The solution-phase synthesis by chemical transformation from reactive templates has proved to be very effective in morphology-controlled synthesis of inorganic nanostructures. This review paper summarizes the recent progress in solution-phase synthesis of one-dimensional and hollow inorganic nanostructures via reactive templates, focusing on the approaches developed in our lab. The formation mechanisms based on reactive templates are discussed in depth to show the general concepts for the preparation processes. An outlook on the future development in this area is also presented.

Since the 18th National Congress of the Communist Party of China, the Party CentralCommittee has put innovation-driven development to a great importance, which is a trumpet for a battlefor innovation-driven educational reform and development. To realize the great rejuvenation of the Chinesenation is calling for educational innovation-driven development. Therefore, traditional system of educationshould be treated in both sides; education needs innovation but not outdated reform; there must be a sini-cized theoretical system of educational science to lead and guide.

Node synchronization is essential for the stability of the Bitcoin network. Critics have raised doubts about the ability of a new node to quickly and efficiently synchronize with the Bitcoin network and alleviate the storage pressure from existing full nodes to stockpile new data. Basic pruning and other techniques have been explored to address these concerns but have been insufficient to reduce node synchronization delay and effectively suppress the growth of synchronized data. In this study, we propose SnapshotPrune, a novel pruning and synchronization protocol that achieves fast node bootstrapping in the Bitcoin blockchain. Real Bitcoin historical data are leveraged to measure the synchronization time and monitor the network traffic during node bootstrapping. The protocol requires data downloads that are 99.70% less than Bitcoin Core, 81% less than CoinPrune, and 60% less than SnapshotSave, thereby saving 97.23% of download time. Findings show that the proposed design enhances the storage efficiency and reduces the node synchronization delay compared with existing techniques. We hypothesize that the efficiency of this protocol increases with the block height.

Sodium bentonite, graphite, light calcium carbonate and diatomite were used as parent minerals for the mineral-based porous granulated material （MPGM） which was tested for the removal of methyl orange （MO）, a cationic dye, fIom aqueous solution. The adsorption capacity was evaluated under the conditions of varied initial pH, adsorbent dosage, dye concentration, temperature, reaction time, and static regeneration. Experimental results showed that the maximum capacity of MPGM adsorbing MO was more than 80 mg·g-1 The adsorption equilibrium and kinetics of MPGM followed typical pseudo-first-order and Langmuir adsorption models respectively. The thermodynamic parameters of △G°, △H° and △S° showed that the adsorption was an endothermic and spontaneous process without remarkable change. The spent MPGM was regenerated 5 times and probable pathway for the efficient and re-utilizing adsorbent has been proposed. The results indicate that MPGM has a structure of silicon-aluminium-calcium-carbon, and could be employed as porous, low density, and large specific surface area alternatives for the removal of cations dyes from industrial wastewater.
