AbstractAdapting the coordination environment to influence the electronic configuration of active sites represents an efficient approach for improving the photocatalytic performance of the CO2 reduction reaction (CO2RR) but how to execute it precisely remains challenging. Herein, heteroatom‐substitution in Ni‐porphyrin to break the coordination symmetry of Ni center is proposed to be an effective solution. Based on this, two symmetry‐breaking Ni‐porphyrins, namely Ni(Cl)ON3Por and Ni(Cl)SN3Por, are designed and successfully prepared. By theoretical calculation, it is found that symmetry‐breaking efficiently regulates the 3d orbital energy levels of Ni center. Furthermore, experimental and theoretical findings jointly revealed that coordination symmetry‐breaking of Ni‐porphyrins facilitates the generation of highly reactive NiI species during the catalytic process, effectively stabilizing and reducing the energy barrier of formation of the key *COOH intermediate. As a result, Ni(Cl)ON3Por and Ni(Cl)SN3Por gave CO production rates of 24.7 and 38.8 mmol g−1 h−1 as well as selectivity toward CO of 94.0% and 96.4%, respectively, outperforming that of symmetric NiN4Por (CO production rate of 6.6 mmol g−1 h−1 and selectivity of 82.8%). These findings offer microscopic insights into how to modulate the catalytic activity by precisely tuning the coordination environment of active sites and rational design of competent catalyst for CO2RR photocatalysis.

AbstractDespite the rapid development in the performances of organic solar cells (OSCs), high‐performance OSC modules based on green printing are still limited. The severe Coffee‐ring effect (CRE) is considered to be the primary reason for the nonuniform distribution of active layer films. To solve this key printing problem, the cosolvent strategy is presented to deposit the active layer films. The guest solvent Mesitylene with a higher boiling point and a lower surface tension is incorporated into the host solvent o‐XY to optimize the rheological properties, such as surface tension and viscosity of the active layer solutions. And the synergistic effect of inward Marangoni flow generation and solution thickening caused by the cosolvent strategy can effectively restrain CRE, resulting in highly homogeneous large‐area active layer films. In addition, the optimized crystallization and phase separation of active layer films effectively accelerate the charge transport and exciton dissociation of devices. Consequently, based on PM6:BTP‐eC9 system, the device prepared with the co‐solvent strategy shows the a power conversion efficiency of 17.80%. Moreover, as the effective area scales to 1 and 16.94 cm2, the recorded performances are altered to 16.71% and 14.58%. This study provides a universal pathway for the development of green‐printed high‐efficiency organic photovoltaics.

AbstractTransition metal oxides, especially bimetal oxides, are considered as one of the most promising anode materials for high‐performance lithium‐ion batteries (LIBs) due to their ultra‐high theoretical capacity. However, it is difficult to achieve fast charging at high rates due to the issues of poor electrical conductivity, large volume expansion, and poor reaction kinetics. The design of advanced nanostructured anode materials is very important to boost lithium storage performance. Herein, the multi‐hierarchical heterostructure material NiCo2O4/ZnCo2O4/Carbon Cloth (NCO/ZCO/CC) including carbon cloth substrate, ZnCo2O4 nanosheets, and NiCo2O4 nanowires is prepared as a binder‐free anode for LIBs. Benefiting from the special hierarchical nanostructure and the synergistic interaction of the component, the as‐prepared NCO/ZCO/CC anode material exhibits good electrical conductivity, structural stability, and electrochemical kinetics, which can provide a high reversible areal capacity of 2.55 mAh cm−2 at 2 mA cm−2 after 200 cycles. At a high current density of 5 mA cm−2, the NCO/ZCO/CC electrode only takes about 20 min to fully charge and it can still reach a capacity of 1.50 mAh cm−2 with a capacity retention of 86.2% after 400 cycles, revealing the potential for fast charging at high rates.

Published: February 2024

AbstractEnergy storage devices with liquid‐metal electrodes have attracted interest in recent years due to their potential for mechanical resilience, self‐healing, dendrite‐free operation, and fast reaction kinetics. Gallium alloys like Eutectic Gallium Indium (EGaIn) are appealing due to their low melting point and high theoretical specific capacity. However, EGaIn electrodes are unstable in highly alkaline electrolytes due to Gallium oxide dissolution. In this letter, this bottleneck is addressed by introducing chemically stable films in which nanoscale droplets of EGaIn are coated with trace amounts of graphene oxide (GO). It is demonstrated that a GO to EGaIn weight ratio as low as 0.01 provides enough protection for a thin film formed by GO@EGaIn nanocomposite against significantly acidic or alkaline environments (pH 1‐14). It is shown that GO coating significantly enhances the surface stability in such environments, thus improving the energy storage capacity by over 10x. Microstructural analysis confirms GO@EGaIn composite stability and enhanced electrochemical performance. Utilizing this, a thin‐film supercapacitor is fabricated. Results indicate that when coating the EGaIn with GO to EGaIn ratio of 0.001, the areal capacitance improves by 10 times, reaching 20.02 mF cm−2. This breakthrough paves the way for advanced liquid metal‐based thin‐film electrodes, promising significant improvements in energy storage applications.
Continuous Growth of Crystalline InGaZnO on InLaO by Spray Pyrolysis for High‐Performance Thin‐Film Transistors with Excellent Stability

