AbstractWith the rapid development of 5G networks, the Internet of Things, and new‐generation of AI, there are considerable demands on expanding the capacity of contemporary optical fiber communication systems. One of the most effective avenues involves the extension of the bandwidth of Er‐doped fiber amplifiers, but with limited success. Herein, an Er‐activated hybridized glass fiber are reported, which can help realize broadband telecommunication. The effect of element hybridization on the bandwidth of Er‐activated fiber is clarified and the structure‐optical response relationship is established. A two‐step deposition approach is proposed to overcome the immiscibility barrier of different hybridized elements, and Er‐activated fiber with uniform doping is constructed. The activated fiber presents excellent compatibility with commercial telecommunication systems, providing a small signal gain of >13 dB in the whole L‐band range and a maximum gain of 28 dB. Furthermore, the Er‐activated fiber amplifier device is successfully developed. It exhibits outstanding optical amplification performance with gain >24 dB in the range of 1580–1624 nm, gain fluctuation less than ±0.9 dB, and noise figure <6.5 dB. The results not only provide a new strategy for developing novel active broadband optical fibers, but a valuable solution for new‐generation large‐capacity optical fiber communication systems.
Harnessing mesenchymal aggregation for engineered organ‐level regeneration: Recent progress and perspective
Authors: Zheng Chen‐Xi , Sui Bing‐Dong , Jin Yan 
Published: December 2023

AbstractStem cells, especially mesenchymal progenitors or mesenchymal stem cells (MSCs), possess an intrinsic property to form compact spheroid‐like assemblies, a phenomenon known as cell aggregation. In recent years, a growing body of researches have uncovered that this is a cross‐species conserved developmental event essential for initiating organogenesis in a variety of organs. Moreover, the self‐assembly property also contributes to the regenerative capacities of MSC aggregates in vivo with broad range of applications in tissue engineering. In this review, the principles of self‐assembled mesenchymal aggregation and its involvement in physiological organogenesis, as well as the construction approaches of engineering MSC aggregates and its application for organ regeneration are discussed. The authors aim to provide a speculative overview of the current understanding and the recent findings of cell aggregation, from both the developmental and the engineering perspectives, and thus offer insights into the understanding of stem cell biology and the establishment of novel organ regeneration strategies.

AbstractIn this paper, uniformly transition metal oxide (MoO3) nanosheets were electrochemically deposited on flexible carbon cloth (CC), and then conductive polyaniline (PANI) was orderly wrapped around their surface by electrochemical polymerization. The morphology and structure of as‐obtained self‐supported PANI/MoO3/CC electrode were investigated by FTIR, X‐ray diffraction, Raman, scanning electron microscope (SEM), transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy measurements in detail. Among all PANI/MoO3/CC electrode, the self‐supported PMC‐3 (deposition time of 300 s) has high specific capacitance of 841.6 F g−1 at current density of 0.5 A g−1 in the three‐electrode system, having specific capacitance of 595.7 F g−1 even at 10 A g−1. Novelty, the as‐assembled symmetrical capacitor is flexible and convenient with power density of 199.93 W kg−1 at the energy density of 9.69 Wh kg−1 and the energy density of 3.88 Wh kg−1 at power density of 4000 W kg−1. Thus, the electrochemical properties of the self‐supported PANI/MoO3/CC electrode were significantly improved, and the self‐supported electrodes are more competitive than other materials in practical application of clean energy storage systems.

Published: December 2023

AbstractCable accessory has the interface formed by cross‐linked polyethylene (XLPE)/silicone rubber (SiR), which is prone to surface discharge and thus causes the failure of cable system. This article conducts the simulated experiment of thermal–mechanical aging on the interface of XLPE/SiR. The interfacial breakdown and dielectric properties under different aging states are analyzed. It is found the interfacial aging process of XLPE can be divided into the recrystallization stage and the oxidation reaction stage. The former contributes to the interfacial roughness and thus the better insulating performance, whereas the latter leads to degradation of interface, and thus the worse insulating performance. In addition, combined with the established electric field model for the interface, the differences between thermal–mechanical aging and individual thermal aging on the interface are discussed. The sample under thermal–mechanical aging reaches the maximum interfacial breakdown voltage later than that under individual thermal aging, but their performance tends to be consistent in the later stage of aging.

Published: December 2023

AbstractAromatic trithia p‐benzihexaphyrins and nonaromatic doubly fused trithia p‐benzihexaphyrins were synthesized in a one pot reaction by condensing a p‐benzithiophene based tetrapyrrane with three different bithiophene diols under acid catalyzed conditions. The aromatic and nonaromatic macrocycles showed clear differences in colour, NMR, absorption, and electrochemical properties. Theoretical studies supported the observed aromatic and nonaromatic characteristics, respectively, of the p‐benzihexaphyrins and their N‐fused derivatives.

