Two-dimensional carbon materials such as the 2D nanoweb-like graphyne membrane are promising as molecular sieves for energy and environmental applications. Based on the application of water purification - the removal of contaminants from wastewater and seawater - here we use molecular dynamics (MD) simulations to inve…
Electric double layer capacitors (EDLCs) were fabricated using biomass derived porous activated carbon as electrode material with 1 M H2SO4 and VOSO4 added 1 M H2SO4 as electrolytes. Here, VOSO4 was used as redox additive to improve the overall performance of EDLC. As expected, the VOSO4 electrolyte showed ∼43% of imp…
Several gold-based catalysts including Au, Au–La(III), Au–Co(II), and Au–Co(III) were prepared and assessed for acetylene hydrochlorination, combining with characterizations of low-temperature N2 adsorption/desorption, thermogravimetric analysis, X-ray diffraction, temperature-programmed reduction, inductively coupled…
Ultrathin nanostructures possess the very essential features of nanomaterials, including quantum-confinement effects and unconventional reactivities, which are determined by the significant structure variations from the bulk material. More and more isolated reports on ultrathin nanostructures and various new phenomena…
The main benefits of edible active coatings are to maintain the quality and extend shelf-life of fresh fruits and prevent microbial spoilage. Chitosan have a wide range of potential application in different fields of chemical sciences, biological systems, food sciences, pharmaceutical and medical industries. Chitosan…
A photoresponsive nano drug delivery system (DDS) was constructed using two new ingredients: fluorescent carbon dots and a quinoline based phototrigger. The strong fluorescent properties of carbon dots have been explored for in vitro cellular imaging application, and the phototrigger ability of quinoline was exploited…
Nanotechnology has gone through a period of rapid growth, thus leading to the constant increase in the application of engineered nanomaterials in daily life. Several different types of nanoparticles have been engineered to be employed in a wide array of applications due to their high surface to volume ratio that leads…
Utilizing the electrical properties of polymer nanocomposites is an important strategy to develop high performance solvent sensors. Here we report the synergistic effect of multi walled carbon nanotubes (MWCNTs) and reduced graphene oxide (RGO) in regulating the sensitivity of the naturally occurring elastomer, natura…
We review the work done on complexes between biopolyelectrolytes such as ionically modified cellulose or chitosan and oppositely charged surfactants. Around equimolarity of the charges one typically observes precipitation but for other mixing ratios one may form long-time stable complexes, where structure and rheology…
BODIPY dyes constitute one of the most efficient class of fluorescent molecules, yet their absorption and emission signatures are hardly predictable with theoretical tools. Here, we use a robust Time-Dependent Density Functional Theory approach that simultaneously accounts for solvent and vibrational effects, in order…
Introduction of S-ethyl groups in all four ortho positions of azobenzene prevents reduction of the azo group by intracellular glutathione, while enhancing the absorptivity to ~10,000 M(-1) cm(-1) in the blue and green regions of the visible spectrum. cis-to-trans isomerization occurs thermally on the minutes timescale…
In recent years, multifunctional nanoparticles (NPs) consisting of either metal (e.g. Au), or magnetic NP (e.g. iron oxide) with other fluorescent components such as quantum dots (QDs) or organic dyes have been emerging as versatile candidate systems for cancer diagnosis, therapy, and macromolecule delivery such as mi…
A novel soft-hard template approach for preparing photoluminescent carbon dots (CDs) with tunable sizes, compositions, crystalline degrees and photoluminescence properties has been developed using four different precursors as carbon sources. The results offer a new strategy for fabrication of monodispersed CDs with we…
Metal ions play important roles in Aβ aggregate deposition and neurotoxicity which involves the formation of reactive oxygen species (ROS). Oxidative stress and metal dysregulation have been considered as therapeutic targets for AD. Herein, a novel double delivery platform has been presented by integrated anti-aggrega…
We present an electrochemical route to synthesize silver nanoplates on seed‐decorated Indium tin oxide (ITO) glass substrate. The nanoplates are several tens of to several hundred nanometers in dimension. The density of nanoplates covered on the substrate can be controlled well by adjusting the amounts of seed. All th…
We report a simple, efficient and versatile method for assembling metal oxide nanomaterial-graphene core-shell structures. An ultraviolet photodetector fabricated from the ZnO nanoparticle-graphene core-shell structures showed high responsivity and fast transient response, which are attributed to the improved carrier…
A novel reducing reagent, Lawesson's reagent (LR), is used to directly reduce graphene oxide (GO) films and single GO sheets. The as-prepared reduced graphene oxide (GOLR) is fully characterized by XPS, Raman, FTIR, 13C NMR and XRD. Most of the oxygen-containing groups are efficiently removed by LR and the conjugated…
Two rarely seen 2D coordination polymers based on huge 36-metal pure lanthanide clusters, {[Gd36(NA)36(OH)49(O)6(NO3)6(N3)3(H2O)20]Cl2·28H2O}n (1) and {[Dy36(NA)36(OH)49(O)6(NO3)6(N3)3(H2O)20]Cl2·28H2O}n (2) (HNA = nicotinic acid), were synthesized and structurally characterized. The spherical Ln36 skeleton can be vie…
Nanowhiskers of crystalline polysaccharides, including cellulose and chitin, have recently been attracting much attention, especially as rigid filler components of novel nanocomposite materials. Good dispersion of these nanowhiskers in aqueous suspensions, which are usually prepared by appropriate acid hydrolysis of n…
Green-emitting phosphor Eu2+ doped NaBaScSi2O7 was synthesized by a solid-state reaction, and the photoluminescence properties were investigated in conjunction with a structural analysis. The crystallographic occupancy of Eu2+ in the Sc silicate NaBaScSi2O7 matrix was studied based on the Rietveld refinements results…
