Pressure is an efficient tool to tune the electronic structure of iron-based superconductors. Here, we performed systematic high pressure transport and magnetization measurements on (Ca0.73La0.27)FeAs2 single crystal samples. Filamentary superconductivity is induced under a small applied pressure P=1.6 GPa. At P=3.2 GPa, the superconductivity becomes bulk. It is found that Tc increases initially and then decreases with further increasing pressure, forming a dome shape. Hall resistivity is measured simultaneously and the Hall coefficient RH at 50 K shows nonmonotonic dependence on pressure. In addition, RH reverse sign at a critical pressure Pc=3.9 GPa, where Tc reaches the maximum and there is a sudden increase in superconducting diamagnetism. Theoretical calculation results show a pressure induced Lifshitz transition of the Fermi surface which might be responsible for the appearance of superconductivity.

The conventional Hall effect is linearly proportional to the field component or magnetization component perpendicular to a film [1]. Despite the increasing theoretical proposals on the Hall effect to the in-plane field or magnetization in various special systems induced by the Berry curvature [2-8], such an unconventional Hall effect has only been experimentally reported in Weyl semimetals and in a heterodimensional superlattice [9-12]. Here, we report an unambiguous experimental observation of the antisymmetric planar Hall effect (APHE) with respect to the in-plane magnetic field in centrosymmetric rutile RuO2 and IrO2 single-crystal films. The measured Hall resistivity is found to be linearly proportional to the component of the applied in-plane magnetic field along a particular crystal axis and to be independent of the current direction or temperature. Both the experimental observations and theoretical calculations confirm that the APHE in rutile oxide films is induced by the Lorentz force. Our findings can be generalized to ferromagnetic materials for the discovery of anomalous Hall effects and quantum anomalous Hall effects induced by in-plane magnetization. In addition to significantly expanding knowledge of the Hall effect, this work opens the door to explore new members in the Hall effect family. Copyright © 2023, The Authors. All rights reserved.

Radioactive 129I, as one of the main products of the nuclear fission process, can be applied to track radioactive substance in the environment. So far, limited studies have investigated the spatio-temperal distribution of 129I in marine ecosystems although 129I has bee widely found via nuclear activities. Here, we report the concentrations of 129I in kelps collected from coastal waters off the Yellow Sea and East China Sea from 2009 to 2021. In 2011, the mean kelp 129I/127I ratios in these two regions increased by 5 times. Through simulation calculations, although the 129I released by Fukushima Daiichi Nuclear Power Plant (FDNPP) accident can reach the study area within a few weeks through atmospheric transport, but the concentrations of 129I is not sufficient to cause such a high level. The 129I emitted by European nuclear fuel reprocessing plants (NFRPs) settles into the soil and washed into coastal areas by rivers, which may be the main factor causing the increase of 129I in intertidal kelps. Unlike the rapid decline of 129I/127I ratios in the Yellow Sea in 2012, it showing a slow decreasing trend in the East China Sea, which could be attributed to large river inputs. The findings suggest that radionuclides released during a nuclear exploration on coastal ecosystems are crucial, and special attention should be paid when monitoring nuclear-related marine environment safety, especially in large river estuaries. © 2024, The Authors.

A FDTD method with the conformal modification is proposed to study electromagnetic properties of multilayer graphene (MLG). The vector fitting technique is employed to change the MLG conductivity model into an appropriate form for the FDTD implementation by an auxiliary differential equation formulation. Some numerical results are presented with the accuracy of our developed algorithm validated by comparing our results to the analytical ones, and the effects of layer number of MLG in the MLG-based structures as well as operating temperature are examined in detail.

The full potential of perovskite solar cells (PSCs) is limited by charge-carrier recombination, due to the imperfect passivation methods. Here, interfacial recombination loss of field-effect and chemical passivation mechanisms is quantified. It was found that a favorable alignment of energy levels can provide very good field-effects to reduce minority carriers, and suppresses interfacial recombination losses more effectively than chemical passivation. To obtain high-efficiency PSCs, two-dimensional (2D) perovskites are promising candidates, which offer powerful field-effects and only require modest chemical passivation at the interface. Owing to promoted passivation and charge-carrier extraction, the power conversion efficiency of a 2D/3D heterojunction PSC was boosted to 25.32% (certified 25.04%) for small-size devices and to 21.48% for a large-area module (with a designated area of 29.0 cm2). Ion migration is also suppressed by the 2D/3D heterojunction so that the unencapsulated small-size devices maintain 90% of the initial efficiency after 2000 h of continuous operation at the maximum power point. © 2023, The Authors.

In view of the situation of the bundled wind-photovoltaic-thermal generation system (BWPTGS) in China's new energy bases and the demand of carbon emissions reduction in generation system, this paper constructs a capacity planning method for wind-photovoltaic-thermal bundling power supply considering the life cycle carbon emissions. Based on the concept of low-carbon economy, this paper introduces carbon emission trading (CET) method into capacity planning of BWPTGS. Then, this paper calculates the carbon emissions cost of the generation system under the carbon emissions trading mechanism. With the objective of minimizing the comprehensive cost of generation system taking into account the cost of CET, the paper constructs an optimal generation system planning model for new energy bases considering carbon emission trading. The optimization model is applied to a BWPTGS for a new energy base in north-western China. Case studies are conducted to demonstrate the effectiveness of this proposed model and method.
