Published: July 2022

Transient tachynpea of the newborn, which is a self-limiting condition, in some cases requires invasive respiratory support. This study aimed to investigate the influence of gestational age and mode of delivery on oxygen therapy, and the occurence of complications. This retrospective study covered data about children diagnosed with transient tachypnea who were born during the period of one year. The duration of oxygen therapy and the assessment of complications were analyzed according to the mode of delivery and gestational age. In 77,3% of cases transient tachypnea was well-managed with the use of oxygen therapy in incubator. In relation to the mode of delivery and gestational age, no significant differences in the duration of different oxygen therapy types were observed. Two newborns developed persistent pulmonary hypertension, and one newborn had pneumothorax. Invasive respiratory support is not frequently used in transient tachypnea. Persistent pulmonary hypertension and air leak syndrome are possible but very rare complications of this condition.

Alterations in the serum of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) size and subclass contribute to the atherogenesis in coronary artery disease in diabetic patients. The purpose of this study is to evaluate the effect of metabolic parameters on LDL and HDL size and subclasses in adolescents with type 1 diabetes. The cross-sectional study included 43 adolescents (23 females, 20 males) with type 1 diabetes of mean age 15.09±1.94 years, with mean disease duration of 5.86 ± 3.08 years. LDL and HDL particles were separated by polyacrylamide gradient gel electrophoresis, while serum lipid parameters were determined by routine laboratory methods. Patients with inadequate metabolic control (HbA1c ≥ 7.5%) had a higher mean value of triglycerides (TG) (p = 0.041), higher proportions of small, dense LDL particles (p = 0.045), higher proportions of LDL IIA subclasses (p=0.03) and smaller LDL diameter (p = 0.02) and HDL diameter (p = 0.04) than patients with optimal metabolic control (HbA1c < 7.5%). Higher HbA1c and higher TG levels were statistically significantly related to small, dense LDL (r=0.341, p=0.025; r= 0.394, p= 0.009) and HDL particles (r=0.684, p=0.000; r=0.421, p=0.005). Predictors of small, dense LDL and HDL particles, which contribute to atherogenesis, were high HbA1c (HR = 1.52, 95% CI: 0.97-2.40; HR 3.87, 95% CI: 2.11-7.10) and elevated TG (HR= 1.10, 95% CI: 1.00-1.20; HR 1.85, 95% CI: 1.07-3.21). Diabetic adolescents require particular attention in order to minimize factors such as high HbA1c and elevated TGs in the development of future cardiovascular events.

Published: July 2022

A well-balanced diet is an important factor in the promotion and maintenance of good health throughout one's life. The role of a diet as a determinant of chronic non-communicable diseases is well established and it occupies a prominent position in prevention. The burden of chronic diseases is rapidly increasing worldwide. Namely, chronic non-communicable diseases are the leading cause of death worldwide. Preterm mortality in people under 70 accounts for over 40% of the total of 38 million deaths due to chronic non-communicable diseases. Obesity, metabolic syndrome, and diabetes mellitus are also showing worrying trends, not only because they already affect a large part of the population, but also because they have started to occur earlier in life. Thus, the metabolic syndrome is a cluster of more or less related metabolic and cardiovascular derangements including visceral obesity, insulin resistance, dyslipidemia, hypertension and glucose intolerance. This syndrome is characterized by a primary cellular defect in insulin action due to disorders in insulin signal transduction (insulin is unable to adequately achieve its biological effects). Under these conditions, insulin resistance, in combination with hyperinsulinemia causes numerous metabolic and cardiovascular disorders, which are leading causes of morbidity and mortality worldwide. From the pathophysiological point of view, a diet rich in carbohydrates and saturated fats significantly contributes to the development of many chronic diseases (diabetes mellitus type 2, hypertension, accelerated atherosclerosis and its cardiovascular and cerebrovascular complications, nonalcoholic fatty liver disease, polycystic ovary syndrome, and some malignant diseases - breast cancer, etc.). In this review, we provide an overview of recent literature data and practical knowledge related to an unbalanced diet as a cardiometabolic risk factor. Further investigations in the field of molecular prevention may contribute to the development of new biomarkers, or help the setting of strategies for molecular prevention of chronic non-communicable diseases. In other words, they represent the directive for applying nutrigenomics to population sciences.

