Embedding Multi-Wall Carbon Nanotubes as Conductive Nanofiller onto Bi2Te3 Thermoelectric Matrix
Authors: Silva Almeida Miguel Ângelo , Magalhães João M. , Maia Maria M. , Pires Ana L. , Pereira André M.
Published: June 2022

Thermoelectric Generators (TEGs) are devices that have the ability to directly convert heat into electrical power, or vice-versa, and are being envisaged as one off-the-grid power source. Furthermore, carbon-based materials have been used as a conducting filler to improve several properties in thermoelectric materials. The present work studied the influence on the thermoelectric performance of Bi2Te3 bulk materials by incorporating different concentrations of Multi-Walled Carbon Nanotubes (MWCNT). In order to control and understand the influence of MWCNT dispersion in the nanocomposite, two different production methods (manual grinding and ultrasonication) were carried out and compared. It was verified that a larger dispersion leads to a better outcome for thermoelectric performance. The achieved Seebeck coefficient was up to -162 µV K-1 with a Power Factor of 0.50 µW K-2m-1, for the nanocomposite produced with 11.8 %V of MWCNT. This result demonstrates the ability to increase the thermoelectric performance of Bi2Te3 throughout the addition of MWCNT.
Nematic Liquid Crystals as a Tabletop Platform for Studying Turbulence
Authors: Silva Ferreira Tiago David , A. Silva Nuno , Guerreiro Ariel
Published: June 2022

Light propagating in nonlinear optical materials opens the possibility to emulate quantum fluids of light with accessible tabletop experiments by taking advantage of the hydrodynamical interpretation. In this context, various optical materials have been studied in recent years, with nematic liquid crystals appearing as one of the most promising ones due to their controllable properties. Indeed, the application of an external electric field can tune their nonlocal response, and this mechanism may be useful for producing fluids of light and developing optical analogues. In this work, we extend the applicability of nematic liquid crystal to support optical analogues and study the possibility of emulating turbulent phenomena by using two fluids of light. These fluids interact with each other through the nonlinearity of the medium and generate instabilities that will lead to turbulent regimes. We also explore the possibility of exciting turbulent regimes through the decay of dark soliton stripes. The preliminary results are presented.
Not all cardiac tumors are myxomas and not all benign tumors are benign: two case reports
Authors: Khoury Antoine El , Nasr Samer , Darwich Lynn , Othman Leen , Mahfouz Elissa , Farhat Kassem , Jomaa Abbas , Tedy Georges
Published: June 2022

Background:

Primary cardiac tumors originating in the heart are much less frequent than metastasis from other organs. The majority of cardiac tumors are of benign nature and only 25% are estimated to be malignant. Common symptoms of cardiac tumors include systemic embolization, congestive heart failure, and arrhythmias.

Case report:

We present two cases of cardiac tumors initially causing heart failure symptoms and valvular disease in relatively young patients. These tumors were initially diagnosed as myxomas, but post-op histological studies revealed the presence of angiosarcoma and hamartoma. It is important to differentiate and have a clear diagnosis because some malignant and invading tumors may require the use of adjuvant chemotherapy agents.

Conclusion:

It should not be taken for granted that cardiac tumors are of benign nature even if initial evaluation is consistent with myxomas. Early resection and pathological study of primary cardiac tumors are important in identifying the tumor type and targeting management.
Colombia 1971: Trabajadores del Arte Revolucionario y movimiento estudiantil
Authors: Barón María Sol , Ordóñez Camilo
Published: June 2022

The emergence of the Cultural Front (FC) of the Movimiento Obrero Independiente Revolucionario (MOIR) was a space for artistic practices with a partisan vocation focused on propaganda, social unrest and political militancy. Crossing history, art history and visual studies, we reconstruct the forms of political imagination that allowed them to project artistic and cultural practices with a vocation to intervene and transform the reality that MOIR embraced, in the context of the new left in Colombia and the consolidation of a student movement in 1971. We consider that this niche, contextualized and interdisciplinary, fostered the performativity of images in MOIR’s visual culture that today function as a place of memory to reconsider that moment and its survival.
Monuments of Dissidence: 3D Models of the Social Unrest in Chile by the Artist Collective Antes del Olvido
Authors: Pfaller Schmid Matthias Johannes
Published: June 2022

