AbstractConstructing uniform covalent organic framework (COF) film on substrates for electronic devices is highly desirable. Here, a simple and mild strategy is developed to prepare them by polymerization on a solid‐liquid interface. The universality of the method is confirmed by the successful preparation of five COF films with different microstructures. These films have large lateral size, controllable thickness, and high crystalline quality. And COF patterns can also be directly achieved on substrates via hydrophilic and hydrophobic interface engineering, which is in favor of preparing device array. For application studies, the PyTTA‐TPA (PyTTA: 4,4′,4′′,4′′′‐(1,3,6,8‐Tetrakis(4‐aminophenyl)pyrene and TPA: terephthalaldehyde) COF film has a high photoresponsivity of 59.79 μA W−1 at 420 nm for photoelectrochemical (PEC) detection. When employed as an active material for optoelectronic synaptic devices for the first attempt, it shows excellent light‐stimulated synaptic plasticity properties such as short‐term plasticity (STP), long‐term plasticity (LTP), and the conversion of STP to LTP, which can be used to simulate biological synaptic functions.

AbstractPhotodynamic therapy (PDT), as an emerging cancer treatment, requires the development of highly desirable photosensitizers (PSs) with integrated functional groups to achieve enhanced therapeutic efficacy. Coordination‐driven self‐assembly (CDSA) would provide an alternative approach for combining multiple PSs synergistically. Here, we demonstrate a simple yet powerful strategy of combining conventional chromophores (tetraphenylethylene, porphyrin, or Zn‐porphyrin) with pyridinium salt PSs together through condensation reactions, followed by CDSA to construct a series of novel metallo‐supramolecular PSs (S1–S3). The generation of reactive oxygen species (ROS) is dramatically enhanced by the direct combination of two different PSs, and further reinforced in the subsequent ensembles. Among all the ensembles, S2 with two porphyrin cores shows the highest ROS generation efficiency, specific interactions with lysosome, and strong emission for probing cells. Moreover, the cellular and living experiments confirm that S2 has excellent PDT efficacy, biocompatibility, and biosafety. As such, this study will enable the development of more efficient PSs with potential clinical applications.

AbstractTo reduce the economic loss caused by scale formation and corrosion of equipment and pipelines, a low phosphorus polymer scale inhibitor is synthesized and characterized, the ability of the polymer to mitigate the calcium scale and the influences of operating conditions on CaCO3 scale are investigated by static tests. X‐ray diffraction (XRD) and scanning electron microscope (SEM) studies are performed to understand the morphological changes of the scales in the presence of the polymer. The interaction between polymer molecules and calcite crystal surface is studied by molecular dynamics simulation. The synthesized polymer is compared with the commercial product such as hydrolysis polymaleic acid (HPMA), polyacrylic acid (PAA), and 1‐hydroxy ethylidene‐1,1‐diphosphonic acid (HEDP). The experimental results show that the polymer shows better inhibition of calcium scale than the commercial product. The scale inhibition efficiency of the polymer is 92% at 10 mg/L for CaCO3 scale, 83% at 14 mg/L for Ca3(PO4)2 scale, and 98% at 6 mg/L for CaSO4 scale. SEM and XRD analysis show that the polymer induces the conversion of CaCO3 from calcite to arachite and crystal. The interaction of the polymer with both 104 and 1–10 calcite crystal surfaces are more stable than that of commercial product. The experimental results are in good agreement with those of molecular dynamics simulation.

Published: January 2024

AbstractBiopolymer blend composite films based on polyvinyl alcohol (PVA) and chitosan (CS) incorporated with varying amounts of chicory extract (CE) have been developed by the green solution casting technique. The impact of CE content on structural, thermal, mechanical and electrical properties was thoroughly examined. The existence of intermolecular interactions in the blend composite was confirmed by Fourier‐transform infrared and ultraviolet spectroscopy. The x‐ray diffraction pattern proved the successful preparation of PVA/CS/CE composite film. The scanning electron microscopy images of the composites showed shape and grain size for the different bio‐filler contents. The thermal transition temperature of the blend composites was significantly improved by the addition of CE extract deduced from differential scanning calorimetry. The dielectric study showed that the permittivity remarkably increases with decreasing frequency and maximum dielectric constant was observed for 15 wt% loading. The activation energy obtained from the AC conductivity decreased as the temperature increased. The addition of CE extract improved the hardness and tensile strength of the PVA/CS blend composite in comparison with a pristine pure blend. The controllable mechanical, thermal, optical, and electrical characteristics of the PVA/CS blend composite suggest that it might be an attractive optical material for the advancement of futuristic flexible‐type optoelectronic and energy storage systems.

