Adolescents’ advertising literacy and body self-perception in the face of influencer marketing
Authors: Feijoo Beatriz , Sádaba Charo
Published: January 2025

En la sociedad actual, la gente está cada vez más preocupada por su cuerpo y los profesionales del marketing son muy conscientes de ello. Como resultado, los influenciadores han empezado a incorporar contenido con un protagonismo especial del cuerpo y de la apariencia, especialmente cuando al promocionar marcas de moda, alimentación, cosmética, belleza o fitness. Esto, junto con la incidencia que el estilo de vida de los influenciadores tiene en la imagen corporal de los usuarios, hace necesario un análisis más detallado de las medidas que pueden proteger al público, principalmente a los jóvenes, del impacto de estas publicaciones que, a menudo, desdibujan los límites entre el contenido orgánico y el patrocinado. Este estudio plantea la posibilidad de que uno de estos filtros para proteger a este grupo de edad de los contenidos patrocinados de influenciadores que explotan el argumento de la imagen sea su nivel de alfabetización publicitaria. Mediante una encuesta aplicada a 1055 adolescentes de 11 a 17 años residentes en España entre abril y junio de 2022 se pudo comprobar la relación significativa entre la preocupación de los adolescentes por su imagen corporal y su nivel de alfabetización publicitaria ante estos contenidos, especialmente en el establecimiento de metas para conseguir el cuerpo perfecto y la importancia del aspecto físico en su autopercepción. El género, la edad y el nivel socioeconómico de los encuestados introducen matices en los resultados. La discusión es relevante para empresas que incluyen influenciadores en sus estrategias de marketing, familias, educadores y administraciones públicas.

Published: January 2025

El artículo aborda la cobertura periodística de las protestas estudiantiles en el Instituto Nacional de Santiago, Chile, en 2019, centrándose en cómo dos diarios de referencia de circulación nacional, El Mercurio y La Tercera, enmarcaron estos eventos. Se analizó la representación de las movilizaciones en 135 textos de opinión y noticias publicados entre abril y octubre de 2019, a partir de lo cual se realizó una selección para estudiar los encuadres desde un enfoque cualitativo. Los resultados muestran que los medios analizados enfatizaron los actos de violencia y de desorden, desatendiendo las causas fundamentales de las protestas, lo que contribuyó a formar una imagen negativa de los estudiantes. La discusión recalca cómo estos relatos periodísticos pueden perpetuar estereotipos y obstruir el entendimiento de problemas estructurales significativos en la educación. Asimismo, el artículo releva la responsabilidad de los medios en modelar la realidad social y la necesidad de un enfoque más equilibrado que promueva un debate público informado y constructivo acerca de los conflictos de la educación en Chile.

Published: January 2025

Aim: Metabolic illnesses such as milk fever and ketosis in dairy cattle significantly impact productivity and production efficiency, thereby hindering farmers' ability to enhance their income. This study aimed to systematically evaluate the financial implications of metabolic disorders in dairy cattle, providing critical insights into their economic burden on dairy farming systems.
Place and Duration of Study: Kheri district, Uttar Pradesh, 6 months – March 2024 to June 2024.
Methodology: A total number of 60 dairy farms were chosen out of which 30 farms were affected by milk fever and 30 by ketosis randomly in Kheri district of Uttar Pradesh. The data on the socio-economic profile of the farmers along with the predisposing factor and the data on direct and indirect economic losses caused by ketosis and milk fever, cost of medicine, cost of veterinary services, cost of supplements and loss in milk yield have been considered.
Results: The average total economic loss was found as Rs 1,736.10 per cow and Rs 2,790.25 per cow due to milk fever and ketosis respectively. The factors associated with the economic losses due to ketosis and milk fever was estimated by fitting multiple linear regression function models. Among the eight factors chosen for model definition, the variables, viz., breed of cow (P<0.05), milk yield (P<0.01), veterinary care (P<0.05) and the days of illness (P<0.05) were found to have statistically significant association with the economic losses due to milk fever and Ketosis.
Conclusion: Metabolic illnesses such milk fever and ketosis result in higher financial losses since they lower productivity, raise veterinary expenses, and have an impact on market profitability. The relevance of incorporating economic, health and welfare factors into livestock management practices is highlighted by the fact that treating metabolic diseases not only lessens financial costs but also enhances food security and animal wellbeing.