Authors: Živanović Vladimir , Vitomir Jelena
Published: July 2022

New technologies have a significant role in modern financial markets. The application of new technologies, application and software solutions has enabled financial institutions and individual and institutional investors to use mathematical-statistical and econometric models, which are based on analysis and evaluation of investment portfolios, financial risk assessment and extrapolation, as well as predictability related to cyclical economic trends, which are directly reflected in the investment portfolio. Due to the impact of the financial crisis, and especially due to global negative economic trends caused by the COVID-19 pandemic, alternative forms of financial assets that are directly created by the application of new technologies are becoming increasingly important in the international financial market. These alternative forms of financial assets are presented as cryptocurrencies. Bitcoin is the first cryptocurrency in the global financial market, and Ethereum is the second cryptocurrency in terms of market turnover. In this regard, arises the question: "Do these two leading cryptocurrencies have a significant impact on the modern financial market, as well as on the decision of individual and institutional investors regarding a different structure of the investment portfolio?" Restructuring the investment portfolio by including cryptocurrencies, aims to achieve portfolio diversification in order to better manage market and financial risks. This paper will analyze the impact of cryptocurrencies, their volatility, turnover volume and the possibility of using them as alternative financial assets of an optimal investment portfolio.
Theoretical and empirical aspects of the relationship between morality and economy
Authors: Đorić Žarko
Published: July 2022

That economics is devoid of any moral, ideological, or theological philosophy is a widespread view among major economists in recent times. In relation to issues of a moral nature, modern economics is focused on key postulates such as rational calculation, scientific neutrality and basic material goals. In connection with the aforementioned gap, which is deepening, the primary goal of the paper is to point out the need to establish a new alliance between economics and morality (ethics) as a specific value criterion, all in order to better understand the complex nature of human reality and contributing to more effective and constructive solutions to economic problems. In doing so, one bears in mind the fact that attempts to portray the economy as morally neutral have largely ended in failure, or with little success.

Published: July 2022

This paper aims to examine Serbian female entrepreneurs' performance related to digital competences based on real-life scenario questions. The research was conducted on a sample of 114 female entrepreneurs. The method used for collecting data was an online survey (Google form). The survey questions were based on Digital Competence Framework (DigComp) focusing on the first two areas, "Information and data literacy" and "Communication and collaboration". The results showed that the female entrepreneurs in Serbia achieved better performance (i.e., answered the questions correctly) in the area "Information and data literacy" especially in the segment "Browsing, searching, and filtering data, information and digital content". On the other side, lower performance of Serbian female entrepreneurs was achieved in the area "Communication and collaboration", where nine questions from thirteen were not answered correctly. Segments "Engaging in citizenship through digital technologies", "Collaborating through digital technologies" and "Netiquette" were identified as the most problematic because there was no correct answer. The authors can conclude that skills incorporated in the segments of the second area need to be improved and boosted to be in line with market demands.

Different ways for visualization of data obtained from an arduino uno microcontroller board
Authors: Pavlov-Kagadejev Marijana
Published: July 2022

Arduino microcontroller platforms are frequently in use in the last few years. The reason is their simplicity, low cost, and availability of a large number of ready-made solutions on the Internet. The Arduino Integrated Development Environment itself has a Serial Monitor and Serial Plotter tools for data presentation. The Serial Monitor displays the textual and numeric values of the data obtained through the serial port. By using the Serial Plotter, measurement results from the Arduino serial port can be seen in the form of Real-Time diagrams. The deficiency of such a way of data visualization is that it does not provide many opportunities for change and adaptation to the user needs. This paper presents examples of several different programming environments which provide the good opportunities for presentation the results generated by the Arduino boards. Some hardware modules used to display data from the Arduino boards are also described in this paper.

