Published: October 2023

Character education is one focus and orientation in the education world system.  Therefore, educators should not be apathetic or indifferent to this.  School counselors, as individuals whose role is to educate and teach good character to students, must be more responsible for these good goals.  Thus, a noble goal can be implemented by students in their reel life in the context of culture and society.  The important role of a school counselor lies not only in giving suggestions and suggestions, but also in educating students with full patience and full responsibility for the problems experienced by these students.  On an individual basis, school counselors can provide services, such as individual services, individual planning services, and responsive services.  Character education is one of the educational movements in schools to strengthen student character through harmonization of heart (ethics) and thought (literacy).  Meanwhile, guidance and counseling services are one of the service programs that are fair in implementing programs in schools.  Thus it is hoped that the implementation of strengthening character education through guidance and counseling services will be easy to carry out effectively and efficiently, in order to achieve the goal of starting and optimizing the development of character values ​​that exist in students.

‘Caught between a rock and a hard place’
Authors: Anderberg Andreas
Published: October 2023

The societal approach towards juvenile offenders have, in a Nordic context, focused on care and treatment rather than punishment. As juvenile delinquency is seen as an ever-increasing problem, the social law efforts have been deemed insufficient by politicians and more emphasis has been placed on measures of criminal justice. Furthermore, procedural regulations have been subject to reform proposals in a repressive direction. At the same time, children’s rights have been strengthened for example by the UN Convention of the Rights of the Child becoming Swedish law.The legal consequences for juvenile offenders are thus a complex field of tension, in the middle of legal areas with often diametrically opposed goals and strategies. The question has also been raised whether juvenile offenders should be dealt with, within an entirely separate system.The purpose of this essay is to illustrate the conflict area and show a development in the legislature on juvenile offenders. Also, the question whether the increasingly repressive measures are compatible with children’s (human) rights is raised. The essay is based on Swedish conditions, but since Swedish legal debate in recent years have been strongly influenced by (sometimes questioned) Danish reforms such as e.g. lowering the age of criminal responsibility and introducing special Youth Crime Boards, Denmark will serve as a natural point of comparison.
Erhvervsskolelæreres håndtering af sameksisterende krav om øget fastholdelse og et højt fagligt niveau i erhvervsuddannelserne
Authors: Jonasson Charlotte , Nielsen Klaus
Published: October 2023

I de seneste år har mange OECD-landes, her- under Danmarks, politiske mål været at sikre at endnu flere unge får en ungdomsuddannelse. Dette politiske mål er langt fra entydigt, for på den ene side ønskes en øget gennemførel- sesprocent og på den anden side, samtidig, en forbedring af den uddannelsesmæssige kvalitet. Artiklens formål er at belyse, hvordan lærere på erhvervsuddannelserne håndterer disse sameksisterende uddannelsespolitiske krav. Et empirisk studie baseret på et etårigt feltarbejde på en dansk teknisk skole viser, at de politiske krav om fastholdelse af eleverne og et højt erhvervsrettet kvalifikationsniveau kan føre til, at lærerne udvikler forskellige pæ- dagogiske strategier, så som en aktiv ‘omsorgs- tilgang’, en passiv ‘vente til det her forløb er ovre’ tilgang, en aktiv ‘selektionstilgang’ samt en passiv ‘vent og se, om de selv falder fra’ tilgang. De forskellige pædagogiske strategier er udviklet gennem social forhandling ledere, elever og lærerne imellem − og medfører flere pædagogiske dilemmaer.
Les besoins et les défis de l’évaluation des compétences linguistiques des enseignants et des enseignantes d’immersion française et de français langue seconde en Alberta
Authors: ElAtia Samira , Essiomle Komla , Rousseau Pierre , Corsi Elissa , Mechkouri Kaoutar
Published: October 2023