Published: December 2023

AbstractCupressus torulosa is an evergreen tree with a wide distribution in north‐western Himalayan region of India. Its needles have long been used in traditional medicine for anti‐inflammatory, antimicrobial, and wound‐healing properties. This study aimed to scientifically validate the traditional claim of the needles to treat inflammation by evaluating the chemical composition, antioxidant potential, and anti‐inflammatory activity of the essential oil extracted from the needles (CTEO) using hydro‐distillation. Qualitative and quantitative chemical composition of the CTEO was determined with the aid of GC‐MS and GC‐FID techniques. The major constituents of the CTEO were terpinen‐4‐ol (393.8±12.5 μg/mg), totarol (55.0±17.2 μg/mg), and sabinene (43.7±2.8 μg/mg). CTEO exhibited significant antioxidant activity when evaluated using DPPH free radical scavenging and reducing power assays. Furthermore, the CTEO demonstrated good anti‐inflammatory behavior in in vitro egg albumin denaturation assay, with an IC50 of 27.32 μg/mL. In vivo tests using carrageenan‐induced paw edema and xylene‐induced ear edema in rats showed significant effects at doses of 30 mg/kg for up to 1 hour. The significant discoveries not only support the established assertions about the anti‐inflammatory properties of C. torulosa needles but also highlight their potential as a useful resource in the growing herbal, complementary, and alternative medicine sectors.

AbstractThis study presents a novel approach to synthesizing silver nanoparticles (Ag NPs) using a solution combustion synthesis (SCS) method with Catharanthus roseus (C. roseus) leaf extract. The NPs were thoroughly characterized through X‐ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X‐ray (EDX), Transmission electron microscopy (TEM), and Selected area electron diffraction (SAED), elucidating their crystal structure. Notably, the synthesized Ag NPs exhibited a significant dose‐dependent decline in viability of the MDA‐MB 231 breast cancer cell line, with an IC50 value of 13.3 μg/mL, underscoring their potential as potent anticancer agent. Beyond cytotoxicity, the study pioneers an investigation into the biocompatibility of Ag NPs by blood hemolsysis, providing critical insights into their safety and biomedical applicability. Furthermore, this research uncovers a distinctive facet of Ag NPs, revealing their inhibitory effects on the inflammatory enzyme secretory phospholipase A2 (sPLA2), a recognized biomarker for breast cancer. The demonstrated in vitro and in vivo inhibition of sPLA2 highlights the multifaceted potential of Ag NPs in not only targeting cancer cells but also modulating inflammatory responses associated with breast cancer, positioning the study at the forefront of advancements in nanomedicine and cancer therapeutics.

Authors: Deng Ziwei , Sun Zhiyi , Li Yaqiong , Pei Jiajing , Chen Wenxing 
Published: December 2023

Comprehensive SummaryEnergy transformation is imminent, and hydrogen energy is one of the important new energy sources. One of the keys to increasing the rate of hydrogen evolution during electrolysis is the use of high‐performance catalysts for oxygen evolution reactions (OER). Single‐atom alloys (SAAs) have garnered significant attention because they partially reduce costs and combine the advantages of both single‐atom catalysts (SACs) and alloy catalysts. Herein, an efficient pyrolysis strategy based on a mixing and drying process is designed to anchor ultra‐small Co cluster particles, combined with Ru single atoms dispersed on nitrogen‐doped ultra‐thin carbon nanosheets (Ru1Co SAA/NC). The prepared electrocatalyst exhibits superior OER activity and superb stability, demonstrating an overpotential of 238 mV for OER with a current density of 10 mA·cm–2 in 0.5 mol/L H2SO4. And we also utilized in‐situ XAS to detect the oxidation state of Ru sites during OER. All in all, this method achieves cost reductions and efficiency improvements through the design of SAAs, offering new prospects for the structural transformation of clean energy.
Secured tracing for group signatures from attribute‐based encryption
Authors: Perera Maharage Nisansala Sevwandi , Matsunaka Takashi , Yokoyama Hiroyuki , Sakurai Kouichi 
Published: December 2023

