La experiencia de la técnica: nihilismo y movilización total en Ernst Jünger
Authors: Soto Carrasco David
Published: July 2022

The article analyses the conception of technique and the critique of Modernity in Ernst Jünger at the crucial moments of the First World War and the Weimar Republic, as paradigmatic manifestations of the historical consummation of nihilism and the decline of the bourgeois world. For Jünger, the experience of the Great War represents the triumph of the technique, which not only would have had a decisive warlike role, but also supposes a total mobilization of society and the formation of a new order. In this sense, the technique is imposed as the metaphysical foundation of an era that is revealed in the figure of the worker, which allows the overcoming of nihilism, through the subsumption of labour in violence. Finally, it is analysed Jünger’s reflections on the partiality and non- currently of Weimar and his proposal of total, nationalist and imperial mobilization.

¿Dónde están las compositoras, directoras y solistas en la programación de las Orquestas sinfónicas españolas? Datos, investigación y propuestas
Authors: Pastor Eixarch Pilar
Published: July 2022

A pesar de los actuales avances en la igualdad de oportunidades para las mujeres en la sociedad, en el sector cultural, especialmente en la música clásica, el proceso es mucho más lento. Seguimos sin escuchar en los conciertos habituales de las orquestas sinfónicas las obras de compositoras, tampoco vemos a las directoras de orquesta dirigiendo y las solistas están mucho menos presentes que los solistas. En el presente artículo se presenta un estudio sobre la presencia de compositoras, directoras, solistas y gestoras en los programas de los conciertos de abono de las orquestas sinfónicas españolas durante la temporada 2018/2019. Los resultados son más bajos de lo esperado por lo que se establecen comparaciones con los obtenidos en otros análisis como el Informe sobre la aplicación de la Ley de Igualdad en el ámbito de la cultura en el marco competencial del Ministerio de Cultura y Deporte y los publicados por l’Observatoire de l’égalité dans la culture et la communication. Finalmente se exponen propuestas de mejora, basadas en las del Informe ministerial y en las desarrolladas desde la Feuille du route 2018-2022.
Viaje a la memoria: recreación y apropiación
Authors: Rodríguez Hernández Rosa María
Published: July 2022

Partimos de la dualidad dada por Maurice Blanchot entre Arte/Cultura, análoga a Olvido/Recuerdo, y tomamos dos metáforas; una, la cultura como metáfora del pasado expuesta por Martin Heidegger -pasado como recreación-. Otra, la metáfora del tiempo como desplazamiento, nos situamos en el viaje y en el retorno. A través de éstas interpretamos el regreso como pasado (secreto), y la partida como “pensamiento fiel”, éste incluye a su vez, recuerdo y olvido, además de un olvidarse. Las obras Maya y Soledad a dos, de la compositora Rosa Mª Rodríguez Hernández, sustentan esta perspectiva.

Prerequisites for taking into account the influence of air exchange in the design of residential districts in the regulatory documentation
Authors: Vdovina Elizaveta Vyacheslavovna
Published: July 2022

Many cities face environmental problems, which are currently receiving a lot of attention. The layout of the city' micro-district corresponding to the regulations can provide the most favorable environmental conditions due to air exchange. The building of the city has been developing for centuries, microdistricts have a layout that was regulated by the law, valid at the times of their construction. The object of research is the processes of air exchange in city districts – on the example of Krasnoyarsk. The method of analysis of scientific sources and standards was used for the study, which allowed determining the chronology of changes in factors affecting air exchange and building blocks. The study includes the solution of the following tasks: analysis of the building regulations affecting air exchange in the neighborhood; to determine the principles of planning a residential neighborhood and establish their compliance with the standards on the example of the city of Krasnoyarsk; to consider the prerequisites for the implementation of an environmental aspect in building codes. For the sake of clarity of the data obtained on the problems of air exchange and the principles of development of microdistricts, the history of the planning structure of the development of Krasnoyarsk is investigated. As a result of the study, a general characteristic of the development of regulatory requirements for the development of microdistricts has been identified and presented. The relevance of the topic is determined by the presence of a problem with the accumulation of harmful substances in residential neighborhoods in Krasnoyarsk. In the current planning methods of development in some residential areas of Krasnoyarsk, this problem cannot be solved due to the increase in height and density of buildings while maintaining the same values of distances between buildings, since the regulatory requirements of insolation do not ensure effective ventilation of the district. According to the results of the study, it was concluded that not all previous standards included effective regulations to ensure the necessary air exchange, or they are completely absent. In these standards, factors affecting effective air exchange (height of buildings, distances between buildings and the angle of the buildings) were determined by other requirements, such as sanitary and fire safety standards, insolation requirements.

