Published: October 2024

ABSTRACTBackgroundPersonal recovery is valued by people with bipolar disorder (BD), yet its conceptualisation is unclear. Prior work conceptualising personal recovery has focussed on qualitative evidence or clinical factors without considering broader psychosocial factors. This study used a network analysis of Bipolar Recovery Questionnaire (BRQ) responses, aiming to identify (1) independent relationships between items to identify those most “central” to personal recovery and (2) how the relationships between items reflect themes of personal recovery.MethodsThe model was developed from BRQ responses (36 items) from 394 people diagnosed with bipolar disorder. The undirected network was based on a partial correlation matrix and was weighted. Strength scores were calculated for each node. Community detection analysis identified potential themes. The accuracy of the network was assessed using bootstrapping.ResultsTwo consistent communities were identified: “Access to meaningful activity” and “Learning from experiences.” “I feel confident enough to get involved in things in life that interest me” was the strongest item, although the strength stability coefficient (0.36) suggested strength should be interpreted with caution. The average edge weight was 0.02; however, stronger edges were identified.LimitationsThe network showed low stability, possibly due to sample heterogeneity. Future work could incorporate demographic variables, such as time since BD diagnosis or stage of personal recovery, into network estimation.ConclusionsNetwork analysis can be applied to personal recovery, not only clinical symptoms of BD. Clinical applications could include tailoring recovery‐focussed therapies towards encouraging important aspects of recovery, such as feeling confident to get involved with life.

Published: October 2024

AbstractAqueous alkali‐ion batteries are gaining traction as a low‐cost, sustainable alternative to conventional organic lithium‐ion batteries. However, the rapid degradation of commonly used electrode materials, such as Prussian Blue Analogs and carbonyl‐based organic compounds, continues to challenge the economic viability of these devices. While stability issues can be addressed by employing highly concentrated water‐in‐salt electrolytes, this approach often requires expensive and, in many cases, fluorinated salts. Here, we show that replacing monovalent K+ ions with divalent Ca2+ ions in the electrolyte significantly enhances the stability of both a copper hexacyanoferrate cathode and a polyimide anode. These findings have direct implications for developing an optimized aqueous Ca‐ion battery that demonstrates exceptional fast‐charging capabilities and ultra‐long cycle life and points toward applying Ca‐based batteries for large‐scale energy storage.

AbstractManaging feral water buffalo in the Northern Territory is a formidable challenge. As an introduced species, buffalo are associated with a myriad of biosecurity, economic, cultural and environmental issues ranging from overgrazing, decreased water quality, disease vectors to the destruction of cultural assets. Nevertheless, the buffalo are also a harvestable resource that can support economic development of the region. To mitigate some of the biosecurity, economic, cultural and environmental risks they pose and manage buffalo effectively, we need a detailed understanding of their spatial and behavioural ecology. However, several factors make understanding how best to manage the dense populations of wild individuals challenging as buffalo inhabit remote areas with limited infrastructure and accessibility and their large size and often aggressive nature can make them difficult to observe in otherwise inaccessible areas. GPS tracking allows for high‐frequency data collection and surveillance of individual buffalo. Here, we investigated how the different seasonal periods of a Northern Territory floodplain area shaped patterns of habitat use for 17 buffalo tracked over 16 months. We found in the dry season, buffalo space use is restricted, and the size of home ranges are significantly smaller than in the wet season. During the wet season, buffalo expand their home range area as well as their social encounter area with other buffalo. These differences in their space use and social patterns suggest that increased disease surveillance may be needed for the wet season when buffalo are more likely to share space and interact. During the dry season, however, buffalo movement is more predictable and restricted, suggesting greater optimisation opportunities for buffalo management. Results from these models can be used by land holders, Traditional Owners and wildlife managers to make evidence‐based decisions to improve buffalo management with respect to disease risk, sustainable harvest and damage to environmental and cultural assets.

ABSTRACTThe foraging strategies of sympatric ungulates with similar ecological niches are important for understanding ecological niche differentiation, resource utilization, competition, and coexistence and for understanding the ecological impacts on plant communities in the ecosystem. The behavior of the wapiti (Cervus elaphus) and Siberian roe deer (Capreolus pygargus) foraging on Japanese yew (Taxus cuspidata) has affected its succession and renewal in the northeastern forests of China, which has become an urgent problem for the relevant departments. This study analyzed the foraging strategies of the wapiti and Siberian roe deer on Japanese yew from July 2021 to January 2024 using field investigations and infrared camera monitoring in the Muling National Nature Reserve, Heilongjiang Province, China. It was found that the wapiti and Siberian roe deer have different foraging strategies in terms of time, space, and behavior. Temporally, they both preferred to forage for the saplings of the Japanese yew during the winter season, the degree of overlap in foraging rhythms was medium (Dhat1 = 0.67), and the diurnal foraging activity index (DRAI) of the wapiti was larger than that of the Siberian roe deer. Spatially, the suitable foraging habitat of the Siberian roe deer was twice that of the wapiti, and their overlap was low in the location and direction of saplings and the distance of the seed tree. Behaviorally, the foraging intensity of the wapiti was high, and that of Siberian roe deer was low. Foraging reduced the average primary branch height, number of new branches, and length of lateral branches of saplings, and the influence of the wapiti was significantly greater than that of the Siberian roe deer. This study provides a scientific basis for solving the conservation and management problems of the deer animals foraging on Japanese yew and contributes to further understanding of the competition‐coexistence mechanism of sympatric species.