Published: January 2024

The majority of natural organisms interact with their environments with a degree of mechanical adaptability that allows them to carry out a variety of tasks and adapt to changing circumstances. Human‐made structures, however, lack this versatility and are normally designed to fulfill a certain load‐carrying requirement. This causes limitations in performance, efficiency, and safety. The aim of this article is to present rapid de‐stiffening in the response of conventional structures, without compromising the load‐bearing capacity. This has been achieved by developing an active interface using an interconnected nanostructured metallic network. A very fast heating rate with an average of ≈45 °C s−1 under 4.8 V excitation while retaining transparency of 67% is demonstrated. The embedded metallic network in a thermoplastic matrix has been deployed as an active interface, in a conventional transparent multilayered structure. Upon activation, it provides a rapid (i.e., 2 s after activation) mechanical de‐stiffening capability. The results from finite element modeling have been found to be in good agreements with those from experiments. The rapid reversible stiffness tuning demonstrated here can be implemented in variety of multilayered structures with a wide range of applications in robotics, morphing and deployable structures, active damping, and active impact safety systems.

Published: January 2024

Stimuli‐responsive photoluminescent (PL) materials have attracted considerable attention in recent years owing to their potential applications in anti‐counterfeiting, information encryption, and sensing. Further investigations of the transformation mechanism and potential applications of stimulus‐responsive PL materials are considerably important. In the current study, an organic–inorganic metal halide, C9H15N3SbCl5 ([C9H13N3]2+ is a 1‐(2‐pyridyl) piperazine cation) is obtained, which exhibits a 0D structure with P‐1 space group. At room temperature, when excited by UV light, the C9H15N3SbCl5 single crystals exhibit unimodal blue light emission at 405 nm, and grinding or hydrostatic pressure induces double‐peak emissions at 405 and 650 nm. Interestingly, double‐emission samples can be restored to single‐emission samples by short annealing or storage in air for 2 weeks, and this process is reversible. Luminescence response to mechanical stimuli can also be achieved in the presence of hydrochloric acid and water. Spectral analysis and the analysis of the microstructural changes revealed that the structural modifications of the inorganic group play a pivotal role in the response to the stimulus. Finally, a composite film device based on C9H15N3SbCl5 is prepared to demonstrate the potential of these smart materials in anti‐counterfeiting and sensing applications.

Published: January 2024

An ideal thermoelectric material requires the multi‐valley and strong dispersion band structure, for relieving the competition between thermopower and electrical conductivity, whereas the two features barely coexist in natural compounds. Here, the significantly improved thermoelectric performance in n‐type PbSe‐xAgSbS2 with the purposefully renormalized conduction band structure is reported. It is shown that the strong spin‐orbit coupling effect splits the single valley at “L” point into three individuals delicately, as the Dirac point is shifted away from the high symmetry point by the decreasing lattice constant. Compared with the common PbSe‐based compounds, the renormalized system exhibits a range of distinctive properties, such as the 2–3 times larger band gap, 5–10 times lower optimal carrier concentration, and weakly temperature‐dependent Seebeck coefficient. Owing to the achieved giant band convergence and the low thermal conductivity, a high peak zT of 1.75 at 850 K and an outstanding average zT of 1.04 are obtained. Furthermore, the mechanical property and thermal stability of PbSe are considerably improved for the introduced high entropy effect and lattice shrinkage. This study reveals the remarkable impact of spin‐orbit coupling on thermoelectric performance, and suggests that the optimized PbSe material holds great promise for practical applications.
An Electrically Tunable Dual‐Mode Laser Based on Self‐Assembled Soft Photonic Liquid Crystals
Authors: Tsao Yu‐Chuan , Chen Hui‐Yu , Chen Yang‐Fang
Published: January 2024

