Sulfamic acid is an environment-friendly alternative electrolyte for industrial acid cleaning and corrosion inhibition: a mini review
Authors: Verma Chandrabhan , Quraishi Mumtaz A. 
Published: February 2022

Abstract
Sulfamic acid (H3NSO3), which is also known as amino sulfuric acid, sulfamidic acid, amidosulfonic acid, and aminosulfonic acid, is an industrially useful water-soluble colorless crystalline solid. Sulfamic acid solutions of different concentrations are widely used for the removal of scales and metal oxides deposits from the surface of metals and ceramics. Sulfamic acid solutions (5–10%) serve as alternative electrolytes for the removal of rusts and lime scales to replace relatively more irritating and volatile hydrochloric and sulfuric acid-based electrolytes. Sulfamic acid solutions can be regarded as relatively more environmentally friendly and less toxic electrolytes for the cleaning of metallic surfaces. However, similar to the popular acidic solutions, sulfamic acid based electrolytes are corrosive to metal and metallic structures. Therefore, organic compounds based corrosion inhibitors of natural and synthetic origin are widely used to prevent corrosive damage of metallic surfaces in such electrolytes. These compounds become effective by adsorbing on the metallic surface following through the Langmuir adsorption isotherm model. Using electrochemical analyses it was observed that organic corrosion inhibitors in sulfamic acid based electrolytes behave as mixed- and interface-type corrosion inhibitors and they become effective by adsorbing at the metal/electrolyte interfaces. The adsorption of most of the corrosion inhibitors mostly follows physiochemisorption mechanism.

Published: February 2022

Abstract
Metallic materials are widely utilized in the fields of industry, agriculture, transportation and daily life for their high mechanical strength, and relatively low cost. However, the microorganisms that are widely distributed in surroundings can have complicated interactive reactions with metallic materials. The microbiologically influenced corrosion (MIC) has caused serious economic losses and resource wastage for human society. To date, great efforts have been made in the mechanism of MIC and control methods. This work describes the research findings on MIC developed in the recent years, and studies on the common microbial species that affect metal corrosion. The other aim of this paper is to review the accelerating or inhibiting mechanism in metal corrosion. Also, it provides an outlook for research on MIC.

Published: February 2022

Abstract
The phase equilibria of the Mo–Si–V ternary system were experimentally determined, including the isothermal sections at 1200 and 1450 °C, as well as the liquidus surface projection. The microstructures, crystal structures and phase constitutions of the as-cast and the annealed alloys in whole composition range were investigated by means of scanning electron microscopy equipped with energy dispersive spectroscopy, electron probe microanalyzer and X-ray diffraction. Five three-phase regions and ten two-phase regions were confirmed and no ternary compounds were observed in isothermal sections at 1200 and 1450 °C. In addition, the solidification paths of different Mo–Si–V alloys were analyzed to verify the primarily solidified phases. The stoichiometric compounds Mo5Si3 and V5Si3 have the same structure-type (W5Si3), however, they have two different compositions in the Mo–Si–V ternary system. They form two-line compounds Mo-rich Mo(V)5Si3 and V-rich V(Mo)5Si3. Eight primary solidification regions were finally confirmed on the basis of the study on the solidification processes of the as-cast alloys. The present experimental results are useful for the thermodynamic assessment of the Mo–Si–V ternary system, and the database development for the multi-component Nb/Mo–Si-based superalloy system.
Power allocation scheme in MIMO-OFDM UWOC system with varying receiver spacing channel gain analysis
Authors: Bai Jurong , Nie Jing , Yang Yi , He Fengtao , Zhao Feng 
Published: February 2022

Abstract
For underwater blue–green light multiple-input multiple-output orthogonal frequency division multiplexing modulation system (MIMO-OFDM), the underwater MIMO channel gain matrix corresponding to the change of receiver spacing was analyzed and derived, and a proportional power allocation scheme combined with singular value decomposition (SVD) precoding was proposed, in order to eliminate inter-channel interferences of the MIMO system. The simulation results show that when the transmitter spacing is fixed, and the receivers adopt the same spacing as the transmitters, which is difficult to achieve in the complex underwater environment, the system bit error rate (BER) performance under the proposed proportional power allocation scheme is the same as that of the average power allocation. When the receiver spacing increases, the system BER under the proposed scheme can ensure better overall performance compared with that of the traditional average allocation scheme.

