Acalypha indica mediated mgO NPs: a novel approach in greener route with its antibacterial activity against pathogens


 
 
 The interest in miniaturization of particles revealed the hidden applications of metal oxides. The potential applications of the particles may vary when the size of the particle is reduced. One of the alternative routes to the conventional approach is the use of plant extract for the synthesis of metal oxides NPs. In the framework of this study, the ecofriendly MgO nanoparticles were synthesized using Acalypha Indica leaf extract,functioning as reducing and capping agent by co-precipitation method. The predecessor taken here was Magnesium Nitrate. The biologically synthesized MgO NPs were characterized by various techniques like X ray diffraction(XRD), Fourier Transform infrared spectroscopy(FTIR), Scanning electron microscope (SEM) with Energy Dispersive X-ray spectroscopy(EDX) profile and its antibacterial activity is evaluated against causative organisms. XRD studies confirmed the face centered cubic crystalline structure of MgO NPs and the average crystalline size of MgO NPs calculated using Scherer’s formula was found to be 13 nm. FTIR spectrum shows a significant Mg-O vibrational band. Purity, surface morphology and chemical composition of elements were confirmed by SEM with EDX. The SEM result shows the fine spherical morphology with the grain size range between 43nm to 62nm. Antimicrobial assay of MgO NPs was examined against gram positive and negative bacteria. Appreciated activity was observed on the Staphylococcus aureus bacterial species. In general, the renewed attempt of this facile approach gave the optimum results of multifunctional MgO NPs.
 
 

High-throughput simulation combined machine learning search for optimum elemental composition in medium entropy alloy

In medium/high entropy alloys, their mechanical properties are strongly dependent on the chemical-elemental composition. Thus, searching for optimum elemental composition remains a critical issue to maximize the mechanical performance. However, this issue solved by traditional optimization process via “trial and error” or experiences of domain experts is extremely difficult. Here we propose an approach based on high-throughput simulation combined machine learning to obtain medium entropy alloys with high strength and low cost. This method not only obtains a large amount of data quickly and accurately, but also helps us to determine the relationship between the composition and mechanical properties. The results reveal a vital importance of high-throughput simulation combined machine learning to find best mechanical properties in a wide range of elemental compositions for development of alloys with expected performance.

Structural, chemical and electrochemical studies of bismuth oxide thin films growth via Unbalanced Magnetron Sputtering

A study on the physical, chemical and electrochemical (properties) behavior of bismuth oxide thin films is presented in this work. Thin films were grown on 316 L stainless steel substrates via Unbalanced Magnetron Sputtering (UMS) in reactive phase, varying the DC power applied to the target between 20 and 80 W with 10 W step, keeping the gases flow constant at 9 sccm and the Ar/O2 ratio at 80:20. X-ray diffraction analysis was carried out for the structural characterization, showing that the crystallinity of the films strongly depends on the power of the discharge. The elemental chemical composition was determined using the Rutherford Backscattering (RBS) technique, making it possible to observe that the films were composed by a mixture of crystalline bismuth and possibly amorphous bismuth oxide. With this technique, the thickness of the coatings was measured, observing that this parameter increased from 200 to 700 nm as power values increased. Finally, the electrochemical analysis showed that corrosive behavior depends on the sample growth conditions and coatings thickness.

It has been demonstrated that the correlated barrier hopping (CBH) and non-overlapping small polaron tunneling (NSPT) conductions take place in the LaCr0.99Pd0.01O3 compound.

The influence of environmental factors on the indicators of biological systems of dairy cows in anthropogenic zone conditions

The negative environmental situation in such a region of the Russian Federation as the Chelyabinsk region is due to the prolonged and intense impact of man on nature. The Magnitogorsk Iron and Steel Works (MMK) and other large industrial enterprises operate in the region. MMK is one of the leading global steel producers. This is one of the largest Russian enterprises in the metallurgical industry. The article presents the results of the analysis of the chemical composition of objects related to the natural environment of the region. A significant level of toxic effects on biological objects was noted. These objects are lactating cows. Pathomorphological, radiological, and clinical-hematologic features inherent in osteodystrophy are characterized. Based on these factors, a characteristic of the necessary therapeutic effect is presented. The results of the study of the clinical condition, blood serum and blood of twenty-four cows, water, feed, soil are presented. The study was conducted in the Nagaybak district of the region, in the Znamensky agricultural enterprise. The results of the analysis of the composition of chemical elements, such as Cd, Fe, Pb, Ni, presented in the bone tissue of animals suffering from the disease, and in other objects of research are characterized.

