The change of distance between individual graphene oxide sheets due to swelling is the key parameter to explain and predict permeation of multilayered graphene oxide (GO) membranes by various solvents and solutions. In situ synchrotron X-ray diffraction study shows that swelling properties of GO membranes are distinct…
Nanoparticles of Zn1-xCuxO system with nominal compositions x = 0.0, 0.01, 0.02 and 0.03 were prepared by co-precipitation method at room temperature. Structural, morphological, optical and chemical species of grown crystals were investigated by X-ray diffraction (XRD) technique, Scanning Electron Microscopy (SEM), UV…
It has been successfully carried out the synthesis of silver nanoparticles by chemical reduction method. Silver nitrate (AgNO3) is used as the metal precursor and trisodium citrate as the reducing agent as well as the use of polyvinyl alcohol (PVA) as a stabilizer. The formation of silver nanoparticles was observed vi…
Covalent triazine frameworks (CTFs) are prepared from amorphous, non-porous polymer networks using a facile and scalable procedure.
Perovskite ferroelectrics (PFs) have been the dominant piezoelectric materials for various electromechanical applications, such as ultrasonic transducers, sensors, and actuators, to name a few. In this review article, the development of PF crystals is introduced, focusing on the crystal growth and piezoelectric activi…
Magnetic resonance imaging (MRI) has become an integral part of modern clinical imaging due to its non-invasiveness and versatility in providing tissue and organ images with high spatial resolution. With the current MRI advancement, MRI imaging probes with suitable biocompatibility, good colloidal stability, enhanced…
One-dimensional MnO 2 -based multiscale micronodules were fabricated through a facile electrodeposition and coating process to produce ultrahigh performance flexible asymmetric supercapacitors.
Engineered metal oxide nanoparticles (MO NPs) are finding increasing utility in the medical field as anticancer agents. Before validation of in vivo anticancer efficacy can occur, a better understanding of whole-animal toxicity is required. We compared the toxicity of seven widely used semiconductor MO NPs made from z…
Nanostructured porous wires of FeCo 2 O 4 supported on nickel foam were synthesized and employed as binder/additive-free electrodes in asymmetric aqueous supercapacitors, showing a high energy density of 23 Wh kg −1 .
This in situ grafting modification offers an effective approach to improve the properties of biocomposite materials from sustainable resources.
Neural network potentials trained by first-principles density functional theory total energies were applied to search for global minima of gold nanoclusters within the basin-hopping method. Using Au58 as an example, we found a new putative global minimum which has a core-shell structure of Au10@Au48 and C4 symmetry. T…
We have developed a low-cost, highly absorbent but degradable, green cellulose aerogel. Furthermore, hydrophobic modification was performed efficiently using cold plasma technology.
Giant enhancement of Nd 3+ –Yb 3+ cascade sensitized upconversion luminescence has been achieved in lanthanide-doped active-core/active-shell nanoparticles.
Today, nanotechnology plays a vital role in biomedical applications, especially for the diagnosis and treatment of various diseases. Among the many different types of fabricated nanoparticles, magnetic metal oxide nanoparticles stand out as unique and useful tools for biomedical applications, because of their imaging…
A new intumescent coating is layer-by-layer deposited on cotton, leading to fire being extinguished after ignition on the fabric during vertical fire testing.
A prerequisite for exploiting most proposed applications for MoS2 is the availability of water-dispersible functionalized MoS2 nanosheets in large quantities. Here we report one-step synthesis and surface functionalization of MoS2 nanosheets by a facile ionic liquid assisted grinding method in the presence of chitosan…
Graphene oxide (GO) was prepared according to a modified Hummers method, and a range of GO/ultrahigh molecular weight polyethylene (UHMWPE) composites were fabricated then their mechanical and thermal properties were investigated.