The artist collective Antes del Olvido formed in 2019 during the crisis in Chile to document significant locations of the protest as 3D models. Their goal is “to collectively produce an archive of the uprising” as “a political tool, an artifact for collective memory.” Drawing on the concept of artivism, I discuss various aspects of these images: first, their place among cellphone snapshots, graffiti, the urban fabric, and the circulation of symbols across these media. Second, I investigate the importance of location and movement in the protests and its preservation in the 3D models. Finally, I reflect on their role as citizen-generated monuments in providing agency to the artists and the public in shaping historical memory.
Factors Affecting the Agricultural Restructuration: A Case of Cham Community in Chau Phu District, An Giang Province, Vietnam
Authors: Thanh Pham Van Huynh , Hong Lam Cam Thi , Nguyen Nghia Ngoc
Published: June 2022

The national policy of agricultural restructuring plays a vital role in adapting to climate change's effects and economic development in the Mekong Delta of Vietnam. Unproductive areas have been converted into other crops with higher efficiency. Drawn by the sustainable livelihoods approach, this article explores the current situation and factors challenging the Cham community in implementing the agricultural restructuring. The mixed method included in-depth interviews, focus group discussions, and a questionnaire survey. The results showed that the Xuong Com Vang longan (Dimocarpus longan) variety has occurred in Khanh Hoa commune for a long time as an indigenous fruit tree of this area. In terms of the farming system, the polyculture system combining fruit trees and upland crops brought more income sources than the monoculture system. The asset abilities of the Cham farmers are various from one to the others. Soil and weather conditions are appropriate for planting. But farm size is small, which is one of the difficulties of developing fruit areas. Human and social assets were good since farmers had enough knowledge to manage the gardens, and a close connection existed among the Cham community. It was not a case of the financial status since a lot of money needs to be invested in the starting year. Therefore, the private loan still exists as one of the farmer's choices. For better future development, land management and financial resource should be considered for better agricultural restructuring aims. To increase farmers' incomes, create production chains helping enterprises and farmers work more efficiently for the better life of Cham gardeners in An Giang province in Vietnam.
The regulation of salt and drought stress responses by SDR and its interacting proteins in arabidopsis
Authors: Obara Justus Anyieni , Abincha Wilfred Magangi
Published: June 2022

The ubiquitin/26S proteasome pathway is key to protein degradation in plants. Its specificity often orchestrated by ubiquitin-protein ligases (or E3s), which facilitate the translocation of ubiquitin to appropriate targets. F-box protein is one of the subunit of E3 ligases SCF (Skp1-Cullin/CDC53-F-box). It has been reported that F-box protein is not only related to plant growth but also abiotic stress. In this study, the protein was found localised in the nucleus and its function was identified. It demonstrated that on salt treatment SDR is involved in salt and drought stress response in Arabidopsis. However, the function of most F-box proteins is unknown. In this paper, the full length of the F-box protein SDR gene was cloned by traditional reverse molecular biology methods, and related transgenic materials were constructed. Bioinformatics analysis of the cis-element of the promoter of F-box protein was used to screen F-box proteins that may be stressed by plants. We found a large number of abiotic stress response elements such as drought stress response elements, salt stress response elements, and heat shock response elements in the promoter sequence upstream of the SDR (At5g15710) gene. The results show that SDR can be induced by ABA, heat shock, and salt, but expression is suppressed under drought treatment.
Fragile X syndrome in Ricaurte, Colombia
Authors: Saldarriaga Gil Wilmar
Published: June 2022

This is an extraordinary book that has grown out of a wonderful collaboration between scientists, clinicians, and advocates at two institutions committed to improving the lives of families affected by neurodevelopmental disorders: the UC Davis MIND Institute in the United States and the Universidad Del Valle in Colombia. The collaboration has been led by Drs. Randi J. Hagerman and Wilmar Saldarriaga Gil, but has involved many dozens of people over a period of three years. This book presents information about the cutting-edge scientific findings and technologies used to study fragile X syndrome (FXS), the leading cause of inherited intellectual disability and the most common single-gene cause of autism spectrum disorder. What makes the book unique, however, is the application of this scientific knowledge to the team’s work in Ricaurte, Colombia. Ricaurte is a small rural town in the Valle del Cauca region, Southwest of Bogota.

