Published: October 2023

Positive and negative feelings are felt by all of us in our lives. When an individual goes through an unjust, personal humiliating or hurtful event which results in psychological stress and even strong urge for revenge, the individual is suffering from embitterment (Linden, 2003). Students play vital role in make or break of any society. It is essential to address the emotional disturbances they might have. Current study explores the phenomenon of Embitterment in university students. Data was collected from students using Semi structured interviews. Thematic analysis was used for data analysis. Assessment of happenings in life of students, negative impacts of bad happenings and unfairness, positive and negative reactions to unfair behavior and ways to overcome it are discussed. It was concluded that if events in students’ life are looked into carefully then possible reactions can be identified. This way it leads to have more control on embittered mind and solutions can be found. This study will contribute in helping students for friendly atmosphere to grow academically and have a better life in general.
Omsorgskrisen og udfordringerne til velfærdsstatens bæredygtighed
Authors: Hansen Lise Lotte
Published: October 2023

At give og modtage omsorg er helt grundlæggende for os som mennesker, men mangel på arbejdskraft og tid samt et dårligt arbejdsmiljø fører sammen med en ”tynd” omsorg til en omsorgskrise. Tilmed risikerer de tre mest fremtrædende løsninger på krisen - mere ledelse, mere teknologi og mere familie og civilsamfund - at forstærke krisen og dermed udfordre velfærdsstatens bæredygtighed. Denne artikel diskuterer, hvad vi skal inkludere, når vi taler om en omsorgskrise i den danske (nordiske) velfærdsstat, hvad der kendetegner denne, og hvilken betydning den har for velfærdsstatens bæredygtighed. Artiklen trækker på analyser og diskussioner i antologien ”A Care Crisis in the Nordic Welfare States? Care work, gender equality and welfare state sustainability” (Hansen, Dahl og Horn, 2022).

Authors: Enes Esra , Sayğılı Başak
Published: October 2023

Zero waste fashion design is a way and at the end of the pattern designing process occurs no cut-and-sew waste. Modular fashion design is a process in that one garment can have the appearance of different designs which can be modified by the consumer. The zero waste fashion design and modular fashion design are considered together as a multiple design methodology to supply sustainable fashion production. Although both design techniques are completely unique, the common aim of sustainability design results can be reached through the combination of the two.
In this study, a collection was designed by integrating these two design methodologies: zero waste and modular fashion. If consumers have an active role in the sustainable design process, the responsibility for sustainable fashion design falls partially on them. The consumer is one of the three pillars of sustainable design philosophy, so they have a major role in helping create a balance on the sustainable fashion production and a sustainable fashion market. Thanks to this harmony, the design process should consider consumer-centered design options and consumer demands.
In this study, an experimental development practicing method via modular and zero waste fashion design methods were used to create a suggested collection. At the end of this study, three garments were designed for that suggested collection, and each can be worn in three or four different looks.

Published: October 2023

The requirements placed on the textile industry are changing drastically. Zero-emission targets for 2030 and beyond require cross-sectoral changes. This also challenges the textile industry to find viable all-in solutions that satisfy social, economic, and sustainable requirements. Currently, the use of textiles in transdisciplinary sectors demands a high level of tailor-made solutions. This requires a broad understanding of the processed materials, complex multiphysics as well as machine settings. Hence, to consolidate high production rates with optimal energy consumption and the use of sustainable resources, systematic research and product development need to be pursued. The digitalisation of research and production in the textile industry aids to close the gap between the complex production processes and the quality measure of the end products. For this purpose, a systematic approach comprising experimental measurements and emerging digital technologies is used. nonwoven manufacturing machine park results have been used for the benchmark study.

