Published: July 2023

Chemically-stable metal–organic frameworks (MOFs) featuring interconnected hierarchical pores have proven promising for a remarkable variety of applications. Nevertheless, framework susceptibility to capillary-force-induced pore collapse, especially during water evacuation, has often limited practical applications. Methodologies capable of predicting the relative magnitudes of these forces as functions of pore size, chemical composition of the pore walls, and fluid loading would be valuable for resolution of the pore collapse problem. Here, we report that a molecular simulation approach centering on evacuation-induced nanocavitation within fluids occupying MOF pores can yield the desired physical-force information. The computations can spatially pinpoint evacuation elements responsible for collapse and the chemical basis for mitigation of collapse of modified pores. Experimental isotherms and difference-electron-density measurements of the MOF NU-1000 and four chemical variants validate the computational approach and corroborate predictions regarding relative stability, anomalous sequence of pore-filling, and chemical basis for mitigation of destructive forces.

Published: July 2023

Este estudio considera que el desarrollo de la autorregulación en los estudiantes es necesario para fomentar un aprendizaje significativo e integrador de los conocimientos, sin embargo, muchas veces no se facilitan estos procesos, especialmente cuando se integran los conocimientos teóricos con el ejercicio práctico, por lo que se plantea la necesidad de realizar una estrategia innovadora que estimule la autorregulación en los estudiantes en un contexto clínico simulado, en este caso aplicado a la semiología psiquiátrica. Desde ello, bajo una metodología de estudio exploratorio, con enfoque descriptivo mixto cuantitativo - cualitativo se tiene como objetivo, evaluar las estrategias de autorregulación que utilizan los estudiantes, del pregrado de medicina de Unisanitas, mediante la creación de un ambiente de aprendizaje que integre las competencias y evaluación establecidas en la Unidad Pedagógica Didáctica de depresión. El estudio concluye que, tanto para los estudiantes como para los docentes, el ejercicio fue útil y pertinente toda vez que permitió evidenciar el proceso autorregulatorio. Se reconoce además el hecho que se presentaron algunas discrepancias en las evaluaciones de los docentes y de los estudiantes que están más relacionadas con la falta de confianza de los estudiantes en sus propios conocimientos.

The IL2-inducible T cell kinase, ITK, is differentially expressed in central nervous system metastasis.
Authors: Mamoor Shahan
Published: July 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published RNA-sequencing and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that IL2-inducible T cell kinase, encoded by ITK, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of ITK in CNS metastasis in patients with lung cancer. ITK mRNA was present at decreased quantities in metastasis to the brain in humans with breast cancer. Primary tumor expression of ITK was correlated with recurrence-free survival. Modulation of ITK expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.
Numerical Simulation of Conveying Fine Powders in a Screw Conveyor Using the Discrete Element Method
Authors: Motaln Marko , Lerher Tone
Published: July 2023

Due to their high efficiency and spatial utilization, screw conveyors are widely used in pharmacy, agriculture, and industry. Recently, this has made it a popular research subject in the numerical modelling of the transport of bulk solids. Modelling of granular systems at the level of individual particles is mainly possible due to the use of discrete numerical methods. The most common is the use of the Discrete Element Method (DEM), which is still limited from the point of view of simulations on an industrial scale, as increasing the size of the system also increases the cost of simulation. Certain powders with low density, large angles of repose, poor fluidity, and bad flowability can accumulate during transportation, causing inaccurate and non-uniform movement. Additionally, the friction and impact between the particles can cause wear. To address these issues, the present study utilizes the discrete element method to simulate and analyse powder transportation in an inclined screw conveyor using the commercial software ANSYS-ROCKY. Numerous phenomena that arise while transporting and feeding small-sized or irregularly shaped particles, often present in industrial processes, remain insufficiently investigated. This paper aims to analyse the transportation process of adhesive powders in a screw conveyor, with a focus on evaluating the impact of different screw blade speeds on transport. Multiple simulations were conducted, along with the implementation of an additional wear model, to better understand the transport phenomena and wear. An example was used to demonstrate the impact of screw speed on the wear of the transporter due to the interaction between the material and the structure of the conveyor, power consumption, and performance.
Elite Political Culture and Cosmopolitanism; A case study of Pakistan (2008-2018)
Authors: Ashfaq Mohammad , Roofi Yaseem
Published: July 2023

