AbstractTandem nitrate electroreduction reaction (NO3−RR) is a promising method for green ammonia (NH3) synthesis. However, the mismatched kinetics processes between NO3−‐to‐NO2− and NO2−‐to‐NH3 results in poor selectivity for NH3 and excess NO2− evolution in electrolyte solution. Herein, a Ni2+ substitution strategy for developing oxide heterostructure in Co/Fe layered double oxides (LDOs) was designed and employed as tandem electrocataltysts for NO3−RR. (Co0.83Ni0.16)2Fe exhibited a high NH3 yield rate of 50.4 mg ⋅ cm−2 ⋅ h−1 with a Faradaic efficiency of 97.8 % at −0.42 V vs. reversible hydrogen electrode (RHE) in a pulsed electrolysis test. By combining with in situ/operando characterization technologies and theoretical calculations, we observed the strong selectivity of NH3 evolution over (Co0.83Ni0.16)2Fe, with Ni playing a dual role in NO3−RR by i) modifying the electronic behavior of Co, and ii) serving as complementary site for active hydrogen (*H) supply. Therefore, the adsorption capacity of *NO2 and its subsequent hydrogenation on the Co sites became more thermodynamically feasible. This study shows that Ni substitution promotes the kinetics of the NO3−RR and provides insights into the design of tandem electrocatalysts for NH3 evolution.

AbstractEfficient plastic recycling processes are crucial for the production of value‐added products or intermediates. Here, we present a multicatalytic route that allows the degradation of nitrile‐butadiene rubber, cross‐metathesis of the formed oligomers, and polymerization of the resulting dicarboxylic acids with bio‐based diols, providing direct access to unsaturated polyesters. This one‐pot approach combines the use of commercially available catalysts that are active and selective under mild conditions to synthesize renewable copolymers without the need to isolate intermediates.
Self‐relevance enhances susceptibility to false memory

Published: January 2024

AbstractEyewitness testimony serves as important evidence in the legal system. Eyewitnesses of a crime can be either the victims themselves—for whom the experience is highly self‐referential—or can be bystanders who witness and thus encode the crime in relation to others. There is a gap in past research investigating whether processing information in relation to oneself versus others would later impact people's suggestibility to misleading information. In two experiments (Ns = 68 and 122) with Dutch and Chinese samples, we assessed whether self‐reference of a crime event (i.e., victim vs. bystander) affected their susceptibility to false memory creation. Using a misinformation procedure, we photoshopped half of the participants' photographs into a crime slideshow so that they saw themselves as victims of a nonviolent crime, while others watched the slideshow as mock bystander witnesses. In both experiments, participants displayed a self‐enhanced suggestibility effect: Participants who viewed themselves as victims created more false memories after receiving misinformation than those who witnessed the same crime as bystanders. These findings suggest that self‐reference might constitute a hitherto new risk factor in the formation of false memories when evaluating eyewitness memory reports.

Published: January 2024

AbstractDarwinian evolution, including the selection of the fittest species under given environmental conditions, is a major milestone in the development of synthetic living systems. In this regard, generalist or specialist behavior (the ability to replicate in a broader or narrower, more specific food environment) are of importance. Here we demonstrate generalist and specialist behavior in dynamic combinatorial libraries composed of a peptide‐based and an oligo(ethylene glycol) based building block. Three different sets of macrocyclic replicators could be distinguished based on their supramolecular organization: two prepared from a single building block as well as one prepared from an equimolar mixture of them. Peptide‐containing hexamer replicators were found to be generalists, i. e. they could replicate in a broad range of food niches, whereas the octamer peptide‐based replicator and hexameric ethyleneoxide‐based replicator were proven to be specialists, i. e. they only replicate in very specific food niches that correspond to their composition. However, sequence specificity cannot be demonstrated for either of the generalist replicators. The generalist versus specialist nature of these replicators was linked to their supramolecular organization. Assembly modes that accommodate structurally different building blocks lead to generalist replicators, while assembly modes that are more restrictive yield specialist replicators.
Covalent Post‐Synthetic Modification of Metal‐Organic Cages: Concepts and Recent Progress

