Published: December 2022

Reconstruction of flexor tendons of the hand injuries is performed under general or regional anesthesia and tourniquet, in general. During the Covid-19 pandemic period the insufficiency of anesthesiologists created the need to find alternative methods of anesthesia with similar results of the existing ones. Wide awake, local anaesthetic, no-tourniquet technique (WALANT) started to be more popular, and based on the advantages (low cost, no tourniquet, no access of anaesthetic support, intraoperative collaboration to control active motion of flexor tendon reparation) gradually appeared to be a safe technique. Combination of lidocaine and adrenaline allows to ensure local anesthesia and at the same time vasoconstriction. The aim of this study is to estimate the evidence of effectiveness and secure of the WALANT technique in a case series from our hand reconstruction unit according to patient’s satisfaction, complications, and functional outcomes. Material & Method: During the period from April 2021 to September 2022, 34 patients with traumatic lesion of flexor tendon of the hand were treated with tenorrhaphy under WALANT procedure. The flexor tendon zone of traumatic injury was I,II,III, and T1,T2,T3. All patients were operated within 24 hours from the injury and were able to be discharged on the same day. The majority of the operations were performed in a second operative theatre and all performed without anaesthetic support. Results: Overall, Visual Analogue Scores were 0/10, mean rate of patient’s satisfaction was very satisfied in 82.3%, while mean Quick DASH score was 1.38. There were no cases with peri-postoperative complication during the WALANT technique. In all cases there was no need to administrate phentolamine as antidote to adrenaline vasoconstriction or other procedure of anesthesia. Conclusions: WALANT procedure is a safe method in which you can control pain and blood loss from the combination of lidocaine and adrenaline. The absence of tourniquet avoid the intra- postoperative discomfort of the patient, while intraoperative collaboration of the patient offers immediate restoration of active motion of flexor tendon and avoid postoperative complications from tenorrhaphy. Furthermore, patients̓ satisfaction continues to exist high and rate of postoperative complication nonentity.

Published: December 2022

Garbage is one of the big problems in society.lack of awareness of throwing garbage in its place worsen the situation. Waste processing has also become more difficult because waste is not sorted. lack of knowledge of sorting waste does not make matters better. To deal with this problem, the government launched a bank sampah program to reduce waste problems. But garbage banks don't accept all types of waste. The waste bank only accepts waste that can be recycled. Therefore a game was created to teach sorting garbage and not to litter. It was made with a sound sensor to give a unique impression in the game.  The game development is designed with a reward and punishment system to tell players if they do the right thing.  After the game is finished, tests are conducted on several elementary school children and the results are that EE, PE, and HM have an influence on the BI variable.
REFUGE AND INTEGRATION FROM THE PERSPECTIVE OF THE TORAH. CONSIDERATIONS FROM AN ANCIENT PERSPECTIVE ON THE MODERN PHENOMENON OF IMMIGRATION
Authors: FRIEDMANN Luciana
Published: December 2022

Over the millennia, people have been forced, countless times, to leave their homeland and settle in other lands. As in the 21st century, the possible reasons were the same - the economic, political situation, discrimination, the difficulty of integrating or, simply, the fact that leaving was the only way out. The Jewish diaspora has known many stages, some recorded in the Bible - Torah - Old Testament. Others, such as the expulsion of the Jews from the Iberian Peninsula, led to the peregrinations of the Jews in various corners of the world. The present work aimed to put into the perspective of ancient Jewish religious writings the way in which the idea of refuge is treated today.
The migration phenomenon is considered by some to be characteristic of the modern era, being regulated by national and international legislation. The way in which Judaism treated this subject - cities of refuge, moral obligation towards the one who asks for help, “Dina de malkuta dina” - the law according to which the law of the residence prevails over the religious law - represents an interesting model to follow, but also similar in certain aspects, with the current legislation.
The present work aimed to highlight some good practices, less known, which facilitated the integration in various societies in certain situations.

I researched the way in which the treatment of refugees changed over time, considering, however, that Judaism continued to be faithful, until today, to some religious principles that, in fact, regulate basic interpersonal relations.