Each state seeks solidarity and stability by ensuring unity and harmony among the socio-cultural and political segments within its territorial jurisdiction. This study looks at the elite political culture in Pakistan that has been highly criticized for stimulating social complexities by proliferating numerous sorts of political, ethnic, religious/sectarian, or linguistic differences. From 1999 to 2007, when a new class of political elites emerged on the surface of electoral politics as the results of ‘Devolution Plan 2000’, ‘condition of graduation for public representatives’ and ‘17th amendment’ under the slogan of “Pakistan First”; some court verdicts and constitutional engineering during PPP’s third rule upturned respective fruits by bringing back the former elite political culture or traditional elitism as the biggest opposition to populism, political egalitarianism, and democratic liberalism. Therefore, this study conducts a comparative study of PPP and PML(N) regimes (2008-2013 2013-2018 respectively) to find out the correlation between elite political culture and political system that is directly proportional to cosmopolitanism. This comparison assists the study to investigate the contributions of post-18th amendment elite political culture to the problematics of democracy during an addressed decade in Pakistan.

La Charte de l'environnement devant les juges administratif et judiciaire (juillet 2017 - juin 2018)
Authors: Jolivet Simon , Malet-Vigneaux Julie
Published: July 2023

Cette nouvelle chronique couvre la période allant de juillet 2017 à juin 2018. Compte tenu du nombre raisonnable de décisions du Conseil d’État et de la Cour de cassation faisant application de la Charte de l’environnement, les auteurs ont fait le choix d’un traitement exhaustif quoique limité aux juridictions suprêmes des deux ordres de juridiction. Devant le juge administratif, le contentieux porte toujours, majoritairement, sur les articles 5 et 7 de la Charte. Il y a surtout eu, sur la période couverte, des décisions de confirmation et des décisions d’espèce. On n’identifie pas de véritables décisions de principe, sauf sur un aspect précis de l’articulation entre la participation du public et la consultation de certains organismes. Devant le juge judiciaire, le contentieux porte sur les articles 1er, 4 et 5 de la Charte. Deux des trois décisions ont été l’occasion pour les requérants de poser une question préjudicielle, sur la conformité d’une règle de procédure pénale d’abord, et d’une règle d’urbanisme ensuite, au regard de la Charte de l’environnement. La dernière des trois décisions s’inscrit, quant à l’invocation de la Charte, dans la lignée classique de la jurisprudence du juge judiciaire sur l’obligation d’information délivrée au public, même si l’on peut regretter le manque d’audace du juge au regard de l’information particulière en cause.

Published: July 2023

The necessity to generate statistical data of diagnostic parameters of vehicles during their operation is determined. An algorithm for optimizing the supply of spare parts has been developed, taking into account the information and logistics support for the process of replenishing their resource, and an adaptive-controlled approach has been formed in the form of a model of the process of "replacing" the range of spare parts in vehicles. A system-analytical approach to the delivery of spare parts is determined, taking into account the stepwise change in their cost. The developed theoretical provisions will significantly reduce the complexity and time spent in a vehicle idle time.

