Introduction. The authors claim to have originally invented and introduced structural curve-following intumescent fire protection not only for cabling, but also for civil structures of investment construction projects (also those of buildings and facilities of the oil&gas complex since the operation of the structures…
Glauconite is a potassium (K) bearing mineral, which generally contains 6–10% K2O and mostly available in various natural deposits in India. Glauconite mineral was converted to nano-particle form by grinding in a high-energy ball mill. The release of K from glauconite nano-particle in soil was studied in a pot culture…
This study is examined the effects of modified epoxy (EP) coatings with various contents of reduced graphene oxide (RGO) in oil and gas production environments with high-temperature and high-salinity on the long-term service performance of N80 steel. The fracture surfaces of RGO-modified EP coatings were characterized…
The corrosion behaviour of high-strength low-alloy AISI 4135 steel was studied in the presence of homoacetogenic bacteria ( Blautia coccoides GA-1), which catalyse the formation of acetate from H 2 plus CO 2 in their energy metabolism. In addition, the effects of cathodic protection were studied. The chronoamperometry…
A typical solvothermal method was used to synthesize the imidazole framework (Zn-Ni(MeIm) 2 ) and subsequently calcined under a nitrogen atmosphere (Zn-Ni(MeIm) 2 (N 2 -723K), and activated with KOH (Zn-Ni(MeIm) 2 (KOH)). The samples were characterized by X-ray diffraction, field emission scanning electron microscopy,…
Abstract Within the field of electrografting with aryldiazonium cations, there are various methods available to graft a monolayer of organic groups onto electrode surfaces. One of these relies on the presence of steric groups or constraints on the aryldiazonium cation itself, which prevent multilayers from being forme…
Due to the growing market and the relatively high price of poly(lactic acid) (PLA), the possibility to recycle PLA has attracted a tremendous attention, aiming to reduce the environmental impact related to the life cycle of PLA‐based products. However, the comprehensive structural and properties changes of PLA and PLA…
In this work, Langmuir monolayers based on poly(ethylene glycol)–poly(propylene glycol)–poly(ethylene glycol) (PEG–PPG–PEG) triblock copolymer were in situ stabilized at the air–water interface in the presence of a cross-linking agent, benzene-1,3,5-tricarboxaldehyde (BTC), in the aqueous subphase. The reaction takes…
Abstract We studied thermo-optical property degradation of indium tin oxide (ITO)-coated aluminized polyimide thin films under exposure to vacuum ultraviolet radiation and low-energy (3 and 5 keV) protons during ground tests using the Complex Irradiation Facility at the DLR site in Bremen. Changes in solar absorption…
Synergistic effect of rare earth salts conversion coating with phytic acid conversion coating was studied. Rare-earth salts were used as post-treatment to modify the phytic acid coated steel. The corrosion resistance properties of different coatings was investigated with electrochemical impedance spectroscopy in 3.5 w…
This paper describes achievements of the All-Russian Scientific Research Institute of Aviation Materials in the field of creating high-temperature heat-shielding, ceramic and metal-ceramic composite materials. The advantages and prospects of applying the developed materials in the manufacturing of structural elements…
The expectation that composites fabricated with nanoscale reinforcing materials will exhibit exceptional mechanical properties remains to be fulfilled. Here, octaisobutyl‐polyhedral oligomeric silsesquioxane (buPOSS) nanochemical was melt blended with low‐density/linear low‐density polyethylene (LDPE/LLDPE) to form na…
Devices relying on reversible ion intercalation are used in sustainable energy technology, for example, in batteries, in rechargeable electrical and electrochromic (EC) glazing for energy efficient buildings. Degradation of electrochromic thin films under extended charge insertion/extraction is a technologically impor…
Different morphologies of vertically aligned ZnO nanostructures were synthesized onto graphene oxide (GO) coated indium thin oxide (ITO) electrode by electrochemical technique and considered for supercapacitor application. The morphology of ZnO nanowires were successfully transformed and controlled into other morpholo…
Aim: This study aimed to explore an affordable technique for the fabrication of Chitosan Nanoshuttles (CSNS) at the ultrafine nanoscale less than 100 nm with improved physicochemical properties, and cytotoxicity on the MCF-7 cell line. Background: Despite several studies reported that the antitumor effect of CS and CS…
The minimally processed vegetable (MPV) market has been growing in recent decades. This growth is related to the change in lifestyle and eating habits of consumers who seek practical and healthy food for consumption. Maintaining the characteristics and quality of MPVs is a significant challenge for producers and trade…
Open-circuit potential, potentiodynamic polarization, cyclic voltammetry and electrochemical impedance spectroscopy (EIS) techniques have been used for studying the corrosion of titanium in sodium fluoride solutions of various concentrations (10 -3 to 1.5 M). The potential results showed that the native film on titani…
As both consumers and producers are shifting from fossil-derived materials to other, more sustainable approaches, there is a growing interest in bio-origin and biodegradable polymers. In search of bio-degradable electro-mechanically active materials, cellulose-multi wall carbon nanotube (Cell-CNT) composites are a foc…
The wettability of nanoporous silver fabricated by dealloying was studied before and after stearic acid treatment. The dependencies of both water and glycerol contact angles on the variation of pore size as well as time were investigated. The research shows that nanoporous silver surfaces convert from hydrophilicity t…
The selection of appropriate carbon and loading materials and their corresponding preparation methods is necessary for obtaining high-quality supercapacitors. This paper used loofah as a raw material to prepare a kind of super activated carbon with a large specific surface area. Manganese dioxide was precipitated on t…