Les enseignants et les enseignantes d’immersion française (IF) et de français langue seconde (FLS) doivent être des modèles langagiers pour les élèves. Les directions d’école et les cadres des conseils scolaires ont l’obligation de s’assurer, à travers un processus d’évaluation, que le personnel enseignant embauché dispose de compétences linguistiques suffisantes pour fournir un cadre d’apprentissage bilingue aux élèves et qu’il s’engage à les améliorer constamment. À travers une enquête administrée auprès de 48 professionnels et professionnelles d’IF et de FLS, suivie de quatre entrevues semi-dirigées menées auprès des membres des équipes de direction d’école, nous avons analysé les perspectives d’éducateurs et d’éducatrices de l’Alberta sur les besoins et les défis liés à l’évaluation du français. Les résultats indiquent qu’il n’existe pas de processus d’évaluation linguistique uniforme durant l’embauche du personnel enseignant et que la planification des activités de perfectionnement linguistique dépend souvent de la taille du conseil scolaire, de l’emplacement de l’école, des ressources disponibles et de l’insécurité linguistique du personnel enseignant.
MEDIJSKOM PISMENOŠĆU PROTIV POSTNOVINARSTVA
Authors: Išaretović Slavica
Published: October 2023

Počevši od prvih medija, koji danas već imaju odredicu stari (tradicionalni), koji su učinili riječi i slike dostupnim kozumentima, kao novine i film, uticaj medija je edvidentan. U našem vremenu sve ono što nije objavlјeno ni na jednoj društvenoj mreži kao da nismo ni proživjeli i time objašnjavamo lјudsku potrebu da se svaki događaj iz života i lično mišljenje podijeli na Instagramu, Fejsu (facebooku), Tviteru (Twitter), Tik Toku. Novi mediji uklanjaju realnost, stvarajući hiperrealnost, koja nema ništa zajedničko sa stvarnim svijetom, osim nas, koji kako to objasni Bodrijar, bježimo od „pustinje realnog svijeta“ u svijet hiperrealnosti, zahvalјujući kompjuterskom, medijskom i tehnološkom iskustvu. Postajemo entitet zatrovan medijskim uticajem. Medijska pismenost postaje neophodna vještina da bismo preživjeli doba postnovinarstva i postistine i odoljeli negativnim uticajima medija.
UTJECAJ AUDIO - VIZUELNE INDUSTRIJE NA UREĐIVAČKU POLITIKU TELEVIZIJSKOG MEDIJA
Authors: Mesić Emin , Mecan Zlatko
Published: October 2023

Savremeni mediji danas su toliko integrisani u audio - vizuelnu industriju tako da nema nijednog aspekta života čovjeka u kojem nije izražena potreba za sadržajima koji se proizvode van kontrole medijskih programskih i uređivačkih politika. Još je američki sociolog medijske kulture Marshall McLuhan početkom 1960-ih godina prošlog vijeka proročanski nagovjestio globalnu ekspanziju audio - vizuelne kulture, ne sluteći, možda, ni sam, da će ona kao ranije i film postati jedan od najmoćnijih generatora razvoja moderne svjetske industrije. Na početku ere nove audio - vizuelne kulture, televizijski medij isključivo je zavisio od vlastite produkcije. Međutim, danas više od 75 odsto ukupno proizvedenog televizijskog programa u svijetu se odnosi na TV produkciju nezavisnih produkcijskih kompanija. I u Bosni i Hercegovini javni emiteri, kao i komercijalne i nezavisne televizijske stanice, pretežno emituju sadržaje audio - vizuelne industrije.
АТЕНТАТ КАО ПОЈАВНИ ОБЛИК ТЕРОРИЗМА –МОТИВ И ПСИХОЛОШКИ ЛИК САВРЕМЕНИХ АТЕНТАТОРА И МАСОВНИХ УБИЦА
Authors: Симовић Слободан , Радуловић Душан
Published: October 2023

Иако је Србија постала земља са највише убијених владара и државника у Европи у последњих 190 година, атентат као терористички акт није само српска традиција, већ историја људских колектива. Ипак, и међу бројним атентатима постоји одређена категоризација: на пример, атентати у Европи су извршени пре свега из јасно де- финисаних политичких мотива, док су у Америци дело психопата (барем се тако представљају), Србија, наравно, има свој клише: бизнис – полиција, односно мафијашко- политичка варијанта у виду „машине за чекање“, или евентуално, камиона са песком. Ипак, најзанимљивији ликови су амерички усамљеници, и то не само зато што им је Холивуд посветио стотине филмова. Да ли су несвесни пиони великих завера или не, за њихов циљ није важно, јер је политичка мржња само изговор за такве убице. Психо- лабилни убице су мање-више слични: сви они имају свог моћника којег треба елимини- сати да би послали поруку целом свету. Пре него што су убице Ал Каиде поништиле све листе приоритета, стручњаци ФБИ-ја су се највише плашили ових соло убица јер се једноставно појављују ниоткуда. „Соло убице“, непримећени актери друштвених збивања теже слави и као најлакши начин да „додирну звезде“ проналазе убијање. Што више лешева, то су познатији.