Lead in hair coat of farm animals in the area tailing dump of Khapcharanginsky ore-dressing and processing enterprise

Currently, in the development of the biosphere there is an active evolution of the chemical element composition of matter, due to the anthropogenic load on the natural environment and an increase in the migration of technogenic elements. Scientists have been noted that the leading cause of degradation of the geochemical environment in the Trans-Baikal Territory is the development and exploitation of mineral deposits. For more than three centuries of activity of the mining and industrial complex in Trans-Baikal Territory, areas of technogenic landscapes have been formed, characterized by newly formed geochemical anomalies of toxic elements that have the negative influence on the environment and public health. One of these is the Khapcharanginsky ore-dressing and processing enterprise. The residential stock of the village is located at a distance of 50–100 m from the storage of industrial waste, and some garden plots are directly adjacent to the object. The purpose of the researches is to determine the lead content in the hair coat of farm animals in the area of the tailing dump of Khapcharanginsky ore-dressing and processing enterprise. The research material has been collected in private farms in the village of Khapcheranga in the Kyrinsky area in the Trans-Baikal Territory. Hair samples from cattle (aged 12 months and 3 years) and sheep (ages 1 and 2 years) have been cut from the tip of the tail weight per 10–20 g (n=9). The brief information about lead as an environmental pollutant has been provided in the article. In the studied animals the level of lead in the hair increases. Thus, in cattle with age it increases by 2,2 and in sheep by 1,2 times. The high concentration of this element in the hair coat of animals is associated with the topography of sampling (brush tail) and of course with the habitat of animals directly near the storage of industrial waste.

Synthesis of multifunctional chlorhexidine-doped thin films for titanium-based implant materials.

Our goal was to create bio-functional chlorhexidine (CHX)-doped thin films on commercially pure titanium (cpTi) discs using the glow discharge plasma approach. Different plasma deposition times (50, 35 and 20min) were used to create bio-functional surfaces based on silicon films with CHX that were compared to the control groups [no CHX and bulk cpTi surface (machined)]. Physico-chemical and biological characterizations included: 1. Morphology, roughness, elemental chemical composition, film thickness, contact angle and surface free energy; 2. CHX-release rate; 3. Antibacterial effect on Streptococcus sanguinis biofilms at 24, 48 and 72h; 4. Cytotoxicity and metabolic activity using fibroblasts cell culture (NIH-F3T3 cells) at 1, 2, 3 and 4days; 5. Protein expression by NIH-F3T3 cells at 1, 2, 3 and 4days; and 6. Co-culture assay of fibroblasts cells and S. sanguinis to assess live and dead cells on the confocal laser scanning microscopy, mitochondrial activity (XTT), membrane leakage (LDH release), and metabolic activity (WST-1 assay) at 1, 2 and 3days of co-incubation. Data analysis showed that silicon films, with or without CHX coated cpTi discs, increased surface wettability and free energy (p<0.05) without affecting surface roughness. CHX release was maintained over a 22-day period and resulted in a significant inhibition of biofilm growth (p<0.05) at 48 and 72h of biofilm formation for 50min and 20min of plasma deposition time groups, respectively. In general, CHX treatment did not significantly affect NIH-F3T3 cell viability (p>0.05), whereas cell metabolism (MTT assay) was affected by CHX, with the 35min of plasma deposition time group displaying the lowest values as compared to bulk cpTi (p<0.05). Moreover, data analysis showed that films, with or without CHX, significantly affected the expression profile of inflammatory cytokines, including IL-4, IL-6, IL-17, IFN-y and TNF-α by NIH-F3T3 cells (p<0.05). Co-culture demonstrated that CHX-doped film did not affect the metabolic activity, cytotoxicity and viability of fibroblasts cells (p>0.05). Altogether, the findings of the current study support the conclusion that silicon films added with CHX can be successfully created on titanium discs and have the potential to affect bacterial growth and inflammatory markers without affecting cell viability/proliferation rates.

