Active Machine Learning for Chemical Engineers: a Bright Future Lies Ahead!
Authors: Ureel Yannick , Dobbelaere Maarten R. , Ouyang Yi , De Ras Kevin , Sabbe Maarten K. , Marin Guy B. , Van Geem Kevin M.
Published: October 2022

By combining machine learning with design of experiments, so-called active machine learning, more efficient and cheaper research can be conducted. Machine learning algorithms are more flexible, and are better at investigating the processes spanning all length scales of chemical engineering. While the active machine learning algorithms are maturing, its applications are lacking behind. Three types of challenges faced by active machine learning are identified and ways to overcome them are discussed: the convincing of the experimental researcher, the flexibility of data creation, and the robustness of the active machine learning algorithms. A bright future lies ahead for active machine learning in chemical engineering thanks to increasing automation and more efficient algorithms to drive novel discoveries.
Deep learning pipeline for statistical quantification of amorphous two-dimensional materials
Authors: Leist Christopher , He Meng , Liu Xue , Kaiser Ute , Qi Haoyuan
Published: October 2022

Aberration-corrected transmission electron microscopy enables imaging of two-dimensional (2D) materials with atomic resolution. However, dissecting the short-range-ordered structures in radiation-sensitive and amorphous 2D materials remains a significant challenge due to low atomic contrast and laborious manual evaluation. Here, we imaged carbon-based 2D materials with strong contrast, which is enabled by chromatic and spherical aberration correction at low acceleration voltage. By constructing a deep learning pipeline, atomic registry in amorphous 2D materials can be precisely determined, providing access to a full spectrum of quantitative datasets, including bond length/angle distribution, pair distribution function, and real-space polygon mapping. Accurate segmentation of micropores and surface contamination, together with robustness against background inhomogeneity, guaranteed the quantification validity in complex experimental images. The automated image analysis provides quantitative metrics with high efficiency and throughput, which may bring new insights into the structural understanding of short-range-ordered structures. In addition, the convolutional neural network can be readily generalized to crystalline materials, allowing for automatic defect identification and strain mapping.
Syntheses of (+)-Antrodiellin B, (−)-Hypnophilin and (−)-Coriolin and Strained 5/5/5 and 5/6/4 Skeletons via [5+2+1]/Epoxidation/Transannular Radical Cyclization
Authors: Yu Zhi-Xiang , Wang Lu-Ning , Huang Zhiqiang
Published: October 2022

Nature produces many molecules (so-called natural products) containing compact scaffolds such as cis-anti-cis-configurated 5/5/5 and 5/6/4 tricycles. But other molecules with more strained structures, such as trans-anti-cis-configurated 5/5/5 tricycles have been rarely found in nature. Accessing all these natural and non-natural molecules will strengthen the power of organic synthesis and benefit many fields such as medicinal chemistry, chemical biology that are heavily dependent on the available quantity of new/important molecules. Herein, we report a new strategy to synthesize molecules with cis-anti-cis-configurated 5/5/5 tricycles, 5/6/4 tricycles and trans-anti-cis-configurated 5/5/5 tricyclic skeletons by [5+2+1]/epoxidation/transannular radical cyclization strategy, where challenging cis and trans 5/8 bicycles with both ene and carbonyl functional groups were accessed by Rh-catalyzed [5+2+1] reaction of ene-vinylcyclopropanes and carbon monoxide, followed by epoxidation of the double bond in the 5/8 bicycles, and Ti(III) mediated epoxide/carbonyl cyclization to build target skeletons. This strategy was further applied to the first total synthesis of (+)-antrodiellin B, the asymmetric total synthesis of (−)-hypnophilin and formal synthesis of (−)-coriolin with cis-anti-cis configurated 5/5/5 skeleton (both hypnophilin and coriolin are highly oxidized and have significant biological activities).
Comprehensive Structure-Activity Relationship Studies of Cepafungin Enabled by Biocatalytic C–H Oxidations
Authors: Amatuni Alexander , Shuster Anton , Abegg Daniel , Adibekian Alexander , Renata Hans
Published: October 2022

The cepafungins are a class of highly potent and selective eukaryotic proteasome inhibitor natural products with potential to treat refractory multiple myeloma and other cancers. The structure-activity relationship of the cepafungins is not fully understood. This account chronicles the development of a chemoenzymatic approach to cepafungin I. A failed initial route involving derivatization of pipecolic acid prompted us to examine the biosynthetic pathway for the production of 4-hydroxylysine, which culminated in the development of a 9-step synthesis of cepafungin I. An alkyne-tagged analog enabled chemoproteomic studies of cepafungin and comparison of its effects on global protein expression in human multiple myeloma cells to the clinical drug bortezomib. A preliminary series of analogs elucidated critical determinants of potency in proteasome inhibition. Herein we report the chemoenzymatic syntheses of 13 additional analogs of cepafungin I guided by a proteasome-bound crystal structure, 5 of which are more potent than the natural product. Enzymatic strategies enabled the facile synthesis of oxidized amino acids in the macrocycle warhead as well as the tail fragment. Additional analogs were prepared by chemical methods to further explore the SAR at other regions of the scaffold. These studies reveal the criticality of the macrocyclic L-lysine oxidation regio-/stereochemistry introduced in the natural product biosynthesis relative to other possible lysine oxidation patterns found in nature. The lead analog was found to have seven-fold greater proteasome b5 subunit inhibitory activity and has been evaluated against several multiple myeloma and mantle cell lymphoma cell lines in comparison to the clinical drug bortezomib.
Promoter-poison partnership protects platinum performance in coked cluster catalysts