AMERIČKI KONFEDERALIZAM - PUT OD PRIVIDA KONFEDERACIJE KA ISTINSKOJ FEDERACIJI
Authors: Petrović Željko
Published: October 2023

Prve države su bile centralistički i unitarno uređene, sa jednim, jedinstvenim centrom državnog i političkog rukovođenja i odlučivanja. Takve unitarne i centralističke države bile su bliže i samom pojmu države. Tek krajem 18. vijeka pojavljuje se i federalno uređena država koja je odgovarala potrebi osavremenjivanja i demokratizovanja vlasti kao i idejnim i političkim tendencijama i doktrinama koje su obilježile revolucionarno doba u tadašnjoj Evropi i Americi. Međutim SAD u svom nastajanju bile su konfederacija, koja je predstavljala odraz stanja u kolonijama koje su se borile za nezavisnost od Britanske imperije. Ta konfederacija pokazala je niz slabosti tako da će SAD ići u pravcu centralizacije odnosno stvaranja federalno uređene države. Konfederacija daje veću autonomiju njenim članicama koje su praktično države u savezu u koji su dobrovoljno pristupile. Težnja država Juga SAD ka većoj autonomiji odnosno nezavisnosti, te sukob oko pitanja robovolasništva, odnosno ekonomski faktori, ponovo će odvesti SAD na put stvaranja konfederacije u toku Američkog građanskog rata. U SAD nastala su dva fronta, federalistički i konfederalistički koji su smatrali da će jedno ili drugo uređenje voditi boljem funkcionisanju države, odnosno državne zajednice.
ŽENSKE V ZNANOSTI IN TEHNOLOGIJI

Published: October 2023

Zadnjih dvajset let si družba intenzivno prizadeva za enakopravnost spolov in tako skrbi tudi za ozaveščanje ter spodbujanje žensk, ki so zaposlene na znanstvenem in tehnološkem področju (tj. v poklicih, ki jih uvrščamo v t. i. STEM − science, technology, engineering, mathematics). Ideja, da sta inženirstvo in tehnologija pretežno moški področji, postaja vse bolj oddaljena realnost, saj vemo, da je odstotek zastopanosti žensk v tej sferi predvsem v Sloveniji relativno visok. V raziskovalnem delu prispevek tako predstavi podatke o zastopanosti žensk na tehniškem oz. naravoslovnem področju med letoma 2018 in 2020 v Sloveniji, Nemčiji in Evropski uniji. Povzema posledice večje participacije žensk v znanosti in razloge, zakaj se ženske niso odločile oz. se redkeje odločajo za te poklice. Prispevek prav tako razišče projekte in dejavnosti v Sloveniji, ki ozaveščajo dekleta o teh poklicih in prispevajo k povečanju tega deleža.
Superficies in foreign countries: history and modernity.
Authors: Sekretaryov Roman Viktorovich
Published: October 2023

The institution of superficiality originated in Ancient Rome and exists in various models today in the legal systems of many countries, which proves the high value and universality of this legal structure. He was analyzed as classics of the law of the past centuries, and there are modern leading civilists. However, as our research has shown, not all the achievements of foreign specialists in the field of civil law are available to domestic theorists. This is explained both by the significant amount of accumulated information itself and by the difficulty of choosing it when preparing specific scientific publications. The author understands the monumentality of the raised problem and sought to focus on those aspects of it that other Russian scientists do not always pay attention to in their publications. The novelty of the undertaken research is the introduction into the domestic scientific circulation of modern English-language publications on the legal regulation of superficies in the countries of Eastern and Central Europe and Japan. The relevance of the article is seen in an attempt to use the examples of foreign legislation to assess the prospects for using this concept to improve Russian legislation. In addition to the formal legal method, which is traditionally the main tool for the author, the comparative legal method, typology and classification were used in the preparation of the article. The object of the study is legal relations mediated by the institute of superficies. The subject of the study is the legislative acts of modern foreign states and the norms of law governing super-official relations in earlier historical periods.

