| 1 | Prognostic and incremental value of computed tomography-based radiomics from tumor and nodal regions in esophageal squamous cell carcinoma显示文摘Objective:This study aimed to evaluate the prognostic value of preoperative radiomics and establish an integrated model for esophageal squamous cell cancer(ESCC).Methods:A total of 931 patients were retrospectively enrolled in this study(training cohort,n=624;validation cohort,n=307).Radiomics features were obtained by contrast-enhanced computed tomography(CT)before esophagectomy.A radiomics index was set based on features of tumor and reginal lymph nodes by using the least absolute shrinkage and selection operator(LASSO)Cox regression.Prognostic nomogram was built based on radiomics index and other independent risk factors.The prognostic value was assessed by using Harrell’s concordance index,time-dependent receiver operating characteristics and Kaplan-Meier curves.Results:Twelve radiomic features from tumor and lymph node regions were identified to build a radiomics index,which was significantly associated with overall survival(OS)in both training cohort and validation cohort.The radiomics index was highly correlated with clinical tumor-node-metastasis(cTNM)and pathologic TNM(pTNM)stages,but it demonstrated a better prognostic value compared with cTNM stage and was almost comparable with pTNM stage.Multivariable Cox regression showed that the radiomics index was an independent prognostic factor.An integrated model was constructed based on gender,preoperative serum sodium concentration,pTNM and the radiomics index for clinical usefulness.The integrated model demonstrated discriminatory ability better compared with the traditional clinical-pathologic model and pTNM alone,indicating incremental value for prognosis.Conclusions:CT-based radiomics for primary tumor and reginal lymph nodes was sufficient in predicting OS for patients with ESCC.The integrated model demonstrated incremental value for prognosis and was robust for clinical applications. | Bangrong Cao Kun Mi Wei Dai Tong Liu Tianpeng Xie Qiang Li Jinyi Lang Yongtao Han Lin Peng Qifeng Wang | 2022 | Chinese Journal of Cancer Research2022，34，2： | 3 |
| 2 | Understanding the role of tungsten on Pt/CeO_(2)for vinyl chloride catalytic combustion显示文摘Spherical CeO_(2)synthesized by the hydrothermal process was used as support to prepare Pt/WO_(3)/CeO_(2),and the effects of tungsten(W)contents on activity,stability and polychlorinated by-products were investigated to understand the role of W for vinyl chloride(VC)catalytic oxidation.The introduction of12 wt%W to Pt/CeO_(2)(P12 WC)exhibits the highest catalytic activity with 90%conversion of VC at 250℃,meanwhile the stability improves and the polychlorinated by-products in the tail gas significantly decrease due to the removal of dissociated Cl species in the formation of HCl.The beneficial effects of W on Pt/CeO_(2)are closely related to the chemical state of Pt,redox and surface acid sites distribution.The doped W not only makes Pt disperse evenly on the support with the high valence,but also weakens the interaction between Pt and CeO_(2)by the formation of Pt-O-W and Pt-O-W-O-Ce species,which facilitates oxygen mobility.In addition,the modification of W species also significantly increases the surface acidity amount and changes the distribution of acid sites. | Qifeng Zhang Zhengbo Zhou Tian Fang Han Gu Yanglong Guo Wangcheng Zhan Yun Guo Li Wang | 2022 | Journal of Rare Earths2022，40，9： | 2 |
| 3 | Efficient degradation of organic pollutants by S-NaTaO_(3)/biochar under visible light and the photocatalytic performance of a permonosulfate-based dual-effect catalytic system显示文摘Removing large concentrations of organic pollutants from water efficiently and quickly under visible light is essential to developing photocatalytic technology and improving solar energy efficiency.This study used a simple hydrothermal method to prepare a non-metallic,S-doped NaTaO_(3)(S-NTO) photocatalyst,which was then loaded onto biochar (BC) to form a S-NTO/BC composite photocatalyst.After uniform loading onto BC,the S-NTO particles transformed from cubic to spherical.The photogenerated electron-hole pair recombination probability of the composite photocatalyst was significantly lower than those of the NTO particles.The light absorption range of the catalyst was effectively widened from 310 nm UV region to visible region.In addition,a dual-effect catalytic system was constructed by introducing peroxymonosulfate (PMS) into the environment of the pollution to be degraded.The Rhodamine B,Methyl Orange,Acid Orange 7,tetracycline,and ciprofloxacin degradation efficiency at 40 mg/L reached 99.6%,99.2%,84.5%,67.1%,and 70.7%,respectively,after irradiation by a 40 W lamps for 90 min.The high-efficiency visible-light catalytic activity of the dual-effect catalytic system was attributed to doping with non-metallic sulfur and loading of catalysts onto BC.The development of this dual-effect catalytic system provides new ideas for quickly and efficiently solving the problem of high-concentration organic pollution in aqueous environments,rationally and fully utilizing solar energy,and expanding the application of photocatalytic technology to practice. | Yuehui Tai Jinlong Sun Haoran Tian Fuyue Liu Boyu Han Wei Fu Zhangpei Liu Xiuye Yang Qifeng Liu | 2023 | Journal of Environmental Sciences2023，，3： | 1 |