Published: July 2022

Quinoa germplasm preserves useful and substantial genetic variation, yet it remains untapped due to a lack of implementation of modern breeding tools. We have integrated field and sequence data to characterize a large diversity panel of quinoa. Whole-genome sequencing of 310 accessions revealed 2.9 million polymorphic high confidence single nucleotide polymorphism (SNP) loci. Highland and Lowland quinoa were clustered into two main groups, with FST divergence of 0.36 and linkage disequilibrium (LD) decay of 6.5 and 49.8 kb, respectively. A genome-wide association study using multi-year phenotyping trials uncovered 600 SNPs stably associated with 17 traits. Two candidate genes are associated with thousand seed weight, and a resistance gene analog is associated with downy mildew resistance. We also identified pleiotropically acting loci for four agronomic traits important for adaptation. This work demonstrates the use of re-sequencing data of an orphan crop, which is partially domesticated to rapidly identify marker-trait association and provides the underpinning elements for genomics-enabled quinoa breeding.
Multi-locus evaluation of gastrointestinal bacterial communities from Zalophus californianus pups in the Gulf of California, México
Authors: Ramirez-Delgado David , Cicala Francesco , Gonzalez-Sanchez Ricardo A. , Avalos-Tellez Rosalia , Solana-Arellano Elena , Licea-Navarro Alexei
Published: July 2022

Background

The gastrointestinal (GI) bacterial communities of sea lions described to date have occasionally revealed large intraspecific variability, which may originate from several factors including different methodological approaches. Indeed, GI bacterial community surveys commonly rely on the use of a single hypervariable region (HR) of 16S rRNA, which may result in misleading structural interpretations and limit comparisons among studies. Here, we considered a multi-locus analysis by targeting six HRs of 16S rRNA with the aims of (i) comprehensively assessing the GI bacterial consortium in rectal samples from Zalophus californianus pups and (ii) elucidating structural variations among the tested HRs. In addition, we evaluated which HRs may be most suitable for identifying intrinsic, structurally related microbiome characteristics, such as geographic variations or functional capabilities.

Methods

We employed a Short MUltiple Regions Framework (SMURF) approach using the Ion 16S™ Metagenomic Kit. This kit provides different proprietary primers designed to target six HRs of the 16S rRNA gene. To date, the only analytical pipeline available for this kit is the Ion Reporter™ Software of Thermo Fisher Scientific. Therefore, we propose an in-house pipeline to use with open-access tools, such as QIIME2 and PICRUSt 2, in downstream bioinformatic analyses.

Results

As hypothesized, distinctive bacterial community profiles were observed for each analyzed HR. A higher number of bacterial taxa were detected with the V3 and V6–V7 regions. Conversely, the V8 and V9 regions were less informative, as we detected a lower number of taxa. The synergistic information of these HRs suggests that the GI microbiota of Zalophus californianus pups is predominated by five bacterial phyla: Proteobacteria (~50%), Bacteroidetes (~20%), Firmicutes (~18%), Fusobacteria (~7%), and Epsilonbacteraeota (~4%). Notably, our results differ at times from previously reported abundance profiles, which may promote re-evaluations of the GI bacterial compositions in sea lions and other pinniped species that have been reported to date. Moreover, consistent geographic differences were observed only with the V3, V4, and V6–V7 regions. In addition, these HRs also presented higher numbers of predicted molecular pathways, although no significant functional changes were apparent. Together, our results suggests that multi-locus analysis should be encouraged in GI microbial surveys, as single-locus approaches may result in misleading structural results that hamper the identification of structurally related microbiome features.

