“…Calero et al prepared the Bi 2 Te 3y Se y electrodeposited thin films and achieved a Seebeck coefficient of 120 µVK -1 for as-deposited films [12]. A Seebeck coefficient of 138 µVK -1 has been reported by Danine et al for P-type Bi-Sb-Te 60 nm nanowire [13]. Besides the low value of Seebeck coefficient of the order of µVK -1 , several other problems are associated with above-mentioned materials such as toxicity, high manufacturing cost, and paucity of materials that have thus limited their widespread use [7,14,15].…”

In this work, a new class of highly-conductive chemically cross-linked gel has been synthesized by the confinement of water and IL N, N, N triethyl octyl ammonium bromide ([N 2228 ] Br) in polyethylene glycol dimethacrylate (PEGDMA) matrix, using in situ thermally initiated radical polymerization loaded with 1 wt. % free radical initiator azobisisobutyronitrile (AIBN). This novel gel was named as hydroionogel (HIG). The thermoelectric properties of HIG such as ionic conductivity, Seebeck coefficient, and thermal conductivity were measured and owing to its high thermoelectric performance, we referred to this as crosslinked thermoelectric hydro-ionogel, henceforth will be denoted by X-TEHIG. For all the measurements, coin cells were fabricated using commercial LIR 2032 stainless steel battery casings with X-TEHIG sandwiched between the two graphene electrodes. The ionic conductivity of X-TEHIG was examined via AC impedance spectroscopy technique by using a Gamry apparatus. Remarkably, the ionic conductivity of X-TEHIG was higher than that of neat [N 2228 ] Br. A linear increase in ionic conductivity of X-TEHIG as a function of temperature was recorded that showed a considerably higher value of 74 mScm -1 at 70 °C. The origin of this high conductivity is attributed to interactions between PEGDMA monomers and cations and anions of the IL and formation of hydrogen bonds between water and Branion, O-H•••Br -. X-TEHIG demonstrated a higher Seebeck coefficient of 1.38 mVK -1 . The Fourier transform infrared (FTIR) spectroscopy results revealed the successful polymerization of X-TEHIG by the disappearance of C=C peak of methacrylate group in the spectrum of PEGDMA. These results suggest that X-TEHIG may be a potential candidate for thermoelectric applications owing to their high values of ionic conductivity and Seebeck coefficient.

“…Furthermore, it is well-known that Bi 2 Te 3 can switch its n-type or p-type semiconductor response if it is doped with Se and Sb, respectively. Various ternary NWs based on Sb-doped Bi-Te [136,[148][149][150][151][152][153][154][155] and Se-doped Bi-Te NWs [147,149,156,157] have also been developed using the electrodeposition method. In 2013, Baßler et al published p-and n-type single-crystalline NWs of bismuth antimony telluride and bismuth telluride selenide grown by the template-based millisecond pulsed electrochemical deposition in self-ordered Al 2 O 3 membrane templates [149].…”

The recent advancements in thermoelectric materials are largely credited to two factors, namely established physical theories and advanced materials engineering methods. The developments in the physical theories have come a long way from the “phonon glass electron crystal” paradigm to the more recent band convergence and nanostructuring, which consequently results in drastic improvement in the thermoelectric figure of merit value. On the other hand, the progresses in materials fabrication methods and processing technologies have enabled the discovery of new physical mechanisms, hence further facilitating the emergence of high-performance thermoelectric materials. In recent years, many comprehensive review articles are focused on various aspects of thermoelectrics ranging from thermoelectric materials, physical mechanisms and materials process techniques in particular with emphasis on solid state reactions. While bottom-up approaches to obtain thermoelectric materials have widely been employed in thermoelectrics, comprehensive reviews on summarizing such methods are still rare. In this review, we will outline a variety of bottom-up strategies for preparing high-performance thermoelectric materials. In addition, state-of-art, challenges and future opportunities in this domain will be commented.

“…This method is widely used to fill the pores of track membranes with various metals and is well described in Refs. [38][39][40][41][42][43]. The essence of this method is galvanic metal deposition from a solution of its salt into the etched through channels (pores) of the track membrane.…”

This paper presents data about the radiation-protective characteristics of multilayer polyimide/lead (PI/Pb) composites for X-ray radiation. Multilayer composites were obtained by collecting lead-filled polyimide track membranes into a sandwich of the required thickness. ( Am) 241 = (E 59.5 keV) and ( Cd) 109 = (E 88 keV) isotopes were used as an X-ray radiation source. To assess the effect of lead filler particle size on the radiation-protective characteristics of a multilayer structure, data are presented on mathematically modeling the passage of 10-88 keV wavelength X-rays with through a composite. The experimental values of the attenuation coefficients of X-ray waves for a multilayer structure are 12-15% higher than the calculated ones. The increase in the attenuation coefficients obtained experimentally, compared with theoretical, is explained by using the proposed multilayer structure with lead particles in the nanoscale range.
