Published: November 2024

AbstractStructural colors are widely used due to their eco‐friendliness, stability, and precise controllability. However, achieving dynamic structural colors typically requires complex fabrication processes and high‐quality material preparation. Here, a simple bilayer structure containing hydrogel micropattern and semi‐transparent ultrathin aluminum film is proposed that achieves the dynamic structural color with Janus effect. Combining experimental research and theoretical analysis, it is found that by merely controlling the electron‐beam exposure dose, the colors, and patterns with these hydrogel‐based Janus structures can be precisely and rationally designed. Additionally, the thickness and swellability of the hydrogel micropattern can be individually regulated, enabling imaging encryption/concealment with the optical Janus effect. The stability and cyclic performance of this structure are verified. The environmental sensitivity, real‐time adjustability, and stability of this hydrogel‐based Janus structural color make it suitable for applications such as secure information transmission and intelligent anti‐counterfeiting labels.
Prephase‐Based Reconfigurable Joint Amplitude‐Phase Control Metasurface for Multifunctional Scattering Manipulation

Published: November 2024

AbstractReconfigurable metasurfaces have gained significant attention due to their flexible capabilities in manipulating electromagnetic (EM) waves. In particular, amplitude and phase both play crucial roles in the wavefront regulation. However, most reported reconfigurable metasurfaces focus either on amplitude‐only or phase‐only control within a single polarization, thereby limiting their functionalities and applications. In this work, a design approach of dual‐polarization independently reconfigurable joint amplitude‐phase control metasurface is proposed. By increasing the bias voltage of the integrated p–i–n diode within the unit cell, the reflection magnitude can be continuously tuned from reflection to absorption and then switched back to reflection, allowing for a about 180° phase difference in the states. The nearly consistent and independent EM responses remain in the dual linear polarization. Furthermore, the geometric dimensions of the unit cell are adjusted to design two prephased unit cells with an approximately 90° phase difference, for enhancing the degree of freedom through metasurface array configuration. The scattering manipulation capabilities are demonstrated through full‐wave simulations and experiments, including polarization conversion, single‐beam and multi‐beam generation, modulation of scattering beam intensity, and more. The proposed metasurface can pave the way for new opportunities in scattering manipulation and enable advanced concepts for next‐generation multifunctional devices.

AbstractPbS quantum dots (QDs) are particularly promising in low‐cost short‐wave infrared (SWIR) photodetection and imaging applications. Herein, a novel method is introduced defined as the perovskite conversion method (PCM) fabricating PbS QDs by using perovskite nanocrystals (PeNCs) as the lead precursor. The elemental substitution mechanism for PbS QDs from PeNCs is proposed, and it is confirmed that PCM‐QDs are exhibiting a smaller trap density due to a natural perovskite passivated surface condition compared to QDs prepared via conventional hot injection method (HIM). Grazing‐incidence small‐angle X‐ray scattering (GISAXS) results indicate that a short‐range disorder of the QDs can lead to a long‐range disorder configuration in the inner structure of PCM‐QD superlattice, which leads to a compact configuration in the QD solid film facilitating charge carrier transport in devices. In a photoconductor‐typed SWIR photodetector (PD) comparison, PCM‐QD PDs exhibit a high responsivity of 468 A W−1 and detectivities of 2.1 × 1012 Jones, which are almost three times higher than the values in HIM‐QDs PDs. Moreover, PCM‐QD PDs further show a higher response speed and one magnitude order higher loss frequency than PCM‐QD PDs. PCM is promising in the fabrication of high‐quality QDs for advanced optoelectronic applications.
Nanocarriers Made of Natural Fatty Acids: Modulation of Their Release Profiles through Photo‐Crosslinking
Authors: Zhang Dong , Meng Yuxuan , Hao Min , Xia Younan 
Published: November 2024

AbstractNatural fatty acids are attractive carrier materials for drug delivery, but their rapid dissolution and degradation in vivo calls for new strategies to enhance their stability. Here we report a simple and versatile method capable of photo‐crosslinking carriers made of natural fatty acids for drug delivery under controlled release. By optimizing the crosslinking density, the nanoscale carriers show a high drug loading efficiency, together with a stable network structure for minimal degradation in a body fluid mimic. Fluorescence microscopy analysis also reveals the exceptional intracellular stability of the crosslinked network, resulting in negligible cytotoxicity toward A549 cells up to 24 h when loaded with a potent anticancer drug. We further extend this strategy to microscale carriers fabricated using electrospray. Upon photo‐crosslinking, the carriers show a retarded release of nerve growth factor, resulting in slower neurite outgrowth from dorsal root ganglion. This work holds promise for addressing the efficacy and safety issues critical to nanomedicine and related applications.

