Published: March 2024

AbstractThe development of efficient, bright, and stable narrowband light‐emitting electrochemical cells (LECs) has remained a challenge. Here, intrinsically ionic multi‐resonance thermally activated delayed fluorescence (MR‐TADF) emitters are reported as guest emitters for narrowband LECs, which are developed by attaching an imidazolium cation onto a typical MR‐TADF emitter. In solution, the emitters show green–blue emission peaked at 486−497 nm with small full widths at half‐maximum (FWHMs) at 24−26 nm. In doped films, they show narrowband green–blue emission with high luminescent efficiencies at ≈90%. LECs using an ionic exciplex host and the ionic MR‐TADF guest emitters show green–blue emission peaked at 494−503 nm with small FWHMs at 31−34 nm, and afford high external quantum efficiencies (EQEs) up to 10% under constant‐voltage driving. With ionic TADF small‐molecule hosts, the narrowband LECs show high EQEs up to 13.0% under constant‐voltage driving, which is the highest among all reported narrowband LECs, and afford peak brightness/EQE/half lifetime at 780 cd m−2/5.6%/62.2 h under constant‐current driving. A long half‐lifetime of ≈630 h has further been achieved at 136 cd m−2. The work demonstrates the great potential for the use of intrinsically ionic MR‐TADF guest emitters and ionic TADF hosts to develop efficient, bright, and stable narrowband LECs.

AbstractPremiseVertical stratification is a key feature of tropical forests and plant–frugivore interactions. However, it is unclear whether equally strong patterns of vertical stratification exist for plant–nectarivore interactions and, if so, which factors drive these patterns. Further, nectar‐inhabiting bacteria, acting as “hidden players” in plant–nectarivore interactions, might be vertically stratified, either in response to differences among strata in microenvironmental conditions or to the nectarivore community serving as vectors.MethodsWe observed visitations by a diverse nectarivore community to the liana Marcgravia longifolia in a Peruvian rainforest and characterized diversity and community composition of nectar‐inhabiting bacteria. Unlike most other plants, M. longifolia produces inflorescences across forest strata, enabling us to study effects of vertical stratification on plant–nectarivore interactions without confounding effects of plant species and stratum.ResultsA significantly higher number of visits were by nectarivorous bats and hummingbirds in the midstory than in the understory and canopy, and the visits were strongly correlated to flower availability and nectar quantity and quality. Trochiline hummingbirds foraged across all strata, whereas hermits remained in the lower strata. The Shannon diversity index for nectar‐inhabiting bacterial communities was highest in the midstory.ConclusionsOur findings suggest that vertical niche differentiation in plant–nectarivore interactions seems to be partly driven by resource abundance, but other factors such as species‐specific preferences of hummingbirds, likely caused by competition, play an important role. We conclude that vertical stratification is an important driver of a species’ interaction niche highlighting its role for promoting biodiversity and ecosystem functioning.
On (not) being literate enough: The literacy experiences and literacy programme needs of people experiencing homelessness or who are at risk of homelessness
Authors: Hanckel Benjamin , Morris Alan , Yasukawa Keiko 
Published: March 2024

AbstractThis paper is focussed on literacy and the literacy experiences of people who are experiencing homelessness or are at risk of homelessness. Drawing on 23 in‐depth interviews with people who have lived experience of homelessness in Sydney, Australia, the paper examines literacy, literacy needs and interest in literacy programmes from a social practice perspective of literacy. Amartya Sen's (1999) capability approach is drawn on to examine the multidimensional barriers that impede access to literacy. Our findings show literacy needs and how literacy is understood and valued in the lives of people with lived experience of homelessness. We show the ways that spatial and temporal conditions enable and create (im)possibilities for the realisation of literacy as a capability. We also discuss how the capability is imagined to fit into existing worlds, as both an instrumental tool, as well as for personal satisfaction and broader participation in social life. Our interviewees also point to the possibilities of literacy learning and programmes supporting the realisation of other capabilities, emphasising the prospects of achieving multiple capability realisations through program design. We show how the findings bear out the principles of a social practices pedagogy in adult literacy programmes.
Implementation of a Blended‐Learning Perioperative Nursing Education Program in Canada
Authors: Li Jack S. , Conway Aaron 
Published: March 2024

ABSTRACTGovernmental COVID‐19 mandates in Ontario, Canada, resulted in a backlog of perioperative procedures. Organization leaders were required to expand services after the pandemic; however, the ongoing nursing shortage and college‐based structure of perioperative education programs complicated their response. In 2021, we developed an in‐house perioperative education program using a blended‐learning theory comprising online modules and videos, skills laboratory sessions, and clinical placement experiences. Nurses were required to apply for the program and remain employed at the facility for two years. Program evaluations showed that the novice nurses felt confident when beginning clinical experiences and preceptors believed the nurses were prepared for practice. Sixteen of 19 participants successfully completed the program, which helped resolve the staffing shortage. Novice nurses may benefit from a shadowing experience before applying for this type of program. Leaders in nonperioperative specialties should consider an in‐house education program to help meet staffing needs in their areas.

