Molecular Sieves
Zeolite molecular sieves are widely used in gas separation, but this application often requires discriminating differences as little as 0.1 Å. Molecular sieving with such size selectivity demands zeolites with highly tunable pore diameters. In article number 2105398, Michal Mazur, Hae Sung Cho, Changbum Jo, and co‐workers report the development of a versatile method for tuning zeolite...
Zeolite molecular sieves are widely used in gas separation and shape‐selective catalysis, but these applications often require discriminating differences as little as 0.1 Å. Molecular sieving with such size selectivity demands zeolites with highly tunable pore diameters and adsorption properties, which are technically challenging to prepare. Nevertheless, it is shown that a wide range of organic functional...
We consider the downlink of a wireless cellular network which consists of one Macro Base Station (MBS), multiple relays and User Equipments (UEs). In this scenario, we propose relay clustering algorithms to address the problem of inter-cluster interference. In each cluster, we adopt a time-division relaying scheme to avoid intra-cluster interference, but the inter-cluster interference still remains...
We consider the downlink of a realistic cellular network composed of multiple clusters, each of which includes multiple relays and a destination terminal. In this scenario, the interference among the clusters is a critical issue, affecting the end-to-end performance of the system significantly. Considering the inter-cluster interference, we propose optimal and suboptimal relay selection schemes to...
Mitigating inter-cell interference has become more crucial than before because there is a growing number of base stations (BSs) being placed into the network as a solution to increase the network capacity. To deal with the problem, cache-induced CoMP was recently proposed. It is based on caching a portion of media files, and taking benefits of sharing payload data (CoMP joint processing), but without...
For extended cell coverage and green communication, various small-cell networks, such as femtocells and picocells, are applied to cellular networks. This leads to the reduction of shadow areas and an increase of spectral efficiency with higher cell-edge capacity. Due to increasing heterogeneity, however, small cells cause co-tier and cross-tier interferences which are the critical issue that aggravates...