Authors: Dokwal Sumit , Arya Amit , Sachdeva Ashuma , Rathi Manisha , Sachdeva Sumit , Prashant Praveen , Arora Varun , Bhutani Jaikrit
Published: July 2022

Introduction: Myopia is most common refractive error leading to visual dysfunctions worldwide. Oxygen deficit due to environmental stress leads to increase in anaerobic glycolysis which results in lactate production. Increase in Reactive Oxygen Species (ROS) and inability of defense system to eliminate them is also responsible for alteration of regulatory pathways. The patient with elevated lactate levels are at significant risk of morbidity and hence, require a prompt treatment. Aim: To estimate and study the lactate levels in tear in various degree of myopia. Materials and Methods: This case-control study was conducted in tertiary care center, Pt. B.D. Sharma PGIMS, Rohtak, Haryana, India. Twenty five patients each with low, medium, high myopia, age and sex matched healthy controls (i.e, Group 1-4). Diagnosis was established with help of detailed history, clinical and ocular examination. Lactate levels were estimated in tear samples by enzymatic method on autoanalyzer within 30 minutes of collection. Independent Student’s t-test was used to determine the significance between myopia and controls. Results: Out of total 100 subjects, 68% were males and 32% were females. The mean±SD age was 24.56±6.35, 24.12±5.45, and 23.24±5.17, 21.69±3.95 in the Group 1, Group 2, Group 3 and Group 4 respectively in the control group, group with low, medium and high myopia respectively which was statistically not significant. The results of this study showed that lactate levels in tears were significantly higher (p-value=0.013) in myopia patients as compared to controls (1.34±0.46 versus 1.06±0.50). Additionally, the lactate levels increased with the progression of degree of myopia. Conclusion: Increase in the level of lactate in tear was directly proportional to the degree of myopia. Tear lactate levels can be used as a non invasive method to study oxidative stress in individuals. Further studies with more oxidative markers in tears can also be compared with blood values in larger groups of patients with long-term follow-up to validate the finding.

Authors: Gupta Uttara , Namdeo Pooja , Patel Neelam
Published: July 2022

Introduction: Doppler ultrasonography, by comparing systolic and diastolic waveforms helps in assessment of uteroplacental circulation. Since preeclampsia has ethnic and geographical variations, it is important to understand the prediction modalities in various populations. Aim: To investigate the role of elevated Pulsatility Index (PI) and presence of diastolic notch using uterine artery doppler in early pregnancy in predicting development of preeclampsia among pregnant women. Materials and Methods: A prospective cohort study was conducted on pregnant females visiting the antenatal clinic or Outpatient Department or admitted in the Department of Obstetrics and Gynaecology at People's College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India, from November 2019 to October 2021. All cases were subjected to uterine artery doppler study, between 11-14 weeks of pregnancy, to note pulsatility index and diastolic notch. All the participants were then screened periodically during their antenatal visits for development of features of preeclampsia and were followed-up monthly upto 20 weeks, every 15 days upto 32 weeks and then weekly till delivery. Pregnancy outcome were measured in terms of presence or absence of preeclampsia. Data was compiled using Microsoft Excel and analysed using Statistical Package for Social Sciences (SPSS) IBM software version 20.0. Categorical data was expressed as frequency and proportions whereas continuous data was expressed as mean and standard deviation. Results: The present study was conducted on a total of 116 cases with the mean age of 26.75±4.31 years. Out of 116 cases, 26 cases developed preeclampsia. Diastolic notch was present in 17 cases (65.4%) patients with preeclampsia and 23 cases (25.6%) non preeclampsia patients. Pulsatility index of more than 1.71 was noted in 14 cases (53.8%) cases with preeclampsia where as 87 cases (96.7%) with non preeclampsia had pulsatility index of less than 1.71. The specificity of diastolic notch 74.4% where as that of pulsatility Index was 96.7 % and the diagnostic accuracy of diastolic notch 72.4% where as that of pulsatility index was 87.1%. Conclusion: Uterine artery doppler is a promising tool for predicting development of preeclampsia by analysing both PI as well as diastolic notch in uterine artery. Doppler had high overall diagnostic accuracy for preeclampsia.