ABSTRACTHarmful algal blooms (HABs) often occur in estuaries due to their unique environmental heterogeneity, posing significant environmental and human health risks. However, there is limited understanding of the community composition and community‐level change points (thresholds) of harmful microalgae in subtropical estuaries. This study explored harmful microalgae community structure and thresholds in the Dafengjiang River estuary using a metabarcoding approach. The results revealed 63 harmful microalgae species, and major species included Guinardia flaccida, Prorocentrum cordatum, Thalassiosira punctigera, Pseudo‐nitzschia galaxiae and T. gravida. Nonparametric change‐point analysis and threshold indicator taxa analysis (TITAN) showed threshold responses of harmful microalgae community structure to ammonium (57.5–60 μg·L−1), total phosphorus (27.8–28.5 μg·L−1) and dissolved inorganic phosphorus (14.5–28 μg·L−1) along the salinity gradient. Wider environmental thresholds were also found in hypersaline areas. Additionally, Pyrodinium bahamense, Pfiesteria piscicida, Skeletonema tropicum and T. punctigera were sensitive to environmental changes and thus could be used as bioindicators. Overall, our study unveiled diverse abrupt transitions of harmful microalgal communities, providing a risk assessment for human health and ecological safety in subtropical estuary ecosystems.

AbstractDion‐Jacobson‐type layered perovskite compounds A′SmNb2O7 (A′=Rb, K, Na, Li, H) were synthesized using solid‐state and ion‐exchange methods. While the parent solid‐state product RbSmNb2O7, has previously been studied, the ion‐exchanged compounds were obtained and studied for the first time. The phase and chemical purity of the compounds were confirmed by X‐ray diffraction (XRD) and energy‐dispersive X‐ray spectroscopy (EDX). The crystal structures of RbSmNb2O7 (I2 cm, a=0.54356(1) nm, b=0.53935(1) nm, c=2.1891(5) nm), KSmNb2O7 (I2 cm, a=0.53660(7) nm, b=0.54481(6) nm, c=2.1527(1) nm) and LiSmNb2O7 (B2 cm, a=0.54546(4) nm, b=0.53567(4) nm, c=2.04582(5) nm) were refined using the Rietveld method. Polyhedral distortions in these structures have been studied in detail. The thermal behavior of the compounds has been determined using differential thermal analysis (DTA), revealing that A′=Na, Li and H compounds are metastable hydrates, while A′=Rb and K compounds are stable. The optical band gap, valence band edge, and conduction band edge potentials of the compounds obtained were calculated using diffuse reflection spectroscopy data. A photocatalytic experiment was performed on the degradation of methylene blue under ultraviolet light. All of the samples obtained showed some asctivity in the reaction of dye photooxidation.

Published: October 2024

AbstractA photo‐induced two/three‐component radical difluoroethylation or monofluoromethyl sulfonylation of 2‐amino aryl ethynes was smoothly finished, which gave a series of difluoroethyl or monofluoromethyl sulfonyl seven‐membered N‐heterocycles. The two radical systems featured simple/mild reaction conditions, good substrate scopes, and excellent E/Z selectivity. In addition, various radical intermediates were successfully detected by HRMS to explore the reaction process. Single‐crystal X‐ray diffraction and scaled‐up experiments examined the product scaffold and application of this cyclization system.

