AbstractFabrication and characterization of solar cells based on multicrystalline silicon (mc‐Si) thin films are described and synthesized from low‐cost soda‐lime glass (SLG). The aluminothermic redox reaction of the silicon oxide in SLG during low‐temperature annealing at 600 – 650 °C leads to an mc‐Si thin film with large grains of lateral dimensions in the millimeter range, and moderate p‐type conductivity with an average Al acceptor concentration between 5 × 1016 and 1.2 × 1017 cm−3 in the bulk. A residual composite layer of mainly alumina and unreacted Al forms beneath the mc‐Si thin film as the second product of the crystalline silicon synthesis (CSS) process, which can be used as rear contact in a vertical solar cell design. The mc‐Si absorber (≈10 µm) is thin enough that the diffusion length given by a minority carrier lifetime of ≈1 µs exceeds the path length to the top contact several times. Homojunction and heterojunction diodes have been fabricated on the mc‐Si thin films and show great potential of CSS for the realization of high‐performance solar cells.

Authors: Mason Alexander F , Wickham Shelley FJ , Baker Matthew AB 
Published: September 2024

AbstractDroplet interface bilayers (DIBs) offer a controlled lipid environment for studying membrane‐bound processes, with applications in artificial cells, biosensing, and biophysics. Current DIB fabrication faces challenges due to time‐consuming processes and specialized equipment, limiting scale‐up and hindering statistical significance in single‐molecule assays. This research introduces “DIB‐BOT,” an open‐source solution combining a nanoinjector and a 3D printer. DIB‐BOT enables rapid, reproducible DIB fabrication, overcoming manual limitations. Using off‐the‐shelf components, DIB‐BOT ensures high spatial reproducibility, minimal user input, and scalable experiments. The system's utility is demonstrated through pairwise droplet assembly and a fluorescence plate‐reader assay. Compared to manual fabrication, DIB‐BOT shows a 10‐fold reduction in droplet volume error, a threefold reduction in positional error, and 100% droplet yield. This method lowers entry barriers to DIB research, expanding its applications and enhancing data quality.
Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Authors: Yersin Hartmut , Monkowius Uwe 
Published: September 2024

This review focuses on thermally activated delayed fluorescence (TADF). Photophysical properties of Cu(I) complexes and unique organic molecules are addressed. Investigations, based on temperature‐dependent emission studies, micro‐ to femto‐second time‐resolved spectroscopy investigations, quantum mechanical considerations, state‐of‐art calculations, and organic light‐emitting diodes (OLED) device studies, address exciton harvesting mechanisms and photophysical impact of the energy gap ΔE(S1–T1) and spin‐orbit coupling (SOC). We disclose relationship between (i) ΔE(S1–T1) and transition rate k(S1–S0); (ii) SOC, phosphorescence, and intersystem crossing (ISC); (iii) internal/external rigidity, luminescence quantum yield, excitation self‐trapping, and concentration quenching; (iv) environment polarity and state energy tuning, as well as (v) SOC and combined ambient‐temperature TADF/phosphorescence, zero‐field splitting, and spin‐lattice relaxation (at T = 1.2 K). These studies guide us to milestone Cu(I) complexes. Moreover, we demonstrate that fast ISC in organic molecules requires state mixing with an additional, energetically close triplet state. Thus, a guide structure for unique organic TADF molecules with ultra‐fast ISC and reverse‐ISC rates (>109 s−1) combined with ΔE(S1–T1)<10 cm−1 (<1 meV) is presented allowing for ultra‐fast singlet‐triplet equilibrated fluorescence with sub‐microsecond decay. First OLEDs fabricated show high external quantum efficiency of ≈19%. Based on this breakthrough material class, a new exciton harvesting mechanism, the direct singlet harvesting (DSH), is presented.

Published: September 2024

AbstractThe commercialization of zinc metal batteries (ZMBs) for large‐scale energy storage is hindered by challenges such as dendrite formation, the hydrogen evolution reaction (HER), and passivation/corrosion, which lead to poor stability of zinc metal anodes. HER is a primary contributor to this instability, and despite efforts to enhance ZMB cyclability, a significant knowledge gap remains regarding the origin of HER in these systems. Prior works, based primarily on theoretical calculations with minimal experimental support, suggest that HER originates from Zn2⁺‐solvated water. For the first time, by employing scanning electrochemical microscopy (SECM), and electrochemical mass spectrometry (ECMS), in real‐time the inherently intertwined nature of Zn electrodeposition and H₂ liberation is revealed, both exhibiting the same onset potential in voltammetry. The findings show that water molecules surrounding Zn2⁺ ions undergo reduction simultaneously during Zn2⁺ deposition. Additionally, ECMS conducted under chronopotentiometric/galvanostatic conditions at battery‐relevant current densities elucidates why elevated electrolyte concentrations enhance the prolonged cyclability of ZMBs. Understanding the origin of HER opens avenues for developing high‐performance, reliable aqueous ZMBs, addressing key challenges in their commercialization and advancing their technological capabilities.