The convent of San José in La Orotava opened its doors in January 1601, but the project to found it was conceived much earlier. Over the centuries it grew architecturally until it occupied the entirety of the most coveted block in the urban center of the town. It survived until 1869, when it was closed and demolished. This article covers the moments prior to the foundation and the subsequent development of the building until its disappearance, from the point of view of its architecture and incorporating historical data and information to complete the outline of its history.
La circunnavegación de África por parte de los hermanos Vivaldi en 1291: precursores de Vasco da Gama
Authors: Quartapelle Alberto
Published: June 2022

In 1291, the brothers Vadino and Ugolino Vivaldi set off from Genoa in two galleys with the aim of reaching ad parte Indiae. A document lost for 700 years, Galvano Fiamma’s Ystoria Ethyopie, offers new elements that allow us to conclude the Vivaldi managed to circumnavigate Africa on their expedition and, therefore, they can be considered the forerunners of Vasco da Gama. Documents are presented in the appendix that show that the Allegrancia galley did not participate in such undertaking, and, for that reason, it could not give its name to the northernmost of the Canary Islands, the Island of Alegranza.

Anak hambatan pendengaran adalah anak yang mengalami kehilangan kemampuan dengar yang meliputi seluruh gradasi, baik ringan, sedang maupun berat, dan walaupun diberikan alat bantu mendengar tetap memerlukan layanan pendidikan  khusus. Dasar dari layanan pendidikan bagi anak dengan hambatan pendengaran adalah asesmen fungsi pendengaran dan asesmen pendukung lainnya. Dampak dari hambatan pendengaran adalah terjadinya kemiskinan bahasa dan bicara, yang berdampak pula pada aspek perkembangan lainnya. Hal ini disebabkan karena anak tidak mendengar bahasa sejak usia dini. Untuk mengatasi terhambatnya perkembangan bahasa tersebut, maka sangat diperlukan adanya intervensi edukatif berupa program bimbingan orangtua agar orangtua dapat memenuhi kebutuhan khusus anak akibat dari hambatan pendengarannya, pengembangan aspek sosial dan emosi, serta pemberian latihan kemampuan mendengar melalui program Pengembangan Komunikasi Persepsi Bunyi dan Irama. Proses pemerolehan dan penguasaan bahasa menggunakan strategi dan prosedur secara alami seperti yang terjadi pada anak mendengar pada umumnya dalam lingkungan bahasa.

Sunflower is main oil crop in the Russian Federation. One of the general factors decreasing its yields is broomrape. The most effective method to protect the crops is breeding of resistant forms of sunflower. The purpose of this work is to genotype and to analyze basing on isoenzymes and SSR-loci the molecular-genetic diversity of the collection of lines – donors of resistance to broomrape race G bred at V.S. Pustovoit All-Russian Research Institute of Oil Crops. An object of the research was 14 lines of the different origin – donors of the resistance to this broomrape race: 2RGB, 2RGNV, 2RGA, 2RGN, 2RGS, RGL1, RGL2, RGP1, RGP2, RGB, RGN, RGM, RGA, and RG. DNA was isolated by STAB-method from the cotyledons of seven-day etiolated sunflower seedlings. Genotyping was conducted using 15 microsatellite loci and four isoenzymes systems. The indicators of a discrim-inating potential of used 15 microsatellite loci were calculated by the standard formulas. Cluster analysis was done by Ward-method in a program Statisticа 6.0. There were identified 14 lines-donors. The collection was analyzed by the isoenzymes and microsatellite loci; the unicity is 64% and 100%, respectively. The discriminating potential of a system of DNA-markers is average. Due to cluster analysis, all lines were divided into two groups. The maximal distance between the lines was 7.4. In spite of the studied lines have a common trait – resistance to the broomrape race G, their molecular traits distinguished. According to the different genetic background, these lines can be used as a source of the additional diversity when in-volving into the breeding of sunflower resistant to broomrape race G.
From minimalism to the archaic(on the problem of interpretation of ethno-specific concepts in the works of the composer Rahilia Hasanova)
Authors: Ахундова-Дадашзаде Зумруд Араз кызы
Published: June 2022

