| 1 | Flexible ternary carbon black/Bi_(2)Te_(3) based alloy/polylactic acid thermoelectric composites fabricated by additive manufacturing显示文摘Flexible ternary carbon black/Bi_(2)Te_(3) based alloy/polylactic acid(CB/BTBA/PLA)composites were fabricated by additive manufacturing and their thermoelectric properties were investigated from 300 K to 360 K.At 300 K,as the mass ratios of BTBAs in the composites increased from 38.5% to 71.4%,both the electrical conductivity and Seebeck coefficient of the composites increased from 5.8 S/cm to 13.3 S/cm,and from 60.2 mV/K to 119.9 mV/K,respectively,and the thermal conductivity slightly increased from 0.15 W m^(-1)K^(-1) to 0.25 W m^(-1)K^(-1),as a result,the ZT value of the composites increased from 0.004 to 0.023.As the temperature increased from 300 K to 360 K,the electrical conductivity of all the composites slightly decreased,while the thermal conductivity slowly increased,and a highest ZT value of 0.024 was achieved for the composites with 71.4% BTBAs at 320 K.Unlike traditional sterolithography,fused deposition modeling,selective laser melting,etc.,this additive manufacturing process can directly print the solutions which contain inorganic fillers and polymer matrixes into almost any designed intricate geometries of thermoelectric composites,therefore this process has great potential to be used for fabrication of flexible polymer based thermoelectric composites and devices. | Yong Du Jiageng Chen Qiufeng Meng Jiayue Xu Biplab Paul Per Eklund | 2020 | Journal of Materiomics2020，6，2： | 1 |

| 3 | Abrupt change of dielectric properties in mullite due to titanium and strontium incorporation by sol-gel method显示文摘Highly crystallized mullite has been achieved at temperatures of 1100℃and 1400℃by sol-gel technique in presence of titanium and strontium ions of different concentrations:G_(0)=0 M,G_(1)=0.002 M,G_(2)=0.01 M,G_(3)=0.02 M,G_(4)=0.1 M,G_(5)=0.2 M and G6=0.5 M.X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),field emission scanning electron microscopy(FESEM),LCR meter characterized the samples.Mullite formation was found to depend on the concentration of the ions.The dielectric properties(dielectric constant,loss tangent and AC conductivity)of the composites have been measured,and their variation with increasing frequency and concentration of the doped metals was investigated.All the experiments were performed at room temperature.The composites showed maximum dielectric constants of 24.42 and 37.6 at 1400℃of 0.01 M concentration for titanium and strontium ions at 2 MHz,respectively.Due to the perfect nature of the doped mullite,it can be used for the fabrication of high charge storing capacitors and also as ceramic capacitors in the pico range. | Biplab Kumar PAUL Kumaresh HALDAR Debasis ROY Biswajoy BAGCHI Alakananda BHATTACHARYA Sukhen DAS | 2014 | Journal of Advanced Ceramics2014，3，4： | 0 |
| 4 | Tailoring thermal conductivity by engineering com- positional gradients in Sil-xGex superlattices显示文摘The transport properties of artificially engineered superlattices (SLs) can be tailored by incorporating a high density of interfaces in them. Specifically, SiGe SLs with low thermal conductivity values have great potential for thermoelectric generation and nano-cooling of Si-based devices. Here, we present a novel approach for customizing thermal transport across nanostructures by fabricating Si/Sil-xGex SLs with well-defined compositional gradients across the SiGe layer from x = 0 to 0.60. We demonstrate that the spatial inhomogeneity of the structure has a remarkable effect on the heat-flow propagation, reducing the thermal conductivity to -2.2 W.m-1.K-1, which is significantly less than the values achieved previously with non-optimized long-period SLs. This approach offers further possibilities for future applications in thermoelectricity. | Pablo Ferrando-Villalba1 Aitor F.