Published: July 2022

Farmer Producer Organizations (FPOs) as the business entities need to be aware of all the technologies and ideally utilize them to earn profits for the company. Electronic commerce, sometimes known as e-commerce, is one example of such technology. E-commerce refers to any transaction that takes place over the internet. As a result, FPOs must learn how to use e-commerce platforms for a variety of agricultural activities such as bulk trading of produce, purchasing inputs, accessing market information or crop management procedures. This study was conducted to assess the awareness level of members of FPOs on e-commerce platforms related to agriculture. A sample of 146 farmers was selected through multi-stage proportionate sampling from four villages with the highest number of farmers registered under FPOs from Donakonda mandal of the Prakasam district of Andhra Pradesh. Data collection was done through a well-structured interview schedule. Statistical tools such as mean, standard deviation, frequency and percentage were used to analyze the result. Study findings indicate that respondents had a medium level of awareness about e-commerce in agriculture.

Published: July 2022

The pineal gland is a small endocrine gland in the brain that regulates the circadian rhythm in humans. It is responsible for melatonin production, also produced by parenchymal and glial cells. Pineal region tumors account for 3–11% of pediatric brain tumors, and 1% of adult brain tumors according to World health Organization (WHO). These tumors arise from the germ cells, pineal cells, and adjacent structures. It is fundamental for medical knowledge (clinical and laboratory) to differentiate and identify the various types of pineal gland tumors and thus facilitate accurate diagnosis with crafted therapeutic management of the pathology accompanying its incidence. There exist different histological subtypes of pineal body tumors and various management options like surgery, chemotherapy and radiotherapy. The review article is a student’s project on integrated learning, aiming at understanding the pathophysiology of the rare pineal body tumor.

Published: July 2022

This study summarizes the importance of melatonin in different plants and fungi. In this review, we discussed the biosynthetic pathway of melatonin, its metabolites, and its oxidative reduction. Melatonin is a molecule derived from tryptophan, with pleiotropic activity. It is present in nearly every organism. Its synthetic course depends on the organism in which it resides. The tryptophan to the melatonin pathway, for example, varies in plants and animals. It is thought that the synthetic mechanism for melatonin was inherited in eukaryotes from bacteria caused by endosymbiosis. Nevertheless, the synthetic pathways of melatonin in microorganisms are unknown. The metabolism of melatonin is exceptionally complex with these enzymatic processes developed out of cytochrome C. As well as the enzymatic degradation, melatonin is metabolized by interactive pseudoenzymes and free radicals processes.
Long Term Impact of Fertilization and Intensive Cropping on Maize Yield and Soil Nutrient Availability under Sandy Clay Loam Soil (Inceptisol)
Authors: Manimaran G. , Jayanthi D. , Janaki P. , Amirtham D. , Gokila B.
Published: July 2022

A field experiment was conducted to evaluate the impact of crop productivity and soil nutrient availability under continuous cropping and fertilization. A single nutrient application or omission of nutrient or mineral fertilizer alone can deteriorate the soil nutrient availability and yield in long run. The result revealed that soil pH and EC have not changed substantially even after the repeated application of fertilizers over five decades. The use of balanced fertilizers either alone or integrated with organic manure (FYM) has significantly increased the grain and straw yield of maize. The yield increment of maize was observed 13.9 percent higher than 100% NPK and 18.3 percent higher than without the addition of S (S free). Balanced fertilization can improve the soil nutrients (N, P, K & S) and soil organic carbon instead addition of FYM @ 10 t ha-1 could increase the SOC and soil nutrients in long run in a sustainable manner. Concerning nitrogen, single nutrient (N alone) plots received low available nutrients and yield also it’s deteriorated the soil nutrients over long period. A build-up of available soil P and S was observed due to its continuous addition through fertilizer but soil K has reduced because of intensive cropping and high-yielding cultivars. Hence, for sustainable  roduction, application of a recommended dose of mineral fertilization (100% NPK) along with FYM @ 10 t ha-1 may be used to achieve a higher yield, stable nutrient balance and soil quality over decades.
Evaluating the Degradation Effect of Bacterial Consortium from the Feces of Bos tarus and Fecal Matter on Crude Oil Polluted Soil
Authors: Owarieta Urhibo, Voke , Eunice A. Odesiri-Eruteyan,
Published: July 2022

Aim: This study evaluated the effect of degradation of bacterial isolates from the feces of Bos tarus and fecal matter on crude oil polluted soil in a laboratory scale.