Abstract

North‐western Australia is considered a refuge to several highly threatened elasmobranch species, but there has been little research effort targeting lesser known, large‐bodied rhino rays. This study identified 2,343 records of globally threatened rays of the order Rhinopristiformes from the Pilbara region of Western Australia, with a focus on the Ningaloo Coast World Heritage Area and adjacent Exmouth Gulf.
Occurrence data were compiled from various sources including commercial fishing reports (35%), citizen science records (34%), targeted scientific surveys (30%) and published literature (1%). The region was inhabited by all of Australia's Pristidae (four sawfish species), all of Australia's Rhinidae (three wedgefish species) and the sole Australian representative of the Glaucostegidae (giant shovelnose ray). Of the 2,343 records, ~49% were sawfishes, while giant guitarfish and wedgefishes contributed to ~33% and 18% of records, respectively.
The Exmouth Gulf appears to be a globally important refuge and pupping area for green sawfish (Pristis zijsron) which was the most commonly encountered pristid. Bottlenose wedgefish (Rhynchobatus australiae) were the most commonly identified rhinid, with less frequent encounters of shark rays (Rhina ancylostoma) and eyebrow wedgefish (Rhynchobatus palpebratus). The Ningaloo Coast World Heritage Area and adjacent Exmouth Gulf host all life stages of giant shovelnose ray (Glaucostegus typus).
The combined use of several data sources has highlighted the study region as a ‘lifeboat’ for these globally threatened large‐bodied rays. These data are essential in creating effective conservation and management plans in this globally important refuge, and are highly relevant to global conservation initiatives.

AbstractGreen governance in heavily polluting industries is crucial for achieving sustainable economic growth. By analyzing Chinese A‐share listed companies from these industries between of 2010 and 2021, we assess the influence of multiple shareholding institutional investors (MSII) on a company's environmental performance. We find that MSIIs can improve environmental performance, highlighting their positive role in green governance. Further analyses reveal that this green influence stems from three key effects: supervisory oversight by principal shareholders, managerial incentives, and knowledge transfer. Consistent with the risk‐averse hypothesis, our study also suggests that MSIIs could drive the green transformation of heavy‐polluting industries out of risk aversion.

AbstractWearable electronics are expected to be light, durable, flexible, and comfortable. Many fibrous, planar, and tridimensional structures have been designed to realize flexible devices that can sustain geometrical deformations, such as bending, twisting, folding, and stretching normally under the premise of relatively good electrochemical performance and mechanical stability. As a flexible electrode for batteries or other devices, it possesses favorable mechanical strength and large specific capacity and preserves efficient ionic and electronic conductivity with a certain shape, structure, and function. To fulfill flexible energy‐storage devices, much effort has been devoted to the design of structures and materials with mechanical characteristics. This review attempts to critically review the state of the art with respect to materials of electrodes and electrolyte, the device structure, and the corresponding fabrication techniques as well as applications of the flexible energy storage devices. Finally, the limitations of materials and preparation methods, the functions, and the working conditions of devices in the future were discussed and presented.

Key Clinical MessageThis case report aims to raise awareness of differential diagnoses of hypercalcemia and primary hyperparathyroidism, including parathyroid carcinoma and atypical adenoma, and to highlight the diagnostic challenges.AbstractParathyroid carcinoma is a rare and often fatal cause of primary hyperparathyroidism and hypercalcemia. To date, there is still no clear‐cut diagnostic pathway for parathyroid carcinoma established, which results in major diagnostic ambiguity and complexity. Clinical differentiation between benign parathyroid adenoma and carcinoma is challenging and ultimately the diagnosis remains histopathological. We present a case of a 58‐year‐old female patient with parathyroid tumor recurrence after parathyroidectomy because of primary hyperparathyroidism. The first tumor was histologically classified as an atypical parathyroid adenoma by a specialized endocrine pathologist. Eleven years after the primary tumor resection a new tumor recurred. Retrospectively, after the tumor recurrence, the primary diagnosis of the atypical adenoma was questioned, and the tumor was temporarily classified to rather be a parathyroid carcinoma. This case aims to raise awareness for the diagnostic challenge of parathyroid carcinomas as a rare cause of primary hyperparathyroidism and therewith to improve treatment and prognosis.

