After plasma spraying, high‐velocity‐oxy‐fuel (HVOF) spraying is fast emerging as the most versatile deposition technique for thermal sprayed protective coatings. In this context, the present work aims at the deposition of a class of inter‐metallic/cermet coatings of nickel chrome boron silicium (NiCrBSi) and nickel chrome boron silicium+titanium diboride (TiB2) on 304 stainless steel substrates using high‐velocity oxy‐fuel spraying route. The cermet powder is prepared as the feedstock by mechanical mixing of the powders prior to spraying. Different coating samples are obtained by varying the flame‐to‐substrate spray distance (40 mm, 80 mm, 120 mm, 160 mm and 200 mm). These coatings are characterized in terms of their adhesion strength, deposition efficiency, thickness, and micro‐hardness by conducting tests as per the ASTM standards. The surface and interface morphologies of the deposited coatings are studied using scanning electron microscopy. The possible phases present in the coatings, and the transformation of phases during deposition have been explored by x‐ray diffraction analysis. It is found that the coatings exhibit fairly good interfacial adhesion, micro‐hardness, and thickness values that varied significantly with the spray‐distance. Further, the premixing of titanium diboride in nickel chrome boron silicium improved the mechanical and microstructural/compositional properties of the coatings. [ABSTRACT FROM AUTHOR]

The two protagonists of the Jacob narrative (Genesis 25-49), Jacob and Esau, and their respective families constitute the topic of the present article. Using the method of narrative exegesis of Old Testament stories, it examines the way these two figures are characterised. The focus of research is on the principal characters; a subsidiary issue is the way in which families are portrayed in the Jacob narrative. This issue is indissolubly associated with the characterisation of the two principal participants, since such portrayal gives clues about the norms and values which the narrative intends to communicate. The central thesis of this article is that the blessing which flows from Jacob's family is not directly dependant on his character or transformation. Instead, the narrative communicates that God blesses whatever the circumstances. To be a source of blessing is thus a matter of election, not of human evaluation, ability or competence.

The aim is to study the effect of several distinct manufacturing processes, parameters and ingredients on the physical, mechanical and frictional characteristics of brake pad developed using hand lay method (sample 1), brake pad developed using hot compression method (sample 2) and commercial brake pad (sample 3). The non asbestos brake pad samples were compared with the selected commercial brake pad sample using pin on disc test set up. Results showed that friction performances of all three samples were insensitive to water and oil absorption test. Sample 2 had better mechanical properties and greater wear resistance than other two samples which are attributed to use of hot press method of manufacturing the composite and selecting the carbonbased ingredients. Sample 1 maintained high coefficient of friction even though manufactured with the help of hand lay method. Both fabricated brake pads are stable upto the temperature 220 °C without any weight loss and degradation. Brake pad surfaces showed different shape wear debris and plateaus significantly affecting the friction characteristics. Finally, the test results indicated that both fabricated brake pad samples have potential braking characteristics to be used as a brake pad material. [ABSTRACT FROM AUTHOR]

In this study, aluminium-silicon7-magnesium alloy was reinforced with carbide ceramics (silicon carbide and boron carbide) and coke microparticles. The composite samples (S1, S2, and S3) with 4%, 8%, and 12% by weight of silicon carbide and boron carbide microparticles and 8% by weight of coke micro particles respectively, were prepared through the ultrasonic assisted melt-stir casting route. It was observed from the literature that only a few research works reported the cumulative effect of adding these micro-particulate reinforcements within aluminium-silicon7-magnesium alloy. The microstructural evaluation revealed uniform dispersion of particulate reinforcements. Area energy dispersive x-ray spectroscopy scan results proved the presence of the reinforcement particles as heterogeneous phases at distinct zones. The samples undergone tensile tests failed under the brittle fracture mode. The ultimate tensile strength of the composites improved by about 27.4%, the % elongation improved by about 6.8%, and Vickers microhardness dropped 1.9% to the maximum. Dimples were observed in the fracture morphology analysis and it was mainly due to the mixed ductility of the sample S2. An abrasive wear mechanism was observed in the worn-out sample S2. The wear rate decreased significantly with an increase in weight fraction of the reinforcements. [ABSTRACT FROM AUTHOR]

