        This study aims to examine domestic research trends on technoparks and to explore future research directions in this field. For this purpose, 493 articles were collected from academic journal sites, covering the period from 1997, when the pilot technoparks were designated, to 2022. To avoid duplication of identical titles and content, theses and conference papers were excluded. Only articles registered or candidate-registered in the Korea Citation Index (KCI) were selected. After reviewing the research topics and content, a total of 74 papers were used for the final analysis. The data analysis involved descriptive analyses of the research period, research areas, research methods, research subjects, and research topics. Furthermore, a word cloud text analysis was conducted using 305 keywords related to technoparks. This study is significant as the first comprehensive analysis of research trends on technoparks and aims to provide meaningful foundational data to explore future directions for research and innovation policy related to technoparks.

        In this study, cellulose nanoplates (CNPs) were fabricated using cellulose nanocrystals obtained from commercial microcrystalline cellulose (MCC). Their pyrolysis behavior and the characteristics of the product carbonaceous materials were investigated. CNPs showed a relatively high char yield when compared with MCC due to sulfate functional groups introduced during the manufacturing process. In addition, pyrolyzed CNPs (CCNPs) showed more effective chemical activation behavior compared with MCC-induced carbonaceous materials. The activated CCNPs exhibited a microporous carbon structure with a high surface area of 1310.6 m2/g and numerous oxygen heteroatoms. The results of this study show the effects of morphology and the surface properties of cellulose-based nanomaterials on pyrolysis and the activation process.
