AIM: The present study was carried out to determine the effects of ZnO nanoparticles (ZnO-NPs) on intestinal function and pathophysiological alteration. MATERIALS & METHODS: ZnO-NPs were synthesized and their characterizations were performed using various techniques. The Wistar male rats fed with normal diet and/or hi…
BACKGROUND: The harmful effects following the release of nanomaterials into environment are of great concern today. PURPOSE: In this study, subacute effect due to co-exposure to low-dose silica nanoparticles (SiNPs) and lead acetate (Pb) on cardiovascular system was detected in Sprague Dawley male rats. MATERIALS AND…
Rare earth doped/codoped phosphors have been extensively studied for different types of applications based on their intense luminescence features. For this, researchers have tried to choose the inorganic host matrices having both a low phonon cut-off frequency and a high refractive index. Many articles have been publi…
The properties and structures of viruses are directly related to the three-dimensional structure of their capsid proteins, which arises from a combination of hydrophobic and supramolecular interactions, such as hydrogen bonds. The design of synthetic materials demonstrating similar synergistic interactions still remai…
Thermal stability, precision, and large output are desired for applications of electromechanical materials. However, this combination has been hardly attained because both the commercially used materials and currently promising candidates are confronted with a critical challenge: the intrinsic incompatibility among th…
The poor pharmacokinetic parameters and low solubility of many anticancer therapeutics have warranted the use of drug-delivery systems such as liposomes. Overcoming some drawbacks of the conventional liposomes, targeted liposomal delivery by longer circulation time by addition of poly(ethylene glycol) to the liposomal…
Purpose: To evaluate the adverse vascular effects of nanoparticles (NPs) in vitro, extensive studies have investigated the toxicity of NPs on endothelial cells, but the knowledge of potential toxicity on human smooth-muscle cells (SMCs) is currently limited. Methods: This study compared the toxicity of TiO2, ZnO, and…
Graphene photodetectors are highly attractive owing to its ultra-fast and wide-range spectral response from visible to infrared benefit from the superior carrier mobility and the linear dispersion with zero bandgap of graphene. The application of graphene photodetectors however is seriously limited by the low intrinsi…
Three compounds based on heterocyclic amides were synthesized, purified, characterized, and evaluated as corrosion inhibitors for carbon steel in 1.0 M H 2 SO 4 solution using various techniques such as the weight loss, hydrogen evolution, thermometric, and potentiodynamic polarization. Effects of raising the concentr…
The higher critical electric field of β-gallium oxide (Ga2O3) gives promise to the development of next generation power electronic devices with improved size, weight, power, and efficiency over current state-of-the-art wide bandgap devices based on 4H-silicon carbide (SiC) and gallium nitride (GaN). However, it is exp…
It is generally accepted that chemically synthesized nanoparticles lose their ferroelectricity (spontaneous polarization) as the particles become smaller. In contrast, ball-milled ferroelectric nanoparticles have an enhanced ferroelectric response at remarkably small sizes (≤10 nm). Although prior theory suggests that…
Background: Carbon quantum dots (CDots) have recently been reported as a new class of visible light activated antimicrobial nanomaterials. This study reports the synergistic photoactivated antimicrobial interactions of CDots with photosensitizers on bacterial cells. Methods: The antimicrobial effects of the CDots with…
Metasurfaces exploit optical phase, amplitude, and polarization engineering at subwavelength dimensions to achieve unprecedented control of light. The realization of all dielectric metasurfaces has led to low-loss flat optical elements with functionalities that cannot be achieved with metal elements. However, to reach…
Abstract The synthesis of ultrafine and well‐distributed rhodium nanoparticles (NPs) with high efficiency toward methanolysis of ammonia borane (AB) is crucially important but challenging. A facile approach has been developed for synthesizing ultrafine and uniform Rh NPs deposited on carbon by using the small soluble…
We have studied the physical properties of M2InC (M = Zr, Hf and Ta) MAX phases ternary carbides using density functional theory (DFT) methodology. The structural, elastic and electronic properties are revisited (and found to be in good agreement with recently reported results). The charge density distribution, Fermi…
As a widely distributed and fast growing graminaceous plant, bamboo has emerged as an important raw material for pulping and papermaking to mitigate the shortage of wood resources, at least in the East Asia region. New technologies such as silicon removal have been developed to overcome the disadvantage of bamboo as a…
Smart materials and structures with tunable electromagnetic (EM) properties are highly demanded for active environmental sensitive systems. As polar molecules in the environment, in this work, water and ice are utilized as wetting and freezing conditions to manipulate the electromagnetic response behaviors in a graphe…
Developing a high-efficiency and low-cost light source with emission wavelength transparent to silicon is an essential step toward silicon-based nanophotonic devices and micro/nano industry platforms. Here, a near-infrared monolayer MoTe2 light-emitting diode (LED) has been demonstrated and its emission wavelength is…
The mechanochromic luminescence phenomenon was first reported in the low-cost mechanochemical (MC) synthesis process of a covalent organic framework (COF-TpMA (MC)) prepared using triformylphloroglucinol (Tp) and melamine (MA) as precursors, which shows excellent performance as a hydroxyl radical (˙OH) detector in liv…
BACKGROUND: Here, electrospun fibers based on a blend of polycaprolactone (PCL), poly(ethylene glycol) (PEG), and gelatin methacryloyl (GelMA) were developed. The careful choice of this polymer combination allowed for the preparation of a biomaterial that preserved the mechanical strength of PCL, while at the same tim…
