Published: August 2024

AbstractViologens are important members of organic photochromic (PC) materials. However, the photochromism of the viologen derivatives in solutions, especially in water, can be hardly detected due to the restricted photo‐induced electron transfer (PET) caused by the solvation of counter anions and fast rapid back electron transfer upon oxidation by the dissolved oxygen. Herein, a universal strategy is successfully developed for reversible photochromism of viologen derivatives in various solvents by simply adding an electron donor triethylamine (TEA). Upon the formation of a charge transfer complex, PET process can smoothly occur, resulting in the formation of stable viologen radicals. The PC kinetic analysis reveals that a viologen derivative with narrower bandgap exhibits faster coloration process upon ultraviolet (UV) light irradiation. Moreover, incorporating 1‰ eq. of a conjugation‐extended viologen derivative as a photosensitizer significantly shortens the coloring time of a conventional viologen without affecting its bleached and colored states. Based on the PC properties of viologen derivatives, distinct patterns are realized in their aqueous solutions and pre‐soaked erasable papers upon UV light irradiation. Overall, the findings not only develop a universal strategy for reversible photochromism of viologen derivatives in various solvents but also open a new avenue for information storage and anticounterfeiting applications.

AbstractTransition metal dichalcogenides (TMDCs) based large‐scalep‐type floating‐gate field‐effect transistor (FGFET) memory array has been fabricated for the first time. Chemical‐vapor‐deposition grown seamless co‐planes 2H‐ and 1T′‐MoTe2serve as the channel and source/drain electrodes, respectively. High‐κ Al2O3 layers act as the tunneling and blocking layers. Arrayed Pd/Au serves as floating and top gates. The overall performances of the devices are excellent among those of the reported TMDCs‐based FGFET memories. Typical device exhibits large memory windows of ≈11.5 and 2.8 V and on/off ratios of ≈104and 103in gate voltage sweep ranges of ±10 and ±5 V, respectively, with long retention time of more than 105s and good stress endurance of more than 5 × 104programming/erasing cycles. The conductance of the device can be precisely tuned by applying short potentiative and depressive ±5 V voltage pulses. The device yields are 100% and 93% under ±10 and ±5 V, respectively. The whole fabrication process is free from the transfer process and compatible with traditional silicon technology. This work paves the way for the application of TMDCs in large‐scale integrated circuits.

AbstractObjectivesHypertension is one of the major modifiable risk factors for cardiovascular mortality and morbidity throughout the world. Increased life expectancy leads to increase prevalence of non‐communicable diseases among the elderly people including Bangladesh. However, different studies reported high prevalence of uncontrolled hypertension ranging from 52.6% to 67.9% among the elderly people in different countries. With this view, we aimed to assess the frequency of uncontrolled blood pressure (BP) among the elderly hypertensive people and its associated risk factors and treatment pattern in Bangladesh.MethodologyThis cross‐sectional type of observational study recruited 246 eligible hypertensive elderly patients attending in 250 Bedded General Hospital, Jashore, Bangladesh dated from 1st July to 31st December 2022. A structured questionnaire was developed and data on associated risk factors, treatment pattern and current blood pressure (BP) measurement were collected by face‐to‐face interview for the purposive sampling technique.ResultsThe mean age of our study patients was 72 ± 7 years with a male and female ratio nearly 1:1. Of the total hypertensive patients aged over 65 years or more, 56.5% remained with uncontrolled hypertension even on their prescribed antihypertensive medications. The mean systolic (SBP) and diastolic (DBP) blood pressure were significantly high (P < 0.001) as 167 ± 22 mm Hg and 95 ± 11 mm Hg, respectively, among the uncontrolled hypertensive patients. However, we noticed the mean SBP and DBP among the total hypertensive patients were also significantly high (P < 0.001) as 148 ± 27 mm Hg and 87 ± 13 mm Hg, respectively. In this study, we reported that the mean number of last prescribed antihypertensive medications used by the total patients was 2 ± 1 (P =0.224) which was similar among the controlled and uncontrolled hypertensive patient groups. Among the elderly hypertensive patients, the most commonly prescribed antihypertensive medications were Amlodipine 39.8% (P =0.006), Olmesartan 29.3% (P = 0.186), Losartan 24.4% (P = 0.127), Bisoprolol 15.0% (P = 0.266) and Atenolol 14.6% (P = 0.224).ConclusionWe noticed high frequency of uncontrolled blood pressure among the elderly hypertensive patients, despite of using multiple antihypertensive medications in Jashore, Bangladesh.