Growing population, industrialization, urbanization, etc. are the consequences of increasing plastic waste, which is deteriorating the environment's health. The study explores the potential of waste plastics as a value‐added material. The composite samples of floor tiles were developed using 50 wt. %, 60 wt. %, 70 wt. % and 100 wt. % of low‐density polyethylene and sand. The developed samples were evaluated for water absorption, compressive strength, flexural strength, sliding wear, and friction coefficient. The water absorption decreases gradually with replacements. The ranges for compressive and flexural strength were found to be 37.24×10−6 N/m2 to 46.20×10−6 N/m2 and 4.81×10−6 N/m2 to 6.24×10−6 N/m2 respectively having maximum values of 46.20×10−6 N/m2 and 6.24×10−6 N/m2 respectively, for 50 wt. % of low‐ density polyethylene. The incorporation of sand improves the wear performance at moderate to high loads. The friction coefficient depends on load and surface asperities. The structural analysis showed that the fillers are completely encapsulated and mechanically bonded into the matrix. The morphological analysis of the surfaces correlates the fracture mechanism with the properties of the composites. [ABSTRACT FROM AUTHOR]

The article describes the use of VITA AKZENT LC composite paint for the customization of prosthesis bases. Previously, prosthesis bases were monochromatic, but with the light-curing paint, individual color effects can now be reproduced on composite, polymer, and hybrid ceramics. The article demonstrates, using a lip shield, how the colors are applied and what effects can be achieved. The composite paint offers a variety of possibilities to create natural color effects and can be used in various workflows. [Extracted from the article]

Im Wesentlichen hat die retikuläre Chemie die Präzision und Expertise der organischen und anorganischen Synthese auf den festen Zustand übertragen. Während die anfängliche Aufregung über Metall‐organische Gerüstverbindungen (MOFs) und kovalente organische Gerüstverbindungen (COFs) zweifellos durch ihre beispiellose Porosität und Oberfläche befeuert wurde, war die tiefgreifendste wissenschaftliche Innovation des Feldes die Ausarbeitung von Designstrategien für die Synthese von erweiterten kristallinen Festkörpern durch starke gerichtete Bindungen. In diesem Aufsatz beleuchten wir die verschiedenen Klassen von retikulären Materialien, die entwickelt worden sind, wie solche Gerüstverbindungen funktionalisiert werden können und wie Komplexität in ihr Grundgerüst eingeführt werden kann. Schließlich zeigen wir, wie die strukturelle Kontrolle über diese Materialien von der molekularen Skala über ihre Kristallmorphologie und Form auf der Nanoskala bis hin zu ihrer Gestaltung auf der Bulk‐Skala erweitert wird.

In recent decades, the proportion of external thermal insulation composite systems (ETICS) installed in the Federal Republic of Germany has increased significantly due to energy requirements. Currently, there is a significant increase in ETICS waste, for which there is no established recycling strategy. For this reason, in this work ETICS waste was processed in the sense of the circular economy in order to make the secondary raw materials obtained industrially usable. In order to enable targeted recycling and to close the material cycle of ETICS in the long term, particulate properties such as the comminution ratio, sphericity, dispersity as well as the flowability and compressibility of the recyclates were investigated.

Surfactants are very often used in tertiary oil production. However, the conventional surfactants cannot be used in high salinity reservoirs of tertiary oil production because the high salinity leads to the deactivation of the surfactants. Gemini sulpho-betaine surfactants have been developed to meet the requirements of tertiary oil production in such reservoirs. In this study, the Gemini sulphobetaine surfactant (bis{[(N-methyl-N-(3-alkoxy-2-hydroxy)propyl-N-(3-sulfonate)propyl]methylene}) was prepared by etherification, ring opening reaction and sulfonation reaction with decyl alcohol, epichlorohydrin, N,N'-dimethyl ethylene diamine and 1,3-propanesultone. The experimental conditions obtained are: the ratio of 1,3-propanesulfonic acid lactone to tertiary amine intermediate = 2.3: 1, reaction temperature = 70°C and reaction time = 11 h. The analysis of the infrared spectrum showed that the structure of the synthesised substance corresponds to that of a Gemini sulphobetaine surfactant. The chemical shifts of the groups were determined by 1HNMR structural characterisation of the products. The surface tension, emulsifying properties, foaming properties and wetting properties were investigated. The results showed that the surfactant has good foaming properties and good compatibility in a high salt environment. [ABSTRACT FROM AUTHOR]