1970-е годы ознаменованы появлением новой генерации азербайджанских композиторов - воспитанников Кара Караева. Унаследовав от своего учителя такие свойства, как глубинный подход к традициям национальной музыкальной культуры, устремлённость к «новым берегам», семидесятники смогли привнести в азербайджанскую музыку свежую струю. Одной из наиболее самобытных представительниц этого поколения является Рахиля Гасанова. Некоторые особенности стиля Гасановой - редукция до минимума привлекаемого материала, репетитивность, - вызывают параллели с «классическими» образцами минимализма. Однако для автора минимализм - всего лишь техника, служащая выявлению сущностных признаков этнокультуры, таких явлений, как ковёр, древние театрализованные представления, суфийские ритуалы. Все эти этноспецифичеcкие концепты, впервые воплощённые в академической музыке Гасановой, наделяются новыми смыслами благодаря изобретательному и продуманному применению завоеваний авангарда. Сочетание медитативности, статики и действенности, целенаправленное прорастание исходной ритмоинтонационной формулы, крещендирующая форма с ярко очерченной кульминационной зоной свидетельствуют о симфоничности мышления композитора. Органичный сплав национальных когнитивных моделей с новыми методами композиции приводит к художественным открытиям, обогащающим картину современного музыкального мира

The 70s were marked by the emergence of a new generation of Azerbaijani composers, which were the students of Kara Karayev (Gara Garayev). Having inherited from their teacher such features as an in-depth approach to the traditions of the national musical culture, and an aspiration to “new coasts”, the ’70s were able to bring a freshness to Azerbaijani music. One of the most original representatives of this generation of composers is Rahilia Hasanova. Some components of Hasanova’s style, for example, the reduction to a minimum of the material involved, repetitiveness, additivity, push to draw parallels with the classical examples of minimalism. For Hasanova, minimalism is just a technique that serves to reveal the essential features of the ethnic local culture, such phenomena as a carpet, ancient theatrical performances, and Sufi rituals. All these ethno-specific concepts, first introduced by Hasanova to the Azerbaijani composed music, are endowed with new meanings thanks to the inventive and thoughtful application of avant-garde achievements. The combination of meditativeness, statics, and dynamics, purposeful germination of the original rhythm-intonation formula, crescendoing form with a clearly defined climax zone testify to the symphonicity of the composer's thinking. The organic fusion of national cognitive models with the new methods of composition leads to artistic revelations that enrich the picture of the modern musical world

Hybrid dense carbon allotropes from crystal chemistry and first principles: 'glitter' C6, 'isoglitter' C8 and 'metaglitter' C8
Authors: Matar Samir F. , Solozhenko Vladimir L.
Published: June 2022

Oppositely to diamond which is built of corner sharing C4 tetrahedra with C(sp3), the presence of mixed carbon hybridization (sp2 and sp3) in three carbon allotropes derived from so-called 'glitter' has been shown through DFT-based quantum calculations to produce stable systems sharing some properties of diamond with regard to hardness, thermodynamics and electronic properties. The three carbon allotropes, 'glitter' (C6), 'isoglitter' (C8), and 'metaglitter' (C8) were found to be dynamically stable and characterized by large bulk and shear moduli and very high hardness. A metallic behavior arising from trigonal C(sp2) forming pairs, is observed for 'glitter' and 'isoglitter', while 'metaglitter' is closer to diamond due to the semi-conducting behavior. The novel carbon allotropes are proposed as an opportunity for materials science with potential for applications as superabrasives and in electronic devices.
Suspended phospholipid bilayers: a new and versatile biological membrane model
Authors: Ayscough Sophie , Titmuss Simon , Clifton Luke , Skoda Maximilian
Published: June 2022

We present a reliable method of forming a fluid phase lipid bilayer suspended underneath a surfactant monolayer at the air-water interface, a novel bacterial membrane mimic. Bilayer formation proceeds by vesicle adsorption and subsequent rupture beneath a monolayer of a cationic surfactant adsorbed at the air-water interface of a laminar ow trough. The laminar flow facilitates buffer exchange beneath the surfactant monolayer, allowing for sequential deposition of vesicles, osmotic rupture and sub-phase contrast variation for neutron reflectometry. As the lipid bilayer formed by this process does not interact with a solid substrate, the suspended bilayer platform is well-suited to studying lipid bilayers including inserted membrane proteins.