Published: September 2024

AbstractSilicon (Si)‐based anodes hold great potential for next‐generation lithium‐ion batteries (LIBs) due to their exceptional theoretical capacity. However, their practical application is hindered by the notably substantial volume expansion and unstable electrode/electrolyte interfaces during cycling, leading to rapid capacity degradation. To address these challenges, we have engineered a porous nitrogen/sulfur co‐doped carbon layer (CBPOD) to uniformly encapsulate Si, providing a multifunctional protective coating. This innovative design effectively passivates the electrode/electrolyte interface and mitigates the volumetric expansion of Si. The N/S co‐doping framework significantly enhances electronic and ionic conductivity. Furthermore, the carbonization process augments the elastic modulus of CBPOD and reconstructs the Si‐CBPOD interface, facilitating the formation of robust chemical bonds. These features collectively contribute to the high performance of the Si‐CBPOD anodes, which demonstrate a high reversible capacity of 1110.8 mAh g−1 after 1000 cycles at 4 A g−1 and an energy density of 574 Wh kg−1 with a capacity retention of over 75.6% after 300 cycles at 0.2 C. This study underscores the substantial potential of the CBPOD protective layer in enhancing the performance of Si anodes, providing a pathway for the development of composite materials with superior volumetric energy density and prolonged cyclic stability, thereby advancing high‐performance LIBs.

Published: September 2024

AbstractBackgroundInformation on worker occupation and industry is critical to understanding the occupational risks of heat‐related illness (HRI), yet few syndromic surveillance systems capture these key data elements. This study evaluates the work data reported through Washington syndromic surveillance for its utility in characterizing HRI ED visits by industry and occupation.MethodsStandard industry and occupation codes were assigned to employer name and occupation descriptions reported in Washington ED visit records maintained within the state's syndromic surveillance system, for visits involving HRI in 2020–2022. HRI ED visits involving workplace heat exposure were identified based on discharge diagnoses or on keywords in the triage note or chief complaint fields. HRI ED visits were summarized by patient characteristics, and visit rates were calculated by industry and occupation.ResultsEmployer name or occupation descriptions were reported in 21.5% of HRI ED records among patients age 16 and older, and in 41.2% of records with mention of heat exposure at work. Twice as many records were classified for industry as for occupation. Agriculture, forestry, fishing, and hunting and transportation and warehousing had the highest rates of HRI ED visits. Specific industries with the highest rates included support activities for agriculture and forestry, the postal service, and fruit and vegetable preserving and specialty food manufacturing.ConclusionSyndromic surveillance data are a valuable source of occupational health surveillance information when work characteristics are reported, enhancing our understanding of the occupational risks of injuries and illnesses.

AbstractA central goal of biological anthropology is connecting environmental variation to differences in host physiology, biology, health, and evolution. The microbiome represents a valuable pathway for studying how variation in host environments impacts health outcomes. While there are many resources for learning about methods related to microbiome sample collection, laboratory analyses, and genetic sequencing, there are fewer dedicated to helping researchers navigate the dense portfolio of bioinformatics and statistical approaches for analyzing microbiome data. Those that do exist are rarely related to questions in biological anthropology and instead are often focused on human biomedicine. To address this gap, we expand on existing tutorials and provide a “road map” to aid biological anthropologists in understanding, selecting, and deploying the data analysis and visualization methods that are most appropriate for their specific research questions. Leveraging an existing dataset of fecal samples and survey data collected from wild geladas living in Simien Mountains National Park in Ethiopia (Baniel et al., 2021), this paper guides researchers toward answering three questions related to variation in the gut microbiome across host and environmental factors. By providing explanations, examples, and a reproducible workflow for different analytic methods, we move beyond the theoretical benefits of considering the microbiome within anthropological research and instead present researchers with a guide for applying microbiome science to their work. This paper makes microbiome science more accessible to biological anthropologists and paves the way for continued research into the microbiome's role in the ecology, evolution, and health of human and non‐human primates.

