AbstractThe establishment of abundant three‐phase interfaces with accelerated mass transfer in air cathodes is highly desirable for the development of high‐rate and long‐cycling rechargeable zinc–air batteries (ZABs). Covalent organic frameworks (COFs) exhibit tailored nanopore structures, facilitating the rational tuning of their specific properties. Here, by finely tuning the fluorinated nanopores of a COF, a novel air cathode for rechargeable ZABs is unprecedentedly designed and synthesized. COF nanosheets are decorated with fluorinated alkyl chains, which shows high affinity to oxygen (O2), in its nanopores (fluorinated COF). The fluorinated COF nanosheets are stacked into well‐defined O2‐transport channels, which are then assembled into aerophilic “nano‐islands” on the hydrophilic FeNi layered‐double‐hydroxide (FeNi LDH) electrocatalyst surface. Therefore, the mass‐transport “highway” for O2 and water is segregated on the nanoscale, which significantly enlarges the area of three‐phase boundaries and greatly promotes the mass‐transfer therein. ZABs based on the COF‐modified air cathode deliver a small charge/discharge voltage gap (0.64 V at 5 mA cm−2), a peak power density (118 mW cm−2), and a stable cyclability. This work provides a feasible approach for the design of the air cathodes for high‐performance ZABs, and will expand the new application of COFs.

Published: February 2023

AbstractSynthetic photonic materials exploiting the quantum concept of parity–time (PT) symmetry lead to an emerging photonic paradigm—non‐Hermitian photonics, which is revolutionizing the photonic sciences. The non‐Hermitian photonics dealing with the interplay between gain and loss in PT synthetic photonic material systems offers a versatile platform for advancing microlaser technology. However, current PT‐symmetric microcavity laser systems only manipulate imaginary parts of the refractive indices, suffering from limited laser spectral bandwidth. Here, an organic composite material system is proposed to synthesize reconfigurable PT‐symmetric microcavities with controllable complex refractive indices for realizing tunable single‐mode laser outputs. A grayscale electron‐beam direct‐writing technique is elaborately designed to process laser dye‐doped polymer films in one single step into microdisk cavities with periodic gain and loss distribution, which enables thresholdless PT‐symmetry breaking and single‐mode laser operation. Furthermore, organic photoisomerizable compounds are introduced to reconfigure the PT‐symmetric systems in real‐time by tailoring the real refractive index of the polymer microresonators, allowing for a dynamically and continuously tunable single‐mode laser output. This work fundamentally enhances the PT‐symmetric photonic systems for innovative design of synthetic photonic materials and architectures.

Published: February 2023

AbstractCircular supply chains require more accurate product labeling and traceability. In the apparel industry, product life cycle management is hampered in part by inaccurate, poorly readable, and detachable standard care labels. Instead, this article seeks to enable a labeling system capable of being integrated into the fabric itself, intrinsically recyclable, low‐cost, encodes information, and allows rapid readout after years of normal use. In this work, all‐polymer photonic crystals are designed and then fabricated by thermal drawing with >100 layers having sub‐micrometer individual thickness and low refractive index contrast (Δn = 0.1). The fibers exhibit reflectance features in the 1–5.5 µm wavelength range, characterized using insitu Fourier transform infrared spectroscopy. Drawn photonic fibers are then woven into fabrics, characterized by near‐infrared spectroscopy and short‐wave infrared imaging, techniques commonly used in industrial facilities for sorting materials. The fibers’ optical design also enables the use of overtone peaks to avoid overlap with parasitic molecular absorption, substantially improving the signal‐to‐noise ratio (and therefore ease and speed) of readout. The ability to produce kilometers of fiber that are compatible with existing textile manufacturing processes, coupled with low input material cost, make these a potential market‐viable improvement over the standard care label.

AbstractWith the ever‐growing presence of silver nanoparticles in consumer products, there is a need for cost‐effective and on‐site monitoring of their influence on our environment. Herein, we report the use of screen‐printed and laser‐ablated microelectrode arrays (SPMEAs) for the electrochemical detection of 20 nm‐sized silver nanoparticles (AgNPs) via collision electrochemistry. The electrodes’ morphology is optically analyzed and their electrochemical properties later characterized using cyclic voltammetry and impedance spectroscopy. The SPMEAs are calibrated using a AgNP concentration range of 1 to 100 pM, resulting in a linear dependency of 22 mHz pM−1 for the impact frequency. Finally, to demonstrate the possibility of future on‐site applications, an in‐house built portable nanoparticle detection (POND) device is used to measure Faradaic AgNP impacts on a SPMEA, in a solution contaminated with urea.