AbstractINTRODUCTIONBlood‐derived microRNAs (miRNAs) are potential candidates for detecting and preventing subclinical cognitive dysfunction. However, replication of previous findings and identification of novel miRNAs associated with cognitive domains, including their relation to brain structure and the pathways they regulate, are still lacking.METHODSWe examined blood‐derived miRNAs and miRNA co‐expression clusters in relation to cognitive domains, structural magnetic resonance imaging measures, target gene expression, and genetic variants in 2869 participants of a population‐based cohort.RESULTSFive previously identified and 14 novel miRNAs were associated with cognitive domains. Eleven of these were also associated with cortical thickness and two with hippocampal volume. Multi‐omics analysis showed that certain identified miRNAs were genetically influenced and regulated genes in pathways like neurogenesis and synapse assembly.DISCUSSIONWe identified miRNAs associated with cognitive domains, brain regions, and neuronal processes affected by aging and neurodegeneration, making them promising candidate blood‐based biomarkers or therapeutic targets of subclinical cognitive dysfunction.Highlights

Published: August 2024

AbstractThis study, magnetic basic resin (MBR) was synthesized by radical polymerization and modification. Its functional groups, surface morphology, elemental composition, and magnetic value were determined by ATR‐FTIR FE‐ESEM, EDX, and VSM techniques. Subsequently, the usability of MBR as an adsorbent in the simultaneous adsorption of Tartrazine (Tart) and Reactive Blue‐4 (RB4) dye binary mixtures were examined. Maximum adsorption for both dyes, (170 mg/g for Tart and 184 mg/g for RB4), was observed under acidic conditions at a pH range of 1.5–2. It was determined that the adsorption of both dyes onto MBR occurred in a monolayer, and the saturation time was 90 min for Tart and 60 min for RB4. The adsorption of both dyes fitted the pseudo‐second‐order kinetic model. It was also concluded that intra‐particle diffusion was effective. Based on the thermodynamic parameters, it was concluded that the adsorption proceeded spontaneously and endothermically, additionally, the calculated E values led to the conclusion that electrostatic interactions dominated the adsorption of Tart and RB4. The MBR exhibited a notable affinity for Tart and RB4, even within a dense matrix containing both anions and cations. Furthermore, it maintained this high removal affinity across four consecutive uses, involving adsorption and desorption processes.

AbstractKaempferia subglobosa is a perennial medicinal plant in the Zingiberaceae family, identified as a new species in January 2024. To uncover the biological benefits of K. subglobosa and its compounds, investigation of the metabolites of the roots and rhizomes, yielded three new monoterpene‐chalcone conjugates, the globosones A–C, representing a rare metabolite group within the Zingiberaceae, along with six known compounds. The biogenetic pathway for the globosones involves an oxidative [3+2] cycloaddition between α‐phellandrene and 4’‐methoxy‐4,2’,6’‐trihydroxychalcone. Biological testing revealed potent xanthine oxidase (XO) inhibition by globosones A and B, with IC50 values of 7.0±1.0 and 3.0±0.2 μM, respectively, surpassing the positive control drug allopurinol (IC50 7.2±0.1 μM). Globosones A–C also showed good aromatase inhibition (IC50 3.0–3.5 μM). Molecular docking studies indicated that globosones A and B may inhibit xanthine oxidase through binding at the FAD domain site. The physicochemical properties of these isolates suggest that they possess characteristics suitable for additional biological assessment in more advanced test systems. This study enhances an understanding of monoterpene‐chalcone conjugate inhibitors of XO, and offers preliminary insights into the metabolites and bioactivities of K. subglobosa, uncovering potent biological activities associated with this newly discovered plant species.

