GLOBALIZAÇÃO, PROCESSOS DE CIVILIZAÇÃO, LíNGUAS E CULTURAS
Authors: Mignolo Walter D. 
Published: August 2022

Visto por Norbert Elias como um resultado da expansão colonizadora ocidental datada dos primórdios do século XVI e que se estende até os dias atuais,. o fenômeno da globalização tem provocado. ao longo de sua existência. mudanças e reorganizações das línguas e dos costumes dos povos envolvidos nos processos de colonização em todos os continentes. Segundo o antropólogo brasileiro Darcy Ribeiro, o processo de civilização não pode ser visto meramente como fenômeno limitado à expansão ocidental, como queria Elias,. mas sim concebido em termos de toda a humanidade. A discussão entre o processo de civilização de Elias e de Darcy Ribeiro é travada neste texto elaborado a partir de uma conferência sobre os processos de civilização por que passou a humanidade a partir do início do ano de J 500, quando das missões de colonização lideradas pelas então potências européias, levando sua força e impondo a subordinação aos povos colonizados, o que resultou num fenômeno único observado nos quatro cantos do mundo. Globalization, Civilization Processes, Languages and Cultures Seen by Norbert Elias as a result of the colonial expansion of the West, originating at the beginning of the 16th century and extending until our present days, the phenomenon of globalization has provoked throughout its existence changes and reorganizations in the language and habits of the peoples involved in the process of colonization on every continent. According to the Brazilian anthropologist Darcy Ribeiro, the civilization process cannot be seen merely as a phenomenon limited to the expansion of the West, as Elias suggested, but should be conceived in terms of the whole of humanity. The debate between the civilization processes of Elias and Darcy Ribeiro is examined in this text, which elaborates on a conference about the civilization processes through which humanity passed starting in the beginning of the year 1500, when the colonization missions lead by the European powers imposed through force the subordination of the colonized peoples, which lead to a unique phenomenon observed in the four corners of the world.

Published: August 2022

AbstractNaturally inspired proteins are investigated for the development of bioglues that combine adhesion performance and biocompatibility for biomedical applications. However, engineering such adhesives by rational design of the proteins at the molecular level is rarely reported. Herein, it is shown that a new generation of protein‐based glues is generated by supramolecular assembly through de novo designed structural proteins in which arginine triggers robust liquid–liquid phase separation. The encoded arginine moieties significantly strengthen multiple molecular interactions in the complex, leading to ultrastrong adhesion on various surfaces, outperforming many chemically reacted and biomimetic glues. Such adhesive materials enable quick visceral hemostasis in 10 s and outstanding tissue regeneration due to their robust adhesion, good biocompatibility, and superior antibacterial capacity. Remarkably, their minimum inhibitory concentrations are orders of magnitude lower than clinical antibiotics. These advances offer insights into molecular engineering of de novo designed protein glues and outline a general strategy to fabricate mechanically strong protein‐based materials for surgical applications.

Expanding the Diversity of Pyridines Through Annulation of Keto and Diketo Compounds
Authors: Kotha Sambasivarao , Meher Punam 
Published: August 2022

AbstractAn efficient gold [Au]‐catalyzed one‐pot synthesis has been developed for the construction of biologically interesting mono‐ and bipyridines by utilizing the commercially available cyclic ketones and propargylamine in a sealed tube. The formation of bipyridine derivative 21 a indicates that annulation followed by retro‐Diels–Alder reaction is occurring with norbornene system. However, keto‐derivatives containing bicyclo[2.2.2]octene system 25 indicate that retro‐Diels–Alder reaction is not facile. Compounds 32 a and 33 a were subjected to ring opening cross‐ metathesis to generate diversity and further functionalization of pyridine derivatives.

Published: August 2022

AbstractCRISPR/Cas system is to be a powerful tool to construct the nucleic acid diagnostic platform. Specific recognition and cleavage of CRISPR/Cas systems enable selective recognition of analytes and physicochemical signal translation of biorecognition events. Given the diversity of Cas effectors, we outline various types of Cas effectors and their associated single‐guide RNA (sgRNA), protospacer adjacent motif (PAM) sequence, or protospacer flanking sequence (PFS), as well as the characteristics of the CRISPR/Cas complex in nucleic acid detection. In light of this, we discuss the coupling of CRISPR/Cas systems to various biosensing strategies (e.g., amplification strategy, electronic methods, or optical methods) and point‐of‐care testing (POCT) (e.g., paper‐based lateral flow assays, field‐effect transistor, microfluidics devices, and solid‐state nanopore sensors) that could enable the specificity and sensitivity of the diagnostic platform for biosensing applications. Additionally, we also discuss the new frontiers and the challenges to be addressed in this field.

