Authors: A. B BANDE , M. M GARBA , S ALIYU , B.S HAMZA , A SHEHU
Published: September 2022

Solar energy is a free natural resource but its harvesting requires a high capital investment whichprohibits its maximum exploitation. A Parabolic Dish Solar Collector (PDSC) with a thermalstorage system was been constructed and developed to harness solar beam radiation. The thermalstorage system and PDSC were constructed using locally and less cost materials such asgalvanized metal sheet and steel rods curved to obey the equation of a parabola then weldedtogether with circular support rings which was then lined with stainless steel reflector pasted forthe construction of PDSC. The receiver was made of blackened aluminium material incorporatedwith coiled copper tube carrying water as the heat transfer fluid. A parabolic dish which acts of aheat collector is used to track and reflects solar radiation at a single point (focus) on a receiverabsorber. Heat transfer from the solar collector to the storage tank was done by usingthermosyphonic principle to circulate the water (heat transfer fluid) between storage tank andheating system (receiver). The evaluation of thermal storage and analyzing the efficiency oftracking and non-tracking parabolic dish solar collector was carried out during month of June,2020 for the composite climate of Sokoto. According to the finding, the efficiency of trackingPDSC with thermal storage system and non- tracking PDSC with thermal storage tank weredetermined and obtained to be 52.9% and 50% respectively.Keywords: thermal efficiency, parabolic dish collector, solar radiation, storage system andstainless steel reflector.

Published: September 2022

This research was designed to compare two methods for determination of vitamin C (Ascorbicacid) content in Annona squamosa peel and pulp as well as in Velvet tamarind pulp. Vitamin Ccontent of fresh fruit parts were determined by titrimetric and spectrophotometric methods usingpotassium permanganate as chromogenic reagent. Absorbance was measuredspectrophotometrically at 530nm. The titration method was carried out using iodometric backtitration. The results obtained from the study revealed that there was significant differencebetween the two methods and the higher vitamin C content was recorded in Annona squamosa.Both samples could therefore be used to supplement vitamin C daily intake requirements.Keywords: Annona squamossa, Valvettamarind, Vitamin C, Ascorbic acid, Spectrophotometer.
Contribution and Relevance of Imam Abu Hanifah and Zayd bin Ali's Thinking on Contemporary Online Business Practices
Authors: Mukholik Ayis
Published: September 2022

This article discusses legal studies on consumer protection for the circulation of expired food. This is because often found in many stores there are some items that have expired. Juridically, the distribution of expired food is against the laws and regulations. Law Number 8 of 1999 concerning Consumer Protection mandates that “business actors are prohibited from producing and/or trading goods and/or services that do not include the date. The provisions of this law, in addition to providing rights to consumers to obtain valid information on the goods to be purchased, have also prohibited business actors from trading expired goods.
Renal Mucormycosis in a Healthy Boy for Ten Years: A Novel Case Report
Authors: Li Yufeng , Zhu Yaju , Li Ping , Fang Xiaoliang , Huang Lisu , Chen Feng
Published: September 2022

: Mucormycosis is rare in urinary tract infections. Renal mucormycosis is considered in immunocompromised patients and is associated with a high mortality rate. Herein, we presented the first case of a non-invasive fungus ball caused by a Rhizopus species confined to the unilateral kidney in a healthy boy for approximately ten years. The etiology was identified using next-generation deoxyribonucleic acid (DNA) sequencing. The patient recovered completely after nephrectomy without bladder irrigation. Therefore, clinicians must have a high index of suspicion for fungal infections in refractory urinary tract infections. Next-generation DNA sequencing technology can be used for an accurate diagnosis.
Aliens and Monsters: Aristotle’s Hypothetical “Defense” of Natural Slavery
Authors: Harwood William ,   Polish Academy of Sciences
Published: September 2022