Published: October 2023

Dyestuffs are used in almost every industry. However, due to the negative effects of synthetic dyestuffs on the environment and human health, environmentally friendly natural dyestuffs have gained importance in recent years, especially in the textile sector. Mostly plant and plant waste-based dyes are used in coloring fabrics with natural dyes. However, with the developments in the field of biotechnology, there are also studies in which pigment is produced by microorganisms. Within the scope of this study, 100% cotton woven fabric was dyed using 6 different processes with 3 bio-colors, pink, blue and brown, produced by bacterial fermentation. The dyeings were carried out in the absence of chemicals, in the presence of salt, salt-soda, salt-alum, salt-soda-alum and alum respectively. In order to evaluate the dyeing performance, the CIELab values of the fabrics were measured and their color fastness to washing, water, alkali and acid perspiration and also dry and wet rubbing fastness were checked. As a result of the studies, it was concluded that each dyestuff react in a different way with a different process. While the most suitable process for blue and pink bio-color is that salt used process, the highest K/S value with brown bio-color was obtained as a result of dyeing with salt-soda. All fastness values of the dyed fabrics were quite good. As a result of the trials, it can be said that laboratory-scale studies of bio-colors obtained by bacterial fermentation are promising for the future.

Published: October 2023

In the textile and clothing sector, a wide range of auxetic textiles have been made and shown great application potential in many areas. Creating auxetic effect at the yarn stage is relatively a simple approach since helical auxetic yarns (HAY) can be made only by winding or twisting different conventional filaments together with existing spinning machinery. Employing sports safety equipment is a cost-effective solution for avoiding injury and increasing the safety and protection. In the area of materials development for sports safety equipment, an important candidate is auxetic materials. In this study, polyester filament/elastane based helical auxetic yarns (HAY) and knitted fabrics from the yarns were developed that will offer dampening effect against injuries during sports activities. Effects of count of the elastane component and the presence of a third component in the HAY structure on the auxetic behaviour of the knitted fabrics were also studied.

Published: October 2023

Using leftover industrial curtain fabrics, this study aims to develop environmentally friendly acoustic panels. In this context, two forms of curtain fabric waste, blackout and dimout, which are segregated as waste from post-production process within Oba Perdesan, are transformed into fiber utilizing mini shredder. The hot press method is used to produce composite samples made of 100% blackout and 50% blackout/ 50% dimout fabric waste in two different thicknesses (0.5 and 1 cm). The thickness, density, basis weight, FTIR, sound absorption coefficient, and sound transmission loss of the manufactured panels are measured. The FTIR analysis reveals the distinctive peaks of the raw materials of the structures, while the acoustic test results show that the sound absorption coefficient and sound transmission loss increase along with the thickness and basis weight of the structures, respectively. While the 1 cm blackout/dimout blend sample has a superior sound absorption coefficient for 2000 Hz with 0.81, the 1 cm 100% blackout sample performs highest with 10dB sound transmission loss. The produced panels aid in solid waste management while consuming minimal raw materials, and an essential step is taken toward the development of sustainable, practical, and decorative panels.

Published: October 2023

As a result of rapid population growth and industrialization, wastewater generated in various sectors poses a threat to the environment and living things.Textile industry wastewater comes first among these wastewater sources.These wastewaters contain dyestuffs and different chemicals. These waters, which contain many impurities, must be treated well, otherwise they may cause serious problems in the environments where they are discharged. Various physical, chemical and biological methods are used for color removal in wastewater. However, due to the cost and low efficiency of these methods, researches are carried out on innovative and more economical methods. Among the new technologies, advanced oxidation processes (AOPs) are highly efficient new methods being studied for the purification of certain impurities that cannot be removed by general techniques. AOP methods include photocatalytic reaction with UV, ultrasound, Fenton/Peroxide, ultrasound sound waves and similar reactions. One of these methods is ozonation method. In this study, ozone decolorization of wastewater after disperse dyeing taken from textile dyehouse was investigated. In the determined procedure, the removal of color by ozonation method, which is one of the advanced oxidation methods for wastewater recipes after dyeing, was investigated and the color absorbance and COD values of the samples were examined and the results were evaluated.
“Ir despacio y con cautela porque son cambios radicales”: narrativas de profesionales psi en torno a las intervenciones corporales por motivos de identidad de género en Buenos Aires, Argentina
Authors: Del Monaco Romina
Published: October 2023