Zinc concentrations in the expressed prostatic fluid of patients with bladder cancer

Introduction: In our previous studies it was concluded that the zinc (Zn) level in in human expressed prostatic fluid (EPF) is a first candidate with the role of offering a new, simple, fast, reliable, and non-invasive diagnostic tool for prostate cancer (PCa) screening. However it was unclear how other non-prostatic diseases inherent of the old persons, including heart diseases, atherosclerosis, diabetes, asymptomatic cancer of different localization and some others, impact on a chemical element composition of expressed prostatic fluid. Thus, the purpose of this study was to evaluate whether significant changes in the levels of Zn in EPF exist in patients with bladder cancer (BC). Methods: Prostatic fluid levels of Zn were prospectively evaluated in 17 patients with BC and 51 healthy male inhabitants (control group). Measurements were performed using 109Cd radionuclide-induced energy dispersive X-ray fluorescent microanalysis developed by us. Results: Mean value  standard deviation of mean (MSD) for concentration of Zn in the EPF of healthy males and patients with BC was 573202 mg/L and 625±108 mg/L, respectively. Using both parametric Student’s t-test and non-parametric Wilcoxon-Mann-Whitney U-test it was shown that the Zn concentration in the EPF of patients with BC did not differ from that in healthy subjects. Conclusion: Such serious illness as BC did not impact on the Zn concentration in the EPF.

Utilization of Industrial Solar Cells’ Scrap as the Base Material to Form Coatings

The aim of this research is to find possible ways to recycle and re-use industrial solar cell scrap. The work is concentrated on cells which are broken, damaged or rejected during the manufacturing process, which accounts from 2 to 3 percent of whole production on average. Different chemical methods have been suggested for the recovery of pure valuable elements from damaged or worn cells, while the technology presented in this paper utilizes industrial solar cell scrap to produce secondary value products. Crushed industrial waste of different fraction sizes was analyzed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) methods. Tungsten inert gas welding (TIG) has been chosen as the coating formation process. Proper parameters: current 55 A, voltage 19 V, gas flow rate 5 l/min, torch tilt angle 80–85° were selected experimentally, as parameters of common welding are not suitable for the deposition. The chemical composition and transition of chemical elements towards the substrate showed sufficient adhesion and smooth distribution of elements. Alongside with aforementioned methods, mechanical tests were accomplished, showing that damaged solar cells industrial scrap could be used as a source of alloying elements to compose the coating. The hardness of produced coatings as deposited reached 39 HRC (microhardness 2 GPa) on average. Formed coatings could serve for various applications, however further in-depth research is necessary. As suggested, the wear test method is too aggressive for this type of surface. Nevertheless, coatings based on industrial solar cell scrap showed a mass loss two times lower on average than normalized structural steel S355 substrate in rough abrasive conditions.

Preparation and evaluation of micro-encapsulated thermal control materials for oil well cement slurry

Abstract In the process cementing of deep water, cement particles react with water to produce a lot of hydration heat, which can lead to decomposition of natural gas hydrate. We synthesized a kind of micro-capsule thermal control material with paraffin wax as the base material and calcium carbonate as the skeleton support material. At first, the chemical structure and chemical element composition of thermal control material were obtained by FTIR and EDS, respectively. Secondly, the phase change properties of MPCM-1 were measured by using DSC. As a result, it was shown that phase change temperature and phase change enthalpy of thermal control material is 31.11 °C and 88.59 J/g, respectively. Simultaneously, the thermal stability of IPCM-1 was obtained by using a synchronous thermal analyzer. Then, the micro-encapsulated thermal control material is introduced into the cement slurry system, and the hydration heat and maximum hydration temperature rise of the cement slurry were investigated by a self-made hydration heat test device. As a result, compared with cement slurry CB, the hydration heat released to the environment by cement slurry CS12.0% decreased by 44.16% (at 48 h), and the maximum hydration temperature of cement slurry CS12.0% is reduced by 25.4 °C. Besides, compared with cement slurry CB, the compressive strength of cement slurry CS12.0% increased by 5.9% (24 h) and 9.8% (48 h). The thermal control material was added into the cement slurry, and a low hydration heat cement slurry system was successfully prepared.

