Paraffin/polyethylene/graphite composite phase change materials with enhanced thermal conductivity and leakage-proof

A general strategy to enhance the electrochemical activity and energy density of energy-storage materials through using sintering aids with redox activity: a case study of Mo4Nb26O77

“…In order to understand the lithium-storage mechanism of the Mo 4 Nb 26 O 77 submicron-sized particles, the crystal-structure evolution during the electrochemical reaction is analyzed based on in situ XRD at 25 and −10 °C. 42–45 Fig. 6a and b show the first-three-cycle two-dimensional and pristine in situ XRD patterns recorded at 0.4C and 25 °C with GCD curves, respectively.…”

Optical Characterization of Bitumen: Inspecting the Quantum Size Effect in the Nanostructured Phase

“…Noticeably a series of references refer to diffraction peaks around 21 and 23°, attributed to different diffraction planes in paraffin waxes, consequently, a crystalline phase. [26][27][28] Liu et al 29 attribute diffraction peaks at 21.17 and 23.53°to, respectively, diffraction by the planes (110) and ( 200), as extracted from JCPDS card no. 40-1995. From these results we are sure we found a degree of crystallinity in our sample of BIT, and that these s Figs.…”

Polyimide foam composites with nano-boron nitride (BN) and silicon carbide (SiC) for latent heat storage

“…It is also important to understand and monitor the dispersion dynamics of the particles in the PCM during the heating-cooling cycles, newly developed technologies such as in situ liquid phase TEM analysis can be highly suitable for these materials systems [27]. In summary, these flexible (see Figure S3 and the video file; Supplementary Information), thermally conductive and stable PCM composites produced by solvent-free processes with easy scale-up potential can be very useful for different energy management systems ranging from modern electronic devices to energy savings in buildings [62,63].…”
