AbstractAn original way of elaborating vertical metal/molecules/metal memristive junctions through diazonium electrografting of the organic layer and inkjet‐printed top electrodes is reported here. The molecule of interest is a FeII coordination complex with ter‐pyridine ligands, having a diazonium anchoring group. The resulting junction exhibits a memristive behavior characterized by a high ON/OFF ratio and plasticity property. Through the application of advanced techniques such as UV–vis and Raman time‐resolved spectroelectrochemistry, the study demonstrates the significant role of switchable azo bonds derived from diazo electrografting in memristive behavior.
Recyclability‐by‐design of Printed Electronics by Low‐Temperature Sintering of Silver Microparticles
Authors: van Impelen David , González‐García Lola , Kraus Tobias 
Published: November 2024

AbstractA low‐temperature sintering mechanism of silver microparticles is established and used to enable the design‐for‐recycling of printed electronics. The formation of necks during the initial phase sintering of precipitated and atomized silver microparticles is studied. Temperature‐ and time‐dependent in‐situ analyses indicate the existence of a mobile silver species that provides efficient mass transport. The activation energy of neck formation identifies silver ion formation as the rate‐limiting step of low‐temperature silver sintering. It is demonstrated that resistivities of 271 times that of bulk silver can be attained after 40 minutes at 150°C. Low‐temperature sintering not only reduces the energy required during thermal treatment but it yields layers that are suitable for recycling, too. The resulting layers have conductive necks that are mechanically weak enough to be broken during recycling. Printed layers are redispersed and the recycled silver powder is reused without loss of the electrical performance in new prints. Their conductivities are industrially relevant, which makes this recyclability‐by‐design approach promising for manufacturing more sustainable printed electronics.

AbstractAimWe investigated whether autonomic nervous system resection during robotic rectal surgery contributes to urinary dysfunction and to what extent.MethodsThis retrospective cohort study included patients who underwent rectal surgery for primary rectal cancer between December 2011 and April 2021. We identified urinary dysfunction risk factors and examined the effect of autonomic nervous system resection extent on urinary dysfunction occurrence, with urinary dysfunction defined as a residual urine volume of >50 mL. Urinary dysfunction with no improvement over 1 y was defined as permanent urinary dysfunction.ResultsOf 1017 eligible patients, 78 (7.7%) required autonomic nervous system resection. Lateral lymph node dissection was performed in 357 patients (35.1%). Urinary dysfunction was observed in 102 patients (10.0%). We studied 32 (41.0%) of 78 patients who underwent autonomic nervous system resection and 82 (23.0%) of 357 patients who underwent lateral lymph node dissection presented with urinary dysfunction. Multivariate analysis revealed that lateral lymph node dissection and autonomic nervous system resection were significant predictors of urinary dysfunction. The urinary dysfunction incidence was notably higher in patients with autonomic nervous system unilateral total resection of at least one side than in those with bilateral preservation (65.4% vs. 28.8%, p < 0.01), and permanent urinary dysfunction exclusively occurred in these patients.ConclusionIn robotic surgery, autonomic nervous system resection and lateral lymph node dissection were independent risk factors for urinary dysfunction. Furthermore, the extent of autonomic nervous system resection may increase the risk of permanent urinary dysfunction.

Key points
Decreased overall dietary consumption of micronutrients may be linked to an increased risk of olfactory dysfunction (OD) including subjective report of OD, subjective report of phantosmia, and objective OD.
Interactions were identified between these micronutrients, suggesting that outcomes may vary depending on the mixture of micronutrients taken.
Impact of urinary culture on diagnosis and treatment strategy after empiric therapy in febrile neutropenic patients
Authors: Hata Natsumi , Ihara Takateru 
Published: November 2024

