Aims: To carried out performance analysis of a shunt active power filter (SAPF) for harmonics mitigation.
Study Design: Experimental design through simulation studies using P-Q Theory and proportional integral controller.
Place and Duration of Study: Department of Physics, Nasarawa State University Keffi, main campus, Nigeria, between October 2020 and September 2021.
Methodology: Primary and secondary data were obtained using AVO Digital Multimeter and manufacturers’ datasheets from Schneider electric website to capture required system parameters, SAPF was designed using a Voltage Source Inverter model to represent the Three-Phase source, and P-Q Theory with PI Control was used for reference current extraction. The SAPF was modeled, designed and simulated using MATLAB-Simulink and analyzed under different nonlinear load conditions and harmonic spectrum to achieve low Total Harmonic Distortion (THD).
Results: The THD in the unbalanced system voltages before the application of SAPF was found to be 12.6%, 11.4% and 11.2%, while after the application of SAPF was 2.2%, 2.5% and 2.5% for phase voltages a, b and c respectively. The grid currents indicated THD of 27.2%, 30.9% and 31% before application of SAPF and 2.2%, 2.2% and 2.1% after application.
Conclusion: The use of non-linear loads; has adverse effects on the quality of electric power as well as phase voltage and frequency waveforms. The use of SAPF is of vital importance in improving electric power quality for reliable power supply and quality service delivery.

ObjectiveThe optimal management of patients with incidentally found clinically isolated aortitis (CIA) after aneurysm repair is unclear. This study compared long‐term surgical and clinical outcomes after surgical repair of thoracic aortic aneurysm between patients with CIA and patients with noninflammatory etiologies.MethodsThis is a matched cohort study. Patients with CIA were identified by histopathology following open thoracic aortic aneurysm repair. Two comparators without inflammation on pathology were matched to each patient by year of surgical repair. Outcomes included surgical complications, new vascular abnormalities on imaging, and death.ResultsOne hundred sixty‐two patients were included: 53 with CIA and 109 matched comparators. Median follow‐up time was similar between groups (CIA 3.7 vs. comparator 3.3 years, P = 0.64). There was no difference in postoperative complications, surgical revision, or death between groups. Only 32% of patients with CIA saw a rheumatologist in the outpatient setting and 33% received immunosuppressive treatment. On surveillance imaging, no difference was seen in new or worsening aortic aneurysms, but there were significantly more vascular abnormalities in branch arteries of the thoracic aorta in patients with CIA (39% vs. 11%, P < 0.01).ConclusionAmong patients who underwent surgical repair of a thoracic aortic aneurysm, patients with CIA were more likely than noninflammatory comparators to develop radiographic abnormalities in aortic branch arteries. Notably, there was no difference in risk of new aortic aneurysms or surgical complications despite most patients with CIA never receiving immunosuppression. This suggests that more selective initiation of immunosuppression in CIA may be considered after aortic aneurysm repair.

Published: October 2022

AbstractTo enhance the energy density of batteries and explore intrinsic charge storage mechanism of the active materials, it is important to reduce or eliminate the use of non‐active materials in electrodes, such as binder and conductive additives. Herein, free‐standing Na4MnV(PO4)3@C (F‐NMVP@C) fiber membrane is fabricated and directly used as a sodium‐ion battery (SIB) cathode. In situ X‐ray diffraction reveals that the V3+/V4+ redox reaction occurs through a solid‐solution reaction while a two‐phase Mn2+/Mn3+ redox reaction is identified, and both are highly reversible. Meanwhile, ex situ electrochemical impedance spectroscopy reveals that both the ion diffusion coefficient and charge transfer resistance of F‐NMVP@C change reversibly during the Na+ intercalation/de‐intercalation. Battery full cells are assembled based on the free‐standing F‐NMVP@C cathodes and F‐Sb@C anodes, which manifests a high energy density (293 Wh kg−1) and good cyclability (87.5% after 100 cycles at 1 C). The high‐performance free‐standing cathodes and anodes shed light on the development of flexible SIBs.