This paper examines Aristotle’s discussion of slavery, showing his description of actual slavery to be an indictment and those regarding natural slavery to be a hypothetical investigation of a separate kind. Aristotle not only precludes the inclusion of natural slaves and freepersons in a single natural kind, but also articulates such bizarre requirements for natural slaves that they ultimately cannot exist. While this reading avoids notorious difficulties associated with Aristotle’s discussion of slaves, it replaces them with impossible preconditions for just slavery—so much that one must consider the possibility that Aristotle did not believe there was such a thing as “just” slavery. Was Aristotle’s otherwise acute mind blinded by the prejudices of his time? Or is this the inevitable result of “defending” the indefensible: an ad absurdum that has been ironically misunderstood and anachronistically misapplied to modern race and racism?
Friedrich Nietzsche and Information Society: Dangers of the Radical Social Division
Authors: Vdovychyn Ihor , Bun Viktoriya , Khoma Nataliia ,   Polish Academy of Sciences
Published: September 2022

The purpose of the article is to analyse Friedrich Nietzsche’s ideas about the radical social division of society and the domination of the elite over the masses in the context of the latest socio-economic, technological and political realities of the post-industrial society. The authors emphasize the existing social demand for the study of threats that arise from social divisions due to the influence of the information society. In these processes, the authors trace a peculiar kind of recent interpretation of Nietzsche’s ideas about the “Übermensch,” owing to a radical change in the information space under the influence of the technological revolution. It is stated that the modern information society forms a new radical social division into the upper class of intellectuals and the general mass of consumers, provokes the emergence of a “divided civilization,” where under the slogans of supporting the idea of meritocracy, a society with new social divisions is formed. Ignoring the humanistic meaning of rights and freedoms, perceiving them exclusively as a technological tool for the introduction of irresponsibility make it possible to justify the rule of Nietzsche’s “Übermensch.” The “Übermensch” is now the bearer of knowledge, which is necessary for modern civilization. Nietzsche’s calls for the destruction of cultural tradition are used as a justification for the rejection of personal freedom, human rights, as well as the rejection of state institutions capable of protecting them. The authors conclude that the information society, which is based on technological innovations, faces a range of socially dangerous consequences, as well as the deformation of the system of established values. Thanks to the manipulative tools generated by technological progress, new formats of inequality are emerging and taking root. The appearance of powerful information resources strengthens the ability to control the behaviour of the individual, expands the power of a small group of people who control the information space. This is what actualizes Nietzsche’s statements about the radical division of society and the domination of the elite over the masses in the new socio-economic and technological realities.
The Alienation Phenomenon and the Communicative Model of the Human Society Evolution

Published: September 2022

The aim of this work is to consider individual symptoms and areas of alienation in the history of mankind and in the modern information society, and the disclosure of its logic and patterns. Methodologically, the study is based on the historical, information and cybernetic approaches. The paper points to a positive feedback between the amount of knowledge in alienated form and figures of society, the development of its comprehensive intelligence. New forms of exclusion, which exist in the form of artificial intelligence, robotics, and global computer networks, are analysed. The findings suggest a communicative model of the interaction of mankind with man-made external memory, which describes a non-linear process of communicating to it all human knowledge and intellectual abilities. It is emphasized that the contradiction between man and the material world created by him is the main contradiction of modernity.
Instrumental Reason and Science—Max Horkheimer’s View
Authors: Czarnocka Małgorzata ,   Polish Academy of Sciences
Published: September 2022

The paper analyses today partly forgotten Max Horkheimer’s conception of instrumental reason which presents this reason differently from the definition widespread today (claiming that it consists in adopting suitable means to set ends). Horkheimer relates instrumental reason to subjective one, seeing the former as a degenerate form of the latter. His theory is far more philosophical than the dominating today conceptions which do not consider the problem of instrumental reason philosophical any longer and instead move it step by step to the domain of a nonphilosophical decision theory. The paper analyses in particular Horkheimer’s beliefs claiming that 1) it is science which founds instrumental reason, and therefore 2) it is science which is the main source of oppressiveness and degradation of the contemporary civilization. It is shown among other things that Horkheimer misunderstands some properties of science and its operations and this leads to his incorrect presentation of the role of instrumental reason.