Published: June 2022

Nature has bestowed us with abundant bioactive/drug molecules for various uses in our everyday life. One such group of plant specialized molecules is limonoids, which are structurally characterized as 4,4,8-trimethyl-17-furanyl steroidal skeleton. Limonoids are well known for their various biological activities such as potent anti-feedent, anti-cancer, anti-inflammatory, insecticidal, anti-diabetic, anti-viral, anti-microbial etc. These tetranortriterpenes are highly oxygenated and structurally diversified molecules majorly found in Meliaceae and Rutaceae and less frequently in the Cneoraceae families in the plant kingdom. Many of these plants have been used in traditional medicine from ages. One of the well-known limonoid, azadirachtin A is highly valued and widely popular for its outstanding insecticidal properties. Till date, nearly 2500 limonoids with over 35 unique carbon frameworks have been observed. In recent times, these molecules have dig a great interest among researchers due to their myriad biological properties. With the advancement of analytical techniques, the limonoid research is aced to explore more different molecules from their sources. In our review we cover all the Meliaceous limonoids isolated during July 2010 to Dec 2020. We found over 1502 new limonoids, which are reported from various Meliaceae plants after Jun 2010. We have classified them based on their skeletal structure rearrangements and functional groups into various classes such as protolimonoids, Apoprotolionoid, Azadirone, Vilasinin, Cedrelone, Havanensin, Trichilin, Nimbin, Salannin, Azadirachtin, Nimbolidin, Nimbolinin, Obacunol, Evodulone, Trijugin, Cipadesin, Andirobin, Mexicanolide, Phragmalin, Khayanolide, Preieurianin, Aphanamixoid, Nor Limonoid and N-containing derivatives. Further we have discussed their biological activities in detail.

Published: June 2022

Phase behavior of confined fluids adsorbed in na-nopores differs significantly from their bulk coun-terparts and depends on the chemical and structural properties of the confining structures. In general, phase transitions in nanoconfined fluids are reflect-ed in stepwise adsorption isotherms with a pro-nounced hysteresis. Here, we show experimental evidence and in silico interpretation of the reversi-ble stepwise adsorption isotherm which is observed when methane is adsorbed in the rigid, crystalline metal-organic framework IRMOF-1 (MOF-5). In a very narrow range of pressures, the adsorbed fluid undergoes a structural and highly cooperative re-construction and transition between low-density and high-density nanophases, as a result of the competition between the fluid-framework and flu-id-fluid interactions. This mechanism evolves with temperature: below 110 K a reversible stepwise iso-therm is observed, which is a result of the bimodal distribution of the coexisting nanophases. This temperature may be considered as a critical temper-ature of methane confined to nanopores of IRMOF-1. Above 110 K, as the entropy contribution in-creases, the isotherm shape transforms to a common continuous S-shaped form that is characteristic to a gradual densification of the adsorbed phase as the pressure increases.
Direct Processing and Storage of Cell-free Plasma using Dried Plasma Spot Cards
Authors: Baillargeon Keith R. , Morbioli Giorgio Gianini , Brooks Jessica C. , Miljanic Philip R. , Mace Charles R.
Published: June 2022

Plasma separation cards represent a viable approach for expanding testing capabilities away from clinical settings by generating cell-free plasma with minimal user intervention. These devices typically comprise a basic structure of plasma separation membrane (PSM), unconstrained porous collection pad, and utilize either (i) lateral or (ii) vertical fluidic pathways for separating plasma. Unfortunately, these configurations are highly susceptible to (i) inconsistent sampling volume due to differences in patient hematocrit or (ii) severe contamination due to leakage of red blood cells (RBCs) or release of hemoglobin (i.e., hemolysis). Herein, we combine the enhanced sampling of our previously reported patterned dried blood spot (pDBS) cards with an assembly of porous separation materials to produce a patterned dried plasma spot (pDPS) card for direct processing and storage of cell-free plasma. Linking both vertical separation and lateral distribution of plasma yields discrete plasma collection zones that are spatially protected from potential contamination due to hemolysis and an inlet zone enriched with blood cells for additional testing. We evaluate the versatility of this card by quantitation of three classes of analytes and techniques including: (i) soluble transferrin receptor by enzyme-linked immunosorbent assay (ELISA), (ii) potassium by inductively coupled plasma atomic emission spectroscopy (ICP-AES), and (iii) 18S rRNA by reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). We achieve quantitative recovery of each class of analyte with no statistically significant difference between dried and liquid reference samples. We anticipate that this sampling approach can be applied broadly to improve access to critical blood testing in resource limited settings or at the point of care.
In-situ synthesis of reagents in paper-based analytical devices using paper stacking
Authors: Chauhan Ayushi , Mittal Mohet , Toley Bhushan
Published: June 2022

