다양한 종류의 지방산 아실 체인으로 치환된 Cellulose mixed esters(CME)는 재생 가능한 bio-based 폴리머이 다. 셀룰로오스 에스터는 생분해성 고분자로써, 분해되지 않는 석유계 플라스틱을 대체할 미래 고분자 소재이다. 본 연구에서는 개질 실험에 앞서 alpha 셀룰로오스를 40℃의 증류수에 2시간동안 activation하였다. Water-activated 셀룰로 오스와, 다양한 불포화 지방산, 무수 아세트산을 120℃의 lithium chloride/N,N-dimethylacetamide (LiCl/DMAc)용매에서 5시간동안 반응시켜 CME를 합성했다. 세척과 감압을 반복한 후, TGA, FT-IR, 1H-NMR과 FE-SEM를 통해 특성을 관찰하였고, water activation이 셀룰로오스의 수산기 치환에 미치는 영향에 대하여 조사하였다. Cellulose mixed esters (CME), substituted by various fatty acyl chains, are renewable bio-based polyesters. It has lots of potential due to the biodegradable property. In this study, Alpha cellulose was activated for 2h at 40℃ in deionized water prior to synthesis. Homogeneous esterification of CME was accomplished with water-activated alpha cellulose, various saturated fatty acids and acetic anhydride in lithium chloride/N, N-dimethylacetamide (LiCl/DMAc) medium. CME was obtained after 5 hr at 120℃. The filtrated products were characterized using TGA, FT-IR, 1H-NMR and FE-SEM, and the influence of water activation on the total degree of substitution was investigated.

Purpose: Reactivation of hepatitis B virus (HBV) replication after hepatic resection might be a significant risk factor for prognosis in patients with chronic hepatitis B. The purpose of the present study was to investigate the changing pattern of serum HBV DNA titer after hepatic resection and to assess the incidence of reactivation of HBV replication. Methods: Among HBV-positive patients who underwent hepatic resection for hepatocellular carcinoma, thirty-six patients with preoperative serum HBV DNA titer ≥3 log10copies/mL were enrolled. Serum DNA titers were examined before the operation, on the second and seventh postoperative days, and one month after the operation. Results: The serum DNA titer decreased on the second postoperative day (p=0.078). The DNA level, however, had substantially returned to preoperative values by the seventh postoperative day (p<0.001). For most patients, the postoperative DNA titer reached its zenith on the seventh postoperative day or one month after the operation. The zenith level was higher (by 0.49±0.25 log10copies/mL) than preoperative levels although this difference just missed significance (p=0.068). Although postoperative reactivation of HBV replication emerged in 6 patients, only one of those patients developed postoperative hepatitis. Overall, four patients developed postoperative hepatitis and all of them had high postoperative HBV DNA levels (over 6 log10copies/mL). Conclusion: Although serum HBV DNA titers tended to increase postoperatively, routine antiviral therapy might be unnecessary because of the low incidence of postoperative hepatitis. High postoperative DNA levels, however, might be a risk factor for hepatitis, and postoperative follow-up of serum HBV DNA levels might be necessary in HBV-positive patients with hepatic resection.

김해리 ( Hae Ri Kim ),남병욱 ( Byeong Uk Nam ),김승범 ( Seung Beom Kim ) 한국공업화학회 2012 응용화학 Vol.16 No.1

Currently, there is increasing interest in using biodegradable and renewable materials for disposable applications as an alternative of some conventional petroleum plastics. Cellulose ester, particularly preferable for a liquid crystal display device, is prepared from the esterification of cellulose derived from abundant plant. Poly(lactic acid) (PLA) is a promising synthetic biopolymer derived from agricultural feedstock, but it has poor thermal and mechanical properties. In this work, Poly(lactic acid) (PLA) and Cellulose acetate butyrate (CAB) were melt blended using twin screw extruder in order to improve properties of bio-based polymer and to expand applications. The phase morphology of PLA/CAB alloys was investigated by Scanning Electronic Microscopy (SEM). The compatibility of alloys was analyzed by Fourier-Transformation Infrared (FT-IR) and Dynamic Mechanical Analyzer (DMA).

<P><B>Abstract</B></P> <P>Bacterial pathogens of water origin have potential public threats thus suggesting the need of developing efficient and sustainable water disinfection strategies from waterborne pathogens. We set out to synthesize different controlled morphologies of graphitic carbon nitride (g-C<SUB>3</SUB>N<SUB>4</SUB>) polymer, evaluate their comparative effects on the generation of reactive oxygen species (ROS), and investigate potential applications in water purification systems. Characterization of the synthesized microstructures of g-C<SUB>3</SUB>N<SUB>4</SUB>, such as melamine-cyanuric acid (MCA)-based rosette-type, rod-type, 2D hexagonal, and 3D cubic mesoporous silica was accomplished using Fourier transform infrared (FT-IR), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), X-ray diffractometry (XRD), and transmission electron microscopy (TEM). The microbial inhibitory potential of 2D g-C<SUB>3</SUB>N<SUB>4</SUB> photocatalyst against waterborne <I>Escherichia coli</I>, <I>Staphylococcus aureus</I>, and <I>Salmonella typhimurium</I> was evaluated based on the effective activity of 2D g-C<SUB>3</SUB>N<SUB>4</SUB> upon visible light excitations. The microbicidal efficiency of 2D g-C<SUB>3</SUB>N<SUB>4</SUB> was evident within 30 min of visible light exposure via direct interaction, while other microstructures of g-C<SUB>3</SUB>N<SUB>4</SUB> demonstrated only slight antimicrobial effects after 120 min, with insufficient ROS generation. The antimicrobial and ROS-generating effects of 2D g-C<SUB>3</SUB>N<SUB>4</SUB> depended on the type and surface area of the synthesized 2D g-C<SUB>3</SUB>N<SUB>4</SUB> material. Considering its availability and excellent disinfection activity, 2D g-C<SUB>3</SUB>N<SUB>4</SUB> obtained from simple and convenient facile synthesis is a promising solar-driven photocatalyst for clearing microbial contamination from water.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Waterborne pathogenic bacteria pose significant health risks to the public. </LI> <LI> We synthesized different morphologies of graphitic carbon nitride (g-C<SUB>3</SUB>N<SUB>4</SUB>) polymer. </LI> <LI> Synthesized microstructures of g-C<SUB>3</SUB>N<SUB>4</SUB> had potential effect on ROS generation. </LI> <LI> 2D hexagonal g-C<SUB>3</SUB>N<SUB>4</SUB> exhibited significant antimicrobial potential. </LI> <LI> 2D g-C<SUB>3</SUB>N<SUB>4</SUB> had photocatalytic inactivation efficiency in a water purifying system. </LI> </UL> </P>
