AbstractBoron‐enriched scaffolds have demonstrated unique features and promising performance in the field of catalysis towards the activation of small gas molecules. However, there is still a lack of facile approaches capable of achieving high B doping and abundant porous channels in the targeted catalysts. Herein, construction of boron‐ and nitrogen‐enriched nanoporous π‐conjugated networks (BN‐NCNs) was achieved via a facile ionothermal polymerization procedure with hexaazatriphenylenehexacarbonitrile [HAT(CN)6] sodium borohydride as the starting materials. The as‐produced BN‐NCN scaffolds were featured by high heteroatoms doping (B up to 23 wt. % and N: up to 17 wt. %) and permanent porosity (surface area up to 759 m2 g−1 mainly contributed by micropores). With the unsaturated bonded B species acting as the active Lewis acid sites and defected N species acting as the active Lewis base sites, those BN‐NCNs delivered attractive catalytic performance towards H2 activation/dissociation in both gaseous and liquid phase, acting as efficient metal‐free heterogeneous frustrated Lewis pairs (FLPs) catalysts in hydrogenation procedures.

AbstractSluggish storage kinetics and insufficient performance are the major challenges that restrict the transition metal dichalcogenides (TMDs) applied for zinc ion storage, especially at the extreme temperature conditions. Herein, a multiscale interface structure‐integrated modulation concept was presented, to unlock the omnidirectional storage kinetics‐enhanced porous VSe2−x⋅n H2O host. Theory research indicated that the co‐modulation of H2O intercalation and selenium vacancy enables enhancing the interfacial zinc ion capture ability and decreasing the zinc ion diffusion barrier. Moreover, an interfacial adsorption‐intercalation pseudocapacitive storage mechanism was uncovered. Such cathode displayed remarkable storage performance at the wide temperature range (−40–60 °C) in aqueous and solid electrolytes. In particular, it can retain a high specific capacity of 173 mAh g−1 after 5000 cycles at 10 A g−1, as well as a high energy density of 290 Wh kg−1 and a power density of 15.8 kW kg−1 at room temperature. Unexpectedly, a remarkably energy density of 465 Wh kg−1 and power density of 21.26 kW kg−1 at 60 °C also can be achieved, as well as 258 Wh kg−1 and 10.8 kW kg−1 at −20 °C. This work realizes a conceptual breakthrough for extending the interfacial storage limit of layered TMDs to construct all‐climate high‐performance Zn‐ion batteries.
When Weak Is Strong: A Plea for Low‐Affinity Binders for Optical Microscopy
Authors: Albertazzi Lorenzo , Heilemann Mike 
Published: May 2023

AbstractThe exploitation of low‐affinity molecular interactions in protein labeling is an emerging topic in optical microscopy. Such non‐covalent and low‐affinity interactions can be realized with various concepts from chemistry and for different molecule classes, and lead to a constant renewal of fluorescence signals at target sites. Further benefits are a versatile use across microscopy methods, in 3D, live and many‐target applications. In recent years, several classes of low‐affinity labels were developed and a variety of powerful applications demonstrated. Still, this research field is underdeveloped, while the potential is huge.

Abstract[3]Radialene has a peculiar topology and cross‐conjugation system, representing a unique molecular scaffold in organic materials. Herein, we report a special class of stereoisomeric α‐cyano triaryl[3]radialenes (CTRs) that show concentration‐caused quenching in solution but emit red‐shifted and enhanced luminescence in the crystalline state. Clustering of multiple cyano groups and their through‐space interactions with the [3]radialene ring significantly extend π‐electron communication meanwhile rigidifying the propeller conformation multivalently, thus playing a key role behind the state‐dependent luminescence. These radialenes with a substantial electron affinity undergo a reversible electron transfer transition to anionic radicals with good stability, showing switching of photoabsorption, photoluminescence and electron spin resonance (ESR) signal. We also established proof‐of‐concept applications of CTRs for multimodal information encryption and chemical sensing.