Published: February 2024

AbstractInGaZnO (IGZO) based thin film transistors (TFTs) are successfully employed in commercial displays due to their excellent electrical properties but next‐generation displaybackplanes demand higher mobility. A heterojunction structure crystalline oxides can offer superior mobility and stability. Herein, the continuous growth of IGZO is reported on the crystalline InLaO (ILO) layer by spray pyrolysis, which closely resembles the crystalline structure of grown ILO layer. The crystalline structure of the IGZO is confirmed by grazing incidence X‐ray diffraction and high‐resolution transmission electron microscopy. The bilayer IGZO/ILO TFT exhibits remarkable electrical performance, including a high saturation mobility of 55.0 cm2 V−1 s−1, low subthreshold swing of 110 mV dec−1, and high ION/OFF ratio of ≈109 with excellent stability under positive bias temperature stress with In addition, the inverter and ring oscillator based on the IGZO/ILO TFTs demonstrate a high voltage gain of 120 and a low propagation delay of 16.8 ns, respectively. The remarkable performance of bilayer IGZO/ILO TFT by spray pyrolysis is attributed to the In2O3‐like crystalline IGZO grown on ILO film. This leads to reduced lattice mismatch, resulting in minimizing grain boundaries and defects that can hinder electron transport at the interface. The matched crystal structure leads to efficient charge transport at the IGZO and ILO heterojunction, resulting in remarkable TFT performance.

AbstractWindows are used everywhere, from buildings to vehicles. Smart switchable windows are highly sought‐after in order to reduce energy consumption. An ideal smart window should have two functions. First, it should be able to control privacy. Second, it should be able to control radiant energy flow. Here, a smart window is reported that possesses the two functions. The smart window is based on a dichroic dye‐doped cholesteric liquid crystal. It exhibits two stable states in the absence of applied voltage. One of them is the planar state that is optically absorbing without haze and can control radiant energy flow. The other state is the focal conic state that is optically scattering and can control privacy. Furthermore, when voltage is applied, the liquid crystal is switched to a heliconical state, where the transmittance can be tuned continuously. Thanks to its superior performance, this smart window has a big potential for applications in architectural and vehicle windows.

AbstractMetal halide perovskites (MHPs) exhibit electronic and ionic characteristics suitable for memristors. However, polycrystalline thin film perovskite memristors often suffer from reliability issues due to grain boundaries, while bulk single‐crystal perovskite memristors struggle to achieve high LRS/HRS ratios. In this study, a single crystal memristive device utilizing a wide bandgap perovskite is introduced, MAPbBr3, in a high surface/thickness configuration. This thin single crystal overcomes these challenges, exhibiting a remarkable LRS/HRS ratio of up to 50 and endurance of 103 cycles, representing one of the highest reported values to date. This exceptional stability enables to analyze the electroforming process and LRS through impedance spectroscopy, providing insights into the underlying operational mechanism. As far as it is known, this is the first reported thin single‐crystal MHP memristor device and the first time that the electroforming process is recorded through impedance spectroscopy. This device's outstanding stability and performance position it as a promising candidate for high‐density data storage and neuromorphic applications.