Soft photonic liquid crystals with electrically responsive properties are among the most promising intelligent materials for optoelectronic applications. This work demonstrates an ultra‐fast electrically tunable dual‐mode laser by introducing dye‐doped chiral liquid crystals. Due to the strong chirality of the chiral liquid crystal, two self‐assembled structures form depending on the temperatures. One is the chiral nematic phase (N*) with a 1D helical structure; the other is the blue phases (BPs) with 3D cubic structures. By tuning the strength of an electric field, the dye‐doped chiral liquid crystals are operated in two different modes: a band‐edge laser and a random laser. In the band‐edge mode, due to the electrostriction effect of the BPs, the electric‐tuning range of the laser emission is from 537 to 645 nm, and the switching times are less than 20 ms. When the electric field goes beyond a threshold value to force the occurrence of the BPs‐chiral‐nematic transition, the band‐edge laser with elliptical polarization emission is switched to a random laser with an immediate unpolarization emission (0.9 ms). Furthermore, the reversibility of the effects mentioned above points out the potential applications of self‐assembled soft photonic materials, spanning from solid‐state lighting to bio‐imaging.

Published: January 2024

Circularly polarized light (CPL) detection has sparked the booming interest for versatile chiral‐optoelectronic and spintronic devices. For practical device applications, a large asymmetry factor is required to distinguish the handedness of incent light. However, for most chiral CPL active candidates, the difference in optical density or absorption anisotropy is quite subtle under CPL illumination, resulting in a relatively low asymmetry factor (usually ≤ 0.2). Up to date, it remains extremely challenging to achieve CPL response in the achiral crystals. Inch‐size achiral perovskite‐type crystals of (IBA)2(EA)2Pb3I10 (IBA = 4‐isopropylbenzylammonium, EA = ethylammonium), which holds a promise to distinguish CPL with a large asymmetry factor up to ≈0.56 at 405 nm is presented here. This figure‐of‐merit is comparable or even superior than most of those chiral counterparts. Further First‐principles calculations disclose such CPL‐active behaviors of (IBA)2(EA)2Pb3I10 are associated with the splitting of its band spin‐degeneracy, induced by the breaking of inversion symmetry and spin‐orbital coupling (SOC) effects. As far as it is known, the structural origin of CPL‐activities of (IBA)2(EA)2Pb3I10 is completely distinctive from the conventional chiral family, which paves a promising pathway to explore new candidates toward high‐performance CPL detection.

Photocatalytic uranium extraction from seawater is an ideal strategy to obtain uranium resources. Herein, the cyano‐functionalized graphitic carbon nitride (g‐C3N4‐CN) with an isosite structure of adsorption and photoreduction for U(VI) is successfully prepared to achieve efficient photocatalytic uranium extraction from seawater. As the key of the isosite structure, the cyano group not only dramatically promotes the separation of photogenerated charges of g‐C3N4‐CN and enriched electrons around it, but also greatly improves the adsorption capacity and selectivity for U(VI) over g‐C3N4‐CN by complexing with U(VI). Therefore, g‐C3N4‐CN exhibits efficient and stable photocatalytic U(VI) reduction performance, with a saturated uranium extraction capacity of 2644.3 mg g−1, significantly higher than most reported g‐C3N4‐based photocatalysts. Moreover, it also performs well in solar light‐driven uranium extraction from actual seawater. Briefly, this work illustrates the importance of constructing the isosite structure of adsorption and photoreduction for U(VI) in improving the photocatalytic uranium extraction performance.