Authors: Domínguez Gurría Miguel Alberto , SZWEDOWICZ WASIK DARIUSZ , MARTINEZ RAYON ELADIO , ESTRADA BARBOSA QUIRINO
Published: July 2022

This paper presents an experimental and numerical study that allows to evaluate the dissipation of impact energy, proposing a friction damper with the use of layers (LFD) for impact energy dissipation. The study is carried out on a macro scale of contact between the layers and friction elements. The effects of displacement and applied speed are experimentally analyzed. Numerically, the FEM analyses the effects of the preload and the material of the friction layers on the hysteretic behavior of the LFD. The energy dissipation in a cycle increases with respect to the applied displacement. The operating range of the LFD is variable, because the stiffness of the system increases with respect to the applied displacement. The preload applied to the damper varies with respect to the displacement applied. A theoretical approach is established to estimate the energy dissipation of the system with previously defined parameters or, to define the geometry and material of the damper elements for an estimated energy range.

Published: July 2022

Beef price is relatively expensive, which makes this commodity vulnerable to be counterfeited. The development of rapid, cheap and robust analytical methods for meats authentication has therefore become increasingly important. In this study, colorimetric and digital image analysis methods were used to characterize and classify four types of meat (beef, buffalo, pork, wild boar) and two muscle types from each sample (Semitendinosus and Vastus lateralis). Multivariate data analysis (PCA and OPLS-DA) was used to observe classification pattern among species using different color parameters data obtained from meat chromameter and digital image measurement. The results showed that PCA and OPLS-DA successfully classified meat from different species and different muscle type based on color, both in chromameter and in image analysis. It was shown that pork had the highest lightness level, and was the most different among the four types of meat tested. Beef was predominated by yellowish color, while buffalo meat had the highest reddish color level.  Semitendinosus and Vastus lateralis muscles had different color intensity where Vastus lateralis exhibited darker color intensity. This study showed that meat color analysis using chromameter and imaging techniques can be used as cheap and quick tools to discriminate meats form different species and different muscles type.
Life history predicts global population responses to the weather in terrestrial mammals
Authors: Jackson John , Le Coeur Christie , Jones Owen
Published: July 2022

With the looming threat of abrupt ecological disruption due to a changing climate, predicting which species are most vulnerable to environmental change is critical. The life-history of a species is an evolved response to its environmental context, and therefore a promising candidate for explaining differences in climate-change responses. However, we need broad empirical assessments from across the world's ecosystems to explore the link between life history and climate-change responses. Here, we use long-term abundance records from 157 species of terrestrial mammals and a two-step Bayesian meta-regression framework to investigate the link between annual weather anomalies, population growth rates, and species-level life history. Overall, we found no directional effect of temperature or precipitation anomalies or variance on annual population growth rates. Furthermore, population responses to weather anomalies were not predicted by phylogenetic covariance, and instead there was more variability in weather responses for populations within a species. Crucially, however, long-lived mammals with smaller litter sizes had smaller absolute population responses to weather anomalies compared with their shorter living counterparts with larger litters. These results highlight the role of species-level life history in driving responses to the environment.
Inner membrane complex proteomics reveals a palmitoylation regulation critical for intraerythrocytic development of malaria parasite

