In the present research work, various ceramic materials such as Al2O3 - Cr2O3 - SiC, and Al2O3 - ZrO2 - TiO2 were developed for the analysis of wear performance and hardness. The specimens were coated using plasma spray coating technique. A bond coat of 50 μm thickness was applied on the substrate using NiCrAlY for go…
Macrophages play a major role in the removal of foreign materials, including nano-sized materials, such as nanomedicines and other nanoparticles, which they accumulate very efficiently. Because of this, it is recognized that for a safe development of nanotechnologies and nanomedicine, it is essential to investigate po…
Pharmacological activity of one drug may be altered due to the concomitant administration of another drug, leading to unanticipated drug-drug interactions(DDIs). However, existing DDI prediction approaches are lacking in the following aspects: (1)scalability: they rely heavily on diverse drug-related features, leading…
Abstract The recent development on wearable and stretchable electronics calls for skin conformable power sources that are beyond current battery technologies. Among the many novel energy devices being explored, triboelectric nanogenerator (TENG) made from intrinsically stretchable materials has a great potential to me…
The authors show unconventional multiple edge-state excitations located outside the Bragg band-gap using a space-time modulated topological phononic crystal . The time-modulation induces frequency conversion that can be leveraged to access topological edge states at a deep subwavelength scale where the wavelength is s…
Oral squamous cell carcinoma (OSCC) is one of the main causes of death in oral diseases. With the development of nanotechnology, great progress has been made in the diagnosis and treatment of tumors in nanomedicine. Being able to carry drugs, nucleic acids, contrast agents, and so on, nano-medical technology can effec…
A series of polyethylene-like ionomers with periodic sulfonate groups were synthesized by polyesterification of octatetracontane-1,48-diol and tetrabutylammonium dimethyl sulfosuccinate. Optional cation exchange in aqueous dispersions replaced the NBu 4 + counterions for Na + or Cs + . The defined periodic microstruct…
Injection processing parameters directly influence the final fiber length and may have a negative effect on the mechanical properties of a part. The aim of the work is to investigate and quantify the effects of the injection rate (2/10/50 cm 3 /s) on the fiber length, the distribution, and orientation during injection…
We review the development trends in microwave magnetism and superconductivity over the last five decades. The review contains the key results of recent studies related to the promising areas of modern magnetism and applied physics – spintronics, magnonics, magnon caloritronics, physics of magnonic crystals, spin-wave…
Purpose: To construct nanobubbles (PTX-AMD070 NBs) for targeted delivery of paclitaxel (PTX) and AMD070, examine their performance in ultrasound molecular imaging of breast cancer and cervical cancer and their therapeutic effect combined with ultrasound targeted nanobubble destruction (UTND). Materials and methods: PT…
In this article, Nb heterostructure-based (NaNbO3/Na2Nb4O11) and Nb/Clay-based materials were prepared, characterized and evaluated for the Rhodamine B (C28H31ClN2O3) photodegradation under UV radiation (253.7 nm). As far as this research understands, this is the first time that the photocatalytic activity of the Nb h…
Abstract Hepatocellular carcinoma (HCC) is a common cancer that affects people worldwide with high morbidity and mortality, and its resistance to current chemotherapeutic drugs is a serious concern. Cytotoxicity of silica nanoparticles (Nano-SiO2) towards cancer cells has been reported previously, but the specific mec…
Superhydrophobic surfaces patterned with macroscale (≈1 mm) structures have gained increasing interest in the past years because of their potential in reducing the contact time between impacting liquid drops and the solid surface. The reduced wettability of these surfaces is of interest in numerous technical applicati…
The accumulation of amyloid β (Aβ) triggers a cascade of toxic events in Alzheimer's disease (AD). The KLVFF peptide can interfere with Aβ aggregation. However, the peptide suffers from poor bioavailability and the inability to cross the blood-brain barrier. In this work, we study the possibility of adopting nanomedic…
Abstract Metamaterials have a foundation in electromagnetics, and the unique properties of these metamaterials have found wide applications in acoustics and electrodynamics disciplines. By exploring local resonant effect of the included aggregates in the concrete mix with ellipsoidal coating rubber, a new elastic meta…
A selective and sensitive experimental approach to the examination of lipids as well as lipid–protein interactions in biological membranes using surface-enhanced Raman spectroscopy has been proposed. This approach has been used for probing the intact mitochondria, membranes of erythrocyte ghosts and liposomes.
Abstract The use of ultrasonic radiation showed an advantage over the existing methods of dismantling the windings of electric motors (EM). The method is based on the cavitation impact of ultrasonic vibrations and the capillary effect, which helps the caustic soda solution (NaOH) to quickly penetrate into the thicknes…
Planar transformers are widely used in high- frequency high power density power electronic converters. With the demands of miniaturization, more detailed analysis of thermal stress of the transformers is necessary to enhance its reliability. Due to the strong coupling between the power loss and the distribution of the…
Abstract Geopolymer based cementitious materials were produced to reduce or completely eliminate the use of cement in concrete in which could be incorporated with waste materials. In this study, rice husk ash (RHA) which is a waste having rich in silica content after burnt was intended to be used as based geopolymer.…
Abstract The photocatalytic activity of bare titania and ceria supported mesoporous titania (CeO2/TiO2) catalysts were assessed for the degradation of caffeine by visible light irradiation in absence of the oxidants. Different wt% metal loaded (bare, 0.1, 0.5 and 1.0) materials were synthesised by a sol-gel method usi…