Authors: HRISTOVA Snezhana , MILEVA Ivona , BUNDALESKA Elena
Published: December 2022

Nowadays, businesses are required to create added value and difference. In recent years, the synergy perspective grew into one of the main concerns of corporate and strategic management. It creates a new path for change in the way of designing the business strategy, characterized by the collaboration mindset embedded in the overall strategic thinking context. This paper investigates the perceptions and practices of the IT managers with regards to the potential of synergy strategies. It aims to explore the growing importance of synergies between all elements, stakeholders, and processes in the organization, with a particular emphasis on the connections which include cooperation, interaction and working together to realize accepted purposes and strategic goals. The primary data were obtained through a survey carried out in the IT businesses in North Macedonia and evaluated by using the descriptive statistics. The key findings indicate that synergy strategies can create added value on the company’s sustained competitive advantage. The results showed that the synergy strategy appears to be a good managerial practice to be fostered on the organizational level to produce greater results. As the synergy effects seem to be a widespread practice, but rarely discussed topic within the IT sector in North Macedonia, the research will attempt to provide a theoretical contribution to the academic community, but also to help local managers to identify and coordinate opportunities for integrating the sinergy in their business strategy. Apart from the main research focus, our aim expands further to making a broader contribution to the theories of strategy and organization.

RELEVANSI PEMIKIRAN IMAM SYAFI’I TENTANG MAFQUD TERHADAP PERCERAIAN GHAIB (STUDI DI KASUS DI PENGADILAN AGAMA JOMBANG)
Authors: Khotim Ahmad
Published: December 2022

Dalam pemikiran Imam Syafi’i ada yang berpendapat bahwa apabila suami atau istri yang mafqud harus menunggu selama empat tahun dan menurut Undang-Undang serta Kompilasi Hukum Islam adalah harus menunggu dengan jangka waktu selama 2 tahun. Jangka waktu antara kedua pendapat ini sangat lama jika dikomparasikan. Ini karena canggihnya sistem transportasi dan informasi yang hadir pada era modern ini memberikan kesempatan yang cepat untuk mengetahui keberadaan si mafqud. Berbeda dengan waktu dulu yang yang masih belum mengenal sistem transportasi dan informasi. Maka di sini di lihat manakah yang lebih relevan untuk diikuti antara pemikiran Imam Syafi’i atau Undang-Undang dan Kompilasi Hukum Islam. Dalam tulisan ini meneliti tentang Relevansi Pemikiran Imam Syafi’i tentang Mafqud Terhadap Perceraian Ghaib Studi Kasus di Pengadilan Agama Jombang. Penelitian ini bertujuan untuk mengetahui pendapat Imam Syafi’i tentang mafqud dan putusan Pengadilan Agama Jombang mengenai perceraian mafqud. Dalam penelitian ini, penulis menggunakan metode penelitian deskriptif yaitu penelitian yang berusaha menggambarkan dan menganalisis permasalahan sedetail mungkin. Jenis penelitian yang digunakan adalah bersifat penelitian kepustakaan (library research) dengan menelusuri teori-teori yang terdapat di perpustakaan dan lapangan. Hasil penelitian menunjukkan tidak ada satu dalil Al-Quran dan hadits yang menyebut batas waktu penetapan masa orang hilang, yang terdapat hanyalah pendapat sahabat yakni Umar bin Al-Khatab. Tetapi pendapat Umar hanyalah untuk istri yang kehilangan suami. Selain itu, dapat diketahui juga konsekuensi dari mafqud yang bisa terjadi terhadap orang sekeliling atau ahli warisnya dan ia menjadi satu tuntutan untuk menyelesaikannya. Karena hukum bersifat dinamis akan berubah dari waktu ke waktu mengikuti era perubahan zaman.

The Effects of Corporate and Individual Income Taxes on A gricultural Development in Nigeria
Authors: Omodero Cordelia Onyinyechi
Published: December 2022

Research background: The contribution of Nigerian companies and personal income taxes to agricultural development must be assessed. Throughout the years, comparable studies have focused on general economic growth rather than a specific facet of the national economy. Agriculture ensures food safety, job creation, and industrialization, which is why government revenue should be reassigned to improve agricultural production.

Purpose: The particular goal of this study is to investigate the extent to which corporate and individual income taxes influence agricultural growth in Nigeria.

Research methodology: The data set for dependent and independent variables are collected from the Central Bank of Nigeria Statistical Bulletin and OECD accordingly. The reliant variable in the study is government investment in agriculture, while the independent variables are companies and individual income taxes. The data collected for this study is analyzed using a multiple regression analytical approach.

Result: At the 1% level of significance, the results of the multiple regression analysis show that personal income tax has a significant and positive influence on agricultural development. Corporate tax does not have a significant impact on agriculture. This outcome could be attributed to the lack of government attention to agriculture as well as other Nigerian factors such as corruption and tax evasion. The research suggests that tax revenue should be collected more effectively and efficiently, and that tax resources be directed more toward sustainable agriculture.