Published: March 2024

AbstractThis study evaluated the self‐healing characteristics of superabsorbent polymers (SAP) in epoxy polyamide paint systems applied using brush application. The SAP underwent preliminary characterization to determine its primary properties and was then incorporated into the epoxy primer at different percentages. The epoxy‐SAP coating systems then underwent various tests to evaluate their self‐healing capability. Excellent adhesion is obtained with the coating system composed of initial epoxy primer, epoxy‐SAP layer, final epoxy primer, and an epoxy enamel topcoat. Electrochemical impedance spectroscopy (EIS) reveals that the addition of SAP increased the charge transfer resistance and pore resistance and decreased the double layer capacitance of the coating system in a span of 5 h, confirming the self‐healing of the coating. Maximum corrosion protection for 5 h is obtained between 15 to 20 wt% SAP. Lastly, it is determined through long‐term immersion tests that the addition of SAP in the coating significantly decreases the rust formation; however, the coating starts to peel off due to the swelling of SAP after 2–3 days.
Increased atmospheric PM2.5 events due to open waste burning in Qaanaaq, Greenland, summer of 2022

Published: March 2024

AbstractHigh levels of particulate matter (PM) are relevant to severe air pollution and can adversely impact human health. Maintaining healthy air quality for the residents of the Arctic region is essential to satisfy the no‐one‐left‐behind policy of the Sustainable Development Goals (SDGs) by the United Nations. In this study, we installed a PM2.5 measurement system in Qaanaaq, Greenland, and obtained the first continuous PM2.5 measurements from July 20, 2022 to August 13, 2022. We observed several increased PM2.5 events; relatively high PM2.5 levels persisted from August 8, 2022. On the same day, visible black smoke emitted from the Qaanaaq dump site originated from open waste burning. By confirming less transboundary air pollution contributions from remote aerosol source regions to Qaanaaq during the measurement period using NOAA's HYSPLIT backward trajectory analysis and NASA's MERRA‐2 aerosol re‐analysis, we confirmed that the increased PM2.5 was primarily due to local open waste burning with less contributions from transboundary air pollution. However, small contributions from biomass burning outside Greenland were plausible during the early measurement period. Additionally, NOAA's HYSPLIT dispersion calculations suggested possible aerosol depositions from local open waste burning to nearby sea areas, such as Baffin Bay. Although the hourly mean PM2.5 mass concentration was not alarmingly high during the measurement period, future studies should incorporate longer‐term continuous PM2.5 measurements along with other atmospheric chemical analyses to identify possible local air pollution sources in detail to ensure clean ambient air for the future in the Arctic. Our study provides quantitative evidence of the impact of open waste burning on air quality at a study site in Greenland, which could be crucial in developing air quality policies for this region in the Arctic.
The Aptly Buried “I” in Experience: Experiential Purchases Promote More Social Connection Than Material Purchases
Authors: Kumar Amit , Mann Thomas C. , Gilovich Thomas 
Published: March 2024

ABSTRACTExperiential purchases (focused on doing rather than having) provide more satisfaction than material goods. Here, we examine a different downstream consequence of spending money on experiences: fostering social connection. Consumers reported feeling more kinship with someone who had made a similar experiential purchase than someone who had made a similar material purchase—a result tied to the greater centrality of experiences to one's identity. This greater sense of connection that experiences provide applied even when someone else had made a similar, but superior purchase. Participants also reported feeling more connected to others in general, not just those who have made the same purchase, when reflecting on experiential consumption—and these feelings of connection were expressed in a greater desire to engage in social activities when participants considered their experiential purchases than when they considered their material purchases. Together, these results demonstrate that experiential consumption enhances people's social connection quite broadly.