Published: January 2024

AbstractMetal‐organic cages (MOCs) are supramolecular coordination complexes that have internal cavities for hosting guest molecules and exhibiting various properties. However, the functions of MOCs are limited by the choice of the building blocks. Post‐synthetic modification (PSM) is a technique that can introduce new functional groups and replace existing ones on the MOCs without changing their geometry. Among many PSM methods, covalent PSM is a promising approach to modify MOCs with tailored structures and functions. Covalent PSM can be applied to either the internal cavity or the external surface of the MOCs, depending on the functionality expected to be customized. However, there are still some challenges and limitations in the field of covalent PSM of MOCs, such as the balance between the stability of MOCs and the harshness of organic reactions involved in covalent PSMs. This concept article introduces the organic reaction types involved in covalent PSM of MOCs, their new applications after modification, and summarizes and provides an outlook of this research field.
Optimization and modelling of pravastatin recovery from aqueous solutions using reactive extraction methodology
Authors: Yetisen Mehmet , Uslu Hasan , Baltacioglu Cem 
Published: January 2024

AbstractThis research endeavour primarily aimed to optimize and establish a model for the recovery of pravastatin, a well‐known statin drug recognized for its cholesterol‐lowering properties, from aqueous solutions using reactive extraction. This study used the Box–Behnken design to investigate extraction parameters and create a concise model equation illustrating the relationship between variables and responses. The investigation showed a strong agreement between the model equation and experimental outcomes. It highlighted a positive correlation, demonstrating that higher concentrations of reactant and pravastatin led to notable improvements in extraction efficiency. Two out of 90 experiments had extraction efficiencies below 10%, both with constant factors except for solvent type, while 14 experiments exceeding 80% efficiency highlighted the positive impact of a 50% reactant concentration on extraction efficiency. According to a statistical second‐order polynomial, the predicted extraction efficiency stands at 75.14%. In the culminating phase of the study, optimal extraction conditions were meticulously determined, resulting in the identification of an optimal set of parameters: a pravastatin concentration of 35 mg · L−1, an adogen concentration of 20.91% (v/v), and a butanol phase ratio of 0.2% (v/v). Under optimal conditions, the experimental extraction efficiency reached 72.69%, closely aligning with values predicted through numerical optimization employing response surface methodology.

Published: January 2024

AbstractBackgroundFood hypersensitivity (FHS) management requires daily risk assessments of all food and drinks consumed to prevent unpleasant and potentially fatal adverse reactions. Most research has focussed on food allergy in children and families. Little is known about the impact on adults or those with other FHS, such as food intolerance or coeliac disease. This study assessed differences in practices and risk assessment behaviours when eating out for adults with FHS.MethodsAdult UK residents (N = 930; 820 females, 90 males; 95% White; mean age 50 years [±16.6SD]), with food allergy (18%), food intolerance (23%) coeliac disease (44%) or multiple FHS (15%) completed an online survey.ResultsAdults checked information to identify foods causing a reaction always or most of the time when eating out. However, adults with food intolerance reported checking significantly less often than adults with other FHS (all ps < 0.001). Adults reporting more severe FHS, medical rather than self‐diagnosis of FHS, previous anaphylaxis, had called an ambulance or been in hospital due to a reaction checked information significantly more often (all ps < 0.001), but were also less confident in the information provided (all ps < 0.05). Adults with allergy, coeliac disease or multiple FHS were also less confident in written and verbal information provided than those with food intolerance (p < 0.01). The type of FHS, greater perceived severity of FHS and having a medical diagnosis consistently predicted risk assessment behaviours when eating out (all ps < 0.001).ConclusionClinicians, patients and the food industry should be aware that the type of FHS, patient‐perceived severity and past experience of reactions affect risk assessment behaviours when eating out. This should be considered when providing clinical advice and emergency plans.
Structural Development of Androgen Receptor Antagonists Using Phenylferrocene Framework as a Hydrophobic Pharmacophore