Authors: W. Kulkarni Ravindra , Tarun Reddy G. , Gajabar Samarin , D. Talikoti Soumya
Published: July 2023

Introduction: Tibial spine fractures are avulsion fractures of the anterior cruciate ligament (ACL). They are more frequent in children than in
adults. Arthroscopic xation methods for such fractures are technically demanding, and their outcomes are compromised due arthrobrosis leading
to knee stiffness, residual ACL laxity causing anterior instability, mal-union, non-union and protruding hardware, all of which may require
subsequent surgery. This is a retrospective study reporting medium-term results of Material And Methods: a series of displaced tibial spine
avulsion fractures in adults treated with arthroscopic ACL reconstruction using a quadrupled Semitendinosus-Gracilis graft. From January 2019 to
June 2021, 9 patients treated using this technique with a minimum follow-up of 2 years were included in this study. There were 7 new fractures and
2 cases were of non-union of tibial spine avulsion fracture previously treated non-operatively. Clinically, all patients had anterior laxity of the knee
pre-operatively. Results: At 6 months all patients had regained full range of movement of the knee, complete functional recovery and ability to
return to work. At the last follow-up at 2 years or beyond, in all patients anterior drawer test, Lachman test and pivot shift test were negative, and all
patients had returned to their pre-injury activity levels. Outcomes as per Modied Lysholm score and also, as per Tapper and Hoover grading were
excellent in 5 cases and good in 4 cases. No patient required any form of reoperation. Arthroscopic ACL reconstruction using a Conclusion:
quadrupled Semitendinosus-Gracilis graft is a satisfactory method of primary treatment for displaced tibial spine avulsion fractures in adults, and
also for non-union of these fractures. Patients thus treated do not have residual ACL laxity or instability, they do not have knee stiffness, and they do
not need any subsequent surgery.

Published: July 2023

Conceptually, Cognitive Behavior Therapy is a pattern of human thought formed from a series of interrelated Stimulus-Cognition-Response processes, in which cognitive processes cause a person to feel and act. Since the CBT technique was carried out at LRKM Mitra Husada, specific measurements have never been carried out to see its effect on changes in the self-esteem of the clients who were given the intervention. This study aims to analyze the effect of cognitive behavioural therapy on the self-esteem of methamphetamine users at LRKM Mitra Husada, Foundation of Mitra Husada, South Sulawesi. This study used the Quasi Experiment method with the research design used being the Pretest-Posttest with Control Group Design, using two groups, namely the intervention group that was given the Cognitive Behavioral Therapy Counseling treatment and the control group that was only given a brochure. The results of this study found that there was an effect of Cognitive Behavioral Therapy (CBT) counselling interventions on the self-esteem of methamphetamine users, where the average pretest result was 1.61 and 2.67 post-test with a significance value of 0.000 (p <0.05 ); There was no effect of giving brochures on the self-esteem of methamphetamine users, where the average pretest result was 1.78 and 1.94 posttest with a significance value of 0.257 (p> 0.05); While the results of the comparative test between the intervention group and the control group found that there was no significant difference in the effect on the control group before and after being given the brochure (p-value 0.257) but found differences in the effect on the intervention group before and after being given CBT counselling (p-value 0.000).

Published: July 2023

There is a growing demand for renewable energy production to contribute to achieving emissions reduction targets in the face of global warming. Indigenous communities across Canada are being called to contribute to the renewable energy sector and participate in collaborative energy developments. While cross-cultural collaborations are not new to the natural resource sector, there is an increasing need for improved practices to collaborate with Indigenous peoples, especially in the renewable energy sector. In collaboration with Eagle Lake First Nation, this research sought to understand the challenges and barriers to engaging in collaborative natural resource management, and determine how to improve cross-cultural engagement processes, with applications in the renewable energy sector. A literature and document review, interviews and community engagements were used to identify challenges and barriers, identify ideal engagement scenarios, and develop recommendations for enhancing cross-cultural engagement processes. This research contributed to developing the community perspectives portion of a community energy plan for Eagle Lake First Nation. In addition, the findings of this research indicate that cross-cultural collaborations in the renewable energy sector presents opportunity to address Reconciliation, while improving the standards and common practices to which engagements are held to. Recommendations for improved engagement practices are provided for First Nations communities, academics, industry and government collaborators.

