AbstractEthiopians have deep‐rooted traditions of using plants to treat ailments affecting humans and domesticated animals. Approximately 80% of the population continues to rely on traditional medicine, including for the prevention and treatment of viral diseases. Many antiviral plants are available to and widely used by communities in areas where access to conventional healthcare systems is limited. In some cases, pharmacological studies also confirm the potent antiviral properties of Ethiopian plants. Building on traditional knowledge of medicinal plants and testing their antiviral properties may help to expand options to address the global pandemic of COVID‐19 including its recently isolated virulent variants and prepare for similar outbreaks in the future. Here, we provide an ethnobotanical and pharmacological inventory of Ethiopian medicinal plants that might contribute to the prevention and treatment of viral diseases. We identified 387 species, about 6% of Ethiopia's known flora, for which records of use by local communities and traditional herbalists have been documented for the treatment of viral diseases. We provide a framework for further investigation and development of this vital resource much anticipated to help combat emergent viral diseases along with existing ones in Ethiopia and elsewhere.

Authors: Li Yuman , Lin Hong , Zhao Chang , Lam James 
Published: December 2023

AbstractThis paper studies the state estimation for cyber‐physical systems with multiple channels under joint Denial‐of‐Service and deception attacks. We show that the optimal estimator (OE) cannot be implemented in practice, as its computational complexity exponentially grows with respect to time. Then, we develop a centralized approximate optimal estimator (AOE) by using a generalized pseudo‐Bayesian algorithm. This AOE is not only computationally efficient, but also features theoretically guaranteed performance and stability. Specifically, it is proved when the attack success rate is less than a threshold value, both the OE and the AOE are stable, and the averaged performance deviation between the OE and the proposed AOE remains bounded. Finally, simulation examples are provided to illustrate the obtained results.
Hydrothermal Synthesis of Mg modified Nanobiochar from Spent Coffee Grounds for Effective Phosphate Removal: Kinetic and Isotherm Studies
Authors: Begna Sisaya Gemeda , Leul Mekonnen Menbere 
Published: December 2023

AbstractPhosphate removal/recovery is essential to maintain the quality of aquatic systems and ensure sustainable use of phosphorous. Herein Mg‐nano biochar (Mg/NBC) is prepared as an effective phosphate adsorbent through the valorization of spent coffee grounds into nanobiochar by hydrothermal acid digestion of its biochar resulting from a slow pyrolysis. Characterization of the adsorbent was done by SEM, FTIR, BET, and XRD. Mg/NBC showed a 12.84 % higher adsorption capacity than the unmodified nanobiochar. Adsorption studies confirmed that phosphate adsorption on Mg/NBC is favored in acidic conditions removing 95 % of the initial concentrations at pH 1. The Langmuir adsorption isotherm model is better fitted to the equilibrium data with a maximum adsorption capacity of 100 mg/g suggesting uniform monolayer adsorption. Phosphate adsorption on Mg/NBC was initially rapid and followed a pseudo‐second‐order kinetic with an equilibrium constant (K2) of 0.029 g/mg.min. Thermodynamic investigation at different temperatures revealed negative ΔG°, positive ΔH° and ΔS° values suggesting a spontaneous endothermic process involving the chemisorption of phosphate at the later stage of the adsorption. Further, the application of the prepared adsorbent in real wastewater resulted in 90 % phosphate removal suggesting the promising potential of the prepared adsorbent for practical use in phosphate removal/recovery.

AbstractIn the present work, we have investigated the 1,3‐cycloaddition reaction of isobutyraldehyde ((CH3)2CHCHO) with the simplest Criegee intermediate CH2OO using the OH laser‐induced fluorescence (LIF) method in a reaction tube. The experiments were conducted at temperatures and pressures ranging from 280 to 338 K and 5 to 150 Torr. We found that the bimolecular rate coefficient of the reaction is temperature‐ and pressure‐dependent. The measured rate coefficients at 100 Torr are (4.93±0.89), (4.46±0.80), (3.99±0.72), (3.56±0.64), (3.34±0.60), (2.98±0.54), (2.78±0.50)×10−12 cm3 molecule−1 s−1 at 280, 288, 298, 308, 318, 328, and 338 K, respectively. A high‐pressure limit rate coefficient of (4.47±0.80)×10−12 cm3 molecule−1 s−1 was obtained at 298 K by fitting the pressure‐dependent rate coefficients according to the Lindemann mechanism. The Arrhenius plot of the temperature‐dependent rate coefficients results in an activation energy of (−1.86±0.33) kcal mol−1 and a preexponential factor of (1.72±0.31)×10−13 cm3 molecule−1 s−1. In the atmosphere, the reaction of CH2OO with isobutyraldehyde may contribute to the sink of CH2OO in regions where isobutyraldehyde emission is intense under low temperature and low relative humidity conditions.