Published: August 2024

AbstractThe sliding mode control has to design a sliding manifold for manipulating the system motion in engineering practice, making system asymptotic stability paramount. This is particularly challenging for using variable sliding manifold parameters to formulate the sliding manifold for fast convergence and precise control. While much of the research on sliding mode control has focused on constant sliding manifold parameters, comparatively little is known about the variable approach of the sliding manifold parameters. Therefore, sliding manifold parameters are treated as variables and are computed by a parameter tuning algorithm. Regarding the parameter tuning algorithm, its input is the sliding mode control law with variable sliding manifold parameters, and its output is the computed sliding manifold parameters that will be transmitted back to the sliding mode control law. Through tuning the sliding manifold parameters by an optimal method of lowest cost with the measuring value and model computing value of system states based on the historical information, the difference between the nominal model and the real system will be removed. Here we discuss a series of studies on the algorithm of tune sliding control that, collectively, develop an application of how the tune sliding controller steers the front wheels of the full self‐driving vehicle. The designed approach has been tested in a steering test vehicle to realize a good angle tracking performance of the electric motor steer‐by‐wire system.

Published: August 2024

AbstractFuel cell stack (FCS) is a practical power source for new energy vehicle applications, and fuel economy is a problem that many researchers are concerned about. In this paper, an adaptive real‐time control strategy aiming at improving fuel efficiency is proposed; the control purpose is to distribute the power requirement between the FCS and the battery to achieve good fuel economy. First, the FCS model is built according to experiment data, and in order to reflect the affection of the temperature to the proposed control strategy, the thermal model of the battery is established. Then the future power requirement is predicted via Bayes inference analysis. Based on the FCS model, the battery model, and the predicted power requirement, the real‐time control strategy is designed and solved with minimization principle optimization over the receding horizon. The proposed control strategy is validated both through simulation and hardware‐in‐loop (Hil) experiments on a 40 kW FCS. The results compared with the rule‐based (RB) strategy and the loss minimum strategy (LMS) show that the proposed control strategy can effectively reduce fuel consumption by 4%, and at the same time, it can help extend the life span of the battery by considering the temperature affection.
Berechnungsmodell zur thermischen Vorspannung nachträglich ergänzter Bewehrung
Authors: Schwarz Yannik , Sanio David , Mark Peter 
Published: August 2024

AbstractZentrale technische Einschränkung vieler Verstärkungsmaßnahmen ist, dass diese nicht für das Konstruktionseigengewicht wirksam sind. Zur Lösung wird für statisch bestimmte Tragwerke die gezielte Temperierung von in Schlitzen ergänzten Bewehrungsstäben vorgeschlagen. Ziel ist es, die Stäbe, die in ein Vergussmaterial eingebettet sind, thermisch vorzudehnen und somit an die Dehnung der Initialbewehrung anzugleichen. Die Verbundwirkung mit dem erhärteten Vergussmaterial verhindert nach dem Stoppen der Wärmezufuhr und dem damit verbundenen Abkühlen die Rückverformung der Stäbe. Dadurch entsteht eine Vorspannkraft, die dem Biegemoment aus dem Eigengewicht entgegenwirkt und die Zugzone des Bestandsquerschnitts entlastet. Im Beitrag wird ein analytisches Berechnungsmodell für das Verstärkungsverfahren vorgestellt und hergeleitet. Dieses wird anhand numerischer Berechnungen und in einer ersten experimentellen Umsetzung verifiziert. Die wesentlichen Einflussgrößen auf die Wirksamkeit der Verstärkung werden im Rahmen von Parameterstudien untersucht. Die Ergebnisse zeigen, dass die thermische Vorspannung von nachträglich ergänzten Bewehrungsstäben effektiv möglich ist und mit dem Berechnungsmodell die daraus resultierende Wirkung, je nach untersuchten Randbedingungen, mit einer Genauigkeit von 80 bis 97 % erfasst werden kann. Die Genauigkeit steigt mit zunehmender Querschnittshöhe, einer geringeren Ausgangstemperatur des Querschnitts sowie einer geringeren Wärmeleitfähigkeit des Betons im Initialquerschnitt.

