In this study, we present a promising iron-doped manganese sulfide electrocatalyst consisting of three-dimensional microarchitecture surfaces that exhibit efficient hydrogen evolution activity in an alkaline electrolyte. Iron doping induces surface regulation in MnS promoting the growth of various morphologies from 3D microarchitectures to 2D sheets. The 3D architecture, coupled with abundant active sites and iron incorporation, promotes hydrogen adsorption in manganese sulfide. The influence of iron doping on the hydrogen evolution activity of manganese sulfide was systematically investigated. The Mn<sub>0.95</sub>Fe<sub>0.05</sub>S electrocatalyst, with optimized iron incorporation, demonstrated a low overpotential of 147 mV to achieve a current density of 10 mA cm<sup>–2</sup> in a 1 M KOH electrolyte. Post-hydrogen evolution reaction characterizations revealed Mn<sub>0.95</sub>Fe<sub>0.05</sub>S @FeMnOOH<sub><i>x</i></sub>S<sub><i>y</i></sub>, which were observed to be active catalysts enhancing the hydrogen evolution activity.

These characteristics, attributed to the internal structure of the material, significantly affect their adsorption performance. In this research study, we created a data set and collected data points from porous adsorbents (2789) from 21 published papers, including carbon-based, porous polymers, metal–organic frameworks (MOFs), and zeolites, to understand their characteristics for CO<sub>2</sub> adsorption. Different machine learning (ML) algorithms, such as NN, MLP-GWO, XGBoost, RF, DT, and SVM, have been applied to display the CO<sub>2</sub> adsorption performance as a function of characteristics and adsorption isotherm parameters. XGBoost was selected as the best ML algorithm due to its highest accuracy (<i>R</i><sup>2</sup> = 0.9980; MSE = 0.0001). The predicted results revealed that the adsorption pressure parameter is the most effective in all of the mentioned porous adsorbents. With regard to materials type, while carbon-based materials require higher pressures for a more effective CO<sub>2</sub> adsorption, MOFs exhibit a higher potential for adsorbing CO<sub>2</sub> under lower pressure conditions. The study also revealed that carbon-based adsorbents, zeolites, and porous polymers with smaller pore diameters demonstrate a high level of CO<sub>2</sub> uptake. In contrast, the adsorption performance of MOFs does not show a consistent trend with respect to pore sizes. Also, in all adsorbents, the effect of a pore size smaller than 1 nm on more CO<sub>2</sub> adsorption was evident.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":null,"pages":null},"PeriodicalIF":6.4,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional sensor preparation processes are gradually unable to meet people’s needs for the portability, breathability, and biocompatibility of sensors. We prepared a high breathability flexible triboelectric nanogenerator (RB-TENG) using electrospinning technology. Polyvinylidene fluoride (PVDF) was selected as the material for preparing the electron gain side friction layer of RB-TENG, while a conductive solution was prepared using thermoplastic polyurethane (TPU) and carbon black (CB) as its electron losing side friction layer and electrode layer. To enhance the output performance of the RB-TENG, we increased the surface charge density of its friction layer by doping carbon black (CB) into the polyvinylidene fluoride (PVDF) solution. We then evaluated how varying CB concentrations influenced the device’s output. Our findings revealed that when the CB concentration reached 1.2 wt %, the RB-TENG achieved its optimal performance, with peak open-circuit voltage and transfer charge values of 149.2 V and 176.5 nC, respectively. Additionally, the RB-TENG demonstrated the ability to detect different physical states of the human body while efficiently harvesting the generated energy. By integrating a capacitor conversion circuit, the mechanical energy produced during daily human activities can be efficiently captured and converted into electrical energy. This significantly enhances the efficiency of RB-TENG in charging capacitors, enabling the rapid powering of microelectronic devices. The RB-TENG-based energy harvesting and intelligent sensing system we designed holds significant theoretical and practical value for wearable electronics. The technology presented in this paper offers promising applications for a wide range of wearable devices.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":null,"pages":null},"PeriodicalIF":6.4,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the introduction of task-specific ionic liquid (IL) tetramethylguanidine lactate (GuLAC) demonstrates excellent defect passivation effects and crystal growth. More specifically, the formation of hydrogen bonds between –NH<sub>2</sub> in GA<sup>+</sup> and I<sup>–</sup> passivates cation defects, while strong chemical interaction of lactate anion passivates the undercoordinated Pb<sup>2+</sup>. Both experimental observations and theoretical simulation confirm the strong interaction of GuLAC with the perovskite, which is responsible for restricting ion migration, improving grains’ size, and elongating the carrier lifetime. As a result, the IL-modified device exhibits improved PCE and superior long-term stability compared to the control device.

In the work, a polytriphenylamine derivative of polyphenylaniline (P(PhAn)) with a polyaniline-like molecular backbone structure was prepared by Buchwald-Hartwig C–N coupling reaction, and its electrochemical performances were evaluated in detail as the lithium organic cathode material. P(PhAn) as cathode displayed the multielectron redox characteristic, in which two pairs of redox characteristic peaks occurred in the measured voltage range.

Phen-A functionalized ZnO has the lowest WF, which can be attributed to the effective donation of nitrogen lone pairs to the Zn center thereby effectively raising the Fermi energy of the system.