Published: July 2022

Malaria is caused by infection of the erythrocytes by the parasites Plasmodium. Inside the erythrocytes, the parasites multiply via schizogony, an unconventional cell division mode. The inner membrane complex (IMC), an organelle located beneath the parasite plasma membrane, serving as the platform for protein anchorage, is essential for schizogony. So far, the complete repertoire of IMC proteins and their localization determinants remain unclear. Here we used biotin ligase (TurboID)-based proximity labeling to compile the proteome of the schizont IMC of the rodent malaria parasite Plasmodium yoelii. In total, 300 TurboID-interacting proteins were identified. 18 of 21 selected candidates were confirmed to localize in the IMC, indicating good reliability. In light of the existing palmitome of Plasmodium falciparum, 83 proteins of the P. yoelii IMC proteome are potentially palmitoylated. We further identified DHHC2 as the major resident palmitoyl-acyl-transferase of the IMC. Depletion of DHHC2 led to defective schizont segmentation and growth arrest both in vitro and in vivo. DHHC2 was found to palmitoylate two critical IMC proteins CDPK1 and GAP45 for their IMC localization. In summary, this study reports an inventory of new IMC proteins and demonstrates a central role of DHHC2 in governing the IMC localization of proteins during the schizont development.

The presynaptic protein α-synuclein (αSyn) has been suggested to be involved in the pathogenesis of Parkinson’s disease (PD). In PD, the amygdala is prone to develop insoluble αSyn aggregates, and it has been suggested that circuit dysfunction involving the amygdala contributes to the psychiatric symptoms. Yet, how αSyn aggregates affect amygdala function is unknown. In this study, we examined αSyn in glutamatergic axon terminals and the impact of its aggregation on glutamatergic transmission in the basolateral amygdala (BLA). We found that αSyn is primarily present in the vesicular glutamate transporter 1-expressing (vGluT1+) terminals in the mouse BLA, which is consistent with higher levels of αSyn expression in vGluT1+ glutamatergic neurons in the cerebral cortex relative to the vGluT2+ glutamatergic neurons in the thalamus. We found that αSyn aggregation selectively decreased the cortico-BLA, but not the thalamo-BLA, transmission; and that cortico-BLA synapses displayed enhanced short-term depression upon repetitive stimulation. In addition, using confocal microscopy, we found that vGluT1+ axon terminals exhibited decreased levels of soluble αSyn, which suggests that lower levels of soluble αSyn might underlie the enhanced short-term depression of cortico-BLA synapses. In agreement with this idea, we found that cortico-BLA synaptic depression was also enhanced in αSyn knockout mice. In conclusion, both basal and dynamic cortico-BLA transmission were disrupted by abnormal aggregation of αSyn and these changes might be relevant to the perturbed cortical control of the amygdala that has been suggested to play a role in psychiatric symptoms in PD.
Conformational fingerprinting of allosteric modulators in metabotropic glutamate receptor 2
Authors: Liauw Brandon Wey-Hung , Foroutan Arash , Schamber Michael R , Lu Weifeng , Samareh Afsari Hamid , Vafabakhsh Reza
Published: July 2022

Activation of G protein-coupled receptors (GPCRs) is an allosteric process. It involves conformational coupling between the orthosteric ligand binding site and the G protein binding site. Factors that bind at non-cognate ligand binding sites to alter the allosteric activation process are classified as allosteric modulators and represent a promising class of therapeutics with distinct modes of binding and action. For many receptors, how modulation of signaling is represented at the structural level is unclear. Here, we developed fluorescence resonance energy transfer (FRET) sensors to quantify receptor modulation at each of the three structural domains of metabotropic glutamate receptor 2 (mGluR2). We identified the conformational fingerprint for several allosteric modulators in live cells. This approach enabled us to derive a receptor-centric representation of allosteric modulation and to correlate structural modulation to the standard signaling modulation metrics. Single-molecule FRET analysis revealed that a NAM (egative allosteric modulator) increases the occupancy of one of the intermediate states while a positive allosteric modulator increases the occupancy of the active state. Moreover, we found that the effect of allosteric modulators on the receptor dynamics is complex and depend on the orthosteric ligand. Collectively, our findings provide a structural mechanism of allosteric modulation in mGluR2 and suggest possible strategies for design of future modulators.
Young People as Empirical Experts of Participatory Research in the Age of Information Disorders
Authors: Spurava Guna , Kotilainen Sirkku
Published: July 2022