Published: October 2022

AbstractElectrocatalytic CO2 reduction (eCO2RR) is one of the avenues with most potential toward achieving sustainable energy economy and global climate change targets by harvesting renewable energy into value‐added fuels and chemicals. From an industrial standpoint, eCO2RR provides specific advantages over thermochemical and photochemical pathways in terms of much broader product scope, high product specificity, and easy adaptability to the renewable electricity infrastructure. However, unlike water electrolyzers, the lack of suitable cathode materials for eCO2RR impedes its commercialization due to material design challenges. The current state‐of‐the‐art catalysts in eCO2RR suffer largely from low reaction rates, insufficient C2+ product selectivity, high overpotentials, and industrial‐scale stability. Overcoming the scientific and applied technical hurdles for commercial realization demands a holistic integration of catalytic designs, deep mechanistic understanding, and efficient process engineering. Special emphasis on mechanistic understanding and performance outcome is sought to guide the future design of eCO2RR catalysts that can play a significant role in closing the anthropogenic carbon loop. This article provides an integrative approach to understand principles of robust eCO2RR catalyst design superimposed with underlying mechanistic projections which strongly depend on experimental conditions viz. choice of electrolyte, reactor and membrane design, pH of the solvent, and partial pressure of the CO2.

AbstractAs promising cathode for sodium‐ion batteries, Na+ Superionic Conductor (NASICON)‐type materials have attracted attention owing to their excellent structural stability, superior ionic conductivity, and small volume expansion. However, the vanadium‐based NASICON‐type cathode with the biotoxicity and exorbitant price of V element and the iron‐based cathode with low mean working voltage as well as the intrinsic poor electronic conductivity of polyanionic compounds hinder their practical applications. Herein, a double‐carbon‐layer decorated heterogeneous composite, Na3V2(PO4)3‐Na3Fe2(PO4)(P2O7) (NVFPP/C/G), is successfully prepared for addressing these limitations. Due to their synergistic effect, NVFPP/C/G exhibits excellent electrochemical performance in half‐cell system and superior full‐cell performance when matched with hard carbon anode. Furthermore, the phase composition, electrode kinetics, and phase transition are confirmed by combined analyses of slow scanning power X‐ray diffraction, high‐resolution transmission electron microscopy, cyclic voltammetry with various scan rates, galvanostatic intermittent titration technique, ex situ X‐ray photoelectron spectra, and in situ X‐ray diffraction. This study portends a promising strategy to utilize composite structure engineering for developing advanced polyanionic cathodes.

Published: October 2022

AbstractOsteomyelitis caused by methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infection is difficult to eradicate and can even be life‐threatening. Given that the infection is persistent and deep‐seated in the bone tissue, controlled and efficient treatment of osteomyelitis remains challenging. Herein, an activatable nanostructure (Au/TNT@PG) is presented for synergistic sonodynamic‐catalytic therapy of MRSA‐infected osteomyelitis. The Au/TNT@PG backbone is obtained by conjugating a guanidinium‐rich polymer (PG), a component that penetrates the biofilm matrix, onto ultrasound (US)‐absorbing gold‐doped titanate nanotubes (Au/TNTs). Under deep‐penetrating US irradiation, the nanocomposite generates 1O2 for sonodynamic therapy and catalyzes the decomposition of endogenous H2O2 into toxic •OH in the acidic infection microenvironment for catalytic therapy, leading to bacterial cell death. Its robust antibacterial effectiveness is attributable to its bacteria‐capturing ability, the biofilm penetrability of positively charged guanidinium, and the subsequent synergistic effect of sonodynamic‐catalytic action of Au/TNT. Such a remotely controlled approach potentiates the polarization of macrophages to M2‐type while suppressing the M1‐type, leading to topical inflammation resolution and enhanced osteoblast proliferation and differentiation to inhibit bone loss. Therefore, this study provides a generic nanotherapeutic approach for efficient sonodynamic‐catalytic therapy with respect to osteomyelitis.

AbstractSolid electrolyte interphase (SEI) on Zn anodes plays a pivotal role for high‐rate and long‐life aqueous batteries, because it effectively inhibits side reactions and dendritic growth. Many materials are explored as SEIs by a trial‐and‐error approach. Herein, an exercisable way is proposed to screen the potential SEIs on Zn anodes in view of dendrite‐suppressing ability and charge‐transfer property theoretically. As an output of this screening, Zn3(BO3)2 (ZBO) is checked experimentally. In symmetrical cells, Zn@ZBO runs over 250 h at an ultrahigh current density of 50 mA cm−2 for a large areal capacity 10 mAh cm−2. In full cells, Zn@ZBO||MnO2 shows an impressive cumulative capacity (≈406 mAh cm−2) under harsh conditions, i.e., a lean electrolyte condition (10 µL mAh−1), limited Zn supply (negative/positive electrode capacity ratio, N/P ratio = 2.3), and high areal capacity (5.0 mAh cm−2). The significance of this work lies in not only the first report of ZBO on Zn showing excellent electrochemical performance, but also a feasible way to screen the promising SEI materials for other metal anodes.

