High Performance Porous Triboelectric Nanogenerator Based on Silk Fibroin@MXene Composite Aerogel and PDMS Sponge

ACS Materials Letters (2023)

Xueqiang Tan Shuting Wang Zhongyuan You Jimin Zheng Ying Liu

In this work, we fabricated a high-performance and biocompatible porous triboelectric nanogenerator (TENG) with friction layers made by silk fibroin (SF)@MXene composite aerogel (SF@MXene-A) and a PDMS sponge. The incorporation of MXene into the SF aerogel increases the specific surface area as well as the resulting surface charge density, providing a way for designing a high-performance aerogel TENG. The TENG with the biocompatible SF aerogel achieves an optimum output performance at a ratio of MXene to SF of about 1:1, obtaining a maximum open-circuit voltage (Voc) of 545 V and maximum short-circuit current (Isc) of 16.13 μA. The Voc of our SF@MXene-A based TENG is about 2–3 times larger than the reported best values of other aerogel-based TENGs. In addition, owing to the recognized biocompatibility and advantageous air permeability of the SF@MXene-A, we designed a bioporous TENG mask that diagnoses asthma symptoms. The SF@MXene-A based TENGs have potential applications as wearable devices for diagnosing breath-relevant diseases.

Synthesis, physical properties, and annealing investigation of new layered Bi-chalcogenide LaOBiHgS ₃

Chinese Physics B (2019)

Yi Yu Chunchang Wang Liang Li Qiuju Li Chao Cheng

The transport and thermoelectric properties together with annealing of the new layered Bi-chalcogenide LaOBiHgS3 are studied. On the transport part, the insulating behavior of the as-grown sample is evidently depressed by post annealing. A hump-like abnormality appears around 170 K. The thermoelectric performance of the sample is observably improved by the annealing, mainly because of the enhanced electrical conductance. The present results suggest that the physical properties of LaOBiHgS3 are sensitive to post annealing and the possible micro adjustments that follow, indicating the layered Bi-chalcogenide family to be an ideal platform for designing novel functional materials.

Dielectric relaxation induced internal electric field and its effect on magnetoelectric state in Co₄Nb₂O₉

Journal of the American Ceramic Society (2017)

Yuanmiao Xie Hao Zang W. D. Ceng Shuting Wang Chunchang Wang

Abstract Pyrocurrent and dielectric properties of magnetoelectric antiferromagnet Co 4 Nb 2 O 9 have been investigated. The sample shows 2 thermally activated dielectric relaxations in the temperature range far above Néel temperature with the low‐ and high‐temperature ones being a dipolar and Maxwell‐Wagner relaxations, respectively. Two types of dipoles: relaxing dipoles and magnetic‐field‐induced dipoles were found in the sample. An internal electric field is formed due to the ordering of relaxing dipoles. Three current peaks were observed. The 2 higher temperature current peaks correspond to the dielectric relaxations. The lowest temperature current peak contains a positive tip and negative dip. The tip and dip are related to the depolarization of ferroelectricity induced by external and internal fields, respectively.

Maxwell-Wagner Relaxations in Ca-, Sm- and Nd-doped Ceria

Research Square (Research Square) (2021)

Rida Ahmed Shuting Wang Sajid Ur Rehman Jie Sun Jin Wang

Abstract Doped ceria, i.e. Ce 1-x M x O 2-d with M being dopant metal, has been a focus of great attention for SOFCs due to its high oxygen conduction. In the past literature, the dielectric relaxations in these materials have been ascribed to be caused by defect associates (MCeʺ-Vö) possessing different MCeʺ and Vö distances. But we believe that with changing measurement and analysis techniques it is necessary to invest our time to re-examine the already reported materials and to again take a detailed investigation of the underlying phenomenon behind their dielectric relaxations. Thus, we have used solid-state reaction to prepare Ce 1-x M x O 2-δ with M=Ca, Sm, and Nd in x=0.1, 0.2, and 0.3 ratios, respectively. The as-prepared and post annealed samples were tested for dielectric properties from 300-1080 K with varying frequencies. The low-temperature relaxation (R1) was argued to be a Maxwell-Wagner relaxation caused by humidity sensitivity. The high-temperature relaxation (R2) was ascribed to be caused by hopping motion of oxygen vacancies. This fact was also supported by detailed analysis of impedance spectra. While, according to the previous reports this relaxation is because of oxygen-vacancy-dopant defect pair.
