Context. Solar active regions (ARs) are often surrounded by dark large areas of reduced emission compared to the quiet Sun, observed at various wavelengths corresponding to the chromosphere, transition region (TR), and corona, known as dark halos (DHs). The mechanisms behind the darker emission of DHs remain unclear and merit a wider scope of study.
Aims. This study aims to investigate for the first time the fine structure of a DH observed by the EUV High Resolution Imager (HRIEUV) on board the ESA’s Solar Orbiter (SO) mission and its appearance in the TR.
Aims. We utilized the extensive 1 hour dataset from SO on 19 March 2022, which includes high-resolution observations of NOAA 12967 and part of the surrounding DH. We analyzed the dynamics of the HRIEUV DH fine structure and its appearance in the HRILyα image. We also analyzed the Spectral Imaging of the Coronal Environment (SPICE) Lyβ, C III, N VI, O VI, and Ne VIII lines, which sample the TR in the log T(K) ∼ 4.0–5.8 range. This analysis was complemented with a simultaneous BLOS magnetogram taken by the High Resolution Telescope (HRT).
Methods. We report the presence of a peculiar fine structure that has not been observed for the quiet Sun. It is characterized by combined bright EUV bundles and dark regions, arranged and interconnected in such a way that they cannot be clearly separated. They form a spatial continuum extending approximately radially from the AR core, suggesting a deep connection between the DH and the AR. Additionally, we find that the bright EUV bundles are observed in all the SPICE TR lines and the HRILyα band and present photospheric BLOS footprints in the HRT magnetogram. This spatial correlation indicates that the origin of the 174 Å DH may lie in the low atmosphere: the photosphere and chromosphere.

In the last decades, nonlinear optical microscopy techniques, such as two-Photon Excited Fluorescence (2PEF), Sum Frequency Generation (SFG), and Hyperspectral Coherent Anti-Stokes Raman Scattering (H-CARS) microscopy, emerged as powerful tools to image biological samples in a label-free, fast, and non-destructive way. Traditionally, these techniques are performed with single point-scanning acquisition schemes featuring a limited field of view and often leading to sample damage when high laser power is used to increase the acquisition speed. Wide-field illumination and camera-based detection schemes offer a solution to these issues, enabling fast imaging over a large field view. However, current laser sources used for nonlinear microscopy operating at several MHz repetition rates are not able to induce nonlinear effects over areas larger than 100 × 100 µm2. Here, we present a powerful 200 kHz repetition rate laser source based on an Ytterbium fiber laser pumping two picosecond optical parametric amplifiers tunable in the 700–900 nm spectral range and rapidly tunable (up to 100 KHz) within a 20 nm sub-range. We exemplify the possibilities of this laser system to perform rapid CARS spectroscopy (2 ms/spectrum) and nonlinear wide-field imaging, up to 3.3 frames/s for 2PEF and SFG and 0.3 hypercubes/s for H-CARS, over a field of view &gt;300 × 300 µm2.

We have synthesized L-cysteine and oleylamine stabilized CsPbBr3 perovskite quantum dots (PQDs) and coupled them with gold nanoparticles (AuNPs). The PQDs and AuNPs, as well as their hybrid nanostructures (HNS), were characterized using UV–visible (UV–vis) and photoluminescence (PL) spectroscopy. The UV–vis spectra show absorption bands of the HNS at 503 and 520 nm, attributed mainly to PQDs and AuNPs, respectively. The PQDs show a strong excitonic PL band peaked at 513 nm from PQDs. The HR-TEM results show the formation of hybrid structures between PQDs and AuNPs, which is also supported by the PL quenching of the PQDs by the coupled AuNPs. Ultrafast dynamics of the exciton and charge carriers in the HNS and pristine PQD were studied using femtosecond transient absorption. Multiexponential fitting of the dynamic data revealed the existence of shallow and deep trap states in pristine PQDs and ultrafast electron transfer from PQDs to AuNPs in the HNS. A kinetic model was proposed to account for the key dynamic processes involved and to extract the time for electron transfer from PQDs to AuNPs in the HNS, found to be ∼2 ps. Dynamic processes in pristine PQDs are largely unchanged by HNS formation with AuNPs.

