AbstractThe high‐performance detector that operates at the low‐photon‐energy range (≈meV) of the electromagnetic spectrum at room temperature remains in urgent demand for application in a variety of important sectors, including 6G communications, security, sensing, medicine, space science, etc. The vast range of 2D‐layered nanomaterials and their distinct layer structures provide an ideal foundation for the manufacture of sophisticated photodetectors and detectors with convenient fabrication methods. In this paper, the direct detection of terahertz waveband dominated by the bolometer effect and photo‐thermoelectric effect is demonstrated, which is endowed with a versatile integration of 2H‐NbSe2 in terms of planar and vertical van der Waals structures. This 2H‐NbSe2‐based device can detect broadband long wavelength due to the bolometer effect, and the van der Waals heterostructure‐based device exhibits excellent sensitivity and self‐powered photo‐thermoelectric conversion with high responsivity (>735 V W−1), low response time (<1 µs), as well as low noise equivalent power (NEP < 50 pW Hz−0.5) at room temperature. The photodetector engineers versatile detection mechanisms, displaying low‐energy photons on the hybrid integration of novel low‐dimensional materials and providing an opportunity for the practical application of energy harvesting.

Published: March 2023

AbstractThe monitoring of tissue regeneration is particularly important. However, most materials do not allow direct observation of the regeneration process in the cartilage layer. Here, using sulfhydryl polyhedral oligomeric silsesquioxane (POSS‐SH) as a nano‐construction platform, poly(ethylene glycol) (PEG), Kartogenin (KGN), hydrogenated soya phosphatidylcholine (HSPC), and fluorescein are linked through the “click chemistry” method to construct nanomaterial with fluorescence visualization for cartilage repair: POSS linked with PEG, KGN, HSPC, and fluorescein (PPKHF). PPKHF nanoparticles are encapsulated with hyaluronic acid methacryloyl to prepare PPKHF‐loaded microfluidic hyaluronic acid methacrylate spheres (MHS@PPKHF) for in situ injection into the joint cavity using microfluidic technology. MHS@PPKHF forms a buffer lubricant layer in the joint space to reduce friction between articular cartilages, while releasing encapsulated positively charged PPKHF to the deep cartilage through electromagnetic force, facilitating visualization of the location of the drug via fluorescence. Moreover, PPKHF facilitates differentiation of bone marrow mesenchymal stem cells into chondrocytes, which are located in the subchondral bone. In animal experiment, the material accelerates cartilage regeneration while allowing monitoring of cartilage layer repair progression via fluorescence signals. Thus, these POSS‐based micro–nano hydrogel microspheres can be used for cartilage regeneration and monitoring and potentially for clinical osteoarthritis therapy.

AbstractMonitoring food retail stock‐outs or the unplanned unavailability of certain food items for purchase assists policymakers in responding to food supply chain disruptions. This study focuses on identifying food stock‐outs using store‐level scanner data on US grocery store sales during the COVID‐19 pandemic in 2020. The total median stock‐out rates of fixed‐weight items increased by approximately 130% after March 15, 2020. Categories such as meat and poultry products, some convenience and frozen foods, baby formula, and carbonated beverages had the highest stock‐out rates. The analysis also explores the relationship between stock‐out rates, sales increases, and food prices during the pandemic.

Published: March 2023

AbstractA mild Pd‐catalyzed Tsuji‐Trost reaction of allylic alcohols with an amine nucleophile in water media was developed, leading to the green synthesis of the valuable allylic amines. This new method requires no chemical activators and sophisticated soluble ligands, and can be easily scaled up in gram scale and be readily extended to the gram scale synthesis of Naftifine, one of the best‐selling antifungal drugs, showing the practical value of this new method.

