| 1 | Spectroscopic study on transformations of dissolved organic matter in coal-to-liquids wastewater under integrated chemical oxidation and biological treatment process显示文摘A large amount of wastewater containing various toxic organic contaminants is produced during coal-to-liquids process. In this study, several spectroscopic methods were used to monitor the transformation of organic pollutants during an integrated chemical oxidation and biological process. The results showed that the hydrophobic acid fraction increased after Fenton oxidation, which was likely due to the production of small-molecule organic acids. Soluble microbial products were generated during biological treatment processes,which were degraded after ozonation; meanwhile, the hydrophilic base and acid components increased. Ultraviolet-visible spectroscopic analysis indicated that peaks at the absorption wavelengths of 280 and 254 nm, which are associated with aromatic substances, were detected in the raw water. The aromatic substances were gradually removed, becoming undetectable after biological aeration filter(BAF) treatment. Fourier transform infrared spectroscopy analysis revealed that the functional groups of phenols;benzene, toluene, ethylbenzene, and xylene(BTEX); aromatic hydrocarbons; aliphatic acids;aldehydes; and esters were present in raw wastewater. The organic substances were oxidized into small molecules after Fenton treatment. Aromatic hydrocarbons were effectively removed through bioadsorption and biodegradation after BAF process.Biodegradable organic matter was reduced and finally became undetectable after anoxic–oxic treatment in combination with a membrane bioreactor. Four fluorescent components were fractionated and obtained via excitation–emission matrix parallel factor analysis(EEM-PARAFAC). Dissolved organic matter fractionation in conjunction with EEM-PARAFAC was able to monitor more precisely the evolution of characteristic organic contaminants. | Siwei Peng Xuwen He Hongwei Pan | 2018 | Journal of Environmental Sciences2018，30，8： | 9 |
| 2 | Recent advances in designing conductive hydrogels for flexible electronics显示文摘Flexible electronics have emerged as an exciting research area in recent years,serving as ideal interfaces bridging biological systems and conventional electronic devices.Flexible electronics can not only collect physiological signals for human health monitoring but also enrich our daily life with multifunctional smart materials and devices.Conductive hydrogels(CHs)have become promising candidates for the fabrication of flexible electronics owing to their biocompatibility,adjustable mechanical flexibility,good conductivity,and multiple stimuli-responsive properties.To achieve on-demand mechanical properties such as stretchability,compressibility,and elasticity,the rational design of polymer networks via modulating chemical and physical intermolecular interactions is required.Moreover,the type of conductive components(eg,electron-conductive materials,ions)and the incorporation method also play an important role in the conductivity of CHs.Electron-CHs usually possess excellent conductivity,while ion-CHs are generally transparent and can generate ion gradients within the hydrogel matrices.This mini review focuses on the recent advances in the design of CHs,introducing various design strategies for electron-CHs and ion-CHs employed in flexible electronics and highlighting their versatile applications such as biosensors,batteries,supercapacitors,nanogenerators,actuators,touch panels,and displays. | Qiongyao Peng Jingsi Chen Tao Wang Xuwen Peng Jifang Liu Xiaogang Wang Jianmei Wang Hongbo Zeng | 2020 | InfoMat2020，2，5： | 8 |

| 5 | Probing the Interfacial Forces and Surface Interaction Mechanisms in Petroleum Production Processes显示文摘Despite the advances that have been made in renewable energy over the past decade,crude oil or petroleum remains one of the most important energy resources to the world.Petroleum production presents many challenging issues,such as the destabilization of complex oil-water emulsions,fouling phenomena on pipelines and other facilities,and water treatment.These problems are influenced by the molecular forces at the oil/water/solid/gas interfaces involved in relevant processes.Herein,we present an overview of recent advances on probing the interfacial forces in several petroleum production processes(e.g.,bitumen extraction,emulsion stabilization and destabilization,fouling and antifouling phenomena,and water treatment)by applying nanomechanical measurement technologies such as a surface forces apparatus(SFA)and an atomic force microscope(AFM).The interaction forces between bitumen and mineral solids or air bubbles in the surrounding fluid media determine the bitumen liberation and flotation efficiency in oil sands production.The stability of complex oil/water emulsions is governed by the forces between emulsion drops and particularly between interface-active species(e.g.,asphaltenes).Various oil components(e.g.,asphaltenes)and emulsion drops interact with different substrate surfaces(e.g.,pipelines or membranes),influencing fouling phenomena,oil-water separation,and wastewater treatment.Quantifying these intermolecular and interfacial forces has advanced the mechanistic understanding of these interfacial interactions,facilitating the development of advanced materials and technologies to solve relevant challenging issues and improve petroleum production processes.Remaining challenges and suggestions on future research directions in the field are also presented. | Diling Yang Xuwen Peng Qiongyao Peng Tao Wang Chenyu Qiao Ziqian Zhao Lu Gong Yueliang Liu Hao Zhang Hongbo Zeng | 2022 | Engineering2022，，11： | 1 |