Published: September 2024

AbstractPurely organic molecules exhibiting near‐infrared (NIR) emission possess considerable potential for applications in both biological and optoelectronic technological domains, owing to their inherent advantages such as cost‐effectiveness, biocompatibility, and facile chemical modifiability. However, the repertoire of such molecules with emission peaks exceeding 750 nm and concurrently demonstrating high photoluminescence quantum efficiency (PLQE) remains relatively scarce due to the energy gap law. Herein, we report two open‐shell NIR radical emitters, denoted as DMNA‐Cz‐BTM and DMNA‐PyID‐BTM, achieved through the strategic integration of a donor group (DMNA) onto the Cz‐BTM and PyID‐BTM frameworks, respectively. We found that the donor‐acceptor molecular structure allows the two designed radical emitters to exhibit a charge‐transfer excited state and spatially separated electron and hole levels with non‐bonding characteristics. Thus, the high‐frequency vibrations are effectively suppressed. Besides, the reduction of low‐frequency vibrations is observed. Collectively, the non‐radiative decay channel is significantly suppressed, leading to exceptional NIR PLQE values. Specifically, DMNA‐Cz‐BTM manifests an emission peak at 758 nm alongside a PLQE of 55 %, whereas DMNA‐PyID‐BTM exhibits an emission peak at 778 nm with a PLQE of 66 %. Notably, these represent the pinnacle of PLQE among metal‐free organic NIR emitters with emission peaks surpassing 750 nm.

Published: September 2024

SummaryWe report a case of rebounding severe methaemoglobinaemia secondary to sodium nitrite ingestion, despite several administrations of methylene blue. The patient's clinical course was characterised by a series of alternating improvements and deteriorations and proved challenging for treating clinicians. On discussion with poisoning experts, it was hypothesised that a small amount of sodium nitrite remained in the gastrointestinal tract leading to prolonged absorption of the causative agent. Methaemoglobin levels returned to normal following the administration of multi‐dose activated charcoal via a nasogastric tube 30 h after the initial presentation to hospital.

ObjectiveEpitope spreading (ES), involving autoantibodies, plays a crucial role in the development and persistence of autoimmune reactions in various autoimmune diseases. This study aimed to investigate the relationship between ES of anti–RNA polymerase III (RNAP III) antibodies (ARAs) and the clinical manifestations of systemic sclerosis (SSc).MethodsWe investigated whether intermolecular ES occurs in the subunits of the RNAP III complex and whether intramolecular ES targets the major antigen, RNA polymerase III subunit A (RPC1), in patients with SSc. To achieve this, we synthesized 17 full‐length subunit proteins of the RNAP III complex and 5 truncated forms of RPC1 in vitro using a wheat germ cell‐free translation system. Subsequently, we prepared antigen‐binding plates and measured autoantibodies in the serum of patients with SSc.ResultsAutoantibodies against different RNAP III complex subunits were found in patients who were ARA‐positive with SSc. The intermolecular ES indicators significantly correlated with the modified Rodnan skin thickness score (mRSS) and surfactant protein‐D, a biomarker of interstitial lung disease. However, the extent of disease on high‐resolution computed tomography or pulmonary function tests did not show any significant correlation. Intramolecular ES indicator against RPC1 were significantly correlated with mRSS and renal crisis. Furthermore, longitudinal assessment of ES in RNAP III complex subunits correlated with mRSS and exhibited potential as a disease activity biomarker.ConclusionOur findings indicate a correlation between ES levels and the severity of skin sclerosis or the risk of other complications in SSc. This study suggests that measuring ES in SSc serves as a novel biomarker for disease activity.image

Authors: Li Chenxi , He Wen‐Qiang 
Published: September 2024

AbstractThis study aims to assess the prevalence of Autism Spectrum Disorder (ASD) and its treatment. The study population was children aged 3–17 years with information on current ASD from National Survey of Children's Health, 2016–2022. Analysis of treatment was also conducted within the population of children with a current ASD diagnosis. A multivariate log‐binomial regression model was used to assess the change of current ASD prevalence and ASD treatment by two study period (prior to COVID‐19 pandemic: 2016–2019; during COVID‐19 pandemic: 2020–22) and sociodemographic information. Compared to the current ASD at 2.5% in 2016, it increased to 3.6% in 2022. The treatment has decreased from 70.5% in 2016 to 61.6% in 2022 for any treatment and from 27.2% in 2016 to 20.4% in 2022 for medication treatment. Compared to children from 2016–2019, children from the following group were more likely to have ASD diagnosis during the pandemic (2020–2022), including those aged 3–5 years (aPR = 1.66, 95%CI 1.29–2.13), non‐Hispanic white children, children from family with above national family income, and those with private insurance. However, medication treatment almost halved during the pandemic for non‐Hispanic black children (aPR = 0.49, 95%CI 0.26–0.93) and children born overseas. In conclusion, higher prevalence of ASD might indicate a better awareness of ASD. The reduction in treatment correlates to the health service disruption caused by the pandemic, highlighting the needs of policy efforts to improve treatment for ASD.