Published: September 2024

Low-energy (0–14 eV) resonance electron interaction and fragment species produced by dissociative electron attachment (DEA) for enantiomeric forms of glutamic acid (Glu) are studied under gas-phase conditions by means of DEA spectroscopy and density functional theory calculations. Contrary to a series of amino acids studied earlier employing the DEA technique, the most abundant species are not associated with the elimination of a hydrogen atom from the parent molecular negative ion. Besides this less intense closed-shell [Glu – H]– fragment, only two mass-selected negative ions, [Glu – 19]– and [Glu – 76]–, are detected within the same electron energy region, with the yield maximum observed at around 0.9 eV. This value matches well the energy of vertical electron attachment into the lowest normally empty π* COOH molecular orbital of Glu located at 0.88 eV according to the present B3LYP/6-31G(d) calculations. Although the detection of asymmetric DEA properties a priori is not accessible under the present experimental conditions, “chirality non-conservation” can be associated with some decay channels. Evidently, the measured spectra for the L- and D-forms are found to be identical, the results, nevertheless, being of interest for the forthcoming experiments utilizing spin-polarized electron beam as a chiral factor in the framework of conventional DEA technique.

Published: September 2024

Background Aging women living with HIV are significantly affected by menopause and comorbidities, yet international and Australian HIV guidance on the management of women is scarce. This study aimed to identify gaps in clinical management of menopause, age-related comorbidities, and psychosocial health of women living with HIV attending our metropolitan sexual health service. Methods A clinical audit of all cisgender women who attended Sydney Local Health District Department of Sexual Health Medicine for ongoing routine HIV care between 1 January 2021 and 1 January 2023 was undertaken. Results Twenty-seven patient files were examined. Half (13/27, 48.1%) of women were age 45 years and older, of whom 6/13 (46.2%) were postmenopausal and 4/13 (30.8%) did not have menopause status recorded. In the prior 12 months, most women had their blood pressure (19/27, 70.4%), total cholesterol (21/27, 77.8%), glycated haemoglobin (21/27, 77.8%), estimated glomerular filtration rate (27/27, 96.3%), and liver function tests (26/27, 96.3%) measured. Smoking and alcohol intake was documented for less than half of women (13/27, 48.1%; and 12/27, 44.4%; respectively). In women aged 45 years and older, absolute cardiovascular disease risk was calculated in 2/13 (15.4%), and none had a Fracture Risk Assessment Tool score or cognitive screen performed in the prior 12 months. One-fifth (5/27, 18.5%) had a documented history of depression or anxiety. Of those screened, half (4/8, 50.0%) disclosed past intimate partner violence. Conclusions Our service has now implemented a reference tool to guide routine monitoring of women living with HIV, with sections dedicated to reproductive health and psychological wellbeing. Australian HIV management guidelines would benefit from specific guidance for women.
Salience management
Authors: Liu Ping , Xu Wenli 
Published: September 2024

Abstract
This article zooms in on metadiscourse resources to explore their salience management in online new product launch
(hereafter NPL) conferences, adopting the salience theory of socio-cognitive approach (hereafter SCA) as the theoretical
foundation. Drawing on data from 16 online NPL conferences presented by non-native English speakers, it is found that
different types of metadiscourse resources are employed to manage the salience of specific contextual factors in metacognitive,
metarepresentational and metacommunicative dimensions, motivated by the presenter’s inherent salience and awareness of recipient
design. This article not only strengthens the assumption that the salience theory of SCA can provide a new perspective for
metadiscourse research, but also sheds light on how to understand the effectiveness of online business communication in the
intercultural context.

Authors: Zhang Xiangrui , Lei Liang , Tang Lin , Zhu Kai , Zhou Kuan , Yang Huachao 
Published: September 2024

Abstract
This work reveals the capacitive behaviors of graphene nanomaterials in typical ionic liquids of [BMI+] [BF4
−] using molecular dynamics simulations. It is found that the charging process induces a structural transition from disordered to partially ordered and then ordered multilayer structures of [BMI+][BF4
−] electrolyte, yielding a multiple layer-by-layer packing structure of BMI+ cation and BF4
− anion. Especially, a counterion-adsorption-dominated Helmholtz layer is revealed at a high charge density of 16 μC/cm2, which is primarily responsible for the superior capacitance results. Besides, the differential capacitance of [BMI+][BF4
−] exhibits a symmetric convexity-shaped curve, showing a maximal capacitance value of 4.83 μF/cm2. The as-obtain simulation results help to understand the microscopic charge storage mechanisms of graphene in ionic liquids.

