Sodium ion battery is a promising electrical energy storage system for sustainable energy storage applications due to the abundance of sodium resources and their low cost. In this communication, the electrochemical properties of sodium ion storage in reduced graphene oxide (RGO) were studied in an electrolyte consisting of 1 M NaClO4 in propylene carbonate (PC). The experimental results show th...

Lithium-rich Li(1.13)Ni(0.30)Mn(0.57)O2 has been functionally modified with fast Li(+)-ion conducting Li2SiO3via a facile and novel method, based on the reaction between Ni(0.35)Mn(0.65)C2O4·xH2O and Si(OC2H5)4. Due to the unique Li2SiO3 coating layer which greatly improves the Li(+) ion diffusion rate, Li2SiO3@Li(1.13)Ni(0.30)Mn(0.57)O2 exhibits outstanding rate capability, cycle stability and...

Lithium titanate (Li4Ti5O12 or LTO) is a promising negative electrodematerial of high-power lithium-ion batteries, due to its superior rate capability and excellent capacity retention. However, the specific capacity of LTO is less than one half of that of graphite electrode. In this work, we applied ultrathin oxide coating on LTO by the atomic layer deposition technique, aiming for increasing t...

Process capability indices such as Cp, Cpk, Cpu and Cpl are common metrics to evaluate and predict the performance of a process. Although higher process capability indices indicate higher process “quality”, but a high quality process does not necessarily guarantee the fewer rates of rejects. Therefore, a process capability index based on rate of rejects or real losses is more reliable and prope...

An implementation of both finite rate and equilibrium chemistry have been completed for the OVERFLOW code, a chimera capable, complex geometry flow code widely used to predict transonic flowfields. The implementation builds on the computational efficiency and geometric generality of the solver.

Recently much has been written about sustainability and greening and the issue is likely to continue to resurface on the agendas of decision makers. This paper addresses one aspect of the topic: that of sustainability and greening through information technology management. The authors review existing research and publications on the topic and conclude that while much research is available on me...

The present study discussed the issue of gender and career maturity which operated on Super‟s Theory of career development. The aim was to examine the effects of gender on career maturity among counseling students in a public university in Malaysia. The Career Maturity Inventory by Crites (1995) was utilized as the major instrument for the study. Seventy-six participants comprising 35 males and...

We study a novel aspect of a firm’s capital structure, namely the profile of its debt maturity dates. In a simple theoretical framework we show that the dispersion of debt maturities constitutes an important dimension of capital structure choice, driven by firm characteristics and debt rollover risk. Guided by these results we establish two main empirical results. First, using an exogenous shoc...