The main question discussed in this article is: how can young people, as empirical experts, inform the methodologies in studying digital media literacy? Discussion is rooted in a study based on youth consultation organized in Finland in May 2021. The aim of the youth consultation was to help researchers for the European ySKILLS project from three countries (Belgium, Czech Republic, Finland) plan a study on disinformation, conducted later in autumn of the same year. The youth consultation consisted of two parts: an online survey as a qualitative research tool, and an open semi-structured discussion. Based on the results of the youth consultation, it was possible to give recommendations for researchers of the ySKILLS research project. Most useful was information related to youth (not) understanding of algorithm-based communication of social media, which led to suggestions for an additional research question for the ySKILLS study. Overall, the analysis of the results of the youth consultation suggested that young people could act as empirical experts and advisors, especially in the planning stage of research on the uses of digital media and skills on digital media literacy. The next steps could be their consultation in a methodological sense, on how to study their age groups and what topics should be studied.
Newly described nesting sites of the green sea turtle (Chelonia mydas) and the hawksbill sea turtle (Eretmochelys imbricata) in the central Red Sea
Authors: Scott Kirsty , Tanabe Lyndsey K. , Miller Jeffrey D. , Berumen Michael L.
Published: July 2022

Background

There is relatively little published information about sea turtle nesting distribution and seasonality in the Saudi Arabian Red Sea. Upcoming large-scale developments occurring along the Saudi Arabian Red Sea coast could negatively affect many sea turtle nesting beaches with potential impacts on the survival of local populations.

Methods

In 2019, two coastal beaches and three near-shore islands were surveyed for turtle nesting in the central Red Sea. We recorded all emergences, examined beach morphology, and collected sand samples to determine grain size, moisture content and colour.

Results

Sea turtle nesting was found at all surveyed sites, though emergence counts were often low. The limited occurrence of nesting at several previously undocumented sites suggests that nesting activity may be widespread, but sparsely distributed, in the central Red Sea region. In addition, nesting at novel sites appeared to favour the seaward side of islands, a pattern that was not observed in previously documented areas. The substrate of most surveyed sites was composed of calcium carbonate with Ras Baridi as the only exception; it was composed of dark quartz-rich sediment. This study highlights several important sea turtle rookeries while also demonstrating that low levels of nesting occur throughout the region, although inter-annual nesting patterns still need to be determined. Future developments should be steered away from key nesting areas and the seaward bias in marginal rookeries should be taken into account where possible.

Published: July 2022

The new landscape of contingent employment in higher education has presented unique challenges for educational institutions preparing working professionals to assume roles as educators. Unlike their traditional counterparts, adjunct faculty possess disciplinary knowledge and expertise but lack formal, academic preparation for teaching (Anderson, 2009; Cangelosi, Crocker, & Sorrell, 2009; Girard, 2003; Spencer, 2013). Consequently, adjunct faculty require additional tools for on-going development and to feel connected to the organization (AACN, 2017; McDonald, 2010). Such faculty supports influence employee motivation and workplace engagement (Bauer, 2011; Meixner, Kruck, & Madden, 2010) and are positively correlated with job satisfaction and organizational commitment (Gappa, 2000; Lew, 2009). To address the complex needs of adjunct nursing and health professions faculty, the College of Nursing and Health Care Professions has implemented an approach to faculty development using Flipgrid, a video discussion platform. Most commonly used in K-12 education as a learning tool for students, the platform was “flipped” to engage adjunct faculty across health disciplines in a virtual faculty network. Twelve faculty participated in a beta test over the course of a semester to evaluate accessibility, functionality, and overall usefulness of the platform to influence faculty engagement. Results were consistent with the literature pertaining to faculty work engagement (Forbes, Hickey, & White 2010; McDonald, 2010; Raman, 2015). Faculty reported that the professional development activity promoted a sense of community among educators and encouraged collaboration. Ability to engage in meaningful dialog, outside of traditional meetings, was reported as a major theme influencing the sharing of best practices.
Reflective Practice on Social Loafing in College-Level Group Projects
Authors:   University of Houston-Downtown, Sherif Dalia
Published: July 2022

