AbstractQuasi‐2D (q2D) conjugated polymers (CPs) are polymers that consist of linear CP chains assembled through non‐covalent interactions to form a layered structure. In this work, the synthesis of a novel crystalline q2D polypyrrole (q2DPPy) film at the air/H2SO4 (95%) interface is reported. The unique interfacial environment facilitates chain extension, prevents disorder, and results in a crystalline, layered assembly of protonated quinoidal chains with a fully extended conformation in its crystalline domains. This unique structure features highly delocalized π‐electron systems within the extended chains, which is responsible for the low effective mass and narrow electronic bandgap. Thus, the temperature‐dependent charge‐transport properties of q2DPPy are investigated using the van der Pauw (vdP) method and terahertz time‐domain spectroscopy (THz‐TDS). The vdP method reveals that the q2DPPy film exhibits a semiconducting behavior with a thermally activated hopping mechanism in long‐range transport between the electrodes. Conversely, THz‐TDS reveals a band‐like transport, indicating intrinsic charge transport up to a record short‐range high THz mobility of ≈107.1 cm2 V−1 s−1.

AbstractThe electrocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) is a promising method for the efficient production of biomass‐derived high‐value‐added chemicals. However, its practical application is limited by: 1) the low activity and selectivity caused by the competitive adsorption of HMF and OH− and 2) the low operational stability caused by the uncontrollable reconstruction of the catalyst. To overcome these limitations, a series of Ni3S2/NiOx‐n catalysts with controllable compositions and well‐defined structures are synthesized using a novel in situ controlled surface reconstruction strategy. The adsorption behavior of HMF and OH− can be continuously adjusted by varying the ratio of NiOx to Ni3S2 on the catalysts surface, as indicated by in situ characterizations, contact angle analysis, and theoretical simulations. Owing to the balanced competitive adsorption of HMF and OH−, the optimized Ni3S2/NiOx‐15 catalyst exhibited remarkable HMF electrocatalytic oxidation performance, with the current density reaching 366 mA cm−2 at 1.5 VRHE and the Faradaic efficiency of the product, 2,5‐furanedicarboxylic acid, reaching 98%. Moreover, Ni3S2/NiOx‐15 exhibits excellent durability, with its activity and structure remaining stable for over 100 h of operation. This study provides a new route for the design and construction of catalysts for value‐added biomass conversion and offers new insights into enhancing catalytic performance by balancing competitive adsorption.

AbstractA readily prepared and functionalized vinylogous nucleophile has been explored and utilized to construct bridged bicyclic compounds. The corresponding cascade Michael/Henry reaction occurred with relatively high reactivity under catalyst‐free and mild conditions. A range of structurally distinct bicyclo[3.2.1]octanes were generated in 40–96% isolated yields with excellent diastereoselectivities (≥10:1 dr). Gram‐scale synthesis was also demonstrated.
Seeking utopia: Psychologies' waves toward decoloniality
Authors: Rodriguez Ramirez Daniel , Langhout Regina D. 
Published: July 2023

AbstractThis paper provides a review of empirical studies published with a decolonial epistemic approach in psychology. Our goal was to better understand how decolonial approaches are being practiced empirically in psychology, with an emphasis on community‐social psychology. We first discuss the context of colonization and coloniality in the research process as orienting information. We identified 17 peer‐reviewed empirical articles with a decolonial approach to psychology scholarship and discerned four waves that characterize the articles: relationally‐based research to transgress fixed hierarchies and unsettle power, research from the heart, sociohistorical intersectional consciousness, and desire‐based future‐oriented research to rehumanize and seek utopia. Community‐social psychology research with a decolonial approach has the potential to remember grassroots efforts, decolonizing our world.

AbstractAlthough considerable efforts towards directly converting syngas to liquid fuels through Fischer–Tropsch synthesis have been made, developing catalysts with low CO2 selectivity for the synthesis of high‐quality gasoline remains a big challenge. Herein, we designed a bifunctional catalyst composed of hydrophobic FeNa@Si‐c and HZSM‐5 zeolite, which exhibited a low CO2 selectivity of 14.3 % at 49.8 % CO conversion, with a high selectivity of 62.5 % for gasoline in total products. Molecular dynamic simulations and model experiments revealed that the diffusion of water molecules through hydrophilic catalyst was bidirectional, while the diffusion through hydrophobic catalyst was unidirectional, which were crucial to tune the water‐gas shift reaction and control CO2 formation. This work provides a new fundamental understanding about the function of hydrophobic modification of catalysts in syngas conversion.