Published: October 2022

Deactivation via coking due to a lack of selectivity is a persistent problem for the longevity of Pt-based dehydrogenation catalysts. Ge as a promoter improves the exper- imental selectivity and stability of subnano Pt clusters. The origin of this improvement is self-limiting coking, to form a Pt4GeC2 cluster which is more stable and selective than the bare Pt4Ge cluster. In this paper we compare the dehydrogenation abilities of Pt4 and Pt4C2 with and Pt4Ge and Pt4GeC2 with DFT calculations in order to explore the origin of self-limiting coking in the presence of Ge. The unique stability of Pt4GeC2 is attributed to electron donation from Ge to the C2 atoms. This prevents the coke from drawing electrons from the Pt, which is the origin of deactivation via coking. Thus, we identify an electronic mechanism for coke deactivation and then use an electronically driven doping strategy to improve catalyst longevity. This differs from the common perception of coke deactivating via steric blocking of active sites.Furthermore, Pt4C2 and Pt4GeC2 show differences in kinetic accessibility of different isomers, which brings us into a new paradigm of sub-ensembles of isomers, where the dominant active sites are determined by kinetic stability under reaction conditions, rather than Boltzmann populations.
Tinjauan Yuridis Terhadap Pengalihan Objek Jaminan Fidusia Tanpa Persetujuan Kreditur
Authors: Syafiuddin Muhammad Hafidz , Arsin Lukman Fransiscus Xaverius
Published: October 2022

This study discusses the credit agreement of banking and non-banking financial institutions requiring the existence of a collateral that must be done first in order to be able to make credit. A loan agreement with a fiduciary guarantee is the procedure chosen to adapt to the growth of the business world and the needs of the community. This research explains about the transfer of fiduciary collateral objects without the collector's approval and also about the application of legal protection in the practice of fiduciary engagements to the collectors. The borrower must have good intentions to properly maintain the collateral. About Fiduciary collateral, borrowers are not allowed to exchange, loan or lease to other parties for goods that are used as objects of fiduciary collateral, if the collecting party does not agree. It is legally valid that the fiduciary giver has taken an action that diverts the object of the fiduciary collateral being carried out, if the party receiving the fiduciary does not give written consent. The practice of legal protection for creditors has not yet reached the maximum point, this is because there are still many factors that put emphasis on creditors when they want to execute collateral objects themselves.

Penelitian ini membahas mengenai perjanjian kredit lembaga keuangan perbankan maupun non perbankan mewajibkan dengan adanya suatu agunan yang harus dilakukan terlebih dahulu agar dapat melakukan kredit. Perikatan pinjaman dengan agunan fidusia adalah prosedur yang dipilih untuk beradaptasi dengan pertumbuhan dunia usaha serta keperluan masyarakat. Riset ini menjelaskan tentang pengalihan objek agunan fidusia tanpa persetujuan penagih dan juga mengenai penerapan proteksi hukum dalam praktik perikatan fidusia kepada pihak penagih. Peminjam harus memiliki tujuan yang baik untuk menjaga barang agunan dengan baik. Tentang jaminan fidusia peminjam tidak diperbolehkan menukar, mengagunkan maupun mengontrakkan kepada pihak lain terhadap barang yang dijadikan objek agunan fidusia, apabila pihak penagih tidak setuju. Hal tersebut secara sah bahwa pemberi fidusia telah melakukan tindakan yang mengalihkan objek agunan fidusia yang dikerjakan, apabila pihak yang menerima fidusia tidak memberikan persetujuan tertulis. Untuk praktik perlindungan hukum pada kreditur belum mencapai titik maksimal, hal tersebut dikarenakan masih banyak faktor yang menjadikan titik berat kepada kreditur saat ia ingin mengeksekusi sendiri benda jaminan.

 
Penyitaan Berbasis Properti Sebagai Upaya Pengembalian Kerugian Keuangan Negara Dalam Tindak Pidana Korupsi
Authors: Ilmi Musfiratul , Muchtar Syamsuddin , Ilyas Amir
Published: October 2022

This study aims to analyze the application of property-based returns on state financial losses. The research method used is empirical by using primary and secondary data sources. Data was collected by interviewing a special criminal prosecutor and analyzing three court decisions. This study, not only discusses the return of state losses but also discusses solutions so that the execution of recovering state losses can be maximized. This research is based on the theory of economic analysis of law. This study resulted in three points, the first is that property-based confiscation are only used for proof. Second, as the basis for recovering state financial losses, the model used is value-based confiscation. Third, the return of state financial losses is still an option that can be replaced with a substitute imprisonment. Supposedly, corruption convicts should not be given a choice of alternative prisons but can be replaced with sanctions in the form of social work which can be calculated as the value of state losses. In addition, the draft asset return law must be ratified by referring to UNCAC 2003 so that there are rules governing the return of assets.

