Tind iselenide (SnSe 2 ), as an anodem aterial,h as outstandingp otential for use in advanced lithium-ion batteries. However,l ike other tin-based anodes, SnSe 2 suffers from poor cycle life and low rate capabilityd ue to large volume expansion during the repeated Li + insertion/de-insertion process. This work reports an effectivea nd easy strategy to combine SnSe 2 and carbon nanotubes (CNTs) to form a SnSe 2 /CNTsh ybrid nanostructure. The synthesized SnSe 2 has ar egularh exagonal shape with at ypical 2D nanostructure and the carbon nanotubes combine well with the SnSe 2 nanosheets. The hybrid nanostructure can significantly reduce the serious damage to electrodes that occurs during electrochemical cycling processes. Remarkably,t he SnSe 2 / CNTse lectrodee xhibits ah igh reversible specific capacity of 457.6 mA hg À1 at 0.1 Ca nd 210.3 mA hg À1 after 100 cycles. At ac ycling rate of 0.5 C, the SnSe 2 /CNTse lectrode can still achieve ah igh value of 176.5 mA hg À1 ,w hereas av alue of 45.8 mA hg À1 is achieved for the pure SnSe 2 electrode. The enhanced electrochemical performance of the SnSe 2 /CNTs electrode demonstrates its great potential for use in lithiumion batteries.T hus, this work reports af acile approacht o the synthesis of SnSe 2 /CNTsa sap romising anode material for lithium-ionb atteries.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Ongoing improvements in building envelope technologies suggest that residences will soon be routinely constructed with low heating and cooling loads. The use of novel building materials containing active thermal components (e.g., PCM, subventing, radiant barriers, and integrated hydronic systems) would be an ultimate step in achieving significant heating and cooling energy savings from technological building envelope improvements. The key benefit of using PCM is that it affords structures improved thermal storage capabilities with minimal change to the existing building design (Sharma 2013). The main methods for incorporating PCM into building materials include the use of gypsum plaster boards and other structural boards, blending PCM with thermal insulations, and by macro-packaging. The thermal energy storage property of PCM is based on its latent heat storage capacity, given that large amounts of energy can be stored in a small volume. Therefore, the material containing PCM can absorb and release heat more effectively than conventional building materials. However, the selection of the PCM locations, PCM transition temperature range, and the amount of used PCM are essential for effective and durable use of the PCM-enhanced technologies, considering a relatively long life span of building envelopes.Present-day residential and commercial buildings are becoming more structurally lightweight, and concerns are been raised over indoor thermal comfort due to reduced thermal storage potential. A strong tension exists between the drive to build better efficient structures with less impact on the environment and the tendency to add more mass to the structure for thermal storage. These issues are further heightened by global climate change and the continual rise in energy cost. Without counting traditional arctic ice igloo constructions, the use of PCM in buildings began in the mid-1940s and this passive solar system with thermal storage capability was one of the first applications studied at that time (Telkes 1978;Frysinger and Sliwkowski 1987;. During the 1980s, bulk

“…When the MEPCM layer was at an adequate thickness, it provided optimum control over the temperature of the PV module under different climatic conditions. Comprehensive reviews on PCMs, including their thermophysical properties, long-term stability, impregnation methods, current building applications, and thermal performance analyses, can be found in the literature in addition to numerical building simulations with PCMs [12][13][14][15][16][17][18][19][20][21].…”