Published: February 2022

Abstract
Light’s orbital angular momentum (OAM) with inherent mode orthogonality has been suggested as a new way to the optical encryption. However, the dependence of annular intensity profiles on the topological charge complicates nanoscale light–matter interactions and hampers the ultra-secure encryption application. In this paper, we demonstrate ultra-secure image encryption by tightly focusing perfect optical vortex (POV) beams with controllable annular intensity profiles and OAM states. A simple scheme composed of single spatial light modulator to implement Fourier transform of an ideal Bessel mode with both amplitude and phase modulations is proposed to generate radius-controllable POV in tightly focused beams. Such focused POV beams with identical intensity profiles but varied local OAM density are applied to disorder-coupled gold nanorod aggregates to selectively excite electromagnetic hot spots for encoding information through photothermal deformation. As such, ultra-secure image encryption in OAM states of POV beams in combination with different polarizations can be achieved. Our results lay the ground for diverse nanophotonic applications harnessing the OAM division of POV beams.

Abstract
Cerium oxide nanoparticles have unique catalytic and oxygen storage capacity properties. In this work, the morphology and size of cerium oxide nanoparticles were experimentally and theoretically investigated. For the synthesis of nanoparticles, the laser ablation method was used. The analysis of the size and morphological characteristics of nanoparticles was performed using transmission electron microscopy. Using the method of molecular dynamics, we reveal the limiting dimensional transition from octahedral morphology to a spherical form in cerium oxide nanoparticles. The results obtained will be relevant for the controlled synthesis of nanostructured materials based on cerium oxide.

Published: February 2022

Abstract
Magnesium-based composites are promising materials that can achieve higher strength, modulus, stiffness, and wear resistance by using metals, ceramics, and nanoscale carbon-based materials as reinforcements. In the last few decades, high-performance magnesium-based composites with excellent interfacial bonding and uniformly distributed reinforcements have been successfully synthesized using different techniques. The yield strength, Young’s modulus, and elongation of SiC nanoparticle-reinforced Mg composites reached ∼710 MPa, ∼86 GPa, and ∼50%, respectively, which are the highest reported values for Mg-based composites. The present work summarizes the commonly used reinforcements of magnesium composites, particularly nano-reinforcements. The fabrication processes, mechanical properties, reinforcement dispersion, strengthening mechanisms, and interface optimization of these composites are introduced, and the factors affecting these properties are explained. Finally, the scope of future research in this field is discussed.

Published: February 2022

AbstractThe spread of disinformation about science in social media has been a major concern worldwide, especially at a time of crisis in which all institutions that produce knowledge and truth, including science, are delegitimized or discredited by society. Given this, the purpose of this research is to map the circulation of information on the most frequent conspiracy theories in Brazil, seeking to identify actors, discourses, and interactions on different digital platforms. Using a mixed methodology for identifying informational flows among supporters of conspiracy theories on Facebook, WhatsApp, and YouTube, the results show that, even though there is distrust about the relationship between science, government and industry, scientific authority is a symbolic capital of extreme importance for the circulation of information on conspiracy theories related to science.

Published: February 2022

AbstractThis study investigates the physicochemical and thermal properties of styrene–butadiene rubber (SBR) nanocomposite foam. Nano-calcium carbonate (CaCO3) was prepared from eggshells (ESs) waste. Sponge rubber nanocomposites were prepared and were irradiated by electron beam (EB) radiation at 25, 75, and 150 kGy. Their physicochemical properties, including foam density, compression set (CS), hardness, abrasion loss, and expansion ratio, and their thermal stability were investigated. The physicochemical properties were enhanced by adding 2.5 phr of a foaming agent. Among the composites examined, the foam composites containing nano-CaCO3had the lowest CS, abrasion loss, and expansion ratio and the highest hardness and foam density. The results confirmed that the thermal stability was improved by incorporating nano-CaCO3into the SBR foam and as the radiation dose increased. The sponge containing nanoclay demonstrated an intermediate behavior, whereas that with CaCO3nanoparticles showed low average cell diameter and size and high cell wall thickness. The radiation process enhanced the foam density, CS, abrasion loss, hardness, and thermal property of the developed nanocomposites by inducing the formation of intermolecular crosslinks within the composite matrix.The results showed that physicochemical properties improved by increasing the radiation dose at 25 kGy.

