Published: January 2023

AbstractThe functionality and use of wearable triboelectric nanogenerators (TENGs) are significantly impacted by the development of their tribomaterial properties. Herein, a novel charge‐generating layer (CGL) composed of a V2CTx/Silicone nanocomposite and serpentine TENG (S‐TENG) is introduced. The V2CTx/Silicone nanocomposite exhibits a highly electronegative surface, which significantly enhances the surface potential and charge density. The fabricated nanocomposite‐based TENG exhibits a peak power density of 19.75 W m−2. It also exhibits a high mechanical stretchability (400%), which is significantly better than those of previously reported TENGs under small external pressure. The optimized S‐TENG is demonstrated as a self‐powered human motion sensor with high sensitivity (4.93 V kPa−1) and a quick rise time (21 ms). Furthermore, a real‐life demonstration of sign language interpretation using finger motion detection and text conversion via smartphones is successfully performed. Additionally, the real‐time sensing ability of the S‐TENG is demonstrated in virtual reality car games controlled by finger touch. The S‐TENG is demonstrated to capture different types of human motion energy for continuously powering a stopwatch and wristwatch. Therefore, it is expected that the V2CTx/Silicone nanocomposite will continue with the contributions of novel CGL materials for various TENG applications including wearable self‐powered sensors, robotics, and healthcare monitoring in IoT platforms.

Published: January 2023

AbstractLithium‐ion/sodium‐ion batteries are the most advanced energy storage devices, but the structural evolution of electrode materials, electrolyte decomposition, the growth of Li/Na dendrites and the generation of heat and gas inside batteries represent serious safety issues. Therefore, it is necessary to real time monitor the parameter changes inside these devices. Herein, the recent important progress in a variety of advanced intelligent detection techniques based on the detection of heat, gas, and strain is introduced and discussed. The perfect combination of electrochemical parameters and these advanced intelligent sensing techniques allows the monitoring of the dynamic chemical and thermal evolution during a cell's operation without any impact, which is crucial to making meaningful advancements in energy storage devices. This work provide access to advanced diagnostic tools to guide the rational design of high‐safety batteries.
Three Component syn‐1,2‐Arylmethylation of Internal Alkynes**
Authors: Dutta Shubham , Sahoo Akhila K. 
Published: January 2023

AbstractA Pd‐catalyzed three‐component syn‐1,2‐arylmethylation of internal alkynes (ynamides/yne‐acetates/alkynes) is described. The readily available and bench stable coupling partners iodo‐arenes, and methyl boronic acid are successfully used in this coupling strategy to access the methyl‐containing tetra‐substituted olefins; the scope is broad showing excellent functional‐group tolerance. Notably, the transformation is regio‐ as well as stereoselective. The biologically relevant motifs (BRM) bearing iodo‐arenes and ynamides are also used for the late‐stage syn‐1,2‐arylmethylation of alkynes. Aryl‐alkylation, aryl‐trideuteriomethylation, alkynyl‐methylation, and alkenyl‐methylation of ynamides are also presented. The Me‐substituted alkenes are further transformed into synthetically important β‐amino‐indenones and α‐fluoro‐α′‐methyl ketones.

Published: January 2023

AbstractObtaining a robust and applicable enzyme for bioethanol production is a dream for biorefinery engineers. Herein, we describe a general method to evolve an all‐round and interpretable enzyme that can be directly employed in the bioethanol industry. By integrating the transferable protein evolution strategy InSiReP 2.0 (In Silico guided Recombination Process), enzymatic characterization for actual production, and computational molecular understanding, the model cellulase PvCel5A (endoglucanase II Cel5A from Penicillium verruculosum) was successfully evolved to overcome the remaining challenges of low ethanol and temperature tolerance, which primarily limited biomass transformation and bioethanol yield. Remarkably, application of the PvCel5A variants in both first‐ and second‐generation bioethanol production processes (i. Conventional corn ethanol fermentation combined with the in situ pretreatment process; ii. cellulosic ethanol fermentation process) resulted in a 5.7–10.1 % increase in the ethanol yield, which was unlikely to be achieved by other optimization techniques.

