研究Cr元素对新开发的ECO-7175合金热变形行为的影响。采用Gleeble热模拟机对含Cr和不含Cr的ECO-7175样品进行热压(温度为350~500℃、应变速率为0.001~1 s^(−1)),研究合金的本构方程、加工图和显微组织演变。对变形激活能的分析表明,含Cr合金中速率控制变形机制由Al的自扩散(或Al中Mg的扩散)逐渐转变为Al中Cr的扩散,且Zener−Hollomon参数减小。对含Cr合金的加工图的分析表明,动态再结晶(DRX)区局限于高温和低应变速率下的变形,且随着应变的增加而扩大。另一方面,发现Al的自扩散(或Al中Mg的扩散)是无铬合金在所有加工条件下热变形过程中唯一的速率控制机制,其DRX区与塑性应变无关。

This study shows that the mechanical strength of the composite of Fe matrix and titanium carbide(Ti C)ceramic particles is significantly enhanced with addition of molybdenum(Mo) atoms. Ti C reinforced Fe(Fe-0.2C-7Mn) composites with and without Mo were fabricated by a liquid pressing infiltration(LPI)process and the effect of Mo on interfacial properties of TiC–Fe composite was investigated using atomic probe tomography(APT) analysis, molecular dynamics(MD) simulations, first-principle density functional theory(DFT), and thermodynamic calculations. First, DFT calculations showed that total energies of the Mo-doped Ti C–Fe superlattices strongly depend on the position of Mo defects, and are minimized when the Mo atom is located at the TiC/Fe interface, supporting the probable formation of MoC-like interphase at the TiC/Fe interface region. Then, APT analysis confirmed the DFT predictions by finding that about6.5 wt.% Mo is incorporated in the Ti C–Fe(Mo) composite and that sub-micrometer thick(Ti,Mo)C interphase is indeed formed near the interface. The MD simulations show that Mo atoms migrate to the Mo-free TiC–Fe interface at elevated temperatures and the mechanical strength of the interface is considerably enhanced, which is in good agreement with experimental observations.

Evaluation of the performance of a soft X-ray charger for the bipolar charging of nanoparticles

引用

Particuology 2015年第1期13卷 165-169页

作者： Young Hun Yoon Choonkeun bong Dae Seong kim Department of Integrated Environmental Systems Pyeongtaek University GreenSolus Co. Global Frontier Center for Multiscale Energy Systems Seoul National University

The use of soft X-rays in a neutralizer represents an alternative technique that could replace conventional radioactive sources. In this study, we evaluated the charging characteristics of a soft X-ray aerosol neu- tralizer. In addition, the results from the evaluation of the soft X-ray charger were compared with results obtained using a neutralizer incorporating an 241 Am radioactive source. The tandem differential mobility analyzer technique was used previously to determine the size-dependent positive, negative, and neutral charge fractions of a soft X-ray neutralizer. This technique was used to show that the neutral fractions obtained using the soft X-ray charger agreed well with the predictions of bipolar diffusion charging the- ory, and that the soft X-ray charger could be used as a neutralizer for a scanning mobility particle sizer system.

Tumor response assessment by the single-lesion measurement per organ in small cell lung cancer

Chinese Journal of Cancer Research 2016年第2期28卷 161-167页

作者： Soong goo Jung Jung Han kim Hyeong Su kim Kyoung Ju kim Ik Yang Department of Internal Medicine Kangnam Sacred-Heart HospitalHallym University Medical CenterHallym University College of MedicineSeoulRepublic of Korea Department of Radiation Oncology Kangnam Sacred-Heart HospitalHallym University Medical CenterHallym University College of MedicineSeoulRepublic of Korea Department of Radiology Kangnam Sacred-Heart HospitalHallym University Medical CenterHallym University College of MedicineSeoulRepublic of Korea

Background： The criterion of two target lesions per organ in the Response Evaluation Criteria in Solid Tumors （RECIST） version I. 1 is an arbitrary one, being supported by no objective evidence. The optimal number of target lesions per organ still needs to be investigated. We compared tumor responses using the RECIST 1.1 （measuring two target lesions per organ） and modified RECIST I. 1 （measuring the single largest lesion in each organ） in patients with small cell lung cancer （SCLC）. Methods： We reviewed medical records of patients with SCLC who received first-line treatment between January 2004 and December 2014 and compared tumor responses according to the two criteria using computed tomography. Results： There were a total of 34 patients who had at least two target lesions in any organ according to the RECIST 1.1 during the study period. The differences in the percentage changes of the sum of tumor measurements between RECIST 1.1 and modified RECIST 1.1 were all within 13%. Seven patients showed complete response and fourteen showed partial response according to the RECIST I.I. The overall response rate was 61.8%. When assessing with the modified RECIST 1.1 instead of the RECIST 1.1, tumor responses showed perfect concordance between the two criteria （k= 1.0）. Conclusions： The modified RECIST 1.I showed perfect agreement with the original RECIST 1.I in the assessment of tumor response of SCLC. Our result suggests that it may be enough to measure the single largest target lesion per organ for evaluating tumor response.