Successful treatment of body integrity dysphoria with amputation: A case report
Authors: Nadeau Nadia 
Published: March 2024

Key Clinical MessageIn select cases of body integrity identity disorder or body integrity dysphoria where noninvasive treatments prove ineffective and the patient's distress is substantial, elective amputation may serve as a viable and highly satisfying intervention, aligning the individual's physical self with their perceived identity.AbstractThis case report presents an illustration of body integrity identity disorder (BIID), wherein a 20 years old ambidextrous male experiencing profound distress over his left hand's fourth and fifth fingers sought elective amputation after noninvasive treatments proved unsuccessful. Despite ethical concerns and limited literature on BIID, the decision to proceed with elective surgery was based on the patient's sustained desire, potential risks of self‐harm, and the distinct presentation involving two fingers rather than a complete limb. Following amputation, the patient experienced immediate relief, with nightmares ceasing, emotional distress subsiding, and improved functionality. This case highlights the potential efficacy and patient satisfaction associated with elective amputation in specific BIID presentations, shedding light on the unique challenges faced by affected individuals and emphasizing the importance of understanding, support, and inclusive healthcare practices.

Published: March 2024

Key Clinical MessageA case of major aphthous‐like ulcer was described in a 50‐year‐old patient. The patient showed the main signs of aphthous stomatitis painful ulcer, 1–2 cm in diameter, located on the ventral of the tongue, buccal mucosa, and the palate. These ulcers persisted for more than 3 weeks. The patient's self‐administration of a nonsteroidal anti‐inflammatory drug (NSAID) was suggested as the leading cause of aphthous‐like ulcers in this case. ulcers were treated with dexamethasone mouthwash and low‐level laser therapy (LLLT).
Metal Phthalocyanine Sensitized Photoelectrochemical Cell Assembling with Azide‐Functionalized Reduced Graphene and Quaternary Metal Chalcogenide Composites

Published: March 2024

AbstractHere, photoelectrodes of photoelectrochemical (PEC) cells consisting of azide functionalized reduced graphene oxide (GO‐N3) and quaternary metal chalcogenide (CdZnNiSSe) composites sensitized with metal phthalocyanines (MPc, M: Co, Zn, Ti) are developed and then tested in hydrogen evolution reaction (HER). CdZnNiSSe/RGO‐N3 composite is deposited on an indium tin oxide (ITO) electrode through a facile electrodeposition technique and ITO/CdZnNiSSe/RGO‐N3 photoelectrode is constructed. Then, MPcs bearing terminal alkyne groups are connected to RGO‐N3 via the copper(I)‐catalyzed azide‐alkyne cycloaddition (click chemistry) technique to produce ITO/CdZnNiSSe/RGO‐N3‐MPc structures. Decoration of ITO/CdZnNiSSe/RGO‐N3 with MPcs is proposed to improve the charge transfer capability of the photoelectrode due to wide light absorption of MPcs from UV toward the IR region of the light spectrum. PECHER responses indicate that among the photoanodes bearing ZnPc, CoPc, and TiOPc, ITO/CdZnNiSSe/RGO‐N3‐ZnPc electrode exhibits the highest PECHER performance owing to the suitability of band structure of ZnPc. Sensitizing ITO/CdZnNiSSe/RGO‐N3 with ZnPc increases the photocurrent density from 5.0 to 7.3 mA cm−2 at 0.8 V vs. RHE and the applied bias photon to current efficiency (ABPE) enhances from 3.18 % to 3.87 %. This study provides a new approach for increasing the performance of photoanodes via sensitization with MPcs in photoelectrochemical hydrogen evolution processes for future applications.
INVESTIGATION OF FLEXURAL BEHAVIOUR OF STAINLESS STEEL CHANNEL SECTIONS

Published: March 2024

AbstractIn this paper, the design of austenitic stainless steel channel sections subjected to minor axis bending, specifically with tension in the web (“u” orientation) is analyzed. The values of moment resistance are predicted using Eurocode 3 criteria and the Continuous Strength Method (CSM), which are then compared with numerical models to assess effectiveness. The modeling is performed through ANSYS and calibrated with literature tests. It was found that Eurocode presents a considerable disparity in results, as well as an overly cautious response (on average, half the numerical load). The CSM reflects the performance more accurately but still with a certain level of conservatism (on average, around 35% lower).
New Phenanthro[9,10‐d]oxazole‐Based Fluorophores with Hybridized Local and Charge‐Transfer Characteristics for Highly Efficient Blue Non‐Doped OLEDs with Negligible Efficiency Roll‐Off