Background: Optimal analgesic maintenance for severe cancer pain is unknown. This study evaluated the efficacy and safety of intravenous patient-controlled analgesia (IPCA) with continuous infusion plus rescue dose or bolus-only dose versus conventional oral extended-release morphine as a background dose with normal-release morphine as a rescue dose to maintain analgesia in patients with severe cancer pain after successful opioid titration. Methods: Patients with persistent severe cancer pain (≥7 at rest on the 11-point numeric rating scale [NRS]) were randomly assigned to 1 of 3 treatment arms: (A1) IPCA hydromorphone with bolus-only dose where dosage was 10% to 20% of the total equianalgesic over the previous 24 hours (TEOP24H) administered as needed, (A2) IPCA hydromorphone with continuous infusion where dose per hour was the TEOP24H divided by 24 and bolus dosage for breakthrough pain was 10% to 20% of the TEOP24H, and (B) oral extended-release morphine based on TEOP24H/2 × 75% (because of incomplete cross-tolerance) every 12 hours plus normal-release morphine based on TEOP24H × 10% to 20% for breakthrough pain. After randomization, patients underwent IPCA hydromorphone titration for 24 hours to achieve pain control before beginning their assigned treatment. The primary endpoint was NRS over days 1 to 3. Results: A total of 95 patients from 9 oncology study sites underwent randomization: 30 into arm A1, 32 into arm A2, and 33 into arm B. Arm B produced a significantly higher NRS over days 1 to 3 compared with arm A1 or A2 (P<.001). Daily NRS from day 1 to day 6 and patient satisfaction scores on day 3 and day 6 were worse in arm B. Median equivalent-morphine consumption increase was significantly lower in A1 (P=.024) among the 3 arms. No severe adverse event occurred in any arm. Conclusions: Compared with oral morphine maintenance, IPCA hydromorphone for analgesia maintenance improves control of severe cancer pain after successful titration. Furthermore, IPCA hydromorphone without continuous infusion may consume less opioid.
Medkulturna priredba mednarodnega Vprašalnika telesne dejavnosti (IPAQ) za rabo	na področju izobraževanja
Authors: Marinšek Miha , Bedenik Klemen , Tekavc Janja
Published: September 2022

Background: Regular moderate and vigorous-intensity physical activity (PA) is very important for health promotion and prevention of diseases. Frequency and the amount of PA can be monitored with direct and indirect measurements; the former is more accurate than the latter, which is, on the other hand, easier to use and more cost-effective. One of the most commonly used indirect methods is a self-report International Physical Activity Questionnaire (IPAQ), which comes in short (SF) and long forms (LF). Despite its wide cross-cultural use, IPAQ has not yet been adapted for use in the Slovenian language. The main purposes of the study were to produce a reliable Slovenian version of IPAQ-LF for use in education.

Methods: A back-translation method involving four translators and one native English-speaking reviewer was used to adapt an IPAQ-LF questionnaire from English into the Slovenian language. The ease of use and comprehensibility of Slovenian IPAQ-LF was first pilot-tested on four teachers, then the reliability of a questionnaire was tested and retested on a sample of sixty-eight preschool and primary school teachers.

Results: Collected data were analysed with several statistical methods, and the results revealed a high degree of test-retest reliability and internal consistency for both groups of teachers. Preschool teachers reported higher levels of moderate (1138±265 min/week vs. 870±1074 min/week) and vigorous-intensity (446±430 min/week vs. 106±157 min/week) PA as well as walking (996±337 min/week vs. 690±1173 min/week) than primary school teachers.

Conclusions: The study has proven that the Slovenian IPAQ-LF version is reliable for use in education.

Published: September 2022

Музика је од самог рођења саставни део живота сваког детета и има огроман утицај на његов развој. Музичко описмењавање деце у разредној настави подразумева дуготрајан и сложен процес упознавања нотног текста, његовог читања и певања. У настави од првог до четвртог разреда деца најлакше памте и изводе народне песме. Ова чињеница је веома значајна јер помоћу народних песама деца уче традицију и значај очувања народног блага. Један од задатака наставе музичке културе на млађем школском узрасту јесте и упознавање детета са основама музичке писмености. Један од најважнијих циљева почетне наставе солфеђа јесте поставка основних тонских висина. Тонске висине се обрађују песмама моделима, односно функционалном методом Миодрага Васиљевића. За све песме моделе заједничко је то што се почетни слог текста песме поклапа са солмизационим именом тона којим песма почиње. Памтећи текст песме, ученици памте и тонску висину од које песма почиње. Рад представља анализу препоручених композиција за певање у млађим разредима основне школе из Програма наставе и учења за први и други разред и Правилника о наставном плану и програму за први, други, трећи и четврти разред основног образовања и васпитања по којима се реализује настава музичке културе.