Published: January 2024

AbstractWe previously identified nitrophenylferrocenes and cyanophenylferrocenes as promising lead structures of novel androgen receptor (AR) antagonists, based on the structural similarity between ferrocene and the steroidal skeleton. In the present research, we explored the structure‐activity relationship (SAR) of phenylferrocene derivatives. Introduction of a hydrophobic substituent such as a chlorine atom at the 2‐position or 3‐position of phenylferrocene derivatives significantly increased the antagonistic activity toward wild‐type AR, and among the synthesized compounds, 3‐chloro‐4‐cyanophenylferrocene (29) exhibited the most potent anti‐proliferative activity toward the androgen‐dependent growth of SC‐3 cells expressing wild‐type AR (IC50 14 nM). Like conventional antiandrogens such as hydroxyflutamide, the major active metabolite of flutamide, compound 29 exhibited agonistic activity toward T877A‐AR, a mutant AR expressed in human prostate cancer cell line LNCaP. Notably, however, the 2‐chloro isomer 27 showed potent antagonistic activity toward wild‐type AR (IC50 49 nM) and also exhibited antagonistic activity toward T877A‐AR. Our SAR data should prove helpful for the development of new‐generation AR antagonists based on phenylferrocene as candidate agents to treat drug‐resistant prostate cancer.

AbstractThe Covid‐19 crisis has led to a massive surge in the use of surgical masks worldwide, causing risks of shortages and high pollution. Reusing the masks may be promising to reduce such risks, especially since various decontamination techniques are being investigated. In this study, the thermal degradation of surgical masks was investigated using X‐ray‐based techniques such as XRD and XPS. Additional characterization was performed using scanning electron microscopy and contact angle measurements. XRD experiments reveal an increase in both crystal size and crystallinity of the mask with temperature until it is destroyed at 160 °C. However, XPS results show that there was no significant change in the surface chemistry of the mask, as no other chemical element has been detected in the mask heated up. Breathability has been proven compliant with standards until 150 °C.
Flash Organometallic Catalysis Uncovered by Continuous Microfluidic Devices
Authors: Guan Fanfu , Wen Jialin 
Published: January 2024

AbstractThe flash organometallic catalysis is a new concept that refers to the study of fast and controlled organometallic catalytic reactions by using microfluidic devices. Flash reactions’ kinetics (ms‐s scale) is often ignored due to the lack of proper research tool in organometallic chemistry. The development of microfluidic systems offers the opportunity to discover under‐studied mechanisms and new reactions. In this concept, the basic theory of kinetic measurement in a microreactor is briefly reviewed and then two examples on studying flash organometallic catalytic transformation are introduced. One example is the discovery of a highly active palladium catalytic species for Suzuki Coupling and the other example is the study of a neglected isomerization catalytic cycle with a time scale of seconds before isomerization‐hydroformylation by customized microfluidic devices. The last part is summary and prospect of this new area. Customizing a microfluidic device with good engineering design for a target reaction supports flash reactions’ kinetic experimentation and could become a general strategy in chemistry lab.
Vendor sustainability performance and corporate customers' supplier selection
Authors: Cui Xiaoyu , Qi Baolei , Hussain Muhammad Jameel 
Published: January 2024

AbstractThis study investigates the impact of potential suppliers' sustainability performance (measured by environmental, social, and governance performance) on customer firms' supplier selection decisions. Our findings suggest that potential suppliers (vendors) with better sustainability performance are more likely to be selected as actual suppliers. Moreover, we find that customer firms with better sustainability performance, those operating in competitive industries, and state‐owned customer firms are more inclined to opt for sustainable suppliers. Furthermore, our analyses indicate that the positive influence of vendors' sustainability performance on the likelihood of being selected is more significant for vendors who hold non‐leading industrial positions or face high uncertainty. In addition, by focusing on actual customer‐supplier relationships, we find that customer firms benefit from collaborating with more sustainable suppliers. Overall, this study provides valuable insights into the role of corporate sustainability in supply chain management.

AbstractIn this letter, a novel secret merchant‐4 (SM4) cryptographic circuit implementation is proposed against higher order power analysis attacks (PAAs). Four different random number generators (RNGs) are embedded into the SM4 architecture for breaking the correlation between the processed data and monitored power dissipation against PAAs. Firstly, fake keys are created by the first RNG to scramble the critical information related with the actual secret key. Furthermore, the second RNG controls the implementations of substitution boxes (Sboxes) with composite fields or look‐up tables randomly while the third RNG randomizes the substitution locations with respect to these Sboxes. Ultimately, the fourth RNG randomly swaps the behaviors of the fake SM4 and true SM4 to further break the critical correlation. Under the assistance of the four embedded RNGs, the proposed SM4 cryptographic architecture is capable of resisting against fourth‐order PAAs effectively with a 300 Mbps throughput and 165,354  m2area after synthesizing in the TSMC 90 nm process design kits (PDK).
Challenges in applying principles from cognitive science to the design of a school mathematics curriculum