Penelitian ini bertujuan untuk menganalisis penerapan pengembalian kerugian keuangan negara dengan berbasis properti. Metode penelitian yang digunakan yaitu empiris dengan menggunakan sumber data primer maupuan sekunder. Pengumpulan data dilakukan dengan wawancara terhadap seorang jaksa tindak pidana khusus dan menganalisis tiga putusan pengadilan. Penelitian ini, tidak hanya membahas mengenai pengembalian kerugian negara saja tetapi juga membahas terkait solusi sehingga eksekusi pengembalian kerugian negara dapat dimaksimalkan, untuk itu penelitian ini berpatokan pada teori economic analysis of law. Penelitian ini menghasilkan tiga poin, pertama adalah penyitaan berbasis properti hanya digunakan untuk pembuktian. Kedua, sebagai dasar pengembalian kerugian keuangan negara, model yang digunakan adalah penyitaan berbasis nilai. Ketiga yaitu pengembalian kerugian keuangan negara masih menjadi suatu pilihan yang dapat diganti dengan pidana penjara pengganti. Seharusnya, terpidana korupsi tidak diberi pilihan penjara penggani tetapi dapat diganti dengan sanksi berupa pekerjaan sosial yang dapat dihitung sebagai nilai dari kerugian negara. Selain itu, rancangan undang-undang pengembalian aset harus disahkan dengan berpedoman pada UNCAC 2003 agar ada aturan yang memayungi pengembalian aset.

Exergy investigation of home air conditioner working with different environment friendly refrigerants
Authors: Faraj El-Sagier , Mohammed Ali Elhaj Umbarek
Published: October 2022

In this paper, the performance of various alternative refrigerants were compared to find the replacement for R22, the widely used hydrochlorofluorocarbon (HCFC) refrigerant in home air conditioning systems in most developing countries. This study include the environment friendly hydrofluorocarbon (HFC) refrigerants such as R-134a, R-410A, R-407C and R- 404A. A steady state thermodynamic modelling and simulation of a home air conditioner as an actual vapor-compression system was developed. The model predicted the performance of the system with the mentioned alternative refrigerants in terms of energy and exergy. Based on design conditions, operating parameters, such as coefficient of performance (COP), energy efficiency rating (EER), exergy efficiency (η11) and exergy destruction ratio (EDR) were evaluated. The results obtained showed that R-134a, R-410A, R407C, and R-404A are better substitute to replace R22, as they are more environment friendly air conditioning cooling applications.

In this work we intend to extend the comparative study of the mosaics of Conuentus Bracaraugustanus published in the Corpus to the mosaics from Gallaecia and from other regions of Hispania, particularly from the region between the Ebro and Douro rivers, considering different mosaic workshops operating in these areas.We also register punctual relationships between some compositional schemes, themes and motifs that occur in the mosaics of the Conuentus Bracaraugustanus and some of the north African production.We will complement our study with information that resulted from the continuation of our research and that was provided to us after the publication of the Corpus, in 2019.
The Mosaics from the Roman Villa of Pisões (Beja, Portugal). The Decorative Programme and Its Significance in the Spatial Organization of the Villa
Authors: DURAN KREMER Maria De Jesus , SERRA Miguel
Published: October 2022

Located in the Conventus Pacensis, about 7 km southwest of the Roman Pax Julia (today: Beja), this imposing Roman villa is a reference point in the study of the Roman settlements in the south of present-day Portugal. Within this group of constructions in Pisões only the pars urbana has in large part been uncovered: the existence of the wall of a dam, an aqueduct and some peripheral constructions has already been ascertained over the years.It is here that one of the most relevant sets of mosaics with figurative, vegetal and geometric motifs for the study of Roman mosaics can be found and allow the identification of possible mosaic workshops in the current territory of Portugal. Apart from a very concise description by Fernando Nunes Ribeiro in 1972, these mosaics have not yet been studied in depth.In the scope of this work the mosaics of this villa uncovered till today - most of them unpublished – are inventoried using a methodological approach of registration, study and publication, highlighting the interrelation of the pavement and the spatial planning.
Piazza Armerina. Les soi-disant personnifications de Mauretania et India aux extrémités du portique de la Grande Chasse
Authors: STEGER Brigitte
Published: October 2022

Que signifient les décors des absides du portique de la Grande Chasse ? Les personnifications au centre des deux mosaïques font-elles allusion à des entités géographiques comme cela a été proposé jusqu’à présent ? Et, dans ce cas, lesquelles ? L’analyse iconographique de chaque pavement est suivie d’un bref récapitulatif et d’une discussion des hypothèses proposées à ce jour. En nous appuyant sur un ensemble de parallèles iconographiques et textuels, nous nous efforçons de mieux cerner la signification de ces images. Nous proposons quelques pistes sur la façon dont ces mosaïques s’insèrent dans le programme décoratif du portique de la Grande Chasse auquel elles appartiennent.