Turkey is one of the biggest chestnut producers in the world. Most of the chestnut trees found in forests in Turkey and the majority of them are coming from seeds showing huge phenotypic diversity. The study was conducted on naturally growing chestnut trees found in forests belongs to Artvin province located in the northeastern part of Turkey. A total of 22 promising chestnut genotypes previously selected among chestnut populations (Castanea sativa) in 2016 and morphological and biochemical data were collected during 2016 and 2017 harvest season. Morphological parameters were tree growth habit, nut weight, nut size, kernel ratio, and kernel color, respectively. Biochemical characteristics include moisture, crude protein, crude fat, dietary fiber, total carbohydrates, total polyphenols and antioxidant activity of kernels. Results clearly revealed that seed-propagated 22 chestnut genotypes have distinct properties. Average nut weight and kernel ratio varied from 4.38 to 9.19 g; 75.16 to 86.41%. The majority of genotypes were semi-upright growing habit. Total crude fat, crude protein and dietary fiber ranged from 0.87 to 2.61%; 4.80 to 7.65% and 2.06 to 3.61%, respectively. Results indicated that the Artvin region has valuable chestnut genetic resources. [ABSTRACT FROM AUTHOR]

Perfluorooctane sulfonate (PFOS) and its derivatives had been banned due to their potential environmental hazards, although they possessed excellent surface activity. An effective method to solve this problem was to shorten the fluorocarbon chain of these surfactants from C8H17 to C4F9. As previous studies had shown, zwitterionic surfactants possess higher surface activity but have lower toxicity compared to other types of surfactants. In view of this, a class of novel zwitterionic fluorocarbon surfactants (n-CFNA-Br) with perfluorobutyl moiety was synthesized in this work. Their structures were characterized by FTIR, ¹H NMR, 13C NMR, 19F NMR and MS. The results showed that all synthesized n-CFNA-Br had almost the same minimum surface tension, but their critical micelle concentration (CMC) decreased with increasing length of hydrophobic carbon chain. In pure water, the surface tension at the CMC (γCMC) of the four n-CFNA-Br were about 20 mN/m, and the CMC values were 7.73 mmol/L for 1-CFNA-Br, 4.70 mmol/L for 2-CFNA-Br, 4.13 mmol/L for 3-CFNA-Br, and 3.36 mmol/L for 4-CFNA-Br, indicating high efficiency and effectiveness. In 0.1 mol/L NaCl, the CMC values reduced to less than half of the CMC values measured in the pure aqueous surfactant solution, while the surface tensions γCMC remained almost unchanged, indicating good salinity tolerance of the synthesized surfactants. The acidic surfactant solutions exhibited similar CMC values to the saline solutions, but the surface tension γCMC increased slightly to 25 mN/m. However, further investigation showed that the n-CFNA-Br surfactants exhibited poor surface activity in alkaline solution (0.1 mol/L NaOH). In the pH range of 6.6 to 10.4, white precipitates appeared in the surfactant solutions after some time, indicating that the n-CFNA-Br are not suitable for use in alkaline systems with pH greater than 6.6.

This research article investigates carefully the effect of different nanoparticles zinc oxide (ZnO), graphene, and combinations thereof in API base oil group ΙΙ (PBO−GΙΙ). The morphology of zinc oxide and graphene nanomaterials are depicted by transmission electron microscopy. Sonication treatment and dispersion stability investigations are carried out after the preparation of nanoparticles with surfactant (oleic acid) and pure base oil group ΙΙ for certain concentrations. Oil formulations tested by using a four‐ball machine to find out the coefficient of friction (COF), wear scar diameter (WSD), and specific wear rate (SWR) for each sample. Additionally, scarred balls are characterized by using field emission scanning electron microscopes (FE‐SEM), energy‐dispersive x‐ray spectroscopy (EDX/EDS), elements mapping, Raman spectroscopy, and a three‐dimensional surface texture analyzer to study the morphology of sliding balls after the tribological experiments and to confirm the presence of (zinc oxide+graphene) on the machined balls. Surface roughness measurements implemented for identifying surface finish of scarred balls. The experimental results and surface analyses showed that (0.4 wt.% ZnO+0.2 wt.% graphene) nanolubricant has outperformed behavior compared to base oil group ΙΙ due to the formation of tribofilm on the contacting surfaces during sliding motion.