Published: July 2023

AbstractThe selective transition‐metal catalyzed C−F bond functionalization of inexpensive industrial fluorochemicals represents one of the most attractive approaches to valuable fluorinated compounds. However, the selective C(sp2)−F bond carbofunctionalization of refrigerant hydrofluoroolefins (HFOs) remains challenging. Here, we report a nickel‐catalyzed selective C(sp2)−F bond alkylation of HFO‐1234yf with alkylzinc reagents. The resulting 2‐trifluoromethylalkenes can serve as a versatile synthon for diversified transformations, including the anti‐Markovnikov type hydroalkylation and the synthesis of bioactive molecule analogues. Mechanistic studies reveal that lithium salt is essential to promote the oxidative addition of Ni0(Ln) to the C−F bond; the less electron‐rich N‐based ligands, such as bipyridine and pyridine‐oxazoline, feature comparable or even higher oxidative addition rates than the electron‐rich phosphine ligands; the strong σ‐donating phosphine ligands, such as PMe3, are detrimental to transmetallation, but the less electron‐rich and bulky N‐based ligands, such as pyridine‐oxazoline, facilitate transmetallation and reductive elimination to form the final product.

AbstractElectrochemical CO2 reduction (CO2R) in acidic media with Cu‐based catalysts tends to suffer from lowered selectivity towards multicarbon products. This could in principle be mitigated using tandem catalysis, whereby the *CO coverage on Cu is increased by introducing a CO generating catalyst (e.g. Ag) in close proximity. Although this has seen significant success in neutral/alkaline media, here we report that such a strategy becomes impeded in acidic electrolyte. This was investigated through the co‐reduction of 13CO2/12CO mixtures using a series of Cu and CuAg catalysts. These experiments provide strong evidence for the occurrence of tandem catalysis in neutral media and its curtailment under acidic conditions. Density functional theory simulations suggest that the presence of H3O+ weakens the *CO binding energy of Cu, preventing effective utilization of tandem‐supplied CO. Our findings also provide other unanticipated insights into the tandem catalysis reaction pathway and important design considerations for effective CO2R in acidic media.
Autohydrolysis of Diglycine‐Activated Succinic Esters Boosts Cellular Uptake
Authors: Guo Jiaqi , Tan Weiyi , He Hongjian , Xu Bing 
Published: July 2023

AbstractRapid cellular uptake of synthetic molecules remains a challenge, and the motif frequently employed to generate prodrugs, succinic ester, unfortunately lowers the efficacy of the desired drugs due to their slow ester hydrolysis and low cell entry. Here we show that succinic ester‐containing diglycine drastically boosts the cellular uptake of supramolecular assemblies or prodrugs. Specifically, autohydrolysis of the diglycine‐activated succinic esters turns the nanofibers of the conjugates of succinic ester and self‐assembling motif into nanoparticles for fast cellular uptake. The autohydrolysis of diglycine‐activated succinic esters and drug conjugates also restores the efficacy of the drugs. 2D nuclear magnetic resonance (NMR) suggests that a “U‐turn” of diglycine favors intramolecular hydrolysis of diglycine‐activated succinic esters to promote autohydrolysis. As an example of rapid autohydrolysis of diglycine‐activated succinic esters for instant cellular uptake, this work illustrates a nonenzymatic bond cleavage approach to develop effective therapeutics for intracellular targeting.

AbstractTwo‐dimensional (2D)‐halide perovskites have been enriched over recent years to offer remarkable features from diverse chemical structures and environmental stability endowed with exciting functionalities in photoelectric detectors and phosphorescence systems. However, the low conversion efficiency of singlet to triplet in 2D hybrid halide perovskites reduces phosphorescence lifetimes. In this study, the long persistent luminescence of 2D all‐inorganic perovskites with a self‐assembled 2D interlayer galleries structure is investigated. The results show that the decay time of the long persistent luminescence increases from 450 s to 600 s, and the luminescence color changes from cyan to orange, and the thermal stability of photoluminescence enhances dramatically after replacing Cd2+ by appropriate Mn2+ ions in 2D Cs2CdCl4 Ruddlesden‐Popper phase perovskites. Furthermore, diversified anti‐counterfeiting modes are fabricated to highlight the promising applications of Cs2CdCl4 perovskite systems with tunable persistent luminescence in advanced anti‐counterfeiting. Therefore, our studies provide a novel model for realizing tunable long persistent luminescence of perovskite with 2D self‐assembled layered structure for advanced anti‐counterfeiting.

