Generation of enhanced stability of SnO/In(OH)/InP for photocatalytic water splitting by SnO protection layer

Frontiers in Energy 2021, Volume 15, Issue 3,   Pages 710-720 doi: 10.1007/s11708-021-0764-x

Abstract: InP shows a very high efficiency for solar light to electricity conversion in solar cell and may present an expectation property in photocatalytic hydrogen evolution. However, it suffers serious corrosion in water dispersion. In this paper, it is demonstrated that the stability and activity of the InP-based catalyst are effectively enhanced by applying an anti-corrosion SnO layer and In(OH)3 transition layer, which reduces the crystal mismatch between SnO and InP and increases charge transfer. The obtained Pt/SnO/In(OH)3/InP exhibits a hydrogen production rate of 144.42 µmol/g in 3 h under visible light illumination in multi-cycle tests without remarkable decay, 123 times higher than that of naked In(OH)3/InP without any electron donor under visible irradiation.

Decreasing complexity of glucose time series derived from continuous glucose monitoring is correlated

Frontiers of Medicine 2023, Volume 17, Issue 1,   Pages 68-74 doi: 10.1007/s11684-022-0955-9

Abstract: Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual’s health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique “continuous glucose monitoring” (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

Blasting Technologies of Decreasing Vibration in Subway Tunnel Underpass Adjacent Upper Buildings

Fang Junbo

Strategic Study of CAE 2014, Volume 16, Issue 11,   Pages 58-64

Abstract:

Reduce the blasting vibration is important for blasting excavation in subway tunnel construction. Take the 3rd bid section of Line 3 of Qingdao subway project for example, the distance between tunnel vault and ground is 5~8m, in order to insure the safety of the upper buildings, technologies of parallel cut with big empty hole, one-time initiation and delay by parts, and multiply short holes were adopted in the project. The results show that the maximum value of vertical vibration limited in the criterion allowance, and the upper buildings was intact. Besides, problems of shock conducting tube detonator delay number difficulty to meet large cross-section tunnel blasting excavation requirements, multiple cross-section can’t initiation simultaneous, and low construction efficiency were solved, which ensure the construction safety and schedule.

Multi-Objective Adaptive Optimization Model Predictive Control: Decreasing Carbon Emissions from a Zinc Article

Ke Wei, Keke Huang, Chunhua Yang, Weihua Gui

Engineering 2023, Volume 27, Issue 8,   Pages 96-105 doi: 10.1016/j.eng.2023.01.017

Abstract:

The zinc oxide rotary kiln, as an essential piece of equipment in the zinc smelting industrial process, is presenting new challenges in process control. China's strategy of achieving a carbon peak and carbon neutrality is putting new demands on the industry, including green production and the use of fewer resources; thus, traditional stability control is no longer suitable for multi-objective control tasks. Although researchers have revealed the principle of the rotary kiln and set up computational fluid dynamics (CFD) simulation models to study its dynamics, these models cannot be directly applied to process control due to their high computational complexity. To address these issues, this paper proposes a multi-objective adaptive optimization model predictive control (MAO-MPC) method based on sparse identification. More specifically, with a large amount of data collected from a CFD model, a sparse regression problem is first formulated and solved to obtain a reduction model. Then, a two-layered control framework including real-time optimization (RTO) and model predictive control (MPC) is designed. In the RTO layer, an optimization problem with the goal of achieving optimal operation performance and the lowest possible resource consumption is set up. By solving the optimization problem in real time, a suitable setting value is sent to the MPC layer to ensure that the zinc oxide rotary kiln always functions in an optimal state. Our experiments show the strength and reliability of the proposed method, which reduces the usage of coal while maintaining high profits.

The Significant Contribution of Small-Sized and Spherical Aerosol Particles to the Decreasing Trend in Article

Ke Gui, Huizheng Che, Lei Li, Yu Zheng, Lei Zhang, Hujia Zhao, Junting Zhong, Wenrui Yao, Yuanxin Liang, Yaqiang Wang, Xiaoye Zhang

Engineering 2022, Volume 16, Issue 9,   Pages 82-92 doi: 10.1016/j.eng.2021.05.017

Abstract:

The optical and microphysical properties of aerosols remain one of the greatest uncertainties associated with evaluating the climate forcing attributed to aerosols. Although the trends in aerosol optical depth (AOD) at global and regional scales have been widely examined, little attention has been paid to the trends in type-dependent AODs related to aerosol particle properties. Here, using the aerosol optical component dataset from the Multi-angle Imaging SpectroRadiometer (MISR) instrument, we investigate decadal-scale trends in total aerosol loading as well as AODs for five aerosol components by particle size and morphology during 2003–2018 over land. Relationships between the total AOD (TAOD) trends and type-dependent AOD changes were examined, and the relative contribution of each type-dependent AOD to the overall TAOD trends was quantified. By dividing the TAOD values into four different aerosol pollution levels (APLs) with splits at 0.15, 0.40, and 0.80, we further explored the relationships between TAOD changes and interannual variations in the frequency-of-occurrences (FoOs) of these APLs. Long-term trends in FoOs in the different APLs show that there was a significant improvement in air quality between 2003 and 2018 in most land areas, except South Asia, corresponding to a shift from lightly polluted to clean conditions. However, the effects of different APLs on TAOD changes are regionally dependent and their extent of correlation varied spatially. Moreover, we observed that the annual mean TAOD has decreased by 0.47%·a−1 over land since 2003 (P < 0.05). This significant reduction was mainly attributed to the continued reduction in small-sized (< 0.7 mm diameter) AOD (SAOD) (−0.74%·a−1) and spherical AOD (SPAOD) (−0.46%·a−1). Statistical analysis shows that SAOD and SPAOD respectively accounted for 57.5% and 89.6% of the TAOD, but contributed 82.6% and 90.4% of the trend in TAOD. Our study suggests that small-sized and spherical aerosols composed of sulfate, organic matter, and black carbon play a dominant role in determining interannual variability in land TAOD.
