Light structures and parts are very effective for new engineering applications. Their considerably low densities, high energy absorption capabilities, and desirable mechanical properties make them useful for particularly automotive, defense and aerospace industries. Besides these positive properties, it is known that…
Although the electrochemical behaviour of an aqueous dispersion of nanometer-sized redox active nanoparticles has recently received some attention, there are very few such studies of larger objects. Here, we present a study of the electrochemical behaviour of an aqueous dispersion of redox (2,2′-azino-bis-(3-ethylbenz…
It has been proved that surface nanocrstallization pretreatment is beneficial to plasma nitriding of steel by enhancing nitrogen diffusion, while the tribological properties of the nitrided nanostructured steel under boundary lubrication are not clear. In this work, AISI 316 L stainless steel with and without ultrason…
Environmental and economic considerations have made the sorption of uranium from aqueous media a very time demanding area of research from last few decades. In this particular work, amidoximated polyacrylonitrile beads were synthesized by the reaction of hydroxyl amine hydrochloride (OH‐NH2.HCl) with macroporous cross…
In this work, the removal of manganese from nickel melts by Ar and (10%, 20% and 40%) H₂ plasma arc melting under various pressures (0.01⁻0.02, 0.04⁻0.05 and 0.09⁻0.1 MPa) was investigated experimentally. The results show that only a slight reduction in the manganese content is obtained by Ar plasma arc melting (PAM).…
High-strength steel S960 is one of a number of advanced steels able to meet the demands of the shipbuilding, offshore, and construction industries for a favorable good high strength/weight ratio. Gas metal arc welding (GMAW) is commonly used in all structural steel fabrication, and developments in GMAW have removed pr…
Hydroxyapatite (HAp) is a widely explored biomaterial for bone and tooth replacements. Most of the research studies are being carried out in terms of novel routes of synthesis and fabrication in the nano scale to suit its applications. The present research study is unique in two aspects one being the use of seawaste n…
Cold heading quality CHQ steel is widely used for making small components due to its excellent cold heading response. Austenite nucleation and growth morphology of a commercial CHQ steel has been studied by continuous heating experiments using lead-bath up-quenching at different heating temperatures. Modern optical mi…
Wavelength-selective thermal devices have great applications in concentrating solar power systems, high-temperature thermoelectric systems, and solar thermophotovoltaics (STPVs). Lack of high-temperature stability and spectrally selective emissivity in different wavelength regions limits their efficiency. We propose a…
AIM: Despite a significant number of epidemiological studies on potential carcinogenicity of microwave radiation (MWR) from wireless devices and a bulk of experimental studies on oxidative and mutagenic effects of low intensity MWR, the discussion on potential carcinogenicity of low intensity MWR is going on. This stu…
Peripheral arterial disease causes blood vessel dysfunction that requires surgical intervention. Current surgical interventions employ synthetic or allogeneic vascular grafts, which offer biocompatible material solutions that are not able to regenerate or grow with the patient. Decellularized scaffolds have gained sig…
Phasins, the major proteins coating polyhydroxyalkanoate (PHA) granules, have been proposed as suitable biosurfactants for multiple applications because of their amphiphilic nature. In this work, we analyzed the interfacial activity of the amphiphilic α-helical phasin PhaF from Pseudomonas putida KT2440 at different h…
Abstract For ground pulp (GP) utilization in wood fiber composites as reinforced material, its thermal behavior is relevant. The contribution of lignin to thermal performance of GP from Pinus densiflora was the focus of the present study. Dimeric lignin model compounds and isolated milled wood lignins (MWLs) from thre…
Abstract We review two concepts in description of free space in the zeolite-like frameworks: topological (natural tiling) and geometrical-topological (Voronoi net). Advantages and disadvantages as well as similarities and differences of both concepts are discussed. We also consider the packing model of zeolite framewo…
Polyoxometalates have been investigated for use as high-capacity cathode materials in lithium batteries due to their high capacity, cycle stability, and recoverability of crystal structure during charge-discharge. However, POMs have weak points when used as the cathode electrode for lithium batteries: low electronic c…
Asymmetrical n-type molecules are high-performance multifunctional materials simultaneously used as ETMs or ILMs in PVKSCs and electron acceptors in OSCs.
Interests in improving poor interfacial adhesion in carbon fiber‐reinforced polymer (CFRP) composites has always been a hotspot. In this work, four physicochemical surface treatments for enhancing fiber/matrix adhesion are conducted on carbon fibers (CFs) including acid oxidation, sizing coating, silane coupling, and…
In the environment, bacteria can be exposed to the concentration gradient of toxic heavy metals (gradual) or sudden high concentration of them (acute). In both situations, bacteria get acclimated to toxic heavy metal concentrations. Acclimation causes metabolic and molecular changes in bacteria. In this study, we aime…
Nanomaterials have permeated various fields of scientific research, including that of biomedicine, as alternatives for disease diagnosis and therapy. Among different structures, quantum dots (QDs) have distinctive physico-chemical properties sought after in cancer research and eradication. Within the context of cancer…
Breast cancer is a disease where cells in the tissue of the breast, grow and divide without normal control. Breast cancer is second major cause for death in world wide. Importance of natural product increase due to adverse effect of existing synthetic drugs. Asparagus racemosus comprises phytoestrogens which can be us…