Published: March 2023

AbstractChronic emesis (CE) is a poorly understood condition in human and nonhuman primates that negatively impacts the quality of life. Early identification of risk factors for the development of CE is likely to improve the ability to manage CE cases successfully and is, therefore, desirable. Using a case‐control study, we reviewed the necropsy records of the California National Primate Research Center and identified 24 animals with recorded CE, defined as five or more incidents of emesis in 1 month. A group of 89 healthy rhesus macaques (Macaca mulatta), comparable in age and percent time housed indoors, was similarly identified. Next, we investigated the association between the occurrence of CE during later stages of life after infancy and the behavioral temperament scores attained in infancy, age, sex, birth location, rearing condition, history of self‐injurious behavior (SIB), and the number of lifetime sedation events. Our analysis revealed that CE was associated with degrees of temperament constructs obtained in infancy (data was available for n = 113), such as Confidence (odds ratio (OR) = 0.45, 95% CI: 0.18, 1.08, p = 0.07), Gentleness (OR = 0.47, 95% CI: 0.23, 0.96, p = 0.03), Nervousness (OR = 2.04, 95% CI: 0.98, 4.23, p = 0.05), and Vigilance (OR = 0.36, 95% CI: 015, 0.87, p = 0.02), suggesting that CE is linked to behavioral phenomenon measured in early life, long before it becomes a medical concern. Our data suggest that CE was positively correlated with a history of SIB (OR 4.26, 95% CI: 0.98, 18.47, p = 0.04). Accurate prediction of CE can then assist behavioral and colony management professionals in making informed decisions regarding the care of animals at risk of developing CE. Moreover, the novel information we reported here could have valuable implications in human medicine, where gastrointestinal distress is a common complaint affecting a person's quality of life.

AbstractAustralian governments have used vaccine mandates to drive high uptake of routine childhood vaccines and adult Coronavirus Disease 2019 (COVID‐19) and influenza vaccines. We sought to understand the attitudes of Western Australian parents regarding mandating COVID‐19 vaccines for children, interviewing 44 parents of children aged up to 18 years between May and December 2021. Transcripts were analysed to ascertain parents' attitudes and sources of reasoning. Over half of the parents supported COVID‐19 vaccine mandates for children, while the rest had opposing, nuanced or indifferent views. Participants invoked community and health‐related reasoning; policy and government‐related reasoning; and concerns based on practical implementation. There was a high degree of consistency in parents' attitudes toward COVID‐19 vaccines and whether they supported mandating them for children, although some who planned to delay vaccination nevertheless supported the idea of mandates. Some participants reported that a mandate would prompt them to vaccinate, but others were willing to accept the consequences of keeping their children unvaccinated, or said that a mandate would not affect them as they would vaccinate regardless. Understanding how parents think and feel about mandating COVID‐19 vaccines with educational exclusions or financial penalties is critical to inform policymakers, who may consider these strategies for future pandemic vaccines.

Published: March 2023

AbstractIntroducing vortices into an Airy beam by the interference between the lobes of the Airy beam for the first time, the modulation of Airy vortices is experimentally and theoretically investigated by electromagnetically induced transparency (EIT) effect and changing the number of side lobes of the Airy beam. The formation and disappearance of vortices in Airy beams can be caused by changing the number of side lobes. The EIT effect can induce the movement of vortex phase singularity by regulating the intensities of lobes in Airy beams. However, changing the number of side lobes can change the energy distribution of the lobes through the energy flow due to the self‐healing of Airy beams, thus causing the displacement of vortex phase singularity. In addition, the simulation of the Poynting vector shows that the less the side lobes are blocked, the more energy can be retained in the main lobe and the unblocked side lobes, so that the overall shape of the Airy beam can be better maintained. Such studies provide a new method to acquire and adjust Airy vortex beams and can be applied in the realm of optical micromanipulation.

Published: March 2023

AbstractPuromycin derivatives containing an emissive thieno[3,4‐d]‐pyrimidine core, modified with azetidine and 3,3‐difluoroazetidine as Me2N surrogates, exhibit translation inhibition and bactericidal activity similar to the natural antibiotic. The analogues are capable of cellular puromycylation of nascent peptides, generating emissive products without any follow‐up chemistry. The 3,3‐difluoroazetidine‐containing analogue is shown to fluorescently label newly translated peptides and be visualized in both live and fixed HEK293T cells and rat hippocampal neurons.

