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 effects of SPME fiber. This review introduces the preparation methods and applications of different kinds of carbon-based material coatings on fibers. In addition, directions for future research on carbon material composites are discussed. -
Electrochemical determination of chloramphenicol using a glassy carbon electrode modified with dendrite-like Fe₃O₄ nanoparticles

a glassy carbon electrode (GCE). The Fe3O4/GCE was utilized for sensing chloramphenicol (CAP) by cyclic voltammetry and square wave voltammetry. A reduction peak of CAP at the Fe3O4/GCE was observed at 0.62 V, whereas the uncoated GCE exhibited a very small response compared to that of the Fe3O4/GCE. The electrocatalytic ability of Fe3O4 was mainly attributed to the formation of Fe(VI) during the anodic scan, and its reduction to Fe(III) on the cathodic scan facilitated the sensing of CAP. The... -
Cellulose-based carbon fibers prepared using electron-beam stabilization

measured. The structure of the cellulose fibers was determined to have changed to hemicellulose and cross-linked cellulose as a result of the E-beam stabilization. The hemicellulose decreased the initial decomposition temperature, and the cross-linked bonds increased the carbonization yield of the cellulose fibers. Increasing the absorbed E-beam dose to 1500 kGy increased the carbonization yield of the cellulose-based carbon fiber by 27.5% upon exposure compared to untreated cellulose fibers. -
한반도 출토 인골의 황 안정동위원소를 통해 본 선사시대 사람들의 이주와 식단 연구
한국고고학회 한국고고학보 2018, 제 109집 2 40-65 (26 pages)
최근에 국내에서도 고고학적 유적에서 출토된 인골과 동물 뼈를 이용한 고식단 연구를 위해서 안정동위원소 분석이 시행되고 있다. 현재까지 대부분의 연구는 탄소와 질소 안정동위원소를 이용한 선사시대 생업활동의 복원에 초점을 맞춰 진행되고 있다. 탄소와 질소 안정동위원소와 더불어 황 안정동위원소도 고식단의 복원에 유용할 뿐만 아니라 탄소와 질소 안정동위원소에서 확인할 수 없는 선사시대 인간과 동물의 이주의 양상을 도출할 수 있는 유용한 연구방법이다. 본 연구에서는 새롭게 주목받고 있는 연구방법인 황... -

본 연구에서는 완주 덕동, 전주 유상리, 순창 동촌, 영광 월평리 등 호남 지역 조선시대 유적에서 출토 된 인골 34개체에 대해 탄소와 질소 안정동위원소 분석을 실시하여 조선시대 식생활의 구체적인 양상을 밝히고, 나아가 지역, 성별, 연령, 신분, 그리고 병리적 징후의 유무에 따라 안정동위원소 값에 차이가 있는지를 살펴봄으로써 사회경제적 요소에 따라 식생활에 차별이 있었는지를 논하고자 한다. 탄소와 질소 안정동위원소 분석 결과를 살펴보면, 완주 덕동 유적 δ13C= -19.2±0.6‱, δ15N= 11.3±0.6‱ (n=7),... -

Clavibacter michiganensis subsp. michiganesis (Cmm) is a quarantine-worthy pest in México. The implementation and validation of new technologies is necessary to reduce the time for bacterial detection in laboratory conditions and Raman spectroscopy is an ambitious technology that has all of the features needed to characterize and identify bacteria. Under controlled conditions a contagion process was induced with Cmm, the disease epidemiology was monitored. Micro-Raman spectroscopy (532 nm... -
Postharvest Disease Control of Colletotrichum gloeosporioides and Penicillium expansum on Stored Apples by Gamma Irradiation Combined with Fumigation
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 5호 10 460-468 (9 pages)
To study the control of postharvest decay caused by Colletotrichum gloeosporioides and Penicillium expansum, gamma irradiation alone or in combination with fumigation was evaluated to extend the shelf life of apples in South Korea. An irradiation dose of 2.0 kGy resulted in the maximum inhibition of C. gloeosporioides and P. expansum spore germination. The gamma irradiation dose required to reduce the spore germination by 90% was 0.22 and 0.35 kGy for C. gloeosporioides and P. expansum,...