AbstractA comprehensive understanding of surface reconstruction was critical to developing high performance lattice oxygen oxidation mechanism (LOM) based perovskite electrocatalysts. Traditionally, the primary determining factor of the surface reconstruction process was believed to be the oxygen vacancy formation energy. Hence, most previous studies focused on optimizing composition to reduce the oxygen vacancy formation energy, which in turn facilitated the surface reconstruction process. Here, for the first time, we found that adding oxyanions (SO42−, CO32−, NO3−) into the electrolyte could effectively regulate the solid–liquid interface, significantly accelerating the surface reconstruction process and enhancing oxygen evolution reaction (OER) activities. Further studies indicated that the added oxyanions would adsorb onto the solid–liquid interface layer, disrupting the dynamic equilibrium between the adsorbed OH− ions and the OH− ions generated during surface reconstruction process. As such, the OH− ions generated during surface reconstruction process could be more readily released into the electrolyte, thereby leading to an acceleration of the surface reconstruction. Thus, it was expected that our finding would provide a new layer of understanding to the surface reconstruction process in LOM‐based perovskite electrocatalysts.

AbstractRecent work within neuroimaging consortia have aimed to identify reproducible, and often subtle, brain signatures of psychiatric or neurological conditions. To allow for high‐powered brain imaging analyses, it is often necessary to pool MR images that were acquired with different protocols across multiple scanners. Current retrospective harmonization techniques have shown promise in removing site‐related image variation. However, most statistical approaches may over‐correct for technical, scanning‐related, variation as they cannot distinguish between confounded image‐acquisition based variability and site‐related population variability. Such statistical methods often require that datasets contain subjects or patient groups with similar clinical or demographic information to isolate the acquisition‐based variability. To overcome this limitation, we consider site‐related magnetic resonance (MR) imaging harmonization as a style transfer problem rather than a domain transfer problem. Using a fully unsupervised deep‐learning framework based on a generative adversarial network (GAN), we show that MR images can be harmonized by inserting the style information encoded from a single reference image, without knowing their site/scanner labels a priori. We trained our model using data from five large‐scale multisite datasets with varied demographics. Results demonstrated that our style‐encoding model can harmonize MR images, and match intensity profiles, without relying on traveling subjects. This model also avoids the need to control for clinical, diagnostic, or demographic information. We highlight the effectiveness of our method for clinical research by comparing extracted cortical and subcortical features, brain‐age estimates, and case–control effect sizes before and after the harmonization. We showed that our harmonization removed the site‐related variances, while preserving the anatomical information and clinical meaningful patterns. We further demonstrated that with a diverse training set, our method successfully harmonized MR images collected from unseen scanners and protocols, suggesting a promising tool for ongoing collaborative studies.

Published: July 2023

AbstractThis paper reports the results of an experiment conducted before the 2021 regime change in Afghanistan that examined how different types of information strategies affected private sector support for a hypothetical peace agreement with the Taliban. We compared the impact of historical, pecuniary, and religious information on the stated preferences of Afghan business elites and employees in Kabul. The results show that historical information had less of an effect than pecuniary information on respondents' probability of accepting a peace agreement with the Taliban but a slightly larger effect than religious information. Although the context of the study has dramatically changed, the findings can inform practitioners and policymakers in mediating future peace negotiations in Afghanistan and elsewhere.