Published: January 2024

Active and durable catalysts for hydrogen evolution reaction (HER) are of great significance for developing renewable hydrogen energy. Herein, crystalline/amorphous‐Ru/VOx (c/a‐Ru/VOx) heterogeneous catalysts are conceived, in which the amorphous VOx exposes more active sites and enhances charge transport compared with the counterpart with a crystal phase structure, strengthening the electronic interaction between metal‐support. As expected, c/a‐Ru/VOx‐500 with heat treatment at 500 °C exhibits excellent HER performance under alkaline conditions, with an overpotential of only 33 mV at 10 mA cm−2 and small Tafel slope (27 mV dec−1), superior to commercial platinum/carbon (Pt/C) catalysts. Particularly, its mass activity (0.335 A mgRu−1) is 1.5 times greater than that of Pt/C (0.224 A mgPt−1) at an overpotential of 50 mV. Also, it shows good industrial application prospects through tests under high temperature, high alkalinity, and large current conditions. Theoretical calculations unveil that there exists a charge redistribution at c/a‐Ru/VOx heterointerfaces, which makes the surface of Ru takes on an electron‐deficient state, resulting in optimization of adsorption and desorption for different reaction intermediates. This optimized behavior effectively reduces the thermodynamic energy barrier, allowing the catalyst with greatly enhanced HER performance. The exploration provides a promising strategy for designing efficient and durable catalysts for HER.

High‐concentration electrolyte effectively improves the energy density and anti‐freezing property of aqueous micro‐supercapacitors (MSCs), endowing them the opportunity serving as power sources for miniaturized electronics. However, the excessive usage of salt significantly increases the cost of the electrolyte. Herein, a cost‐effective moderate‐concentration hybrid electrolyte is designed by introducing CaCl2 and ethylene glycerol (EG) additives for low‐temperature and high‐voltage MSCs. The results manifest that the introduction of CaCl2 minimizes the number of water molecules with strong hydrogen bonds while the addition of EG can reduce the amount of H2O molecules in the primary solvation shell sheath of Ca2+ ion and strengthen the hydrogen bonds between EG and water molecules, thus endowing the optimal electrolyte with a wide electrochemical stability window of 3.5 V and a freezing point lower than −120 °C. Furthermore, the resulting hybrid MSCs offer a high voltage of 1.6 V, and realize 62% capacitance retention at −40 °C compared to that at room temperature. Moreover, The MSCs can endure 20000 cycles with 98.5% capacitance retention at −40 °C. This work provides a meaningful guidance for designing low‐cost moderate‐concentration hybrid electrolyte with wide electrochemical stability window and anti‐freezing property for intrinsically safe and environmentally adaptable devices.

Published: January 2024

The cGAS‐STING pathway represents a crucial DNA‐sensing mechanism that has shown promise as a target for overcoming immunoresistance in solid tumors. Mn2+ and Zn2+ play crucial roles in innate immune sensing of cytosolic dsDNA, ultimately resulting in the activation of cGAS‐STING pathway. Unfortunately, efficient delivery of these metal ions to target cells remains a challenge, limiting their effectiveness in activating the STING pathway. Herein, a novel strategy based on nanoscale coordination polymer (NCP)/polymer nano‐hybrids is presented, which enables effective co‐delivery of metal ions and chemotherapeutics to tumor tissues, thereby activating the cGAS‐STING pathway to induce strong anti‐tumor immune responses. In this strategy, NCPs are water‐insoluble under physiological conditions, enabling efficient loading of metal ions while minimizing leakage in the bloodstream. In addition, designing the ligands of the NCPs to respond to different biological signals can enable rapid dissociation and metal ions/drugs release specifically at tumor sites. With this strategy, metal ion‐drug combinations such as Mn2+/PTX and Zn2+/Fe3+/DOX are co‐delivered to tumor successfully, leading to the effective synergy between dsDNA generation by chemo‐drugs and cGAS sensitization by Mn2+ and Zn2+. This efficiently activates the cGAS‐STING pathway, thereby inducing the anti‐tumor immune response and effectively inhibiting tumor growth, recurrence, and metastasis.
Borate Anion‐Intercalated NiV‐LDH Nanoflakes/NiCoP Nanowires Heterostructures for Enhanced Oxygen Evolution Selectivity in Seawater Splitting

