| 1 | Synthesis of Porous NiO Nanocrystals with Controllable Surface Area and Their Application as Supercapacitor Electrodes显示文摘We report a facile way to grow various porous NiO nanostructures including nanoslices,nanoplates,and nanocolumns,which show a structure-dependence in their specific charge capacitances.The formation of controllable porosity is due to the dehydration and re-crystallization of β-Ni(OH)_(2) nanoplates synthesized by a hydrothermal process.Thermogravimetric analysis shows that the decomposition temperature of the β-Ni(OH)_(2) nanostructures is related to their morphology.In electrochemical tests,the porous NiO nanostructures show stable cycling performance with retention of specific capacitance over 1000 cycles.Interestingly,the formation of nanocolumns by the stacking of β-Ni(OH)_(2) nanoslices/plates favors the creation of small pores in the NiO nanocrystals obtained after annealing,and the surface area is over five times larger than that of NiO nanoslices and nanoplates.Consequently,the specific capacitance of the porous NiO nanocolumns(390 F/g)is significantly higher than that of the nanoslices(176 F/g)or nanoplates(285 F/g)at a discharge current of 5 A/g.This approach provides a clear illustration of the process-structure-property relationship in nanocrystal synthesis and potentially offers strategies to enhance the performance of supercapacitor electrodes. | Xiaojun Zhang Wenhui Shi Jixin Zhu Weiyun Zhao Jan Ma Subodh Mhaisalkar Tuti Lim Maria Yanhui Yang Hua Zhang Huey Hoon Hng Qingyu Yan | 2010 | Nano Research2010，3，9： | 24 |
| 2 | Risk factors of electrocoagulation syndrome after esophageal endoscopic submucosal dissection显示文摘AIM To investigate post endoscopic submucosal dissection electrocoagulation syndrome(PEECS) of the esophagus.METHODS We analyzed 55 consecutive cases with esophageal endoscopic submucosal dissection for superficial esophageal squamous neoplasms at a tertiary referral hospital in South Korea. Esophageal PEECS was defined as 'mild' meeting one of the following criteria without any obvious perforation: fever(≥ 37.8 ℃), leukocytosis(> 10800 cells/μl), or regional chest pain more than 5/10 points as rated on a numeric pain intensity scale. The grade of PEECS was determined as 'severe' when meet two or more of above criteria.RESULTS We included 51 cases without obvious complications in the analysis. The incidence of mild and severe esophageal PEECS was 47.1% and 17.6%, respectively. Risk factor analysis revealed that resected area, procedure time, and muscle layer exposure were significantly associated with PEECS. In multivariate analysis, a resected area larger than 6.0 cm^2(OR = 4.995, 95%CI: 1.110-22.489, P = 0.036) and muscle layer exposure(OR = 5.661, 95%CI: 1.422-22.534, P = 0.014) were independent predictors of esophageal PEECS. All patients with PEECS had favorable outcomes with conservative management approaches, such as intravenous hydration or antibiotics.CONCLUSION Clinicians should consider the possibility of esophageal PEECS when the resected area exceeds 6.0 cm^2 or when the muscle layer exposure is noted. | Dae Won Ma Young Hoon Youn Da Hyun Jung Jae Jun Park Jie-Hyun Kim Hyojin Park | 2018 | World Journal of Gastroenterology2018，24，10： | 3 |
| 3 | Approaching 18%efficiency of ternary organic photovoltaics with wide bandgap polymer donor and well compatible Y6:Y6-1O as acceptor显示文摘A series of ternary organic photovoltaics(OPVs)are fabricated with one wide bandgap polymer D18-Cl as donor,and well compatible Y6 and Y6-1O as acceptor.The open-circuit-voltage(V_(OC))of ternary OPVs is monotonously increased along with the incorporation of Y6-1O,indicating that the alloy state should be formed between Y6 and Y6-1O due to their excellent compatibility.The energy loss can be minimized by incorporating Y6-1 O,leading to the V_(OC)improvement of ternary OPVs.By finely adjusting the Y6-1O content,a power conversion efficiency of 17.91%is achieved in the optimal ternary OPVs with 30 wt%Y6-1O in acceptors,resulting from synchronously improved short-circuit-current density(JSC)of 25.87 mA cm^(-2),fill factor(FF)of 76.92%and V_(OC)of 0.900 V in comparison with those of D18-Cl:Y6 binary OPVs.The JSC and FF improvement of ternary OPVs should be ascribed to comprehensively optimal photon harvesting,exciton dissociation and charge transport in ternary active layers.The more efficient charge separation and transport process in ternary active layers can be confirmed by the magnetophotocurrent and impedance spectroscopy experimental results,respectively.This work provides new insight into constructing highly efficient ternary OPVs with well compatible Y6 and its derivative as acceptor. | Xiaoling Ma Anping Zeng Jinhua Gao Zhenghao Hu Chunyu Xu Jae Hoon Son Sang Young Jeong Caixia Zhang Mengyang Li Kai Wang He Yan Zaifei Ma Yongsheng Wang Han Young Woo Fujun Zhang | 2021 | National Science Review2021，8，8： | 3 |
| 4 | Alterations of Gefitinib Pharmacokinetics by Co-administration of Herbal Medications in Rats显示文摘Objective: To evaluate the potential pharmacokinetic interactions of the anticancer agent gefitinib(Iressa?) and the oriental medications Guipi Decoction(归脾汤, GPD, Guibi-tang in Korean) and Bawu Decoction(八物汤, BWD, Palmul-tang in Korean). Methods: Methylcellulose(MC, control), GPD(1,200 mg/kg), or BWD(6,000 mg/kg) was orally administered to rats either as a single dose or multiple doses prior to gefitinib administration. To examine the effects of a single dose of the herbal medicines, gefitinib(10 mg/kg) was orally administered after 5 min or 1 h of MC or the herbal medicine pretreatments. To examine the effects of the multiple doses of the herbal medicines, gefitinib(10 mg/kg) was orally administered following 7 consecutive days of the administration of MC or each herbal medicine. The plasma concentrations of gefitinib were determined with liquid chromatography-tandem mass spectrometry assay. The plasma concentration-time profiles of gefitinib were analyzed with a noncompartmental analysis. Results: Gefitinib was rapidly absorbed and showed a monoexponential decline with an elimination half-life of 3.7–4.1 h. The pharmacokinetics of gefitinib was not affected by GPD pretreatment. However, a significantly lower maximum plasma concentration(Cmax, P<0.05) and area under the curve(P<0.05), and a delayed time to reach Cmax(Tmax, P<0.01) were observed in both single-and multipledose BWD-pretreated rats compared with the control rats. Conclusions: BWD and not GPD might delay and interfere with gefitinib absorption. Further evaluations of the clinical significance of these findings are needed. | Kwon-Yeon Weon Min Gi Kim Soyoung Shin Tae Hwan Kim Sang Hoon Joo Eunsook Ma Seok Won Jeong Sun Dong Yoo Yu Seok Youn Beom Soo Shin | 2018 | Chinese Journal of Integrative Medicine2018，24，6： | 2 |