Published: May 2023

AbstractGenipin (GP) as a natural crosslinker has gained much attention in the food industry on account of its high biocompatibility and safety. In this paper, chitosan (CS)‐soy protein isolate (SPI) crosslinked films were prepared using GP as a crosslinking agent. Crosslinking reaction with high contents of GP (0.03%, 0.05%) changed the rheological property of the film matrixes. The crosslinking degree was positively correlated with the content of GP, which was from 21.08 ± 3.95% of CS‐SPI‐1 to 39.66 ± 1.62% of CS‐SPI‐5. Fourier transform infrared spectroscopy spectra confirmed the crosslinking reaction. The X‐ray diffraction and scanning electron microscopy analyses indicated that the crosslinking reaction decreased the crystallinity degree and enhanced the surface roughness of CS‐SPI film, respectively. The crosslinking reaction did not significantly affect the thickness, moisture content and water solubility of CS‐SPI film. Crosslinked films presented better light barrier capacity. The tensile strength (TS) of CS‐SPI‐1 was increased by 50%, however, further increasing the contents of GP (0.03%, 0.05%) reduced the TS of the crosslinked films. With the increasing incorporation with GP, the EAB was significantly decreased, while the modulus increased from 95.76 ± 25.78 to 508.78 ± 77.95 MPa. The crosslinking reaction improved the rigidity of CS‐SPI film. Low crosslinking degree could improve thermal stability of CS‐SPI, while higher GP addition (0.03%, 0.05%) decreased the thermal stability and prolonged the degradation time of the film in soil. The results indicated that low crosslinking reaction could improve the property of CS‐SPI film, enhancing its potential application in food packaging.

AbstractDeveloping green composites has received intense attention among the scientific community because of their ability to help alleviate the global environmental pollution challenges. This current work focused on preparing a bio‐based composite material with desirable performance using renewable materials like diatomaceous earth, and polylactic acid (PLA) with poly(butanediol adipate ester) prepolymer (PBAPU) as a compatibilizer. The composites were prepared by reactive mixing using an intensive mixer. Subsequently, the effects of the PBAPU content on the structure and properties of the composites were studied. From the test results, it was revealed that increasing the PBAPU content resulted in an increasing trend in the properties of the composites. For instance, the thermal stability of the composites was improved as the PBAPU content was increased, and the best thermal stability was obtained when 20 wt% PBAPU was added. In addition, the mechanical properties test results showed that the elongation at break and impact strength of the composites increased with increasing PBAPU content. On the contrary, the tensile strength of the composites decreased with increasing PBAPU content. The scanning electron microscope images showed that the compatibility between the PLA matrix and PBAPU in the composites was improved significantly. Based on the analysis of the test results for the material's structure, morphology, thermal stability, fluidity, and other properties, it can be concluded that a bio‐based composite material with desirable performance was successfully prepared.

Published: May 2023

AbstractAlcoholysis is an important reaction for the current industrial production of ethylene‐vinyl alcohol (EVOH) copolymers. Herein, two series of ionic liquids (ILs), acidic and basic ones, were used as eco‐friendly catalysts for alcoholysis of ethylene‐vinyl acetate (EVA) copolymer. The effects of the reaction parameters (catalyst loading,n(CH3OH)/n(Ac) and reaction time), EVA composition, and nitrogen flow on the alcoholysis were systematically investigated. A nearly 100% of alcoholysis degree was achieved using acidic ILs ([BHSO3MIm][HSO4]) under the optimum conditions (3.0 mol% catalyst loading relative to the VA units in EVA,n(CH3OH)/n(Ac) = 30, 70°C, 6 h). Moreover, [BHSO3MIm][HSO4] could be reused at least five times without the decrease of catalytic activity, showing excellent recyclability. The interactions between IL and the substrate methanol and the model compound ethyl acetate were investigated by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance techniques, and on the basis of these results, the plausible mechanisms of acidic and basic ILs catalyzed alcoholysis of EVA were proposed.

Published: May 2023

AbstractThe effect of roll temperature from 60 to 120°C on the crystalline structure and properties of oriented polypropylene (PP) cast films and the stretched microporous membrane was studied. It was found that the long period, the thickness of the crystalline and amorphous phase increase with the increasing roll temperature. And the regularity of the lamellar structure also improves with the increasing roll temperature. In comparison, the lamellae lateral dimension is nearly unchanged at 50 nm. The orientation of the lamellar structure slightly decreases from 0.81 to 0.76 with increasing roll temperature. The increase of the long period and the improvement of the regularity of the lamellar structure lead to the increase of the elastic recovery value of PP cast film. The corresponding microporous membrane also shows a smaller thickness of lamellar clusters, larger pores, better air permeability and better thermal shrinkage resistance. The higher roll temperature is beneficial to the perfection of the lamellar structure, obtaining the higher‐performance microporous membrane.

