| 1 | 介孔载体嫁接的离子液体催化二氧化碳合成碳酸丙烯酯显示文摘将离子液体1-丙基(三乙氧基硅基)-3-甲基咪唑的氢氧化物([Smim]OH)分别嫁接到介孔SiO_2、MCM-41和SBA-15分子筛上制备了非均相嫁接型离子液体,用傅里叶变换红外光谱、N_2吸附、元素分析和热重分析等技术对3种非均相嫁接型离子液体进行了表征。在无溶剂、温和的条件下,以非均相嫁接型离子液体为催化剂,研究了环氧丙烷(PO)与CO_2环加成合成碳酸丙烯酯的反应。实验结果表明,3种非均相嫁接型离子液体均具有较好的催化性能,[Smim]OH/SiO_2的催化性能最好;在[Smim]OH/SiO_2 1.260 mmol、PO 70 mmol、CO_22 MPa、120℃、8 h的优化反应条件下,PO的转化率可达99.5%;[Smim]OH/SiO_2重复使用4次后仍能保持较高的催化性能。 | 张学兰 Abdullah S N Al-Arifi Taieb Aouak Zeid Abdullah Al-Othman 魏伟 孙予罕 | 2009 | 石油化工2009,38,12: | 8 |
| 2 | Fluid balance concepts in medicine:Principles and practice显示文摘The regulation of body fluid balance is a key concern in health and disease and comprises three concepts. The first concept pertains to the relationship between total body water(TBW) and total effective solute and is expressed in terms of the tonicity of the body fluids. Disturbances in tonicity are the main factor responsible for changes in cell volume, which can critically affect brain cell function and survival. Solutes distributed almost exclusively in the extracellular compartment(mainly sodium salts) and in the intracellular compartment(mainly potassium salts) contribute to tonicity, while solutes distributed in TBW have no effect on tonicity. The second body fluid balance concept relates to the regulation and measurement of abnormalities of sodium salt balance and extracellular volume. Estimation of extracellular volume is more complex and error prone than measurement of TBW. A key function of extracellular volume, which is defined as the effective arterial blood volume(EABV), is to ensure adequate perfusion of cells and organs. Other factors, including cardiac output, total and regional capacity of both arteries and veins, Starling forces in the capillaries, and gravity also affect the EABV. Collectively, these factors interact closely with extracellular volume and some of them undergo substantial changes in certain acute and chronic severe illnesses. Their changes result not only in extracellular volume expansion, but in the need for a larger extracellular volume compared with that of healthy individuals. Assessing extracellular volume in severe illness is challenging because the estimates of this volume by commonly used methods are prone to large errors in many illnesses. In addition, the optimal extracellular volume may vary from illness to illness, is only partially based on volume measurements by traditional methods, and has not been determined for each illness. Further research is needed to determine optimal extracellular volume levels in several illnesses. For these reasons, extracellular volume in severe illness merits a separate third concept of body fluid balance. | Maria-Eleni Roumelioti Robert H Glew Zeid J Khitan Helbert Rondon-Berrios Christos P Argyropoulos Deepak Malhotra Dominic S Raj Emmanuel I Agaba Mark Rohrscheib Glen H Murata Joseph I Shapiro Antonios H Tzamaloukas | 2018 | World Journal of Nephrology2018,7,1: | 3 |
| 3 | Hypertonicity:Clinical entities,manifestations and treatment显示文摘Hypertonicity causes severe clinical manifestations and is associated with mortality and severe short-term and longterm neurological sequelae. The main clinical syndromes of hypertonicity are hypernatremia and hyperglycemia.Hypernatremia results from relative excess of body sodium over body water. Loss of water in excess of intake,gain of sodium salts in excess of losses or a combination of the two are the main mechanisms of hypernatremia.Hypernatremia can be hypervolemic,euvolemic or hypovolemic. The management of hypernatremia addresses both a quantitative replacement of water and,if present,sodium deficit,and correction of the underlying pathophysiologic process that led to hypernatremia.Hypertonicity in hyperglycemia has two components,solute gain secondary to glucose accumulation in the extracellular compartment and water loss through hyperglycemic osmotic diuresis in excess of the losses of sodium and potassium. Differentiating between these two components of hypertonicity has major therapeutic implications because the first component will be reversed simply by normalization of serum glucose concentration while the second component will require hypotonic fluid replacement. An estimate of the magnitude of the relative water deficit secondary to osmotic diuresis is obtained by the corrected sodium concentration,which represents a calculated value of the serum sodium concentration that would result from reduction of the serum glucose concentration to a normal level. | Helbert Rondon-Berrios Christos Argyropoulos Todd S Ing Dominic S Raj Deepak Malhotra Emmanuel I Agaba Mark Rohrscheib Zeid J Khitan Glen H Murata Joseph I Shapiro Antonios H Tzamaloukas | 2017 | World Journal of Nephrology2017,6,1: | 2 |