Од малих ногу, појединац тежи ка изражавању креативности. Током школског периода долази до смањења заинтересованости за даљи развој креативности, а највероватније због устаљених норми и правила које налажу школа и наставници. Управо из овог разлога се примењују ваннаставне активности, у циљу да се креативност не запостави, а да се ученици више заинтересују за наставни предмет или га усаврше. Под појмом „ваннаставне активности“ подразумевамо све оне активности којима се ученици баве изван часова редовне наставе, предвиђених планом и програмом. Њихов главни значај се огледа у томе да оне представљају део учениковог времена, којим ученик задовољава своја интересовања и знатижељу. Ваннаставне активности се реализују у просторијама образовних институција, као што су: учионице, кабинети и радионице, лабораторије, атељеи, а могу се реализовати и на отвореном простору у природи или урбаној средини. У раду ће бити обрађене следеће ваннаставне активности – додатна настава, секције и зимска/летња школа, односно радионица. Такође, осврнућемо се и на исказивање естетског размишљања ученика и шта је то битно да бисмо естетски проценили неки предмет или уметничко дело, шта је потребно да откријемо у њему, оно што нас привлачи, радује или изазива нека осећања. То свакако није једноставно и за тако нешто је потребно припремити се, школовати, а исто тако и стећи широко знање и искуство.
La hipersexualización de la mujer en los videojuegos de lucha
Authors: Molares Cardoso Julinda , Badenes Plá Vicente , Legerén Lago Beatriz
Published: September 2022

Objetivo: El propósito de esta investigación es analizar la evolución del primer personaje femenino de lucha que se presentó en el videojuego Street Fighter. Chun Li se convierte en la primera mujer en aparecer en un juego de combate de uno contra uno. El objetivo principal es el estudio de la evolución a nivel visual del personaje durante sus más de treinta años de existencia.

Diseño/metodología/enfoque: Se establece una metodología de carácter cuantitativa y descriptiva basada en el análisis de contenido. Se elabora una ficha de investigación con 32 parámetros en los que se analiza la evolución de la imagen del personaje desde su primera aparición en el año 1991 hasta su última aparición en el año 2021. Se han extraído 703 datos relacionados con las dimensiones morfológicas de Chun Li durante el periodo estudiado.

Resultados: Los creadores del personaje de Chun Li no han sabido adaptarse  a los cambios que demanda el mercado respecto a la hipersexualización de la imagen de la mujer en los videojuegos. Chun Li representa unos valores de lucha y constancia en un cuerpo altamente sexualizado e irreal que no se corresponde con una figura femenina realista. Se están dando pasos en este sentido pero, aunque casi la mitad de los jugadores son mujeres, los personajes femeninos todavía están diseñados por hombres y para hombres.

Originalidad/Contribución: El trabajo presenta originalidad en la investigación de la evolución gráfica de los personajes de videojuegos, al plantear una metodología propia con la creación de una ficha de análisis replicable en otros personajes.
The cold-stress responsive gene DREB1A involved in low-temperature tolerance in Xinjiang wild walnut
Authors: Han Liqun , Ma Kai , Zhao Yu , Mei Chuang , Mamat Aisajan , Wang Jixun , Qin Ling , He Tianming
Published: September 2022

Background

Low-temperatures have the potential to be a serious problem for plants and can negatively affect the normal growth and development of walnuts. DREB1/CBF (Dehydration Responsive Element Binding Protein 1/C-repeat Binding Factor), one of the most direct transcription factors in response to low-temperature stress, may improve the resistance of plants to low-temperatures by regulating their functional genes. However, few studies have been conducted in walnut. The Xinjiang wild walnut is a rare wild plant found in China, with a large number of excellent trait genes, and is hardier than cultivated walnuts in Xinjiang.