While reflecting on my teaching strategies and researching social loafing for my dissertation, I realized this endeavor has given me a stronger grasp of the pedagogical approaches to facilitate cooperative learning. Observing, sharing, and reflecting on specific social loafing experiences using Gibbs’ reflective framework allowed me, with time, to better conceptualize the dynamics of university-level group projects. Leveraging my experience and insightful research analysis on group dysfunctionalities inside and outside the classroom has gradually reshaped my understanding of the social loafing phenomenon. Nurturing my professional development through this reflective practice allowed me to create an ongoing coaching relationship with students (and later with faculty), and to generate a list of best practices for cooperative learning that can result in higher group achievements and improved learning outcomes.

Much more in store before, and if, H.R. 7666 becomes a reality
Authors: Knopf Alison
Published: July 2022

Last month, the House of Representatives passed H.R. 7666, which would alter much treatment for opioid use disorder and revamp many Substance Abuse and Mental Health Services Administration (SAMHSA) programs (see House passes H.R. 7666, setting stage for revamping SAMHSA, ADAW June 27, https://onlinelibrary.wiley.com/doi/10.1002/adaw.33477). However, there's a lot to be done before, and if, this package passes the Senate.

Published: July 2022

Recently, the inhibiting effects of a clinically approved drug Cepharanthine on severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) have attracted widespread attention and discussion. However, the public does not understand the relevant research progress very well. This paper aims to introduce a brief history of studies on the effects of cepharanthine against SARS‐CoV‐2, including “discovery of anti‐SARS‐CoV‐2 activity of cepharanthine in vitro”, “potential mechanisms of cepharanthine against SARS‐CoV‐2”, “confirmation of cepharanthine's anti‐SARS‐CoV‐2 activity in vivo”, “potential approaches for improving the druggability of cepharanthine” and “clinical trials of cepharanthine treating SARS‐CoV‐2 infection”. Taken together, cepharanthine is believed to be a promising old drug for coronavirus disease‐19 (COVID‐19) therapy.
Interfacial Exciplex Host to Release Interfacial Accumulated Charges for Highly Efficient and Bright Solution‐Processed White Organic Light‐Emitting Diodes

White organic light‐emitting diodes (WOLEDs) have attracted extensive attention and are considered as an ideal next‐generation lighting source. However, maintaining high efficiency and high color rendering index (CRI) in WOLEDs still faces great challenges. The charges accumulation at the interface leads to nonradiative recombination and further Joule heat, which is a source of efficiency decrease and device degradation. In this paper, the interfacial exciplex is designed as the host for high efficiency; the blue thermally activated delayed fluorescence (TADF) material and the red phosphorescent material are employed as guests for high CRI. Due to the interfacial exciplex host, electrons don't need to overcome the potential barrier to inject into the light‐emitting layer, but can directly compound with holes at the interface, so as to release the interfacial accumulated charges and improve the recombination efficiency of carriers. Also, a suitable energy level gradient for hole injection transmission is constructed. Finally, WOLEDs with a current efficiency of 52.8 cd A−1, an external quantum efficiency of 22.9 %, the Commission Internationale de I'Eclairage (CIE) coordinate of (0.35,0.39), and the high CRI of 80 are obtained, which are the highest values ever achieved by the solution processed WOLEDs based on blue TADF emitters.