Published: November 2024

AbstractNano biosensors based on MXenes have been emerging as a promising tool in the detection of biomarkers, for the discrimination of diseases and in the detection of environmental pollutants. Their potential in sensing applications has also drawn a lot of attention to their unique qualities such as their high conductivity, huge surface area, outstanding hydrophilicity, biocompatibility, and simplicity of surface functionalization. The development of scalable synthesis techniques is essential to the large‐scale manufacturing and broad application of MXene‐based sensors. Furthermore, the stability of the MXene layers in diverse environmental circumstances continues to be a difficulty for their practical application. To increase the dependability and precision of MXene‐based sensors, their selectivity must be increased through functionalization and tuning. With innovative technologies like machine learning, MXene biosensor is now taken advantage of new opportunities. Personalized healthcare solutions, remote data analysis, and real‐time monitoring are all possible when MXene sensors and AI algorithms work together. Herein, the optical properties, synthesis approaches, role of MXene biosensors in machine learning, its significant challenges and future prospects of MXene‐based nano(bio)sensors are deliberated.

AbstractThe bidentate N, N, donor phenyl‐azo‐naphthaldoxime NpLH, 1 was used to synthesize the ruthenium(II) complex trans‐[Ru(NpL)(CO)Cl(PPh3)2], 2. It has been characterized by SCXRD, electrochemical and spectral studies. Computational analysis indicates that the low‐lying π*‐LUMO of the complex has substantial azo‐character of coordinated ligand. This property has been exploited to form an efficient electron transfer pre‐catalyst to effectuate dehydrogenative functionalization of a large number of benzyl alcohols to quinazolin‐4(3H)‐ones via condensation with diverse o‐amino benzamides as well as N‐substituted benzamides under aerobic conditions (57 entries). A reaction mechanism has been projected via isolation of intermediates and certain control experiments. Furthermore, it has been substantiated by theoretical scrutiny using density functional theory (DFT) calculation. The catalytic cycle involves stepwise hydrogen atom transfer (HAT) from benzyl alcohols to the Nazo atoms of the coordinated ligand with subsequent removal of the H‐atoms from the Nazo atoms to regenerate the active catalyst.

Published: November 2024

AbstractCoupling hydrogen evolution reaction (HER) with biomass valorization using a photoelectrochemical (PEC) system presents a promising approach for effectively converting solar energy to chemical energy. A crucial biomass valorization reaction is the production of value‐added 2,5‐furandicarboxylic acid (FDCA) via 5‐Hydroxymethylfurfural (HMF) oxidation reaction (HMFOR). To achieve efficient FDCA production, we demonstrate an effective photoanode strategy that combines metal silicidation, dopant segregation, and surface reconstruction to create a bimetallic silicide Ni0.95Pt0.05Si/n‐Si photoanode. The oxide‐free Ni0.95Pt0.05Si/n‐Si interface prepared by the metal‐silicidation process ensures efficient interfacial charge transport, while dopant segregation enhances the Schottky barrier height and photovoltage, and surface reconstruction dramatically improves the catalytic activity of the photoanode surface. The as‐prepared Ni0.95Pt0.05Si/n‐Si photoanode exhibited excellent PEC performance for HMFOR with high conversion of HMF (97.2 %) and yield of FDCA (80.3 %) under illumination. Furthermore, by integrating a surface reconstructed Ni0.95Pt0.05Si/n‐Si photoanode with a Ni0.95Pt0.05Si/p‐Si photocathode, a dual‐photoelectrode system was constructed capable of simultaneous production of FDCA and H2, which achieves high photocurrent density of 5 mA cm−2 at zero bias under illumination. This study offers an auspicious prospect for high cost‐effectiveness conversion from solar energy to industrial monomers.
Uses and Abuses of ‘Not Wanting Peace’ in the Context of the Israel/Palestine Conflict
Authors: Goodman Simon , Tiripelli Giuliana , Kambashi Ngosa 
Published: November 2024