The purpose of this research is to analyze the narratives of psychologists and psychiatrists in terms of how they address matters concerning gender and sexuality. The qualitative research, which began in 2020, involved thirty in-depth interviews with psychologists and psychiatrists working in Buenos Aires. The approach used to conduct the study of the data was narrative analysis. Specifically, the focus is on exploring the narratives related to gender-affirming medical interventions among the LGTBIQ+ community. The unique features of the Argentine context, with its advancements in acquired rights through sexual dissident activism in the last decade, make this study particularly relevant and offer an original contribution from the field of socioanthropological health studies. In particular, the Gender Identity Law enacted in 2012 regulates name change, registry updates, and access to medical interventions (surgical and hormonal) without the need for psychiatric/psychological consultations. This aspect sparks debates within expert knowledge circles, where pathologizing notions are problematized. Simultaneously, it instigates discussions about certain bodily schemas that are more or less recognized/accepted. While the analysis reveals an increasing number of spaces working from a gender perspective, in other cases, conceptions persist that are influenced by a heteronormative and cissexist logic. In these cases, conceptions of corporeality come into play that reproduce, based on the notion of sex as something biological, the female/male binary. Thus, certain practices and bodily interventions fall within the realm of what is expected, while others, such as when the self-perceived gender does not align with the assigned gender at birth, give rise to narratives emphasizing the importance of “going slowly,” referencing their “radical” nature, and the “irreversibility” involved.

Published: October 2023

Chile is one of the fastest aging countries in Latin America, and the country is currently at an advanced stage of demographic transition. Projections highlight that that in another decade, Chile will emerge as an aging economy. Within the framework of the Fondecyt Regular 1201115 project: “Gender and Aging: An Ethnography on the Social and Moral Organization of Care in the Peñalolén commune (Santiago, Chile),” in this article, we address the findings of a case study on the social organization of elderly care in the Peñalolén commune (Metropolitan Region, Chile). We do so in conjunction with social and gender inequalities from a feminist perspective. The aim of the article is to analyze the social perceptions about aging held by professionals of municipal services working with the elderly population in this specific context. We conducted interviews with these workers using an ethnographic approach that integrated both digital and in-person methodological strategies, and subjected the information collected to a thorough discourse analysis using MaxQDA software (2001 version). The results reveal that the interviewed professionals’ perceptions of old age intermingle the definitions of old age derived from regulatory and public policy frameworks with their own personal and professional experiences in the communal territory. They also demonstrate the multidimensional nature of the inequalities faced by the elderly in Peñalolén, perceived by professionals as demands to be addressed in the exercise of their work. In sum, we propose a perspective of old age and aging that considers its complexity in terms of situated territorial experience by applying ethnographic listening with a gender perspective of the various actors working with the elderly individuals in each context.

In this work, TiN and VN coatings were applied on aluminium electrodes by direct current (DC) magnetron sputtering in order to study the influence of the protective coatings on the electrical impedance of the substrate. The structure of the samples was studied using X-ray diffraction (XRD). The microhardness of the substrate and the coated samples was also determined. The electrical impedance of the substrates with and without coatings was also studied and the results were used for evaluation of the applicability of such coatings for interface electrodes for flexible electronics. Electric impedance spectroscopy in a wide frequency range was applied for interlayer and surface contact properties determination. Results showed improved stability and conductivity of the electrodes coated using the TiN and VN thin films, particularly in the low frequency range.