AbstractThe conversion of solar‐thermal (ST) power into electrical power along with its efficient storage represents a crucial and effective approach to address the energy crisis. The thermoelectric (TE) generator can absorb ST power and transform it into electrical energy, making it a highly viable technology to achieve photo‐thermal conversion (PTC). However, the practical application of the pristine TE generator devices on a larger scale is still facing several challenges. On the one hand, the pristine TE generator device has low inherent PTC efficiency, thereby leading to low power conversion. On the other hand, such solar‐thermoelectric (STE) conversion does not provide the functionality of electric energy storage. Herein, an effective strategy has been proposed that employs a CoAl2O4 PTC coating to decorate the pristine TE generator for developing the STE generator device with the remarkable STE performance and then coupling this device with a supercapacitor (SC) for effective storage power. In comparison to the pristine TE generator, the developed STE device exhibited considerable enhancement in both the open‐circuit voltage (Voc) and its maximum power density, displaying more than a 4‐ and 15‐fold improvement, respectively. In addition, the feasibility of coupling this solar‐driven STE generator device in series with a SC for ST conversion and storage was verified, and the working mechanism has been elucidated. This work presents a promising approach to effectively convert and store clean solar power into electrical energy, enabling practical applications of STE generator devices in conjunction with other electrochemical energy storage devices.
Recent Advances in Artificial Anion Channels and Their Selectivity
Authors: Ren Bowen , Sun Yonghui , Xin Pengyang 
Published: August 2024

AbstractNature performs critical physiological functions using a series of structurally and functionally diverse membrane proteins embedded in cell membranes, in which native ion protein channels modify the electrical potential inside and outside the cell membrane through charged ion movements. Consequently, the cell responds to external stimuli, playing an essential role in various life activities, such as nerve excitation conduction, neurotransmitter release, muscle movement, and control of cell differentiation. Supramolecular artificial channels, which mimic native protein channels in structure and function, adopt unimolecular or self‐assembled structures, such as crown ethers, cyclodextrins, cucurbiturils, column arenes, cyclic peptide nanotubes, and metal‐organic artificial channels, in channel construction strategies. Owing to the various driving forces involved, artificial synthetic ion channels can be divided into artificial cation and anion channels in terms of ion selectivity. Cation selectivity usually originates from ion coordination, whereas anion selectivity is related to hydrogen bonding, ion pairing, and anion‐dipole interactions. Several studies have been conducted on artificial cation channels, and several reviews have summarized them in detail; however, the research on anions is still in the initial stages, and related reviews have rarely been reported. Hence, this article primarily focuses on the recent research on anion channels.

AbstractWe recommend best practices for the recovery of cobalt from LiCoO2 (LCO) lithium‐ion battery (LIB) cathodes by (i) leaching using green deep eutectic solvents (DES) and (ii) subsequent electrodeposition, through a case study of the choline chloride (ChCl):ethylene glycol (EG) DES. DES physical properties (conductivity, viscosity, and surface tension) were tailored by varying the composition between mole ratios of 1 : 2 and 1 : 5 (ChCl:EG). Examined along with leaching process parameters (temperature, duration), increasing the fraction of hydrogen bond donors (HBDs) decreased DES surface tension and enhanced leaching. Complete Co recovery was achieved using 1 : 5 ChCl:EG DES at 160 °C and 48 h. Leaching temperatures >160 °C are discouraged due to DES thermal degradation. The electrodeposition process was optimized for selective Co recovery with high faradaic efficiency. The leaching ability of the DES was antithetical to the stability of electrodeposition cell components and required operational parameter adjustment to minimize degradation. The optimized system (copper cathode and stainless‐steel anode) employing 1 : 5 DES leachate exhibited a faradaic efficiency of ~80 %, specific Co recovery of ~0.8 mg hr<M−1 cm−1 at 50 °C and evidence of uniform deposition. DES surface tension is a key descriptor of metal recovery, and guidelines are presented to maximize selective Co recovery.