Published: October 2022

AbstractPhotocatalytic H2O2 and H2 evolution are the sustainable alternative to meet the energy crisis. To fabricate an efficacious photocatalyst, here a robust MOF‐derived porous C/N co‐doped ZnO nano‐granular particles modified via in situ coupling with NixPy cocatalyst is developed. C and N are doped in ZnO via calcination of Zn‐MOF that narrows the bandgap of ZnO as verified by UV–vis DRS. More in, NixPy acts as robust cocatalyst, which enhances light absorption ability in the visible region. The existence of C, N, and Ni–P components along with their tremendous charge carrier dynamics are confirmed from XPS, PL, TRPL, and electrochemical analysis, respectively, that enhances the photoctalytic activity effectively. Hence, the H2O2 production rate and H2 evolution rate for optimized composite C/N‐ZNP‐2 are observed to be 2495.1 ± 62.3 µmol h−1 g−1and 12265 ± 112.4 µmol h−1 g−1, which are 2.8 and 2.7 folds higher than C/N‐ZnO, respectively. Additionally, the PO bond helps in inhibiting the further decomposition of H2O2. Consequently, the porous nature as well as larger surface area along with the presence of NixPy cocatalyst in C/N‐ZnO facilitates the overall reaction mechanism, hence paving the path for a robust photo‐catalyst towards sustainable energy generation.

AbstractThe emergent transient electronics that can be destroyed or degraded harmlessly under an environmental stimulus are attracting extensive attentions toward eco‐friendly electronic devices and confidential communication applications. However, currently available transient electronics are limited by the poor recyclability of components, which fails to meet the ever‐increasing demands of advanced electronic devices. Here, this work reports a fully recyclable transient electronic device based on a multi‐layered architecture, comprising a liquid metal (LM) as the conductor and a NaOH solution‐embedded paraffin composite (NPC) as the degradation agent. Upon thermally triggered by the bottom heater, the middle‐layer LM circuit and the top NPC layer melt, releasing the aqueous alkali to destroy the circuit at a quick transient rate (46 ± 4 s). Afterward, both the free LM and paraffin are recycled at extremely high efficiencies, that is, 98% for LM owing to the self‐aggregation and fluidic nature, 95% for paraffin arising from the low melting point and good recoverability. The successful integration of transience and recycling abilities dramatically improves the feasibility of transient electronics in real applications, as further demonstrated in a radio‐frequency transmission device and a remote destructible memristor, which hold great promises for confidential data storage devices and next‐generation electronics.

AbstractWhereas crystalline TiO2 is widely used as a photocatalyst for solar energy conversion, the use of amorphous TiO2 is limited by diminished performance. Herein, the highly active photocatalyst composed of low‐crystalline TiO2 prepared by simple heat treatment of amorphous material is reported. Transmission electron microscopy, X‐ray diffraction, Raman, X‐ray absorption spectroscopy, and scanning transmission electron microscopy show that the low crystalline catalyst is hetero‐phase amorphous/anatase (mamorphous: manatase ≈ 2:3). Enhanced photocatalytic performance derives from the difference in conduction band potential between the phases, which promotes charge transfer and photochemical conversion. The photocatalyst calcined at 300 °C (T‐300) exhibits superior performance over commercial P25 (Degussa) for elimination of perrhenate, Re(VII), a surrogate for Tc(VII), and furthermore remains stable after several recycles. The high efficiency of Re(VII) removal by T‐300 is likely to correlate with active radicals ∙CO2− in the TiO2/HCOOH system. In addition to identifying a simple and effective photocatalyst, the results more generally elucidate titania‐based photocatalysis.

AbstractWearable technologies are becoming important for the fields of information technology and healthcare, driven mainly by societal issues such as the aging society and the current pandemic. Recently developed flexible/stretchable wearable devices have demonstrated their ability for long‐term healthcare monitoring with improved signal integrity and multimodality. However, the adherence of wearers to such wearable devices cannot be determined only by the function. Here “comfort‐of‐wear” is identified as one of the most critical parameters for future wearables, similar to how clothes are chosen based on how comfortable they are. “Comfort‐of‐wear” is defined as the device's ability to not to disturb the wearers’ daily life. Several engineering approaches are introduced to improve the comfort‐of‐wear of devices—via strategies that include improving flexibility by utilizing a combination of structures, materials, and systems. Finally, the future of wearables enabled by cutting‐edge advanced electronic technologies is proposed.