| 4 | Progress of all-perovskite tandem solar cells:the role of narrow-bandgap absorbers显示文摘Perovskite solar cells(PSCs)have gained increasing attention due to their excellent photovoltaic performance,achieving certified power conversion efficiency(PCE)of 25.2%.To further enhance PCE and break the Shockley-Queisser limit of the single junction PSCs,great efforts have been made in tandem solar cells based on perovskite,including perovskite/Si,and perovskite/perovskite(all-perovskite).Among them,all-perovskite tandem solar cells exhibit unique advantages of both lowcost fabrication and high efficiency.They have advanced rapidly in these years,due to the realization of stable and efficient narrow-bandgap perovskites.In this work,we review the development of monolithic all-perovskite tandem solar cells and highlight the critical role of narrow-bandgap perovskites in recent progress of all-perovskite solar cells.We also propose our perspective of future directions on this subject. | Xinhui Luo Tianhao Wu Yanbo Wang Xuesong Lin Hongzhen Su Qifeng Han Liyuan Han | 2021 | Science China Chemistry2021，64，2： | 1 |
| 5 | A new panel containing specific spermatogenesis markers to identify spermatogenic cells in nonobstructive azoospermia patients显示文摘Infertility is a severe problem that affects 10%-15% of couples worldwide, among which male infertility is a factor in ~50% of the cases [1]. Azoospermia, which is defined as the absence of sperm in at least two ejaculates, can be divided into two types: obstructive azoospermia (OA) and non-OA (NOA)[1]. OA patients have normal spermatogenesis and mature sperm in testes and can father a biological child through testicular sperm retrieval and intracytoplasmic sperm injection (ICSI)[2]. By contrast, NOA patients usually have various degrees of spermatogenesis impairment and can be faced with complicated assisted reproductive technology (ART) strategies to father a biological child [2]. The precise diagnosis of spermatogenesis in NOA patients is crucial for clinical decision making regarding ART. | Xinxi Zhao Yiqin Wang Meng Ma Wei Zhang Jiqiang Si Wei Wang Zhen Lin Gang Han Charlie Degui Chen Minghan Tong Yanping Kuang Qifeng Lyu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，6： | 1 |
| 6 | Stable perovskite solar cells with 23.12% efficiency and area over 1 cm^(2) by an all-in-one strategy显示文摘To realize the commercialization of perovskite solar cells(PSCs), it is required to overcome the remaining challenges in device enlargement and operational stability. Here, we report an all-in-one strategy by integrating the oxidation of hole-transport material(HTM) with the formation of the passivation layer, which simultaneously solved the stability issues caused by HTM oxidation and realized the uniform defects in passivation over a large area. The resulting devices achieved a certified PCE of23.12% on average with an aperture area of 1.04 cm^(2) and are reproducible with high operational stability because of the exclusion of air exposure, hygroscopic Li-TFSI, and the lithium-based wastes, maintaining ca. 90% of their initial PCEs after operation at the maximum power point under continuous 1 sun illumination for 1,600 h. Our strategy simplifies the fabrication process of PSCs, which is compatible with commercial-scale methods, offering facile access to efficient and stable large-area PSCs. | Hongzhen Su Xuesong Lin Yanbo Wang Xiao Liu Zhenzhen Qin Qiwei Shi Qifeng Han Yiqiang Zhang Liyuan Han | 2022 | Science China Chemistry2022，65，7： | 0 |
| 7 | Spectral and Photosynthetic Characteristics of Cotton under Chemical-controlled Topping Technology显示文摘[Objective] The paper was to study the effect of chemical-controlled topping technology on spectral and photosynthetic characteristics of cotton. [Method] Two row spacing configurations and four topping treatments were set in the experiment field, and the spectral and photosynthetic characteristics of cotton under different configurations and topping treatments were analyzed. [Result] There was no significant difference in spectral reflectance of cotton leaves and canopy among all treatments(T1-T8) before topping. After topping, the spectral reflectance of cotton leaves showed little difference in visible light band, but significant differences in near-infrared light band under two row spacing configurations(T2-T4, T6-T8).And in near-infrared band, compared with CK(T1, T5), the reflectance increased and then decreased under close planting with equal row spacing configurations(T2-T4) and narrow row dense planting configurations(T6-T8). However, the change of cotton canopy reflectance in short infrared bands increased first and then decreased under close planting with equal row spacing configuration, and increased constantly under narrow row dense planting configuration. The photosynthetic capacity of leaves increased, and the net photosynthetic rate(A), stomatal conductance(GH_(2O)),transpirationrate(E) and intercellular CO_(2) concentration(Ci) significantly increased by controlling the top with chemicals, and differences were ob-served between two configurations. After topping treatments, the leaf area of apical leaf increased, and chemical-controlled topping treatments had significant difference with the control. The apical cotton leaves were shrunk internally, and the plant height increased gradually by 7-15 cm;the number of fruit branches increased by 2-4, and the area of apical leaves decreased significantly in chemical-controlled topping treatments.[Conclusion] After topping with chemicals, the spectral characteristics of cotton change, the photosynthetic capacity of leaves is improved, and the growth of apical leaves and apex of cotton is inhibited. | Bing Chen Jing Wang Qifeng Wu Gang Wang Jing Zhao Huanyong Han Fangyong Wang | 2021 | Plant Diseases and Pests2021，12，3： | 0 |
