Title: Hexagonal and monoclinic phases of La2O2CO3 nanoparticles and their phase-related CO2 behavior

Abstract: In this study, we prepared hexagonal and monoclinic phases of La2O2CO3 nanoparticles by different wet preparation methods and investigated their phase-related CO2 behavior. The monoclinic La2O2CO3 phase was synthesized by a conventional precipitation method via La(OH)CO3 structure when the precipitation time was longer than 12 h. In contrast, the hydrothermal method produced only the hexagonal La2O2CO3 phase irrespective of the hydrothermal reaction time. The La(OH)3 phase was determined to be the initial phase in both preparation methods. During the precipitation, the La(OH)3 phase was transformed into La(OH)CO3 owing to the continuous supply of CO2 from air whereas the hydrothermal method of a closed system crystallized only the La(OH)3 phase. On the basis of the CO2-temperature programmed desorption and thermogravimetric analysis, the hexagonal La2O2CO3 nanoparticles (HL-12h) showed higher surface CO2 adsorption and thermal stability than those of the monoclinic La2O2CO3 (PL-12h). The crystalline structures of both La2O2CO3 phases predicted by the density functional theory calculation explained the difference in the CO2 behavior on each phase. Consequently, HL-12h generated higher current density than PL-12h in cyclic voltammograms of CO2 electrochemical reduction.

Abstract: The construction of the heterojunctions in the sensing materials has been widely applied to improve the gas sensing performances of the composites composed of nanostructured metal oxides. This review summarized the recent progress on the assemble methods and the gas sensing behaviors of the sensors based on the nanostructured metal oxide heterojunctions. Various methods, including the hydrothermal process, electrospinning and chemical vapor deposition, have been successfully to establish the metal oxide heterojunctions in the sensing materials. The sensor based on the built nanostructured heterojunctions were found to exhibit enhanced gas sensing performances with higher sensor responses and shorter response times to the targeted reducing or oxidizing gases compare with those of the pure metal oxides. Moreover, the enhanced gas sensing mechanisms of the metal oxide-based heterojunctions to the reducing or oxidizing gases were also discussed with mainly emphasizing the important role of the potential barrier or the accumulation layer.
Title: Dendritic polymers as promising additives for the manufacturing of hybrid organoceramic nanocomposites with ameliorated properties suitable for an extensive diversity of applications

Abstract: The physicochemical idiocrasies of dendritic polymers have inspired their implementation as templates for complex structures. Ceramics are distinguished for their mechanical superiority and absorption potential that render them ideal substrates for separation and catalysis technologies. The integration of dendritic materials to the inorganic hosts can be achieved through chemical attachment of the organic moiety onto functionalized surfaces, impregnation and absorption inside the pores, conventional sol-gel reactions or via biomimetic mediation of dendritic matrices, inducing the formation of usually spherical hybrid nanoparticles. Alternatively, dendritic polymers can propagate from ceramic scaffolds. Optimization techniques as well as established and prospected applications are also discussed.

Abstract: As the fast development of fexible devices in recent years, great attention has been raised in flexible and stretchable energy storage/conversion devices, which may directly be put on with long stanby time and low safefy risk. Considering the features, such as cost, safety, volome energy density and environmental friendliness, Zinc–air batteries hold a good promise for portable and fexible applications. Here in this mini-review, we focused on the main challenges of the flexible and wearable Zinc–air batteries based on solid state and semi solid state electrolytes and the up-to-date progress from materials to technologies towards overcoming these technical issues. We first overviewed the design and working mechanism of the flexible batteries and classified the batteries into two types：fibre-shaped and stack-shaped. Then, detailed discussions have been offered on the latest progress to address these technical issues based on the nano/micro- materials. Finally, future perspectives are provided in the end, which may shed light on the coming research and design of wearable Zinc-air batteries.
