This paper provides a possible solution to minimize the effect of temperature on nano-tube (NT) FETs by applying performance enhancers. Here high-k and dual metal gates(DMG) are used as performance boosters. The high-k downgrades the leakage issues and improves the on-state current(Ion), while dual metal gate suppresses the short-channel-effects (SCEs). Simulation results reflect that Ion […]
Superhydrophobic surfaces (SHSs) exhibit exceptional water repellency characterized by a high contact angle (>150°), extremely low surface energy, and minimal sliding angle (<5°). They demonstrate minimal contact angle hysteresis (<10°) and excellent Cassie-Baxter state stability. These properties, attributed to the surface’s unique micro- and nano-structures or tailored chemical composition, induce a non-wetting behavior. SHSs hold […]
The multifaceted pathophysiology of diabetic wounds coupled with impaired diabetic wound healing remains a significant challenge for the medical community in the 21st century. Possibility of bacterial infections, insufficient vascular supply, increment in levels of oxidative stress, and abnormalities in defenses mechanism of antioxidant causes diabetic foot ulcers (DFU) that leads to significant morbidity. An […]
Magnetic nanoparticles, which make up a large part of nanomaterials, have the potential for clinical diagnosis and treatment due to their unique properties such as magnetic and superparamagnetic torque and the power of biological interactions at the cellular and molecular levels. The unique properties of these nanoparticles include super-saturation, superparamagnetic and magnetic susceptibility, which are […]
In this study, we report the synthesis of magnetite (Fe3O4) nanoparticles using Catha Edulis plant leaf extract as bioreducing agents and investigation of its efficiency as an adsorbent for hexavalent chromium Cr(VI) removal from aqueous solutions. The synthesized NPs were characterized using X-ray diffraction (XRD) spectroscopy, Fourier Transforms Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), […]
In this paper, we optimize the electrical characteristics of Nano-scale symmetric double-gate metal oxide semiconductor field effect transistors (DG-MOSFETs) for digital applications using a genetic algorithm. We use a single-objective genetic algorithm to optimize the threshold voltage (Vth) with a distinct analytical relationship. The optimization of the threshold voltage is accomplished for three cases with […]
Quantum Dots are a group of semiconductors nanomaterials whose size is about less than 10 nm exhibiting unique optical and electric properties which impart different advantages in terms of wide and continuous absorption spectra, narrow emission spectra, high quantum yield, long fluorescence lifetimes, and high photostability. Based on the unique properties of quantum dots have a variety of […]
The effect of milling process on TiO2 nanopowders and functional properties of TiO2 coated cotton fabric was investigated. The XRD analysis reveals that the milled TiO2 nanopowders reduce its size in Nano scale when milling time increases. SEM analysis reveals that the milled TiO2 powder shows a seed-like structure. FTIR spectra show the presence of […]
In this review article, the implementation of nanomaterials such as metal oxides and their composites, carbon nanotubes, dendrimers, and polymer nanocomposites in wastewater decontamination have been discussed. Nanomaterials have a lot of potentials, due to their high pollution sensing ability and larger surface area. Nanomaterials are ideal for eliminating harmful heavy metals and eradicating severe […]
Recently, with the increase in diseases caused by bacterial and viral infections, the need for antibacterial agents has widely increased. On the other hand, with the development of drug resistance to organic groups of antibiotics, new antibiotics have attracted the attention of researchers because new methods are needed to reduce the activity of bacteria. Nanotechnology […]