Methods

In this work, we identified all of the DREB1 members from the walnut genome and analyzed their expression levels in different tissues and during low-temperature stress on the Xinjiang wild walnut. The JfDREB1A gene of the Xinjiang wild walnut was cloned and transformed into Arabidopsis thaliana for functional verification.

Results

There were five DREB1 transcription factors in the walnut genome. Among them, the relative expression level of the DREB1A gene was significantly higher than other members in the different tissues (root, stem, leaf) and was immediately un-regulated under low-temperature stress. The overexpression of the JfDREB1A gene increased the survival rates of transgenic Arabidopsis lines, mainly through maintaining the stability of cell membrane, decreasing the electrical conductivity and increasing the activities of antioxidant enzymes including superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT). Additionally, the expression levels of cold-inducible genes like AtKIN1, AtERD10, AtRD29A, AtCOR15A and AtCOR47, were significantly increased. These results showed that the JfDREB1A gene may play an important role in the response to cold stress of the Xinjiang wild walnut. This study contributes to our understanding of the molecular mechanism of the Xinjiang wild walnut’s response to low-temperature stress and will be beneficial for developing walnut cultivars with improved cold resistance.

La presente investigación pretendió determinar las variables que influyen en los tipos de memorias colectivas, tipificadas como memoria recuerdo, memoria manipulada y olvido, evocados por 3 lugares vinculados con la dictadura (1973-1990) en Concepción, Chile. Se utilizó un diseño de investigación cuantitativo, descriptivo, con un muestreo no probabilístico por accidente para acceder a 287 participantes de acuerdo a categorías sociodemográficas, orientación política y justificación o no del golpe de Estado en Chile. El instrumento se aplicó en la calle en 3 lugares, 2 considerados de memoria, Memorial de la Universidad de Concepción y el frontis de la Catedral, y un lugar de olvido, el ex cuartel Bahamondes. Se realizaron análisis de Chi cuadrado, Kruskal Wallis, post hoc de Mann Whitney con la corrección de Bonferroni y regresiones logísticas. Predominaron los tipos de memoria recuerdo (47%), en segundo lugar, el olvido (37%) y, finalmente, la memoria manipulada (16%). Las memorias tipo recuerdo se asociaron con ser joven, de orientación política de izquierda ( = 0,29) o no justificar el golpe de Estado (V de Cramer = 0,18). Los lugares de memoria se asociaron más con el tipo de memoria recuerdo, en comparación con el lugar de olvido ( = 0,19). Las memorias recuerdo fueron más frecuentes en la Universidad de Concepción y menos en el ex cuartel Bahamondes. Las conclusiones consideran la relevancia de promover procesos de memoria centrados en el recuerdo ante la amenaza del olvido.

Published: September 2022

Mandibular condyle fractures are the most commonly reported mandible fractures. The incidence of condylar fractures is 25-30% among all mandibular fractures and there are ongoing controversies about their management. The retromandibular transparotid technique is the most frequently employed technique to manage fracture of mandibular condyle. The benefits of this method have been reported to include a shorter working distance between the incision and the fracture site, less morbidity to the facial nerve as it can be identified and retracted under direct vision, cosmetically pleasing outcomes and ease of reduction/fixation of fractures. Nevertheless, surgical treatment of mandibular condyle fractures, can pose danger to facial nerve branches. With respect to condylar fracture surgical treatment, the prevalence of Facial Nerve (FN) injury has been reported to be around 12-48%. This case series reports the surgical and postoperative journey of five patients with subcondylar fracture. The retromandibular transparotid technique was applied in all patients for Open Reduction Internal Fixation (ORIF). Using the House-Brackman facial grading system, FN weakness was assessed. Postoperatively, FN weakness was evident after 24 hours of surgery in two patients. With a mean recovery period of two months, all patients maintained FN function at three months. None presented with persistent paralysis of the facial nerve. Parotid fistulation was not observed in any patient. Inconspicuous scar after six months was observed in four patients. The retromandibular transparotid approach is a safe and effective technique that gives less morbidity to the facial nerve, excellent access, good cosmetic results and patient satisfaction.