Published: March 2023

AbstractIn‐cell NMR spectroscopy is an effective tool for observing proteins at atomic resolution in their native cellular environment. However, its utility is limited by its low sensitivity and the extensive line broadening caused by nonspecific interactions in the cells, which is even more pronounced in human cells due to the difficulty of overexpressing or delivering high concentrations of isotopically labeled proteins. Here, we present a high‐sensitivity tag (wPSP‐6F) containing two trifluoromethyl groups that can efficiently label globular proteins with molecular weights in the 6–40 kDa range under mild conditions. This tag allowed us to detect globular proteins in human cells at concentrations as low as 1.0 μM, which would not have been achievable with 15N or 3‐fluorotyrosine labeling. Moreover, we detected conformational changes and interactions of proteins in the cellular environment. The new sensitive 19F NMR tag may significantly expand the scope of protein NMR in human cells.

Published: March 2023

AbstractImproving kinetics of solid‐state sulfide conversion in sulfur cathodes can enhance sulfur utilization of metal‐sulfur batteries. However, fundamental understanding of the solid‐state conversion remains to be achieved. Here, taking potassium‐sulfur batteries as a model system, we for the first time report the reducing overpotential of solid‐state sulfide conversion via the meta‐stable S32− intermediates on transition metal single‐atom sulfur hosts. The catalytic sulfur host containing Cu single atoms demonstrates high capacities of 1595 and 1226 mAh g−1 at current densities of 335 and 1675 mA g−1, respectively, with stable Coulombic efficiency of ≈100 %. Combined spectroscopic characterizations and theoretical computations reveal that the relatively weak Cu‐S bonding results in low overpotential of solid‐state sulfide conversion and high sulfur utilization. The elucidation of solid‐state sulfide conversion mechanism can direct the exploration of highly efficient metal‐sulfur batteries.

Published: March 2023

AbstractDespite their high output voltage and safety advantages, rechargeable alkaline nickel‐zinc batteries face significant challenges associated with the cathodic side reaction of oxygen evolution, which results in low energy efficiency (EE) and poor stability. Herein, we propose to leverage the side oxygen evolution reaction (OER) in nickel‐zinc batteries by coupling electrocatalysts for oxygen reduction reactions (ORR) in the cathode, thus constructing an air breathing cathode. Such a novel battery (Ni‐ZnAB), designed in a pouch‐type cell with a lean electrolyte, exhibits an outstanding EE of 85 % and a long cycle life of 100 cycles at 2 mA cm−2, which are significantly superior to those of traditional Ni‐Zn batteries (54 %, 50 cycles). Compared to Ni‐Zn, the enhanced EE of Ni‐ZnAB is attributed to the contribution from ORR, while the improved cycling stability is because the stability of the anode, cathode and electrolyte are also enhanced in Ni‐ZnAB. Furthermore, an ultrahigh stability of 500 cycles with an average EE of 84 % at 2 mA cm−2 was achieved using a mold cell with rich electrolyte, demonstrating the strong application potential of Ni‐ZnAB.

Published: March 2023

AbstractLow‐valent metal–organic frameworks (LVMOFs) and related materials have gained interest due to their potential applications in heterogeneous catalysis. However, of the few LVMOFs that have been reported, none have shown catalytic activity. Herein, a low‐valent metal‐organic material constructed from phosphine linkers and IrI nodes is reported. This material is effectively a crystalline, insoluble analogue of Vaska's complex. As such, the material reversibly binds O2 and catalyzes the reductive formation of enamines from amides.

Published: March 2023

AbstractWe demonstrate an innovative technique to achieve organic 2D and 3D waveguides with peculiar shapes from an acicular, stimuli‐responsive molecular crystal, (2Z,2′Z)‐3,3′‐(anthracene‐9,10‐diyl)bis(2‐(3,5‐bis(trifluoromethyl)phenylacrylonitrile), Ant‐CF3. The greenish‐yellow fluorescent (FL) Ant‐CF3 molecular crystals exhibit laser power‐dependent permanent mechanical bending in 2D and 3D. Investigation of a single‐crystal using spatially‐resolved Raman/FL/electron microscopy, and theoretical calculations revealed photothermal (Z,E)/(E,E) isomerization‐assisted transition from crystalline to amorphous phase at the laser‐exposed regions. This phenomenon facilitates the dimension engineering of a 1D crystal waveguide into 2D waveguide on a substrate or a 3D waveguide in free space. The bends can be used as interconnection points to couple different optical elements. The presented technique has broader implications in organic photonics and other crystal‐related photonic technologies.
Modeling complex AGN media in X‐rays with skirt
Authors: Vander Meulen Bert , Camps Peter , Stalevski Marko , Baes Maarten 
Published: March 2023