Published: March 2024

AbstractIt is vital to develop highly efficient non‐doped blue organic light‐emitting diodes (OLEDs) with high color purity and low‐efficiency roll‐off for applications in display and lighting. Herein, two blue D‐A fluorophores TPA‐PO and TPA‐DPO are designed and synthesized, in which phenanthro[9,10‐d]oxazole (PO) acts as the acceptor and triphenylamine as the donor. TPA‐PO and TPA‐DPO display good thermal stability and efficient luminescence efficiency in neat film. Results based on photophysical property and theoretical calculation demonstrate that TPA‐PO and TPA‐DPO possess the hybridized local and charge‐transfer (HLCT) feature, which can utilize the triplet exciton to achieve highly efficient electroluminance (EL). The non‐doped OLEDs with TPA‐PO/TPA‐DPO as pure emissive layer show the uniform EL emission peak at 468 nm, corresponding to CIE coordinates of (0.168, 0.187) and (0.167, 0.167), respectively. The TPA‐DPO‐based non‐doped OLEDs provide the maximum external quantum efficiency (EQE) of 7.99 % and high exciton utility efficiency of 48.4 %~72.6 %. Moreover, the TPA‐DPO‐based device exhibits low‐efficiency roll‐off, still maintaining the EQE of 6.03 % at the high luminance of 5000 cd m−2. Those findings state clearly that PO is a promising building block of blue fluorophore with a potential HLCT feature to be applied in non‐doped OLEDs.
Robust Red‐Absorbing Donor‐Acceptor Stenhouse Adduct Photoswitches

Published: March 2024

AbstractDonor‐Acceptor Stenhouse Adduct (DASA), a class of push‐pull negative photochrome, has received large interest lately owing to its versatile synthesis, modularity and excellent photoswitching in solutions. From a technological perspective, it is imperative for this class of photoswitches to work robustly in solid state, e. g. thin films. We feature a molecular framework for the optimized design of DASAs by introducing a new thioindoline donor (D3) and assessing its performance against known 2nd generation indoline‐based donors. The systematic structure‐function investigations suggest that to achieve robust reversible photoswitching, a ground state with low charge separation is desired. DASAs with stronger electron donors and a larger charge separation in the ground state result in a low population of the photothermalstationary state (PTSS) and reduced photostability. The DASA with thioindoline donor (D3A3) seems to be a special case among the donor series as it causes a red shift (ca. 15 nm), however with less polarization of the ground state and marginally better photostability as compared to the unsubstituted 2‐methyl indoline (D1A3). We also emphasize the consideration of the key additional factors that can modulate the red‐light photoswitching properties of DASA chromophores in polymer thin films, which might not be dominant in homogenous solution state.

AbstractBlue LEDs‐irradiation of a mixture of N,N,N',N'‐tetramethylethylenediamine (TMEDA) and perfluoroalkyl iodides (RF−I) – Electron Donor Acceptor (EDA)‐complex – in the presence of triphenylamines (TPAs) in an aqueous solvent mixture afforded mono‐perfluoroalkylated triphenylamines (RF−TPA) in good yields. These RF−TPA were further subjected to acetone‐sensitized [6π]‐electrocyclization at 315 nm‐irradiation affording exclusively perfluoroalkylated endo‐carbazole derivatives (RF−CBz) in quantitative yields. Mechanistic studies and photophysical properties of products are studied.

Published: March 2024

AbstractGlucose holds significant importance in disease diagnosis as well as beverage quality monitoring. The high‐efficiency electrochemical sensor plays a crucial role in the electrochemical conversion technology. Ni(OH)2 nanosheets are provided with high specific surface area and redox activity that are widely used in electrochemistry. Conductive metal‐organic frameworks (cMOFs) perfectly combine the structural controllability of organic materials with the long‐range ordering of inorganic materials that possess the characteristic of high electron mobility. Based on the above considerations, the combination of Ni(OH)2 and Ni‐HHTP (HHTP=2,3,6,7,10,11‐hexahydroxytriphenylene) as an electrode modification material is designed to enhance electrochemical performance. In this work, to improve glucose detection, a sequence of Ni(OH)2@NiCo‐HHTP and NiM‐LDH@Ni‐HHTP (M=Co2+, Mn2+, Cu2+, LDH=layered double hydroxide) are successfully synthesised by doping metals into Ni‐HHTP and Ni(OH)2, respectively. As a result, NiCu‐LDH@Ni‐HHTP showed the best excellent glucose detection sensitivity.