Published: October 2023

Rhodiola rosea L. is a high-altitude medicinal plant with various health-beneficial effects, associated mainly with the phenolic substances salidroside and rosavins (rosavin, rosin and rosarin). The intensive collection of R. rosea rhizomes and roots to be used in folk medicine and pharmacy has led to a decrease of the species natural resources. New opportunities for species conservation and accelerated synthesis of biologically active substances have been provided by various systems for in vitro and ex vitro cultivation. In this study, the salidroside and rosavins content was determined using HPLC analysis in in vitro cultures of R. rosea and further monitored in adapted regenerants grown ex vitro. The targeted secondary metabolites were not detected in the calli and in the roots of 1-month-old regenerants obtained on different nutrient media. The roots/rhizomes of adapted regenerants grown ex vitro in a greenhouse for 1 year and in the mountain for 1, 2 and 3 years produced increasing amounts of salidroside (from 0.4 to 1.2%) and rosavins (from 4.3 to 4.5%). The salidroside to rosavins ratio (1:3.75) in 3-year-old regenerants grown in the mountain was close to the pharmacopoeial standard ratio of 1:3. These results show that R. rosea plants, obtainted by in vitro micropropagation and grown ex vitro are promising for drug production.

Filament/prominence eruptions can have a significant impact on Earth's upper atmosphere and space environment, and are the primary drivers of what is now called space weather. To distinguish the different types of filament eruptions we statistically examine them during the 23rd Solar cycle. In this study we use 159 filament eruptions using the List of interplanetary (IP) Shocks Observed during Solar Cycle 23 (May 1996 – January 2008) and their Source Information Environmental Satellites (GOES) X-ray plots (see Gopalswamy et al. [Gopalswamy N., H. Xie, P. Mäkelä, S. Akiyama, S. Yashiro et al. (2010) Interplanetary shocks lacking type II radio bursts, Astrophys. J., 710, 1111–1126]). It is found that 69% of the filament eruptions are confined eruptions, while 31% are ejective eruptions. Confined eruptions are 110 and 34 events (21%). They are due to active filaments and 76 events (48%) are due to disappearing filaments. The occurrences of active and disappearing filaments during the increasing phase of solar cycle 23 is found to be 80% while in the decreasing phase they are 13%. We have found that the dominant X-ray flare energy of confined eruptions is that of C class. The most common filaments field extent is located between 5 and 15 degrees. The most common flare duration is between 16 and 40 minutes.

Calf diarrhea is an important disease that causes economic losses and E. coli is the primary pathogen. In this study, stool samples were collected from a total of 100 calves with diarrhea. As a result of 16S rRNA PCR analysis, it was confirmed that 50 (96.15%) of 52 E. coli isolates were molecularly E. coli. As a result of molecular pathotyping studies of 50 E. coli isolates, the pathotypes of 21 (42.0%) E. coli strains were identified. E. coli (n = 50) isolates were found to be resistant to amoxicillin-clavulanate by 34%, to ciprofloxacin by 38%, and to trimethoprim-sulfamethoxazole by 60%. Different degrees of antimicrobial resistance genes were detected in 26 (52%) E. coli isolates. In conclusion, a data source was provided for the antimicrobial treatment procedure in calf diarrhea caused by E. coli in our region, and the results that could guide future studies were also brought to the literature.
Hybridization led to a rewired pluripotency network in the allotetraploid Xenopus laevis

Published: October 2023

After fertilization, maternally contributed factors to the egg initiate the transition to pluripotency to give rise to embryonic stem cells, in large part by activating de novo transcription from the embryonic genome. Diverse mechanisms coordinate this transition across animals, suggesting that pervasive regulatory remodeling has shaped the earliest stages of development. Here, we show that maternal homologs of mammalian pluripotency reprogramming factors OCT4 and SOX2 divergently activate the two subgenomes of Xenopus laevis, an allotetraploid that arose from hybridization of two diploid species ~18 million years ago. Although most genes have been retained as two homeologous copies, we find that a majority of them undergo asymmetric activation in the early embryo. Chromatin accessibility profiling and CUT&RUN for modified histones and transcription factor binding reveal extensive differences in predicted enhancer architecture between the subgenomes, which likely arose through genomic disruptions as a consequence of allotetraploidy. However, comparison with diploid X. tropicalis and zebrafish shows broad conservation of embryonic gene expression levels when divergent homeolog contributions are combined, implying strong selection to maintain dosage in the core vertebrate pluripotency transcriptional program, amid genomic instability following hybridization.