Published: January 2024

AbstractThere are increasingly frequent calls for school mathematics curricula to be informed by robust research evidence. One approach to achieving this is designing evidence‐informed learning and teaching resources for the classroom. In this paper, we reflect on our experiences of designing a free and fully resourced complete set of secondary mathematics curriculum materials. We explore in detail the challenges we have encountered in our attempts to apply principles from the cognitive theory of multimedia learning. We focus on tensions we have experienced when simultaneously applying multiple principles and balancing these with other educational considerations. Specifically, we consider trade‐offs between redundancy versus clarity, seductive details versus richness, personalisation and emotional design versus abstraction, spatial contiguity and signalling versus parsimony, and pre‐training and worked examples versus exploration. We examine the choices and dilemmas we faced, and illustrate our emerging attempts to resolve these tensions through presenting multiple examples from our design work. We conclude with recommendations about how tensions among these design principles might be navigated in curriculum design and we suggest possible avenues for further research in this area.
Co‐occurring orchid species associated with different low‐abundance mycorrhizal fungi from the soil in a high‐diversity conservation area in Denmark

Published: January 2024

AbstractPlant–fungal interactions are ubiquitous across ecosystems and contribute significantly to plant ecology and evolution. All orchids form obligate symbiotic relationships with specific fungi for germination and early growth, and the distribution of terrestrial orchid species has been linked to occurrence and abundance of specific orchid mycorrhizal fungi (OMF) in the soil. The availability of OMF can therefore be a habitat requirement that is relevant to consider when establishing management and conservation strategies for threatened orchid species, but knowledge on the spatial distribution of OMF in soil is limited. We here studied the mycorrhizal associations of three terrestrial orchid species (Anacamptis pyramidalis, Orchis purpurea and Platanthera chlorantha) found in a local orchid diversity hotspot in eastern Denmark, and investigated the abundance of the identified mycorrhizal fungi in the surrounding soil. We applied ITS metabarcoding to samples of orchid roots, rhizosphere soil and bulk soil collected at three localities, supplemented with standard barcoding of root samples with OMF specific primers, and detected 22 Operational Taxonomic Units (OTUs) putatively identified as OMF. The three orchid species displayed different patterns of OMF associations, supporting the theory that association with specific fungi constitutes part of an orchid's ecological niche allowing co‐occurrence of many species in orchid‐rich habitats. The identified mycorrhizal partners in the basidiomycete families Tulasnellaceae and Ceratobasidiaceae (Cantharallales) were detected in low abundance in rhizosphere soil, and appeared almost absent from bulk soil at the localities. This finding highlights our limited knowledge of the ecology and trophic mode of OMF outside orchid tissues, as well as challenges in the detection of specific OMF with standard methods. Potential implications for management and conservation strategies are discussed.

AbstractBrønsted acid mediated [3+2] cycloaddition of coumarin‐based enamines with 3‐ylidene oxindoles generated in situ from 3‐hydroxy‐3‐aroylmethyl oxindoles enabled the synthesis of polyheterocyclic compounds with a pyrrolocoumarin core structure in a highly regioselective manner. The synthetic procedure is highly efficient and metal‐free, and no chromatographic purification of the products is required. The chromenopyrrole derivatives bearing an oxindole moiety formed as rapidly interconverting rotamers.
Hedging securities and Silicon Valley Bank idiosyncrasies
Authors: Kim Raymond 
Published: January 2024

AbstractHedging requires adequacy and timing. This paper finds that banks did not systematically ignore balance‐sheet risks like Silicon Valley Bank (SVB), and instead exercised risk management by asymmetrically increasing hedging activity when security losses increase and scaling back hedging activity as security losses reverse. Banks also hedge against bank runs when risk increases due to a combination of security losses and funding risks from unsecured deposits. Findings suggest SVB's mistakes are idiosyncratic. Results suggest that nonstress test banks target balance‐sheet risks when hedging, stabilizing themselves from interest rate shocks transmitted through fixed‐income securities. Scrutiny of rules‐based outliers like SVB is preferable to increased regulatory burden for all nonstress test banks.