In this study two types of samples of spectrally pure graphite, compacted and coated with glassy carbon, were analyzed with liquid scintillation spectrometry, scanning electron microscopy (SEM) and X-ray diffractometry (XRD). “Space” sample has been sent in outer space on the surface of ISS for 28 months. “Space” sample is compared with “reference” sample, made of the same material, but stored on Earth for the same period.

Radiation environment data were collected using R3DR2-Lyulin instrument, located in the outer space very close to the samples, in the same module of ISS. The effect of cosmic radiation leads to slight increase of 14C content, detected by liquid scintillation spectrometry.

SEM and thermal test using XRD did not show any noticeable changes in terms of structure and phase composition. This confirms the high degree of reliability of this material under significantly milder operating conditions in Earth orbit.

Endometriosis is a debilitating disease that affects up to 15% of women worldwide. Delayed diagnosis, lack of noninvasive biomarker and unexplained pathogenesis are key problems for specialists and patients alike. MiRNAs are a class of noncoding RNAs that regulate myriad of cellular functions. These gene expression regulators may prove to be attractive biomarkers with diagnostic and prognostic value for endometriosis.

Tissue samples were collected from the participants enrolled in the study during laparoscopy (patients) and hysteroscopy (control group). After RNA isolation (miRNeasy MiniKit, Qiagen) based on the disease stage, three pools – each containing 15 RNA samples, were constructed: 1) early stage endometriosis, 2) late stage endometriosis, and 3) healthy controls. Each pool sample was subjected to reverse transcription via miScript II RT Kit, Qiagen to obtain cDNA. SYBR Green based Real-time PCR assay was used to determine the expression profile of 84 miRNAs (Human miFinder miRNA PCR Array, Qiagen).

We detected 32 differently expressed miRNAs between early stage endometriosis and control group, and 51 differently expressed miRNAs between advanced stage endometriosis and control group. Three miRNAs were differentially expressed with more than 10-fold change in the early stage group and thn miRNAs showed more than 10-fold change in the advanced stages group. The three miRNAs with the highest fold change in the expression levels in both case groups were nominated as potential biomarkers for endometriosis. The results of the analysis of their target genes supports the role of deregulation of apoptosis, angiogenesis, epithelial-mesenchymal transition, and various other cellular signalling pathways in endometriosis development.
RUNX1 facilitates heart failure progression through regulating TGF-β-induced cardiac remodeling
Authors: Qi Peng , Zhai Qian , Zhang Xiquan
Published: October 2023

Background

Heart failure is caused by acute or chronic cardiovascular diseases with limited treatments and unclear pathogenesis. Therefore, it is urgent to explore new therapeutic targets and reveal new pathogenesis for heart failure.

Methods

We carried out heart failure animal model by transverse aortic arch constriction (TAC) in mice. The left ventricular internal diameter diastole (LVIDd), left ventricular internal diameter systole (LVIDs), and ejection fraction (EF) value were detected using ultrasound and myocardial fibrosis was evaluated by Masson stain assay. Cell apoptosis in myocardial tissues were detected by TUNEL immunofluorescence stain. Signal pathway analysis was performed by dual-luciferase reporter assay and western blot.

Results

Our results showed that inhibition of RUNX1 led to remission of cardiac enlargement induced by TAC in mice. Inhibition of RUNX1 also caused raise of EF and FS value under TAC-induced condition. Besides, RUNX1 inhibition mice showed decreased myocardial fibrosis area under TAC-induced condition. RUNX1 inhibition caused decrease of apoptotic cell rate in myocardial tissues under TAC. Interestingly, we found that RUNX1 could promote the activation of TGF-β/Smads in dual-luciferase reporter assay.