Chemoresistance is a major cause of treatment failure in many cancers. However, the life cycle of cancer cells as they respond to and survive environmental and therapeutic stress is understudied. In this study, we utilized a microfluidic device to induce the development of doxorubicin-resistant (DOXR) cells from triple negative breast cancer (TNBC) cells within 11 days by generating gradients of DOX and medium. In vivo chemoresistant xenograft models, an unbiased genome-wide transcriptome analysis, and a patient data/tissue analysis all showed that chemoresistance arose from failed epigenetic control of the nuclear protein-1 (NUPR1)/histone deacetylase 11 (HDAC11) axis, and high NUPR1 expression correlated with poor clinical outcomes. These results suggest that the chip can rapidly induce resistant cells that increase tumor heterogeneity and chemoresistance, highlighting the need for further studies on the epigenetic control of the NUPR1/HDAC11 axis in TNBC.
Inter-species association mapping links splice site evolution to METTL16 and SNRNP27K
Authors: Parker Matthew T , Fica Sebastian M , Barton Geoffrey J , Simpson Gordon G
Published: October 2023

Eukaryotic genes are interrupted by introns that are removed from transcribed RNAs by splicing. Patterns of splicing complexity differ between species, but it is unclear how these differences arise. We used inter-species association mapping with Saccharomycotina species to correlate splicing signal phenotypes with the presence or absence of splicing factors. Here, we show that variation in 5’ splice site sequence preferences correlate with the presence of the U6 snRNA N6-methyladenosine methyltransferase METTL16 and the splicing factor SNRNP27K. The greatest variation in 5’ splice site sequence occurred at the +4 position and involved a preference switch between adenosine and uridine. Loss of METTL16 and SNRNP27K orthologs, or a single SNRNP27K methionine residue, was associated with a preference for +4 U. These findings are consistent with splicing analyses of mutants defective in either METTL16 or SNRNP27K orthologs and models derived from spliceosome structures, demonstrating that inter-species association mapping is a powerful orthogonal approach to molecular studies. We identified variation between species in the occurrence of two major classes of 5’ splice sites, defined by distinct interaction potentials with U5 and U6 snRNAs, that correlates with intron number. We conclude that variation in concerted processes of 5’ splice site selection by U6 snRNA is associated with evolutionary changes in splicing signal phenotypes.

Published: January 2025

The design of cost‐effective electrocatalysts is critical for advancing sustainable energy technologies, particularly for key reactions like the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR) in water electrolyzers and metal–air batteries. Cobalt pentlandite (CNFS) has emerged as a promising candidate, offering high conductivity, stability, and the advantage of using abundant elements. In this study, density functional theory (DFT) calculations reveal that tungsten (W) doping in CNFS, combined with an increased concentration of sulfur vacancies, can effectively shift the d‐band center downward enhancing metal‐sulfur orbital hybridization. These modifications facilitate the desorption of oxygen intermediate while maintaining structural integrity. Additionally, the engineering of this material with a hollow architecture further increases active site exposure, significantly improving catalytic activity. As a result of this multifaceted approach, the W‐doped CNFS catalyst achieves a remarkably low OER overpotential of 241 mV at 50 mA cm⁻2, alongside enhanced ORR activity. Furthermore, the catalyst demonstrates excellent performance in rechargeable zinc–air batteries (ZABs), achieving a peak power density of 100 mW cm⁻2 and sustaining over 650 h of cycling at 4 mA cm⁻2. Overall, this study presents a viable strategy for improving ZAB performance and reducing costs by utilizing efficient and cost‐effective metal sulfides with a cobalt pentlandite structure.