SummaryThis article presents a tracing mechanism for group signatures answering the security threats of malicious authorities and users' forgeries. The proposal weakens the high trust placed on the centralized tracing party in previous group signatures by decentralizing tracing power using a multiple tracer setting and limiting the tracers' access using attribute‐based encryption and the requirement of the group manager's agreement. We allow the group manager to control tracers identifying his group users. Instead of a centralized tracer, our setting has multiple tracers possessing attribute sets. Thus, after getting the group manager's permission, a tracer should satisfy the access policy in a given signature to identify the signer. On the other hand, our group signature scheme decentralizes the tracing key generation and removes the group manager's tracing ability. Thus, it ensures that only the attribute‐satisfying and permitted tracers can identify the signer. Moreover, this article delivers security against malicious users. It presents a verification process of access policy of the signatures to prevent users from utilizing invalid attributes for signing. In addition, the article delivers a collaborative tracing mechanism to satisfy attribute sets that a tracer fails to fulfill alone for identifying a signer. Thus, our tracing mechanism ensures security against malicious authorities and group users in group signatures. The article gives the general construction of the scheme and discusses the security.
Integrating Enhanced‐Efficiency Fertilizers in 4R Nutrient Management
Authors: Nigon Leanna Leverich 
Published: December 2023

AbstractThe 4R nutrient stewardship framework has brought us closer to improving our nutrient use efficiency. However, given the inherent “leakiness” of the N cycle, it is challenging to increase N use efficiency to optimum levels. Newer fertilizer technologies, like enhanced‐efficiency fertilizers (EEFs), are tools that can help achieve this goal. To determine if EEFs should be incorporated into nutrient management programs, growers and crop advisers should consider the various types of EEFs available, their functions within the soil, and the timing of application relative to the crop’s nutrient uptake demand.

Published: December 2023

AbstractBone tissue has the capacity to regenerate under healthy conditions, but complex cases like critically sized defects hinder natural bone regeneration, necessitating surgery, and use of a grafting material for rehabilitation. The field of bone tissue engineering (BTE) has pioneered ways to address such issues utilizing different biomaterials to create a platform for cell migration and tissue formation, leading to improved bone reconstruction. One such approach involves 3D‐printed patient‐specific scaffolds designed to aid in regeneration of boney defects. This study aimed to develop and characterize 3D printed scaffolds composed of type I collagen augmented with β‐tricalcium phosphate (COL/β‐TCP). A custom‐built direct inkjet write (DIW) printer was used to fabricate β‐TCP, COL, and COL/β‐TCP scaffolds using synthesized colloidal gels. After chemical crosslinking, the scaffolds were lyophilized and subjected to several characterization techniques, including light microscopy, scanning electron microscopy, and x‐ray diffraction to evaluate morphological and chemical properties. In vitro evaluation was performed using human osteoprogenitor cells to assess cytotoxicity and proliferative capacity of the different scaffold types. Characterization results confirmed the presence of β‐TCP in the 3D printed COL/β‐TCP scaffolds, which exhibited crystals that were attributed to β‐TCP due to the presence of calcium and phosphorus, detected through energy dispersive x‐ray spectroscopy. In vitro studies showed that the COL/β‐TCP scaffolds yielded more favorable results in terms of cell viability and proliferation compared to β‐TCP and COL scaffolds. The novel COL/β‐TCP scaffold constructs hold promise for improving BTE applications and may offer a superior environment for bone regeneration compared with conventional COL and β‐TCP scaffolds.
Predicting the activity of methoxyphenol derivatives antioxidants: II—Importance of the nature of the solvent on the mechanism, a DFT study
Authors: Khelifi Roumaissa , Latelli Nadjia , Charifi Zoulikha , Morell Christophe , Chermette Henry 
Published: December 2023

AbstractThe various mechanisms of primary antioxidant action of a series of 2‐Methoxyphenols are investigated in the present work. The electronic properties have just been studied in a joint article, so that we focus here on Hydrogen Atom Transfer (HAT), Single Electron Transfer–Proton Transfer (SET–PT) and Sequential Proton‐Loss Electron‐Transfer (SPLET) mechanisms. The two computational approaches used in the previous study of the structure and reactivity of these compounds [Computational and Theoretical Chemistry 1229 (2023) 114287] provide identical mechanisms trends in gas phase. In gas media, hydrogen atom transfer (HAT) is more favored. On the contrary, the solvent polarity has a significant effect on the mechanism of the antioxidant activity, since the polarity of the solvent increases the contribution of the SPLET mechanism.
Multi‐institutional retrospective review of acute generalized exanthematous pustulosis (AGEP) induced by hydroxychloroquine
Authors: Bang Alexander S. , Blank Nina R. , Fox Lindy , Ko Justin , Worswick Scott , Harp Joanna 
Published: December 2023