Published: February 2024

AbstractObjectivesClinical productivity is an important operational and educational metric for emergency medicine (EM) residents. It is unclear whether working consecutive days and circadian disruption impact resident productivity. The objective of this study was to determine whether there is a correlation between consecutive shifts and productivity.MethodsThis was a single‐site retrospective observational study using data from academic year 2021–2022 (July 1, 2021–June 23, 2022). Productivity was defined as primary resident encounters with patients per hour (PPH). Postgraduate year (PGY)‐1 and PGY‐2 productivity data and schedules were abstracted from the electronic medical record and scheduling software. Descriptive statistics, including arithmetic mean, standard deviation, and confidence interval (CI), were determined for each shift number and stratified by PGY level. Subgroup analysis of night shifts was performed. Analysis of variance and linear regression analysis were performed.ResultsA total of 2950 shifts were identified, including 1328 PGY‐1 shifts and 1622 PGY‐2 shifts, which involved a total of 32,379 patient encounters. PGY‐1 residents saw a mean of 0.88–0.96 PPH on sequential shifts 1–7, respectively (y‐intercept 0.923, slope 0.001, 95% CI −0.008 to 0.009, p = 0.86). PGY‐2 residents saw a mean of 1.61–1.75 PPH on Shifts 1–7, respectively (y‐intercept 1.628, slope 0.004, 95% CI –0.007 to 0.015, p = 0.50). A subgroup analysis of 598 overnight shifts (11 p.m.–7 a.m.) was performed, in which residents saw a mean of 1.29–1.56 PPH on Sequential Shifts 1–7 (y‐intercept 1.286, slope 0.011, 95% CI −0.011 to 0.033, p = 0.34).ConclusionsEM resident productivity remained relatively constant across consecutive shifts, including night shifts. These findings may have educational and operational implications. Further research is required to understand patient‐ and provider‐oriented consequences of consecutive shift scheduling.
Role of social network in fostering consumers' omni‐channel purchasing behavior towards infant milk powder retailers

Published: February 2024

AbstractSocial network plays an essential role in the consumers' omni‐channel purchasing behaviors (OPBs). In this context, this research delves into two questions. First, do consumers make the omni‐channel purchase decision of infant milk powder via social network? Second, which social network do consumers prefer about the different buying channel? To solve these problems, employing the Berry–Levinson–Pakes and distance‐metric models, we explore the impact of social network modes on the consumers' OPBs based on the home‐scan consumption data. These analyses provide compelling evidence for the positive impact of social network on consumers' OPBs. In particular, recommendation from friends accounts for 90.57% of the contribution to the increase in the online consumers' utility, whereas the voice from relative explains about 50% of the contribution to the offline consumers' utility, which is positively associated with consumer income. The regression results also demonstrate that (i) consumer trust has a significant moderating role in the consumers' OPBs and (ii) consumer trust has a larger moderating role in the consumers' OPBs relative to single‐channel purchasing behavior. We expect that this paper can contribute to the existing literature and provide marketers with important practical suggestions [EconLit Citations: Q11, Q13].
The Photosalient Effect and Thermochromic Luminescence Based on o‐Carborane‐Assisted π‐Stacking in the Crystalline State
Authors: Yuhara Kazuhiro , Tanaka Kazuo 
Published: February 2024

AbstractHerein, we report the unique multiple‐stimuli responsiveness of anthracene‐tethered o‐carborane derivatives. We designed and synthesized anthracene derivatives with different substitution positions and numbers of the o‐carborane units. Two compounds had characteristic crystal structures involving the columnar π‐stacking structures of the anthracene units. From the analysis of crystalline‐state structure–property relationships, it was revealed that the crystals exhibited the photosalient effect accompanied by photochemical [4+4] cycloaddition reactions and temperature‐dependent photophysical dual‐emission properties including excimer emission of anthracene. Those properties were considered as non‐radiative and radiative deactivation pathways through the excimer formation in the excited state and the formation of excimer species was facilitated by the π‐stacking structure of anthracene units. Moreover, we found unusual temperature dependency on the occurrence of the photosalient effect. According to the data from variable temperature X‐ray crystallography, a strong correlation between lattice shrinkage and strain accumulation is suggested.

AbstractThe evolving dynamics of climate change and water resource management present unique challenges for the research and conservation of archaeological heritage, particularly within reservoirs. The Dolmen of Guadalperal in Spain and its surrounding archaeological sites exemplify such a scenario. This study is dedicated to the development and application of a comprehensive methodology for archaeological documentation and site detection, integrating an array of approaches including Synthetic Aperture Radar (SAR) from Sentinel‐1, photogrammetric restitution using historical imagery and geometric recording of sites with diverse sensing equipment. A distinctive aspect of this research lies in juxtaposing multibeam sonar data, typically associated with underwater surveys, with standard land‐based documentation methods like photogrammetry and LiDAR. The results demonstrate the effectiveness of integrating data from these diverse techniques in detecting new archaeological sites and monitoring their alterations, which could be potentially harmful.
Exploring experiences of online ‘pro‐ana’ networks: An interpretative phenomenological analysis approach
Authors: Sharman Jessica , Rolfe Alison , Morrey Tara 
Published: February 2024