Published: July 2023

Introducción: los quistes epidermoides son el tercer tumor más común del ángulo pontocerebeloso (APC). Es infrecuente detectar simultáneamente un colesteatoma infiltrativo del oído medio (OM). Caso clínico: paciente de 51 años acude a urgencias por cefalea hemicraneal intensa, pulsátil secundaria a hidrocefalia aguda, requirió ventriculostomía. En la resonancia magnética nuclear (RMN) cerebral contrastada se reporta una masa en el APC sugestivo de quiste epidermoide y simultáneamente un colesteatoma infiltrativo del OM. La paciente fue intervenida primero con resección de colesteatoma del OM; en un segundo tiempo resección del quiste epidermoide del APC por vía translaberíntica. El posoperatorio la evolución clínica fue satisfactoria. Discusión: los quistes epidermoides del APC son histopatológicamente idénticos al colesteatoma del OM y pueden ser secundarios a estos. Conclusión: se debe individualizar el manejo sin descartar la posibilidad de tener las dos enfermedades de manera simultánea.
Trace-based cryptanalysis of cyclotomic $R_{q,0}\times R_q$-PLWE for the non-split case
Authors: Blanco-Chacón Iván , Durán-Díaz Raúl , Nchiwo Rahinatou Yuh Njah , Barbero-Lucas Beatriz
Published: July 2023

We describe a decisional attack against a version of the PLWE problem in
which the samples are taken from a certain proper subring of large dimension of
the cyclotomic ring $\mathbb{F}_q[x]/(\Phi_{p^k}(x))$ with $k>1$ in the case
where $q\equiv 1\pmod{p}$ but $\Phi_{p^k}(x)$ is not totally split over
$\mathbb{F}_q$. Our attack uses the fact that the roots of $\Phi_{p^k}(x)$ over
suitable extensions of $\mathbb{F}_q$ have zero-trace and has overwhelming
success probability as a function of the number of input samples. An
implementation in Maple and some examples of our attack are also provided.

Badminton is a sport that the majority of many enthusiasts. And began to emerge associations of badminton players who were then trained by coaches to then make a profession or their own expertise. In general, shuttlecocks are  removed manually and do not know whether the contents of the slop are exhausted or still filled. Therefore,  automatic shuttlecock  storage devices can make it easier for coaches to provide training to students who are in the association of badminton players. This tool can store  shuttlecocks and remove shuttlecocks automatically which are stored in a dislop containing 12 seeds, the microcontroller used is Arduino Uno, the servo motor is used  to remove the shuttlecock that has a dislop and if the  shuttlecock is not filled then the Servo Motor does not run or open to remove the   shuttlecock  so that the slop must be replenished, then the HC-SR04 Sensor above the slop functions as a device that detects whether  the shuttlecock is still there, then there is the  ISD1820 Sensor which functions as an alarm to notify by voice that  the shuttlecock is up and time to refill, then a tripod as the foundation for  this automatic shuttlecock  storage device. The result of this research test is that 12 shuttlecock seeds  were successful. In this case, it is hoped that this research can help and facilitate coaches in training in a badminton player association on a large scale as well as efficiently knowing the exhaustion of shuttlecocks.

Legal protection of traditional knowledge relating to the field of medicine generally aims to provide commercial utilization of traditional knowledge for the benefit of the national economy. This research aims to conduct an analysis related to legal protection and a comparison of commercialization policies regarding Indonesia’s traditional medicinal knowledge with China. The research method uses a normative juridical approach that focuses on literature study, which is descriptive and analyzed qualitatively. The result of this research is that the legal protection of traditional knowledge related to the field of medicine in Indonesia does not yet have strict regulations and there are no rules regarding the commercialization of traditional medicinal knowledge in Indonesia. This becomes an urgent need because of the lack of adequate rules regarding the protection of traditional medicinal knowledge in Indonesia, causing the operation of law in Indonesia to not work optimally in providing legal protection that is justice, certainty, and usefulness in indigenous peoples as inventors and managers of traditional medicinal knowledge. In contrast to the protection of traditional Chinese medicinal knowledge which already has clear rules regulating the commercialization of the use of traditional medicine. So that now traditional Chinese medicine is used and studied in medical schools around the world.