AbstractAimFebrile neutropenia (FN) is treated by a broad‐spectrum antimicrobial. Subsequent antimicrobial therapy depends on identifying the source of the infection. Although urinary tract infections (UTIs) are common and urine culture (UC) is a valuable diagnostic tool, uncertainties remain about the specific indications for conducting UC in FN. This study examined whether performing routine UC would affect the subsequent antimicrobial therapy in FN.MethodsAll emergency department patients who received chemotherapy for malignancy and met the definition of FN (neutrophil count <0.5 × 109/L and fever >37.5°C) were included. The patient's demographic data, clinical symptoms, urinalysis results, urine and blood culture results, antibiotic therapy and duration, and patient outcomes were extracted from electronic medical records. UC was defined as positive if >105 colony‐forming units/L were detected.ResultsIn total, 115 of the initial 124 cases were included in the analysis. Thirty‐one cases met the Infectious Diseases Society of America guideline definition for recommending UC (recommended group) and 84 cases did not (non‐recommended group). In the recommended group, 16 of 31 cases had a positive UC, and antibiotics were changed for nine, based on UC results. In the non‐recommended group, 15 of 84 cases had a positive UC, and antibiotics were changed for two. The same organism were identified in blood cultures. Seven of 115 cases were detected for the same pathogen in blood and urine cultures.ConclusionPerforming UC regardless of symptoms could diagnose several asymptomatic UTIs in FN, but seldom impact an antimicrobial treatment strategy.

ABSTRACTIn this study, Zeolitic Imidazolate Framework‐8 (ZIF‐8) nanomaterials were synthesized using a co‐precipitation one‐pot method that uses ethanol, methanol, and water as solvents for the precursors (2‐methylimidazole and Zinc nitrate hexahydrate), resulting in yields of 66.77%, 73.14%, and 68.12%, respectively. The as‐synthesized ZIF‐8 nanomaterials were thoroughly characterized by X‐ray diffraction analysis, transmission electron microscopy, ultraviolet–visible spectroscopy, and Fourier‐transform infrared spectroscopy. The X‐ray diffraction analysis showed that the crystallite size of ethanol‐based ZIF‐8 (24.76 ± 1.67 nm) was smaller than those synthesized in water (26.92 ± 1.89 nm) and methanol (31.39 ± 1.03 nm). However, methanol‐based ZIF‐8 exhibited lower crystallinity (85.93%) than water‐based ZIF‐8 (91.48%) and ethanol‐based ZIF‐8 (92.71%). Zeta potential studies revealed that ethanol‐based ZIF‐8 had a larger surface charge (+37 mV) than water‐based ZIF‐8 (+35 mV) or methanol‐based ZIF‐8 (+24 mV) |SPINPDF101. Transmission electron microscopy analysis confirmed particle sizes of 54.35 ± 2.11 nm for ethanol‐based ZIF‐8, 57.91 ± 2.26 nm for water‐based ZIF‐8, and 63.25 ± 4.12 nm for methanol‐based ZIF‐8. Thermogravimetric analysis indicated thermal stability up to 800 °C, with mass losses of 55.98% for ethanol‐ZIF‐8, 50.12% for water‐based ZIF‐8, and 65.36% for methanol‐based ZIF‐8 by 600 °C. In antibacterial studies, water‐based ZIF‐8 exhibited the largest zone of growth inhibition (17.30 ± 0.26 mm) against Escherichia coli compared to ethanol‐based ZIF‐8 (15.57 ± 0.32 mm) and methanol‐based ZIF‐8 (14.70 ± 0.20 mm). Pearson's correlation study revealed that zeta potential, crystallinity, and antibacterial activity are positively related. Furthermore, water‐based ZIF‐8, with a minimum inhibitory concentration of 50 μg/100 μL, confirmed evident cell membrane disruption. Molecular docking experiments revealed ZIF‐8's significant binding affinity for the E. coli protein 5AZC, supporting its robust antibacterial activity.
Reducible Drug Pyrazinamide as a Powerful Ligand to Assist Copper (II)‐Catalyzed N‐Arylation
Authors: Chai Mengliang , Wang Sha , Wu Fengtian 
Published: November 2024

ABSTRACTHerein, pyrazinamide (L1) was used as a powerful ligand to promote a CuSO4‐catalyzed reaction between aryl halides and imidazole (HID) under mild conditions, generating various N‐arylation products in good to excellent yields. The findings indicate that CuSO4 was reduced and coordinated with L1 to form [CuIL1], which activated ArX to produce [ArCuIL1X] through oxidative addition. This intermediate subsequently underwent reductive elimination to form N‐arylation products, with [ArCuILID] being generated from a reaction between [ArCuIL1X] and HID. This method was successfully extended to the synthesis of 2‐phenylindole and pyrrolo[1,2‐a]quinoxaline under mild conditions. The method significantly enhances the efficiency and cost effectiveness of C‐N coupling reaction.