Interpretation

We illustrated that RUNX1 could be considered as a new regulator of myocardial remodeling by activating TGF-β/Smads signaling. Based on this, we concluded that RUNX1 may be developed as a new therapeutic target against heart failure in the future. In addition, this study also provide a new insight for the etiological study on heart failure.
Evaluating Corrosion Resistance of Metal Materials in Fire Productsvia Saltwater Spray Test Under Various Experimental Conditions
Authors: Kim Jong-Sang , Han Yong-Taek
Published: October 2023

The brine concentration and salt spray time of KS D 9502, a saltwater spray test commonly used in Korea, were used to experimentally confirm the corrosion in iron, copper and stainless steel, and the degree of corrosion in fire extinguishers, automatic diffusion extinguishers, and residential automatic extinguishers. The results of the KS D 9502 brine spray test confirmed that there was little difference between iron and stainless under all test conditions, and that the results of the salt water test for copper were nearly identical to those of 5 wt% and 240 h (10 cycles). Unlike the two previous sets of conditions, the test results obtained at 5 wt% and 120 h of saltwater of the raw material showed very few visual (qualitative) and weight (quantitative) changes in corrosion, rendering these conditions unsuitable for the saltwater spray test. The saltwater spray tests in the fire extinguisher, automatic diffusion fire extinguisher, and residential automatic fire extinguisher showed that the results obtained at 5 wt% salt water and 240 h (10 cycles) and those obtained at 20 wt%, 240 h were nearly identical. These experimental studies show that the saltwater spray test of KS D 9502 is a variable in the corrosion resistance test, in which the time of the saltwater spray test is more important than the saltwater concentration.
A Study on dFMEA-based Fire Risk Assessment of Lithium-ion Secondary Battery Testing Cells
Authors: Kim Jong Gu , Kim Hyeong Gi
Published: October 2023

In this study, Design Failure Mode and Effects Analysis (dFMEA) was performed to evaluate the fire risk of lithium-ion secondary battery testing cells used during the research and development stage. dFMEA was used for the failure risk analysis, risk assessment, and risk priority analysis of the anode, cathode, separator, electrolyte, and cell design of the testing cell. In addition, the evaluation criteria, including severity, occurrence, and detection, was reorganized into three categories and optimized for the testing cell application. Based on the failure risk analysis, a total of 11 causes of failure were identified. In particular, explosion and thermal runaway were predicted when a nickel-cobalt-manganese (NCM)-based anode material with a high nickel content was used, the separator had a high thermal contraction rate and low tensile strength characteristics, and there were errors in the electrolyte composition optimization. This cause of failure was classified as a moderate risk with a high fire risk by the risk priority analysis. Therefore, at the research and development stage, it is critical to evaluate the mutual reactivity and preliminary physical properties of battery materials and to construct safety equipment to reduce fire damage.

Agricultural Assistants’ Perceptions towards their Roles: A Case Study from Southern Province of Zambia
Authors: Chikalipa Emmanuel
Published: October 2023

Studies have been conducted in Africa to assess camp extension officers’ perception towards their roles, however, little is known about agricultural assistants' perceptions towards their roles, as per government job description in Zambia. It was a cross-sectional qualitative study undertaken from January to July 2023, in which questionnaires were administered to 100 agricultural assistants (AAs) to assess the AAs perception of their roles. The collected quantitative data was analysed by using the Statistical Package for Social Sciences (SPSS) computer program. The findings show that most of the interviewed AAs perceived their roles namely; training, technical support, and performance management as important. However, AAs are faced with challenges such as low camp extension officer to farmers ratio; inadequate support to extension service delivery; conflicting methodologies in extension service delivery between public and private sector players; poor extension planning, reporting, and feedback culture; and inadequate in-service and refresher training for AAs. Based on these findings, it is recommended that there is a need to work out all aspects that affect the performance of the AAs' mandated roles. To considerably address the challenges of AAs in Zambia, the study does, however, encourage the government to recruit additional AAs, organise in-service and refresher training for AAs to improve their knowledge and skills, and adequate support to extension delivery. This would assist AAs in carrying out their mandated responsibilities and, ultimately, improve the delivery of extension services for improving agricultural performance across the country.