Kutadgu Bilig de Geçen adaş- Fiili Üzerine
Authors: Gezer Hanife
Published: July 2023

adaş-fiili, Kutadgu Bilig’in sadece Kahire (Mısır) nüshasında, tek bir defa 501 numaralı beyitte geçmektedir. Karahanlı döneminin diğer eserlerinde (Dîvânu Lugâti’t-Türk, Atebetü’l-Hakayık, Türkçe İlk Kur’an Tercümesi-Rylands Nüshası ve Türk İslam Eserleri Müzesi Satır-Arası Kur’an Tercümesi) tespit edilememiştir. Kutadgu Bilig’in Fergana (Nemengan) nüshasında 501 numaralı beyit yoktur. Viyana (Herat) nüshasında ise 501 numaralı beyitte bu kelimenin yerine adaş tut-kullanılmıştır. Arat, adaş-fiilini “arkadaş olmak, ahbap olmak” olarak anlamlandırırken Tezcan’a göre sadece Kahire (Mısır) nüshasına dayanarak bu kelimenin varlığını kabul etmek sakıncalıdır. Bu yüzden bu kelime, Herat (Viyana) nüshasında olduğu gibi adaş tut-şeklinde düzeltilmelidir. Çünkü adaş t ut-Kutadgu Bilig’de birçok kez geçmektedir ve beyit içerisinde de “birini arkadaş edinmek” şeklinde anlamsal olarak uyumlu görünmektedir.Bu çalışmada, önce Eski Türkçe ve Karahanlı dönemi eserlerinde “yakın, arkadaş, akraba; layık olan, uygun olan; aynı isimde olan kişilerden her biri” anlamlarında kullanıldığı tespit edilen adaş kelimesi üzerinde durulacaktır. Daha sonra tut-fiili ile birlikte, adaş-fiilinin yerine kullanılan adaş tut-birleşik fiilinin 501 numaralı beyite kattığı anlam tespit edilecektir. Çalışmanın devamındaadaş-kelimesinin tarihi ve çağdaş Türk lehçelerinde kullanılıp kullanılmadığı; kullanıldı ise hangi anlamlarda kullanıldığı tespit edilecek ve tespit edilen anlamlardan yola çıkılarak 501 numaralı beyit yeniden anlamlandırılacaktır. Son olarak anlamlandırılan adaş-fiilinin etimolojisi üzerinde durulacaktır.

Published: July 2023

Education is critical for the progress and changes of nations across the world. The purpose of the study was to the influence of instructional supervision on students’ academic performance in public secondary schools in Kenya. The article is an extract from a study done in public secondary schools in the Yatta sub-county, Machakos County, Kenya. The study was guided by the instructional leadership model. The researcher adopted a descriptive research design, survey method. The study was conducted among 247 respondents comprising 19 principals and 228 teachers. The study employed stratified sampling techniques and simple random sampling techniques. Data collection was done using questionnaires for principals and teachers. Data were analysed using Statistical Package for Social Sciences (SPSS). The findings, from the principal’s perspective, revealed that there exists a weak positive correlation between the principal’s instructional supervision and students’ academic performance (r = 0.236 p = 0.330). However, from the teacher's perspective, the findings show that there is a weak negative correlation between the principal’s instructional supervision and students’ academic performance (r =- 0.190, p =0.009). Therefore, the study concluded that instructional supervision is crucial, but it must be carried out properly and with the participation of all parties concerned for the best result. It was, thus, suggested that the principals in public secondary schools should enhance instructional supervision by always being actively involved in the day-to-day learning of the institutions and engaging the teacher in planning for the supervision to enhance students’ performance.
Development of students’ responsibility through the principle of engagement
Authors: Butnari Nadejda , Birnaz Nina
Published: July 2023