Published: January 2025

Cu‐based catalysts efficiently catalyze the electrochemical conversion of CO2 into high‐value multicarbon (C2+) products. However, it remains a challenge to achieve optimal structural stability, product selectivity, and long‐term catalytic durability. In this study, a well‐active oxide‐derived Cu surface consisting predominantly of Cu2O(111) facets is developed, which contains trace amounts of iodine (I). The Cu2O(111) surface enhances the hydrogenation of *CO and facilitates the asymmetric coupling of *CO and *CHO, while the intercalated iodine boosts the adsorption of CO2 and CO. During the reaction, the release of excess I increases the surface roughness, while the remaining iodine controls the chemical state of the surface Cu. These effects together lead to a Faradaic efficiency of 79.0% and a cathodic energy efficiency of 43.5% for C2+ products at a current density of 300 mA cm−2. Moreover, it is found that periodic electrode treatment with iodide prevents the agglomeration of catalysts and preserves sufficient active iodine sites, ensuring improved catalytic stability for C2+ production. This study provides new insights into the synergistic interactions between Cu─O compounds and iodine and offers a promising route for the development of highly active and durable catalytic systems for long‐term CO2 electroreduction.

LiFePO4 is extensively used as a cathode material in lithium‐ion batteries because of its high safety profile, affordability, and extended cycle life. Nevertheless, its inherently low lithium‐ion transport kinetics and restricted electronic conductivity considerably limit its rate performance. Furthermore, the failure mechanisms specific to various cycling rates are not well examined. This study presents a functional interface layer designed to regulate the rate‐dependent failure behavior of LiFePO4. At elevated charge/discharge rates, this layer facilitates lithium‐ion mobility, decreases internal polarization, alleviates mechanical stress, and reduces structural degradation. At lower cycling rates, it contributes to the formation of a stable cathode‐electrolyte interphase (CEI), effectively suppressing side reactions and minimizing active lithium loss. Consequently, the modified LiFePO4 demonstrates enhanced cycling stability and capacity retention, with capacity retention after 400 cycles at 2C rate increasing from 76.5% to 98.6% and at 5C increasing from 40.2% to 90.0%. Through combinations of experimental data and theoretical analysis, this study elucidates key mechanisms underlying rate‐specific failure regulation, providing valuable insights into the relationship between ion transport dynamics and structural stability. This approach represents an effective strategy for supporting its potential use in advanced energy storage systems that require both rapid charging and prolonged cycling stability.

Aqueous Zn metal batteries (AZMBs) have appealing advantages, including good safety, low cost, and high volumetric energy density. However, serious parasitic reactions and dendrite growth at Zn anodes hinder practical applications of AZMBs. Here, a nature‐inspired strategy is proposed to improve Zn anodes using plant‐cell derivatives as additives for ZnSO4 electrolytes. In the electrolyte, TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl)‐oxidized cellulose nanofibers (TOCN) and calcium lignosulfonate (CL) with specific functional groups modulate the Zn2+ solvation structure. More importantly, they reform a cell membrane/wall‐like functional layer with high mechanical strength and selective Zn2+ transmission/plating on the anode surface, which enables uniform Zn deposition and alleviates side reactions. As a result, symmetric cells using the dual‐additive electrolyte exhibit highly reversible and dendrite‐free Zn stripping/plating behavior for over 2000 and 500 h at 2 mA cm−2/1 mAh cm−2 and 10 mA cm−2/10 mAh cm−2, respectively. Furthermore, a Zn//NH4V4O10 full cell using the electrolyte shows a good cycling stability over 300 cycles with a low negative/positive (N/P) ratio. A high energy density of 92.9 Wh kg−1 can be delivered with limited metallic Zn consumption, showing that the electrolyte has good prospects for practical use.