Published: January 2023

AbstractSince imidazole is easily protonated and well known to coordinated to various transition metals, its incorporation into a polymer with ferrocene may result in interesting electronic interactions between the ferrocenyl and imidazolium moieties. To this end, copolymers of vinylferrocene and vinylimidazole were prepared in various ratios by free radical polymerization. The interactions between the ferrocenyl and imidazolium moieties were studied by cyclic voltammetry, UV–Vis spectroscopy and density functional theory (DFT) studies. Cyclic voltammetry of polymer thin films showed multiple oxidation waves at low pH or in the presence of Pb2+ or Cd2+ ions. The UV–Vis spectrum of thin films showed an additional absorbance at 625 nm suggesting electronic interactions. In addition, DFT studies indicated that the morphology of the polymer would place some of the ferrocenyl and imidazolium moieties in close proximity.
Quasi‐periodic oscillations are more than timing features: Applying the accretion‐ejection instability in super massive black‐holes
Authors: Varniere Peggy 
Published: January 2023

AbstractLow frequency quasi‐periodic oscillations (LFQPOs) have always been seen uniquely as a timing feature, with most models focused on reproducing only their timing behavior. Previously, the accretion‐ejection instability (AEI) predicted the existence of a more subtle effect on their energy spectrum. In the case of low mass X‐ray binaries (LMXB), that effect was deemed impossible to detect. Although the AEI can be naturally expanded to higher‐mass systems, there was no observational drive to do it until now. However, the several (candidate) QPOs detected in supermassive black hole sources in the last decade, now seems the right moment to explore the applicability of the AEI model. Using our numerical observatory, we compute the different observables for a system with the AEI active and we take advantage of the longer timescale coming from the higher mass system, to see if the effect on the energy spectrum hinted at in LMXB, could become detectable. After confirming that the AEI causes an imprint of the QPO on the energy spectrum that should reach detectable levels in SMBH, we turned to observations of 2XMM J123103.2 and performed a proof of concept spectro‐timing fit of the QPO pulse profile simultaneously with how its energy spectrum changes along it. While the limited 2XMM J123103.2 data showed the predicted effect at only , it is fully consistent with the AEI model and hence worthy of further investigation in other systems.

AbstractBackgroundRidge regeneration for implant therapy requires comprehensive site evaluation and wound healing monitoring. This case report aimed to demonstrate ultrasound (US) can image soft and hard tissues for surgical planning and assess longitudinal outcomes.Methods and ResultsUS was used in a patient planned for ridge augmentation to evaluate soft tissue thickness, location of muscle attachment, and hard tissue defect features presurgically. US were obtained at 1, 2.5, and 5 months afterward to assess tissue healing. Preoperatively, US showed ∼2.5 mm and ∼0.8 mm soft tissue thickness on the facial and lingual sides, respectively. The crestal bone width was ∼2 mm, with severe facial bone deficiency and high muscle attachment. US showed wound approximation and ridge width gain to 4.5 and 4.0 mm at 1 and 5 months, respectively. US tissue perfusion increased to ∼two‐fold and ∼4‐fold at 1 and 2.5 months and reduced below the baseline at 5 months. An implant with simultaneous bone augmentation was performed accordingly. Tissue phenotype around the implant was measured on US images at 1‐year visit.ConclusionsThis case report demonstrated that US parameters could be valuable for planning and wound healing outcome assessment of ridge augmentation in clinical as well as research settings.Key pointsWhy is this case new information?

Simultaneous Hydrogen Bonds with Different Binding Modes: The Acceptor “Rules” but the Donor “Chooses”
Authors: Garcia Marianne Rica , Iribarren Iñigo , Rozas Isabel , Trujillo Cristina 
Published: January 2023

AbstractThis computational work studies the different hydrogen bond (HB) binding modes that can be established between neighbouring HB donors and acceptors in structures with relevance in catalysis and biology. To analyse the electronic effect on the σ‐hole, unsubstituted HB donors and ones with two different substituents, an electron withdrawing (EWG), and an electron donating (EDG) group, were studied. Upon complexation, three different binding modes were observed:bifurcated,parallel, andzigzag. It was found that, as a general trend, HBs within aparallelpattern are the strongest followed by those withinbifurcatedandzigzagbinding modes, leading to a “competition” between the last two. Similar patterns and trends have been found in experimental structures found in a search within the CSD. In conclusion, even though the HB acceptors “rule” the pattern and strength of the HB interactions within the dimers, when there is an option for different binding modes within a particular dimer, the HB donors “choose” the type of binding established.

