Cerium oxide nanoparticles (CeO2-NPs) are increasingly used in polishing, engine enhancement agents and many other products. Even though the acute toxicity of CeO2-NPs to plants has been investigated, the long-term effects of CeO2-NPs in the environment are still unknown. The main objective of this study was to invest…
A molecule consisting of a hexathio-benzene core and peripheral tolyl substituents exhibits outstanding phosphorescence properties in some environments favoring rigidity, in the solid state and in a solid matrix at 77 K, while no luminescence is recorded in solution at room temperature. This peculiar behavior is attri…
Silicene, which is the silicon equivalent of carbon-based graphene and shares some of the unique properties with graphene, has been attracting more and more attention since its synthesis and represents a breakthrough in current silicon-based technology. In this work, many-body effects in silicene, silicane, germanene…
We present an investigation of organic photovoltaic (OPV) cells with solution-processable graphene quantum dots (GQDs) as hole transport layers (HTLs). GQDs, with uniform sizes and good conductivity, are demonstrated to be excellent HTLs in both polymer solar cells (PSCs) and small-molecule solar cells (SMSCs) with th…
The efficiency of reducing agents for the reduction of graphene oxide (GO) could be probed by scanning Raman spectroscopy. A film of graphene flakes derived from GO was probed to be graphene like. We also focus on the surface quality of reduced GO (rGO).
Tetrabenzoporphyrins have attracted considerable worldwide attention over the last few decades. Since the discovery of these pigments, chemists, biologists, medical professionals and material scientists have devoted pronounced efforts in order to develop synthetic methods and discover useful applications for these com…
Nowadays, the exploration of zinc oxide nanoparticles (ZnO NPs) based products is booming in the various directions of bio-nanomedicine and other consumer products, but the comprehensive toxicological impact posed by ZnO NPs still remains unclear. The present study systematically investigates and correlates the toxici…
The aim of this work was to establish a novel polymeric mixed micelle composed of Pluronic P105 and F127 copolymers loaded with the poorly soluble antitumor drug docetaxel (DTX) against Taxol-resistant non-small cell lung cancer. A central composite design was utilized to optimize the preparation process, helping to i…
A water soluble perylene diimide molecule has been fabricated into nanofibers via a pH triggered hydrogelation route. The one-dimensional self-assembly is dominated by the intermolecular π-π stacking interactions in concert with the hydrogen bonding between the carboxylic acid side chains. The anisotropic electronic a…
The impact of post-synthetic treatments of nanocrystals (NCs) on the performance of Schottky solar cells, where the active PbS nanocrystal layer is sandwiched directly between two electrodes, is investigated. By monitoring the amount of ligands on the surface of the nanocrystals through Fourier Transform Infrared (FTI…
We investigated the effect of Cd and Hg substitution on the thermoelectric properties of p-type PbTe–x% CdTe and PbTe–x% HgTe (1 ≤ x ≤ 5) doped with Na2Te. Both ingot samples and spark plasma sintered (SPS) samples were studied and the properties are compared. We present detailed structural, spectroscopic and transmis…
Electrochemical synthesis represents a highly efficient method for the fabrication of nanostructured energy materials, and various nanostructures, such as nanorods, nanowires, nanotubes, nanosheets, dendritic nanostructures, and composite nanostructures, can be easily fabricated with advantages of low cost, low synthe…
Biomedical imaging techniques can provide a vast amount of anatomical information, enabling diagnosis and the monitoring of disease and treatment profile. MRI uniquely offers convenient, non-invasive, high resolution tomographic imaging. A considerable amount of effort has been invested, across several decades, in the…
The work on cellulose fiber composites is typically strictly divided into two separated research fields depending on the fiber origin, that is, from wood and from annual plants, representing the two different industries of forest and agriculture, respectively. The present paper evaluates in parallel wood fibers and pl…
We report exceptional electrochemical specific capacitance (640 F g(-1)) for polythiophene (PTh) infiltrated into TiO(2) nanotubes (TNTs) by a controlled electropolymerization route. The resulting PTh-TNTs also exhibit excellent electrochemical behavior with long-term stability. This reproducible and superior performa…
Hexagonal molybdenum oxide (h‐MoO 3 ) nano‐ and microrods were successfully synthesized by refluxing of (NH 4 ) 6 Mo 7 O 24 ·4H 2 O solutions with the pH 1 at 90°C for 1, 3, 5, and 7 h and were further transformed into orthorhombic molybdenum oxide ( α ‐MoO 3 ) microplates by calcination at 450°C for 6 h. These select…
A versatile ethanol-mediated oxidative polymerization of dopamine is demonstrated for the effective surface modification of nanomaterials. The presence of ethanol is found to significantly slow down the polymerization rate of dopamine and make the surface modification of nanomaterials with polydopamine more controllab…
A novel two-dimensional carbon allotrope, rectangular graphyne (R-graphyne) with tetra-rings and acetylenic linkages, is proposed by first-principles calculations. Although the bulk R-graphyne exhibits metallic property, the nanoribbons of R-graphyne show distinct electronic structures from the bulk. The most intrigui…
Recent technological advances in nanotechnology, molecular biology, and imaging technology allow the application of nanomaterials for early and specific cancer detection and therapy. As early detection is a prerequisite for successful treatment, this area of research has been rapidly growing. This paper provides an ov…
This paper presents the results of the experiments undertaken to evaluate various physical and mechanical properties of hemp fibres. The study of these properties is vital for comparison with similar properties of synthetic fibres and for assessing hemp fibres’ suitability for use as reinforcement in composite materia…