Sixteen green gram (Vigna radiata, Fabaceae) genotypes were evaluated under randomized block design (RBD) with three replications for genetic variability for eight characters. The analysis of variance revealed significant differences among genotypes for all the characters. Analysis of variance indicated that experimental material possesses a good amount of variability for all the characters under study. A high magnitude of genotypic coefficient of variance was observed for seed yield per plot, seed yield per hectare, plant height, days to flowering, and test weight while moderate GCV was recorded for the number of seeds per pod, pod length, and days to maturity suggesting the possibility of their improvement by selection. High heritability coupled with high genetic gain as a percent of mean was observed for test weight, seed yield per hector, seed yield per plot, plant height, and days to flowering while high heritability and moderate genetic gain were recorded for days to maturity, pod length and the number of seeds per pod suggesting that these characters were controlled by additive gene action hence, selection may be effective. High heritability coupled with high genetic gain and high GCV has been exhibited by the characters viz., seed yield per hector, seed yield per plot, plant height, test weight, and days to flowering. There is substantial scope for improvement of these characters. Hence emphasis should be given to improving these characteristics in a future breeding program to enhance the seed yield of green gram.

Published: September 2022

Background: There has been a growing concern about the health of people exposed to cement dust.

Objective: This study was aimed at assessing the effect of cement dust on inflammatory markers on cement loaders with different duration of hourly exposure.

Methods: This is a cross-sectional study design conducted in Port Harcourt, Nigeria with 100 male cement workers grouped into 3 groups based on the hourly duration of cement dust exposure. Group 1 (27 subjects) was exposed to 1-5 daily hours; Group 2 (62 subjects), was exposed to 6-10 daily hours, and Group C (11 subjects), was exposed to more than 10 daily hours. The ELISA analysis of C-Reactive protein (CRP), IL-1β, and IL-10 was performed. The data generated were analyzed for mean and standard deviation by ANOVA.

Results: The CRP levels were 5.42 ± 4.72; 6.71 ± 4.96 and 9.04 ± 8.83 in groups 1, 2, and 3 respectively. The p-value was 0.1771 implying no significant difference. The IL-10 levels were 15.72 ± 12.58; 12.23 ± 10.12 and 11.83 ± 8.88 in groups 1, 2, and 3 respectively. The p-value was 0.3421 implying no significant difference. The IL-1β levels were 3.81 ± 1.02; 3.63 ± 1.36 and 3.91 ± 1.21 in groups 1, 2, and 3 respectively. The p-value was 0.7031 implying no significant difference.

Conclusion: The study has shown that hourly changes in exposure to cement dust don’t have an impact on the studied inflammatory markers among cement workers in Port Harcourt.

All‐inorganic perovskite nanocrystals (NCs) have received extensive attention for next‐generation thin film devices due to their excellent optical properties, such as strong light absorption, high carrier mobility, and defect tolerance. However, significant challenges remain to obtain high‐quality perovskite thin films. Herein, a simple but effective post‐treatment by laser irradiation for CsPbBr3 NCs thin films is reported. Laser‐induced secondary crystallization is observed in CsPbBr3 NCs thin films after treatment. In addition, amplified spontaneous emission (ASE) with a low threshold (5.6 µJ cm−2) and a high gain value (743 cm–1) is achieved. Based on optical measurements, it is attributed to the low defect density, reduced Auger recombination, and weak exciton–phonon interactions, which greatly suppress the nonradiative recombination channels. The ASE from the film after treatment has a high characteristic temperature (134 K), showing a stable optical gain performance that maintains its intensity for 35 h at room temperature (and 12 h at 40 °C). Finally, the proof‐of‐concept demonstration of graphic coding is shown. This study deepens the understanding of the optical gain mechanism of CsPbBr3 perovskite films and provides a simple and convenient laser treatment that enables the fabrication of high‐quality CsPbBr3 perovskite thin films.