Abstract

Objectives
Left ventricular thrombus is regarded as one of the main myocardial infarction complications. Knowing the left ventricular thrombus symptoms prevents serious complications that may occur. This study aims to reveal any association between SCUBE-1 and left ventricular thrombus, thought to be involved in platelet aggregation and adhesion.

Methods
The study included 80 patients diagnosed with heart failure following acute myocardial infarction, applying for the cardiology outpatient clinic for third-month follow-up. The patients were included in two groups to see if the left ventricular thrombus was present. Thus, 22 patients were found to have left ventricular thrombus. The two groups were compared based on clinical laboratory and echocardiographic parameters.

Results
It was found that the patients with left ventricular thrombus had significantly higher Serum SCUBE-1 levels (p<0.001). The optimal cutoff point of SCUBE-1 levels for predicting the LVT was >35.1 ms, with the specificity of 86% and sensitivity of 68.4% (AUC=0.815; 95% CI, 0.699–0.931; p<0.0001). SCUBE -1 level (OR=1.090, 95% CI: 1.034–1.150, p<0.001) in the multiple logistic regression model continue to significantly predict LVT after adjusting for the confounding variables, as statistically significant in the univariate analysis of the variables which correlated with the SCUBE-1 levels.

Conclusions
SCUBE-1 level was determined to independently predict the left ventricular thrombus after a previous anterior myocardial infarction.

Published: February 2022

Abstract

Objectives
The consumption of popular tobacco products has adverse effects on public health. Early diagnosis and treatment practices are essential based on the disease-symptom relationship in public health problems. There is a need to evaluate biochemical parameters to elucidate the pathophysiological mechanisms of these problems with experimental studies. We aimed to investigate the biochemical and physiological effects of cigarettes, hookahs, and electronic cigarettes (e-cigarettes) that people commonly use.

Methods
We have used Wistar albino rats, and the rats were exposed to cigarette smoke, e-cigarette smoke, and hookah smoke for 60 min/day for seven days. We detected malondialdehyde (MDA), nitric oxide (NOx), protein carbonyl oxidation (PCO), 8-hydroxy-2′-deoxyguanosine (8-OHdG), total antioxidant status (TAS), total oxidant status (TOS), reduced glutathione (GSH), and superoxide dismutase (SOD) levels in blood samples taken after the experiment.

Results
We observed that the redox balance was disturbed in all groups. E-cigarettes mainly triggered lipid peroxidation; only hookah activated the intracellular antioxidant system.

Conclusions
Cigarette, hookah, and e-cigarette smoking should be considered high-risk factors for individual and public health. The use of tobacco products adversely affects public health.

Abstract
Sandau, I and Granacher, U. Long-term monitoring of training load, force-velocity profile, and performance in elite weightlifters: a case series with two male Olympic athletes. J Strength Cond Res 36(12): 3446–3455, 2022—The aim of this case series approach was to analyze weekly changes in force-velocity relationship (FvR) parameters (v̅
0, F̅
0, P̅
max) and theoretical snatch performance (snatch
th) assessed through a specific snatch pull test in preparation of the European and World Championships in 2 male elite weightlifters. A second aim was to examine associations of training load (volume, volume load, average load), barbell FvR-parameters, and snatch
th over a period of 2 macrocycles in preparation of the same competitions. FvR-parameters, snatch
th, training load data, and body mass were assessed weekly over 40 weeks. Using the smallest real difference approach, significant (p ≤ 0.05) decreases in v̅
0 and increases in F̅
0, P̅
max, and snatch
th were found within macrocycles. However, the large significant loss in body mass (≈11%) in athlete 1 during macrocycle 2 represents most likely a main factor for diminished P̅
max, and snatch
th in macrocycle 2. Based on cross-correlation analyses, barbell FvR-parameters and snatch
th were significantly (p ≤ 0.05) associated with maximal strength, muscle power, and speed training load variables. Moderate correlations (0.31–0.47) were found between training load and P̅
max and snatch
th in athlete 2. It can be concluded that the applied training loads elicits improvements in P̅
max and snatch
th because the athlete approached the main competitions. However, because of the large loss in body mass, the relations between training load and barbell FvR-parameters and snatch
th were less clear in athlete 1. It seems that a loss in body mass as a result of a change in bodyweight category mitigates P̅
max development during the macrocycle and hindered to reach peak snatch
th at the main competitions.