Published: January 2024

Resourceful and inexpensive seawater direct splitting omits the desalination process and effectively increases the efficiency of hydrogen energy generation. However, the development of seawater splitting is hampered by the competing selectivity challenges from anodic oxygen evolution reaction (OER) and chlorine evolution reaction and the issues of electrode corrosion. Herein, the borate anion‐intercalated NiV‐LDH nanoflakes/NiCoP nanowires heterostructures supported on Ni foam (2D/1D NiV‐BLDH/NiCoP/NF) is synthesized. Theoretical calculations show that a small amount of V atom doping in Ni(OH)2 is favorable for changing the electronic environment around Ni atoms via bridging Ni─O, which can construct Ni─O─V to accelerate electron transfer and promote catalytic activity. The borate anions (B(OH)4−) intercalation not only results in the good hydrophilicity and high OH− selectivity but also weakens the adsorption of chlorine (Cl−), which effectively restrains the chlorine evolution reaction. Thus, the component optimized NiV0.1‐BLDH/NiCoP/NF electrocatalyst only requires 268 mV overpotential to reach 100 mA cm−2 for OER in an alkaline environment. Particularly, the NiCoP/NF||NiV0.1‐BLDH/NiCoP/NF cell exhibits attractive overall water splitting performance with a low voltage of 1.46 and 1.53 V at 10 mA cm−2 in alkaline freshwater and alkaline seawater, respectively. The design strategy of this electrocatalyst provides a new avenue for seawater splitting.

Advanced battery electrodes require a cautious design of microscale particles with built‐in nanoscale features to exploit the advantages of both micro‐ and nano‐particles relative to their performance attributes. Herein, the dynamic behavior of nanosized Sn clusters and their host pores in carbon nanofiber) during sodiation and desodiation is revealed using a state‐of‐the‐art 3D electron microscopic reconstruction technique. For the first time, the anomalous expansion of Sn clusters after desodiation is observed owing to the aggregation of clusters/single atoms. Pore connectivity is retained despite the anomalous expansion, suggesting inhibition of solid electrolyte interface formation in the sub‐2‐nm pores. Taking advantage of the built‐in nanoconfinement feature, the CNF film with nanometer‐sized interconnected pores hosting Sn clusters (≈2 nm) enables high utilization (95% at a high rate of 1 A g−1) of Sn active sites while maintaining an improved initial Coulombic efficiency of 87%. The findings provide insights into electrochemical reactions in a confined space and a guiding principle in electrode design for battery applications.

Published: January 2024

Stretchable ionic hydrogels with superior all‐round properties that can detect multimodal sensations with excellent discriminability and robustness against external disturbances are highly required for artificial electronic skinapplications. However, some critical material parameters exhibit intrinsic tradeoffs with each other for most ionic hydrogels. Here, a microphase‐separated hydrogel is demonstrated by combining three strategies: (1) using of a low crosslinker/monomer ratio to obtain highly entangled polymer chains as the first network; (2) the introduction of zwitterions into the first network; (3) the synthesis of an ultrasoft polyelectrolyte as the second network. This all‐round elastic ionic hydrogel exhibits a low Young's modulus (< 60 kPa), large stretchability (> 900%), high resilience (> 95%), unique strain‐stiffening behavior, excellent fatigue tolerance, high ionic conductivity (> 2.0 S m⁻1), and anti‐freezing capability, which have not been achieved before. These properties allow the ionic hydrogel to operate as a stretchable multimodal sensor that can detect and decouple multiple stimuli (temperature, pressure, and proximity) with excellent discriminability, high sensitivity, and strong sensing‐robustness against strains or temperature perturbations. The ionic hydrogel sensor exhibits great potential for intelligent electronic skin applications such as reliable health monitoring and accurate object identification.