AbstractWe present the new X‐ray functionalities of the skirt radiative transfer code, forming an advanced tool to study cold dusty gas in active galactic nuclei (AGN), with a particular focus on complex three‐dimensional transfer media. Focusing on the X‐ray broadband spectra of obscured AGN, skirt incorporates scattering on free electrons, absorption and fluorescence by cold gas, scattering on bound electrons, as well as absorption and scattering by dust. This goes beyond the X‐ray physical processes that are currently implemented in most spectral models for fitting distant reflection in AGN. With the introduction of these X‐ray physics, we obtain a high‐performance radiative transfer code that can model intricate multi‐phase AGN media with complex geometries in X‐rays, which furthermore supports advanced kinematics and allows for self‐consistent model predictions from infrared to X‐ray energies.
Norvancomycin plasma concentration monitoring in hemodialysis patients with end stage kidney disease: A retrospective cohort study

Published: March 2023

AbstractBlood concentration monitoring plays an important role in the rational use of norvancomycin. However, the reference interval for the norvancomycin plasma concentration in the treatment of infections in hemodialysis patients with end stage kidney disease is undefined. To determine the safe and effective interval for the norvancomycin plasma trough concentration, 39 patients treated with hemodialysis and norvancomycin were analyzed retrospectively. The norvancomycin plasma concentration before hemodialysis was tested as the trough concentration. The associations of the norvancomycin trough concentration with efficacy and adverse reactions were evaluated. No norvancomycin concentration above 20 μg/mL was detected. The trough concentration, but not the dose, had a significant effect on the anti‐infectious efficacy. Compared with the low norvancomycin trough concentration group (<9.30 μg/mL), the high concentration group (9.30–20.0 μg/mL) had improved efficacy (OR = 15.45, p < 0.01) with similar side effects (OR = 0.5417, p = 0.4069). It is beneficial to maintain the norvancomycin trough concentration at 9.30–20.0 μg/mL to achieve a good anti‐infectious effect in hemodialysis patients with end stage kidney disease. Plasma concentration monitoring provides a data basis for the individual treatment of infections with norvancomycin in hemodialysis patients.
Prior behavior and wording of norm nudge requests shape compliance and reciprocity
Authors: Pittarello Andrea , Schmidt Thekla , Segel Assaf , Mayo Ruth 
Published: March 2023

AbstractWe examined the effect of explicit norm nudge requests for compliance in a field study on workplace dishonesty and three controlled experiments on reciprocity. The requests were presented either with affirmation (e.g., “please pay” and “please remember to pay”) or negation (e.g., “please, do not forget to pay”) and solicited by either one person or three people who were also the beneficiaries of compliance. We also explored how these requests affected first time and repeated behaviors. We found no effect of the number of people soliciting the requests. However, we did find that for first‐time behaviors, any request increased compliance compared with no request, and those worded with affirmation were more effective than those worded with negation. We replicated this pattern in repeated behaviors—both at the group and at the individual level—but only when the initial compliance, before the request, was low. Importantly, no increase emerged when individuals did not receive requests, showing that requests only, and not regression to the mean, explained the effect.

Published: March 2023

AbstractOlanzapine (OLZ) is an antipsychotic agent and is a thienobenzodiazepine derivative. It is used either in combination with other drugs like carbamazepine, simvastatin, and clozapine or as a single drug. The present work is mainly focused on various approaches for OLZ analysis in bulk drugs as well as on their pharmaceutical formulations. It is also focused on various bioanalytical methods used for analysis. Our survey showed that many analytical techniques were carried out using UV spectrophotometry, MS, LC–MS/MS techniques, and chromatographic techniques like HPLC and high‐performance thin layer chromatography in both bulk and solid dosage forms. Bioanalytical techniques were also performed using human plasma or serum. The analysis was carried out either for a single drug or for a combination of drugs. This review shows the rate of use of the different methodologies for OLZ analysis. A considerable amount of information was collected and utilized for the strategies.
