This study evaluated high water absorbency and constantly phosphorus release properties of two novel hybrid hydrogel materials as potential hydrogel fertilizers.In this article, the hybrid hydrogel materials——polybasic organic acid activating phosphate rock powder/PAA hydrogel fertilizers (Polybasic organic acid activating PRP-PAA-HF) were synthesized via aqueous solution polymerization,using N,N(c)-methylenebisacrylamide (MBA) as a cross-linker, ammonium persulfate (APS) as an initiator, citric acid and oxalic acid as polybasic organic acids.

白藜芦醇是一种天然植物抗毒素,具有多种潜在的应用价值,但由于其水溶性差、光稳定性弱,应用受到了极大限制.本文以小分子甘氨酸为连接臂将亲水分子聚乙二醇(PEG)与白藜芦醇进行化学交联.研究表明聚乙二醇改性后白藜芦醇的溶解度较原料药提高近100倍.此外,我们还发现改性后白藜芦醇,挺高了原料的光稳定性(图1)和延长了其抗氧化作用时间(图2).
通过反溶剂沉淀法和喷雾干燥法,制得平均粒径为330 nm的比卡鲁胺/乳糖纳米分散体,可在前2.5 min内溶出62.5%,并在120 min内基本全部溶解.虽然乳糖使药物溶解速率提高,但理论原因仍不清楚.因此,使用分子动力学模拟和对接计算相结合的方法进一步研究比卡鲁胺与辅料之间的相互作用.能量分析表明,比卡鲁胺与乳糖间主要为库仑作用,并强于与其他辅料间的相互作用.结构分析表明,比卡鲁胺/乳糖具有最
多壁碳纳米管具有优异的电学、力学和光学性能,但是在实际的应用过程中极易缠结,极大的限制了其优异性能的发挥.本文采用十八胺对多壁碳纳米管进行了表面修饰,并采用透射电镜电子显微镜(TEM)对其在常见脂类介质中的分散性能进行了表征,并通过沉降实验对所得的多壁碳纳米管在各类脂类介质中的稳定性进行了考查.

莫特绝緣体材料拥有优异的光学和电学性能.在发生半导体-金属相变(莫特相变)时,其红外光的透过率和电阻值发生显著改变,这种特性使其在许多领域都有广泛的应用前景.比如VO2在室温附近发生相变,可以作为热致变色涂层材料、光存储材料、光电开关器件和节能用智能窗材料等等.而相变温度较高的Ti2O3则可以用作高温智能窗、热存储功能材料等等.
本研究使用二氧化鈦/雲母及氮化硼為初始材料,分別經由機械混合及球化技術製備複合粉體.並以亞麻仁油製備乳液,經紫外光-近紅外線分光光度儀及防曬係數測試儀分析,對光學與防曬特性(防曬係數SPF、與臨界波長(Critical wavelength))進行探討,結果顯示,球型化之複合粉體經由粒度分析,其中位徑為(8.8um),相較於奈米二氧化鈦(~20nm)在光學特性上,有較優異的吸收强度.防曬特性方面,