ABSTRACTA simple, direct, and regioselective protocol to the synthesis of N1,N2‐bis(2,3‐diiodoaryl)benzene‐1,2‐diamines through highly regioselective microwave‐assisted/palladium‐catalyzed double C‐N arylations of 1,2,3‐triiodobenzene and benzene‐1,2‐diamine is reported. Remarkably, the C‐N arylations proceeded bimolecularly at the terminal positions, the most active and less hindered position. This process was efficient and tolerated a wide range of substrates. The reaction of electron‐rich/neutral 1,2,3‐triiodoarene systems and electron‐rich 1,2‐diamines under the optimized conditions provided the highest isolated yields. This article describes a method for the first and unprecedented synthesis of tetra‐iodinated N1,N2‐diarylbenzene‐1,2‐diamine and iodinated 5,10‐dihydrophenazine products that is regioselective and scalable and provides useful derivatives for other chemical reactions especially in the synthesis of new NHC ligands.

ABSTRACTThe study develops polyamine‐functionalized graphene oxide–supported NiCo2S4 nanomaterial using a metal–organic framework (MOF). This modification adds free amines and oxygen functionality to the graphene oxide electrode surface, resulting in the decrease in the 2 theta value from 11.2 to 7.1 and an increase in the interlayer spacing value from 1.4 to 7.8 nm. This modification enhances the surface properties, leading to improved wettability and dispersion stability. Additionally, bimetallic nanoparticles of NiCo2S4, synthesized via the ZIF‐67 MOF template, further enhance performance. Analysis confirms the successful fabrication of ZIF‐67/f‐GO/NiCo2S4 electrode material through various techniques such as XPS spectra, FE‐SEM, XRD, and Raman spectra. The resulting Salen‐fGO@NiCo2S4 composite exhibits impressive specific capacitance, reaching 2581.65 F g−1 at 10 A g−1 with 82% capacity retention after 5000 cycles. Employing this composite in a hybrid supercapacitor yields remarkable energy and power densities of 40 and 920 W kg−1, individually, while maintaining 74% capacity retention rate at 10 A g−1. These findings offer promising prospects for advanced energy storage applications.

Overcoming clay structure challenges in lithium recovery from boron waste using high‐temperature pressure acid leaching
Authors: Younes Noha Nagy , Turan Mehmet Deniz , Erdem Mehmet 
Published: November 2024

AbstractBoron mines contain significant amounts of lithium along with boron. After boron is extracted, lithium remains in the waste, which has a carbonate‐hosted clay‐type structure, along with other impurities. The scarcity of lithium resources and the increasing need for lithium worldwide make such resources economically important. Although the best hydrometallurgical method for the recovery of lithium trapped within the clay‐structured mineral resources is roasting with chemicals to disrupt the clay structure and acid leaching, the process is quite difficult and costly due to the high energy and chemical addition requirements. To overcome this challenge, this study proposed a high‐temperature–pressure sulphuric acid leaching process to recover lithium from the boron waste. Under the optimized conditions (liquid/solid ratio: 10, acid concentration: 1 M, temperature: 150°C, and contact time: 120 min), 100% of lithium was leached. The leaching mechanism was determined through mineral characterization (X‐ray diffractometry [XRD], X‐ray fluorescence spectrophotometer [XRF], scanning electron microscopy–energy‐dispersive X‐ray spectroscopy [SEM–EDX], Mastersizer), and a shrinking core heterogeneous kinetics model. It was found that high‐temperature–pressure sulphuric acid leaching disrupted clay structure and promoted the leaching of lithium, the leaching kinetics fit the shrinking core heterogeneous kinetics model, and was controlled by a dual mechanism with ash diffusion and chemical reactions on the particle surface. The reaction rate constants increased with increasing temperature, and the activation energy was found to be 32.17 kJ/mol.

