Study of the Passivity Limits of Austenitic Stainless Steel in H2S-Containing Brines Using Mott-Schottky and Point Defect Model Analysis
Authors: Case Raymundo 
Published: April 2021

The objective of the study is to correlate the effects of H2S and Cl− concentration on the passivity limits and the onset of localized corrosion in UNS S31603 stainless steel by evaluating the changes in the semiconducting behavior exhibited by the passive layer. The study is accomplished experimentally by using a combination of direct and alternate current electrochemical methods, to study the passive layer formed by the stainless steel, in equilibrium with a gas phase at 2.8 MPa (400 psi) containing up to 60% mol of H2S (bal. CO2) at 25°C. The results obtained using the Mott-Schottky analysis indicate that the decrease of the passive layer stability formed on the UNS S31603 stainless steel is consistent with the increase in the electron donor carrier density. This is observed as the consequence of the effect of Cl− and H2S. In this context, the Cl− content in the brine was found to exert a larger effect than the H2S activity. The correlation with the evaluation of the passive layer using the Point Defect model suggest that both the polarizability and the rate of annihilation of the cation vacancies at the metal/film interface increase with the H2S content in the environment. This behavior can explain the increased content of Cl− and sulfides as main electron donor species, also the observable increase in the passive layer susceptibility to both stable and metastable pitting.

A polineuromiopatia do paciente crítico é uma complicação comum na Unidade de Terapia Intensiva (UTI). A sepse e a disfunção de múltiplos órgãos são os principais fatores de risco para seu desenvolvimento. O objetivo do estudo foi identificar as abordagens fisioterapêuticas e comprometimento funcional de pacientes no ambiente de terapia intensiva com polineuromiopatia. O estudo é uma revisão de literatura integrativa. Pesquisa realizada nas bases de dados PubMed, Scielo, e Google Acadêmico. A busca dos artigos decorreu-se por intermédio das palavras chaves polineuropatia, cuidados intensivos e sepse, e polyneuropathies, critical care e fisioterapia identificados através do Decs. Foi construído no período de agosto a outubro de 2019. Como critérios de elegibilidade foram escolhidos os trabalhos dos últimos 10 anos de publicação, publicados em português ou inglês, trabalhos relacionados com polineuropatia e que explanassem algum enfoque fisioterapêutico com o tratamento de pacientes internados no ambiente de terapia intensiva. Artigos não condizentes com o tema proposto, com outros tipos de polineuropatia como diagnóstico, do tipo revisão de literatura, pagos e incompletos, foram exclusos. Observou-se pouco embasamento cientifico a cerca desta complicação, que desenvolve dentro UTI, e escassez de protocolos fisioterapêuticos para este paciente. Contudo, a mobilização precoce foi descrita como um dos métodos terapêuticos mais usados nesses pacientes para sua recuperação. Pacientes criticamente enfermos na UTI com tempo prolongado, são aptos a desenvolverem patologias que aumentam ainda mais seu tempo de internação, agravando mais o seu quadro e piorando o prognóstico sem uma abordagem específica, sendo a abordagem fisioterapêutica de suma importância.

Abstract. To investigate the impacts of multiscale circulations on the
planetary boundary layer (PBL), we have carried out the PBL thermodynamic structure field experiment with a Doppler wind profile lidar, a microwave
radiometer, and a ceilometer from January 2018 to December 2019 in Beijing.
We found that the direct regulatory effect of synoptic circulation worked
through transporting and accumulating pollutants in front of mountains in
the daytime, while the indirect effect of multiscale circulations worked
through coupling mechanisms in the nighttime. The horizontal coupling of
different-direction winds produced a severe pollution convergent zone. The
vertical coupling of upper environmental winds and lower regional breezes
regulated the mixing and diffusion of pollutants by generating dynamic wind
shear and advective temperature inversion. We also found that the dominating synoptic circulations led to great differences in PBL thermodynamic
structure and pollution. The cyclonic circulation resulted in a typical
multilayer PBL characterized by high vertical shear (600 m), temperature
inversion (900 m), and an inhomogeneous stratification. Meanwhile, strong
regional breezes pushed the pollution convergent zone to the south of
Beijing. The southwesterly circulation resulted in a mono-layer PBL
characterized by low vertical shear (400 m) and inversion (200 m). The
westerly circulation led to a hybrid-structure PBL, and the advective
inversion was generated by the vertical shear of zonal winds. Strong
environmental winds of southwesterly and westerly circulations pushed the
severe-pollution zone to the front of mountains. There was no distinct PBL
structure under the anticyclone circulation. The study systematically
revealed the appreciable effects of synoptic and regional circulations on
PBL structure and air quality, which enriched the prediction theory of
atmospheric pollution in the complex terrain.