ABSTRACTSince its inception, peace has eluded the modern state of Israel and while peace can be presented as an ideal aim, talk about peace has been shown to justify further conflict and harm in and beyond Israel and Palestine. The current analysis focuses specifically on online activity, where the aim of peace is shunned as it is deemed to be not wanted. A discursive analysis of interaction on the social media website Twitter (now X) shows that (1) opponents are presented as not wanting peace, often on the grounds that (2) Palestinians, or Muslims/Arab people more generally are too hateful to want peace, which means that Palestinians can be blamed for this lack of peace. Occasionally Israelis are also presented in this way. This argument (3) presents peace as something for Israel to offer and for Palestinians to accept or not, where they are deemed responsible if they do not accept terms that are presented to them. Together, these findings show that there is a move away from the interactional requirement to be in favour of peace, where not wanting peace can be used to support ongoing violence and conflict and, in this case, justify the status‐quo of ongoing violence and oppression of Palestinian people.

Published: November 2024

ABSTRACTThe current study was focused to assess the impact of geographical distribution (1325–3200 m, asl) on essential oils (EOs) yield, chemical composition, and biological activities of Juniperus communis leaves. Soil mineral content was also analyzed to understand its impact on chemical composition. EO yield variations were observed (0.22%–0.48%), with highest in J. communis collected from Thatri Dhaar (JCTH) (0.48%) sample. Further, refractive index, specific gravity, and optical rotation of EOs revealed notable differences among the samples. Six trace elements in soils were found, with iron being the most abundant at all locations. Total phenolic and flavonoid content indicated significant variations, with highest total phenolic content (TPC) in JCTH (6.100 ± 0.649 mg GAE/g) sample, whereas total flavonoid content (TFC) was in J. communis collected from Mooring (JCM) (1.126 ± 0.004 mgRE/g) sample. GC and GC/MS‐based metabolite profiling had shown overall thirty metabolites, including terpenes and monoterpene hydrocarbons. Free radical scavenging assays showed strong antioxidant activity of JCCI and JCTH samples (IC50‐ABTS = 4.222 ± 0.166 µg/mL and IC50‐DPPH = 3.211 ± 0.307 µg/mL, respectively). Moreover, EOs significantly inhibit α‐glucosidase and α‐amylase enzymes, Gram‐positive and Grnegative bacterial strains. These findings suggested its promising biological potential. Furthermore, identified metabolites‐based statistical analysis (principal component analysis [PCA] and hierarchical clustering analysis [HCA]) highlighted similarities and discriminations of geographically impacted samples. This research will be helpful to understand the metabolite composition and their accumulation under different environmental conditions.

Published: November 2024

ABSTRACTLichen sclerosus is a chronic, immune‐mediated dermatologic disorder primarily affecting the genital skin. Extragenital lichen sclerosus is rare, especially in men. We present a case of ELS in a 23‐year‐old male with lesions on the left upper extremity that had persisted for seven years. Over time, the lesions gradually spread to the left upper arm and scapular region. These lesions followed a band‐like distribution along Blaschko’s lines, without associated pruritus or pain. This unusual presentation posed a diagnostic challenge, highlighting the rarity of such manifestations.

Published: November 2024

ABSTRACTChromosomal trisomy syndrome is associated with diverse clinical phenotypes, including intellectual disability. Partial trisomy of the distal 17q is a rare anomaly with similar clinical features, including psychomotor and growth deficits, facial dysmorphism, and microcephaly. Here, we describe three patients from two unrelated families with terminal trisomy 17q. We performed G‐banding karyotype and chromosomal microarray analyses. The child in Family 1 had a 31.3 Mb mosaic duplication on chromosome 17. Family 2 comprised dizygotic twins with a 263 kb deletion on chromosome 15 and a 9.2 Mb duplication on chromosome 17; however, normal karyotyping results were obtained for both parents. We also analyzed the genetic mechanisms underlying the occurrence of these chromosomal aberrations and summarized the literature describing known genotype–phenotype correlations. Given the rarity of partial trisomy of terminal 17q, these cases will provide new insights into the diagnosis of this condition and genotype–phenotype correlations, which can aid in the detection of such conditions and genetic counseling.

