| 1 | Hybridisation of perovskite nanocrystals with organic molecules for highly efficient liquid scintillators显示文摘Compared with solid scintillators,liquid scintillators have limited capability in dosimetry and radiography due to their relatively low light yields.Here,we report a new generation of highly efficient and low-cost liquid scintillators constructed by surface hybridisation of colloidal metal halide perovskite CsPbA_(3)(A:Cl,Br,I)nanocrystals(NCs)with organic molecules(2,5-diphenyloxazole).The hybrid liquid scintillators,compared to state-of-the-art CsI and Gd_(2)O_(2)S,demonstrate markedly highly competitive radioluminescence quantum yields under X-ray irradiation typically employed in diagnosis and treatment.Experimental and theoretical analyses suggest that the enhanced quantum yield is associated with X-ray photon-induced charge transfer from the organic molecules to the NCs.High-resolution X-ray imaging is demonstrated using a hybrid CsPbBr_(3) NC-based liquid scintillator.The novel X-ray scintillation mechanism in our hybrid scintillators could be extended to enhance the quantum yield of various types of scintillators,enabling low-dose radiation detection in various fields,including fundamental science and imaging. | Sangeun Cho Sungwoo Kim Jongmin Kim Yongcheol Jo Ilhwan Ryu Seongsu Hong Jae-Joon Lee SeungNam Cha Eun BiNam Sang Uck Lee Sam Kyu Noh Hyungsang Kim Jungwon Kwak Hyunsik Im | 2020 | Light(Science & Applications)2020，9，1： | 4 |

| 8 | In vivo analysis of post-joint-preserving surgery fracture of 3D-printed Ti-6Al-4V implant to treat bone cancer显示文摘Cancer growth in the bone due to its random shape disables bone strength and thus changes its capacity to support body weight or muscles,which can crucially affect the quality of human life in terms of normal walking or daily activities.For successful patient recovery,it is necessary to remove the cancer-affected minimal bone area and quickly replace it with a biocompatible metal implant within less than 2 weeks.An electron beam-melted Ti-6Al-4V implant was designed and applied in a patient to preserve the natural knee joint close to the bone tumor.The developed implant fits the bone defect well,and the independent ambulatory function of the natural knee joint was restored in the patient within six weeks after surgery.A delayed fracture occurred six months after the successful replacement of cancer-affected bone with Ti-6Al-4V implant at the proximal meshed junction of the implant because of a minor downward slip.Microstructural,mechanical,and computational analyses were conducted for the fractured area to find the main reason for the delayed fracture.Our findings pertaining to the mechanical and material investigation can help realize the safe implantation of the three-dimensionally printed titanium implant to preserve the natural joints of patients with massive bone defects of the extremities. | Jong Woong Park Ye Chan Shin Hyun Guy Kang Sangeun Park Eunhyeok Seo Hyokyung Sung Im Doo Jung | 2021 | Bio-Design and Manufacturing2021，4，4： | 1 |