Published: November 2024

ABSTRACTThe decline in biodiversity poses a serious threat to natural ecosystems and has become one of the most pressing global environmental issues. Establishing conservation priorities for protected areas (PAs) is one of the most direct and effective biodiversity conservation measures. However, conservation gaps arise as a result of existing problems in spatial layout of PAs, including overlapping protection scopes, artificial fragmentation of natural ecological regions, as well as “over‐protection” and “over‐exploitation.” To optimize the spatial layout of PAs and improve the efficiency of biodiversity conservation, we employed the Habitat Quality module of the Integrated Assessment of Ecosystem Services and Tradeoffs (InVEST) model and the Maximum Entropy (MaxEnt) model to assess the PAs in the Songnen Plain, China. The combined model (MaxEnt‐InVEST) revealed that the conservation priorities for PAs in the Songnen Plain occupied a total area of 14,764.14 km2 (10.24% of the total area of the Songnen Plain). The conservation priorities outside PAs occupied a total area of 7858.45 km2 (5.45% of the total area of the Songnen Plain) and were primarily distributed in the northeastern, central, and southwestern regions of the Songnen Plain. This indicated that existing PAs did not offer adequate protection for local biodiversity. The consistency of our combined modeling framework was 72.11%, which enabled a more accurate assessment of biodiversity hotspots and respects the land uses of the Songnen Plain. In addition, the modeling framework successfully created maps of conservation gaps of biodiversity hotspots based on actual species distribution data and considers current land uses. Our study was aimed at optimizing the spatial conservation efficiency of the Songnen Plain by assessing the conservation gaps in the Songnen Plain. It could provide a reference for the future development of a PA system centering on national parks.
Electrochemical Sensing/Biosensing ‐ Bench to Market
Authors: Janegitz Bruno 
Published: November 2024

The proposition of new sensors based on carbon (nano)structures as well as metal (nano)particles is a great alternative for electroanalysis. In this context, graphite, carbon nanotubes, graphene, carbon black and fullerene, as well as gold, silver, platinum, copper are the most common materials employed [1]. Also, biomolecules such as antibodies, DNA sequences, enzymes and aptamers can be promising molecular recognition elements and enable specific sensor/biosensor designs, with interferent species [2]. Since the pioneering works from Professor Joseph Wang [3,4], the screen‐printed and disposable electrodes have been reported in the literature as options to be used in point‐of‐care and point‐of use sites. Also, the evolution of 3D printing [5] and wearable devices have led to an increase in the number of papers reporting on their use.. The “Achilles heel” is that the laboratory creations don't make it to the market place [6]. Therefore, academia needs to think more about in the validation, demonstration and promotion of the laboratory developed technology with of new companies based on startups, for example, to attract investments and promote these sensors to commercial ones. In this context, the special issue “Electrochemical Sensing/Biosensing ‐ Bench to Market” brings the discussion and advances of electrochemical sensors, which can be used in many areas, such as medical, environmental, food safety, pharmaceutical, and forensic. For this purpose, the preparation, characterization, and application of these devices have attracted interest. Studies of the production, shelf‐life as well as reproducibility, and repeatability have been highlighted for mass production. Important subjects such as screen printing, and 3D printing are welcome for submissions. Therefore, we expect you to enjoy this Special Issue published in Electroanalysis. References [1] R. M.

Distributed photovoltaic reactive power control strategy based on improved multiobjective particle swarm algorithm
Authors: Liu Hongli , Li Hao , Li Ji , Shao Lei 
Published: November 2024

AbstractDistributed power supply access to the distribution network, although it can effectively support the band voltage, will also cause problems such as voltage overruns at the point of grid connection and large network losses, so this paper establishes a reactive power optimization model containing three objectives: network loss, voltage fluctuation rate, and static reactive power generator (SVG) installation capacity in distributed photovoltaic power generation scenarios by taking advantage of the characteristics of SVG that both absorb and send out reactive power. A multiobjective particle swarm algorithm with an adaptive grid and roulette mechanism is introduced to ensure the uniformity and diversity of the Pareto boundaries under the constraint that the output of each device does not exceed the constraints, and to obtain the optimal set of solutions capable of coping with the stochastic fluctuations of distributed power sources. When the algorithm is compared with three other algorithms, such as nondominated sorting genetic algorithm‐II, the results show that it reduces the network loss by about 25% and significantly improves the voltage fluctuation rate.