Novelty: This study is unique in that it is the first to examine the usefulness and application of corporation and individual income taxes to agricultural finance.
An Evaluation of Circular Economy Development in the Baltic States
Authors: Jakubelskas Ugnius , Skvarciany Viktorija
Published: December 2022

Research background: The fact that all resources are not infinite and the needs of society are steadily increasing, new ways of producing, consuming and waste disposal should be adopted. A circular economy as a modern alternative to a linear economy became one of the priorities of the European Union in order to create a modern, resource-efficient and competitive system.

Purpose: The purpose of this article is to present the concept of a circular economy and the justification of its implementation based on a literature review. The article focuses on determining the factors of a circular economy and evaluating its importance in the Baltic States. In other words, the main aim of the article is to highlight the factors of a circular economy and assess its significance.

Research methodology: A panel regression analysis was used in order to evaluate which indicator of the selected circular economy factors is the most important.

Results: The survey reveals that waste electrical and electronic equipment has the most significant potential for increased circular material use rate in the Baltic States. All electrical and electronic equipment should be designed so that it would be possible to repair and reuse it to extend the product life cycle and reduce the carbon footprint. Reducing greenhouse gas emissions in conjunction with increasing the usage of renewable energy could increase resource productivity and domestic material consumption (DMC) and ensure Baltic States’ independence in the energy sector through offshore wind farms that have the region’s most considerable potential.

Novelty: There is a lack of studies conducted in the Baltic States focused on circular economy development using panel data. Most of the previous studies were focused on the European Union as a whole or individual countries. This study presents a deeper analysis of circular economy development in the Baltic States.

Authors: Yatsiv Ihor , Cherevko Heorhiy
Published: December 2022

Research background: Assessment of the positive and negative aspects of the concentration of agricultural production in Ukraine, including in the form of agricultural holdings, is very dynamic due to the dynamic macroeconomic conditions of doing business here.

Purpose: The goal of the article is to present the results of research and an assessment of the consequences of the concentration of agricultural production in Ukraine through indicators of changes in the size and efficiency of agricultural enterprises.

Research methodology: The research methodology is based on the general dialectic approach and includes the following methods: induction, monographic, graphical, grouping, analysis of dynamic series, and formalization of calculation algorithms.

Results: Regularities of influence of the sizes of the agrarian enterprises on the efficiency of their functioning are revealed. The study showed that the concentration of production creates a number of strengths in agricultural production in the country as a whole which helps to solve certain social problems. However, the concentration of agricultural production does not increase the economic efficiency of enterprises.

Novelty: The assessment of the consequences of large agricultural enterprises in Ukraine and the activities of agricultural holding companies has been differentiated. Previously made conclusions of other researchers on the consequences of the concentration in agricultural production has been clarified.
Online Auctions End Time and its Impact on Sales Success – Analysis of the Odds Ratio on a Selected Central European Market
Authors: Zakonnik Łukasz , Czerwonka Piotr , Zajdel Radosław
Published: December 2022

Research background: E-commerce is developing rapidly, especially during the Covid19 pandemic. This fact can benefit individuals who want to sell their already used goods. Importantly, for sellers, it is not always a priority to get the highest price, but sometimes it is simply effective to get rid of the goods at a satisfactory price.

Purpose: The aim of this article is to analyze the impact of the broadly understood time of the end of the online auction on the success or failure of a sale.

Research methodology: In the study, the raw odds ratio was used for the effect of a single variable. Next, the impact of specific variables within the set of risk factors was determined using the logistic regression.

Results: Auctions ending in the evening were found to be more than 150% more likely to be successful, while night hours reduced the chance of success by 50%. The day’s most favorable for sales are Monday and Tuesday, the opposite pattern was observed for Wednesday, Thursday and Friday. An interesting relationship was found for the second half of the month, which increased the possibility of selling the goods by over 20%.

Novelty: In the literature there are almost none that would focus on the analysis of the possibility of ending the auction with a sale (i.e. success) in the context of the auction end time on the Central European market. This issue is usually discussed on the side and has not been analyzed comprehensively – this paper is a step forward in this direction.
Patient Prosthesis Mismatch in SAVR: How Avoidable is It in the ‘Real World’?
Authors: Mushtaq Amir , Ali Montasir H , Ionescu Adrian
Published: December 2022

We set out to assess whether the preoperative prediction of patient-prosthesis mismatch by an algorithm popularised by Pibarot et al. is accurate compared to PPMM defined as AVA <0.85 cm2/m2 (‘any PPMM’) or as AVA <0.65cm2/m2 (‘severe’ PPMM).