The engagement presupposes responsible behavior of students in the training process. Determined as a principle, the engagement derives from critical existentialism thinking, an essential dimension of spiritual intelligence. In the training process, the principle of engagement refers to the creation by the teaching staff of educational contexts in which students will be encouraged to get involved, through the possibility of choice, decision-making and assu-ming responsibility in relation to their choices and decisions taken. In this article, a series of specific strategies are reflected, aimed at developing responsibility of students, namely: creating a collaborative learning environment, setting clear and relevant objectives for the student, carrying out tasks in the authentic professional field, providing constructive feedback and involving students in the decision-making process. To achieve these strategies, a general strategy relevant to the didactic context was adapted - the ,,4 What” strategy for the development of critical thinking. This strategy reflects the components through which student responsibility can be developed and assessed. Thus, the correlation between these strategies: the ,,4 What” strategy and the specific strategies generate a friendly didactic design, oriented towards the development of student responsibility in the training process.
Assessment of the knowledge versus the assessment of the competences of public officers with special status and of the carabiniers from the framework of MIA

Knowledge itself is not of much use to civil servants with special status and carabineers within the MIA, whi-le competences, having an essential degree of superiority compared to knowledge, give them the opportunity to prove in practice if they are able to act according to their abilities. From this perspective, the application of the process of evaluating the quality of the staff within the MIA, on the dimension of professional training, is more re-levant and more objective, specifically in relation to skills. Such an approach to evaluation processes will certainly contribute to increasing the level of professional performance of the MIA staff, a fact that will generate sufficient security for the beneficiaries, and citizens’ satisfaction with the quality of the MIA staff will reach expected rates.

Background: The survey aim was to assess COVID-19 pandemic impact on Polish society. Methods: Data were collected based on a special questionnaire in the period of September - October 2021. The questionnaire focused on societal behaviours and quality of life impact of COVID-19 pandemics in Poland. The assessment was performed both online and using paper version of the questionnaire. Results: A total of 290 respondents answered the survey, mostly female (74,8%) young people, aged 18-25 years (50,3%) and inhabitants of big cities (53,8%). Most of the respondents received the vaccine against COVID (79,7%). Within the youngest group the vaccination was received by 80,8% and by 81% in the eldest group. The highest percentage of vaccinated when analysed by place of residence was in a city of more than 500,000 inhabitants (85,3%). As far as to employment status, the percentage of vaccinated among retired and students was high ( 92,3% and 81,3% respectively). Good physical health was declared by 46.2% respondents and very good by 21%. Mental health status in 34.8% of respondents was assessed as good and 15.2% as very good. Mental health was assessed the worst by the youngest respondents and by respondents from cities of 50,000 -150,000 inhabitants, who described the state of psychological health as bad and very bad. Conclusion: For better understanding of COVID-19 pandemics impact on society further studies on broader population are recommended. There is need to increase awareness of COVID -19 disease, vaccines and their impact on society and on fighting with pandemic.

Mastitis poses a major challenge in dairy cattle farming as it leads to production and economic losses. Some mastitis causing bacteria have shown resistance to some antibiotic and the risk factors associated with the antimicrobial resistance (AMR) are not well understood. The current study assessed the prevalence and risk factors associated with occurrence of mastitis in dairy cows kept by small-holder farmers in Githunguri Sub-County, Kenya. Further, susceptibility of the isolated Staphylococcus aureus and Escherichia coli to commonly used antibiotics was evaluated. The study design was cross sectional where 91 milk samples from 40 farms were sampled from two wards in the study area. Structured questionnaires were used to assess risk factors of mastitis. The milk obtained from lactating cows was first subjected to California mastitis test (CMT) and then taken to microbiology laboratory for isolation and identification of Staphylococcus aureus and Escherichia coli using standard bacteriological tests. Antibiotics sensitivity of the isolated bacteria was examined using disc diffusion method. Based on CMT, the overall prevalence of mastitis was 50.5%. The prevalence of mastitis was associated (p<0.05) with hygiene levels, being highest (69.2%) in the dairy cattle whose udder and leg hygiene were dirty. Highest prevalence of mastitis (p<0.05) was found in cows who were not milked regularly (52.4%) compared to those who were milked regularly (47.6%) (p<0.05). Cows which were cleaned using bore hole water had higher prevalence (53.3%) of mastitis compared to those cleaned using tap water (46.7%) (p<0.05). Cows that produced between 21-30 liters of milk per day had the highest prevalence (66.7%) of mastitis, while those producing between over 30 liters milk per day had lower prevalence (25%) (p<0.05). The prevalence of S. aureus and E. coli were 30.8% and 12.1%, respectively. Staphylococcus aureus isolates showed varied resistance to all the tested antibiotics with the highest resistance being against Oxytetracycline (57.7%) and Tetracycline (38.5%) but were sensitive to Vancomycin (100%), Ampicillin (100%), Chloramphenicol (96.2%), Penicillin (92.3%) and Gentamycin (92.3%). All the Escherichia coli isolates were sensitive to Chloramphenicol, Kanamycin, Gentamycin and Oxytetracycline but were resistant to Ampicillin (88.9%) and Vancomycin (88.9%) amongst other antibiotics. In conclusion, half of the sampled cows had mastitis whose risk factors was associated with poor hygiene and irregular milking of the cows. The isolated bacteria showed varied resistance to commonly used antibiotics. To reduce the prevalence of the mastitis and AMR, there is need for extension service workers to train farmers on improved management of the mastitis.