Published: October 2024

AbstractMethods to afford 2‐aminobenzothiazoles often involve the use of o‐aminothiophenols or aniline‐typed precursors. Herein we describe a method to furnish 2‐aminobenzothiazoles through the cyclization of o‐chloronitrobenzenes and aryl isothiocyanates with the assistance of elemental sulfur. From the perspective of step economy, our strategy allows for the direct use of nitroarene precursors without further reduction to anilines. The scope of the reaction with respect to both substrates was investigated, and it was found that electronic properties of the aryl isothiocyanate was important for obtaining acceptable yields.
Ambient Pressure Hydroformylation – A Key Step to Meso‐Alkyl BODIPYs
Authors: Miller Lukas , Bauer Felix , Breit Bernhard 
Published: October 2024

AbstractHerein, a highly efficient five‐step reaction sequence to meso‐alkyl BODIPYs is presented. In our previous work, the hydroformylation of terminal alkenes was used to generate an aldehyde from an alkene via rhodium catalysis and use them in a subsequent tandem reaction to obtain BODIPY dyes. However, the use of higher pressures and therefore autoclaves as well as their necessary equipment might limit others to use this method. The refined approach in this work employs ambient pressure hydroformylation, done in a simple Schlenk tube and using a CO/H2 balloon, as key step towards an easier meso‐alkyl BODIPY synthesis. Additionally, the use of MTBE instead of chloroform as reaction solvent results in a greener approach. Readily available and easily synthesizable alkenes as well as different pyrrole building blocks can be used to extend the range of known alkyl‐BODIPYs. The synthesis of 23 derivatives with overall yields of up to 67 % demonstrates the wide applicability and advantages of the refined method.
Recent ice‐contact delta formation in front of Pio XI glacier controls sedimentary processes in Eyre Fjord, Patagonia

Published: October 2024

AbstractPio XI Glacier (49°S) is the largest and one of the very few advancing glaciers in Patagonia. Satellite data indicate that the main glacier terminus transitioned from calving to land‐based around 2010, effectively resulting in the formation of an ice‐contact delta at the head of Eyre Fjord. Here, we investigate how this ice‐contact delta formation affected sediment transport processes in Eyre Fjord. Sediment cores and seismic profiles collected along the fjord provide evidence for a relatively abrupt increase in the number and magnitude of turbidity currents, coeval with the formation of the ice‐contact delta. This observation is supported by modern summer hydrographic observations and bathymetric data. We posit that the ice‐contact delta formation resulted in sediment input being concentrated at specific subaerial locations across the fjord head, which favoured the development of plume‐triggered turbidity currents. This suggests that a sudden increase in turbidite thickness in fjord sediment records could represent ice‐contact delta development at fjord heads.

ABSTRACTBiomass and biowaste resources can be used to create self‐doped carbon with a distinctive microstructure. Using an economical and environmentally friendly method to create heteroatom‐doped carbon electrode materials with excellent electrochemical performance has attracted much attention in the energy storage industry. A novel facile two‐step, low‐cost, and eco‐friendly synthesis method for Colocasia esculenta peels has been developed to manufacture activated carbon (CEPAC) and used as an electrode material for supercapacitor application. The CEPAC 1:1 displayed a high specific surface area of 910 m2/g with oxygen‐heteroatom polar sites in the carbon network. A specific capacitance of 525.3 F/g was recorded in the three‐electrode system using a 3 M KOH solution. The assembled symmetric cell delivered an impressive specific capacitance of 98.7 F/g at 1 A/g while maintaining 98.4% of the initially recorded capacitance after 10 000 charge–discharge cycles. These results present a promising low‐cost and simple processing route for synthesizing electrode materials with superior surface properties for high‐performance supercapacitors.

Published: October 2024

ABSTRACTTo enhance the electrochemical performance of the Zn solid‐state battery, we introduce simonkolleite as a novel anode material. With oxygen vacancies on its surface, simonkolleite exhibits both electrical and chemical activity; these vacancies serve as n‐type donors, significantly improving the material's conductivity. In this research, simonkolleite is synthesized using a straightforward and cost‐effective method and employed as the anode. The all‐solid‐state Zn battery combines the simonkolleite anode, sodium silicate (SS) electrolyte, and graphite film (GF) cathode. Our battery configuration (simonkolleite/Ingot SS/GF) achieves a high 1280 mAh g−1 capacity and demonstrates improved cyclic stability. The large‐scale module battery can also power a motor‐fan unit for 1 h and 19 min.
Development of antioxidant‐rich curd fortified with encapsulated beetroot (Beta vulgaris L.) peel extract powder
Authors: Pandey Surabhi , Singh Anurag 
Published: October 2024