Published: January 2024

The conducting polymer poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) offers superior advantages in electronics due to its remarkable combination of high electrical conductivity, excellent biocompatibility, and mechanical flexibility, making it an ideal material among electronic skin, health monitoring, and energy harvesting and storage. Nevertheless, pristine PEDOT:PSS films exhibit limitations in terms of both low conductivity and stretchability; while, conventional processing techniques cannot enhance these properties simultaneously, facing the dilemma that highly conductive interconnected PEDOT:PSS domains are susceptible to tensile strain. Via modifying PEDOT:PSS with ionic liquids (ILs), not only a synergistic enhancement of the electrical and mechanical properties can be achieved but also the requirements for the printable bioelectronic are satisfied. In this comprehensive review, the task of providing a thorough examination of the mechanisms and applications of ILs as modifiers for PEDOT:PSS is undertaken. First, the theoretical mechanisms governing the interactions between ILs and PEDOT:PSS are discussed in detail. Then, the enhanced properties and the elucidation of the underlying mechanisms achieved through the incorporation of ILs are reviewed. Next, specific applications of ILs‐modified PEDOT:PSS relevant to bioelectronic devices are presented. Last, there is a concise summary and a discussion regarding the opportunities and challenges in this exciting field.

Photocatalytic CO2 reduction to high‐value chemicals is an attractive approach to mitigate climate change, but it remains a great challenge to produce a specific product selectively by IR light. Hence, UiO‐66/Co9S8 composite is designed to couple the advantages of metallic photocatalysts and porous CO2 adsorbers for IR‐light‐driven CO2‐to‐CH4 conversion. The metallic nature of Co9S8 endows UiO‐66/Co9S8 with exceptional IR light absorption, while UiO‐66 dramatically enhances its local CO2 concentration, revealed by finite‐element method simulations. As a result, Co9S8 or UiO‐66 alone does not show observable IR‐light photocatalytic activity, whereas UiO‐66/Co9S8 exhibits exceptional activity. The CH4 evolution rate over UiO‐66/Co9S8 reaches 25.7 µmol g−1 h−1 with ca.100% selectivity under IR light irradiation, outperforming most reported catalysts under similar reaction conditions. The X‐ray absorption fine structure spectroscopy spectra verify the presence of two distinct Co sites and confirm the existence of metallic Co─Co bond in Co9S8. Energy diagrams analysis and transient absorption spectra manifest that CO2 reduction mainly occurs on Co9S8 for UiO‐66/Co9S8, while density functional theory calculations demonstrate that high‐electron‐density Co1 sites are the key active sites, possessing lower energy barriers for further protonation of *CO, leading to the ultra‐high selectivity toward CH4.

A hard breakdown phenomenon occurs in the TiN/WOX/Pt device owing to the metallic nature of the WOX layer deposited by pulsed direct current (DC) sputtering. In particular, analog resistive switching (RS) is achieved as the defect states of the naturally occurring TiON layer (oxygen vacancies region) between TiN and TiO2 fluctuate based on the polarity of the bias. Interestingly, the TiN/TiO2/WOX/Pt device displays gradual, bipolar, SET and RESET operations during DC voltage sweep cycling without requiring an electroforming process. Excellent linearity in potentiation and depression is demonstrated via identical pulse trains based on the analog RS behavior. Additionally, the neuromorphic system simulation achieved a pattern‐recognition accuracy of over 95% when conductance is employed as the weight in the neural network. Furthermore, essential synaptic functions, such as spike‐rate‐dependent plasticity (SRDP), spike‐number‐dependent plasticity (SNDP), the transition from short‐term plasticity to long‐term plasticity, “learning‐experience” behaviors, and paired‐pulse facilitation (PPF), are demonstrated to emulate biological synapses for neuromorphic computing applications. Lastly, a reservoir computing system (RC) is implemented using the short‐term memory effect of the TiN/TiO2/WOX/Pt device. Specifically, it is deployed to differentiate all 16 (4‐bit) states using various pulse trains, and a simple algorithm is suggested to implement a low‐power consumption system.