Study Design: This study covered the isolation of bacterial consortium from the fecal matter of Bos tarus obtained from Giriki Farms located at Gariki barn Uti, Delta State, Nigeria used to treat soil sample spiked with crude oil obtained from the Warri Refining and Petrochemical Company (WRPC)

Place and Duration of Study: The study was conducted in the Environmental Science laboratory, Federal University of Petroleum Resources, Effurun, Delta State, Nigeria. The research lasted for four months.

Methodology: Hydrocarbon utilizing bacteria consortium was isolated from the dung of Bos tarus using a carbon free medium employing pour plate/vapor phase techniques. The identified consortiums were screened to select the fastest degrader of hydrocarbons by 2,6-dichlorophenolindophenol (DCPIP). The best fit consortium was subjected to purification and identification of its bacterial make up using standard microbiological procedures. The selected consortium was standardized after washing to 0.1 optical density at 600nm and used to treat soil spiked with crude oil alone and with fecal matter. The degradation effect of the residual crude oil was determined by Gas chromatography.

Results: Results showed that isolates were capable and effective in degrading crude  oil with performance enhanced in crude oil polluted soil with bacterial consortium andfecal matter (90.29%) and 78.00% in polluted soil with only bacterial isolates. This clearly  points to the roles of elemental constituents of the fecal matter acting as a catalyst and bio-stimulant to hasten the rate of degradation of crude oil although not undermining the role of microorganisms.

Conclusion: The study revealed that microorganisms from the waste of Bos tarus are capable of degrading short and long chain hydrocarbons present in crude oil and the degradation process is enhanced if the ecological niche from which the isolates are drawn is maintained.

Published: July 2022

The menace of drug resistant pathogens is increasing and their level of evading conventional antimicrobials is rising. It is therefore important to discover new antimicrobials to counter the current challenges. Our preliminary investigation identified Bacillus subtilis subsp. subtilis 168 isolated from soil sample sourced from a river bank in Abuja, Nigeria, as the most potent antibiotic-producing bacteria among the other identified producers. The current study screened for the antimicrobial activity of the extract and fractions of the isolate by broth microdilution method. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and the ratio of the MBC/MIC were determined. All the tested pathogens were susceptible to the ethyl-acetate extract (MIC between 28.70 mg/ml and 57.40 mg/ml). The extract displayed bactericidal activity against all tested pathogens (MBC/MIC between 1.00 and 2.00) while Proteus mirabilis was least susceptible. The extract was purified by vacuum liquid chromatography and the fractions challenged with pathogenic strains.  The fraction E was the most potent (MIC between 0.09 mg/ml and 0.75 mg/ml) and also bactericidal against all the test microbes (MBC/MIC between 2.00 and 2.11).  GC-MS analysis of the purified sub fraction obtained from fraction E identified 13 compounds with different Retention time and peak areas.  Among these were three major compounds which include: (i) bis(2-ethylhexyl) phthalate (ii) 1,4-epoxynaphthalene-1(2H)-methanol, 4,5,7-tris(1,1-dimethylethyl)-3,4-dihydro- (iii) D:B-Friedo-B':A'-neogammacer-5-en-3-ol, (3.beta.)-.  Our findings suggest that Bacillus subtilis subsp. subtilis 168 isolated locally could serve as a valuable source of lead compounds for pharmaceutical and biotechnological purposes.

Neural Regulation of Cancer: Cancer‐Induced Remodeling of the Central Nervous System
Authors: Krishna Saritha , Hervey‐Jumper Shawn L.
Published: July 2022

In recent years, there have been significant advances in understanding the neuronal influence on the biology of solid tumors such as prostate, pancreatic, gastric, and brain cancers. An increasing amount of experimental evidence across multiple tumor types strongly suggests the existence of bidirectional crosstalk between cancer cells and the neural microenvironment. However, unlike cancers affecting many solid organs, brain tumors, namely gliomas, can synaptically integrate into neural circuits and thus can exert a greater potential to induce dynamic remodeling of functional circuits resulting in long‐lasting behavioral changes. The first part of the review describes dynamic changes in language, sensory, and motor networks following glioma development and presents evidence focused on how different patterns of glioma‐induced cortical reorganization may predict the degree and time course of functional recovery in brain tumor patients. The second part focuses on the network and cellular‐level mechanisms underlying glioma‐induced cerebral reorganization. Finally, oncological and clinical factors influencing glioma‐induced network remodeling in glioma patients are reviewed.