Published: July 2023

AbstractFetal gene therapy was first proposed toward the end of the 1990s when the field of gene therapy was, to quote the Gartner hype cycle, at its “peak of inflated expectations.” Gene therapy was still an immature field but over the ensuing decade, it matured and is now a clinical and market reality. The trajectory of treatment for several genetic diseases is toward earlier intervention. The ability, capacity, and the will to diagnose genetic disease early—in utero—improves day by day. A confluence of clinical trials now signposts a trajectory toward fetal gene therapy. In this review, we recount the history of fetal gene therapy in the context of the broader field, discuss advances in fetal surgery and diagnosis, and explore the full ambit of preclinical gene therapy for inherited metabolic disease.
Varietal and environmental influences on organoleptic and cooking quality of water yam (Dioscorea alata) landraces

Published: July 2023

AbstractBACKGROUNDYam is a major staple food that provides both energy (starch) and bioactive compounds. However, there is a lack of knowledge on its cooking quality. We have determined the cooking quality of five varieties of water yam (among those most appreciated by consumers), when they were steamed or boiled. The yams were grown in two contrasting locations with regard to pedoclimatic conditions.RESULTSRatio of length to mean circumference of the tuber, difficulty to peel, cooking time, color attributes, hardness of steamed pulp, and dry matter (DM) and starch contents significantly varied among varieties. Cooking time and hardness of the cooked pulp, either steamed or boiled, were higher for tubers grown at the drier location, with vertisols, than at the rainy one, with a ferralitic soil. The raw pulp was richer in starch at the rainy location. We found no correlation between either textural properties or DM and the cooking time. A slight (r = 0.44) but significant correlation was recorded between the DM of the raw pulp and the hardness of the steamed product.CONCLUSIONWe propose a comprehensive multicriteria approach for determination of yam cooking quality, textural properties, color attributes and chemical composition, along with varietal and environmental influences. This approach takes into consideration the complexity of food quality, allows a better understanding of its determinants and provides a basis for useful guidelines for breeders. © 2023 The Authors.

Pixel Super‐Resolution Interference Pattern Sensing Via the Aliasing Effect for Laser Frequency Metrology

Published: July 2023

AbstractThe superposition of several optical beams with large mutual angles results in sub‐micrometer periodic patterns with a complex intensity, phase, and polarization structure. For high‐resolution imaging thereof, one often employs optical super‐resolution methods such as scanning nano‐particle imaging. Here, it is reported that by using a conventional arrayed image sensor in combination with 2D Fourier analysis, the periodicities of light fields much smaller than the pixel size can be resolved in a simple and compact setup, with a resolution far beyond the Nyquist limit set by the pixel size. The ability to resolve periodicities with spatial frequencies of ≈3 µm−1, 15 times higher than the pixel sampling frequency of 0.188 µm−1, is demonstrated. This is possible by analyzing high‐quality Fourier aliases in the first Brillouin zone. In order to obtain the absolute spatial frequencies of the interference patterns, simple rotation of the image sensor is sufficient, which modulates the effective pixel size and allows determination of the original Brillouin zone. Based on this method, wavelength sensing with a resolving power beyond 100,000 without any special equipment is demonstrated.

AbstractObjectiveThe goal of this study is to evaluate the sensitivity and specificity of computed tomography (CT) scans in the diagnosis of foreign body aspiration (FBA) in children, and to determine whether chest CT scans would reduce the need for diagnostic rigid bronchoscopies.Data SourcesMEDLINE, EMBASE, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for relevant articles and conference proceedings that were published in English through November 1, 2022.Review MethodsWe included prospective and retrospective studies comparing chest CT scans and rigid bronchoscopy for the diagnosis of FBA in pediatric patients (<16 years old). The pooled estimates of the sensitivity and specificity of the chest CT scan in the diagnosis of FBA were calculated using a fixed‐ or common‐effects analysis and a random‐effects analysis that accounts for heterogeneity if present. Forest plots were constructed to combine the evidence identified during the systematic review.ResultsEighteen articles (4178 patients) were included. The average age of the children was 2.26 (±0.75) years, and 65% (±5.64%) of them were boys. Cough was the most prevalent symptom upon presentation. The pooled analysis showed that the sensitivity of chest CT scan in detecting a foreign body in children was 99% (95% confidence interval, CI [97, 100]; I2 = 72%, τ2 = 0.0065, p < .01). The false negative rate was 1.8% (95% CI [0.3, 2.7]; I2 = 72%, p < .01). The specificity of chest CT scan was 92% (95% CI [83, 98]; I2 = 83%, τ2 = 0.0437, p < .01).ConclusionsChest CT scan is a sensitive and specific test for the diagnosis of FBA in the pediatric population. Its use can help to reduce unnecessary rigid bronchoscopies, especially in patients with a low clinical suspicion of aspiration. It should not be a replacement for the gold standard bronchoscopy, particularly in cases where there is a clear history and symptoms suggestive of aspiration.