AbstractMercury‐197 m/g are a promising pair of radioactive isomers for incorporation into a theranostic as they can be used as a diagnostic agent using SPECT imaging and a therapeutic via Meitner‐Auger electron emissions. However, the current absence of ligands able to stably coordinate 197m/gHg to a tumour‐targeting vector precludes their use in vivo. To address this, we report herein a series of sulfur‐rich chelators capable of incorporating 197m/gHg into a radiopharmaceutical. 1,4,7,10‐Tetrathia‐13‐azacyclopentadecane (NS4) and its derivatives, (2‐(1,4,7,10‐tetrathia‐13‐azacyclopentadecan‐13‐yl)acetic acid (NS4‐CA) and N‐benzyl‐2‐(1,4,7,10‐tetrathia‐13‐azacyclopentadecan‐13‐yl)acetamide (NS4‐BA), were designed, synthesized and analyzed for their ability to coordinate Hg2+ through a combination of theoretical (DFT) and experimental coordination chemistry studies (NMR and mass spectrometry) as well as 197m/gHg radiolabeling studies and in vitro stability assays. The development of stable ligands for 197m/gHg reported herein is extremely impactful as it would enable their use for in vivo imaging and therapy, leading to personalized treatments for cancer.
Recent advances in hydrogen production through catalytic steam reforming of ethanol: Advances in catalytic design
Authors: Rosha Pali , Ali Feysal M. , Ibrahim Hussameldin 
Published: January 2023

AbstractCatalytic reforming is a promising technology for producing renewable fuels; however, developing highly stable, efficient, green, and economical metallic catalysts that reduce metal sintering and carbon formation while improving catalyst activity, selectivity, and stability remains a major issue. In this regard, numerous studies have been documented in the past couple of decades evaluating the effects of various supports and promoters using ethanol as a co‐reactant in the catalytic steam reforming to produce energy‐efficient gaseous fuel, that is, hydrogen. This review article compiles research work focused on the catalytic reforming of ethanol reported in the last decade. Also, the outcomes of experimental studies have been presented and discussed for parametric analysis as case studies. The review shows that ethanol conversion, hydrogen selectivity, and catalyst stability are strongly influenced by the physicochemical properties of the catalyst, synthesis method, support choice, promoters, temperature, pressure, steam‐to‐ethanol ratio, and hourly space velocity. Noble metals (e.g., Pt, Rh, Ru, Pd, and Au), transition metals (e.g., Ni, Co, and Cu), and bimetallic composites were the most used catalysts in ethanol‐steam reforming reactions. Also, proper selection of support and promoter plays a significant role in modifying catalyst morphology, surface area, and particle size, enhancing selectivity, and reducing catalyst carbon deposition.
Optimization integrated generative adversarial network for occluded text recognition with language modeling
Authors: Selvaraj Selvin Ebenezer , Tripuraribhatla Raghuveera 
Published: January 2023

SummaryText recognition has attracted increased attention recently as a result of the complexity of natural settings and the variety of text instances. Various text or character recognition methods are introduced to distinguish the text from the natural scene, but existing methods struggle with the distorted and highly curved text instances. Consequently, an effective method for occluded text or character detection from object‐background images is developed using the suggested elephant herding exponential sailfish optimizer‐based generative adversarial network (EHESFO‐based GAN). In order to build the proposed EHESFO, elephant herding optimization and Exponential SailFish Optimizer (ESFO) are merged. ESFO was created by fusing exponentially weighted moving average and SailFish Optimizer. With GAN, features extracted from the background and foreground of an image are efficiently used for image annotation and text recognition. The best features from the background and foreground images are extracted to create the optimal solution, which increases the efficacy and efficiency of text recognition. While taking the occlusion as 0.4, the proposed EHESFO‐based GAN achieved higher accuracy of 98.1090% and lower error of 1.4%.
An integrated coupled inductor–capacitor DC–DC high step‐up converter
Authors: Afzal Raheel , Tang Yu , Tong Haisheng 
Published: January 2023

SummaryIn this paper, an integrated coupled inductor–capacitor DC–DC high step‐up converter is proposed for the renewable energy systems. A DC–DC high step‐up converter is mandatory owing to the comparative low output voltage of renewable energy systems. A new configuration has been proposed in this paper, in which capacitor and coupled inductor are integrated into a converter to achieve the required results. To charge the capacitor a coupled inductor is used, not only the voltage gain significantly boosted and the switch voltage clamped inherently but also the turns ratio and part count scale down. When proposed converter operates in ORF mode, this results in the decline of conduction losses and enhances its efficiency. The proposed converter has good efficiency and simplest structure as it has only six components. This paper illustrates the key state operation principles of the proposed converter and derivation of its steady‐state operations. A prototype is designed, and experiments are performed in the laboratory to verify the precision of the theoretical analysis. The highest efficiency of 97% has been achieved in the laboratory.
Dynamic structure factor and excitation spectrum of the one‐component plasma: The case of weak to moderate magnetization
Authors: Kählert Hanno , Bonitz Michael 
Published: January 2023