We studied 37 patients (16 female), with mean age 72.3 +/− 8.4 years, who had unplanned SAVR during 2019. By echo, 17 (19.7%) patients had severe PPMM (mean AVA (SD) = 0.55 (0.04) cm2). For the 0.85cm2/m2 cut-off, 14/37 patients (37%) had PPMM (mean AVA (SD) 0.70 (0.15) cm2. By the Pibarot algorithm, 21 (56.7%) patients were predicted to have any PPMM and 10 (27%) severe PPMM.

The preoperative algorithm for the avoidance of patient prosthetic mismatch does not accurately identify patients who have postoperative PPMM as defined by echocardiography. Further refinements of the algorithm seem necessary before it can be used widely in clinical practice.

Social factors such as social support, integration, and belonging to the community are positive resources against adverse events and living conditions. This study at examining the influence of social support on depression among elderly people in Serbia. The research was done according to the type of cross-sectional study, a mass survey of a random, representative stratified two-stage sample of the population of Serbia in 2013, which was conducted by the Ministry of Health of the Republic of Serbia. The target population consisted of 3540 respondents aged 65 and over. The Patient Health Questionnaire-8 (PHQ-8) was used to evaluate the presence of depressive symptoms and the social support score from the questionnaire Oslo-3 scale of social support. The relations between depression symptoms and social support were examined with univariate logistic regression analyses. In the univariate regression model, social support stood out as a strong predictor of depression. People with weak social support are three and a half times more likely (OR = 3.45) to have depression compared to those with strong social support. Men with small social support were more likely to have depression (OR = 5.08) than women (OR = 3.41). These results indicate the urgency of addressing depression as a public health priority to reduce the burden and disability and improve the overall health of the elderly population.

Published: December 2022

Objective: The advancement in percutaneous transluminal coronary angioplasty (PTCA) has led to it becoming the predominant mode of revascularization. Post PTCA adverse events in the form of stent thrombosis, recurrent ischemia, unplanned revascularization, recurrent hospitalization etc. result in morbidity as well as mortality. Biomarkers predicting such outcomes can be useful in initiating more aggressive medical therapy and greater modification of risk factors. This study was undertaken to study the predictive significance of periprocedural plasma fibrinogen levels for coronary stenting outcomes.

Methods: 80 patients diagnosed as either chronic stable angina (CSA), unstable angina (UA), Non ST Elevation Myocardial Infarction (NSTEMI) or late presentation ST Elevation Myocardial Infarction (STEMI) undergoing planned PTCA were included in study. Patients were evaluated for clinical history, electrocardiogram (ECG), two dimensional echocardiography (2D-echo) and cardiac biomarkers (Creatinine Phosphokinase-MB isomer (CK-MB) and Troponin I). Serum fibrinogen level was measured 24 hours prior to PTCA along with routine pre-operative investigations; and also 24 hours after coronary stenting. Patients were followed for six months. Outcome measure was taken to be freedom from cardiac related adverse events, including rehospitalization, unplanned repeat revascularization, definite stent thrombosis, transient ischemic attack, stroke and all-cause mortality.

Results:  Fibrinogen level ≥393 mg/dL, 24 hours prior to percutaneous transluminal coronary angioplasty, was associated with higher major adverse cardiac and cerebrovascular events (MACCE) rates (60%) as compared to those with fibrinogen level <393 mg/dL (3.6%).  Fibrinogen level ≥427 mg/dL 24 hours after percutaneous transluminal coronary angioplasty, was associated with higher major adverse cardiac and cerebrovascular events rates (65%) as compared to those with fibrinogen level <427 mg/dL (6.7%).

Conclusion: The current study demonstrates that higher baseline and post procedural fibrinogen, is an independent predictor of 6 months major adverse cardiac and cerebrovascular events after elective percutaneous coronary intervention.