Synthesis and characterization of cross-linked epoxy resin beads by suspension polymerization technique

Cross-linked epoxy resin beads (ERBs) in macro size range were synthesized from biphenol diglycidyl ether (DGEBA) epoxy resin by suspension polymerization technique. The polymerization reaction of the epoxy resin with triethylenetetramine (TETA) was conducted in a presence of poly(vinyl alcohol) (PVA) as stabilizing agent at a temperature of 90 ± 2 °C with agitation rate of 800 rpm for 4 h. The amount of PVA was varied from 5 to 12.5 wt.% during the polymerization reaction which has shown a significant effect on the particle size and its distribution. The mean particle size and particle size distribution were evaluated by particle size analyzer. Results showed that the mean particle size increased with increasing the concentration of PVA. The mean particle size of ERB1, ERB2, ERB3 and ERB4 samples obtained at various concentration of PVA i.e. 5.0. 7.5, 10.0 and 12.5 wt.% was found to be 491, 475, 468 and 391 μm, respectively. Chemical structure, surface morphology and elemental composition were investigated through a Fourier Transform infrared spectrometry (FTIR), scanning electron microscopy (SEM) and SEM coupled energy dispersive X-ray spectroscopy, respectively. Thermal stability and kinetic parameters of the ERBs were also examined by a thermogravimetric analysis (TGA) technique. The thermal stability was found in the order of ERB1 ≥ ERB2 > ERB3 ≥ ERB4. The apparent activation energy and pre-exponential factor (A) of pure epoxy resin, ERB1 and ERB4 samples were calculated by applying the Kissinger method through thermogram peak temperature using first derivative thermogravimetric (DTG) data. The values of the activation energies of the pure epoxy resin, ERB1 and ERB4 samples were 235.3, 257.7 and 239.4 kJ/mol along with pre-exponential factor A of 1.0 × 1019, 1.5 × 1019 and 6.8 × 1018 s−1, respectively.

Tracing Palaeolithic human routes through the geochemical characterisation of chert tools from Caune de Belvis (Aude, France)

Caune de Belvis (Aude, France) is located in the northern slopes of the eastern Pyrenees, in south-east France. Excavations at the site during the final decades of the past century identified several human occupations from the Late Mousterian (Maroto et al. 2003) and the Magdalenian periods (Sacchi 1993). The archaeological remains are mostly composed of faunal bones and a rich bone and stone industry. In this paper, we focused on the analysis of stone remains recovered in the Magdalenian levels. The goals of this study are to determine the territorial behaviour of Magdalenian groups settled at Caune de Belvis and to identify their lithic procurement strategies. To do so, we applied a range of techniques for analysing stone remains from the Magdalenian levels and geological samples from the geological formations that may have been used. First, macroscopic studies were carried out to determine the textural and micropalaeontological content; then, geochemical analyses were conducted to quantify the elemental chemical composition. Energy-dispersive X-ray fluorescence (ED-XRF) was used to quantify major and minor elements and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was then used to quantify trace elements. The results show that the Magdalenian groups from Caune de Belvis exploited a range of geological formations in the northern and southern Pyrenees. They also highlight the relationship existing between the two sides of the Pyrenees during the Upper Palaeolithic and bear witness to the inhabitants’ thorough knowledge of the Pyrenean area.

Shannon Entropy as an Indicator for Sorting Processes in Hydrothermal Systems.

