This study thoroughly analyzes the effects of formic acid (FA) on various aspects, including growth rate, crystal structure, substrate selection, film formation, gas sensitivity, and parameters influencing power conversion efficiency. Several analytical methods, such as scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, Raman spectroscopy, UV-Vis spectrophotometry, and a Solar sun simulator, are employed to assess the efficiency of the photovoltaic system under the effect of the acid mixture. Nanorod arrays (NRAs) formed by combining hydrochloric acid (HCl) and FA solution show significantly better performance compared to those formed using HCl solution alone. The findings suggest that adding FA to the growth solution results in improved uniformity and density of titania NRAs. Consequently, this leads to a larger surface area to adsorb dye molecules in dye-sensitized solar cells or sense target gas in a gas sensor device. This improvement is attributed to the enhancement of both optical and electrical characteristics of the fabricated films and device performance.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, traditional cascaded topologies have many challenges, such as large input current ripple, limited voltage level generation, and complex interfacing between direct current (DC)–DC boost stages and alternating current (AC) output stage. Such constraints impair the general operation and effectiveness of these systems. The proposed work introduces a modified multistage converter-fed cascaded multilevel inverter configuration aimed at enhancing the performance and efficiency of multilevel inverters for modern power applications. The presented topology includes three main stages: a multistage boost converter, level shifter and H-bridge. The enhanced multistage converter efficiently produces multiple voltage levels at the load while reducing the input inductor current. The level shifter circuit seamlessly connects the boost converter to the H-bridge and delivers a unidirectional multilevel voltage. The H-bridge converted the input into multilevel AC voltage. The design features a hybrid input setup with dual voltage sources, examining both single- and dual-input scenarios. Comprehensive simulation results are presented for both boost converter and inverter functions. A hardware prototype validated the simulation findings, demonstrating the practical viability of the proposed multistage converter-fed multilevel inverter in real-world applications.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This material enhances photothermal effects and is engineered for highly stretchable, durable, and floatable broadband light absorption. Combining CNT-based inherent light absorption and the 3D mogul pattern with micro-cavities effectively captures a broad spectrum of light from ultraviolet (UV) to near-infrared (NIR) of (250–1500) nm, achieving an average absorption of 98%. Uniform CNT distribution in Ecoflex elastomer on the 3D mogul pattern reduces stress concentration, ensuring a robust, elastic platform. This platform withstands stretching, deformation, intense pulsed light, and salt-aging without compromising optical properties across the UV–vis–NIR range. Under a 1-sun solar simulator, the structure's photothermal effect is evident, reaching 74.6 °C. The floatable nature of the composite makes it ideal for solar desalination, achieving a 0.52 kg m−2 h−1 evaporation rate under 1-sun. Furthermore, the curved CNT–Ecoflex mogul structure embedded in ice melts within 30 min under 2 sun exposure, regaining its flat, stable form.

Herein, eight new A-D-π-A type SM-NFAs PS-1 to PS-8, having an indacenodithiophene central core, are designed. These designed materials and a synthetic reference molecule (PS) are characterized using various advanced quantum chemical approaches. The theoretical analysis investigated the structure-property relationship, optical, optoelectronics, and photovoltaic characteristics of synthetic PS and modeled PS-1 to PS-8 molecules. Moreover, the electron-hole overlapping, frontier molecular orbitals, excitation energy, dipole moment, binding energy, molecular electrostatic potential, density of states, heat map, transition density of states, and reorganization energies of the hole and electrons are specifically investigated. These modeled PS-1 to PS-8 series showed narrower energy gaps, decreased binding energies, and improved absorption characteristics. Among these, the modeled PS-2 molecule shows a narrow energy gap (Eg) of 1.79 eV and enhanced absorbance of 877.45 nm compared to the synthetic reference PS molecule (Eg 2.02 eV and absorption 741.58 nm). Moreover, a thorough analysis of the PS-2/PTB7-Th complex demonstrates efficient charge transfer at the donor-acceptor interface. Therefore, it is believed that the proposed molecules PS-1 to PS-8 could be efficiently employed in preparing highly efficient organic solar cells (OSCs).","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that among all the investigated electrolytes CFx exhibits the highest capacity with the value as high as 827 mAh g−1 under alkaline NaOH electrolyte environment, and corresponding maximum capacity can also reach 632, 607, 352, and 66 mAh g−1 under those weak alkaline (sodium and potassium salts) and weak acid (zinc salts) electrolyte environment.

The rate of surface exchange electrons processes plays an important role in the formation of the electrophysical properties of materials. It is studied an effect of oxygen-free graphene sheets on the activity of nanostructured ceria and zirconia in oxidation–reduction processes, where the rate of surface exchange electron interactions plays a key role. The reaction of CO oxidation is chosen as a model. It is shown that the introduction of oxygen-free graphene sheets up to 3 nm thick into ceria or zirconia nanopowders leads to a decrease in the CO oxidation temperature. Apparently, this effect is caused by the formation of highly active centers with elongated terminal MO bonds in the presence of the sp2-electron system of graphene. It is found that graphene increases the ability of metals to reversible oxygen exchange. The introduction of oxygen-free graphene into the MnxOy/CeO2 system leads to acceleration of surface exchange processes due to the facilitation of electron transfer in the system as a whole.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential to understand in depth how the triboelectric properties of materials and operating conditions change TENG performance to improve their electrical outputs. In this study, the effects of various material parameters and operating conditions on the voltage, current, and power outputs of the TENGs are numerically investigated. The surface charge density improves the performance of the TENGs at all load resistances, while dielectric thickness, dielectric constant, surface area, and separation velocity are effective at medium and low load resistances. The separation distance, unlike all these, decreases performance at low load resistances. However, at high load resistances, it has the opposite effect and improves the performance. Furthermore, a broad range of data obtained from numerical simulations is used to train a machine learning-based TENG simulator. This simulator is based on a multilayer perceptron (MLP) model with an input layer of nine neurons, two hidden layers, one with nine neurons and the other with 55 neurons, and an output layer of three neurons for predicting current, voltage, and power. The MLP model, trained using TensorFlow, demonstrates high accuracy with R² values over 0.99 and achieves remarkably low mean absolute percentage error (MAPE) values of 4.22%, 3.35%, and 7.57% for current, voltage, and power predictions, respectively.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, an already existing Ruddlesden–Popper (R–P) structure of tungstic acid variants as a generic framework to achieve ultrastable HOIPs, serving as stable and safer alternatives to lead-based HOIPs in aqueous electrochemical devices, is introduced. An enormous improvement (of the tungsten-based framework) in electrochemical performance is achieved by converting electrochemically sluggish H2W2O7 to oxygen-deficient H2W2O7−δ to leverage a facile and reversible W6+ → W5+ transition along with local defect-mediated H+ insertion/extraction. This local structural modification results in a remarkable pseudocapacitive performance (specific capacitance of ≈622 F g−1 or specific capacity 155.5 mAh g−1 at 64 C) with no observable capacity fade (≈100% specific capacity retention after thousands of cycles) in 0.5 m H2SO4 aqueous solution. To extend the scope of utilization of this R–P phase in aqueous electrochemical energy storage devices, OA2W2O7−δ (OA = octylammonium), a HOIP, which similarly displays impressive EES performance is synthesized. Most importantly, when used as an electrode material, this HOIP exhibits remarkably high stability in aqueous acidic electrolyte.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