Greenhouse cultivation is spreading as it offers the grower a higher net yield per hectare from high quality crops as it reduces the likelihood of yield decline. The greenhouse is kept at 30-40˚ C with a relative humidity of up to 70%, which could be ideal for plant growth, but is not suitable for workers. Heat exposure in the workplace causes discomfort to the human while working.   So, the main goal of conducting this research is to address the extent of heat stress and associated health issues for the greenhouse workers. The study was planned for 2022 in the Raipur district of Chhattisgarh. Prior to the assessment, a questionnaire survey was conducted among 50 greenhouse workers to learn perceptions of heat exposure, heat-related health issues and awareness of heat management. To get the heat exposure air temperature, wet bulb temperature, relative humidity, black globe temperature were measured on hourly basis. The wet bulb globe temperature (WBGT) was measured along with greenhouse workers' physiological parameters to quantify heat exposure. With the help of clock diagram showing Humidex Index (HI). The time period at which farmers most likely to suffer from heat stress was estimated. It was reported that in April, May, June, July, August and September WBGT index reaches varied between 30 and 34°C. According to ISO 7243 the recommended WBGT for comfortable workplace should be less than  31°C. Further study was conducted to get physiological responses of the 21 farm workers in three different type of greenhouses and at three time slots. It resulted that heart rate was maximum i.e. 156 bpm in walk in tunnel at 11 am to 1 pm. The average working heart rate was 20 % more than the open field condition. Hence, the study will help to make the strategies to reduce the exposure of heat stress conditions to the greenhouse workers.

The low toughness under the tension of cement and concrete materials has been a long‐standing issue for decades and it has become increasingly urgent to address in modern society due to the growing demand for the development of high‐performance and sustainable constructions. Manipulating calcium silicate hydrate (C‐S‐H), the main hydration product of Portland cement, which determines the mechanical properties of cementitious materials, is an attractive method for improving their toughness following a bottom‐up approach. Inspired by the microstructure of nacre, a high energy absorption C‐S‐H‐based composite with a highly ordered structure is fabricated by a designed ternary building block, in which exfoliated montmorillonite provides a template for the nucleation and growth of C‐S‐H generating the “brick”, and polyvinyl alcohol acts as a “mortar” binding all the building blocks together. With the hierarchical toughening strategy explored here, the obtained C‐S‐H composite achieves a remarkable energy absorption of 16.2 ± 2.6 MJ m−3, which surprisingly outperforms the ultra‐high toughness cementitious materials by a factor of 20–60 and is even higher than that of natural nacre and other nacre‐like composites. These findings not only provide valuable insights into enhancing the toughness of cementitious materials but also open possibilities for broadening potential applications of C‐S‐H.

The development of bifunctional electrocatalysts suitable for a wide pH range and seawater splitting under simulated industrial electrolysis conditions is expected to advance practical applications of clean hydrogen energy. Here, the study reports a built‐in electric field approach to assemble heterogeneous Ru nanoclusters (Ru NCs) anchored in P,O co‐doped NiFe layered double hydroxide bifunctional electrocatalysts (Ru NCs/P,O‐NiFe LDH) for overall water splitting. It is revealed that the BEF ensures electron enrichment via unidirectional electron transfer from P,O‐NiFe LDH to Ru nanoclusters due to the difference in the corresponding Fermi levels. The optimized Ru NCs/P,O‐NiFe LDH/NF shows excellent electrocatalytic activity toward hydrogen evolution reaction, oxygen evolution reaction, and overall water splitting in a wide pH range, as well as simulated seawater electrolysis under industry‐relevant conditions. The long‐term catalyst stability under high currents and industrial process temperatures is also demonstrated. Density functional theory calculations further confirm that the active sites at the BEF interface effectively reduce the energy barrier of water electrolysis, thereby facilitating the electrocatalytic processes.
Thermochromic Photonic Crystal Paper with Integrated Multilayer Structure and Fast Thermal Response: A Waterproof and Mechanically Stable Material for Structural‐Colored Thermal Printing
Authors: Zhang Xin , Yin Tian , Ge Jianping
Published: October 2023

Thermochromic photonic crystals are promising materials for thermal printing due to their unfaded colors under chemical/illuminated environments and the absence of toxic chemicals. However, the slow thermochromic response, the multistep printing procedures, the use of inks or developing liquids, and the requirement of expensive parts in printers limit their applications. Here, a thermochromic polyurethane/hydrophobic‐SiO2 photonic crystal/paraffin (PU/HPO‐SiO2‐PC/Para) film with an integrated multilayer structure is fabricated for all‐solid‐state and single‐step thermal printing that is fully compatible with commercial printers. The fast thermochromic response in milliseconds enables high‐resolution and grayscale printing as the paraffin infiltration and the color change can be finely controlled in a microscale range. The integrated and hydrophobic multilayer structure renders the thermochromic film good stability in daily liquids, which addresses the long‐existing concern of print fading. Meanwhile, the integrated multilayer structure also enhances the mechanical stability when it is deposited on fibrous paper so that people can fold, cut, or staple the thermal papers, and make notes confidently in practical usage.