Published: January 2024

AbstractMechanochemistry emerges as a promising and environment‐friendly method and has been widely applied in synthesis of solid catalysts. The catalyst with high surface area, uniform pore size, highly dispersed active metal and even single‐atom active metal can be synthesized by the mechanochemical approach. The mechanical agitation can give the catalyst unique properties, reflected in defect generation, structural arrangement and modified interaction, which is difficult to achieve by traditional synthesis methods. These unique structures of catalysts prepared by mechanochemical method lead to outstanding catalytic activity and excellent stability in the catalytic reaction. This review aims to summarize the recent advances in mechanochemical preparation of solid catalyst and application in catalytic reaction.

Published: January 2024

AbstractToward the construction of rechargeable batteries utilizing Zn metal has a high theoretical capacity, one of the solutions is to combine with the insertion/deinsertion of Na ions into/from hosts, but in the presence of two coexisting metal cations in dual‐salt electrolytes, it has been often left to spontaneity to determine which cations the host materials react with preferentially. The hybrid aqueous electrolytes containing 1 m Zn‐salt and 6 m Na‐salt were used, and the counter anions were TFSA− and Cl−, respectively. In the TFSA‐based electrolyte, the ligands for Zn ions and Na ions are water molecules to form positively‐charged hydrated cations. In contrast, for the Cl‐based electrolyte, Zn ions undergo partially solvation of Cl− to be stabilized as [ZnCl4(H2O)2]2− with negative charges while Na ions are predominantly hydrated. The galvanostatic discharge/charge tests, AC impedance measurements, and field‐emission electron probe micro analyzer revealed that in the Zn(TFSA)2/NaTFSA system, where both the cations are positively charged, Zn ions with higher charge density were inserted into the FePO4. On the other hand, in the ZnCl2/NaCl system, the FePO4 accommodated Na ions positively charged in the electrolyte solution rather than negatively charged Zn ions.

Published: January 2024

AbstractPorous aromatic framework 1 (PAF‐1) is an extremely representative nanoporous organic framework owing to its high stability and exceptionally high surface area. Currently, the synthesis of PAF‐1 is catalyzed by the Ni(COD)2/COD/bpy system, suffering from great instability and high cost. Herein, we developed an in situ reduction of the Ni(II) catalytic system to synthesize PAF‐1 in low cost and high yield. The active Ni(0) species produced from the NiCl2/bpy/NaI/Mg catalyst system can effectively catalyze homocoupling of tetrakis(4‐bromophenyl)methane at the room temperature to form PAF‐1 with high Brunauer–Emmett–Teller (BET)‐specific surface area up to 4948 m2 g−1 (Langmuir surface area, 6785 m2 g−1). The possible halogen exchange and dehalogenation coupling mechanisms for this new catalytic process in PAF's synthesis are discussed in detail. The efficiency and universality of this innovative catalyst system have also been demonstrated in other PAFs' synthesis. This work provides a cheap, facile, and efficient method for scalable synthesis of PAFs and explores their application for high‐pressure storage of Xe and Kr.

AbstractIndia is one of the leading producers of rice in the world. Gasification and pyrolysis are two thermochemical processes. In the gasification process, biomass is transformed into syngas, which serves as an energy source. This conversion occurs under high temperatures with a carefully regulated and restricted air supply. On the other hand, pyrolysis, which transpires at lower temperatures without the presence of air, generates pyrolysis oil as a by‐product. This oil can be further refined into liquid fuels. For the purpose of investigating the feasibility of biofuel production, the current study involved the characterization of rice straw biomass using various techniques such as thermogravimetry differential thermal analysis (TG/DTA), Fourier transform infrared (FTIR), carbon, hydrogen, nitrogen, sulphur and oxygen (CHNS/O), inductively coupled plasma optical emission spectroscopy (ICP‐OES), among others. These analytical methods were employed to assess the potential of rice straw biomass for the production of biofuels. The existence of a significant amount of cellulose (32.1%), volatiles (approximately 67.06%), and high heating value (HHV) (13.18 MJKg−1) in rice straw inferred their capability to be used as feedstocks in the production of biofuel. The activation energy of approximately 173.20 KJ/Mol (Flynn Wall Ozawa [FWO]) indicated the viability of the burning process. From master plot (Z(α)) analysis, the experimental curve was seen passing through different theoretical curves, indicating the complex nature of the pyrolysis process for rice straw.
A drought and heat risk assessment framework for urban green infrastructure
Authors: Shehayeb Raghid , Ortlepp Regine , Schanze Jochen 
Published: January 2024

