采用自制的碱溶性聚酯/碳酸钙(COPET/CaCO_(3))母粒与聚酯(PET)母粒,经熔融纺丝实现对传统PET纤维的改性,结合单因子控制变量法优选碱酸处理制备COPET/CaCO_(3)/PET多孔纤维的最佳工艺参数,并对纤维性能进行测试与表征。结果表明,当NaOH质量分数为4%、HCL质量分数为3%时,纤维具有较好的表观形态和孔隙结构。在最优处理条件下,纤维内部含有较多分布均匀的孔隙,孔径主要集中分布在15~54nm。此时,纤维的断裂强度、线密度、比表面积和熔融温度分别为1.29cN/dtex、4.84dtex、5.5273m^(2)/g和253.85℃。

Despite remarkable advances in molecular and cell biology of acute myeloid leukemia(AML),AML patients still frequently relapse and have low 5-year overall survival(OS)rates.1 It is worth noting that a recent study from the registry or clinical trial compilation has reported an improvement in the OS of adult AML patients,especially those under 60 years of age.

褐煤作为一种低阶煤越来越引起人们重视,微生物转化褐煤制备高值化学品是利用褐煤的新技术手段,分离筛选可高效溶解转化褐煤的微生物是该技术的关键。从内蒙古东部平庄矿区褐煤中分离到一株具有较好溶解转化褐煤能力的内源真菌命名为HM-M1,经基因鉴定为草酸青霉菌(Peni⁃cillium oxalicum)。该菌株具有对褐煤环境适应性强和溶解转化效率高的优点,在液体培养基中28℃下溶煤处理20 d,对预处理褐煤溶解率达50.3%。同时对煤样进行了元素分析和工业分析,并利用SEM、FTIR对微生物溶解转化前后褐煤的结构进行分析。试验结果表明该菌株可在以褐煤为唯一营养源的条件下生长,并可将褐煤进一步溶解转化为黑色液体。经过硝酸氧化处理后褐煤中含氧量增加,同时硝酸处理可将褐煤中部分固定碳通过氧化断键转变为挥发份,进一步提高褐煤的微生物溶解转化率;SEM分析结果表明经草酸青霉菌HM-M1溶解转化后褐煤残渣呈腐蚀形状,褐煤结构变得疏松多孔,有较多的褐煤成分被溶解转化为液体流出。FTIR分析结果表明草酸青霉菌HM-M1主要对褐煤中含O和N基团如羰基、羧基、酰胺基、醚键等部位进行断键降解;对褐煤溶解转化液态产物进行GC-MS分析,得到10种浓度较高的溶解转化产物,包括苯甲酸、邻苯二甲酸酯类、苯并呋喃、萘类、菲类等,这些化合物均为应用价值较高的精细化工原料和医药合成中间体。本研究首次从褐煤中分离草酸青霉菌,并应用于褐煤的溶解转化制备高值化学品。

Room temperature ionic liquid [1-butyl-3-methylimidazolium]BF4 was prepared under microwave irradiation. Platinum （Pt） nanoparticles were synthesized in the ionic liquid with ethanol as reductant. The structure and morphology of the Pt nanoparticles were characterized by SEM, FTIR and TG-DTA. The results show that the mean diameter of the nanoparticles was about 10nm and the surface was modified with the room temperature ionic liquid. The catalytic property was evaluated by hydrogenation of benzaldehyde in ethanol and the conversion reached up to 80% under hydrogen pressure.

粉煤灰中氧化铝质量分数可达15%-40%,是制备氧化铝和氢氧化铝的很好资源。综述了近年来国内外从粉煤灰中提取氧化铝的制备工艺及进展,主要分为酸浸取法及烧结法。分别从各制备工艺的特点、优点及其存在的缺陷等方面进行简要的评述,并对其发展趋势进行了阐述。传统制备工艺不同程度地存在能量消耗高、产生二次污染、生产周期长、提取率不稳等不足。采用超声波、微波等新技术代替传统制备工艺中的煅烧、研磨和氟化物助溶等高耗能、高污染的技术将具有广阔的应用前景。