Impedance spectroscopy reveals electronically pseudo‐intrinsic conductivities for a broad range of different dopants (Fe, Al, Ni) and partly high dopant concentrations up to several percent. Using inductively‐coupled plasma optical emission spectroscopy and reciprocal space mapping, a severe Sr deficiency is found and positron annihilation lifetime spectroscopy revealed Sr vacancies as predominant point defects. From synchrotron‐based X‐ray standing wave and X‐ray absorption spectroscopy measurements, a change in site occupation is deduced for Fe‐doped SrTiO3 films, accompanied by a change in the dopant type. Based on these experiments, a model is deduced, which explains the almost ubiquitous pseudo‐intrinsic conductivity of these films. Sr deficiency is suggested as key driver by introducing Sr vacancies and causing site changes (FeSr and TiSr) to accommodate nonstoichiometry. Sr vacancies act as mid‐gap acceptor states, pinning the Fermi level, provided that additional donor states (most probably ) are present. Defect chemical modeling revealed that such a Fermi level pinning also causes a self‐limitation of the Ti site change and leads to a very robust pseudo‐intrinsic situation, irrespective of Sr/Ti ratios and doping.

Single‐atom catalysts (SACs) are widely investigated in Fenton‐like reactions for environmental remediation, wherein their catalytic performance can be further improved by coordination structure modulation, but the relevant report is rare. Herein, a series of atomically dispersed cobalt catalysts with diverse coordination numbers (denoted as CoNx, x represents nitrogen coordination number) are synthesized and their peroxymonosulfate (PMS) conversion performance is explored. The catalytic specific activity of CoNx is found to be dependent on coordination number of single atomic Co sites, where the lowest‐coordinated CoN2 catalyst exhibits the highest specific activity in PMS activation, followed by under‐coordinated CoN3 and normal CoN4. Experimental and theoretical results reveal that reducing coordination number can increase the electron density of single Co atom in CoNx, which governs the Fenton‐like performance of CoNx catalysts. Specifically, the entire Co–pyridinic NC motif serves as active centers for PMS conversion, where the single Co atom, and pyridinic N‐bonded C atoms along with nitrogen vacancy neighboring the unsaturated Co–pyridinic N2 moiety account for PMS reduction and oxidation toward radical and singlet oxygen (1O2) generation, respectively. These findings provide a useful avenue to coordination number regulation of SACs for environmental applications.

Establishing local built‐in electric field of 2D semiconductors is one of the promising strategies to regulate the oriented charge delivery to active centers for enhancing photocatalytic performance. Herein, a novel heptamolybdate polyanions‐intercalated porous g‐C3N4 ([Mo7O24]6−‐pCN) catalyst with integrating highly desirable visible‐light photocatalytic features is reported. After intercalation, the apparent reaction rate constants (kapp) of [Mo7O24]6−‐pCN for bisphenol A (BPA) and 4‐chlorophenol (4‐CP) photodegradation are remarkably enhanced, which are 9.0 and 6.4 times faster than those of pCN, respectively. Analogously, the kapp values of [Mo7O24]6–‐CN for BPA and 4‐CP removal are also improved by contrast with CN. The experimental results and density functional theory calculations indicate that a local built‐in electric field is formed in [Mo7O24]6−‐pCN with a polarization direction from aromatic rings of g‐C3N4 to the inserted [Mo7O24]6− clusters. Driven by the electric field, photogenerated carriers can be efficiently separated for better reactive oxidative species (ROSs) production. These O atoms are also proved as adsorption sites for phenols, greatly reducing the migration distance of ROSs and thus improving photocatalytic performances. This work offers a reliable strategy to construct local built‐in electric field via polyoxometalates intercalation for effective solar energy conversion and phenolic wastewater remediation.

Suppressing losses that originate from domain‐wall motion in ferroelectrics is essential to high‐power piezoelectric applications. Conventional models of the hardening effect assume that domain‐wall mobility can be greatly impeded due to the pinning of lattice defects or charge carriers. However, these models cannot satisfactorily explain the dramatical increase of mechanical quality factor from ≈500 to ≈2500 in ferroelectric sodium lithium niobate induced by annealing. In the present study, the specific hardening effect is systematically investigated from multiple perspectives, including kinetics, phase transition, and domain configuration. The enhancement is proposed to be associated with the thermally induced domain reconfiguration at the nanoscale approaching the ferroelectric‐paraelectric phase transition temperature. The comprehensive experimental observations reveal a unique mechanism of the hardening effect in ferroelectrics, shedding light on the enhancement of the performance of high‐power piezoelectric applications.