Hydrothermal processes modify the chemical and mineralogical composition of rock. We studied and quantified the effects of hydrothermal processes on the composition of volcanic rocks by a novel application of the Shannon entropy, which is a measure of uncertainty and commonly applied in information theory. We show here that the Shannon entropies calculated on major elemental chemical composition data and short-wave infrared (SWIR) reflectance spectra of hydrothermally altered rocks are lower than unaltered rocks with a comparable primary composition. The lowering of the Shannon entropy indicates chemical and spectral sorting during hydrothermal alteration of rocks. The hydrothermal processes described in this study present a natural mechanism for transforming energy from heat to increased order in rock. The increased order is manifest as the increased sorting of chemical elements and SWIR absorption features of the rock, and can be measured and quantified by the Shannon entropy. The results are useful for the study of hydrothermal mineral deposits, early life environments and the effects of hydrothermal processes on rocks.

The effect of cryogenic applications on tensile strength of aluminum 2219-T87 T-joint welded by dual laser-beam bilateral synchronous welding

2219 aluminum alloy has been widely used in aerospace industry due to its high specific strength, excellent weldability as well as outstanding ductility. The dual laser-beam bilateral synchronous welding (DLBSW) technology is employed in the joining of 2219-T87 aluminum alloy skin-stringer structure in T-joint. In order to establish the tensile strength of T-joints at room and cryogenic temperatures, the tensile testing is carried out. The microstructure of weld seam is observed for exploring the relationship between the grain size and tensile strength. In addition, the fracture morphology is observed by scanning electron microscope (SEM). The elemental analysis of fractured surface is done by energy dispersive spectrometer (EDS) and is used to study the effect of chemical element composition on tensile strength. The results show that the highest tensile strength of 360.01 MPa was achieved when the tensile test obtained at room temperature while the joint welded by same parameter exhibit a much higher tensile strength of 422 MPa when tested at cryogenic temperature. According to the results of microstructure analysis, grain size reduction was observed when the joint was exposed to cryogenic temperature. From the fracture morphology of joints, it was found that dimples of the sample tested at cryogenic temperature are bigger and deeper than that at room temperature. The results of EDS show that the amount of the Al2Cu increases at 77 K which causes an increase in tensile strength.

The Electrical Performance of Microvaristor Composites at Different Filler Loadings

Resistive field grading materials is deliberately gaining attention since it shows better performance in steering uniformly electrical properties of high voltage equipment compared to conventional machinery techniques. The key point of these extraordinary materials because its electrical properties that can be tuneable according to material characteristics, composition of chemical elements in the host matrix and significantly influenced from fabrication process. In this research, microvaristor composite was added with silicone rubber at different weight percentage (wt. %) with dimension 50 mm x 50 mm x 5 mm. The selection of this material because it is more robust and less sensitive to a variety parameters such as pressure and humidity. The samples were examined under power frequency voltage at 50 Hz. The experimental results were analysed using Point on Wave (POW) technique and electrical properties for all samples were evaluated at highest applied voltage, 5 kV.

Silicon in the fight against opportunistic skin infections (experimental and clinical studies)

The article presents the results of chemical, clinical and experimental studies of siliceous solutions. The results of the study showed that siliceous solutions, due to the chemical composition of medicinal minerals and REE elements, contribute to the enrichment of the chelating protein calprotectin in neutrophils, which further inhibits the growth of mixed bacterial and viral microorganisms, which leads to anti-infection efficiency.

Dry mechanical-electrochemical polishing of selective laser melted 316L stainless steel

This paper aims to improve the surface quality of 316L stainless steel parts manufactured by selective laser melting (SLM) using dry mechanical-electrochemical polishing (DMECP). DMECP is an advanced surface finishing method combining the advantages of both mechanical and electrochemical polishing techniques in a more environmentally friendly manner. In this paper, the SLM process-related defects causing poor surface quality are analysed first. The material removal mechanism of DMECP is investigated to continuously remove the oxide layers formed during polishing. Surface morphology and roughness evolution under different polishing conditions are characterised. The top surface roughness can be reduced by over 91% from 8.72 μm to 0.75 μm compared to side surface by over 93% from 12.10 to 0.80 μm. The material removal on the top surface is more efficient than that on the side surface under the same polishing condition. The secondary defects formed during polishing can be removed using mechanical polishing mode. The chemical element composition of the polished surface exhibits almost identical content to the initial 316L powders. Compared with the initial dark and rough surfaces, the results validate the capability of DMECP as an effective tool to improve the SLM surface quality and achieve a mirror finish.

