mode controller is compared and it is concluded that the controller based on the power balanced perform better compared to separate current and voltage tracking. Performance of these controller under nominal conditions, parameter variations and load disturbances is validated by the numerical simulation. © 2020

The further decarbonization of power systems with high renewable energy penetration faces the problem of inter-day intermittence of renewable energy sources (RES) and the seasonal imbalance between RES and load demand, due to the limited regulation ability of conventional units such as thermal generation. Regular solutions based on battery energy storage system (BESS) are too costly to be practical. To address issues above, hydrogen energy storage system (HESS) and ammonia energy storage system (AESS) are introduced to gradually replace thermal generation. Specifically, first, HESS and AESS are incorporated into the multi-stage capacity expansion planning (MSCEP) model with carbon emission reduction constraints. Yearly data with hourly time resolution are utilized for each stage to accurately describe the intermittence of RES. Then, an improved column generation (CG) with Dantzig-Wolfe decomposition (DWD) embedded solution approach is used to efficiently solve the large-scale MSCEP model. Finally, a real-life system in China is studied. The results indicate that the proposed method can guarantee high power supply reliability (PSR) under different renewable energy penetration levels, avoiding the low PSR problem that may be caused by the existing typical scenario-based method (TSM) under high penetration (≥30%). Moreover, HESS and AESS are essential to reduce the cost of decarbonization. Especially under the goal of carbon neutrality, the contribution of HESS and AESS in reducing levelized cost of energy (LCOE) reaches 12.28% and 14.59%, respectively, leading to a levelized cost of carbon reduction (LCOCr) of 998 RMB/t. © 2010-2012 IEEE.