AbstractThe synthetic feasibility and excellent luminescence features of organic molecules attracted much attention and were eventually found useful in lighting applications. In this context, a solvent‐free organic liquid having attractive thermally activated delayed fluorescence features in bulk along with high processability has prime importance. Herein, we report a series of naphthalene monoimide‐based solvent‐free organic liquids exhibiting cyan to red thermally activated delayed fluorescence with luminescence quantum yields up to 80% and lifetimes between 10 to 45 μs. An effective approach explored energy transfer between liquid donors with various emitters exhibiting tunable emission colors, including white. The high processability of liquid emitters improved the compatibility with polylactic acid and was used for developing multicolor emissive objects using 3D printing. Our demonstration of the thermally activated delayed fluorescence liquid will be much appreciated as a processable alternate emissive material suitable for large‐area lighting, display, and related applications.
Intergenerational transmission of educational disadvantage: Education progression of children of care leavers compared to a general population sample
Authors: Parsons Sam , Fitzsimons Emla , Schoon Ingrid 
Published: May 2023

AbstractThere is persistent evidence showing that care leavers tend to have lower educational outcomes compared to their peers. There is, however, less knowledge of whether this educational disadvantage transfers to the second generation. This study adopts a developmental contextual life‐course approach to examine: (a) the extent of educational inequality of children of care leavers from school entry to public examinations at age 16; (b) the relative role of different psychosocial family resources as predictors of educational attainment; and (c) the role of early school readiness assessments as predictors of later educational attainment. Drawing on data collected from families living in England at the first sweep of the nationally representative UK Millennium Cohort Study (MCS) (n = 11,514), the findings suggest intergenerational transmission of educational disadvantage among children of care leavers (n = 287), which is manifest in a direct assessment of school readiness (age 3), at the Early Years Foundation Stage (EYFS) (age 5) and in General Certificate of Secondary Education (GCSE) attainment (age 16). However, once inequalities in family socio‐economic background or area deprivation and housing are controlled for, children of care leavers perform comparably in their educational progression to those whose mothers had no experience of being in care (n = 11,227). Moreover, the findings highlight the significance of early school readiness assessments in predicting later educational attainment for the whole sample. Findings are discussed regarding their implications for policy, in particular the need to address educational inequality for children in care, area allocation and housing that is offered to care leavers, and the general importance of early interventions.
A note of feature screening via a rank‐based coefficient of correlation
Authors: Chen Li‐Pang 
Published: May 2023

AbstractFeature screening is a useful and popular tool to detect informative predictors for ultrahigh‐dimensional data before developing statistical analysis or constructing statistical models. While a large body of feature screening procedures has been developed, most methods are restricted to examine either continuous or discrete responses. Moreover, even though many model‐free feature screening methods have been proposed, additional assumptions are imposed in those methods to ensure their theoretical results. To address those difficulties and provide simple implementation, in this paper we extend the rank‐based coefficient of correlation to develop a feature screening procedure. We show that this new screening criterion is able to deal with continuous and binary responses. Theoretically, the sure screening property is established to justify the proposed method. Simulation studies demonstrate that the predictors with nonlinear and oscillatory trajectories are successfully retained regardless of the distribution of the response. Finally, the proposed method is implemented to analyze two microarray datasets.

AbstractSynthetic cells, expressing proteins using cell‐free transcription‐translation (TXTL), is a technology utilized for a variety of applications, such as investigating natural gene pathways, metabolic engineering, drug development or bioinformatics. For all these purposes, the ability to precisely control gene expression is essential. Various strategies to control gene expression in TXTL have been developed; however, further advancements on gene‐specific and straightforward regulation methods are still needed. Here, we present a method of control of gene expression in TXTL using a “silencing oligo”: a short oligonucleotide, designed with a particular secondary structure, that binds to the target messenger RNA. We demonstrated that silencing oligo inhibits protein expression in TXTL in a sequence‐dependent manner. We showed that silencing oligo activity is associated with RNase H activity in bacterial TXTL. To complete the gene expression control toolbox for synthetic cells, we also engineered a first transfection system. We demonstrated the transfection of various payloads, enabling the introduction of RNA and DNA of different lengths to synthetic cell liposomes. Finally, we combined the silencing oligo and the transfection technologies, demonstrating control of gene expression by transfecting silencing oligo into synthetic minimal cells.