However, further requirement on the electrochemical performance is still a powerful motivator to improve battery technology. The solid electrolyte interphase (SEI) is considered as a key component on negative electrode, having been proven to be crucial for the performance, even in safety of batteries. Although numerous studies have focused on SEI in recent years, its specific properties, including structure and composition, remain largely unclear. Particularly, LiF, a common and important component in SEI, has sparked debates among researchers, resulting in divergent viewpoints. In this review, the recent research findings on SEI and delve into the characteristics of the LiF component is aim to consolidated. The cause of SEI formation and the evolution of SEI models is summarized. The distinctive properties of SEI generated on various negative electrodes is further discussed, the ongoing scholarly controversy surrounding the function of LiF within SEI, and the specific physicochemical properties about LiF and its synergistic effect in heterogeneous components. The objective is to facilitate better understanding of SEI and the role of the LiF component, ultimately contributing to the development of Li batteries with enhanced electrochemical performance and safety for battery communities.

AbstractHelicobacter pylori (H. pylori) infection presents increasing challenges to antibiotic therapies in limited penetration through gastric mucus, multi‐drug resistance (MDR), biofilm formation, and intestinal microflora dysbiosis. To address these problems, herein, a mucus‐penetrating phototherapeutic nanomedicine (RLs@T780TG) against MDR H. pylori infection is engineered. The RLs@T780TG is assembled with a near‐infrared photosensitizer T780T‐Gu and an anionic component rhamnolipids (RLs) for deep mucus penetration and light‐induced anti‐H. pylori performances. With optimized suitable size, hydrophilicity and weak negative surface, the RLs@T780TG can effectively penetrate through the gastric mucus layer and target the inflammatory site. Subsequently, under irradiation, the structure of RLs@T780TG is disrupted and facilitates the T780T‐Gu releasing to target the H. pylori surface and ablate multi‐drug resistant (MDR) H. pylori. In vivo, RLs@T780TG phototherapy exhibits impressive eradication against H. pylori. The gastric lesions are significantly alleviated and intestinal bacteria balance is less affected than antibiotic treatment. Summarily, this work provides a potential nanomedicine design to facilitate in vivo phototherapy in treatment of H. pylori infection.

Published: December 2023

AbstractExploiting pseudocapacitance in rationally engineered nanomaterials offers greater energy storage capacities at faster rates. The present research reports a high‐performance Molybdenum Oxynitride (MoON) nanostructured material deposited directly over stainless‐steel mesh (SSM) via reactive magnetron sputtering technique for flexible symmetric supercapacitor (FSSC) application. The MoON/SSM flexible electrode manifests remarkable Na+‐ion pseudocapacitive kinetics, delivering exceptional ≈881.83 F g−1 capacitance, thanks to the synergistically coupled interfaces and junctions between nanostructures of Mo2N, MoO2, and MoO3 co‐existing phases, resulting in enhanced specific surface area, increased electroactive sites, improved ionic and electronic conductivity. Employing 3D Bode plots, b‐value, and Dunn's analysis, a comprehensive insight into the charge‐storage mechanism has been presented, revealing the superiority of surface‐controlled capacitive and pseudocapacitive kinetics. Utilizing PVA‐Na2SO4 gel electrolyte, the assembled all‐solid‐state FSSC (MoON/SSM||MoON/SSM) exhibits impressive cell capacitance of 30.7 mF cm−2 (438.59 F g−1) at 0.125 mA cm−2. Moreover, the FSSC device outputs a superior energy density of 4.26 µWh cm−2 (60.92 Wh kg−1) and high power density of 2.5 mW cm−2 (35.71 kW kg−1). The device manifests remarkable flexibility and excellent electrochemical cyclability of ≈91.94% over 10,000 continuous charge–discharge cycles. These intriguing pseudocapacitive performances combined with lightweight, cost‐effective, industry‐feasible, and environmentally sustainable attributes make the present MoON‐based FSSC a potential candidate for energy‐storage applications in flexible electronics.