All‐solid‐state lithium metal batteries (ASSLMBs) hold great promise for the development of next‐generation high‐safety, high‐energy‐density lithium batteries, but still face the challenges of lithium dendrite growth and thickness. Herein, the ultrathin PEO‐based composite solid polymer electrolyte (denoted as PAL) supported by a low‐density self‐supporting aramid nanofiber (ANF) aerogel framework is developed. The ANF aerogel obtained by a novel CO2‐assisted induced self‐assembly method has a well‐designed bilayer structure with double cross‐linking degree. Benefiting from the intermolecular interaction between ANFs and PEO, the PAL achieves an ultrathin thickness (20 µm) with excellent thermal stability and mechanical strength. Meanwhile, due to the modulation of ionic pathways by the functionalized ANF, the PAL achieves uniform lithium deposition without dendrites, resulting in stable long cycling (1400 h) for symmetric cells. Consequently, the Li|PAL|LiFePO4 (LFP) cell has excellent long‐term cycling stability (1 C, >700 cycles, Coulombic efficiency > 99.8%) and fast charge/discharge performance (rate, 10 C). More practically, the Li|PAL|LFP cell achieves an energy density of 180 Wh kg−1 due to the ability to match a high‐loading (8 mg cm−2) cathode. Furthermore, the double‐layer Li|PAL|LFP pouch cell demonstrates excellent flexibility and safety in cycling and abuse tests.

Reducing the impedance of a triboelectric nanogenerator (TENG) without power loss is crucial for enhancing its energy conversion efficiency and overall performance. In this paper, a novel signal management structure, based on a newly designed sliding‐mode TENG, aimed at effectively reducing impedance by converting narrow, instantaneous signals into broader ones is presented. This transformation is accomplished by adding a grounded electrode connected to a high‐inductive inductor and fine‐tuning the parasitic capacitance of the dielectric material. Utilizing a highly resistive material like P(VDF–TrFE), a significant improvement in the TENG's performance is achieved, resulting in an increase of output power to 0.352 mW and a decrease in impedance from 3.2 to 0.3 MΩ. This results in a threefold increase in charging speed, which can be attributed to the reduced charge loss and improved matching at lower impedance. Based on these promising findings, the enhanced TENG is successfully connected to power a system for electrochemical CO2 reduction for CO production. This system effectively reduces the required electrochemical reduction potential by ≈15% under real environments.

Crop yields are adversely affected by nitrogen (N) losses in humid subtropical regions. This study was conducted to determine whether N dynamics could be manipulated through planting geometry and fertilizer placement. The effects of irrigation (irrigated and rainfed), row pattern (single‐ and twin‐row), and N placement (surface dribble, one knife, two knives, and control) on corn (Zea mays L.) productivity and N use efficiency were investigated at Leland, Mississippi, on a Bosket very fine sandy loam. The total N rate was split into two equal halves of 128 kg N ha−1 at V2 and V6 growth stages. The effects of row pattern and N placement were consistent between irrigated and rainfed environments. There was no interaction between row pattern and N placement nor did row pattern affect corn productivity or N use efficiency parameters. In 2020, when less than 30 mm of rainfall occurred from the first N application through 2 weeks after the last N application, corn grain yield and agronomic N efficiency were not different among placement methods and averaged 11.1 Mg ha−1 and 20.3 kg grain kg−1 fertilizer N, respectively. However, in 2021, applying N with one knife increased corn grain yield by 7% to 14% compared to the two knives and surface dribble application methods; in that year, 235 mm of rainfall occurred from the first N application through 2 weeks after the last N application. Applying N with one knife appears to consistently improve crop productivity and N use efficiency parameters for both irrigated and rainfed environments.

