The review of approaches to knowledge management system studies

Abstract: Purpose – This paper reviews the current literature of knowledge management systems (KMS) studies in organizations. The authors systematically review the literature according to the principle of innovation studies approach, i.e. variance and process approaches. The purpose of this paper is to identify the current state of KMS studies in organizations. By doing this, the way is paved for the authors to find the research gaps, which would facilatively suggest the direction for future research. The authors hope that this review will be regarded as a source for those who share mutual interests in KMS research and could stimulate further research being conducted in the area with different approaches in the future.Design/methodology/approach – Journal articles published within the period 2003‐2013 were collected. The articles were sourced mainly from Emerald, Science Direct, IEEE, MIS Quarterly, as well as some other academic databases. The search was conducted using such keywords as “knowledge management syste...

Effect of Synthesis Parameters on the Formation of Zeolitic Imidazolate Framework 8 (ZIF-8) Nanoparticles for CO2 Adsorption

Abstract: Zeolitic imidazole frameworks-8 (ZIF-8) is a subclass of metal-organic frameworks (MOFs) with the transition metal cations (Zn2+) linked by imidazolate anions forming tetrahedral frameworks in zeolite-like topologies. This article reports on the synthesis of ZIF-8 nanoparticles by varying the synthesis parameters at room temperature. The crystallization duration, molar ratios, and pH of the mixture solution were varied in order to study the effects of these parameters on the formation of ZIF-8 nanoparticles. The structural and morphology transformation of the resultant particles were characterized using x-ray diffraction, field emission scanning electron microscopy, and Brunauer–Emmett–Teller (BET) surface analysis. The CO2 adsorption characteristics of ZIF-8 nanoparticles were tested using CO2 physisorption analysis. Mature structural evolution was observed for ZIF-8 synthesized at 60 and 1440 min, but insufficient crystallization was found for ZIF-8 synthesized at 5 min. Meanwhile, ZIF-8 nanoparticles s...