Key words:  Coronary stent outcomes, major adverse cardiac and cerebrovascular events, plasma fibrinogen, stent diameter

Authors: YILMAZ Oktay , MİSLİ UÇMAZ Çılga
Published: December 2022

Robert Crease’in bilim insanlarına “Tüm zamanların en güzel bilimsel deneyleri nelerdir?” diye sorduğu anket çalışmasında, Foucault sarkacı bilimde en güzel ilk on deney içinde yerini alır. Fizikte geometrik faz konusu ele alındığında Hannay açısı hesaplanırken Foucault sarkacı önemli bir örnektir. Newton’nun ikinci hareket yasası eylemsiz (ivmesiz) referans sisteminde geçerlidir. Yerküre ivmeli bir sistem olduğu için Newton’nun ikinci hareket yasası Coriolis, Euler ve merkezkaç gibi hayali kuvvetler eklenerek düzeltilir. Bu makalede Foucault sarkacının çalışma ilkesi, sarkaç denklemleri, başlangıç değerlerini içeren çözümleri, Foucault’nun 1851 yılındaki deneyinde kullandığı sayısal değerlerle, açık ve anlaşılır bir şekilde sunulmak istenmiştir. Bununla birlikte Hannay açısı açık bir şekilde hesaplanmıştır. Foucault, Paris’te bulunan görkemli Pantheon kilisesinin kubbesine meşhur sarkacını asarak, ilk defa 1851 yılında sarkacın salınım düzleminin yavaş yavaş dönüş hareketini gözleyerek, yerkürenin kendi ekseni etrafında döndüğünü ve yerkürenin bir eylemsiz sistem olmadığını ispatladı. Böylece, gökyüzü gözlemine ve teleskoba ihtiyaç duymadan yerkürenin dönüşü hissedilir ve görünür hale geldi. Penceresi olmayan bir odanın içinde bile yerkürenin dönüşü ispatlanabilir ve dikkatli ölçüm yapılarak sarkacın asılı bulunduğu bölgenin enlem açısı ölçülebilir. Foucault sarkaçları dünyanın pek çok yerinde sergilenir ve keşfin yapıldığı 1851 yılından bu yana gösteriler yapılarak kutlanır. İtalyan bir düşünür ve yazar olan Umberto Eco’nun “Foucault Sarkacı” adını verdiği bir romanında da konusu geçmektedir.

Many local film industries in developing economies are struggling to compete with foreign film hits. Surprisingly, despite the high exposure from imported films, the Indonesian film industry has maintained a robust domestic market in the last decade. This study aims to gather insights from this phenomenon by examining the key factors that distinguish the profiles of non-successful and successful local films at the Indonesian box office. The analysis was conducted based on the characteristics of 225 local  films from 2017 to 2018. We employed a recent method to generate such profiles, namely the tree-based comparative analysis, which uses a machine learning model to augment the cross-case comparisons from a large pool of data. The study result suggests that the success of local films is mainly driven by the actor's popularity and the presence of foreign movie hits at the box office. Besides, we also found that the distinction between moderately successful and highly successful local films predominantly lies in story familiarity, suggesting the efficacy of the "brand extension" strategy in the Indonesian film industry. The study concludes by offering some managerial insights for producers and distributors to deliver successful films at the box office.

Selling Out for a Song: “Artist Abuse” and Saving Creatives from Servitude and Economic Disadvantage in the Entertainment Industry
Authors: Morris Rick G.
Published: December 2022

Artists drive the entertainment industry with their creative work, and in some cases, there are protections for artists when it comes to their work, wealth, and autonomy. However, the area of contracts called “private law,” under which artists’ contracts fall, is lightly regulated in comparison to other employment agreements. Artists, often at the beginning of their careers, are signed to long-term contracts that take advantage of them and do not provide adequate compensation. Artists might be locked into contractual arrangements that they cannot free themselves from. Sometimes, they are directly cheated. And much of this comes from people they trust, including their managers, agents, and even family members and friends. Artists have complained publicly for years and have taken what actions they could to improve their situations. This article examines various forms of contractual “artist abuse” in the entertainment industry. Next, this article looks at the lifecycle of these arrangements and artists’ means of working to free themselves, including self-help practices and the use of applicable law. Finally, in light of the risks of bad contracts, this article visits current discussions for reform and suggests practical revisions to the contractual and negotiating processes that could help reduce the conflict and human suffering caused by over-reach, power differences, and entrenched practices in any industry where personal services contracts are used.
A Diazaborine-Based Fluorescent Probe Tracks Endogenously Produced Peroxynitrite in Live Cells
Authors: Haggett Jack , Domaille Dylan
Published: December 2022