Common bacterial blight (CBB) is an economically important disease that results in quantitative and qualitative yield reductions across the world. Field experiments were conducted to evaluate the effectiveness of the integration of host resistance, vermicompost (VC) seed soaking, and bactericide foliar application against CBB development, nodulation, and agronomic performances of common bean varieties in southern Ethiopia in 2021 and 2022. Two bean varieties (Remeda [moderately resistant] and Awash‐01 [susceptible]), VC (soaking and non‐soaking), and bactericide spraying (unsprayed, 7‐, 14‐, and 21‐day intervals) were regarded as treatments and factorially arranged in a randomized complete block design with three replications. The combined analysis of variance over years revealed significant (p < 0.05) variations in disease severity, area under disease progress curve (AUDPC), nodule, and agronomic parameters between varieties, VC, bactericide spray intervals, and the interaction of the three factors. Seed soaking with VC and three times foliar bactericide application at the 7‐day interval recorded the lowest terminal disease severity (21.30%) and AUDPC (791.67%‐days) and the highest grain yield (4128.80 kg ha−1), nodule, and other agronomic traits for the variety Remeda over the other treatments. Moreover, the same treatment also obtained the highest net benefit of $2729.88 ha−1 and marginal rate of return of 15.94 over untreated plots of the variety Remeda. Similar trends were observed for the variety Awash‐01. Therefore, the findings indicate that the integration of VC seed soaking, thrice application of bactericide at the 7‐day interval along with the variety Remeda can be employed to curtail the effects of CBB and optimize nodulation and agronomic performances of the crop and is recommended for growers in the study areas.

Nanoparticles can suppress asymmetric precursor support collapse during pyrolysis to create carbon molecular sieve (CMS) membranes. This advance allows elimination of standard sol‐gel support stabilization steps. Here we report a simple but surprisingly important thermal soaking step at 400 °C in the pyrolysis process to obtain high performance CMS membranes. The composite CMS membranes show CO2/CH4 (50 : 50) mixed gas feed with an attractive CO2/CH4 selectivity of 134.2 and CO2 permeance of 71 GPU at 35 °C. Furthermore, a H2/CH4 selectivity of 663 with H2 permeance of 240 GPU was achieved for promising green energy resource‐H2 separation processes.

The development of highly efficient catalysts to address the shuttle effect and sluggish redox kinetics of lithium polysulfides (LiPSs) in lithium‐sulfur batteries (LSBs) remains a formidable challenge. In this study, a series of multi‐site catalytic metal‐organic frameworks (MSC‐MOFs) were elaborated through multimodal molecular engineering to regulate both the reactant diffusion and catalysis processes. MSC‐MOFs were crafted with nanocages featuring collaborative specific adsorption/catalytic interfaces formed by exposed mixed‐valence metal sites and surrounding adsorption sites. This design facilitates internal preconcentration, a coadsorption mechanism, and continuous efficient catalytic conversion toward polysulfides concurrently. Leveraging these attributes, LSBs with an MSC‐MOF‐Ti catalytic interlayer demonstrated a 62 % improvement in discharge capacity and cycling stability. This resulted in achieving a high areal capacity (11.57 mAh cm−2) at a high sulfur loading (9.32 mg cm−2) under lean electrolyte conditions, along with a pouch cell exhibiting an ultra‐high gravimetric energy density of 350.8 Wh kg−1. Lastly, this work introduces a universal strategy for the development of a new class of efficient catalytic MOFs, promoting SRR and suppressing the shuttle effect at the molecular level. The findings shed light on the design of advanced porous catalytic materials for application in high‐energy LSBs.