Chemical parameters of gourmet salts compared withsalt extracted from eichhornia crassipes evaluated by energy-dispersive x-ray spectrometry

Salts have been part of human nutrition since 2,000 b.C., having originated in the Zhongba region, in China. Itssubstantial availability in food markets and stores specialized in condiments led us, curiously, to compare its elemental chemical composition with that of salt extracted from a floating aquatic macrophyte, known commonly as “water hyacinth” (Eichhornia crassipes), whose product, after extraction from dry matter, was popularly denominated“indigenous salt”. The objective of the present study was to evaluate the chemical composition of gourmet salts in comparison with indigenous salt using the energy-dispersive X-ray spectrometry (EDX) technique. Eichhornia crassipes exhibited higher concentrations of chloride (35.834%), potassium (62.146%), sulfur (1.095%), calcium (0.450%), bromine (0.177%), silicon (0.124%), copper (0.029%), magnesium (0.123%), and rubidium (0.023%) than the gourmet salts. Our results indicate that this indigenous salt should be consumed under medical guidance due to its high concentration of potassium chloride, a salt whose properties are used for specific human treatment and not daily consumption.

Process Performance Analysis and Improvement for the Manufacture of 6063 Aluminum Alloy

As industrial manufacturing technologies continuously improve, many conventional industrial materials are struggling to meet the needs of today’s industries. Aluminum alloys are currently the most extensively used non-ferrous metal in the industry, whose properties include corrosion resistance, high strength, and high ductility. As a result, they are widely used in many products, such as doors and windows, vehicles, and electronics. Pure aluminum though, is a very soft, silver-white metal, so to increase its strength, aluminum alloy manufacturers add in various chemical elements (such as magnesium, silicon, and zinc) according to international standards, and then adjust the proportions based on customer needs. If the chemical element composition does not meet specification requirements, it will affect the quality of the aluminum alloy product or even delay delivery and subsequently impact the operational performance of the manufacturer. To ensure and increase aluminum alloy quality, this study used a combined Six Sigma quality index (SSQI), Qpc, to develop a multi-characteristic quality analysis model (MCQAM) with five steps for the aluminum alloy industry. A practical example with a manufacturer specializing in producing 6063 aluminum alloys in Taiwan is given to demonstrate the effectiveness and feasibility of this proposed approach. The result shows that the proposed method not only effectively improves the quality of 6063 aluminum alloy, but also enhances its performance and capability (that is, corrosion resistance increases by 17%, strength increases by 8%, and stiffness increases by 3%). Finally, future works are also discussed in this context.

Intensification and monitoring by Raman spectroscopy of parboiling process

Although parboiling is dependent on a hydration step, knowledge of the paddy rice characteristics during this stage is lacking. This study aimed to identify changes in the morphological structure of starch during hydration, as well as the elementary chemical composition of the grain. In addition, water absorption kinetics was adjusted and simulated by mathematical models. Concentration gradient, temperature, and physical properties of paddy rice influenced mass transfer during hydration. Certain hydrothermal conditions promoted an irreversible disorganization in molecules of starch (crystalline structure to amorphous), which characterized its gelatinization and the parboiling of paddy rice. The hydrothermal conditions altered the intensity of excitation of the chemical groups identified, what suggests the Raman technique as a potential method of monitoring moisture. The application of this information reduces costs of industrial processes. Furthermore, mathematical modeling can also be used as a process control tool, reducing the need for experimental tests. Practical applications This study allowed the characterization of moisture transfer in the hydration stage of paddy rice parboiling process. From the collected data, it was possible to affirm that parboiling of paddy rice takes place during hydration when the right conditions are use. Then, there would be no need for later steps, reducing costs for the industries and providing the process intensification. In addition, the Raman technique is suggested as a possible alternative method for moisture monitoring and mathematical modeling as a tool for process optimization, since it is able to predict and simulate water gain in the hydration step, eliminating the need for experimental tests.