AbstractBackgroundNoncommunicable diseases (NCDs) are the leading cause of morbidity and mortality worldwide. The aim of this study was to determine the prevalence of NCDs among the population of Cyprus and to identify the distribution of the socioeconomic and demographic determinants among individuals with the most frequent NCDs.MethodsA cross‐sectional study was conducted using stratified sampling. Socioeconomic and demographic characteristics and the presence of NCDs were collected through a standardized questionnaire. The diseases were classified using the 10th revision of the International Classification of Diseases (ICD‐10).ResultsIn total, 1140 individuals participated in the study, among whom 590 (51.7%) had at least one chronic disease. The most prevalent NCDs were hyperlipidemia (17.4%), hypertension (12.9%), and thyroid diseases (8.4%). We identified more males than females with hyperlipidemia aged 25–44 years old and >65 years old (p = 0.024), more males compared to females with hypertension (p = 0.001) and more females compared to males with thyroid diseases (p < 0.001). Individuals with hypertension and hyperlipidemia were more likely to be married, to have completed a higher education, and to have a high annual income.DiscussionIn Cyprus, the majority of the general population had at least one NCD. Hyperlipidemia, hypertension, and thyroid disease are relatively common, even at younger ages, highlighting the need for the development of public health programs aimed at addressing and preventing NCDs.

Published: May 2023

AbstractBenefiting from the features like polymeric linear structures, stimuli‐responsiveness and dynamic adaptiveness, supramolecular polymers (SPs) are favored as exploiting muscle‐like materials, allowing for imitating the muscle functions. However, a substantial part of these materials barely owned an unitary motion orientation while it was obviously known that muscle movements involved distinct orientations. Herein,M1holding the structure of 44‐membered macrocycle with two aldehyde groups was designed, meanwhile,M2comprising of secondary ammonium ions, 3,5‐di‐tert‐butylphenyl groups as well as the alkyl chains was fabricated, for which it could be assembled withM1to generate SPs based on host–guest interactions from a large macrocycle and two secondary ammonium ions. SPs underwent vertical compression upon the addition of N2H4owing to the forming dynamic covalent bonds, notably, mechanically interlocked structures were also generated. Afterwards, the vertically compressed SPs experienced horizontal shrinkage when tetrabutylammonium chloride was contributed due to the destruction of host–guest interactions.
Photocatalytic degradation of N‐nitrosodiethylamine from carbon capture plants using tungsten trioxide‐based catalysts: Parametric and optimization study

Published: May 2023

AbstractThis study reports the synthesis and characterization of tungsten trioxide‐based catalysts for the photocatalytic degradation of N‐nitrosodiethylamine (NDEA) in wastewater. Tungsten trioxide (WO3) was synthesized using the thermal treatment method (TTM) and hard template replication method (HTRM) and impregnated with lanthanum (La), iron (Fe), chromium (Cr), and silver (Ag) to enhance its light absorption ability. The synthesized catalysts were characterized using various techniques, including UV‐Vis spectroscopy, Brunauer–Emmett–Teller (BET), Barrett–Joyner surface area and porosity, X‐ray diffraction (XRD), and thermogravimetric analysis (TGA). The experimental design approach used a response surface methodology (RSM) with a face‐centered central composite design (FCCCD) technique. Catalyst loading (%), pH of solution, and catalyst concentration (g/L) were chosen as design factors, with the response variable being NDEA degradation efficiency (%). The obtained data were analyzed, and a quadratic model was chosen as the best fit with statistically significant model terms as observed from the analysis of variance (ANOVA). 3D interaction plots were generated to explain the effect of the various interaction terms of the quadratic model. The results showed that the pH of the solution was the major factor affecting NDEA degradation efficiency. The mean degradation efficiency of NDEA was 93.03% for Fe/WO3, 88.90% for Ag/WO3, 86.48% for La/WO3, and 84.03% for Cr/WO3. These findings demonstrate the potential of tungsten trioxide‐based catalysts impregnated with various metals for the effective treatment of NDEA in wastewater through heterogeneous photocatalysis.