Published: September 2024

Abstract
In this study, a hybrid graphene/manganese dioxide/poly(2,2’-dithiodianiline) (graphene/MnO2/PDTDA) composite material was in-situ prepared by chemical oxidative polymerization of PDTDA in graphene/MnO2 and applied as supercapacitor electrode materials in alkaline electrolyte. The morphology, structure, and particularly the electrochemical performances of such graphene/MnO2/PDTDA composite was characterized by XRD, SEM, FTIR, and electrochemical tests. The results showed that the graphene/MnO2/PDTDA ternary composite possessed the advantages of both double-layer capacitance and Faraday’s pseudocapacitance behaviours, thus leading to the highest specific capacitance of 96.35 F·g−1 as compared to the binary MnO2/PDTDA electrode material (35.26 F·g−1) at a current density of 10 mA·cm−1, implying potential candidate in future supercapacitor electrode materials.

Authors: Zhang Weihua , Guan Shizhe 
Published: September 2024

Abstract
For the photovoltaic cells in the local shade due to the difference in light intensity caused by the temperature inhomogeneity, affecting the surface heat transfer problem, this paper establishes the surface heat transfer model of photovoltaic cells in the local shade through the use of MATLAB analysis of photovoltaic cells surface heat transfer characteristics, to explore the mechanism and laws of heat transfer of photovoltaic cells in the local shade. The simulation results show that the convective heat transfer increases with the increase of the area of the shaded area, and the convective heat transfer with a wind speed of 2.5 m/s increases by about 77.2% compared with that with a wind speed of 1 m/s. The surface heat transfer of PV cells under partial shading increases with the rise of the area of the shaded area, and the surface heat transfer of PV cells under partial shading increases by about 77.2%. When the temperature of the shaded area is 20 K higher than that of the unshaded area, the radiative heat transfer of full shade increases by 19.3% on average compared with that of unshaded, and increasing the area of the shaded area increases the loss of radiative heat transfer. The output power of photovoltaic cells decreases with the increase of transmittance ratio or the enhancement of light intensity in both shaded and unshaded areas.
Simultaneous recovery of salt differential energy and chemical energy from wastewater by bioelectrochemical system
Authors: Ke Shengjin , Jiang Xuhui , Zhang Xi , Wang Song 
Published: September 2024

Abstract
Bioelectrochemical systems (BESs) serve as an emerging renewable energy technology that presents great potential for wastewater treatment and energy recovery. Microbial desalination cell (MDC), as a type of BES, is capable of desalination while realizing wastewater treatment and recycling of electric energy, which has become a research hotspot in recent years. However, research that has been conducted tends to focus only on the desalination capacity of the MDC and pays less attention to its electricity generation performance. The electricity derived from the recovery of chemical energy in the wastewater by the system has also not been well utilized. In this study, a microbial reverse-electrodialysis cell (MRC), which is capable of obtaining the salt difference energy from high-salt wastewater, was constructed and coupled with an electrodialysis cell (EDC), ultimately constructing a new type of BES named MRC-EDC. It can synchronize the recovery of chemical energy and salt difference in high-salt wastewater, realizing the in-situ use of electric energy and wastewater desalination. The maximum power production performance of MRC-EDC reached 2.44 W m−2, which was 67.1% higher than that of conventional MFC. The COD removal rate of the system reached 34.16% after 10 h of operation, and the average desalination rate per hour was 5.15%. This study provides a reference for the construction of high-efficiency BESs.

Published: September 2024

Abstract
Quasi-solid-state electrolytes encounter great obstacles in structural stability due to their inherent heterogeneity. Here, we introduce a new composite structure of glass-fiber-based metal-organic gel as a solid-state electrolyte and explore its electrochemical properties in lithium-metal batteries. We use a straightforward in-situ sol-gel method to synthesize this composite electrolyte, where glass fiber acts as matrices, ferric nitrate reacts with trimeric acid to form interconnected channels with abundant unsaturated metal sites, while ionic liquid electrolyte is in-situ confined into interconnected channels. The as-prepared composite electrolyte membrane has a uniform structure and composition, exhibiting a high room-temperature ionic conductivity of 1.79×10−3 S cm−1 and a high electrochemical oxidation potential of 4.76 V vs Li/Li+. This composite has excellent cycling performance in LiFePO4//Li (99.5% after 100 cycles) and NCM811//Li (86.6% after 200 cycles) batteries.

