TL;DR: This work utilizes blockchain technology, which serves as a secure tamper-proof distributed ledger to IoT devices, to assign a unique ID for each individual device and record them into the blockchain, so that they can authenticate each other without a central authority.
Abstract: The existing identity authentication of IoT devices mostly depends on an intermediary institution, i.e., a CA server, which suffers from the single-point-failure attack. Even worse, the critical data of authenticated devices can be tampered by inner attacks without being identified. To address these issues, we utilize blockchain technology, which serves as a secure tamper-proof distributed ledger to IoT devices. In the proposed method, we assign a unique ID for each individual device and record them into the blockchain, so that they can authenticate each other without a central authority. We also design a data protection mechanism by hashing significant data (i.e. firmware) into the blockchain where any state changes of the data can be detected immediately. Finally, we implement a prototype based on an open source blockchain platform Hyperledger Fabric to verify the proposed system.

TL;DR: A study of online reviews to measure how product attributes impact customer satisfaction found that customers who buy cheap products should be treated differently from purchasers of expensive items because the relevance of design features on their satisfaction is different.

TL;DR: In this paper, the absolute elastic wave band gaps in three-dimensional systems consisting of steel inclusions embedded in plastic matrix were investigated and the configurations formed by inserting an additional steel object (either a sphere of different size or a cube) into each unit cell of a simple cubic structure with spherical inclusions were investigated.

TL;DR: The mesoporous TiO2 nanofibers with high specific surface areas and abundant surface hydroxyl groups are prepared using an electrospinning strategy combined with a subsequent calcination process, followed by a solvothermal treatment, exhibiting excellent photocatalytic performance on CO2 reduction into hydrocarbon fuels.
Abstract: Photocatalytic reduction of CO2 into renewable hydrocarbon fuels using semiconductor photocatalysts is considered as a potential solution to the energy deficiency and greenhouse effect. In this work, mesoporous TiO2 nanofibers with high specific surface areas and abundant surface hydroxyl groups are prepared using an electrospinning strategy combined with a subsequent calcination process, followed by a solvothermal treatment. The solvothermally treated mesoporous TiO2 nanofibers exhibit excellent photocatalytic performance on CO2 reduction into hydrocarbon fuels. The significantly improved photocatalytic activity can be attributed to the enhanced CO2 adsorption capacity and the improved charge separation after solvothermal treatment. The highest activity is achieved for the sample with a 2-h solvothermal treatment, showing 6- and 25-fold higher CH4 production rate than those of TiO2 nanofibers without solvothermal treatment and P25, respectively. This work may also provide a prototype for studying the effect of solvothermal treatment on the structure and photocatalytic activity of semiconductor photocatalysts.