Organic thermoelectric (OTE) materials are continuously evolving through the development of novel conjugated polymers and corresponding doping methods. FeCl3 doping is the most commonly used method because of its affordability and strong oxidizing power. However, at high dopant concentrations, FeCl3 interferes with the molecular ordering and negatively impacts on the morphology, which causes a substantial decline in performance. To address this issue, in this study, new OTE polymers with π‐conjugation along the pendant side are developed. This unique polymeric structure enables pendant doping with FeCl3 by forming a strong binding complex at the conjugated side chains, where an abundant free volume exists. Consequently, the intermolecular ordering of the OTE polymer is well preserved even under high dopant concentration, thereby enabling a high power factor exceeding 10 µW m−1 K−2 consistently across a wide range of high dopant concentrations (16–32 mM) for the first time. This distinctive doping behavior on the pendant side will provide a new opportunity to develop high‐performance OTE polymers.

The confining effect is essential to regulate the activity and stability of single‐atom catalysts (SACs), but the universal fabrication of confined SACs is still a great challenge. Here, various lattice‐confined Pt SACs supported by different carriers are constructed by a universal co‐reduction approach. Notably, Pt single atoms confined in the lattice of Ni(OH)2 (Pt1/Ni(OH)2) with a high electron‐deficient state exhibit excellent activity for basic hydrogen evolution reaction (HER). Specifically, Pt1/Ni(OH)2 just requires 15 mV to get 10 mA cm−2 and the mass activity of Pt1/Ni(OH)2 is 15 times of commercial Pt/C. Moreover, Pt1/Ni(OH)2 assembled in an alkaline water electrolyzer shows 1030 h durability under the industrial current density of 800 mA cm−2. In situ spectroscopy techniques reveal Pt─H and “free” OH radical can be directly observed for Pt1/Ni(OH)2, confirming the lattice‐confined Pt single atoms play a key role during HER. Further density functional theory uncovers the Pt 3d orbital strongly hybridizes with O 2p and Ni 3d orbitals in Ni(OH)2, which quickly optimizes the electronic state of the Pt site, thus largely reducing the energy barrier of the rate‐determining step to 0.16 eV for HER. Finally, this synthesis method is extended to construct other 9 lattice‐confined SACs.

Unconventional spin‐orbit torques arising from electric‐field‐generated spin currents in anisotropic materials have promising potential for spintronic applications, including for perpendicular magnetic switching in high‐density memory applications. Here, all the independent elements of the spin torque conductivity tensor allowed by bulk crystal symmetries for the tetragonal conductor IrO2 are determined via measurements of conventional (in‐plane) anti‐damping torques for IrO2 thin films in the high‐symmetry (001) and (100) orientations. It is then tested whether rotational transformations of this same tensor can predict both the conventional and unconventional anti‐damping torques for IrO2 thin films in the lower‐symmetry (101), (110), and (111) orientations, finding good agreement. The results confirm that spin‐orbit torques from all these orientations are consistent with the bulk symmetries of IrO2, and show how simple measurements of conventional torques from high‐symmetry orientations of anisotropic thin films can provide an accurate prediction of the unconventional torques from lower‐symmetry orientations.

The effective collection of interfacial tribo‐charges and an increase in load voltage are two essential factors that improve the output energy of triboelectric nanogenerators. However, some tribo‐charges are hardly collected through one or multiple integrated side electrodes based on corona discharge, and their load voltages are limited by air breakdown in adjacent electrodes. In this study, a dynamic quasi‐dipole potential distribution model is proposed to systematically reveal the mechanisms of interfacial tribo‐charge loss. Based on this model, an optimization route is designed to reduce the interfacial charge loss stepwise, achieving a 15‐fold improvement in charge collection from the tribo‐interface. A potential difference enhancement strategy is used for the first time to increase the air breakdown threshold between the inner electrodes and increase the output voltage under a large load. By effective increase in charge collection efficiency and load voltage, a historical record output energy density of 5.03 J m−2 is obtained. This study refined and optimized the interfacial charge loss mechanisms and provided advanced guidance for efficiently extracting energy during the triboelectrification process.