AbstractMagnetized plasmas are well known to exhibit a rich spectrum of collective modes. Here, we focus on the density modes in dense or cold plasmas, where strong coupling effects alter the mode spectrum known from traditional weakly coupled plasmas. In particular, we study the dynamic structure factor (DSF) of the magnetized one‐component plasma with molecular dynamics simulations. Extending our previous results (H. Kählert and M. Bonitz, Phys. Rev. Research 2022, 4, 013197), it is shown that Bernstein modes can be observed in the weakly magnetized regime, where they are found below the upper hybrid frequency, provided the coupling strength is sufficiently low. We investigate the DSF for a variety of different wave numbers and plasma parameters and show that even small magnetization can give rise to a strong zero‐frequency mode perpendicular to the magnetic field and change the dispersion as well as the damping of the upper hybrid mode.
Colour‐cuedparagraph writing instruction for students with learning disabilities

Published: January 2023

Expository paragraph writing is difficult to learn and teach. For many students, particularly those with learning disabilities, it is difficult to manage the multiple, simultaneous complex processes required for success. And for their teachers, writing is the content area in which they feel least prepared to teach. This intervention applied the concept of reverse engineering to instructional design to teach expository paragraph writing using a color‐cued graphic organizer. The study evaluated the effects of using a systematic color code to highlight the alignment of where ideas originate in a graphic organizer to their development into a sentence within a well‐organized expository paragraph. Using a single case research design, with a pre‐ and post‐intervention assessments, students (n = 5) with dyslexia improved their expository paragraph knowledge and skills. Percentage of non‐overlapping data and Tau analyses indicate a large to very large effect of the 2‐week intervention. Results, suggestions for further research, and implications for practice are discussed.

AbstractConversion of natural and secondary mixed forests to plantation monocultures can alter soil physical, chemical, and biological properties, which may lead to changes in ecosystem nitrogen (N) status by altering soil N availability. However, assessing and comparing N status between forest types within and across sites remain challenging because different indicators often yield contradicting conclusions. We developed a multiple‐indicator approach to evaluate N status across sites and between larch monocultures and mixed secondary forests paired at three sites (Daxinganling, Maoershan, and Qingyuan) in northeastern China. The selected indicators were foliar N content (%N), soil carbon‐to‐N ratio (C/N), soil inorganic N, foliar 15N natural abundance (δ15N), and δ15N of bulk soil, ammonium, and nitrate in the soil profiles. Our results, as shown mainly by C/N of soil organic layer and the fraction of nitrate in soil inorganic N, showed that N availability increased from north to south in the order Daxinganling < Maoershan < Qingyuan, along with the increasing climatic (mean annual temperature and mean annual precipitation) and N deposition gradients. We also found that the mixed forests had lower N availability than the larch plantations at the two north sites (Daxinganling and Maoershan), while the opposite was found in the south site (Qingyuan). The site‐specific pattern of N availability in the larch versus mixed stands reflects the difference in their succession and management histories. Our study demonstrated that a multiple‐indicator approach is needed for a comprehensive comparison of the N status of different forest types both within and across sites.

Published: January 2023

AbstractThe fatty acid (FA) composition of cell membranes represents a metabolic biomarker. However, the FA profile reproducibility in cell cultures remains a significant challenge. In this study, cell FA ratios are validated as metabolic markers alternative to cell FA. To this goal, cell samples belonging to cancer HeLa cells and normal 3T3 fibroblasts, from various experimental sets, are analyzed by a high‐performance liquid chromatography system coupled with a photodiode array detector and evaporative light scattering detector (HPLC‐DAD/ELSD), and the ratios among the main FA are calculated. Principal component analysis (PCA) separately performed on FA and FA ratio data indicates similar clustering of cell samples concerning the cell type. Moreover, similar scores values t[1] and t[2] and graphical distances are calculated in the PCA plots separately performed on FA and FA ratios measured in cancer HeLa cells subjected to various antitumoral compounds. Last, PCA applied to selected FA ratios measured in various cell lines, obtained in similar experimental conditions, allows to discriminate between normal and tumoral cells. The results substantiate FA ratios as a cell‐specific fingerprint, characterized by reproducibility across intra‐laboratory conditions, useful for cell characterization, discrimination between normal and tumoral cells, and the comparison of different drug treatments.Practical Applications: The reproducibility of the fatty acid (FA) profile in cell cultures remains a significant challenge. Results obtained from this study improve knowledge about the role of the FA ratio profile as a cell‐specific fingerprint characterized by reproducibility across intra‐laboratory conditions. The characterization of the specific FA ratio profile of a cell culture, under standardized experimental conditions, can facilitate the comparative evaluation of cell data sets for nutritional, metabolic, and pharmacological studies, overcoming differences in cell culture conditions and FA extraction/analytical procedures.