Zwitterionic surfaces are increasingly explored as antifouling coatings due to their propensity to resist protein, bacterial, and cell adhesion and are typically applied as polymeric systems. Here, the self‐assembly of strongly interacting small molecule amphiphiles is reported to produce nanoribbons for antifouling applications. Synthesized amphiphiles spontaneously form micrometers‐long nanoribbons with nanometer‐scale cross‐sections and intrinsically display a dense coating of zwitterionic moieties on their surfaces. Substrates coated with nanoribbons demonstrate concentration‐dependent thicknesses and near superhydrophilicity. These surface coatings are then probed for antifouling properties and substantial reductions are demonstrated in protein adsorption, bacterial biofilm formation, and cell adhesion relative to uncoated controls. Harnessing cohesive small molecule self‐assembling nanomaterials for surface coatings offers a facile route to effective antifouling surfaces.
Enhancing Recurrent Droplet Jumping Phenomena on Heterogeneous Surface Designs
Authors: Lee Jonggyu , Won Yoonjin
Published: July 2022

Coalescence‐induced droplet jumping phenomena on superhydrophobic surfaces can significantly enhance their heat transfer performances by effectively removing droplets from the surfaces. However, understanding the ideal design for condensing surfaces is still challenging due to the complex nature of droplet dynamics associated with their nucleation, coalescing, and jumping mechanisms. The intrinsic dynamic nature of droplet behaviors suggests the use of hierarchical concave morphology to account for the different length scales associated with each transport phenomenon. The hierarchical morphology thereby enables heterogeneous wetting characteristics by realizing both microscale droplets on superhydrophobic surfaces and nanoscale pinning regions beneath the droplets by arresting liquid residues after droplet jumping. Heat transfer performances are further examined by extracting physically meaningful descriptors, such as nucleation sites, droplet growth rates, and droplet jumping frequency, showing 44% enhancements when droplet nucleation sites are designed in selective locations.

Published: July 2022

Integration of photovoltaic devices on the deformable surfaces of plants and animals is challenging, as most of the photovoltaic devices possess no stretchability which severely restricts the underneath deformable substrates and causes potential delamination of the devices from the substrates due to large shear stress. Here, techniques to achieve stretchable photovoltaic devices through chemically thinning flexible solar cells and intermediate hard–soft transition layers are proposed. The resulting photovoltaic devices are only 25 µm in thickness with a radius of curvature of 1 mm, offering excellent adaptability to leaves and many curved surfaces. The intermediate layer that is based on silicone adhesive with low modulus provides an interface between non‐stretchable photovoltaic devices and deformable substrates, resulting in a stretchability of the overall structures larger than 140%. Key parameters of the photovoltaic device such as open‐circuit voltage, short circuit current, fill factor, and conversion efficiency indicate the excellent performance of thinned devices. Potential applications of ultra‐thin photovoltaic devices in energy harvesting and light intensity sensing on stretchable substrates are demonstrated, suggesting the practical use of the devices in constructing stretchable self‐powered wearable systems for agriculture and healthcare monitoring.

Highly efficient inter‐conversion of different types of energy is the core of science and technology. Among them, electrochemiluminescence (ECL), an emission of light excited by electrochemical reactions, has drawn attention as a powerful tool across diverse fields in addressing global energy, environment, and health challenges. Nonetheless, the ECL efficiency (ΦECL) of most luminophores in aqueous solutions is low, significantly hampering their broad applications. Along this line, developing ECL luminophores with high ΦECL and understanding the associated intrinsic factors is highly envisioned. Herein, taking carbon nitride (CN) with rigid 2D backbones as an emerging model luminophore, it is reported that the orbital delocalization is a unified and quantifiable factor for its ΦECL. Behind the complicated transformation of molecular structures of cyano‐terminal groups and triazine/heptazine basal frameworks, the orbital delocalization of CN is found to be generally improved at an elevated condensation temperature. Such intrinsic evolution in electronic structure favored the electron injection in excitation and follow‐up photon emission in ECL for CN. As a result, the cathodic ΦECL of CN is remarkably improved to a new milestone of 24‐fold greater than the previous record.