Published: September 2024

Abstract
As a newly proposed physical energy storage method, gravity energy storage (GES) is currently in its infancy at home and abroad, and the control technology of slope GES is not yet mature. This article focuses on the control strategy of the slope GES system, designs the machine/grid side control block diagrams with the sliding mode control technology, and compares the differences between sliding mode control and traditional PI control through simulation analysis. It is concluded that the sliding mode control strategy has a faster adjustment speed, smaller fluctuation range, and better overall control performance.

Published: September 2024

Abstract
At present, the structure of power supply in China has changed, and the positioning of thermal power units has gradually changed from the original main power supply to the adjustable power supply for peak regulation and frequency modulation. Peaking unit need to respond quickly to load changes while also considering economic efficiency, which means setting operating parameters more accurately. Association rules have achieved good application effects in the data mining of thermal power plant operation data. This article uses the historical operation data of a certain 600MW unit to explore the relationship between operating parameters and coal consumption under various peak load conditions, and obtain the optimized values of operating parameters. The results indicate that optimized parameters can improve the economic efficiency of peaking unit, and have certain practical value for setting operating parameters of boilers in deep peaking unit.

Abstract
This work reports the test of an n-type silicon pad array
detector at the CERN PS in the context of the future Forward
Calorimeter (FoCal) detector. FoCal is a proposed upgrade in the
ALICE detector operating within the pseudorapidity range of
3.2 < η < 5.8. It aims to measure direct photons, neutral
hadrons, vector mesons, and jets for the study of gluon saturation
effects in the unexplored region of low momentum
fraction x (∼ 10-5–10-6). The prototype is a
8×9 n-type Si pad array detector with each pad occupying one
cm2 area, fabricated on a 6-in, 325 ± 10 μm thick, and
high-resistivity (∼ 7 kΩ cm) Si wafer, which is
readout using the HGCROCv2 chip. The detector is tested using pion
beams of energy 10 GeV and electron beams of energy
1–5 GeV. The measurements of the Minimum Ionizing Particle (MIP)
response of pions and the shower profiles of electrons are
reported.

Published: September 2024

Abstract
One of the primary goals of the Center for Accelerator
Target Science (CATS) is to provide targets and foils in support of
the ATLAS User Facility and the Low-Energy community at large. While
a wide array of target production techniques are available at CATS,
new methods that must be explored invariably arise. One such
technique, the High-Intensity Vibrational Powder Plating (HIVIPP),
was first reported in 1997 by Isao Sugai. It was developed to
produce targets and stripper foils that were difficult to make by
standard methods. At Argonne National Laboratory (ANL), we have
successfully constructed and tested a simple system for this
purpose. We have produced targets of carbon and titanium on various
metal backings using the HIVIPP method. We are currently in the
exciting phase of exploring the production of other elements,
including isotopically enriched and radioactive material. This work
is in progress and will be further detailed with specific examples.
Toward integrated dam assessment: evaluating multi-dimensional impacts of the Grand Ethiopian Renaissance Dam on Sudan

Published: September 2024

Abstract
The Grand Ethiopian Renaissance Dam (GERD) on the Nile is expected to influence many ecosystem services, such as flood regulation, hydro-electricity production, food supply, and habitat provision, among others. Understanding these impacts (positive and negative) requires a comprehensive evaluation framework. This study develops and applies an integrated simulation framework for assessing the impacts of the GERD on Sudan, focusing on the simultaneous economywide effects of riverine flood hazards, irrigation water supply, hydropower generation, and floodplain-dependent industries, namely traditional fired clay brick production. The simulation framework incorporates three models: a river infrastructure system model, a flood model, and a Computable General Equilibrium Model. Results indicate positive impacts for hydropower generation and flood control, marginal benefits for water supply to existing irrigation, and negative consequences for brick production and the construction sector. Assuming that the GERD starts its long-term operation in 2025, we find an overall positive economic impact on Sudan’s Gross Domestic Product in 2025, with an increase of up to just over 0.1%, subject to river flow conditions. Recognizing the differences in impacts across sectors and income groups, the study emphasizes the need for interventions that ameliorate negative effects. While the study captures several impacts, other effects on the environment, recession agriculture, and soil fertility require further investigation. Still, our findings underscore the importance of adopting an integrated simulation approach to dam evaluation, acknowledging the interconnected nature of water and related sectors in national economies.
