Effects of vortex and antivortex excitations in underdoped Bi2Sr2Ca2Cu3O10+δ bulk single crystals

Physical Review B 2024年第13期110卷 134509页

The observance of vortex and antivortex effects in bulk crystals can prove the existence of phase-disordered superconductivity in the bulk. To gain insights into the mechanisms that govern superconducting transition in copper oxide high-transition temperature (Tc) superconductors, this study investigated the transport properties of underdoped Bi2Sr2Ca2Cu3O10+δ (Bi-2223) bulk single crystals. The I−V characteristics results and the typical tailing behavior owing to the temperature dependence of in-plane resistivity (ρab) were consistent with the Kosterlitz-Thouless (KT) transition characteristics. Thus, with increasing temperature, copper oxide high-Tc superconductors transitioned to their normal state owing to destruction of their phase correlations, although a finite Cooper pair density was prevalent at Tc. Further, magnetization measurements were performed to determine the temperature dependence of the irreversible magnetic field Birr. Consequently, the mechanism governing the KT transition-like superconducting transition in this bulk system was elucidated. These results support the extreme strong-coupling models for high-Tc superconductivity in cuprates.

Genomics and Informatics 2024年第1期22卷 71-94页

Caenorhabditis elegans (C. elegans) is a nematode and model organism whose entire genome has been mapped, which allows for easy observation of the organism’s development due to its transparent structure, and which is appealing due to its ease of crossover, ease of culture, and low cost. Despite being separated by nearly a billion years of evolution, C. elegans homologs have been identified for the vast majority of human genes and are associated with C. elegans for many biological processes such as apoptosis, cell signaling, cell cycle, cell polarity, metabolism, and aging. A detailed bibliometric study is performed here to examine publication trends in this field. Data were taken from the Web of science database and analyzed using the bibliometric application Biblioshiny (RStudio). In terms of publication, the results indicated a gradual increase each year between 1980 and 2023. A total of 20,322 records were issued in 96 countries, the majority of which were in the USA, China, and Japan. The most prolific writers, the journals most engaged in the area, the nations, institutions, and keywords used by authors were all determined using the Web of science database and bibliometric rules. The number of papers in the C. elegans research field is increasing exponentially, and Genetics is the journal with the highest number of articles. This study presents how research patterns have evolved throughout time. As a result, worldwide cooperation and a potential field can be developed. © The Author(s) 2024.

Currently, a common approach to realize high-performance semiconducting polymers is to enhance the coplanarity of molecular chains. Among the numerous design strategies reported to fulfill this requirement, the introduction of vinyl bridges has proved to be one of the most effective approaches. In this study, we designed and synthesized four naphthalenediimide (NDI)-based dual-acceptor conjugated polymers comprising two different second acceptors, including benzothiadiazole (S) and benzotriazole (N), with vinyl bridges inserted to study the structure-performance relationships in transistors. We found that the presence of side chains in S and N causes subtle differences in rigidity, leading to an opposite trend in the vinyl bridge effect. The electron mobility of vNDI-N was successfully improved compared to that of the parent polymer (NDI-N) as a result of the fine optimization of the backbone coplanarity. However, the electron mobility of vNDI-S decreased compared to that of NDI-S. Analysis using UV-vis spectroscopy, simulations, and morphological techniques (AFM and GIWAXS) revealed that the absence of side chains in S leads to challenges in achieving planar bonding with neighboring moieties. This study highlights the importance of considering the rigidity of the coupling acceptors to optimize the ideal backbone conformation of NDI-based dual-acceptor copolymers. © 2024 The Authors.