Published: April 2021

Medicinal plants synthesize various secondary metabolites that can be used for therapeutic and antimicrobial purposes. In Brazil, the Unified Health System (SUS) offers several herbal medicines as an alternative in the treatment of various diseases. Considering the importance of these plants in the production of chemicals that expand therapeutic options and improve the health of SUS users, this review was carried out to quantitatively determine the antifungal activity of plants used as phytotherapeutics at RENAME. The selection of papers was performed at three distinct stages: examining and choosing titles related to antifungal action, reading the abstracts, and reading the whole selected articles. This review selected 22 studies of interest; 12 of them were conducted in Brazil and 10 were carried out in other countries. The papers chosen tested the growth inhibitory effect of plants against fungal species of agricultural and health importance, ranging from filamentous to yeast-like fungi, and Candida albicans was the most tested species. The growth of 39 fungal species were inhibited by some concentration of the extract used, with either an increase or decrease in antifungal activity depending on the extract used. The most frequently analyzed plant was the species Schinus terebinthifolius Raddi., studied in seven papers. The results found demonstrate the importance of analyzing medicinal plants and incorporating plant-based medicines in healthcare as an alternative source of treatment, highlighting the need for studies that evaluate the mechanisms action of their cytotoxicity and therapeutic effects in the human body.

Published: April 2021

Background and objective: By adopting a trauma-informed approach to care at the organisational and clinical levels, health care systems and providers can enhance the quality of care that they deliver and improve health outcomes for individuals with a trauma history. This study aimed to explore the trauma-related knowledge, attitudes awareness, practice, competence and confidence of health service staff from three small rural health services in Victoria, Australia, and examine their self-reported capacity to respond to clients with a trauma history.Methods: Staff from each site were invited to complete a paper-based survey. The survey included demographic information and questions related to knowledge and understanding of trauma, experience of trauma-informed care and confidence engaging in, and perceived importance of, trauma-informed practices. Results: The respondents were predominately nurses. Results showed that 16% of respondents had undertaken training in trauma-informed care and 44% disagreed that they had an understanding of trauma-informed practices. There were high levels of agreement for statements related to knowledge and understanding of trauma and low levels of agreement with statements related to experience of trauma-informed care. More than 70% of respondents reported that they had little knowledge of the principals of trauma-informed care, and little experiencing with practicing trauma-informed care.Discussion and conclusions: Overall, the survey results showed that staff were trauma-aware, but supported the need for more education and training in trauma-informed practices and improved organisational approaches to support trauma-informed approaches. It is important for organisations to shift from being trauma aware to being trauma-informed, by building foundational awareness of these practices and reinforcement through continuing education.

Published: April 2021

Background & Objectives
The massive outbreak of Novel Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) has turned out to be a serious global health issue worldwide. Currently, no drugs or vaccines are available for the treatment of COVID-19. The current computational study was attempted to identify a novel therapeutic inhibitor against novel SARS-CoV-2 using in silico drug discovery pipeline.

Methods
In the present study, the human angiotensin-converting enzyme 2 (ACE2) receptor was the target for the designing of drugs against the deadly virus. The 3D structure of the receptor was modeled & validated using a Swiss-model, Procheck & Errat server. A molecular docking study was performed between a group of natural & synthetic compounds having proven anti-viral activity with ACE2 receptor using Autodock tool 1.5.6. The molecular dynamics simulation study was performed using Desmond v 12 to evaluate the stability and interaction of the ACE2 receptor with a ligand.

Results
Based on the lowest binding energy, confirmation, and H-bond interaction, cinnamic acid (−5.20 kcal/mol), thymoquinone (−4.71 kcal/mol), and andrographolide (Kalmegh) (−4.00 kcal/mol) were screened out showing strong binding affinity to the active site of ACE2 receptor. MD simulations suggest that cinnamic acid, thymoquinone, and andrographolide (Kalmegh) could efficiently activate the biological pathway without changing the conformation in the binding site of the ACE2 receptor. The bioactivity and drug-likeness properties of compounds show their better pharmacological property and safer to use.

Interpretation & Conclusions
The study concludes the high potential of cinnamic acid, thymoquinone, and andrographolide against the SARS-CoV-2 ACE2 receptor protein. Thus, the molecular docking and MD simulation study will aid in understanding the molecular interaction between ligand and receptor binding site, thereby leading to novel therapeutic intervention.

Published: April 2021

This study examined team communication and mutual support as drivers of work performance among team members in the organization. The cross-sectional research design was used and with standardized instruments, data were collected from 133 participants from manufacturing organizations consisting of 63.9% males and 36.1% females whose age ranged from 21-54 years with a mean age of 31.71(SD, 8.7). Work performance was grouped into task performance, contextual performance and counterproductive work behaviour. The hypotheses were tested with the simple regression analysis. Data analysis revealed that team communication positively predicted task performance (β = .56, p < 0.01) and contextual performance (β = .55, p < 0.01) while it negatively predicted counterproductive work behaviour (β = -.21, p < 0.05). Also, mutual support positively predicted task performance (β = .80, p < 0.01) and contextual performance (β = .80, p < 0.01) while it negatively predicted counterproductive work behaviour (β = -.17, p < 0.05). The study recommends that management should encourage employees to work together and also educate them on these key behaviours (communication and mutual support) to help enhance employee performance in the organization.