AbstractDeveloping well‐crystallized light‐absorbing layers remains a formidable challenge in the progression of kesterite Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. A critical aspect of optimizing CZTSSe lies in accurately governing the high‐temperature selenization reaction. This process is intricate and demanding, with underlying mechanisms requiring further comprehension. This study introduces a precursor microstructure‐guided hetero‐nucleation regulation strategy for high‐quality CZTSSe absorbers and well‐performing solar cells. The alcoholysis of 2‐methoxyethanol (MOE) and the generation of high gas‐producing micelles by adding hydrogen chloride (HCl) as a proton additive into the precursor solution are successfully suppressed. This tailored modification of solution components reduces the emission of volatiles during baking, yielding a compact and dense precursor microstructure. The reduced‐roughness surface nurtures the formation of larger CZTSSe nuclei, accelerating the ensuing Ostwald ripening process. Ultimately, CZTSSe absorbers with enhanced crystallinity and diminished defects are fabricated, attaining an impressive 14.01% active‐area power conversion efficiency. The findings elucidate the influence of precursor microstructure on the selenization reaction process, paving a route for fabricating high‐quality kesterite CZTSSe films and high‐efficiency solar cells.

Published: December 2023

AbstractNext‐generation batteries have long been considered a transition to more sustainable storage technologies. Among them, metal–air batteries (MABs) with low cost, high safety, and environmental friendliness have shown great potential for future large‐scale applications. Motivated by the desirable characteristics, significant progress is made in suppressing serious parasitic reactions, improving electrochemical performance, and increasing the energy density in MABs. Compared to the widely reported liquid electrolyte strategy, solid‐state electrolytes (SSEs) can thoroughly solve the volatilization challenges of liquid electrolytes and protect the oxygen electrodes without the formation of diffusion‐blocking oxide phases. Notably, SSEs for MABs are still in their infancy, and many thorny challenges still need to be solved. In this review, the main electrochemical mechanism, key challenges, and some important progress are sorted out for solid‐state MABs, such as lithium–air, zinc–air, aluminum–air, and magnesium–air batteries. Besides their fundamental significance, these configurations are further compared in terms of energy density, cost, carbon footprint, energy consumption, rate performance, cycle performance, safety, and air stability of prevailing electrolytes.

AbstractDefect engineering is recognized as an attractive method for modulating the electronic structure and physicochemical characteristics of carbon materials. Exploiting heteroatom‐doped porous carbon with copious active sites has attracted great attention for capacitive deionization (CDI). However, traditional methods often rely on the utilization of additional heteroatom sources and strong corrosive activators, suffering from low doping efficiency, insufficient doping level, and potential biotoxicity. Herein, hydrogen‐bonded organic frameworks (HOFs) are employed as precursors to synthesize N, O co‐doped porous carbon via a simple and green reverse defect engineering strategy, achieving controllable heavy doping of heteroatoms. The N, O co‐doping triggers significant pseudocapacitive contribution and the surface pore structure supports the formation of the electric double layer. Therefore, when HOF‐derived N, O co‐doped carbon is used as CDI electrodes, a superior salt adsorption capacity of 32.29 ± 1.42 mg g−1 and an outstanding maximum salt adsorption rate of 10.58 ± 0.46 mg g−1 min−1 at 1.6 V in 500 mg L−1 NaCl solution are achieved, which are comparable to those of state‐of‐the‐art carbonaceous electrodes. This work exemplifies the effectiveness of the reverse nitrogen‐heavy doping strategy on improving the carbon structure, shedding light on the further development of rational designed electrode materials for CDI.