Published: August 2022

AbstractIn this article, we demonstrate a novel design of liquid crystal (LC) displays via predesigned radially constructed polydopamine (PDA) particles. The synthesized PDA particles were modified with dimethyloctadecyl‐3‐(trimethoxysilyl)propyl ammonium chloride (DMOAP) showing radial constructions. Both PDA particles and surface‐modified PDA particles were used to disturb the order of the LC arrangement, showing an opaque appearance. Based on the results, the radially constructed PDA particles efficiently enhanced the performance of cholesteric liquid crystal (CLC) devices. Adding 0.1 wt% DMOAP‐modified PDA particles into the CLC device shows a higher contrast of 82.2%, a lower threshold voltage of 2.4 V and a fast response time of 7.7 ms. Without adding polymer beads, no any display contrast was observed. The results suggest that the synthesized surface‐modified PDA particles disturb the alignment of LCs dispersed in LC cells, leading to a great improvement in the contrast of the CLC devices. In addition, a prepared traditional polymer stabilized CLC (PSCLC) cell shows only 2.8% contrast. The best performance, with a high contrast of 93.8%, a low threshold voltage of 10.4 V and a fast response time of 10.2 ms, was achieved by adding 0.1 wt% modified PDA particles into the CLC device.

AbstractVanadium pentoxide polymorphs are attracting much interest due to their remarkable electrochemical performance as positive electrodes for rechargeable metal‐ion batteries. High‐pressure β‐V2O5 is an interesting positive electrode material for Na‐ion batteries able to intercalate 1 Na+/formula unit delivering a capacity of 147 mAh g−1. The sodium intercalation of 0.4 Na+ has been described in the literature as a two‐phase domain involving an important structural rearrangement yielding NaxV2O5, but details about the structural changes upon sodium intercalation and structure of intercalated Na0.4V2O5 have not been elucidated so far. In this work, we performed operando synchrotron X‐ray diffraction measurements on sodium batteries on discharge. A full crystal structure determination for such phase, which we have called κ‐Na0.4V2O5, was carried out for the first time directly from operando measurements in monoclinic space group C2/m. Structural analysis was completed with bond valence sum calculations revealing the sites of intercalated sodium in κ‐NaxV2O5 and the structure was further optimized by means of density functional theory calculations. Operando X‐ray absorption spectroscopy and ex situ X‐ray photoelectron spectroscopy allowed to unveil the redox changes upon the phase transformation from β‐V2O5 into κ‐NaxV2O5, providing information about the reduction of vanadium from V5+ to V4+. The phase transformation also produced enhanced charge transfer and sodium diffusion processes, as deduced from both impedance and kinetic study.

Published: August 2022

AbstractIn January 2022, during scientific cruise 87 on the RV Academic Mstislav Keldysh in the Atlantic sector of the Southern Ocean, three hydrobiophysical cross‐sections were performed in the Bransfield Strait. Bioluminescent signals were measured in a layer of 0–200 m at each of the 24 stations located at three sites. For the first time, a new hydrobiological system ‘Salpa MA +’ was used, which made it possible to obtain novel data in the photic layer of the studied water area. Bioluminescence studies were accompanied by simultaneous measurements of background indicators: temperature, electrical conductivity, photosynthetically active radiation, and they were compared with the data from plankton samples processing. Bioluminescent potential was registered at almost all the stations. The maximum level of bioluminescence was registered in the area of the archipelago of the South Shetland Islands, where the maximum accumulation of Salpa thompsoni, Foxton 1861 was noted. The purpose of this work is to identify the main factors and patterns affecting the intensity of the bioluminescence field in the region under study.

