Heterostructures in two-dimensional colloidal metal chalcogenides:Synthetic fundamentals and applications

引用

Nano Research 2019年第8期12卷 1750-1769页

作者： Yuho Min Eunmi Im Geon-Tae Hwang jong-woo Kim Cheol-woo Ahn jong-Jin Choi Byung-Dong hahn Joon-Hwan Choi woon-Ha Yoon Dong-Soo Park Dong Choon Hyun Geon Dae Moon Functional Ceramics Department Powder & Ceramics DivisionKorea Institute of Materials Science (KIMS)ChangwonGyeongnam51508Republic of Korea Department of Polymer Science and Engineering Kyungpook National UniversityDaegu41566Republic of Korea Dongrtam Regional Division Korea Institute of Industrial TechnologyBusan46938Republic of Korea

As a new class of two-dimensional materials, two-dimensional (2D) heterostructures constructed from metal chalcogenides (MCs) have been gaining tremendous attention due to their unprecedented physical and chemical phenomena, mainly originated from their distinct structural features such as composition, architecture type, spatial arrangement of each component, crystal structure, exposed facet and interface, dimensionality in their heterostructures. Towards the realization of practical applications, synthetic approaches need a rational design with a variety of architecture types including laterally-combined, vertically-aligned, and conformally-coated 2D MC heterostructures. Among various synthetic routes, solution-based synthesis is thought of as an alternative to fabrication through high-cost setups since it can control those structural features in a cheap fashion. This review presents recent progress on solution-based synthesis to produce various 2D MC heterostructures with a focus on the synthetic fundamentals in terms of thermodynamic and kinetic aspects related to the growth mechanism. Four different synthetic approaches are reviewed: seeded growth, cation exchange reaction, colloidal atomic layer deposition, direct synthesis including one-step process and modified electrochemical method. We also provide some representative applications of 2D MC heterostructures and their hybrid composites in various fields including optoelectronics, thermoelectrics, catalysis, and battery. Finally, we offer an insight into challenges and future directions in a synthetic improvement of 2D MC heterostructures.

Smart Proactive Caching Scheme for Fast Authenticated Handoff in Wireless LAN

引用

Journal of Computer Science & Technology 2007年第3期22卷 476-480页

Handoff in IEEE 802.11 requires the repeated authentication and key exchange procedures, which will make the provision of seamless services in wireless LAN more difficult. To reduce the overhead, the proactive caching schemes have been proposed. However, they require too many control packets delivering the security context information to neighbor access points. Our contribution＇ is made in two-fold： one is a significant decrease in the number of control packets for proactive caching and the other is a superior cache replacement algorithm.

Extraperitoneal Rectal Laceration Secondary to Blunt Trauma： Successful Transanal Endoscopic Repair with Hemoclips

引用

Chinese Medical Journal 2017年第19期130卷 2384-2385页

作者： Koo-Yong hahn Soon-Young Ko woo-Surng Lee Yong-Hun Kim 'Department of Surgery School of Medicine Konkuk University Konkuk University Chungju Hospital Chungju-si Chungbuk Korea Department of Internal Medicine School of Medicine Konkuk University Konkuk University Chungju Hospital Chungju-si Chungbuk Korea Department of Thoracic and Cardiovascular Surgery School of Medicine Konkuk University Konkuk University Chungju Hospital Chungju-si Chungbuk Korea

Rectal injuries are caused by a variety of causes, such as stab wounds, gunshot injuries, blunt trauma, and foreign bodies. In particular, extraperitoneal rectal injury secondary to blunt trauma is very rare in the civilian setting and usually seen in association with comminuted fractures of the pelvis or sacrum and evidence of intraperitoneal injury.[1] The management of extraperitoneal rectal injury is treated either surgically or conservatively depending on the level and extent of the injury.[2] Currently, management of less severe extraperitoneal rectal injury is not standardized, but primary closure of the wound should be performed whenever possible. Therefore, we present a patient with a laceration of the midrectum secondary to blunt trauma who was successfully treated with endoscopic hemoclipping.

Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy

Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically.

Gallbladder lymphangioma:A case report and review of the literature

World Journal of Gastroenterology 2007年第2期13卷 320-323页

作者： Jwa-Kyung Kim Kyo-Sang Yoo Joon Ho Moon Kwang Hyuk Park Yong woo Chung Kyoung Oh Kim Cheol Hee Park Taeho hahn Sang Hoon Park jong Hyeok Kim Jang Yeong Jeon Min Jung Kim Kwang Seon Min Department of Pathology Hallym University College of Medicine Anyang Korea Choong Kee Park Department of Gastroenterology and Hepatology Hallym University College of Medicine Anyang Korea Department of Surgery Hallym University College of Medicine Anyang Korea Department of Diagnostic Radiology Hallym University College of Medicine Anyang Korea

Lymphangiomas are rare, benign tumors of the lymphatic system, usually present in children aged 5 years and younger. Because they are asymptomatic until the mass enlarges to cause symptoms, most lymphangiomas are diagnosed at adulthood incidentally. We experienced a case of a 60-year-old man diagnosed with a cystic lymphangioma of the gallbladder, which was successfully resected without any complication. Magnetic resonance imaging and magnetic resonance cholangiopancreatography were very helpful for the diagnosis of the cystic lesion around the gallbladder as were ultrasonography and computed tomography scan. These showed a multi-lobulated cystic mass with intact cystic duct and bile duct in the gallbladder fossa. The patient underwent an open cholecystectomy and the histological findings were consistent with a cystic lymphangioma of the gallbladder. We here report the case of cystic lymphangioma of the gallbladder with a review of the literature.