Compared to widely adopted low‐dimensional/three‐dimensional (LD/3D) heterostructure, functional organic cation based surface termination on perovskite can not only realize advantage of defect passivation but also prevent potential disadvantage of the heterostructure induced intercalation into 3D perovskite. However, it is still very challenging to controllably construct surface termination on organic–inorganic hybrid perovskite because the functional organic cations’ substitution reaction is easy to form LD/3D heterostructure. Here, we report using a novel benzyltrimethylammonium (BTA) functional cation with rational designed steric hindrance to effectively surface terminate onto methylammonium lead triiodide (MAPbI3) perovskite, which is composed of the most unstable MA cations. The BTA cation is difficult to form a specific 1.5‐dimensional perovskite of BTA4Pb3I10 by cation substitution with MA cation, which then provides a wide processing window (around 10 minutes) for surface terminating on MAPbI3 films. Moreover, the BTAI surface terminated BTAI‐MAPbI3 shows better passivation effect than BTA4Pb3I10‐MAPbI3 heterojunction. Finally, BTAI surface terminated solar cell (0.085 cm2) and mini‐module (11.52 cm2) obtained the efficiencies of 22.03 % and 18.57 %, which are among the highest efficiencies for MAPbI3 based ones.

DNA nanostructures have played an important role in the development of novel drug delivery systems. Herein, we report a DNA origami‐based CRISPR/Cas9 gene editing system for efficient gene therapy in vivo. In our design, a PAM‐rich region precisely organized on the surface of DNA origami can easily recruit and load sgRNA/Cas9 complex by PAM‐guided assembly and pre‐designed DNA/RNA hybridization. After loading the sgRNA/Cas9 complex, the DNA origami can be further rolled up by the locking strands with a disulfide bond. With the incorporation of DNA aptamer and influenza hemagglutinin (HA) peptide, the cargo‐loaded DNA origami can realize the targeted delivery and effective endosomal escape. After reduction by GSH, the opened DNA origami can release the sgRNA/Cas9 complex by RNase H cleavage to achieve a pronounced gene editing of a tumor‐associated gene for gene therapy in vivo. This rationally developed DNA origami‐based gene editing system presents a new avenue for the development of gene therapy.

The difunctionalization of alkenes—a process that installs two functional groups in a single operation and transforms chemical feedstocks into value‐added products—is one of the most appealing synthetic methods in contemporary chemistry. However, the introduction of two distinct functional groups via two readily accessible nucleophiles remains a formidable challenge. Existing intermolecular alkene azidocyanation methods, which primarily focus on aryl alkenes and rely on stoichiometric chemical oxidants. We report herein an unprecedented electrochemical strategy for alkene azidocyanation that is compatible with both alkyl and aryl alkenes. This is achieved by harnessing the finely‐tuned anodic electron transfer and the strategic selection of copper/ligand complexes. The reactions of aryl alkenes were rendered enantioselective by employing a chiral ligand. Crucially, the mild conditions and well‐regulated electrochemical process assure exceptional tolerance for various functional groups and substrate compatibility with both terminal and internal alkyl alkenes.

Accidentally, it was found that triphenylamine (TPA) from commercial sources shows ultralong yellow‐green room temperature phosphorescence (RTP) like commercial carbazole, which however disappears for lab‐synthesized TPA with high purity. Herein, we for the first time identify the impurity types that cause RTP of commercial TPA, which are two N, N‐diphenyl‐naphthylamine isomers. Due to similar molecular polarity and very trace amount (≈0.8 ‰, molar ratio), these naphthyl substituted impurities can be easily overlooked. We further show that even at an extremely low amount (1000000 : 1, mass ratio) of impurities, RTP emission is still generated, attributed to the triplet‐to‐triplet energy transfer mechanism. Notably, this doping strategy is also applicable to the triphenylphosphine and benzophenone host systems, of which strong RTP emission can be activated by simply doping the corresponding naphthyl substituted analogues into them. This work therefore provides a general and efficient host/guest strategy toward high performance and diverse organic RTP materials.