AbstractObjectiveOnline pro‐ana communities encourage, rather than denounce, eating disorder (ED) behaviours. Most research analyses online pro‐ana content. Fewer studies have interviewed bloggers directly. To the authors' knowledge, no previous studies have analysed both posts and interview data from pro‐ana bloggers. This study aimed to explore bloggers' experiences of online pro‐ana communities, analysing posts and interview data.MethodFive pro‐ana bloggers participated in semi‐structured interviews over Skype or Telegram. Bloggers' posts and interview data were analysed using interpretative phenomenological analysis, a qualitative method of analysis that emphasises the detailed exploration of participants' individual experiences and how they make sense of these experiences.ResultsFive superordinate themes were identified: ambivalence towards pro‐ana; social support; ‘Ana’ way of life; body/weight desperation; and hidden ED identity. Participants reported hiding their pro‐ana blog, for fear of judgement from offline others. In contrast, participants experienced online pro‐ana communities as a source of understanding, connection and solidarity that counteracted stigma experienced in the offline world. All participants idealised ‘Ana’ (anorexia), either as an admirable lifestyle or as the idealised, personification of anorexia, named ‘Ana’. Simultaneously, participants experienced pro‐ana communities as deceptive and/or harmful, demonstrating ambivalence towards pro‐ana.ConclusionsFindings suggest that community and shared understanding are important to individuals accessing pro‐ana content. Therapists may explore this further with clients, alongside any ambivalence towards pro‐ana and/or alternative supportive environments, such as online support groups. This may reduce isolation, without idealising ED behaviours. Future research could explore bloggers' relationships with the personified ‘Ana’ and experiences of non‐Western and male users.

AbstractAn organocatalytic [3+2] cycloaddition reaction between thiazolidine‐containing β‐ketoester 1 and aryl azides 2 was employed to synthesize new 1,2,3‐triazolyl‐thiazolidine hybrids 3. In this metal‐free approach, twelve compounds were isolated in yields ranging from 23 % to 96 % by using diethylamine (10 mol%) and DMSO at 75 °C for 24 hours. DNA‐binding assays were conducted through absorption, emission spectroscopy and viscosimetry analysis, to evaluate the interaction capacity of the studied derivatives with nucleic acids. All the synthesized compounds were evaluated for their interactions with a specific group of compounds containing the pharmacophoric groups triazole and thiazolidine through a molecular docking speculative study, aimed at identifying the interaction profile of these compounds with DNA. The obtained results suggest that 1,2,3‐triazolyl‐thiazolidine hybrids could be a promising approach in the development of novel therapeutic agents targeting DNA‐related processes.

Apraxia of speech due to the left postcentral gyrus lesion
Authors: Mitani Naoko , Sakurai Yasuhisa 
Published: February 2024

Key Clinical MessageApraxia of speech (AOS) due to a postcentral infarction differs from conventional precentral AOS with respect to phonemic errors (phoneme substitution) which are more common than phonetic errors (phoneme distortion) and preserved accent and intonation.AbstractClinical features of apraxia of speech caused by lesions in the postcentral gyrus have not yet been elucidated. Here, we report a patient with this lesion and show how postcentral apraxia of speech differs from the hitherto known precentral apraxia of speech. A 54‐year‐old man developed Broca's aphasia with apraxia of speech that resolved into pure apraxia of speech within 3 weeks following infarction of the postcentral gyrus. The diagnosis of apraxia of speech was based on the patient's effortful, slow speech and inconsistent phonetic distortions with phonemic paraphasia. The Western Aphasia Battery was used to examine the patient's speech samples. Speech was recorded using a digital voice recorder and transcribed into a narrow transcription of the International Phonetic Alphabet. The error types were categorized phonologically. The results revealed that (a) phonemic errors (vowel and consonant substitutions, also known as phonemic paraphasia) were more common than phonetic errors (vowel and consonant distortions). Similar to conduction aphasia, phonemic errors were more pronounced in confrontation naming than in repetition, accompanied by self‐correction, and (b) word accent and sentence intonation were preserved, although the speech was slow. These two features are characteristic of postcentral apraxia of speech, which can be differentiated from conventional precentral apraxia of speech.

Key Clinical MessageThis case highlights the importance of early diagnosis and treatment in prognosis of fulminant multiple sclerosis, and its similar management with autoimmune encephalitis in some clinical settings, in which these diseases are indistinguishable. This case also supports the use of rituximab in these patients with an adequate response to plasmapheresis.AbstractEarly diagnosis and treatment of fulminant multiple sclerosis (MS), also known as Marburg' or malignant variant of MS (MVMS), is of great value in reducing morbidity and mortality. Seronegative autoimmune encephalitis (AIE) is very similar to, and sometimes indistinguishable from, fulminant MS. However, the acute and long‐term management of the two diseases is often the same. This article describes the clinical course of a patient suspected of having MVMS or AIE and the challenges of their differential diagnosis and management.