Published: August 2022

AbstractHepatic disorders are a serious health problem threatening human beings. Cuscutae semen (CS), a widely used Chinese medicine, is a tonic to nourish the liver and kidney. Our research aimed to assess the hepatoprotective effect of CS on CCl4‐induced liver injury rats using plasma metabolomics. Liver injury in rats was induced by 40% CCl4 in olive oil twice a week for 21 days. The CS group received 2 g/kg of CS every day for 21 days. The liver tissues were used for histological studies. The serum was used for the analysis of biochemical parameters. Plasma metabolomic analysis was performed using ultra‐performance liquid chromatography coupled with quadrupole time‐of‐flight mass spectrometry. CS could relieve hepatocyte necrosis and decrease the levels of serum biochemical parameters in comparison the with CCl4 group. Principal component analysis and orthogonal partial least squares‐discriminant analysis on plasma metabolomes showed an obvious separation among the control, model, and CS groups. Heatmap showed that CS‐administered mice had similar metabolite profiles as the control group. Seven influential pathways in plasma of the hepatoprotective effect impacted by CS were identified. This study confirmed the hepatoprotective effect of CS, and the related metabolic pathways were discussed.
Kinetic Study of the Water‐Gas Shift Reaction at Ultralow Temperature over a Ru‐Based Supported Ionic Liquid Phase Catalyst
Authors: Fischer Ferdinand , Jess Andreas 
Published: August 2022

AbstractThe water‐gas shift reaction is subject to thermodynamic limitation, i.e., CO conversion increases with decreasing temperature. Thus, it is preferential to keep temperatures as low as possible at reasonable kinetic rates. In this work, the performance of a ruthenium‐based supported ionic liquid phase catalyst is shown for the water‐gas shift reaction at ultralow temperature. Furthermore, a model for the intrinsic kinetics of the water‐gas shift reaction using this supported ionic liquid phase catalyst is presented. For this purpose, a formal kinetic power law and a mechanistic general catalytic cycle kinetic approach were applied. Supported ionic liquid phase catalysts with filling levels up to 30 % were prepared. For filling levels < 13 %, internal mass transport limitations do not occur and intrinsic kinetics prevail.
Niobium and tantalum recovery from the primary source and from tin slag, an industrial challenge: A review
Authors: de Oliveira Juliana Mendes , Anes Iara Alves , Coleti Jorge Luís , Espinosa Denise Crocce Romano , de Carvalho Marcelo Siqueira , Tenório Jorge Alberto Soares 
Published: August 2022

AbstractNiobium (Nb) and Tantalum (Ta) are used to increase materials' mechanical resistance and produce lighter alloys. Worldwide Nb production reached 78 000 t in 2020. The reduced ore offer justifies the recycling of these metals from tin slag, contributing to the circular economy. Nb2O5 and Ta2O5 extraction either from the primary source or the tin slag is an industrial challenge. Nb and Ta dissolution processes already implemented are fluoride leaching, sulphuric leaching, alkaline leaching, and alkaline roasting. The fluoride process raises environmental concerns about waste control. The sulphuric method can be managed to have higher Nb and Ta extraction in a less aggressive process, if some changes are implemented, such as increasing the number of extraction steps, decreasing the pulp density, or increasing the temperature; however, the efficiency of this methodology must be tested for tin slag. The alkaline method seems to be more selective to Nb and Ta by reactants and temperature control. Despite those well‐established Nb and Ta treatments, they must be adapted to recover Nb and Ta from slag. The slag has low Nb and Ta content, while high Si and Ca concentrations exist in the matrix. This paper brings the main methods used to extract the Nb and Ta from the primary resources and an overview of Nb and Ta recovery from the slag. This investigation comes as a tool to guide the development of new methods to recover Nb and Ta from low‐grade sources such as tin slag.
Neuromorphic Liquids, Colloids, and Gels: A Review
Authors: Kheirabadi Noushin Raeisi , Chiolerio Alessandro , Szaciłowski Konrad , Adamatzky Andrew 
Published: August 2022

AbstractAdvances in flexible electronic devices and robotic software require that sensors and controllers be virtually devoid of traditional electronic components, be deformable and stretch‐resistant. Liquid electronic devices that mimic biological synapses would make an ideal core component for flexible liquid circuits. This is due to their unbeatable features such as flexibility, reconfiguration, fault tolerance. To mimic synaptic functions in fluids we need to imitate dynamics and complexity similar to those that occurring in living systems. Mimicking ionic movements are considered as the simplest platform for implementation of neuromorphic in material computing systems. We overview a series of experimental laboratory prototypes where neuromorphic systems are implemented in liquids, colloids and gels.