AbstractUrban green infrastructure (UGI) is a prominent concept toward climate adaptation and urban resilience, but it is also affected by droughts and heat. Hence, this study aims to advance the multi‐assessment of drought and heat risks (DHRs) for UGI through the DHR assessment framework with conceptual and methodological features, paving the way toward knowledge creation and decision support. The framework was systematically developed, starting with defining the situation, analyzing concepts, and finally, constructing the framework. The situation is interpreted as a coupled human and natural system to represent the biophysical and immaterial elements, processes, and interrelations. Further, the concepts of risk, UGI, and ecosystem services lead to a risk system showing the compound hazards, the exposure, and the cascading vulnerabilities of the UGI. The DHR assessment framework distinguishes two stages, multi‐risk analysis and multi‐criteria risk evaluation. The analysis includes the definition and interpretation of the UGI situation under drought and heat conditions, analyzing the hazards, exposures, and vulnerabilities of the system, and translating the risk system into an indicator‐based information system. Hereby, the vulnerability analysis of the biophysical UGI aspects comprises the susceptibility and resilience of UGI entities, as well as the degree to which providing ecosystem functions and services can be affected. The multi‐criteria risk evaluation covers the assignment of thresholds and weights for indicators, in addition to the aggregation methods. The resulting framework intends to support local actors in the risk assessment of current and future conditions, fostering evidence‐based decisions and interventions to deal with compound DHRs.

Published: January 2024

AbstractMicroplastics (MPs) have recently attracted a lot of attention worldwide due to their abundance and potentially harmful effects on the environment and on human health. One of the factors of concern is their ability to adsorb and disperse other harmful organic pollutants in the environment. To properly assess the adsorption capacity of MP for organic pollutants in different environments, it is pivotal to understand the mechanisms of their interactions in detail at the atomic level. In this work, we studied interactions between polyethylene terephthalate (PET) MP and small organic pollutants containing different functional groups within the framework of density functional theory (DFT). Our computational outcomes show that organic pollutants mainly bind to the surface of a PET model via weak non‐bonding interactions, mostly hydrogen bonds. The binding strength between pollutant molecules and PET particles strongly depends on the adsorption site while we have found that the particle size is of lesser importance. Specifically, carboxylic sites are able to form strong hydrogen bonds with pollutants containing hydrogen bond donor or acceptor groups. On the other hand, it is found that in such kind of systems π‐π interactions play a minor role in adsorption on PET particles.
Revisiting the Chemistry and Photophysics of 3‐(N‐Methylpyridinium‐4‐yl)Coumarins for Designing “Covalent‐Assembly” and “Molecular Disassembly” Fluorescent Probes**

AbstractThe constant need for high‐performance aniline‐ or phenol‐based fluorophores suitable for the construction of activity‐based fluorescent probes, led us to study both synthesis and photophysics of C3‐N‐methylpyridinium‐4‐yl substituted 7‐(dialkylamino)/7‐hydroxycoumarins. Indeed, in the field of photoactive organic molecules, the positively charged N‐alkylpyridinium‐4‐yl groups are often used as acceptor units to dramatically impact spectral features through promoting intramolecular charge transfer (ICT) processes. They are also known as effective water‐solubilizing and mitochondria targeting moieties. The poor fluorescence efficiency of cationic 7‐hydroxycoumarin derivatives in aqueous physiological conditions was highlighted and rationalized by the predominance of a neutral quinonoid form in such buffer medium. The ability of the excited singlet state (S1) of this neutral species to undergo intersystem crossing (ISC) to triplet state (T1) was partly supported by phosphorescence measurements of singlet oxygen. We also took advantage of green‐emissive properties of 7‐(diethylamino)‐3‐(N‐methylpyridinium‐4‐yl)coumarin to successfully design and validate a novel small‐molecule fluorescent probe for the detection of alkaline phosphatase (ALP), based on the “covalent‐assembly” principle. A practical use of ortho‐formylated 7‐hydroxy‐3‐(N‐methylpyridinium‐4‐yl)coumarin was next considered with the synthesis of a Fe(III)‐salen complex whose the potential as a “molecular disassembly” probe for fluorogenic sensing of pyrophosphate (PPi) anion was assessed.
