가수분해반응에 대하여 높은 활성을 나타내었고 여러 차례의 재사용이 가능하였다. 광학순도가 높은 키랄 에폭사이드 생성물은 가수분해반응이 진행된 후에 촉매와 함께 유기용액상에서 취득되었다. 물에 용해되는 친수성의 1,2-디올은 키랄 살렌의 촉매작용에 의하여 가수분해됨으로써 생성되는데, 이들은 반응이 진행되는 동안 SBA-16 또는 NaY/SBA-16 실리카층을 통해 물층으로 확산되었다. 물은 막반응계에서 반응물이면서 동시에 용매로서 거동하였다. 연속흐름형의 막반응기를 적용함으로써, 고순도, 고수율의 광학이성체를... -

The binding specificities of various lectins, such as the Dolichos biflorus agglutinin (DBA), soybean agglutinin (SBA), and the Bandeiraea simplicifolia BS-1 (Isolectin B4), Triticum vulgaris (WGA), Arachis hypogaea (PNA), and Ulex europaeus (UEA-I) lectins, were studied in the vomeronasal organ of the horse. The microvilli of the vomeronasal sensory epithelium were positive for DBA, SBA, Isolectin B4, WGA, PNA, and UEA-I. The receptor cells showed intense reactivity for DBA and WGA. Lectins... -
Applications of carbon-based materials in solid phase micro-extraction: a review
Jian Guo, Soo-Jin Park, Long-Yue Meng, Xinghua Jin 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 2 10-17 (8 pages)
With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption... -
One-step synthesis of dual-transition metal substitution on ionic liquid based N-doped mesoporous carbon for oxygen reduction reaction
Ulziidelger Byambasuren, Yukwon Jeon, Dorjgotov Altansukh, Yunseong Ji, Yong-Gun Shul 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 8 53-64 (12 pages)
Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were... -
Proteomic and Phenotypic Analyses of a Putative Glycerol-3-Phosphate Dehydrogenase Required for Virulence in Acidovorax citrulli

Acidovorax citrulli (Ac) is the causal agent of bacterial fruit blotch (BFB) in watermelon, a disease that poses a serious threat to watermelon production. Because of the lack of resistant cultivars against BFB, virulence factors or mechanisms need to be elucidated to control the disease. Glycerol-3-phosphate dehydrogenase is the enzyme involved in glycerol production from glucose during glycolysis. In this study, we report the functions of a putative glycerol-3-phosphate dehydrogenase in Ac... -
‘글자’에 대한 인식의 변화와 문화 번역 -⌈훈민정음⌋(1446)과 ⌈글자의 혁명⌋(1947)을 바탕으로-
우리말학회 우리말연구 2011, 제29집 11 295-320 (26 pages)
이 연구는 역사의 전환기에 ‘글자‘의 변화를 시도한 대표적인 두 텍스트인 『훈민정음』(1446)과 『글자의 혁명』(1947)에 주목하고, 이 텍스 트에서 보여주는 ‘글자‘와 글자에 대한 인식에 대해 살펴보았다. 알려져 있다시피, 『훈민정음』은 창제 당시보다 20C에 들어와서 새롭게 조명받기 시작했다. 이 연구에서는 이러한 인식 변화의 바탕에 그 시대의 가치 기준이 작동된다는 것을 전제하고 그것의 구체적인 양상을 고찰하였다. 이를 위해 15세기의 훈민정음에 대한 인식과, 20세기의 훈민정음에 대 한 인식을 비교하였다....