AbstractA variety of unconventional materials, including biological nanostructures, organic and hybrid semiconductors, as well as monolayer, and other low‐dimensional systems, are actively explored. They are usually incompatible with standard lithographic techniques that use harsh organic solvents and other detrimental processing. Here, a new class of green and gentle lithographic resists, compatible with delicate materials and capable of both top‐down and bottom‐up fabrication routines is developed. To demonstrate the excellence of this approach, devices with sub‐micron features are fabricated on organic semiconductor crystals and individual animal's brain microtubules. Such structures are created for the first time, thanks to the genuinely water‐based lithography, which opens an avenue for the thorough research of unconventional delicate materials at the nanoscale.

AbstractSurface modification of biomaterials is a promising approach to control biofunctionality while retaining the bulk biomaterial properties. Perlecan is the major proteoglycan in the vascular basement membrane that supports low levels of platelet adhesion but not activation. Thus, perlecan is a promising bioactive for blood‐contacting applications. This study furthers the mechanistic understanding of platelet interactions with perlecan by establishing that platelets utilize domains III and V of the core protein for adhesion. Polyvinyl chloride (PVC) is functionalized with recombinant human perlecan domain V (rDV) to explore the effect of the tethering method on proteoglycan orientation and bioactivity. Tethering of rDV to PVC is achieved via either physisorption or covalent attachment via plasma immersion ion implantation (PIII) treatment. Both methods of rDV tethering reduce platelet adhesion and activation compared to the pristine PVC, however, the mechanisms are unique for each tethering method. Physisorption of rDV on PVC orientates the molecule to hinder access to the integrin‐binding region, which inhibits platelet adhesion. In contrast, PIII treatment orientates rDV to allow access to the integrin‐binding region, which is rendered antiadhesive to platelets via the glycosaminoglycan (GAG) chain. These effects demonstrate the potential of rDV biofunctionalization to modulate platelet interactions for blood contacting applications.

AbstractThe dynamic spreading phenomenon of liquids is vital for both understanding wetting mechanisms and visual reaction time‐related applications. However, how to control and accelerate the spreading process is still an enormous challenge. Here, a unique microchannel and nanofiber array morphology enhanced rapid superspreading (RSS) effect on animals’ corneas with a superspreading time (ST) of 830 ms is found, and the respective roles of the nanofiber array and the microchannel in the RSS effect are explicitly demonstrated. Specifically, the superspreading is induced by in‐/out‐of‐plane nanocapillary forces among the nanofiber array; the microchannel is responsible for tremendously speeding up the superspreading process. Inspired by the RSS strategy, not only is an RSS surface fabricated with an ST of only 450 ms, which is, respectively, more than 26 and 1.8 times faster than conventional superamphiphilic surfaces and animal's corneas and can be applied as RSS surfaces on video monitors to record clear videos, but also it is demonstrated that the RSS effect has tremendous potential as advanced ophthalmic material surfaces to enhance its biocompatibility for clear vision.

AbstractThe localized functionalization of pores and channels of micrometric and sub‐micrometric sizes is a bottleneck in surface chemistry. A method for the regioselective chemical functionalization of planar pores is presented, that are, restrictions in microfluidic channels, here made of SiO2‐coated silicon. This strategy, based on bipolar electrochemistry, exploits the combined presence of the constriction and a localized deoxidation pattern within the pore that affects the electrical field distribution inside the microfluidic channel. It is not only shown that it is capable of regioselectively functionalizing a planar pore at relatively small potential difference applied across it, but also the possibility of positioning the functionalization area inside or at the edges of the pore depending on the design of the deoxidation pattern is proved. These results are in perfect correlation with the numerical simulations of electric field distribution in micropores carried out using the software Comsol Multiphysics. This functionalization technique is therefore very promising, particularly in the field of biosensors. A specific DNA hybridization test has been successfully carried out, which represents a first step toward bioanalytical and health applications.

AbstractThe field of post‐synthesis modification has aroused widespread concern from diverse perspectives, including chemistry, biology, and material science. Post‐synthesis modification can introduce rich functionality into metal–organic frameworks (MOFs) without destroying the main structure of MOFs. Based on this research status, a series of lanthanide metal–organic frameworks ([Ln2(NH2‐BDC)2.5(CH3COO)(DMA)(H2O)]•DMA, Ln = Pr, Nd, Sm, Eu, Gd and Tb, NH2‐BDC = 2‐aminoterephthalic acid, DMA = N,N‐Dimethylacetamide) with 3D network structures, are synthesized by hydrothermal synthesis. Due to the presence of uncoordinated amino groups in the ligands, a series of post‐synthesis modified compounds are successfully synthesized through aldimine condensation reaction. Based on the good fluorescence properties and stable structure of coordination polymers and post‐synthesis modified compounds in water or organic solvents, they are able to be used as potential fluorescence sensor for the detection of Th4+, UO22+, and Cr2O72−, and the calculation result shows that the post‐synthesis modified compounds are more sensitive to the detection of analytes (Th4+, UO22+ and Cr2O72−) than coordination polymers. In addition, the MOF membrane prepared by self‐assembly of [Eu2(NH2‐BDC)2.5(CH3COO)(DMA)(H2O)]•DMA and ternary soap‐free copolymer (VAc‐AA‐BA) emulsion can be used first for detecting aldehyde vapors.