The correlation between molecular structure and photovoltaic performance is lagging for constructing high‐performance indoor organic photovoltaic (OPV) cells. Herein, this relationship is investigated in depth by employing two medium‐bandgap nonfullerene acceptors (NFAs). The newly synthesized NFA of FTCCBr exhibits a similar bandgap and molecular energy level, but a much stronger dipole moment and larger average electrostatic potential (ESP) compared with ITCC. After blending with the polymer donor PB2, the PB2:ITCC and PB2:FTCCBr blends exhibit favorable bulk‐heterojunction morphologies and the same driving force, but the PB2:FTCCBr blend exhibits a large ESP difference. In OPV cells, the PB2:ITCC‐based device produces a power conversion efficiency (PCE) of 11.0%, whereas the PB2:FTCCBr‐based device gives an excellent PCE of 14.8% with an open‐circuit voltage (VOC) of 1.05 V, which is the highest value among OPV cells with VOC values above 1.0 V. When both acceptor‐based devices work under a 1000 lux of 3000 K light‐emitting diode, the PB2:ITCC‐based 1 cm2 device yields a good PCE of 25.4%; in contrast, the PB2:FTCCBr‐based 1 cm2 device outputs a record PCE of 30.2%. These results suggest that a large ESP offset in photovoltaic materials is important for achieving high‐performance OPV cells.

A compatible and robust electrode–electrolyte interface is favorable in resolving the severe dendritic growth and side reactions of aqueous Zn‐ion batteries toward commercial‐standard lifespan and charging–discharging rate. Herein, a chemical welding strategy through in situ construction of a gel electrolyte that enables Zn‐ion batteries to achieve ultralong life and reversibility is reported. The gel electrolyte is spontaneously formed on the Zn anode surface by redox polymerization with the initiation of Zn metal. The direct participation of the Zn anode in the chemical synthesis of the gel electrolyte brings a well‐bonded and water‐poor electrode–electrolyte interface, which not only alleviates side reactions but also enables preferential (002) Zn deposition. The in situ symmetric cell thus prepared delivers an ultralong lifespan of 5100 h (>212 days), and a hybrid capacitor with the in situ electrolyte runs smoothly over 40 000 cycles at 20 A g−1. Even at an ultrahigh current density of 40 mA cm−2 and capacity of 40 mAh cm−2, the cell still operates stably for 240 h, alongside a high Zn utilization with 87% depth of discharge. The in situ gel electrolyte integrating robust interface and preparation of all‐in‐one cells demonstrate a commercializable path for aqueous Zn‐storage devices.

Hole transport layer‐free, carbon‐based, all‐inorganic CsPbI3 perovskite solar cells (PSCs) have exhibited great potential in photovoltaic applications owing to their low cost and excellent thermal stability. However, the low power conversion efficiency (PCE) hampers its development, mainly due to the existence of defects inside the CsPbI3 film or at TiO2 electron transport layer/CsPbI3 interface. Herein, these issues were addressed through a facile TiO2 post‐treatment strategy using 1‐butyl‐3‐methylimidazole hexafluorophosphate (BMIMPF6) ionic liquid. First, BMIMPF6 can passivate TiO2/CsPbI3 interface defects by forming strong bond between the electron‐rich N atoms and uncoordinated ions. Second, BMIMPF6‐modified TiO2 shows reduced hydrophilicity, inducing decreased heterogeneous nucleation and is favorable for obtaining high‐quality CsPbI3 film. Thirdly, the non‐volatile BMIMPF6 can diffuse to the perovskite film surface during annealing, further passivating defects located at perovskite grain boundaries and surface. Based on this one‐step ionic liquid interface‐to‐bulk modification, the modified device achieves a champion PCE of 15.09%, which is 14% higher than the control device (13.27%). In addition, the modified device also shows enhanced long‐term stability, which remains 96% of initial PCE after 30 days storage in dry air. The work demonstrates the superiority of multifunctional ionic liquid applied to all‐inorganic carbon‐based PSCs, providing a guidance for its commercialization.
The Tuning of Exciton‐Phonon Coupling in Colloidal Nanocrystals by a Dielectric Medium