AbstractBackgroundAcute generalized exanthematous pustulosis (AGEP) is a rare and severe cutaneous drug eruption. Hydroxychloroquine (HCQ) is one of the known culprit drugs with less than 60 cases reported in the literature, and may have a more severe clinical presentation compared to AGEP induced by other drugs. There are no standardized management strategies for HCQ‐induced AGEP outside of drug discontinuation.ObjectivesCharacterize the clinical presentation of HCQ‐induced AGEP and management strategies.MethodsRetrospective chart review of nine patients clinically diagnosed with HCQ‐induced AGEP using the EuroSCAR score from 2017 to 2022 at four academic medical centres in the United States.ResultsAll patients in our series were female and the median age was 52. Four patients initially presented with fever, and eight patients had neutrophilia. Median time to rash was 15 days. Biopsies obtained in six patients showed typical characteristics of AGEP. In most patients, rash morphology consisted of generalized pinpoint pustules atop atypical targetoid lesions and annular plaques. Five patients were hospitalized for AGEP. All patients were treated with methylprednisolone and/or prednisone, and the average days treated with systemic corticosteroids was 35.ConclusionsOur case series is the largest to date describing HCQ‐induced AGEP. Clinicians should be wary that HCQ‐induced AGEP may present with a longer latency period after drug initiation and with atypical targetoid and annular lesions. Early initiation of systemic corticosteroids should be considered due to the severity of this drug reaction with addition of cyclosporine in refractory cases.
Electronic structure of 1,3‐diphenyl‐2‐azaallenyl radical cation
Authors: Yim Daniel , Kim Young‐Kwan , Park Ji Hun , Kim Hyungjun 
Published: December 2023

AbstractQuantum chemical simulations were conducted to elucidate the electronic structure of the 2‐azaallenyl radical cation, a key intermediate in several [3 + 2]‐cycloadditions initiated by the oxidation of 2H‐azirine. We propose one additional Lewis structure in resonance with the commonly accepted two Lewis structures for the model system of 1,3‐diphenyl‐2‐azaallenyl radical cation, drawn from comprehensive theoretical data including molecular shape, bond order analysis, partial atomic charges, and spin densities. In addition to the ground state chemistry, the chemical structure of excited state species can be also understood with these three Lewis structures. Theoretical data imply that a newly suggested one mainly accounts for the ground state structure, and the excited state structure is better represented by the previously reported ones. Our claim is further bolstered by the prediction of the excited state geometries of the dicationic and neutral species. This research presents the extended set of Lewis structures for a better understanding electronic structure of 2‐azaallenyl radical cation.

SummaryInformation on appointments to the Fungal Nomenclature Bureau is provided. Appointments to two Special‐purpose Committees are reported. The following four generic names are recommended for conservation: Bilimbia with a conserved type; Coccotrema against Lepolichen; Fuscidea against Maronea; and Leptogium (lichenized Ascomycota) with a conserved type. The following two generic names are not recommended for conservation: Marcelaria against Buscalionia; and Variolaria Pers. against Lepra and Variolaria Bull. The following seven species names are recommended for conservation: Lecidea parmeliarum (Abrothallus parmeliarum) against Endocarpon parasiticum; Lichen cervinus (Acarospora cervina) with a conserved type; L. ferrugineus (Blastenia ferruginea) with a conserved type; L. flavus Bellardi (Pleopsidium flavum) against L. flavus Schreb.; Megaspora verrucosa (Ach.) Arcadia & A. Nordin against M. verrucosa Hafellner & V. Wirth.; Umbilicaria spodochroa with a conserved type and with that spelling; and Usnea fulvoreagens with a conserved type. The following three species names are not recommended for conservation: Alectoria fuscescens (Bryoria fuscescens), nom. cons., against the additional names Usnea implexa, A. capillaris, A. cana, A. rubens, A. fuscidula, A. degenii, A. forissii, A. ostrobotniae, A. kuemmerleana, A. haynaldiae, A. achariana, A. lanestris, A. prostratosteola, and A. viridescens; Lichen fuscovirens (Collema fuscovirens) against L. pulcher; and Ochrolechia szatalaensis against Pertusaria poriniza. The following two species names are recommended for rejection under Art. 56: Lecidea cornea and Lichen conspurcatus. The following generic name is recommended for rejection under Art. 56: Huea (and the original proposal to conserve Huea with a conserved type is not recommended). It is recommended that the species name Variolaria torta not be rejected under Art. 56. The proposal to conserve Pertusariaceae against Variolariaceae is considered unnecessary because the latter name is illegitimate. The Nomenclature Committee for Fungi could not arrive at a recommendation on the proposal to conserve Lagerheimia (De Toni) Chodat against Lagerheima Sacc. and nor resolve requests for binding decisions on whether the pair Geisleria Nitschke and Geissleria Lange‐Bert. & Metzeltin and the pair Lagerheima Sacc. and Lagerheimia (De Toni) Chodat are sufficiently alike to be confused – but these three items have now been resolved by the General Committee.
