, such as low reduction potential as cathode materials or high reduction potential as anode materials. Here, the influence of chemical functionalities that are capable of either electron donating or electron withdrawing groups on the reduction potential and charge-discharge performance of anthraquinone (AQ) based system is studied. The cyclic voltammetry results show that the introduction of two -OH......
Attaining the Steady State of the Nitriding Potential after a Change of NH3 Atmosphere Flow Rate during the Gas Nitriding Process Piotr Wach1,Jerzy Michalski1,Nabil Tarfa2,Jan Tacikowski1,Tomasz... is characterized by the following parameters:temperature and time, type and composition of incoming atmosphere, as well as the set value of the nitriding potential. In the case of an atmosphere composed of raw......
, the potential functions for quasicrystal and its approximant have many local minimums due to its particular topology. There are mainly two kinds of potentials for quasicrystal. One is the potentials based on regular ones represented by Dzugutov potential and LJG potential. They are generally applied in the simulation of monatomic and diatomic systems. Dzugutov potential is a short-term interaction which......
Biosorption potential of cerium ions using Spirulina biomassDavid Sadovsky1,2,Asher Brenner11. Unit of Environmental Engineering, Faculty of Engineering Sciences, Ben-Gurion University of the Negev摘 要:Two types of cyanobacteria of the genus Arthrospira(commonly known as Spirulina) were tested for biosorption of cerium(III) ions from aqueous solutions......

析型煤的成型机理.通过实验室型煤成型试验优选出三种型煤粘结剂:腐殖酸,淀粉,钠基膨润土.理论分析,扫描电镜检测和Zeta电位测量结果表明:腐殖酸,淀粉和钠基膨润土这三种粘结剂都可使煤粒充分地结合,可使型煤有较好的冷强度,热强度,热稳定性.腐殖酸,淀粉作为有机粘结剂,粘结性和耐水性优于钠基膨润土,但热稳定性相对较差,而钠基膨润土为无机粘结剂,来源广泛,价格优惠,热稳定性和热强度较好,但可燃性差,增加型煤灰分,降低型煤的发热量,故三种粘结剂复配,同时可提高型煤的冷强度,热强度,热稳定性,易满足工业型煤使用要求;对比三种粘结剂的扫描电镜图可发现加入淀粉时,煤粒之间可形成更多的形状各异且分布均匀的结晶体和凝胶体,型块的强度更大;从测试出的原煤及不同粘结剂型煤的Zeta电位的大小来看,型煤煤粒表面的Zeta电位也会影响型煤的的强度大小,煤粒表面Zeta电位的绝对值越小,静电斥力越小,型煤强度就越高......