Published: December 2023

AbstractDeveloping a facile strategy to activate the inert crystal face of an electrocatalyst is critical to full‐facet utilization, yet still challenging. Herein, the electrocatalytic activity of the inert crystal face is activated by quenching Co3O4 cubes and hexagonal plates with different crystal faces in Fe(NO3)3 solution, and the regulation mechanism of facet‐dependent quench‐engineering is further revealed. Compared to the Co3O4 cube with exposed {100} facet, the Co3O4 hexagonal plate with exposed {111} facet is more responsive to quenching, accompanied by a rougher surface, richer defect, and more Fe doping. Theoretical calculations indicate that the {111} facet has a more open structure with lower defect formation energy and Fe doping energy, ensuring its electronic and coordination structure is easier to optimize. Therefore, quench‐engineering largely increases the catalytic activity of {111) facet for oxygen evolution reaction by 13.2% (the overpotential at 10 mA cm−2 decreases from 380 to 330 mV), while {100} facet only increases by 7.6% (from 393 to 363 mV). The quenched Co3O4 hexagonal plate exhibits excellent electrocatalytic activity and stability in both zinc–air battery and water‐splitting. The work reveals the influence mechanism of crystal face on quench‐engineering and inspires the activation of the inert crystal face.

Published: December 2023

AbstractThe unique catalytic activities of high‐entropy alloys (HEAs) emerge from the complex interaction among different elements in a single‐phase solid solution. As a “green” nanofabrication technique, inert gas condensation (IGC) combined with laser source opens up a highly efficient avenue to develop HEA nanoparticles (NPs) for catalysis and energy storage. In this work, the novel N‐doped non‐noble HEA NPs are designed and successfully prepared by IGC. The N‐doping effects of HEA NPs on oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) are systematically investigated. The results show that N‐doping is conducive to improving the OER, but unfavorable for HER activity. The FeCoNiCrN NPs achieve an overpotential of 269.7 mV for OER at a current density of 10 mA cm−2 in 1.0 M KOH solution, which is among the best reported values for non‐noble HEA catalysts. The effects of the differences in electronegativity, ionization energy and electron affinity energy among mixed elements in N‐doped HEAs are discussed as inducing electron transfer efficiency. Combined with X‐ray photoelectron spectroscopy and the extended X‐ray absorption fine structure analysis, an element‐design strategy in N‐doped HEAs electrocatalysts is proposed to improve the intrinsic activity and ameliorate water splitting performance.

Published: December 2023

AbstractTwo‐dimensional (2D) materials are promising successors for silicon transistor channels in ultimately scaled devices, necessitating significant research efforts to study their behavior at nanoscopic length scales. Unfortunately, current research has limited itself to direct patterning approaches, which limit the achievable resolution to the diffraction limit and introduce unwanted defects into the 2D material. The potential of multi‐patterning to fabricate 2D materials features with unprecedented precision and low complexity at large scale is demonstrated here. By combining lithographic patterning of a mandrel and bottom‐up self‐expansion, this approach enables pattern resolution one order of magnitude below the lithographical resolution. In‐depth characterization of the self‐expansion double patterning (SEDP) process reveals the ability to manipulate the critical dimension with nanometer precision through a self‐limiting and temperature‐controlled oxidation process. These results indicate that the SEDP process can regain the quality and morphology of the 2D material, as shown by high‐resolution microscopy and optical spectroscopy. This approach is shown to open up new avenues for research into high‐performance, ultra‐scaled 2D materials devices for future electronics.

Published: December 2023

AbstractIndustry 4.0 changes traditional manufacturing relationships from isolated optimized cells to fully integrated data and product flows across borders with its technological pillars. However, the transition to Industry 4.0 is not a straightforward journey in which organizations need assistance. A well‐known approach that can be utilized during the early phases of the transition is to assess the capability of the organization. Maturity models are frequently used to improve capability. In this systematic literature review (SLR), we analyzed 22 maturity and readiness models based on 10 criteria: year, type, focus, structure, research methodology followed during the design of models, base frameworks, tool support, community support, objectivity, and extent of usage in practice. Our SLR provides a well‐defined comparison for organizations to choose and apply available models. This SLR showed that (1) there is no widely accepted maturity/readiness model for Industry 4.0, as well as no international standard; (2) only a few models have received positive feedback from the industry, whereas most do not provide any practical usage information; and (3) the objectivity of the assessment method is controversial in most of the models. We have also identified a number of issues as open research areas for assessing readiness and maturity models for Industry 4.0.
