| 1 | Feasibility of bioleaching combined with Fenton oxidation to improve sewage sludge dewaterability显示文摘A novel joint method of bioleaching with Fenton oxidation was applied to condition sewage sludge. The specific resistance to filtration(SRF) and moisture of sludge cake(MSC) were adopted to evaluate the improvement of sludge dewaterability. After 2-day bioleaching, the sludge p H dropped to about 2.5 which satisfied the acidic condition for Fenton oxidation.Meanwhile, the SRF declined from 6.45 × 1010 to 2.07 × 1010s2/g, and MSC decreased from91.42% to 87.66%. The bioleached sludge was further conditioned with Fenton oxidation. From an economical point of view, the optimal dosages of H2O2 and Fe2+were 0.12 and 0.036 mol/L,respectively, and the optimal reaction time was 60 min. Under optimal conditions, SRF,volatile solids reduction, and MSC were 3.43 × 108s2/g, 36.93%, and 79.58%, respectively. The stability and settleability of sewage sludge were both improved significantly. Besides,the results indicated that bioleaching-Fenton oxidation was more efficient in dewatering the sewage sludge than traditional Fenton oxidation. The sludge conditioning mechanisms by bioleaching-Fenton oxidation might mainly include the flocculation effects and the releases of extracellular polymeric substances–bound water and intercellular water. | Changgeng Liu Panyue Zhang Chenghua Zeng Guangming Zeng Guoyin Xu Yi Huang | 2015 | Journal of Environmental Sciences2015，27，2： | 12 |
| 2 | Overview of key operation factors and strategies for improving fermentative volatile fatty acid production and product regulation from sewage sludge显示文摘In recent years,volatile fatty acid(VFA)production through anaerobic fermentation of sewage sludge,instead of methane production,has been regarded as a high-value and promising roadmap for sludge stabilization and resource recovery.This review first presents the effects of some essential factors that influence VFA production and composition.In the second part,we present an extensive analysis of conventional pretreatment and co-fermentation strategies ultimately addressed to improving VFA production and composition.Also,the effectiveness of these approaches is summarized in terms of sludge degradation,hydrolysis rate,and VFA production and composition.According to published studies,it is concluded that some pretreatments such as alkaline and thermal pretreatment are the most effective ways to enhance VFA production from sewage sludge.The possible reasons for the improvement of VFA production by different methods are also discussed.Finally,this review also highlights several current technical challenges and opportunities in VFA production with spectrum control,and further related research is proposed. | Wei Fang Xuedong Zhang Panyue Zhang Jijun Wan Hongxiao Guo Dara S.M.Ghasimi Xavier Carol Morera Tao Zhang | 2020 | Journal of Environmental Sciences2020，32，1： | 9 |
| 3 | Invariance principles for the law of the iterated logarithm under G-framework显示文摘We obtain a general invariance principle of G-Brownian motion for the law of the iterated logarithm(LIL for short). For continuous bounded independent and identically distributed random variables in G-expectation space, we also give an invariance principle for LIL. In some sense, this result is an extension of the classical Strassen's invariance principle to the case where probability measure is no longer additive. Furthermore,we give some examples as applications. | WU PanYu CHEN ZengJing | 2015 | Science China Mathematics2015，58，6： | 7 |
| 4 | Sewage sludge disintegration by high-pressure homogenization: A sludge disintegration model显示文摘High-pressure homogenization (HPH) technology was applied as a pretreatment to disintegrate sewage sludge. The effects of homogenization pressure, homogenization cycle number, and total solid content on sludge disintegration were investigated. The sludge disintegration degree (DDCOD), protein concentration, and polysaccharide concentration increased with the increase of homogenization pressure and homogenization cycle number, and decreased with the increase of sludge total solid (TS) content. The maximum DDCOD of 43.94% was achieved at 80 MPa with four homogenization cycles for a 9.58 g/L TS sludge sample. A HPH sludge disintegration model of DDCOD= kNaPb was established by multivariable linear regression to quantify the effects of homogenization parameters. The homogenization cycle exponent a and homogenization pressure exponent b were 0.4763 and 0.7324 respectively, showing that the effect of homogenization pressure (P) was more significant than that of homogenization cycle number (N). The value of the rate constant k decreased with the increase of sludge total solid content. The specific energy consumption increased with the increment of sludge disintegration efficiency. Lower specific energy consumption was required for higher total solid content sludge. | Yuxuan Zhang Panyue Zhang panyue_zhang@bjfu.edu.cn Boqiang Ma Hao Wu Sheng Zhang Xin Xu | 2012 | Journal of Environmental Sciences2012，24，5： | 6 |
| 5 | Calcium silicate bioactive ceramics induce osteogenesis through oncostatin M显示文摘Immune reactions are a key factor in determining the destiny of bone substitute materials after implantation.Macrophages,the most vital factor in the immune response affecting implants,are critical in bone formation,as well as bone biomaterial-mediated bone repair.Therefore,it is critical to design materials with osteoimmunomodulatory properties to reduce host-to-material inflammatory responses by inducing macrophage polarization.Our previous study showed that calcium silicate(CS)bioceramics could significantly promote osteogenesis.Herein,we further investigated the effects of CS on the behavior of macrophages and how macrophages regulated osteogenesis.Under CS extract stimulation,the macrophage phenotype was converted to the M2 extreme.Stimulation by a macrophage-conditioned medium that was pretreated by CS extracts resulted in a significant enhancement of osteogenic differentiation of bone marrow mesenchymal stem cells(BMSCs),indicating the important role of macrophage polarization in biomaterial-induced osteogenesis.Mechanistically,oncostatin M(OSM)in the macrophage-conditioned medium promoted osteogenic differentiation of BMSCs through the ERK1/2 and JAK3 pathways.This in vivo study further demonstrated that CS bioceramics could stimulate osteogenesis better thanβ-TCP implants by accelerating new bone formation at defective sites in the femur.These findings improve our understanding of immune modulation of CS bioactive ceramics and facilitate strategies to improve the in vitro osteogenesis capability of bone substitute materials. | Panyu Zhou Demeng Xia Zhexin Ni Tianle Ou Yang Wang Hongyue Zhang Lixia Mao Kaili Lin Shuogui Xu Jiaqiang Liu | 2021 | Bioactive Materials2021，6，3： | 5 |