AbstractA curd with enhanced antioxidants was developed adding nanoencapsulated Beetroot Peel Extract Powder (BPEM) @ 1.0 % w/v of milk. Beetroot peel extract‐based powder was produced by the spray drying technique using maltodextrin and guar gum as coating agents. The prepared samples were tested for sensory characteristics, textural properties, antioxidant content, and proximate characteristics. The results show that the sensorial characteristics of the fortified curd were improved as compared to the control one. The incorporation of nanoencapsulated BPEM resulted in a softer and more delicate texture of the fortified curd (Hardness [N]: 195 ± 10.6) as compared to control (Hardness [N]: 335 ± 3.53). The physicochemical properties of antioxidant‐enhanced curd resulted in 87.4 ± 0.7% moisture, 2.2 ± 0.35% fat, 4.76 ± 0.04% protein, 14.6 ± 0.35% total solids, and 6.59 ± 0.10% carbohydrate. Furthermore, the addition of beetroot peel extract‐based powder showed a higher antioxidant (76.6 ± 0.72% DPPH inhibition) and phenolic content (85.7 ± 0.25 μg Gallic acid equivalent [GAE]/mL) in the developed curd as compared to the control (54 ± 0.66% DPPH inhibition and 59.9 ± 0.75 μg GAE/mL total phenolic content).
Mechanical Coupling Effect on Tide‐Induced Fluctuations in a Multilayer Aquifer System
Authors: Cuello Julián E. , Guarracino Luis 
Published: October 2024

ABSTRACTWe present a new analytical solution to study the mechanical coupling on tidal‐induced head fluctuations in a coastal aquifer system. The conceptual model consists of two overlying confined units that extend infinitely under the sea. The proposed model assumes that the tidal fluctuations in the overlying aquifer are described by the classical equation derived by van der Kamp. For the underlying aquifer, a closed form analytical expression is derived by solving a boundary value problem that considers the loading effect produced by the overlying unit. The amplitude and phase lag of the underlying aquifer depend on both the specific storage and the thickness of the overlying unit. A parametric study shows that the mechanical coupling effect can be important for both large values of specific storage and thickness of the overlying aquifer.
Forest Dieback Alters Nutrient Pathways in a Temperate Headwater Catchment

ABSTRACTForested headwater catchments ensure good water quality for downstream ecosystems and human consumption. Climate change and the exacerbating likelihood of extreme events elevate the risk of severe forest dieback. However, the effects of forest dieback on the quantity and quality of stream water are not fully understood. Here, we analyse high‐frequency observations of discharge, electrical conductivity (EC), dissolved organic carbon (DOC) and nitrate (NO3N) obtained before, during and after a drought‐induced forest dieback in a headwater stream in the German Harz Mountains. We focus on the characteristics of concentration‐discharge (C‐Q) relationships at the scale of runoff events to assess the effects of forest dieback on the sources, mobilisation and pathways of EC, DOC and NO3N. When comparing pre‐ and post‐dieback conditions, we found a significant increase in runoff efficiency and a doubling of DOC loads exported from the catchment, while DOC concentrations increased only moderately and their C‐Q patterns did not change. EC exhibit no changes in concentrations but a steepening of C‐Q dilution patterns. We explain these findings with a dieback‐induced decrease in evapotranspiration, which leads to more intensive drainage of the upper organic soil layers in the riparian zone. In contrast, we observed a strong increase in NO3N concentrations and fluxes by a factor of ~5, while C‐Q patterns at the event scale changed from enrichment to dilution. We argue that the dieback led to an excess of NO3N on the hillslopes that connect to the stream via surficial flowpaths. In this way, NO3N bypasses the riparian zone, reducing the catchment's efficiency in attenuating this nutrient. Our study emphasises the pivotal role of riparian zones in mediating water quality in headwater streams. Different configurations of the riparian zone and its connection to the hillslopes and the stream network may be a missing piece in explaining differences in water quality responses of catchments to forest dieback.
Characteristics and outcomes of infants admitted to a parent–infant inpatient psychiatric unit: A pilot study
Authors: Hill Rebecca , Coventry Liz , Prior Meg 
Published: October 2024

AbstractInpatient parent–infant psychiatric units (PIUs) are considered “gold standard” for treating maternal mental illness, with well‐documented positive outcomes for mothers. However, little research addresses outcomes for infants in these units, who often face significant developmental and socio‐emotional adversity. This pilot study aimed to evaluate the characteristics and progress of an Australian PIU population, focusing on the impact of PIU admission on infant outcomes. Over 3 months, 31 consecutively admitted mother–infant pairs (dyads) were assessed through interviews, observations, and standardized measures to evaluate maternal and infant characteristics and progress from admission to discharge. Maternal well‐being and the mother–infant relationship improved. Infants exhibited high levels of physical (29%) and developmental concerns (80.6%). 22.6% receiving an Axis I infant mental health diagnosis. Infant socio‐emotional responsiveness improved significantly, as measured by the modified Alarm‐Distress Baby Scale, indicating a positive impact of PIU admission. The small sample size and reliance on clinician‐observed measures limit the generalizability of the findings. PIU infants are particularly vulnerable, and PIU admission may ameliorate socio‐emotional responsiveness. Further research with larger samples and extended follow‐up is needed to determine the most effective intervention strategies during and after PIU admission to maximize benefits for these infants.