The co‐electrolysis of CO2 and NO3− to synthesize urea has become an effective pathway to alternate the conventional Bosch‐Meiser process, while the complexity of C‐/N‐containing intermediates for C−N coupling results in the urea electrosynthesis of unsatisfactory efficiency. In this work, an electronic spin state modulation maneuver with oxygen vacancies (Ov) is unveiled to effectively meliorate the oriented generation of key intermediates *NH2 and *CO for C−N coupling, furnishing urea in ultrahigh yield of 2175.47 µg mg−1 h−1 and Faraday efficiency of 70.1%. Mechanistic studies expound that Ov can induce the conversion of the high‐spin state Ni2+ (t2g6eg2) of Ni@CeO2−x to the low‐spin state Ni3+ (t2g6eg1), which markedly enhances the hybridization degree of the Ni 3d and the N 2p orbitals of *NO, facilitating the selective formation of *NH2. Notably, the in situ generated *NH2 intermediates can serve as a localized proton donor to promote the electroreduction of CO2 on the adjacent site Ce3+−O to exclusively afford *CO, followed by C−N coupling of each other to efficiently synthesize urea. The strategy of tailored switching of the active site spin state provides a reliable reference to rectify the electronic structure of electrocatalysts for directional CO2 valorization.

Phototransistors are critical components in optoelectronics, and 2D transition metal dichalcogenides (TMDC), such as tungsten diselenide (WSe2), show promise for phototransistor applications due to their strong light‐matter interaction, unique excitonic properties, and high surface‐to‐volume ratio. In 2D TMDC‐based phototransistors, 1/f noise, caused by complex defect states, acts as a dominant low‐frequency noise (LFN) and is crucial for obtaining accurate photodetection characteristics. However, many studies still overlook LFN and focus on enhancing photocurrent or response time. In this study, the importance of LFN analysis is highlighted in WSe2 phototransistors and demonstrate reduced noises and enhanced photodetection performance through the suppression of metal‐induced gap states (MIGS) that act as noise sources by utilizing semimetal bismuth (Bi) contact. The WSe2 phototransistors demonstrated ≈1000 times lower noise, 100 times higher responsivity, and 10 times higher specific detectivity than devices with conventional metal contacts. The results of this study suggest that reducing LFN in photodetection devices, such as by suppressing MIGS, can be an efficient way to enhance device performance.

MXenzymes, a promising class of catalytic therapeutic material, offer great potential for tumor treatment, but they encounter significant obstacles due to suboptimal catalytic efficiency and kinetics in the tumor microenvironment (TME). Herein, this study draws inspiration from the electronic structure of transition metal vanadium, proposing the leverage of TME specific‐features to induce structural transformations in sheet‐like vanadium carbide MXenzymes (TVMz). These transformations trigger cascading catalytic reactions that amplify oxidative stress, thereby significantly enhancing multimodal tumor therapy. Specifically, the engineered HTVMz, coated with hyaluronic acid, exhibits good stability and generates a thermal effect under NIR‐II laser irradiation. The thermal effect, combined with TME characteristics, facilities a structural transformation into ultra‐small vanadium oxide nanozymes (VOx). The enlarged surface area of VOx substantially enhances ROS regeneration and amplifies oxidative stress, which promotes lysosomal permeability and induces endoplasmic reticulum stress. The high‐valent vanadium in VOx interacts with intracellular glutathione, disrupting redox homeostasis and intensifying oxidative stress further. These amplifications accelerate tumor apoptosis, induce ferroptosis, and suppress HSP90 expression. Consequently, the heightened thermal sensitivity of HTVMz synergistically promotes tumor cell death via multimodal therapeutic pathways. This study presents an innovative strategy for tumor catalytic therapy by manipulating MXenzymes structures, advancing the field of catalytic therapy.