We present the synthesis, properties, and imaging applications of Peroxynitrite Probe-1 (PNP-1), a novel organoboron-based probe for selective peroxynitrite (ONOO-) imaging in live cells. PNP-1 features a diazaborine-based reaction motif that provides excellent discrimination between H2O2 and ONOO-, solving a persistent challenge of organoboron-based fluorescent probes for oxidative metabolite imaging. We demonstrate the utility of PNP-1 to detect endogenously produced ONOO- in live RAW 264.7 macrophages, with probe selectivity confirmed by inhibition of NADPH oxidases and nitric oxide synthase, the requisite enzy-matic machinery for ONOO- production. Beyond the direct application of PNP-1, our results reveal that diazaborines are a modular reaction motif for selective ONOO- reactivity, positioning them for incorporation into other ONOO--specific chemical biology tools.
Laplace inverted pulsed EPR relaxation to study contact between active material and carbon black in Li-organic battery cathodes

The addition of conductive additives during electrode fabrication is standard practice to mitigate a low intrinsic electronic conductivity of most cathode materials used in Li-ion batteries.To ensure an optimal conduction pathway, these conductive additives, which generally consist of carbon particles, need to be in good contact with the active compounds. Herein, we demonstrate how a combination of pulsed electron paramagnetic resonance (EPR) relaxometry and inverse Laplace transform (ILT) can be used to study such contact. The investigated system consists of PTMA (poly(2,2,6,6–tetramethylpiperidinyloxy–4–ylmethacrylate)) monomer radicals, which is a commonly used redox unit in organic radical batteries (ORB), mixed at different ratios with Super P carbon black (CB) as the conductive additive. Inversion recovery data were acquired to determine longitudinal relaxation time constant distributions.It was observed that not only the position and relative amplitude, but also the number of relaxation modes varies as the composition of PTMA monomer and CB is changed, thereby justifying the use of ILT instead of fitting with a predetermined number of components.A hypothesis for the origin of different relaxation modes was devised. It suggests that the electrode composition may locally affect the quality of electronic contact between the active material and carbon black.
Selective Photocatalytic Reduction of Acetylene to Ethylene Powered by a Cobalt-Porphyrin Metal–Organic Framework

The production of polymer-grade ethylene requires the purification of the ethylene feed from acetylene contaminant. Accomplishing this task by state-of-the-art thermal hydrogenation requires high temperature, an external feed of H2 gas, and noble metal catalysts, and is not only expensive and energy-intensive but also prone to over-hydrogenation to ethane. This paper reports the photocatalytic semihydrogenation of acetylene to ethylene using the metal-organic framework (MOF) Co-PCN-222. Under pure acetylene atmosphere the system achieves an overall conversion of 1.6 mol g-1 Co, and remains catalytically active for one week. Under a mixed acetylene/ethylene atmosphere (1 vol.% acetylene, 30 vol.% ethylene, the industrially relevant conditions), the system achieves nearly 100% conversion of acetylene after 87 hours with >99.9% ethylene selectivity over ethane. The cobalt active species is contained within the Zr-based Co-PCN-222 framework and the heterogeneous nature of the MOF lends advantages over the homogeneous catalyst, namely facile recyclability and increased longevity. These features also offer substantial advantages over current thermocatalytic hydrogenation technologies with respect to selectivity and sustainability. While MOFs have been pursued academically for the physical separation of acetylene and ethylene, this is the first demonstration of the potential MOFs have as catalysts for the selective, photocatalytic conversion of acetylene to ethylene.

Biological encapsulants, such as viral capsids and ferritin protein cages, use many identical subunits to tile the surface of a polyhedron. Inspired by these natural systems, synthetic chemists have prepared an extensive series of artificial nanocages, with well-defined shapes and cavities. Rational control over the self-assembly of discrete, nanometre-scale, hollow coordination cages composed of simple components still poses considerable challenges as a result of the entropic costs associated with binding many subunits together, difficulties in the error-correction processes associated with assembly, and increasing surface energy as their size grows. Here we demonstrate the construction of a family of nanocages of increasing size derived from a single simple pentatopic pyrrole-based subcomponent. Reasoned shifts in the preferred coordination number of the metal ions employed, along with the denticity and steric hindrance of the ligands, enabled the generation of progressively larger cages, incorporating more subunits. These structural changes of the cages through these ‘mutations’ are reminiscent of differences in the folding of proteins caused by minor variations in their amino acid sequences; understanding how they impact capsule structure and thus cavity size may help to elucidate construction principles for still larger, more complex and functional capsules, capable of binding and carrying large biomolecules as cargoes.