| 6 | A Study on Genotype-by-Environment Interaction Analysis for Agronomic Traits of Maize Genotypes Across Huang-Huai-Hai Region in China显示文摘Facing the trend of increasing population,how to increase maize grain yield is a very important issue to ensure food security.In this study,28 nationally approved maize hybrids were evaluated across 24 different climatic conditions for two consecutive years(2018-2019).The purpose of this study was to select high-yield with stable genotypes and identify important agronomic traits for maize breeding program improvement.The results of this study showed that the genotypeenvironment interaction effects of the 12 evaluated agronomic traits was highly significant(P<0.001).We introduced a novel multi-trait genotype-ideotype distance index(MGIDI)to select genotypes based on multiple agronomic traits.The selection process exhibited by this method is unique and easy to understand,so the MGIDI index will have more and more important applications in future multi-environment trials(METs)research.The genotypes selected by the MGIDI index were G22,G10,G12 and G1 as the high yielding and stable genotypes.The parents of these selected genotypes have the ability to play a greater role as the basic germplasm in the breeding process.A new form of genotype(G)main effects and genotype(G)-by-environment(E)interaction(GGE)technician,genotypeyieldtrait(GYT)biplot,based on multiple traits for genotypes selection was also applied in this study.The GYT biplot ranked genotypes by combining grain yield with other evaluated agronomic traits,and displayed the distribution of their traits,namely strengths and weaknesses. | Haiwang Yue Jianwei Wei Junliang Xie Shuping Chen Haicheng Peng Hongmei Cao Junzhou Bu Xuwen Jiang | 2022 | Phyton-International Journal of Experimental Botany2022，91，1： | 1 |
| 7 | Fluorescence imaging analysis of the glioma microenvironment显示文摘Glioma is the most malignant brain cancer.The neurons,macrophages,T cells and other immune ellls constitute the glioma immunosuppressive microenvironment.The accurate spatial distri-bution of these cells in the glioma microenvironment and its relationship with glioma metastasis is unknown.We constructed a mouse gliomna cell line stably expressing the large Stokes shifted yellow fluorescent protein and applied it to the multicolor immunofluorescence imaging.The inaging data revealed that the neurons were sparsely distributed in the glioma core and the mumber of neurons decreased by 90%compared with normal brain site.The spatial distribution of monocyte-macrophages and microglia is heterogeneous.The monocyte macrophages and T cells were heavily recrnuited into the glioma core and metastasis.There was no significant difference in the distribution of microglia amnong glioma core,margin,and normal brain site.Our results provided new perspectives for targeting immune regulation cells and developing new immuno-therapy strategies for glioma. | Xuwen Peng Yuzhou Chen Yuke Wang Shuhong Qi | 2023 | Journal of Innovative Optical Health Sciences2023，16，1： | 0 |

| 9 | Ru/Pt@BSA nanoparticles for efficient photo-catalytic oxidation of NAD(P)H and targeted cancer treatment under hypoxic conditions显示文摘Photo-catalytic oxidation of intracellular nicotinamide adenine dinucleotide(2'-phosphate)(NAD(P)H)has attracted much attention for cancer therapy.However,the general oxygen-dependent mechanism heavily depresses the efficacy in hypoxic tumors.To solve this problem,herein platinum nanoparticles(Pt NPs)with catalase-like(CAT-like)and catalytic H_(2)evolution activities were introduced as a powerful assistant to enhance the photo-catalytic NAD(P)H oxidation of Ru1([Ru(phen)2(PIP-OCH_(3))]^(2+),phen=1,10-phenanthroline,PIP-OCH_(3)=2-(4-methoxy phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline)under hypoxic and even oxygen-free conditions.Firstly,Pt NPs can transform the original and in situ formed H_(2)O_(2)once again into O_(2)by the CAT-like activity,thus relieving tumor hypoxia and realizing cyclic utilization(at least in part)of the precious oxygen in hypoxia.Secondly,Pt NPs can also be served as H_(2)evolution catalysts while using Ru1 as the photosensitizer and NAD(P)H as the electron and proton donor.In this process,NAD(P)H is oxidized without the participation of oxygen,which can provide an effective way even under oxygen-free conditions.Via co-encapsulation of Rul and Pt NPs in bovine serum albumin(BSA)with tumor targeting ability,the resultant Ru/Pt@BSA could photo-catalyze intracellular NAD(P)H oxidation under hypoxic conditions(3%O_(2)),and exhibited an efficient and selective anticancer activity both in vitro and in vivo.Our results may provide new sights for efficient and targeted cancer treatment underhypoxic conditions. | Xuwen Da Xiulian Liu Chao Li Yatong Peng Yao Jian Wanpeng Zhou Yunli Xu Yao Wu Xuesong Wang Qianxiong Zhou | 2023 | Chinese Chemical Letters2023，34，12： | 0 |