AbstractMultiply twinned icosahedrons possess a diversity of unique functionalities well‐suited to various applications, such as thermoelectric conversion. Regarding chalcogenide icosahedron, an unconventional yet promising thermoelectric candidate, disclosing its growth mechanism is rather challenging. This study uncovers the formation mechanism of thermoelectric Cu5+3xFe1‐xS4 (0 ≤ x ≤ 0.4) core‐shell nano‐icosahedrons, which is distinct from that of well‐known metal icosahedrons. Electron microscopy and molecular dynamics simulations reveal that the evolution into icosahedrons, stemming from the fivefold twin formation in the center of Cu5FeS4 particle aggregates, is accompanied by the gradual formation of Fe‐rich orthorhombic‐structured core and Cu‐rich cubic‐structured shell, which provides a peculiar stress relaxation mechanism. Further identified by density functional theory calculations, Fe atoms have the tendency to transform cubic Cu5FeS4 to its orthorhombic phase and in turn result in varied crystal structures and lattice parameters in the core and shell. Importantly, by adjusting the Cu/Fe ratio of the precursors, the stress‐releasing process and potential energy of icosahedrons are controllably tuned, generating Cu5+3xFe1‐xS4 icosahedrons with tunable diameters. Accordingly, a significantly enhanced thermoelectric zT of 0.90, the largest value for Cu5FeS4, is realized. This study will shed light on the design strategy for Cu‐based ternary chalcogenide icosahedrons with enhanced thermoelectric properties.

Published: October 2022

AbstractWe report novel transport phenomena arising from an interface between two immiscible liquids in a laminar flow. In the context of the Taylor–Aris dispersion theory, we provide a quantitative description and demonstrate that the planar interface between two liquids in a laminar flow can lead to uphill advection and dispersion, dispersion barrier, as well as osmotic dispersion. The developed understanding of the newly identified transport phenomena paves the way for further research in this area and enables the insightful elucidation of mixing and separation processes in multiphase systems.
Minimum reflux calculation for multicomponent distillation in multi‐feed, multi‐product columns: Mathematical model
Authors: Jiang Zheyu , Tawarmalani Mohit , Agrawal Rakesh 
Published: October 2022

AbstractMulti‐feed, multi‐product distillation columns are ubiquitous in multicomponent distillation systems. The minimum reflux ratio of a distillation column is directly related to its energy consumption and capital cost. Thus, it is a key parameter for distillation systems design, operation, and comparison. In this series, we present the first accurate shortcut based algorithmic method to determine the minimum reflux condition for any general multi‐feed, multi‐product (MFMP) distillation column separating any ideal multicomponent mixture. The classic McCabe‐Thiele or Underwood method is a special case of this general approach. Compared with existing techniques, this method does not involve any rigorous tray‐by‐tray calculation, nor does it require guessing of key components. In this first part of the series, we present the mathematical model for a general MFMP column, derive constraints for feasible separation and minimum reflux condition, discuss their geometric interpretations, and present an illustrative example to demonstrate the effectiveness of our approach.

AbstractMeasurable residual disease (MRD) is a powerful prognostic factor in acute myeloid leukemia (AML). However, pre‐treatment molecular predictors of immunophenotypic MRD clearance remain unclear. We analyzed a dataset of 211 patients with pre‐treatment next‐generation sequencing who received induction chemotherapy and had MRD assessed by serial immunophenotypic monitoring after induction, subsequent therapy, and allogeneic stem cell transplant (allo‐SCT). Induction chemotherapy led to MRD− remission, MRD+ remission, and persistent disease in 35%, 27%, and 38% of patients, respectively. With subsequent therapy, 34% of patients with MRD+ and 26% of patients with persistent disease converted to MRD‐. Mutations in CEBPA, NRAS, KRAS, and NPM1 predicted high rates of MRD− remission, while mutations in TP53, SF3B1, ASXL1, and RUNX1 and karyotypic abnormalities including inv (3), monosomy 5 or 7 predicted low rates of MRD− remission. Patients with fewer individual clones were more likely to achieve MRD− remission. Among 132 patients who underwent allo‐SCT, outcomes were favorable whether patients achieved early MRD− after induction or later MRD− after subsequent therapy prior to allo‐SCT. As MRD conversion with chemotherapy prior to allo‐SCT is rarely achieved in patients with specific baseline mutational patterns and high clone numbers, upfront inclusion of these patients into clinical trials should be considered.