Here, a thorough study is reported that exposes the influence of surfactants’ dielectric screening on the exciton energy and exciton‐phonon coupling in CdSe and CdSe/CdS colloidal quantum dots and nanoplatelets. The study follows the temperature dependence of the photoluminescence spectrum to monitor thermally activated exciton‐phonon interactions. The dependence of the exciton energy on temperature exhibits an anomalous point at ≈250 K, which coincides with the melting point of surfactant ligands (oleate molecules), an effect that is accompanied by a change in the dielectric constant. Interestingly, this anomalous effect gradually fades away upon increasing the shell thickness in CdSe/CdS derivatives. Furthermore, inspecting the exciton band's full‐width‐at‐half‐maximum (FWHM) dependence on temperature reveals the tuning of the optical phonon frequency when in direct contact with surfactant ligands. However, this effect is replaced by a surplus coupling to the phonon mode of the shell (CdS or CdSeS) when the thickest shell solely isolates the ligand dielectric screening. The study uncovers the impact of the dielectric screening on the optical properties of semiconductor nanocrystals, with an added value in the implementation of those materials in various optoelectronic, quantum, and tagging devices.

Corneal injury can lead to severe vision impairment or even blindness. Although numerous methods are developed to accelerate corneal wound healing, most of them are passive treatments that rarely participate in controlling endogenous cell behaviors or are incompatible with nontransparent bandage. In this work, a wireless‐powered electrical bandage contact lens (EBCL) is developed to generate a localized external electric field to accelerate corneal wound healing and vision recovery. The wireless electrical stimulation circuit employed a flower‐shaped layout design that can be compactly integrated on bandage contact lens without blocking the vision. The role of the external electric field in promoting corneal wound healing is examined in vitro, where the responses of directional migration and corneal cells alignment to the electric field are observed. The RNA sequencing (RNA‐seq) analysis indicates that the electrical stimulation can participate in controlling cell division, proliferation, and migration. Furthermore, the wireless EBCL is demonstrated to accelerate the completed recovery of corneal wounds on rabbits’ eyes by electrical stimulation, while the control group exhibits delayed recovery and obvious corneal defects. As a new generation of intelligent device, the wireless and patient‐friendly EBCL can provide a promising therapeutic strategy for ocular diseases.

Direct contact of membrane molecules and cytokine interactions orchestrate immune homeostasis. However, overcoming the threshold of distance and velocity barriers, and achieving adhesion mediated immune interaction remain difficult. Here, inspired by the natural chemotaxis of regulatory T cells, multifunctionalized FOXP3 genetic engineered extracellular vesicles, termed Foe‐TEVs, are designed, which display with adhesive molecules, regulatory cytokines, and coinhibitory contact molecules involving CTLA‐4 and PD‐1, by limited exogenous gene transduction. Foe‐TEVs effectively adhere to the tubular, endothelial, and glomerular regions of allogeneic injury in the renal allograft, mitigating cell death in situ and chronic fibrosis transition. Remarkably, transcript engineering reverses the tracking velocity of vesicles to a retained phenotype and enhanced arrest coefficient by a factor of 2.16, directly interacting and attenuating excessive allosensitization kinetics in adaptive lymphoid organs. In murine allogeneic transplantation, immune adhesive Foe‐TEVs alleviate pathological responses, restore renal function with well ordered ultrastructure and improved glomerular filtration rate, and prolong the survival period of the recipient from 30.16 to 92.81 days, demonstrating that the delivery of extracellular vesicles, genetically engineered for immune adhesive, is a promising strategy for the treatment of graft rejection.

The targeted transport of nanomedicines is often impeded by various biological events in the body. Viruses can hijack host cells and utilize intracellular transcription and translation biological events to achieve their replication. Inspired by this, a strategy to hijack endogenous products of biological events to assemble into intracellular functional nanoparticles is established. It has been shown that, following tumor vessel destruction therapy, injected cell permeable small molecule drugs bisphosphonate can hijack the hemorrhagic product iron and self‐assemble into peroxidase‐like nanoparticles within tumor‐infiltrating macrophages. Unlike free drugs, the generated intercellular nanoparticles can specifically stress mitochondria, resulting in immune activation of macrophages in vitro and polarizing tumor‐associated macrophages (TAMs) from immunosuppressive to tumoricidal and increasing the recruitment of T cells deep within tumor. The hijacking self‐assembly strategy significantly inhibits tumor growth compared with the treatment of vascular‐disrupting agents alone. Using bisphosphonate to hijack the metabolite associated with hemorrhage, iron, to fabricate functional nanoparticles within specific cells, which may open up new nanotechnology for drug delivery and small molecular drug development.