Bipolar junction transistors (BJTs), the basic building blocks of integrated circuits, are deployed to control switching applications and logic operations. However, as the thickness of a conventional BJT device approaches a few atoms, its performance decreases substantially. The stacking of atomically thin 2D semiconductor materials is advantageous for manufacturing atomically thin BJT devices owing to the high carrier density of electrons and holes. Here, an atomically thin n–p–n BJT device composed of heavily doped molybdenum ditelluride (n‐MoTe2) and germanium selenide (p‐GeSe) sheets stacked over each other by van der Waals interactions is reported. In a common‐emitter configuration, MoTe2/GeSe/MoTe2 BJT devices exhibit a considerably high current gain (β  =  Ic /Ib = 29.3) at Vbe = 2.5 V. The MoTe2/GeSe/MoTe2 BJT device is employed to detect streptavidin biomolecules as analytes within <10 s. The real‐time response of the functionalized BJT device is examined at various concentrations of streptavidin biomolecules ranging from 250 to 5 pm. Such vdW BJT devices can trigger the development of state‐of‐the‐art electronic devices that can be used as biosensors to detect the various kinds of target DNA and proteins like spike protein of Covid‐19.

Exploring efficient energy systems with integrated energy harvesting and storage toward sustainable power sources is an extremely promising solution for alleviating the energy crisis but nevertheless remains an arduous challenge. Here, a high‐efficient self‐charging power system (SCPS) by integrating solid‐state asymmetric supercapacitors device (SASD) and rotational triboelectric nanogenerator (RTENG) to achieve efficient energy harvesting and storage is reported. Dual redox active sites Ni2P/NiSe2 heterostructure is homogeneously inlaid on N‐C (N‐C@Ni2P/NiSe2) via an in situ phosphoselenization, which achieves the maximum exposure of active sites and prevents the aggregation of nanoparticles. The ingeniously designed N‐C@Ni2P/NiSe2 heterostructure features high activity dual redox sites, well‐defined heterointerface, and stable superhighway conductive support, which facilitates high electrochemical reaction efficiency, accelerated reaction kinetics, and enhanced electrochemical stability, thus achieving high capacitance and excellent stability. Meanwhile, the SASD delivers high energy density and long lifespan. Furthermore, the RTENG exhibits high output performance, enabling efficient energy harvesting. The SCPS can reach a voltage of 3.8 V within 40 s, and continuously power electronics. It is believed that the proposed survey based on the design and integration of dual redox active sites heterostructure will offer a new prospect for next‐generation sustainable power sources.

Carbon‐based inorganic perovskite solar cells (C‐PSCs) have attracted intensive attention owing to their low cost and superior thermal stability. However, the bulk defects in perovskites and interfacial energy level mismatch seriously undermine their performance. To overcome these issues, a multifunctional dual‐interface engineering is proposed with a focus on low‐temperature CsPbI2Br C‐PSCs, where the potassium trifluoroacetate (KTFA) and the 4‐trifluorophenyl methylammonium bromide (CF3PMABr) are introduced beneath and on top of the perovskite layer, respectively. It is found that TFA‐ ions locate at the SnO2/CsPbI2Br interface, whereas a small amount of K+ ions diffuse into perovskite lattice to participate in nucleation and crystallization, resulting in more favored interfacial energy level alignment, improved film quality, passivated interfacial defects, released interfacial strain, as well as suppressed charge recombination and ion migration. Meanwhile, the CF3PMABr passivates I/Br vacancies and forms 2D perovskite capping layer to facilitate hole extraction at the CsPbI2Br/carbon interface. As a result, a remarkable power conversion efficiency (PCE) of 14.05% with an open‐circuit voltage of 1.273 V is achieved. To the best of the authors’ knowledge, it is currently the highest PCE reported for low‐temperature CsPbI2Br C‐PSCs. Furthermore, the nonencapsulated device exhibits improved moisture, thermal, and illumination stability in ambient air.