AbstractThe peptide CIGB‐210 inhibits HIV replication, inducing a rearrangement of vimentin intermediate filaments. The assessment of the in vitro serum and plasma stability of this peptide is important to develop an optimal pharmacological formulation. A half‐life of 17.68 ± 0.59 min was calculated for CIGB‐210 in human serum by reverse‐phase high‐performance liquid chromatography (HPLC) and mass spectrometry (MS). Eight metabolites of CIGB‐210 were identified with this methodology, all of them lacking the N‐terminal moiety. A previously developed CIGB‐210 in‐house competitive ELISA was used to compare the stability of CIGB‐210 derivatives containing either D‐amino acids, acetylation at the N‐terminus, or both modifications. The half‐life of CIGB‐210 in serum was five times higher when measured by ELISA than by HPLC/MS, and twice higher in plasma as compared to serum. The substitution of D‐asparagine on position 6 doubled the half‐life, while D‐amino acids on positions 8 and 9 did not improve the stability. The acetylation of the N‐terminus resulted in a 24‐fold more stable peptide in plasma. The positive effect of N‐terminal acetylation on CIGB‐210 serum stability was confirmed by the HPLC/MS method, as the half‐life of the peptide was not reached after 2 h of incubation, which represents more than a 6.8‐fold increase in the half‐life with respect to the original peptide.
‘Yoga is a way of life’ exploring experiences of yoga as a treatment for substance use: An interpretative phenomenological analysis
Authors: Miller Nicole M. 
Published: September 2024

AbstractIntroductionYoga is a form of complementary medicine for substance use disorder (SUD). Randomised controlled trials involving yoga for the treatment of SUD have found that yoga practice reduces the risk of relapse and improves mood and well‐being for people undergoing treatment for SUD; however, the lived experience of yoga practice involving the benefits of reducing SUD is unknown. The aim of this study was to examine the in‐depth experience of yoga to inform the treatment of SUD.MethodsFive semi‐structured interviews explored experiences of yoga among people with a prior history of substance use. Four out of the five participants reported prior use of alcohol, and one reported the use of ‘GBL’ and methamphetamine. Data were analysed using interpretative phenomenological analysis.ResultsThe analysis resulted in three final Superordinate themes: (1) growing awareness of the body, mind and emotions; (2) yoga opens a positive way of life; and (3) blending the worlds of yoga and 12‐step recovery. Yoga was reported to enhance awareness of muscle tension, reduce physical stress, increase positive emotions and build tolerance to negative emotions. The integration of the eight‐limb philosophy of yoga, notably withdrawing of the senses, helped combat internal cues and triggers (negative thoughts and emotions) for relapse. Yoga was reported to be compatible with an abstinence‐based lifestyle found in 12‐step mutual aid programmes and helped extend social networks to support long‐term abstinence.ConclusionsThe experience of integrating the eight‐limb philosophy to support abstinence and the asana practice helped participants to reduce cue reactivity. Yoga appeared to enhance interoceptive awareness, which is useful for reducing physical stress related to triggers for relapse, making yogic practice a valuable tool to integrate within mainstream group and individual relapse prevention programmes. Therefore, programmes and health policymakers may want to consider treatments that integrate yogic practices to enhance and support long‐term abstinence for SUD.
Exploring AI technology and consumer behavior in retail interactions

Published: September 2024

AbstractThis research systematically reviews artificial intelligence (AI) effects in customer‐interfacing retail applications based on an ecosystem value co‐creation framework. We conduct a bibliometric and conceptual mapping analysis study, focusing on AI‐related implications for consumers' and other stakeholders' well‐being, social interaction, and societal welfare. A co‐citation network visualization of critical AI journal articles is generated, and a network visualization of AI keyword relationships and clustered topic areas is presented and discussed, along with a conceptual map of the relationships between key concepts and substantive AI themes. In an ecosystem context, the multidisciplinary‐based bibliometric and conceptual mapping findings of our analysis reflect the need to focus not only on the positive and negative effects on stakeholder well‐being, social interaction, and societal welfare but also on how effects created in one of these levels impact the value created in the other social layers. Furthermore, the interdisciplinary characteristics necessary in effectively implementing and managing AI technologies emphasize the need for collaboration among multiple organizational departments, technology partners, and other members of the business ecosystem. The findings of this research contribute to assessing both the positive and negative effects of AI and allow for its implementation in a way that is helpful to organizations, employees, consumers, and society. This study should also help managers decide which situations are best suited for using AI and which are not.
