Abstract
Abstract Thermoelectric power of carbon fiber reinforced cement composites was firstly enhanced efficiently by metallic oxide microparticles in the cement matrix. The absolute Seebeck coefficient of these composites increased steadily with increasing metallic oxide content and achieved 4–5 folds of the original one. The largest absolute thermoelectric power of +100.28 µV/°C was obtained for the composite with 5.0 wt% Bi 2 O 3 microparticles. The carrier scattering of the interface between oxide microparticles and cement matrix is probably attributed to the Seebeck effect enhancement.

Abstract This paper reviews carbon materials for significant emerging applications that relate to structural self-sensing (a structural material sensing its own condition), electromagnetic interference shielding (blocking radio wave) and thermal interfacing (improving thermal contacts by using thermal interface materials). These applications pertain to electronics, lighting (light emitting diodes), communication, security, aircraft, spacecraft and civil infrastructure. High-performance and cost-...

We report a giant Seebeck coefficient (S) thermoelectric (TE) material?MnO2 powder?and the design of a practical MnO2 TE generator to light up a regular light emitting diode (LED). The S of MnO2 powder was measured to be higher than 20?000??V?K?1, which is about 100 times higher than the state-of-the-art of Bi2Te3, one of the best TE materials. The giant S is very possibly closely related to the surface density of the electronic state (DOS), the Fermi energy level. The very high S and therefore ...

Poly(vinyl acetate) (PVAc) copolymer latex-based composites were prepared with multi-walled carbon nanotubes (MWCNT), stabilized with sodium deoxycholate (DOC) or meso-tetra(4-carboxyphenyl) porphine (TCPP). SEM images show that a segregated MWCNT network developed during drying, which resulted in relatively low percolation thresholds (1.62 and 2.17 wt.% MWCNT for DOC and TCPP, respectively). The electrical conductivity (σ) of TCPP-stabilized composites is very similar to that of DOC-stabilized,...

Energy harvesting (also known as power harvesting or energy scavenging) technology allows capturing unused ambient energy such as solar, wind, thermal, strain and kinetic, energy of gas and liquid flows and converting the energy into another form of usable energy. One form of ambient energy available from pavements is thermal energy derived from natural heating of pavements. The goal of this study was to determine if there is a possibility of capturing thermal energy from pavements and storing t...

Carbon fiber reinforced concrete can be used to sense temperature owing to the Seebeck effect caused by the p-type conductivity of short carbon fibers. Both the temperature sensing ability of the carbon fiber reinforced lightweight concrete and the influence of mineral admixtures on the Seebeck effect were investigated by measuring the thermo electric power of six Portland cement-based concretes with or without carbon fibers or mineral admixtures (fly ash, silica fume). It was found that the car...

Abstract A cement-based thermocouple in the form of a junction between dissimilar cement pastes and exhibiting thermocouple sensitivity 70±7 μV/°C is provided. The dissimilar cement pastes are steel fiber cement paste (n-type) and carbon-fiber silica-fume cement paste (p-type). The junction is made by pouring the cement pastes side by side.

Abstract The absolute thermoelectric power of carbon fiber-reinforced cement paste was rendered as negative as −17 μV/°C by using bromine-intercalated carbon fibers, which had a high concentration of holes. The corresponding paste with pristine carbon fibers exhibited absolute thermoelectric power as negative as −0.8 μV/°C only.

Abstract null null An analysis of the thermoelectric characteristics of certain recently discovered materials is carried out in this investigation. The alloy of iron, vanadium, tungsten, and aluminum (Fe2V0.8W0.2Al) applied to a silicon crystal is compared to new inorganic thermoelectric materials, which are mosly oxides like NaCO2O4. For both materials, the thermoelectric effects, Seebeck effect, Peltier effect, Thomson effect, and Kelvin relations are described. The cooling rate’s influence on...

Abstract null null The thermoelectric effect of the cement paste with the MnO2/carbon fiber composite inside was firstly reported in this work. The MnO2/carbon fiber composite was synthesized based on the redox reaction between potassium permanganate and carbon. After the reaction, α-MnO2 particles grew on the surface of carbon fiber. The nanorod-shaped MnO2 particles exhibit a diameter of about 50 nm and a length range of 100–300 nm. The weight ratio of MnO2 to carbon fiber is 37.6:62.4 in the ...