AbstractObjectivesDespite decades of literature recognizing racial disparities (RDs) in emergency medicine (EM), published curricula dedicated to addressing them are sparse. We present details of our novel RD curriculum for EM clerkships and its educational outcomes.MethodsWe created a 30‐min interactive didactic module on the topic designed for third‐ and fourth‐year medical students enrolled in our EM clerkships. Through a modified Delphi process, education faculty and content experts in RD developed a 10‐question multiple‐choice test of knowledge on RD that the students completed immediately prior to and 2 weeks following the activity. Students also completed a Likert‐style learner satisfaction survey. Median pre‐ and posttest scores were compared using a paired Wilcoxon signed‐rank test and presented using medians and 95% confidence intervals (CIs). Satisfaction survey responses were dichotomized into favorable and neutral/not favorable.ResultsFor the 36 students who completed the module, the median pretest score was 40% (95% CI 36%–50%) and the posttest score was 70% (95% CI 60%–70%) with a p‐value of <0.001. Thirty‐five of the 36 students improved on the posttest with a mean increase of 24.2% (95% CI 20.2–28.2). The satisfaction survey also showed a positive response, with at least 83% of participants responding favorably to all statements (overall mean favorable response 93%, 95% CI 90%–96%).ConclusionsThis EM‐based module on RD led to improvement in students' knowledge on the topic and positive reception by participants. This is a feasible option for educating students in EM on the topic of RD.

AbstractObjectivesThe increased availability of genome‐wide data allows capturing the fine genetic structure of present days populations. Here we analyze the genetic ancestry at a fine scale of an Argentinean Patagonia population to understand the origins beyond the three‐hybrid model, and to compare these results with volunteers' self‐perceived ancestry in a broad context encompassed by historical and familiar information.Materials and MethodsWe compare high‐throughput genotyping data for 92 individuals that we generated to data sets from the literature by applying fully haplotype‐based methods to examine patterns of human population substructure. The volunteers filled out a semi‐structured questionnaire, including questions about their history, ancestors, and self‐perceived ancestry. Finally, we used non‐parametric tests in order to compare genomic ancestry against self‐perception.ResultsGenetic ancestry from Iberian populations accounted for 0.176 (Spain and Basque origins), while the component associated with Italian populations accounted for 0.140. We observed a 0.169 Native American genetic ancestry. Participants significantly over‐ and under‐ self‐perceived Native American and European origins, respectively. Components of origins from North Africa to Central South Asia accounted for 0.225 of the genetic ancestry in the sample, with significantly higher proportions for people that mentioned such origins in their genealogical history.DiscussionWe captured the fine‐genetic architecture of a Puerto Madryn population sample in Chubut province, showing that self‐perceived ancestry remains a poor proxy for genetic ancestry. The presence of North Africa to Central South Asia components and its correlate with self‐perception of these origins justifies its inclusion in future miscegenation studies in Argentina.
Lessons from lockdown: Autistic students, parents and mainstream schools

Published: February 2023

AbstractThis paper reports on the findings of a BERA‐funded small‐scale project that explores the impacts of COVID‐19 lockdowns on the educational experiences of autistic children and young people who attend mainstream schools and their parents/carers in England. We observe that, unsurprisingly, lockdown resulted in associated stresses for families. However, our main argument is that for the participants, the pandemic has not been experienced to the same extent as is popularly understood; that is, causing major disruption to children's schooling experiences and/or unusual levels of social isolation. Using the concept of stigma as a theoretical resource, we argue that this is because the families with whom we spoke were already experiencing, pre‐COVID‐19, disrupted schooling and degrees of social isolation. Indeed, for many of the young people, the break from school occasioned by lockdown allowed them a release from the more negative and stigmatising aspects of their routine experiences within school. We therefore argue that the disruption of the pandemic sheds light on how stigma shapes students' daily school experiences.

AbstractHere, we study the dielectric and optical properties of two‐dimensional (2D) WX2 monolayers, where X is Cl, O, S, Se, and Te. First principle electronic band structure calculations reveal that all materials are direct band gap semiconductors except WO2 and WCl2, which are found to be indirect band gap semiconducting 2D materials. The dielectric response of these materials is also systematically investigated. The obtained results suggest that these materials are suitable as dielectric materials to suppress unwanted signal noise. The optical properties of these 2D materials, such as absorption, reflection and extinction coefficients, refractive index, and optical conductivity, are also calculated from the dielectric function. It is found that these materials exhibit excellent optical response. The present electronic, dielectric, and optical findings indicate that WX2 monolayers have an opportunity in electronic, optical, and optoelectronic device applications.
Multiplexing near‐infrared quantum dot fluorescence through vibrational and electronic transition signatures

Published: February 2023

AbstractWe represent how the multiplexing power of near‐infrared (NIR) quantum dot (QD) signals can be extended by using narrow NIR absorptive features such as molecular vibration modes and lanthanide f‐f electronic transitions. Two distinguishable NIR absorptive films were prepared by using polystyrene and samarium complex, and combined with NIR emitting PbS/CdS Core/Shell QD film to make various NIR emitting codes. Spectral features of NIR emitting codes could be diversified by adjusting the thickness and chemical composition of optical films.

