聚合物前驱体成本高、碳化后处理工艺中有机溶剂的应用,以及能源消耗等问题,限制了碳纤维在日常生活中的应用。采用离心力纺丝技术及在酸蒸气中脱水的方法制备非织造纳米纤维垫,并采用低温碳化工艺(t<800℃)制备多功能碳纳米纤维。这种方法可以制备微孔与中孔的多孔非织造碳纤维织物或纱线。纤维的直径可在几百纳米到几微米之间变化。热物理和微观结构表征表明,化学和热处理过程中的碳化形成了石墨。所制备的纤维表现出较高的导电性和比表面积,以及良好的热稳定性、疏水性和亲油性。

Although data for temporal spring river ice breakup are available for a number of Arctic rivers, there is a paucity of information related to the type of breakup. The Arctic Climate Impact Assessment (ACIA) of 2005 predicted a transition from mechanical to thermal spring breakup of ice cover on arctic rivers, with this shift being greatest in exclusively Arctic watersheds where observed warming is most pronounced. We describe a rare instance of an entirely Arctic river with limited but well documented historical and recent data regarding the type of breakup. Time-series ground imagery of spring breakup from 1966, 1975, 1978, 2009, 2010 and 2012, incombination with interviews of local inhabitants, documents a shift from predominantly mechanical to predominantly thermal breakup after spring 1978 and by spring 2009 within the context of a locally and regionally warming Arctic. The resultant shift from predominantly mechanical to predominantly thermal breakup is predicted to result in significant changes to water, sediment, nutrient and organic carbon fluxes, as well as riparian ecology and human activities.

yle="text-align:justify;"> Chronic liver disease (CLD) refers to a structural and functional change of the liver, which modifies the pharmacokinetics of multiple drugs, including hypoglycemic agents. This alteration depends on the severity degree of the liver disease, clinical characteristics of the patient, and comorbidities presence such as kidney disease and drug biochemistry. Insulin is considered a safe therapeutic strategy in patients with CLD, however, for many oral hypoglycemic agents, its use and dose adjustment will depend on the Child-Pugh score, based on the risk of hypoglycemia in this type of patient.

To solve a problem, three things are necessary： awareness, means, and will. The 2015 COP21 Paris accord was a masterful, perhaps even world-saving, diplomatic advance toward making the world aware of climate change. Some of that success may have been because publications from the IPCC and the National Academy of Science were made available, on line, as prepublication offerings, in order to be widely viewed before the Paris Climate Conference. This provided diplomats and nego- tiators with the latest information about climate change, its nearness in time, its consequences, and how well current mitigation technologies can succeed. Whatever the rea- sons, the ParAs Climate Conference, was a success. leaders of 195 nations agreed that climate change is a real and present danger to life as is known to all. This important understanding was accomplished despite the presentation of well established scientific facts which, without very diplomatic handling, could easily have evoked over- whelming political opposition to an agreement and thus another COP failure. In this paper, the fact that how some scientific truths, written specifically to be overlooked, were presented in order to prepare COP21 participants for the conference is explained. Besides, the effectiveness and efficiency of currently favored mitigation policies, the extent of ongoing progress to better ones, and finally, how a new appreciation of climate change consequences can strengthen the will of nation states and industries to work toward solutions are evaluated.
