The crystal structure was determined and the physicochemical properties were studied for tetrapropylammonium pertechnetate and perrhenate. Pr4NMO4 (M = Tc, Re) are isostructural and crystallize as colorless prismatic crystals in the orthorhombic system, space group Pna21, Z = 4. For M = Tc at 25°C, a = 13.22(4) Å, b =…
The goal of this work is to determine the effect of niobium on the kinetics and mechanism of Ti-Al oxidation in air. In order to compare the oxidation kinetics of Ti-Al and Ti-Al with the addition of niobium, isothermal oxidation was performed on Ti-48Al and Ti-46Al-8Nb (in at.%) alloys at 1073 K in synthetic air. Cyc…
Copper oxide (CuO) graphene nanocomposites were prepared by a one-step chemical procedure using copper acetate-adsorbed graphene oxide (GO) as precursors and their potential application in non-enzymatic glucose sensing were also evaluated. The morphology of the as-prepared nanocomposites was characterized by Scanning…
The present study focused on improvement of the enzymatic bioscouring performance by using specific mixed enzymes such as alkaline pectinase, protease, lipase and cellulase enzymes. An attempt was made to study the pectinolytic activity of degrading rate of pectin on organic cotton fabric and removal of wax at various…
The association of organic matter (OM) with minerals in soils that leads to the stabilization of OM has been linked to specific surface area (SSA) and mineralogy. This study investigated the mineral properties and OM stabilization in 12 surface tropical soil samples. The results showed that stable carbon (stable C) wa…
This work deals with several neutron flux measurement instruments and particle transport calculations combined in a method to assess the neutron field in experimental locations in nuclear reactor core or reflector. First test of this method in the TRIGA Mark II of Slovenia led to the assessment of three energy groups…
Abstract Electroless Cu plating was used for flake G powder and CNTs, Cu–G–CNTs (copper/graphite/carbon nanotubes) composites were manufactured by means of powder metallurgical method. The influences of CNTs on the mechanical properties, conductivity properties, friction, and wear performance of the composite were exa…
The assessment of the ageing state of MV/LV distribution transformers is an important issue for operators and managers of the electrical network. The objective of this study is thus to find a simple and robust method to assess the degradation of paper inside transformers. So, this article presents investigations carri…
This paper presents the technical requirements for PEM fuel cell systems to participate as power generation in the Smart Grid. In order to illustrate this, two plants with identical fuel cells are integrated into different system configurations and operated with different management strategies. The aim of this study i…
Abstract The paper presents resistance sensor structures with a graphene sensing layer. The structures were tested concerning their sensitivity to the affects of hydrogen, nitrogen dioxide and steam in an atmosphere of a synthetic air. Investigations have proved that resistance structures with a graphene layer are sen…
Herein, we proposed a facile electrodeposition method to prepare well-defined poly(3,4-ethylenedioxythiophene)/graphene (PEDOT/GR) composite on the glassy carbon electrode (GCE) for the determination of nitrite as an electrochemical sensor. Scanning electron microscopy (SEM), UV-vis spectroscopy (UV-vis) and electroch…
To improve the corrosion resistance of different industrials application, we studied vanadium nitride (VN) and hafnium nitride (HfN) single layer thin film, which were deposited onto Si (100) and AISI 4140 steel substrates via r.f. magnetron sputtering technique in Ar/N2 atmosphere with purity at 99.99% for both V and…
Bioactive glasses are inorganic bone regeneration materials which have been used for bone and cartilage reconstruction in orthopedics, oral, maxillofacial and otological surgery applications, especially based on mainly silicate or phosphate systems [1]. The bioactive glass can be prepared through sol-gel or melting me…
Anthrax is a bacterial disease caused by the aerobic sporeforming bacterium Bacillus anthracis, which is an important pathogen owing to its ability to be used as a terror agent. B. anthracis spores can escape phagocytosis and initiate the germination process even in antimicrobial conditions, such as oxidative stress.…
Carbon emission becomes a serious global issue as it is the major contributor in earth warming. Carbon dioxide management is an emerging field of research to find economically viable ways to reduce the concentration in atmosphere. Herein, we report, the enhancement in carbon dioxide capture capacity of hydrogen exfoli…
Background: Lipoaspirate contains noxious substances derived from liposuction. Therefore, extensive washing is recommended before the lipoaspirate is processed further for culture or fat grafting. Washing a small amount of lipoaspirate may not pose a problem, but washing a large volume of lipoaspirate may be cumbersom…
Metal oxide based resistive random-access-memory (RRAM) often requires a forming process before stable resistive switching can be achieved. Electrical forming usually involves voltages higher than normal switching conditions. It presents a design challenge because additional peripheral circuitry may be needed for this…
Polyaniline/coconut shell–activated carbon (PANI/GAC) composites were fabricated by chemical oxidative polymerization of aniline monomers with GAC as the supporting materials. These prepared PANI/GAC composites were characterized by scanning electron microscopy, N2 adsorption-desorption analysis, and Fourier transform…
The properties of materials synthesized with nanoparticles (NPs) are highly correlated to the sizes and shapes of the nanoparticles. The transmission electron microscopy (TEM) imaging technique can be used to measure the morphological characteristics of NPs, which can be simple circles or more complex irregular polygo…
This paper reports a generic process flow to fabricate mechanically flexible and optically semi-transparent thermoelectric generators (TEGs), micro lithium-ion batteries (μLIB) and metal-oxide-semiconductor capacitors (MOSCAPs) on mono-crystalline silicon fabric platforms from standard bulk silicon (100) wafers.