Northeastern part of Turkey is rich in terms of autochthonous grape cultivars. In the region Yusufeli district has special importance for historical cultivation of grapevine. This small district has over fourteen local grape cultivars. Present study describe morphological and biochemical characteristics of nine autochthonous grape cultivars grown in Yusufeli district in Turkey. The standard Turkish grape cultivar 'Cavus' was also included experiment to make comparison with local ones. Bunch size, berry color, berry shape and usage are the searched main morphological characteristics. Phenolic compounds, organic acids, vitamin C and specific sugars were the main biochemical parameters. We found a wide variation among both morphological and biochemical characteristics. The cultivars showed low to medium bunch size. Chlorgenic acid (2.231–4.811 mg/L), syringic acid (1.027–5.426 mg/L) and rutin (1.013–1.129 mg/L) were found the highest content in berries of cultivars. As expected, tartaric acid that characteristic for grape berries was the dominant (ranged from 1.826 to 3.336 g/L) and followed by malic acid (ranged from 1.089 to 2.344 g/L). The all autochthonous grape cultivars had glucose the highest concentration as major sugar and followed by fructose. It can be concluded that morphological and biochemical characteristics analyzed could be useful to give information about selection of the promising grape cultivars for breeders.

Titanium alloy grade 5 is a grade of the titanium material that is in‐demand in the marine, aerospace, biomedical and turbo machinery industries. It offers great properties such as being light weight, good corrosion performance and great strength. However, some of the other properties, namely: its low hardness and poor tribological performance, has limited its various industrial application. Developments have focused on the enhancement of the surface properties without altering the bulk of the material. This has led to the laser metal deposition technique categorized under the additive manufacturing processes. It is a feasible technique that operates on layer‐by‐layer additive processing to manufactures whole parts or repair local damages in components. This study aims to ascertain the optimum processing conditions of the process by varying the laser intensity and scanning speed between 0.9 kW–1 kW and 1.0 m/min–1.2 m/min, respectively, while maintaining all the other process parameters. The specimens were produced by utilizing the ytterbium laser system to conduct laser surface alloying of Ti−Al−Si−Cu/Ti‐6Al‐4 V. Metallographic preparations, characterizations to conduct laser metal deposition (LMD), microhardness and corrosion test were conducted. It was deduced that Ti‐9Si‐3Cu alloy had the best optimum performance at 1 kW and 1.0 m/min. The hardness and corrosion were optimum improved at reduced scan speeds and increased laser power.

Triangulene and its higher homologues are a class of zigzag‐edged triangular graphene molecules (ZTGMs) with high‐spin ground states. These open‐shell molecules are predicted to host ferromagnetically coupled edge states with net spin values scaling with molecular size and are therefore considered promising candidates for future molecular spintronics applications. Unfortunately, the synthesis of unsubstituted [n]triangulenes and the direct observation of their edge states have been a long‐standing challenge due to a high reactivity towards oxygen. However, recent advances in precursor design enabled the on‐surface synthesis and characterization of unsubstituted [3]‐, [4]‐, and [5]triangulene. In this Minireview, we will highlight key aspects of this rapidly developing field, ranging from the principles of precursor design to synthetic strategies and characterization of a homologous series of triangulene molecules synthesized on‐surface. We will also discuss challenges and future directions. [ABSTRACT FROM AUTHOR]

Die gebildete Proteinkorona ist für das Verhalten von Nanoträgern im biologischen System mitverantwortlich. Die Aufklärung der Bildung und des Einflusses der Proteinkorona auf die biologische Antwort ist daher entscheidend. Ergebnisse der Proteinkorona‐Charakterisierung können jedoch nicht ohne Weiteres untereinander verglichen werden, da es zahlreiche verschiedene Verfahren zur Probenvorbereitung gibt, die jeweils für unterschiedliche Materialien und Fragestellungen geeignet sind. Abhängig von der verwendeten Methode wird der Nanoträger‐Protein‐Komplex auf bestimmte Weise verändert, sodass der individuelle Einfluss der Probenvorbereitung auf die Proteinkorona berücksichtigt werden muss. Ziel dieses Kurzaufsatzes ist es daher, einen Überblick über Probevorbereitungsverfahren für die Analyse der Proteinkorona zu geben und ihren Einfluss auf das Ergebnis zu beurteilen, besonders im Hinblick auf die eingeführten Begriffe "weiche" und "harte" Proteinkorona. Im Fokus liegen dabei vor allem die am häufigsten verwendeten Techniken wie Zentrifugation, magnetische sowie chromatographische Trennungen. [ABSTRACT FROM AUTHOR]

