| 1 | Enhanced efficiency in lead-free bismuth iodide with post treatment based on a hole-conductor-free perovskite solar cell显示文摘Despite the excellent merits of lead perovskite solar cells,their instability and toxicity still present a bottleneck for practical applications.Bismuth perovskite has emerged as a candidate for photovoltaic (PV) applications,because it not only has a low toxicity but is also stable in air.However,the power conversion efficiency (PCE) remains an unsolved problem.We performed band gap tuning experiments to improve the efficiency.The absorption of ABi3I10 structure films was extended within the visible region,and the optical band gap was decreased considerably compared to that for Cs3Bi2I9.Furthermore,we explained the correlation between the structure and the optical properties via a first-principles study.A device employing CsBi3I10 as a photoactive layer exhibits a PCE of 1.51% and an excellent ambient stability over 30 days. | Jongmoon Shin Maengsuk Kim Sujeong Jung Chang Su Kim Jucheol Park Aeran Song Kwun-Bum Chung Sung-Ho Jin Jun Hee Lee Myungkwan Song | 2018 | Nano Research2018，11，12： | 4 |
| 4 | Sarcopenia:Clinical implications in ovarian cancer,diagnosis,etiology,and management显示文摘Sarcopenia,loss of skeletal muscle and function,is a common condition among the elderly and is known to cause adverse health outcomes and increased risk of morbidity and mortality.This progressive and generalized disorder imposes a considerable socioeconomic burden.Sarcopenia is observed commonly in cancer patients.As Asia is one of the fastest aging regions in the world,it is clear that incidences of both sarcopenia and ovarian cancer will increase together in Asian countries.Ovarian cancer patients are vulnerable to develop sarcopenia during the treatment course and progress of disease,and a considerable number of patients with ovarian cancer seems to have physical inactivity and sarcopenia already at the time of diagnosis.Therefore,management of sarcopenia should be conducted together in parallel with ovarian cancer treatment and surveillance.Thus,in this article,we will review the clinical importance of sarcopenia in the aspect of ovarian cancer.Definition of sarcopenia,diagnosis,etiology,and intervention will be also introduced. | Aeran Seol Se Ik Kim Yong Sang Song | 2020 | Sports Medicine and Health Science2020，2，4： | 1 |