| 7 | Mechanical activation of spike fosters SARS-CoV-2 viral infection显示文摘The outbreak of SARS-CoV-2(SARS2)has caused a global COVID-19 pandemic.The spike protein of SARS2(SARS2-S)recognizes host receptors,including ACE2,to initiate viral entry in a complex biomechanical environment.Here,we reveal that tensile force,generated by bending of the host cell membrane,strengthens spike recognition of ACE2 and accelerates the detachment of spike’s S1 subunit from the S2 subunit to rapidly prime the viral fusion machinery.Mechanistically,such mechano-activation is fulfilled by force-induced opening and rotation of spike’s receptor-binding domain to prolong the bond lifetime of spike/ACE2 binding,up to 4 times longer than that of SARS-S binding with ACE2 under 10 pN force application,and subsequently by force-accelerated S1/S2 detachment which is up to~103 times faster than that in the no-force condition.Interestingly,the SARS2-S D614G mutant,a more infectious variant,shows 3-time stronger force-dependent ACE2 binding and 35-time faster force-induced S1/S2 detachment.We also reveal that an anti-S1/S2 non-RBD-blocking antibody that was derived from convalescent COVID-19 patients with potent neutralizing capability can reduce S1/S2 detachment by 3×106 times under force.Our study sheds light on the mechano-chemistry of spike activation and on developing a non-RBD-blocking but S1/S2-locking therapeutic strategy to prevent SARS2 invasion. | Wei Hu Yong Zhang Panyu Fei Tongtong Zhang Danmei Yao Yufei Gao Jia Liu Hui Chen Qiao Lu Tenny Mudianto Xinrui Zhang Chuxuan Xiao Yang Ye Qiming Sun Jing Zhang Qi Xie Pei-Hui Wang Jun Wang Zhenhai Li Jizhong Lou Wei Chen | 2021 | Cell Research2021，31，10： | 2 |

| 9 | Use of donor-specific red blood cell transfusions for patients undergoing liver transplantation during the COVID-19 pandemic显示文摘Background:Increased risks have been found for patients undergoing liver transplantation due to the blood supply shortage following the ongoing coronavirus disease 2019(COVID-19)pandemic.Hence,exploring a method to alleviate this dilemma is urgent.This phase I,nonrandomized,prospective trial aimed to evaluate the safety and feasibility of using donor-specific red blood cell transfusion(DRBCT)as an urgent measurement to alleviate the blood supply shortage in deceased donor liver transplantation(DDLT).Methods:The outcomes of 26 patients who received DRBCT and 37 patients in the control group who only received 3rd party packed red blood cells(pRBCs)transfusion between May 2020 and January 2021 were compared.Results:Patients receiving DRBCT did not develop transfusion-related complications,and the incidence of postoperative infection was similar to that in the control group(23.1%vs.18.9%,P=0.688).Because the patients received the red blood cells from organ donors,the median volume of intraoperative allogeneic red blood cell transfusion from blood bank was 4.0 U(IQR 1.1-8.0 U)in the DRBCT group,which is significantly lower than that(7.5 U,IQR 4.0-10.0 U)in the control group(P=0.018).The peak aspartate aminotransferase(AST)level was significantly lower in the DRBCT group than in the control group(P=0.008)and so were the AST levels in the first two days after the operation(P=0.006 and P=0.033).Conclusions:DRBCT is a safe and effective procedure to lower the need for blood supply and is associated with a reduction in AST levels after transplantation.DRBCT is beneficial to patients receiving life-saving transplantation without sufficient blood supply during the COVID-19 pandemic. | Tao Lv Xi Xu Jiulin Song Yifei Tan Li Jiang Jian Yang Diao He Lingxiang Kong Weiyi Zhang Panyu Chen Qiwen Xiang Tao Zhu Hong Wu Tianfu Wen Jiayin Yang | 2021 | Hepatobiliary Surgery and Nutrition2021，10，4： | 2 |

| 15 | Enhancement of ultrasonic disintegration of sewage sludge by aeration显示文摘Sonication is an effective way for sludge disintegration,which can significantly improve the efficiency of anaerobic digestion to reduce and recycle use of sludge.But high energy consumption limits the wide application of sonication.In order to improve ultrasonic sludge disintegration efficiency and reduce energy consumption,aeration was introduced.Results showed that sludge disintegration efficiency was improved significantly by combining aeration with ultrasound.The aeration flow rate,gas bubble size,ultrasonic density and aeration timing had impacts on sludge disintegration efficiency.Aeration that used in later stage of ultrasonic irradiation with low aeration flow rate,small gas bubbles significantly improved ultrasonic disintegration sludge efficiency.At the optimal conditions of 0.4 W/m L ultrasonic irradiation density,30 m L/min of aeration flow rate,5 min of aeration in later stage and small gas bubbles,ultrasonic sludge disintegration efficiency was increased by 45% and one third of ultrasonic energy was saved.This approach will greatly benefit the application of ultrasonic sludge disintegration and strongly promote the treatment and recycle of wastewater sludge. | He Zhao Panyue Zhang Guangming Zhang Rong Cheng | 2016 | Journal of Environmental Sciences2016，28，4： | 1 |