Ni‐Catalyzed Stereodivergent Synthesis of N‐Glycosides
Authors: Chen Jinhong , Martin Ruben 
Published: November 2024

AbstractHerein, we describe a stereoselective Ni‐catalyzed N‐glycosylation of glycals. The reaction is enabled by addition of an in situ generated nickel hydride across an olefin prior to C−N bond‐formation. Stereodivergence can be accomplished on kinetic or thermodynamic grounds, thus giving access to either α‐ or β‐N‐glycosides with equal ease. The protocol is distinguished by its operational simplicity, generality and exquisite selectivity, thus offering a new gateway to expedite the synthesis of N‐glycosides.
How Perennials Survive the Droughts—Pulse–Reserve Dynamics in a Hyperarid Basin
Authors: Babad Avshalom , Bubenzer Olaf , Hecht Stefan , Groner Elli 
Published: November 2024

ABSTRACTThe hyperarid environment poses significant challenges to local vegetation. The main limiting factors are water scarcity and inconsistent precipitation regimes. Nevertheless, perennials flourish in hyperarid stream channels, predominantly acacia trees, which require significant amounts of water. This study seeks to reveal the mechanism that provides acacias with adequate water. Although the pulse–reserve model can explain how desert flora survives, hyperarid environments are much more complicated. Accordingly, direct rainfall is insufficient to sustain local perennials, which rely on runoff for their water source. The hyperarid Gvanim basin in southern Israel is a small watershed that supports many perennials, including a thriving population of acacia trees. High‐resolution hydrological monitoring, including rain, evaporation, soil water content and flash flood discharge, along with surveys of lithology and acacia populations, allowed us to calculate the water balance for the basin and quantify the components of the pulse‐reserve system. The results indicate that unique geological settings can retain runoff water from a single significant flash flood that is sufficient to sustain perennials even during drought years. We propose a modified pulse–reserve mechanism that provides water to large acacia trees during the hot dry summer in hyperarid areas.
Garnet as a Proxy for Deciphering Polymetamorphic Histories: An Example From the Sanandaj‐Sirjan Zone of Iran

Published: November 2024

ABSTRACTIn the central sector of the Sanandaj‐Sirjan zone of Iran, the Triassic‐to‐Jurassic ‘Hamedan Phyllites’ metamorphic complex shows a polymetamorphic evolution characterised by a main Barrovian‐ to Buchan‐type garnet+staurolite+kyanite/andalusite regional sequence, locally overprinted by a low‐pressure thermal event generated by vigorous Jurassic magmatic activity and the emplacement of voluminous composite plutonic complexes (e.g., Alvand). In this work, we explore the Hamedan phyllites enveloping the Jurassic Alvand granite batholith, particularly in the eastern sector at the transition from cordierite‐bearing hornfels to staurolite‐bearing schists. In this study, we present for the first time the textural characterisation and mineral chemistry of a previously undescribed minor population of post‐kinematic Mn‐rich garnet from the staurolite schists. We developed phase equilibria modelling to define the pressure‐temperature condition of its genesis. We then integrated the existing literature on metapelites from the study area to develop new thermobarometric models with those data to propose a revised evolution of the metapelites enveloping the Alvand batholith and the extent of its contact aureole. On a wider scale, this study provides evidence for the relevance of garnet, as chemical‐physical archive, in deciphering complex polymetamorphic histories where thermal events affect previously regional metamorphosed rocks under relatively hot gradients.
Beyond Labels: Unveiling the Interplay Between Identity and Name Changes in Firm Performance
Authors: Afrifa Godfred Adjapong , Amankwah‐Amoah Joseph 
Published: November 2024

ABSTRACTDespite the increasing prevalence of corporate name change (CNC) in tandem with a growing body of research on the subject, the boundary and contextual conditions under which CNC yield beneficial or detrimental effects remain underexplored in the current literature. Integrating organizational identity literature and the resource‐based perspective, we examine the boundary and contextual conditions under which name changes impact firm performance. Utilizing financial data from the Financial Analysis Made Easy (FAME) database and focusing on key variables (i.e., degree of internationalization (DOI), international geographical spread (IGS), firm size (FSIZE), country of destination (COD), and firm international or domestic status (STATUS)), we found that companies enjoy superior performance following CNCs. Additionally, the results show that DOI, IGS, and STATUS lead to lower performance after a CNC. However, FSIZE and COD have positive effects on the relationship between CNC and performance. We examine the key practical and theoretical implications.