This article demonstrates a technique for the in-situ synthesis of an insoluble analytical reagent in paper analytical devices, using paper stacking. Previously, our group has demonstrated that stacking a fast-wicking paper membrane on top of a slow-wicking paper membrane containing dried reagents enables the uniform rehydration of the dried reagents over large areas. This technique is utilized here to fabricate distance-based sweat chloride quantification strips, which requires the synthesis of insoluble silver chromate as an analytical reagent within paper. The in-situ generation of silver chromate for sweat chloride detection was previously accomplished by manually dipping a hydrophobically patterned paper channel into multiple precursor solutions with intermittent washing and drying. Compared to the previous technique, the stacking method obviates the need for i) patterning hydrophobic barriers in paper for creation of flow channels, and ii) multiple dipping steps that need large reagent volumes. The method is amenable to large scale manufacturing as the insoluble reagent can be synthesized uniformly over large paper areas and can then be cut into multiple sensing strips. The developed sensor has a limit of detection of ~0.3 mM and a wide linear dynamic range of 0-120mM for the detection of chloride ion, which enables the diagnosis of cystic fibrosis, characterized by sweat chloride levels greater than 60 mM. This simple technique of in-situ synthesis of insoluble analytical reagents in paper could enable expanding the range of analytical chemistries that may be performed in paper-based analytical devices.

Published: June 2022

The effect of surface roughness of the catalyst layer (CL) based on carbon-nanotube (CNTs) in contact with polymer electrolyte membrane (PEM) in polymer electrolyte membrane fuel cell (PEMFC) was studied. The surface roughness of vacuum-filtrated CL sheets were evaluated using laser microscope and the surface of CL sheet contacting the filter membrane was found to be smoother compared to the surface exposed to the air. When a smoother surface of the CL sheet was laminated with PEM to fabricate membrane-electrode-assembly (MEA), power density of the single cell was 604.6 mW cm-2 at 80 °C under 100%R.H., which was greater than the MEA having a rougher CL surface (542.4 mW cm-2).
Spin-Coupled Generalized Valence Bond Theory: An Appealing Orbital Theory of the Electronic Structure of Atoms and Molecules
Authors: Dunning Thom , Cooper David , Xu Lu , Karadakov Peter
Published: June 2022

This chapter outlines the basic elements of Spin-Coupled Generalized Valence Bond (SCGVB) theory, including the structure of the SCGVB wavefunction as well as its optimization and analysis. The SCGVB wavefunctions accounts for non-dynamical electron correlation yet still provides a compelling orbital description of the electronic structures of the ground and excited states of molecules and of the electronic mechanisms of chemical reactions. The insights provided by SCGVB theory are illustrated using a representative set of examples: the “traditional” HCN molecule, and its fragmentation into CH and N; the formation of “hypervalent” SF4 and SF6 from SF(n–1) + F; resonance/antiresonance in benzene and tropylium cation (C7H7+ ); the excited states of benzene, CH and O3/SO2 ; and the reaction of ground state methylene with H2 . The effects of dynamical electron correlation, which must be included to make quantitative predictions of molecular properties, can be taken into account by using the SCGVB wavefunction expressed in natural orbitals as the reference wavefunction in traditional multireference configuration interaction calculations.
Biocompatible and selective generation of bicyclic peptides
Authors: Ullrich Sven , George Josemon , Coram Alexandra , Morewood Richard , Nitsche Christoph
Published: June 2022

Bicyclic peptides possess superior properties for drug discovery; however, their chemical synthesis is not straightforward and often neither biocompatible nor fully orthogonal to all canonical amino acids. The selective reaction between 1,2-aminothiols and 2,6-dicyanopyridine allows direct access to complex bicyclic peptides in high yield. The process can be fully automated using standard solid-phase peptide synthesis. Bicyclization occurs in water at physiological pH within minutes and without the need for a catalyst. The use of various linkers allows tailored bicyclic peptides with qualities such as plasma stability, conformational preorganization, and high target affinity. We demonstrate this for a bicyclic inhibitor of the Zika virus protease NS2B-NS3 as well as for bicyclic versions of the α-helical antimicrobial peptide aurein 1.2.