Lauryl phosphate monoester was synthesized from the starting materials lauryl alcohol and phosphoric acid without catalysts. Subsequently, the crude product was purified by recrystallization and characterized by Fourier transform infrared (FT-IR) and nuclear magnetic resonance (31P-NMR). From the results, it was apparent that the synthesized material was the desired target product. Lauryl monoester potassium phosphate reduced the surface tension of water to 25.08 mN/m at a critical micelle concentration (CMC) of 0.569 mmol/L. It showed a low contact angle and had a low surface tension, indicating a good hydrophilicity. Lauryl monoester potassium phosphate also showed excellent antistatic properties, however its emulsifying ability was not good. The size of the aggregates of lauryl monoester calcium phosphate in aqueous solution was 220 nm and their morphology was spherical. [ABSTRACT FROM AUTHOR]

Thermal oils are widely used as heat transfer fluids in medium temperature applications. Addition of small amounts of nanoparticles in such fluids can significantly improve their thermophysical properties. This paper presents experimental investigation of an oil‐based nanofluids prepared by dispersing different concentrations (0.25 wt%–1.0 wt%) of copper oxide nanoparticles in Therminol‐55 oil using two‐step method. Shear mixing and ultrasonication were used for uniform distribution and de‐agglomeration of nanoparticles to enhance the stability of the suspensions. The effect of nanoparticles concentrations on thermophysical properties of the nanofluids was analysed by measuring thermal conductivity, dynamic viscosity, effective density and specific heat capacity at different temperatures (25 °C–130 °C). Thermal conductivity exhibited increasing trend with rising temperature and increase in nanoparticles loading. A significant decrease in dynamic viscosity and effective density against increasing temperature makes it suitable for medium temperature applications. Nano‐oils with improved thermal properties are expected to increase the efficiency of concentrating solar thermal collectors. [ABSTRACT FROM AUTHOR]

Sobald Materialien mit einer biologischen Flüssigkeit, die Proteine enthält, in Kontakt kommen, werden Proteine im Allgemeinen – ob gewünscht oder nicht – von der Oberfläche des Materials angezogen und adsorbieren darauf. Das Ziel dieses Aufsatzes ist es, einen Überblick über die am häufigsten verwendeten Charakterisierungsmethoden zu geben, um ein besseres Verständnis der Adsorptionsprozesse auf planaren oder gekrümmten Oberflächen zu erhalten. Wir zeigen weiterhin den Vorteil der Kombination verschiedener Methoden, um auf unterschiedliche Oberflächengeometrien des Materials zuzugreifen. Die so erhaltenen Erkenntnisse ebnen idealerweise den Weg für die Entwicklung funktioneller Materialien, die in einer vorbestimmten Weise mit Proteinen interagieren. Kontrollierte Proteininteraktionen sind für jedes Material in einer biologischen Umgebung erwünscht. Mit einer Kombination von Techniken, die sowohl für gekrümmte als auch für planare Oberflächen entwickelt wurden, können diese Wechselwirkungen charakterisiert und idealerweise das Engineering funktionaler Materialoberflächen ermöglicht werden.

Total phenolic content was the highest as 263 μg GAE/g in LOQ-7 genotype while the lowest in LOQ-8 genotype (185 μg GAE/g). LOQ-7 genotype had the highest total antioxidant capacity. Local genotypes in general have higher total phenolic, total carotenoid, vitamin C and antioxidant activity than cv. 'Sayda'. [ABSTRACT FROM AUTHOR]

The dispersion of carbon nanostructures in metallic matrix with strong bonding is a very important challenge to achieve a composite with high mechanical properties. In this work, the effect of aspect ratio of reinforcement phase, weight percent and using improved mechanical alloying process and sonication on the well dispersion of multiwalled carbon nanostructures (MWCNTs) were investigated. Moreover, the hot pressing conditions were optimized by factorial design technique to achieve the highest relative density. Field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and X-ray diffraction were used to analyse the microstructure. Also, the particle size of the grain structure of composite containing multi-walled carbon nanotubes determined for evaluating the influence of aspect ratio on grain growth. The results verified that by using conventional method of alloying, grinding process and agglomeration of 2 wt% multi-walled carbon nanotubes with long length can be occurred. By decreasing the weight percent of multi-walled carbon nanotubes to 1 wt%, dispersion process progressed slightly. Short length multi-walled carbon nanotubes showed more clustering and minor damage in both 1 and 2 wt%. By using modified design of alloying (using magnet), both types of multi-walled carbon nanotubes dispersed better than conventional design in the matrix with good bonding at initial times.