To date, researchers face a huge challenge in synthesizing blue perovskite quantum dots (PQDs) with short‐chain ligands since the short‐chain ligands increase the polarity and decrease solubility in common non‐polar solvents during syntheses. The use of polar solvents to replace non‐polar ones may solve the solution problem, but polar solvents will decompose PQDs. So, the key to successful synthesis of PQDs with short‐chain ligands is to find polar solvents that can dissolve short‐chain ligands well and do not destroy perovskites concurrently. Herein, a room‐temperature synthesis method for deep‐blue CsPbBr3 PQDs with short‐chain ligands is proposed by using eco‐friendly ethyl acetate polar solvent. CsPbBr3 PQDs with an average size of 3.87 nm and a peak wavelength of 454 nm are synthesized with a photoluminescence quantum yield of 48.4%. With an interlayer modification to the hole transport layer, the deep‐blue perovskite light‐emitting diodes realize a maximum external quantum efficiency of 4.39% and half‐lifetime of 4.5 min at a maximum brightness of 72 cd m−2. This work offers a novel eco‐friendly avenue for the preparation of effective PQDs including blue ones, which will accelerate commercialization of PQDs in lighting and HD full‐color displays as well as reduce discharge of solvent pollutants and protect the global environment.
Artificial Siderophores with a Trihydroxamate‐DOTAM Scaffold Deliver Iron and Antibiotic Cargo into the Bacterial Pathogen Escherichia coli

Infections with multidrug‐resistant Gram‐negative bacteria constitute a silent pandemic threat that is increasing globally. A major technical and scientific hurdle hampering the development of efficient antibiotics against Gram‐negative species is the low permeability of their outer membrane that prevents the entry of most small molecules into the cells. This can be overcome by targeting active iron transport systems of the pathogens in a Trojan‐Horse strategy that makes use of drug‐loaded artificial siderophores. While we utilized catechols as iron‐binding motifs in previous work, this study reports the design, synthesis and characterization of siderophores with a DOTAM scaffold that was substituted with three hydroxamate arms allowing for a hexacoordination of iron. Their iron‐chelating capabilities were shown colorimetrically, and the ability of compound 1 to deliver iron into Escherichia coli in a chelation‐specific manner was proven by a growth recovery assay. A covalent siderophore‐ciprofloxacin conjugate exerted antibiotic effects against E. coli, albeit it was less potent than the free drug. The study qualifies artificial DOTAM siderophores with hydroxamate binders as scaffolds for bacterial Trojan Horses. This contribution for honoring my mentor Helmut Schwarz echoes two motifs of my work with him: Hydroxylamin, the topic of my first paper ever, and the fascinating properties of iron ions, studied in the gas phase during my Ph.D. Thesis, became a core subject of our current chemical biology research on antiinfectives.
