| 1 | Removal of heavy metals using waste eggshell显示文摘由再使用的蛋壳的有毒的重金属的移动能力被学习。作为为从废物蛋壳的再使用的材料的准备的一个预告的处理过程,锻烧在压碎弄干的废物蛋壳以后为 2 h 在 800 ° C 在炉子被执行。在蛋壳的锻烧前后的锻烧行为,质、量的元素的信息,矿物质类型和表面特征被热 gravimetric 检验分析(TGA ) , X 光检查荧光(XRF ) , X 光检查衍射(XRD ) 和扫描电子显微镜学(SEM ) 分别地。在锻烧以后,主要无机的作文作为 Ca 被识别(石灰, 99.63%) 并且 K, P 和 Sr 作为次要的部件被识别。当锻烧的蛋壳在包含重金属的合成废水的处理被使用时, Cd 以及在 Cr 的 99% 移动上面的完全的移动在 10 min 以后被观察。尽管自然蛋壳有 Cd 和 Cr 的一些移动能力,完全的移动没由于相当更慢的移动率甚至在 60 min 以后被完成。与 Cd 和 Cr 相对照,然而, Pb 的有效移动与自然蛋壳而非锻烧的蛋壳被观察。从在真实 electroplating 废水的处理的锻烧的蛋壳的申请,锻烧的蛋壳显示出重金属离子的一个有希望的移动能力以及在强壮的酸的废水的处理有一个好中立化能力。 | PARK Heung Jai JEONG Seong Wook YANG Jae Kyu KIM Boo Gil LEE Seung Mok | 2007 | Journal of Environmental Sciences2007，19，12： | 6 |
| 2 | Efficient photovoltaic effect in graphene/h-BN/silicon heterostructure self-powered photodetector显示文摘Graphene(Gr)/Si-based optoelectronic devices have attracted a lot of academic attention due to the simpler fabrication processes,low costs,and higher performance of their two-dimensional(2D)/three-dimensional(3D)hybrid interfaces in Schottky junction that promotes electron-hole separation.However,due to the built-in potential of Gr/Si as a photodetector,the Iph/Idark ratio is often hindered near zero-bias at relatively low illumination intensity.This is a major drawback in self-powered photodetectors.In this study,we have demonstrated a self-powered van der Waals heterostructure photodetector in the visible range using a Gr/hexagonal boron nitride(h-BN)/Si structure and clarified that the thin h-BN insertion can engineer asymmetric carrier transport and avoid interlayer coupling at the interface.The dark current was able to be suppressed by inserting an h-BN insulator layer,while maintaining the photocurrent with minimal decrease at near zero-bias.As a result,the normalized photocurrent-to-dark ratio(NPDR)is improved more than 104 times.Also,both Iph/Idark ratio and detectivity,increase by more than 104 times at−0.03 V drain voltage.The proposed Gr/h-BN/Si heterostructure is able to contribute to the introduction of next-generation photodetectors and photovoltaic devices based on graphene or silicon. | Ui Yeon Won Boo Heung Lee Young Rae Kim Won Tae Kang Ilmin Lee Ji Eun Kim Young Hee Lee Woo Jong Yu | 2021 | Nano Research2021，14，6： | 2 |
| 3 | Primary intestinal lymphangiectasia with generalized warts显示文摘Primary intestinal lymphangiectasia(PIL) is a rare protein-losing enteropathy with lymphatic leakage into the small intestine. Dilated lymphatics in the small intestinal wall and mesentery are observed in this disease. Laboratory tests of PIL patients revealed hypoalbuminemia, lymphocytopenia, hypogammaglobulinemia and increased stool α-1 antitrypsin clearance. Cell-mediated immunodeficiency is also present in PIL patients because of loss of lymphocytes. As a result, the patients are vulnerable to chronic viral infection and lymphoma. However, cases of PIL with chronic viral infection, such as human papilloma virus-induced warts, are rarely reported. We report a rare case of PIL with generalized warts in a 36-year-old male patient. PIL was diagnosed by capsule endoscopy and colonoscopic biopsy with histological tissue confirmation. Generalized warts were observed on the head, chest, abdomen, back, anus, and upper and lower extremities, including the hands and feet of the patient. | Soon Jae Lee Hyun Joo Song Sun-Jin Boo Soo-Young Na Heung Up Kim Chang Lim Hyun | 2015 | World Journal of Gastroenterology2015，21，27： | 1 |
| 4 | 新电动力转向系统的模型开发和控制方法显示文摘本文研究了一个新柱型电动力转向(EPS-TT)系统。这种EPS-TT系统的显著特点是采用光隔离转矩传感器测量转向器转矩,它的辅助转矩控制方法是采用一个单向马达和两个离合器。因而它不需要一个复杂的马达驱动系统,该系统在作反向转动时要耗费大量的电能。为估算EPS-TT开发了一个完整的转向系统模型和一个简化了的模型。一个完整的车辆模型用来研究车辆的响应。为控制EPS-TT系统设计了线圈载体控制法和比例积分微分控制算法。分析了加于系列不同正弦输入和结果性能。结果表明用ESP-TT系统所达到的性能和常规的ESP系统通过的频率范围相似。整个转向系统模型结果和简化了的模型结果相似但车辆的响应稍稍不同。该线圈载体控制提供了好的性能不影响车辆的稳定性和可控性。 | Jeonghoon Song Kwangsuck Boo Heung Seobkim Jongil Lee Sunyoung Hong 刘青(译) | 2006 | 传动技术2006，20，4： | 0 |