Published: February 2023

AbstractConverting CO2 into chemicals, e.g., methanol and dimethyl ether (DME), has been an attractive way to protect the global environment. In this process, the total catalyst volume of the methanol reactor was split into two sections to load the reactors. The catalyst volume of each reactor was optimized by the differential evolution technique. It was concluded that the indirect route yields a higher DME production rate than the direct one, as it produces higher amounts of methanol. CO2 conversions increased by 79 % in the indirect two‐stage process, which resulted in the highest DME production rate of 343 t per day. The results demonstrate how the concept of a two‐stage process in the indirect conversion of CO2 is feasible and beneficial for fuel production.

Metal‐Organic Framework‐Based Colloidal Particle Synthesis, Assembly, and Application
Authors: Song Qing , Shi Shang , Liu Bing 
Published: February 2023

AbstractMetal‐organic frameworks (MOFs) assembled from metal nodes and organic ligands have received significant attention over the past two decades for their fascinating porous properties and broad applications. Colloidal MOFs (CMOFs) not only inherit the intrinsic properties of MOFs, but can also serve as building blocks for self‐assembly to make functional materials. Compared to bulk MOFs, the colloidal size of CMOFs facilitates further manipulation of CMOF particles in a single or collective state in a liquid medium. The resulting crystalline order obtained by self‐assembly in position and orientation can effectively improve performance. In this review, we summarize the latest developments of CMOFs in synthesis strategies, self‐assembly methods, and related applications. Finally, we discuss future challenges and opportunities of CMOFs in synthesis and assembly, by which we hope that CMOFs can be further developed into new areas for a wider range of applications.
Reduced Nucleophilicities ИB of Lewis Bases B: Is ИB Independent of Whether B is Involved in a Hydrogen Bond or a Halogen Bond?
Authors: Alkorta Ibon , Legon Anthony 
Published: February 2023

AbstractReduced nucleophilicities ИB of axially symmetric molecules B were determined from
, where De is the equilibrium dissociation energy of the complexes B⋅⋅⋅XY, NB is the nucleophilicity of B, EXY is the electrophilicity of the halogen‐bond donor XY and
is the minimum electrostatic surface potential of B. The series B⋅⋅⋅ClY, B⋅⋅⋅BrY, B⋅⋅⋅IY (Y=F, Cl, Br, I, CN, and CCH) as well as (B⋅⋅⋅XY, XY=F2, Cl2, Br2,and BrCl) of complexes were investigated. Molecules B were grouped so that the terminal atom involved in the halogen bond was fixed within the group. Groups having N as the terminal atom were RCN (R=CH3, H, and F) or RN (R=N and P), those with C as the terminal atom were RNC (R=H and F) and RC (R=O, S and Se), and those with a terminal O atom were R=C=O (R=O or S). Graphs of
versus EXY for each group were straight lines through the origin, with generally different gradients, hence implying different NB. By contrast, when
was the ordinate the lines conflated to give a single straight line, which then defines a common (reduced) nucleophilicity ИB for that group of B. Hence it was concluded that ИB is an intrinsic property of the terminal atom, independent of the remainder of B, and only weakly dependent on the type (C, N or O) of the terminal atom. Moreover, ИB for each B was the same as determined previously from the hydrogen‐bonded series B⋅⋅⋅HX, (X=F, Cl, Br, I, CN, CCH, and CP).
Murine‐Derived Glioma Organoids and Cell Line Culture Systems

Published: February 2023

AbstractResearch models in cancer have greatly evolved in the last decade, with the advent of several new methods both in vitro and in vivo. While in vivo models remain the gold standard for preclinical studies, these methods present a series of disadvantages such as a high cost and long periods of time to produce results compared with in vitro models. We have previously developed a method named Mosaic Analysis by Dual Recombinase‐mediated cassette exchange (MADR) that generates autochthonous gliomas in immunocompetent mice through the transgenesis of personalized driver mutations, which highly mimic the spatial and temporal tumor development of their human counterparts. Due to the control of single‐copy expression of transgenes, it allows for comparing the visualization of tumor cells and non‐tumor cells. Here we describe a method to generate murine‐derived glioma organoids (MGOs) and cell line cultures from these murine models by physical and enzymatic methods for in vitro downstream applications. Tumor cells can be readily distinguished from non‐tumor cell populations, in both organoids and monolayer cell cultures, and isolated due to the use of personalized fluorescent reporter transgenes. © 2023 Wiley Periodicals LLC.Basic Protocol 1: Generation of 3D murine‐derived glioma organoidsBasic Protocol 2: Generation of 2D glioma monolayer cell lines
